本申请要求于2022年12月30日提交中国专利局、申请号为202211730307.8、发明名称为“一种冷凝器及散热***”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese patent application filed with the China Patent Office on December 30, 2022, with application number 202211730307.8 and invention name “A Condenser and Heat Dissipation System”, all contents of which are incorporated by reference in this application.

技术领域Technical Field

本申请涉及散热技术领域，尤其涉及一种冷凝器及散热***。The present application relates to the field of heat dissipation technology, and in particular to a condenser and a heat dissipation system.

背景技术Background technique

随着处理模块功耗越来越高，当前服务器散热已经从风冷走向风液混合甚至全液冷。平行流冷凝器是风液散热器的重要模块，由全铝钎焊而成，具有重量轻，换热表面积大等优点。As the power consumption of processing modules increases, the current server cooling has evolved from air cooling to air-liquid mixed cooling or even full liquid cooling. The parallel flow condenser is an important module of the air-liquid radiator. It is made of all-aluminum brazing and has the advantages of light weight and large heat exchange surface area.

平行流冷凝器可用于单相及两相液冷***，工作压力可达到几Mpa甚至十几Mpa。冷凝器一般由全铝钎焊而成，焊缝数量可达上百条，因此需要在结构和焊接工艺及无损检测方面着手，提高冷凝器的可靠性。Parallel flow condensers can be used in single-phase and two-phase liquid cooling systems, and the working pressure can reach several MPa or even more than ten MPa. Condensers are generally made of all-aluminum brazing, and the number of welds can reach hundreds. Therefore, it is necessary to work on the structure, welding process and non-destructive testing to improve the reliability of the condenser.

现有的平行流冷凝器焊缝形式较为简单，一般采用扁管直接***集流腔焊接，集流腔为单层结构，扁管与集流腔的对插焊接只有单层焊接，焊缝宽度不可控制，若扁管与集流腔的焊接位置存在缺陷，冷却液直接沿焊缝泄漏，不容易拦截，导致冷凝器失效率较高。The existing parallel flow condenser weld form is relatively simple. Generally, a flat tube is directly inserted into the manifold for welding. The manifold is a single-layer structure, and the butt welding between the flat tube and the manifold is only a single-layer welding. The weld width cannot be controlled. If there is a defect in the welding position between the flat tube and the manifold, the coolant will leak directly along the weld and is not easy to intercept, resulting in a high condenser failure rate.

申请内容Application Contents

本申请提供了一种冷凝器及散热***，实现扁管依次穿过集流腔双层侧板，形成双密封结构，提高冷凝器可靠性，降低泄漏失效概率。The present application provides a condenser and a heat dissipation system, which enable flat tubes to sequentially pass through the double-layer side plates of the manifold to form a double-sealed structure, thereby improving the reliability of the condenser and reducing the probability of leakage failure.

本申请提供了一种冷凝器，所述冷凝器包括：The present application provides a condenser, the condenser comprising:

左集流腔组件；Left manifold assembly;

右集流腔组件，所述右集流腔组件与所述左集流腔组件平行设置；A right manifold assembly, wherein the right manifold assembly is arranged in parallel with the left manifold assembly;

扁管，所述扁管的两端分别连接所述左集流腔组件和所述右集流腔组件；A flat tube, two ends of which are respectively connected to the left manifold assembly and the right manifold assembly;

其中，所述左集流腔组件与所述右集流腔组件靠近所述扁管的一侧均具有双层侧板，所述扁管的两端分别穿过对应的所述双层侧板，并与所述双层侧板焊接。Wherein, the left manifold assembly and the right manifold assembly both have double-layer side plates on one side close to the flat tube, and both ends of the flat tube respectively pass through the corresponding double-layer side plates and are welded to the double-layer side plates.

本申请中，左集流腔组件与右集流腔组件之间通过若干扁管相连通。左集流腔组件与右集流腔组件靠近扁管的一侧均设置有双层侧板，扁管依次穿过双层侧板，并与双层侧板焊接，使扁管与左集流腔组件和右集流腔组件均形成双层焊缝，从而形成双密封结构。也就是说，在扁管与右集流腔组件(或左集流腔组件)的焊接位置中，若扁管与其中一侧板的焊接位置发生泄漏，扁管与另一侧板的焊接位置还能够对冷却液进行拦截，减小冷却液直接外漏的风险，进而提高扁管与左集流腔组件和右集流腔组件连接可靠性，降低扁管与左集流腔组件和右集流腔组件连接位置泄漏失效的概率，保证冷凝器工作可靠性。In the present application, the left manifold assembly and the right manifold assembly are connected by a number of flat tubes. Double-layer side plates are provided on the side of the left manifold assembly and the right manifold assembly close to the flat tube. The flat tubes pass through the double-layer side plates in turn and are welded to the double-layer side plates, so that the flat tubes and the left manifold assembly and the right manifold assembly form double-layer welds, thereby forming a double sealing structure. That is to say, in the welding position of the flat tube and the right manifold assembly (or the left manifold assembly), if the welding position of the flat tube and one of the side plates leaks, the welding position of the flat tube and the other side plate can also intercept the coolant, reducing the risk of direct leakage of the coolant, thereby improving the connection reliability of the flat tube and the left manifold assembly and the right manifold assembly, reducing the probability of leakage failure at the connection position of the flat tube and the left manifold assembly and the right manifold assembly, and ensuring the working reliability of the condenser.

在一种可能的设计中，所述左集流腔组件与所述右集流腔组件沿所述扁管对称设置；In a possible design, the left manifold assembly and the right manifold assembly are symmetrically arranged along the flat tube;

所述右集流腔组件包括第一侧板和第一腔体，所述第一腔体设有第一空腔和第二侧板，所述第二侧板靠近所述第一侧板设置，所述扁管的一端依次穿过所述第一侧板和所述第二侧板延伸至所述第一空腔内；The right manifold assembly comprises a first side plate and a first cavity, the first cavity is provided with a first cavity and a second side plate, the second side plate is arranged close to the first side plate, and one end of the flat tube passes through the first side plate and the second side plate in sequence and extends into the first cavity;

所述第一侧板与所述第二侧板为所述双层侧板，所述第一侧板的边缘部与所述第二侧板的边缘部焊接固定。The first side plate and the second side plate are double-layer side plates, and the edge of the first side plate and the edge of the second side plate are welded and fixed.

本申请中，右集流腔组件设有进液口，左集流腔组件设有出液口，吸热的冷却液沿进液口流至左集流腔组件，经左集流腔组件流至各扁管内进行散热，散热后的冷却液再经右集流腔组件的出液口流出。左集流腔组件与右集流腔组件结构大致相同。以右集流腔组件的结构为例进行阐述，扁管的一端依次穿过第一侧板和第二侧板延伸至第一腔体内部，且扁管与第一侧板和第二侧板的插接位置进行焊接，使扁管与第一侧板的插接位置形成第一层焊缝，扁管与第二侧板的插接位置形成第二层焊缝，对扁管与右集流腔组件连接位置提供双层保护。本申请扁管与右集流腔组件的插接位置焊接形成双层焊缝，相比于单层焊缝，双层焊缝失效率低。如，单层焊缝发生泄漏后，冷却液直接沿泄漏点流出，而本实施例设置双层焊缝，在第二层焊缝发生泄漏时，还能通过第一层焊缝对冷却液进行拦截，相比于单层焊缝减小扁管与右集流腔组件插接位置失效的概率，提高扁管与右集流腔组件焊接可靠性。In this application, the right manifold assembly is provided with a liquid inlet, and the left manifold assembly is provided with a liquid outlet. The heat-absorbing coolant flows along the liquid inlet to the left manifold assembly, flows through the left manifold assembly to each flat tube for heat dissipation, and the coolant after heat dissipation flows out through the liquid outlet of the right manifold assembly. The left manifold assembly and the right manifold assembly have roughly the same structure. Taking the structure of the right manifold assembly as an example, one end of the flat tube It extends to the inside of the first cavity through the first side plate and the second side plate in sequence, and the flat tube is welded to the plug-in position of the first side plate and the second side plate, so that the plug-in position of the flat tube and the first side plate forms a first layer of weld, and the plug-in position of the flat tube and the second side plate forms a second layer of weld, providing double-layer protection for the connection position between the flat tube and the right manifold assembly. The plug-in position of the flat tube and the right manifold assembly of the present application is welded to form a double-layer weld, and compared with the single-layer weld, the failure rate of the double-layer weld is low. For example, after a single-layer weld leaks, the coolant flows out directly along the leak point, while the present embodiment is provided with a double-layer weld, and when the second-layer weld leaks, the coolant can also be intercepted by the first layer of weld, which reduces the probability of failure of the plug-in position of the flat tube and the right manifold assembly compared to the single-layer weld, and improves the welding reliability of the flat tube and the right manifold assembly.

其中，在第一侧板与第二侧板中，一者设有第一连接柱，另一者设有第一连接孔，通过第一连接柱与第一连接孔配合，实现第一侧板与第二侧板预连接。也就是说，先通过第一连接柱与第一连接孔的配合，将第一侧板与第二侧板的相对位置进行限定后，再对第一侧板的边缘部与第二侧板的边缘部焊接固定，减小第一侧板与第二侧板焊接前位置发生变动的风险。Among them, one of the first side plate and the second side plate is provided with a first connecting column, and the other is provided with a first connecting hole, and the first side plate and the second side plate are pre-connected by the cooperation of the first connecting column and the first connecting hole. In other words, the relative position of the first side plate and the second side plate is first defined by the cooperation of the first connecting column and the first connecting hole, and then the edge of the first side plate and the edge of the second side plate are welded and fixed, so as to reduce the risk of position change before welding of the first side plate and the second side plate.

在一种可能的设计中，所述第二侧板的中间部分朝远离所述第一侧板的方向凹陷，使所述第一侧板与所述第二侧板之间形成第二空腔。In a possible design, a middle portion of the second side plate is recessed in a direction away from the first side plate, so that a second cavity is formed between the first side plate and the second side plate.

本申请中，冷却液沿第一空腔流向扁管时，若扁管与第二侧板插接位置的第二层焊缝发生泄漏，冷却液会沿第二层焊缝的泄漏点流至第二空腔内，因扁管与第一侧板和第二侧板的插接位置均焊接处理，第二空腔具有较好的密封性，使第二空腔进一步阻挡冷却液外漏。本申请通过设置第二侧板，使第二侧板与第一腔体焊接后形成双腔体结构，扁管依次穿过双腔体后，使扁管与右集流腔组件的插接位置形成双密封结构，实现对冷却液的泄漏进行双重拦截。In the present application, when the coolant flows along the first cavity to the flat tube, if the second layer weld at the plug-in position of the flat tube and the second side plate leaks, the coolant will flow along the leakage point of the second layer weld into the second cavity. Since the plug-in positions of the flat tube and the first side plate and the second side plate are welded, the second cavity has better sealing, which further blocks the leakage of the coolant. The present application sets a second side plate, so that the second side plate and the first cavity are welded to form a double cavity structure. After the flat tube passes through the double cavity in turn, the plug-in position of the flat tube and the right manifold assembly forms a double sealing structure, thereby realizing double interception of the leakage of the coolant.

在一种可能的设计中，所述第二侧板靠近所述第一侧板的一侧设有阻隔部，所述阻隔部将所述第二空腔分隔为上空腔和下空腔；In a possible design, a blocking portion is provided on a side of the second side plate close to the first side plate, and the blocking portion divides the second cavity into an upper cavity and a lower cavity;

所述右集流腔组件还包括第一排气管口和第二排气管口；The right manifold assembly further includes a first exhaust pipe opening and a second exhaust pipe opening;

所述第一排气管口与所述上空腔连通，以能够对所述上空腔检漏；The first exhaust pipe port is in communication with the upper cavity so as to detect leaks in the upper cavity;

所述第二排气管口与所述下空腔连通，以能够对所述下空腔检漏。The second exhaust pipe opening is communicated with the lower cavity so as to detect leaks in the lower cavity.

本申请中，第一排气管口与第二排气管口用于在冷凝器焊接时起到排气作用，焊接完成后，第一排气管口与第二排气管口还能够对第二空腔进行检测。对第二空腔检测时，将第二空腔分割为上下两部分，能够具体检测出第二空腔哪部分发生泄漏，以便于后续维修。具体地，上空腔为独立密封空间，检测上空腔时，通过第一排气管口对上空腔内通入示漏气体氦气，若示漏气体氦气从漏缝泄出，泄漏出的气体进入氦质谱检漏仪中，则上空腔发生泄漏，反之上空腔未发生泄漏。下空腔为独立密封空间，检测下空腔时，通过第二排气管口对下空腔内通入示漏气体氦气，若示漏气体氦气从漏缝泄出，泄漏出的气体进入氦质谱检漏仪中，则下空腔发生泄漏，反之下空腔未发生泄漏。或者，也可采用其他方法对第二空腔进行检漏。In the present application, the first exhaust pipe port and the second exhaust pipe port are used to exhaust the condenser during welding. After welding, the first exhaust pipe port and the second exhaust pipe port can also detect the second cavity. When detecting the second cavity, the second cavity is divided into two parts, the upper and lower parts, so that it can be specifically detected which part of the second cavity is leaking, so as to facilitate subsequent maintenance. Specifically, the upper cavity is an independent sealed space. When detecting the upper cavity, the leak-indicating gas helium is introduced into the upper cavity through the first exhaust pipe port. If the leak-indicating gas helium leaks out from the leak, the leaked gas enters the helium mass spectrometer leak detector, then the upper cavity leaks, and the upper cavity does not leak. The lower cavity is an independent sealed space. When detecting the lower cavity, the leak-indicating gas helium is introduced into the lower cavity through the second exhaust pipe port. If the leak-indicating gas helium leaks out from the leak, the leaked gas enters the helium mass spectrometer leak detector, then the lower cavity leaks, and the lower cavity does not leak. Alternatively, other methods can also be used to detect leaks in the second cavity.

同理，左集流腔组件还包括第三排气管口和第四排气管口，第三排气管口和第四管排气管口除能够在焊接时排气外，还能检测左集流腔组件中对应的空腔是否泄漏。检测方法可以与右集流腔组件的检测方法相同，本申请在此不再赘述。Similarly, the left manifold assembly also includes a third exhaust pipe opening and a fourth exhaust pipe opening, which can not only exhaust during welding, but also detect whether the corresponding cavity in the left manifold assembly is leaking. The detection method can be the same as the detection method of the right manifold assembly, and this application will not repeat it here.

因进液口和出液口与散热***中其他部分相连接，导致进液口与出液口处不便插拔以补注冷却液。为此，右集流腔组件还设有第一注液管口，左集流腔组件设有第二注液管口，第一注液管口与第一腔体相通，第二注液管口与左集流腔组件的第二腔体相通，可通过第一注液管口和第二注液管口向冷凝器内注入冷却液。第一注液管口与第二注液管口除具有补注冷却液作用外，第一注液管口与第二注液管口还能够检测第一空腔与左集流腔组件中对第一空腔相对的空腔是否泄漏。具体地，封堵进液口、出液口和第二注液管口(或第一注液管口)，通过第一注液管口(或第二注液管口)对第一空腔内通入示漏气体氦气，若示漏气体氦气从漏缝泄出，泄漏出的气体进入氦质谱检漏仪中，则发生泄漏，反之未发生泄漏。Because the liquid inlet and the liquid outlet are connected to other parts of the heat dissipation system, it is inconvenient to plug and unplug the liquid inlet and the liquid outlet to replenish the coolant. For this reason, the right manifold assembly is also provided with a first liquid injection nozzle, and the left manifold assembly is provided with a second liquid injection nozzle. The first liquid injection nozzle is communicated with the first cavity, and the second liquid injection nozzle is communicated with the second cavity of the left manifold assembly. The coolant can be injected into the condenser through the first liquid injection nozzle and the second liquid injection nozzle. In addition to replenishing the coolant, the first liquid injection nozzle and the second liquid injection nozzle can also detect whether the first cavity and the cavity opposite to the first cavity in the left manifold assembly are leaking. Specifically, the liquid inlet, the liquid outlet and the second liquid injection nozzle (or the first liquid injection nozzle) are blocked, and the leak-indicating gas helium is introduced into the first cavity through the first liquid injection nozzle (or the second liquid injection nozzle). If the leak-indicating gas helium leaks out from the leak and the leaked gas enters the helium mass spectrometer leak detector, leakage occurs; otherwise, no leakage occurs.

本申请中第一空腔与第二空腔为独立密封腔体，以能够通过对第一空腔与第二空腔进行独立检测，保证第一空腔与第二空腔密封可靠性。在冷凝器使用过程中，第一空腔泄漏的情况下，由于第二空腔的密封性，能够保证冷凝器继续工作。In the present application, the first cavity and the second cavity are independently sealed cavities, so that the sealing reliability of the first cavity and the second cavity can be ensured by independently testing the first cavity and the second cavity. When the condenser is in use, if the first cavity leaks, the condenser can continue to work due to the sealing of the second cavity.

在一种可能的设计中，所述第一侧板设有扁管通道，所述扁管通道外周设有朝向所述第二侧板凸起的凸起部。In a possible design, the first side plate is provided with a flat tube channel, and the outer periphery of the flat tube channel is provided with a protrusion protruding toward the second side plate.

本申请中，通过设置凸起部提高一侧板的结构强度，加强第一侧板对扁管通道的支撑，因凸起部设置在扁管通道的外周，扁管与扁管通道配合时，该凸起部也提高了扁管通道与扁管焊接牢固性。In the present application, the structural strength of one side plate is improved by providing a raised portion, and the support of the first side plate to the flat tube channel is strengthened. The protrusion is arranged on the outer periphery of the flat tube channel. When the flat tube is matched with the flat tube channel, the protrusion also improves the welding firmness between the flat tube channel and the flat tube.

其中，第一侧板可以为双面复合板，第一侧板的表面覆有焊料，第一侧板与扁管焊接时，焊料受热融化实现第一侧板与扁管焊接，无需在扁管与第一侧板的插接处设置焊带，节省空间。Among them, the first side panel can be a double-sided composite panel, and the surface of the first side panel is covered with solder. When the first side panel is welded to the flat tube, the solder melts due to heat to realize the welding of the first side panel and the flat tube. There is no need to set a welding strip at the joint between the flat tube and the first side panel, thus saving space.

在一种可能的设计中，所述第二侧板设有扁管槽，所述扁管槽设有导向部，用于导向所述扁管插至所述扁管槽。In a possible design, the second side plate is provided with a flat tube groove, and the flat tube groove is provided with a guide portion for guiding the flat tube to be inserted into the flat tube groove.

本申请中，扁管槽的靠近第一侧板的一侧设有导向部，导向部对扁管与扁管槽的插接起导向作用，使扁管能够快速插至扁管槽。该导向部可以为斜面，朝靠近第一侧板的方向，导向部使扁管槽的槽口逐渐增大。In the present application, a guide portion is provided on one side of the flat tube groove close to the first side plate, and the guide portion guides the insertion of the flat tube and the flat tube groove, so that the flat tube can be quickly inserted into the flat tube groove. The guide portion can be an inclined surface, and the guide portion gradually increases the notch of the flat tube groove toward the direction close to the first side plate.

在一种可能的设计中，所述第二侧板设有固定部，所述固定部能够固定焊接所述扁管与所述扁管槽的焊片。In a possible design, the second side plate is provided with a fixing portion, and the fixing portion can fix a welding piece for welding the flat tube and the flat tube groove.

本申请中，焊片设置有若干个与固定部配合的固定孔，通过固定孔与固定部的配合，使焊片设置在第二侧板上，便于装配，提高焊接一致性。焊片还设有避让孔，避让孔用于避让扁管穿过，避让孔的数量与扁管的数量相对设置，相邻避让孔之间的焊料部位于扁管与扁管槽配合位置的上方，以在焊料部融化后焊接扁管与第二侧板。焊片还设有避让槽，避让槽用于避让阻隔部。焊片融化后，多余焊料能够流向导向部，填充导向部与扁管之间的缝隙，保证扁管与第二侧板焊接牢固性。In the present application, the welding piece is provided with a plurality of fixing holes matched with the fixing part. Through the matching of the fixing holes and the fixing part, the welding piece is set on the second side plate, which is convenient for assembly and improves the welding consistency. The welding piece is also provided with avoidance holes, which are used to avoid the flat tubes from passing through. The number of avoidance holes is relatively set to the number of flat tubes. The solder part between adjacent avoidance holes is located above the matching position of the flat tube and the flat tube groove, so as to weld the flat tube and the second side plate after the solder part melts. The welding piece is also provided with an avoidance groove, which is used to avoid the barrier part. After the welding piece melts, the excess solder can flow to the guide part, fill the gap between the guide part and the flat tube, and ensure the welding firmness of the flat tube and the second side plate.

在一种可能的设计中，所述第一腔体设有限位部，所述限位部能够限制所述扁管插至所述第一空腔的位置。In a possible design, the first cavity is provided with a limiting portion, and the limiting portion can limit the position of the flat tube inserted into the first cavity.

本申请中，限位部位于第二侧板远离第一侧板的一侧，扁管***第一空腔内的端部与限位部抵接，限制部能够限制各扁管继续朝第一空腔内运动，以限制扁管的端部插至第一空腔内的位置，避免扁管的端部***第一空腔过长，影响扁管的另一端与左集流腔组件焊接效果。或者，避免扁管的端部***第一空腔过短，影响扁管与第二侧板焊接效果。In the present application, the limiting part is located on the side of the second side plate away from the first side plate, and the end of the flat tube inserted into the first cavity abuts against the limiting part. The limiting part can limit the flat tubes from continuing to move into the first cavity, so as to limit the position of the end of the flat tube inserted into the first cavity, thereby preventing the end of the flat tube from being inserted into the first cavity too long, thereby affecting the welding effect of the other end of the flat tube and the left manifold assembly. Alternatively, preventing the end of the flat tube from being inserted into the first cavity too short, thereby affecting the welding effect of the flat tube and the second side plate.

在一种可能的设计中，所述右集流腔组件还包括第三侧板，所述第三侧板位于所述第一腔体远离所述第一侧板的一侧；In a possible design, the right manifold assembly further includes a third side plate, and the third side plate is located on a side of the first cavity away from the first side plate;

所述第一腔体还设有支撑部，所述支撑部的两端分别与所述第二侧板和所述第三侧板连接。The first cavity is further provided with a supporting portion, and two ends of the supporting portion are respectively connected to the second side plate and the third side plate.

本申请中，第三侧板与第一腔体中，一者设有第二连接柱，另一者这有第二连接孔，通过第二连接柱与第二连接孔配合，实现第三侧板与第一腔体连接。也就是说，先通过第二连接柱与第二连接孔的配合，将第三侧板和第一腔体的相对位置进行限定后，再对第三侧板的边缘部与第一腔体靠近第三侧板一侧的边缘部焊接，减小第三侧板与第一腔体焊接前位置发生变动的风险。因第三侧板与第一腔体的焊接位置位于边缘，还可采用超声波等无损检测对第三侧板与第一腔体的焊接位置进行检测，提高冷凝器的焊接合格率和密封可靠性。本申请通过设置支撑部，提高第一腔体的耐压强度，减小第一空腔泄漏的风险。In the present application, one of the third side plate and the first cavity is provided with a second connecting column, and the other has a second connecting hole, and the third side plate is connected to the first cavity by the cooperation between the second connecting column and the second connecting hole. That is to say, the relative position of the third side plate and the first cavity is first defined by the cooperation between the second connecting column and the second connecting hole, and then the edge of the third side plate is welded to the edge of the first cavity close to the third side plate, thereby reducing the risk of position change before the third side plate and the first cavity are welded. Since the welding position between the third side plate and the first cavity is located at the edge, the welding position between the third side plate and the first cavity can also be detected by non-destructive testing such as ultrasonic waves, thereby improving the welding qualification rate and sealing reliability of the condenser. The present application improves the pressure resistance of the first cavity and reduces the risk of leakage of the first cavity by providing a support portion.

在一种可能的设计中，所述第一腔体设有避让部，所述避让部靠近所述第一侧板与所述第二侧板的焊接位置设置。In a possible design, the first cavity is provided with an avoidance portion, and the avoidance portion is arranged close to a welding position between the first side plate and the second side plate.

本申请中，通过设置避让部，无需对冷凝器的结构进行破坏，即可使第一侧板与第二侧板的焊接位置可以实现超声波等无损检测，提高冷凝器的焊接合格率和密封可靠性。In the present application, by setting up the avoidance portion, the welding position of the first side plate and the second side plate can be subjected to non-destructive testing such as ultrasonic testing without destroying the structure of the condenser, thereby improving the welding qualification rate and sealing reliability of the condenser.

在一种可能的设计中，所述冷凝器还包括滤网；In a possible design, the condenser further includes a filter;

所述滤网安装于所述第一空腔内，与所述扁管插至所述第一空腔内的端口相对设置。The filter screen is installed in the first cavity and is arranged opposite to the port where the flat tube is inserted into the first cavity.

本申请中，滤网由高密度金属丝编织而成，如不锈钢滤网。该过滤网起到过滤杂质作用，避免大颗粒杂质参与循环，进入泵或冷板铲齿等其他部件造成影响，提升***使用寿命。In this application, the filter is woven from high-density metal wires, such as a stainless steel filter. The filter plays a role in filtering impurities, preventing large particles of impurities from participating in the circulation and entering other components such as the pump or the cold plate shovel teeth to cause an impact, thereby increasing the service life of the system.

在一种可能的设计中，所述左集流腔组件设有相连通的出液口和第二腔体；In a possible design, the left manifold assembly is provided with a liquid outlet and a second cavity that are connected;

所述冷凝器还包括气液分离管，所述气液分离管的一端与所述出液口连接，另一端延伸至所述第二腔体内液面以下位置。The condenser further comprises a gas-liquid separation tube, one end of which is connected to the liquid outlet, and the other end of which extends to a position below the liquid level in the second cavity.

本申请中，当进液口输入的冷却液混有气体，混有气体的冷却液沿扁管流至第二腔体时，由于气液分离管的一端在第二腔体内液面以下的位置，气体会自动上浮，实现气液分离，因气液分离管的另一端与出液口连接，气液不能沿气液分离管流动至出液口，以及沿出液口流动至***内，避免气液混输加剧***腐蚀、降低换热效率。In the present application, when the coolant input into the liquid inlet is mixed with gas and the coolant mixed with gas flows along the flat tube to the second cavity, since one end of the gas-liquid separation tube is below the liquid level in the second cavity, the gas will automatically float up to achieve gas-liquid separation. Since the other end of the gas-liquid separation tube is connected to the liquid outlet, the gas and liquid cannot flow along the gas-liquid separation tube to the liquid outlet, and flow along the liquid outlet into the system, thereby avoiding gas-liquid mixing, which aggravates system corrosion and reduces heat exchange efficiency.

在一种可能的设计中，所述冷凝器还包括储液腔，所述储液腔的两端分别连通所述第一腔体和所述第二腔体；In a possible design, the condenser further includes a liquid storage cavity, the two ends of which are connected to the first cavity and the The second cavity;

所述储液腔靠近所述第一腔体的一侧设有挡板，所述挡板能够阻挡部分冷却液沿所述第一腔体流入所述储液腔内。A baffle is provided on one side of the liquid storage cavity close to the first cavity, and the baffle can block part of the cooling liquid from flowing into the liquid storage cavity along the first cavity.

本申请中，储液腔用于存储冷却液，在冷凝器内循环冷却液减少时，可通过储液腔补入。因储液腔的流道较大，通过设置挡板，对储液腔进行减流，以使大部分冷却液流向扁管。In the present application, the liquid storage cavity is used to store the coolant, and when the circulating coolant in the condenser is reduced, it can be replenished through the liquid storage cavity. Because the flow channel of the liquid storage cavity is large, the flow of the liquid storage cavity is reduced by setting a baffle, so that most of the coolant flows to the flat tube.

在一种可能的设计中，所述双层侧板为一体成型；In a possible design, the double-layer side panels are integrally formed;

所述双层侧板设有扁管通道。The double-layer side plate is provided with a flat tube channel.

本申请中，左集流腔组件与右集流腔组件可以为一体成型，形成双层空腔，使双层空腔形成的双层侧板也为一体成型。扁管沿扁管通道依次穿过双层侧板，与双层侧板形成双层焊缝，进而形成双层密封结构。在第一空腔的焊缝发生泄漏时，第二空腔能够还能够阻挡冷却液外漏，提高冷凝器工作稳定性。本实施例中左集流腔组件与右集流腔组件采用一体成型工艺制作，提高生产效率，降低生产成本。采用一体成型制作便于设置第二空腔，通过设置第二空腔减小第二层焊缝失效带来的散热性能损失。In the present application, the left manifold assembly and the right manifold assembly can be integrally formed to form a double-layer cavity, so that the double-layer side plate formed by the double-layer cavity is also integrally formed. The flat tubes pass through the double-layer side plates in sequence along the flat tube channels, forming a double-layer weld with the double-layer side plates, thereby forming a double-layer sealing structure. When the weld of the first cavity leaks, the second cavity can also prevent the coolant from leaking out, thereby improving the working stability of the condenser. In this embodiment, the left manifold assembly and the right manifold assembly are manufactured using an integral molding process to improve production efficiency and reduce production costs. The use of integral molding facilitates the setting of the second cavity, and the loss of heat dissipation performance caused by the failure of the second layer of welds is reduced by setting the second cavity.

如图1所示，本实施例提供了一种冷凝器1，冷凝器1包括左集流腔组件11、右集流腔组件12和若干扁管13，右集流腔组件12与左集流腔组件11平行设置，扁管13的两端分别连接左集流腔组件11和右集流腔组件12。右集流腔组件12设有进液口128，左集流腔组件11设有出液口111，吸热的冷却液沿进液口128流至左集流腔组件11，经左集流腔组件11流至各扁管13内进行散热，散热后的冷却液再经右集流腔组件12的出液口111流出。其中，左集流腔组件11与右集流腔组件12靠近扁管13的一侧均具有双层侧板，扁管13的两端分别穿过对应的双层侧板，并与双层侧板焊接。As shown in FIG1 , this embodiment provides a condenser 1, which includes a left manifold assembly 11, a right manifold assembly 12 and a plurality of flat tubes 13. The right manifold assembly 12 is arranged in parallel with the left manifold assembly 11, and the two ends of the flat tubes 13 are respectively connected to the left manifold assembly 11 and the right manifold assembly 12. The right manifold assembly 12 is provided with a liquid inlet 128, and the left manifold assembly 11 is provided with a liquid outlet 111. The heat-absorbing coolant flows along the liquid inlet 128 to the left manifold assembly 11, flows through the left manifold assembly 11 to each flat tube 13 for heat dissipation, and the coolant after heat dissipation flows out through the liquid outlet 111 of the right manifold assembly 12. Among them, the left manifold assembly 11 and the right manifold assembly 12 have double-layer side plates on one side close to the flat tube 13, and the two ends of the flat tube 13 respectively pass through the corresponding double-layer side plates and are welded to the double-layer side plates.

本实施例中，左集流腔组件11与右集流腔组件12之间通过若干扁管13相连通。左集流腔组件11与右集流腔组件12靠近扁管13的一侧均设置有双层侧板，扁管13依次穿过双层侧板，并与双层侧板焊接，使扁管13与左集流腔组件11和右集流腔组件12均形成双层焊缝，从而形成双密封结构。也就是说，在扁管13与右集流腔组件12(或左集流腔组件11)的焊接位置中，若扁管13与其中一侧板的焊接位置发生泄漏，扁管13与另一侧板的焊接位置还能够对冷却液进行拦截，减小冷却液直接外漏的风险，进而提高扁管13与左集流腔组件11和右集流腔组件12连接可靠性，降低扁管13与左集流腔组件11和右集流腔组件12连接位置泄漏失效的概率，保证冷凝器1工作可靠性。In this embodiment, the left manifold assembly 11 and the right manifold assembly 12 are connected by a plurality of flat tubes 13. Double-layer side plates are provided on the side of the left manifold assembly 11 and the right manifold assembly 12 close to the flat tubes 13. The flat tubes 13 pass through the double-layer side plates in turn and are welded with the double-layer side plates, so that the flat tubes 13 and the left manifold assembly 11 and the right manifold assembly 12 form double-layer welds, thereby forming a double sealing structure. That is to say, in the welding position of the flat tubes 13 and the right manifold assembly 12 (or the left manifold assembly 11), if the welding position of the flat tubes 13 and one of the side plates leaks, the welding position of the flat tubes 13 and the other side plate can also intercept the coolant, reducing the risk of direct leakage of the coolant, thereby improving the connection reliability of the flat tubes 13 and the left manifold assembly 11 and the right manifold assembly 12, reducing the probability of leakage failure at the connection position of the flat tubes 13 and the left manifold assembly 11 and the right manifold assembly 12, and ensuring the working reliability of the condenser 1.

如图1至图3所示，具体地，左集流腔组件11与右集流腔组件12沿扁管13对称设置，左集流腔组件11与右集流腔组件12结构大致相同。以右集流腔组件12的结构为例进行阐述，右集流腔组件12包括第一侧板121和第一腔体122，第一腔体122靠近第一侧板121的一侧设有第二侧板122b，第一腔体122还设有第一空腔122a，第一侧板121与第二侧板122b为双层侧板，扁管13的一端依次穿过第一侧板121和第二侧板122b延伸至第一腔体122内部，且扁管13与第一侧板121和第二侧板122b的插接位置进行焊接，使扁管13与第一侧板121的插接位置形成第一层焊缝，扁管13与第二侧板122b的插接位置形成第二层焊缝，对扁管13与右集流腔组件12连接位置提供双层保护。本实施例扁管13与右集流腔组件12的插接位置焊接形成双层焊缝，相比于单层焊缝，双层焊缝失效率低。如，单层焊缝发生泄漏后，冷却液直接沿泄漏点流出，而本实施例设置双层焊缝，在第二层焊缝发生泄漏时，还能通过第一层焊缝对冷却液进行拦截，相比于单层焊缝减小扁管13与右集流腔组件12插接位置失效的概率，提高扁管13与右集流腔组件12焊接可靠性。As shown in FIG. 1 to FIG. 3 , specifically, the left manifold assembly 11 and the right manifold assembly 12 are symmetrically arranged along the flat tube 13 , and the left manifold assembly 11 and the right manifold assembly 12 have substantially the same structure. Taking the structure of the right manifold assembly 12 as an example, the right manifold assembly 12 includes a first side plate 121 and a first cavity 122. A second side plate 122b is provided on the side of the first cavity 122 close to the first side plate 121. The first cavity 122 is also provided with a first cavity 122a. The first side plate 121 and the second side plate 122b are double-layer side plates. One end of the flat tube 13 passes through the first side plate 121 and the second side plate 122b in sequence and extends to the inside of the first cavity 122. The flat tube 13 is welded to the plug-in position of the first side plate 121 and the second side plate 122b, so that the plug-in position of the flat tube 13 and the first side plate 121 forms a first layer of weld, and the plug-in position of the flat tube 13 and the second side plate 122b forms a second layer of weld, providing double-layer protection for the connection position between the flat tube 13 and the right manifold assembly 12. The plug-in position of the flat tube 13 and the right manifold assembly 12 in this embodiment The double-layer weld is formed by welding, and the failure rate of the double-layer weld is low compared with the single-layer weld. For example, after a single-layer weld leaks, the coolant flows out directly along the leaking point, while the double-layer weld is provided in this embodiment. When the second-layer weld leaks, the coolant can be intercepted by the first-layer weld. Compared with the single-layer weld, the probability of failure of the plug-in position of the flat tube 13 and the right manifold assembly 12 is reduced, and the welding reliability of the flat tube 13 and the right manifold assembly 12 is improved.

其中，在第一侧板121与第二侧板122b中，一者设有第一连接柱，另一者设有第一连接孔，通过第一连接柱与第一连接孔配合，实现第一侧板121与第二侧板122b预连接。也就是说，先通过第一连接柱与第一连接孔的配合，将第一侧板121与第二侧板122b的相对位置进行限定后，再对第一侧板121的边缘部与第二侧板122b的边缘部焊接固定，减小第一侧板121与第二侧板122b焊接前位置发生变动的风险。Among them, one of the first side plate 121 and the second side plate 122b is provided with a first connection column, and the other is provided with a first connection hole, and the first connection column cooperates with the first connection hole to achieve pre-connection of the first side plate 121 and the second side plate 122b. In other words, the relative position of the first side plate 121 and the second side plate 122b is first defined by the cooperation of the first connection column and the first connection hole, and then the edge of the first side plate 121 and the edge of the second side plate 122b are welded and fixed, thereby reducing the risk of position change of the first side plate 121 and the second side plate 122b before welding.

如图2和图3所示，在一些实施例中，第二侧板122b的中间部分朝远离第一侧板121的方向凹陷，使第一侧板121与第二侧板122b之间形成第二空腔122c。冷却液沿第一空腔122a流向扁管13时，若扁管13与第二侧板122b插接位置的第二层焊缝发生泄漏，冷却液会沿第二层焊缝的泄漏点流至第二空腔122c内，因扁管13与第一侧板121和第二侧板122b的插接位置均焊接处理，第二空腔122c具有较好的密封性，使第二空腔122c进一步阻挡冷却液外漏。本实施例通过设置第二侧板122b，使第二侧板122b与第一腔体122焊接后形成双腔体结构，扁管13依次穿过双腔体后，使扁管13与右集流腔组件12的插接位置形成双密封结构，实现对冷却液的泄漏进行双重拦截。As shown in FIG. 2 and FIG. 3, in some embodiments, the middle portion of the second side plate 122b is recessed in a direction away from the first side plate 121, so that a second cavity 122c is formed between the first side plate 121 and the second side plate 122b. When the coolant flows along the first cavity 122a to the flat tube 13, if the second layer of welds at the plug-in position of the flat tube 13 and the second side plate 122b leaks, the coolant will flow into the second cavity 122c along the leaking point of the second layer of welds. Since the plug-in positions of the flat tube 13 and the first side plate 121 and the second side plate 122b are all welded, the second cavity 122c has better sealing, so that the second cavity 122c further prevents the coolant from leaking out. In this embodiment, a second side plate 122b is provided so that the second side plate 122b and the first cavity 122 are welded to form a double cavity structure. After the flat tube 13 passes through the double cavity in sequence, a double sealing structure is formed at the plug-in position of the flat tube 13 and the right manifold assembly 12, thereby achieving double interception of coolant leakage.

如图6所示，在一些实施例中，第二侧板122b靠近第一侧板121的一侧设有阻隔部122b1，阻隔部122b1将第二空腔122c分隔为上空腔122c1和下空腔122c2，使上空腔122c1与下空腔122c2分别为独立密封空间。右集流腔组件12还包括第一排气管口123和第二排气管口124，第一排气管口123与上空腔122c1连通，以能够对上空腔122c1检漏，第二排气管口124与下空腔122c2连通，以能够对下空腔122c2检漏。As shown in FIG6 , in some embodiments, a barrier portion 122b1 is provided on one side of the second side plate 122b close to the first side plate 121, and the barrier portion 122b1 separates the second cavity 122c into an upper cavity 122c1 and a lower cavity 122c2, so that the upper cavity 122c1 and the lower cavity 122c2 are independent sealed spaces. The right manifold assembly 12 further includes a first exhaust pipe port 123 and a second exhaust pipe port 124, the first exhaust pipe port 123 is communicated with the upper cavity 122c1 to detect leaks in the upper cavity 122c1, and the second exhaust pipe port 124 is communicated with the lower cavity 122c2 to detect leaks in the lower cavity 122c2.

本实施例中，第一排气管口123与第二排气管口124用于在冷凝器1焊接时起到排气作用，焊接完成后，第一排气管口123与第二排气管口124还能够对第二空腔122c进行检测。对第二空腔122c检测时，将第二空腔122c分割为上下两部分，能够具体检测出第二空腔122c哪部分发生泄漏，以便于后续维修。具体地，上空腔122c1为独立密封空间，检测上空腔122c1时，通过第一排气管口123对上空腔122c1内通入示漏气体氦气，若示漏气体氦气从漏缝泄出，泄漏出的气体进入氦质谱检漏仪中，则上空腔122c1发生泄漏，反之上空腔122c1未发生泄漏。下空腔122c2为独立密封空间，检测下空腔122c1时，通过第二排气管口124对下空腔122c2内通入示漏气体氦气，若示漏气体氦气从漏缝泄出，泄漏出的气体进入氦质谱检漏仪中，则下空腔122c2发生泄漏，反之下空腔122c2未发生泄漏。或者，也可采用其他方法对第二空腔122c进行检漏。In this embodiment, the first exhaust pipe port 123 and the second exhaust pipe port 124 are used to exhaust gas when the condenser 1 is welded. After welding, the first exhaust pipe port 123 and the second exhaust pipe port 124 can also detect the second cavity 122c. When detecting the second cavity 122c, the second cavity 122c is divided into an upper and lower part, and it is possible to specifically detect which part of the second cavity 122c is leaking, so as to facilitate subsequent maintenance. Specifically, the upper cavity 122c1 is an independent sealed space. When detecting the upper cavity 122c1, the leak-indicating gas helium is introduced into the upper cavity 122c1 through the first exhaust pipe port 123. If the leak-indicating gas helium leaks out from the leak and the leaked gas enters the helium mass spectrometer leak detector, the upper cavity 122c1 leaks. On the contrary, the upper cavity 122c1 does not leak. The lower cavity 122c2 is an independent sealed space. When detecting the lower cavity 122c1, helium, a leak-indicating gas, is introduced into the lower cavity 122c2 through the second exhaust pipe port 124. If the leak-indicating gas helium leaks out from the leak and enters the helium mass spectrometer leak detector, the lower cavity 122c2 leaks. Otherwise, the lower cavity 122c2 does not leak. Alternatively, other methods may be used to detect leaks in the second cavity 122c.

同理，左集流腔组件11还包括第三排气管口113和第四排气管口114，第三排气管口113和第四管排气管口除能够在焊接时排气外，还能检测左集流腔组件11中对应的空腔是否泄漏。检测方法可以与右集流腔组件12的检测方法相同，本实施例在此不再赘述。Similarly, the left manifold assembly 11 further includes a third exhaust pipe port 113 and a fourth exhaust pipe port 114. The third exhaust pipe port 113 and the fourth exhaust pipe port can not only exhaust during welding, but also detect whether the corresponding cavity in the left manifold assembly 11 leaks. The detection method can be the same as the detection method of the right manifold assembly 12, and this embodiment will not be repeated here.

如图4和图5所示，在一些实施例中，因进液口128和出液口111与散热***中其他部分相连接，导致进液口128与出液口111处不便插拔以补注冷却液。为此，右集流腔组件12还设有第一注液管口127，左集流腔组件11设有第二注液管口115，第一注液管口127与第一腔体122相通，第二注液管口115与左集流腔组件11的第二腔体112相通，可通过第一注液管口127和第二注液管口115向冷凝器1内注入冷却液。第一注液管口127与第二注液管口115除具有补注冷却液作用外，第一注液管口127与第二注液管口115还能够检测第一空腔122a与左集流腔组件11中对第一空腔122a相对的空腔是否泄漏。具体地，封堵进液口128、出液口111和第二注液管口115(或第一注液管口127)，通过第一注液管口127(或第二注液管口115)对第一空腔122a内通入示漏气体氦气，若示漏气体氦气从漏缝泄出，泄漏出的气体进入氦质谱检漏仪中，则发生泄漏，反之未发生泄漏。As shown in FIG. 4 and FIG. 5 , in some embodiments, the liquid inlet 128 and the liquid outlet 111 are connected to other parts of the heat dissipation system, which makes it inconvenient to plug and unplug the liquid inlet 128 and the liquid outlet 111 to replenish the coolant. For this reason, the right manifold assembly 12 is also provided with a first liquid injection nozzle 127, and the left manifold assembly 11 is provided with a second liquid injection nozzle 115. The first liquid injection nozzle 127 is communicated with the first cavity 122, and the second liquid injection nozzle 115 is communicated with the second cavity 112 of the left manifold assembly 11. The coolant can be injected into the condenser 1 through the first liquid injection nozzle 127 and the second liquid injection nozzle 115. In addition to the function of replenishing the coolant, the first liquid injection nozzle 127 and the second liquid injection nozzle 115 can also detect whether the first cavity 122a and the cavity opposite to the first cavity 122a in the left manifold assembly 11 are leaking. Specifically, the liquid inlet 128, the liquid outlet 111 and the second liquid injection nozzle 115 (or the first liquid injection nozzle 127) are blocked, and the leak-indicating gas helium is introduced into the first cavity 122a through the first liquid injection nozzle 127 (or the second liquid injection nozzle 115). If the leak-indicating gas helium leaks out from the leak and the leaked gas enters the helium mass spectrometer leak detector, leakage occurs; otherwise, no leakage occurs.

本实施例中，第一空腔122a与第二空腔122c为独立密封腔体，以能够对第一空腔122a与第二空腔122c进行独立检测，保证第一空腔122a与第二空腔122c密封可靠性。在冷凝器1使用过程中，第一空腔122a泄漏的情况下，由于第二空腔122c的密封性，能够保证冷凝器1继续工作。In this embodiment, the first cavity 122a and the second cavity 122c are independently sealed cavities, so that the first cavity 122a and the second cavity 122c can be independently detected to ensure the sealing reliability of the first cavity 122a and the second cavity 122c. During the use of the condenser 1, if the first cavity 122a leaks, the condenser 1 can continue to work due to the sealing of the second cavity 122c.

如图7所示，在一些实施例中，第一侧板121设有扁管通道121a，扁管13的一端插接在扁管通道121a内并朝第二侧板122b延伸，扁管通道121a外周设有朝向第二侧板122b凸起的凸起部121b。通过设置凸起部121b提高一侧板的结构强度，加强第一侧板121对扁管通道121a的支撑，因凸起部121b设置在扁管通道121a的外周，扁管13与扁管通道121a配合时，该凸起部121b也提高了扁管通道121a与扁管13焊接牢固性。As shown in FIG. 7 , in some embodiments, the first side plate 121 is provided with a flat tube channel 121a, one end of the flat tube 13 is inserted into the flat tube channel 121a and extends toward the second side plate 122b, and the outer periphery of the flat tube channel 121a is provided with a protrusion 121b protruding toward the second side plate 122b. The protrusion 121b is provided to improve the structural strength of one side plate, strengthen the support of the first side plate 121 for the flat tube channel 121a, and because the protrusion 121b is provided on the flat tube, the protrusion 121b is provided on the flat tube. At the outer periphery of the channel 121 a , when the flat tube 13 is matched with the flat tube channel 121 a , the protrusion 121 b also improves the welding firmness between the flat tube channel 121 a and the flat tube 13 .

其中，第一侧板121可以为双面复合板，第一侧板121的表面覆有焊料，第一侧板121与扁管13焊接时，焊料受热融化实现第一侧板121与扁管13焊接，无需在扁管13与第一侧板121的插接处设置焊带，节省空间。Among them, the first side panel 121 can be a double-sided composite panel, and the surface of the first side panel 121 is covered with solder. When the first side panel 121 is welded to the flat tube 13, the solder melts due to heat to realize the welding of the first side panel 121 and the flat tube 13. There is no need to set a welding strip at the joint between the flat tube 13 and the first side panel 121, thereby saving space.

如图6所示，第二侧板122b设有若干个固定部122b3，第二侧板122b还设有扁管槽122b2，扁管13沿扁管槽122b2穿过第二侧板122b，固定部122b3能够固定焊接扁管13与扁管槽122b2的焊片125，该固定部122b3为均布在第二侧板122b的铆接凸点。焊片125设置有若干个与固定部122b3配合的固定孔，通过固定孔与固定部122b3的配合，使焊片125设置在第二侧板122b上，便于装配，提高焊接一致性。焊片125设有避让孔，避让孔用于避让扁管13穿过，避让孔的数量与扁管13的数量相对设置，相邻避让孔之间的焊料部位于扁管13与扁管槽122b2配合位置的上方，以在焊料部融化后焊接扁管13与第二侧板122b。焊片125还设有避让槽，避让槽用于避让阻隔部122b1。As shown in FIG6 , the second side plate 122b is provided with a plurality of fixing parts 122b3, and the second side plate 122b is also provided with a flat tube groove 122b2, and the flat tube 13 passes through the second side plate 122b along the flat tube groove 122b2. The fixing part 122b3 can fix the welding piece 125 for welding the flat tube 13 and the flat tube groove 122b2, and the fixing part 122b3 is a riveted protrusion evenly distributed on the second side plate 122b. The welding piece 125 is provided with a plurality of fixing holes that cooperate with the fixing part 122b3. Through the cooperation between the fixing holes and the fixing part 122b3, the welding piece 125 is arranged on the second side plate 122b, which is convenient for assembly and improves welding consistency. The welding piece 125 is provided with avoidance holes, which are used to avoid the flat tube 13 from passing through. The number of avoidance holes is set relative to the number of flat tubes 13. The soldering parts between adjacent avoidance holes are located above the matching position of the flat tube 13 and the flat tube groove 122b2, so that the flat tube 13 and the second side plate 122b are welded after the soldering parts are melted. The welding piece 125 is also provided with an avoidance groove, which is used to avoid the blocking part 122b1.

扁管槽122b2设有导向部，导向部能够导向扁管13插至扁管槽122b2。本实施例中，扁管槽122b2的靠近第一侧板121的一侧设有导向部，导向部对扁管13与扁管槽122b2的插接起导向作用，使扁管13能够快速插至扁管槽122b2。该导向部可以为斜面，朝靠近第一侧板121的方向，导向部使扁管槽122b2的槽口逐渐增大。焊片125融化后，该导向部还能够容纳多余焊料，保证扁管13与第二侧板122b焊接牢固性。The flat tube groove 122b2 is provided with a guide portion, which can guide the flat tube 13 to be inserted into the flat tube groove 122b2. In this embodiment, a guide portion is provided on one side of the flat tube groove 122b2 close to the first side plate 121, and the guide portion guides the insertion of the flat tube 13 and the flat tube groove 122b2, so that the flat tube 13 can be quickly inserted into the flat tube groove 122b2. The guide portion can be an inclined surface, and the guide portion gradually increases the notch of the flat tube groove 122b2 toward the direction close to the first side plate 121. After the welding piece 125 melts, the guide portion can also accommodate excess solder to ensure the welding firmness of the flat tube 13 and the second side plate 122b.

如图2和图3所示，右集流腔组件12还包括第三侧板126，第三侧板126位于第一腔体122远离第一侧板121的一侧，第三侧板126与第一腔体122中，一者设有第二连接柱，另一者这有第二连接孔，通过第二连接柱与第二连接孔配合，实现第三侧板126与第一腔体122连接。也就是说，先通过第二连接柱与第二连接孔的配合，将第三侧板126和第一腔体122的相对位置进行限定后，再对第三侧板126的边缘部与第一腔体122靠近第三侧板126一侧的边缘部焊接，减小第三侧板126与第一腔体122焊接前位置发生变动的风险。因第三侧板126与第一腔体122的焊接位置位于边缘，还可采用超声波等无损检测对第三侧板126与第一腔体122的焊接位置进行检测，提高冷凝器1的焊接合格率和密封可靠性。As shown in FIG. 2 and FIG. 3 , the right manifold assembly 12 further includes a third side plate 126, which is located on a side of the first cavity 122 away from the first side plate 121. One of the third side plate 126 and the first cavity 122 is provided with a second connecting column, and the other has a second connecting hole. The third side plate 126 is connected to the first cavity 122 by the cooperation of the second connecting column and the second connecting hole. That is to say, the relative position of the third side plate 126 and the first cavity 122 is first defined by the cooperation of the second connecting column and the second connecting hole, and then the edge of the third side plate 126 is welded to the edge of the first cavity 122 close to the third side plate 126, so as to reduce the risk of position change of the third side plate 126 and the first cavity 122 before welding. Since the welding position between the third side plate 126 and the first cavity 122 is located at the edge, ultrasonic and other non-destructive testing methods can be used to detect the welding position between the third side plate 126 and the first cavity 122 to improve the welding qualification rate and sealing reliability of the condenser 1.

本实施例中。上述各焊接过程为冷凝器1的各部件固定后一体过炉实现焊接，提高效率。In this embodiment, the above welding processes are to weld the components of the condenser 1 in a furnace after they are fixed, thereby improving the efficiency.

如图3和图5所示，在一些实施例中，第一腔体122还设有若干个支撑部122e，若干个支撑部122e的两端分别与第二侧板122b和第三侧板126连接。本实施例通过设置支撑部122e，提高第一腔体122的耐压强度，减小第一空腔122a泄漏的风险。As shown in Fig. 3 and Fig. 5, in some embodiments, the first cavity 122 is further provided with a plurality of supporting parts 122e, and the two ends of the plurality of supporting parts 122e are respectively connected to the second side plate 122b and the third side plate 126. In this embodiment, by providing the supporting parts 122e, the pressure resistance of the first cavity 122 is improved, and the risk of leakage of the first cavity 122a is reduced.

如图3和图5所示，在一些实施例中，第一腔体122设有限位部122d，限位部122d能够限制扁管13插至第一空腔122a的位置。本实施例中，限位部122d位于第二侧板122b远离第一侧板121的一侧，扁管13***第一空腔122a内的端部与限位部122d抵接，限制部能够限制各扁管13继续朝第一空腔122a内运动，以限制扁管13的端部插至第一空腔122a内的位置，避免扁管13的端部***第一空腔122a过长，影响扁管13的另一端与左集流腔组件11焊接效果。或者，避免扁管13的端部***第一空腔122a过短，影响扁管13与第二侧板122b焊接效果。As shown in FIG. 3 and FIG. 5 , in some embodiments, the first cavity 122 is provided with a limiting portion 122d, and the limiting portion 122d can limit the position of the flat tube 13 inserted into the first cavity 122a. In this embodiment, the limiting portion 122d is located on the side of the second side plate 122b away from the first side plate 121, and the end of the flat tube 13 inserted into the first cavity 122a abuts against the limiting portion 122d. The limiting portion can limit each flat tube 13 from continuing to move into the first cavity 122a, so as to limit the end of the flat tube 13 from being inserted into the first cavity 122a, and avoid the end of the flat tube 13 being inserted into the first cavity 122a too long, which affects the welding effect of the other end of the flat tube 13 and the left manifold assembly 11. Alternatively, avoid the end of the flat tube 13 being inserted into the first cavity 122a too short, which affects the welding effect of the flat tube 13 and the second side plate 122b.

如图2和图3所示，在一些实施例中，第一腔体122设有避让部122f，避让部122f靠近第一侧板121与第二侧板122b的焊接位置设置，使第一腔体122的外表面形成阶梯结构。通过设置避让部122f，无需对冷凝器1的结构进行破坏，即可使第一侧板121与第二侧板122b的焊接位置可以实现超声波等无损检测，提高冷凝器1的焊接合格率和密封可靠性。As shown in Fig. 2 and Fig. 3, in some embodiments, the first cavity 122 is provided with a relief portion 122f, and the relief portion 122f is arranged close to the welding position of the first side plate 121 and the second side plate 122b, so that the outer surface of the first cavity 122 forms a stepped structure. By providing the relief portion 122f, the welding position of the first side plate 121 and the second side plate 122b can be subjected to non-destructive testing such as ultrasonic testing without destroying the structure of the condenser 1, thereby improving the welding qualification rate and sealing reliability of the condenser 1.

如图3所示，冷凝器1还包括滤网14，滤网14由高密度金属丝编织而成，如不锈钢滤网14。该滤网14安装于第一空腔122a内，与扁管13插至第一空腔122a内的端口相对设置，起到过滤杂质作用，避免大颗粒杂质参与循环，进入泵或冷板铲齿等其他部件造成影响，提升***使用寿命。As shown in FIG3 , the condenser 1 further includes a filter 14, which is woven from high-density metal wires, such as a stainless steel filter 14. The filter 14 is installed in the first cavity 122a, and is arranged opposite to the port where the flat tube 13 is inserted into the first cavity 122a, so as to filter impurities, prevent large particles from participating in the circulation, and enter other components such as the pump or the cold plate scraper teeth to cause an impact, thereby improving the service life of the system.

如图8所示，左集流腔组件11设有第二腔体112，冷凝器1还包括气液分离管15，气液分离管15的一端与出液口111连接，另一端延伸至第二腔体112内液面以下位置。当进液口128输入的冷却液混有气体，混有气体的冷却液沿扁管13流至第二腔体112时，由于气液分离管15的一端在第二腔体112内液面以下的位置，气体会自动上浮，实现气液分离，因气液分离管15的另一端与出液口111连接，气液不能沿气液分离管15流动至出液口111，以及沿出液口111流动至***内，避免气液混输加剧***腐蚀、降低换热效率。 As shown in Fig. 8, the left manifold assembly 11 is provided with a second cavity 112, and the condenser 1 further comprises a gas-liquid separation tube 15, one end of which is connected to the liquid outlet 111, and the other end of which extends to a position below the liquid level in the second cavity 112. When the coolant inputted from the liquid inlet 128 is mixed with gas, and the coolant mixed with gas flows to the second cavity 112 along the flat tube 13, since one end of the gas-liquid separation tube 15 is below the liquid level in the second cavity 112, the gas will automatically float up to achieve gas-liquid separation, and since the other end of the gas-liquid separation tube 15 is connected to the liquid outlet 111, the gas and liquid cannot flow along the gas-liquid separation tube 15 to the liquid outlet 111, and flow along the liquid outlet 111 into the system, so as to avoid gas-liquid mixing, which aggravates system corrosion and reduces heat exchange efficiency.

如图9所示，冷凝器1还包括储液腔16，储液腔16的两端分别连通第一腔体122和第二腔体112，储液腔16可以设置冷凝器1的顶部。储液腔16用于存储冷却液，在冷凝器1内循环冷却液减少时，可通过储液腔16补入。储液腔16靠近第一腔体122的一侧设有挡板161，挡板161能够阻挡部分冷却液沿第一腔体122流入储液腔16内。因储液腔16的流道较大，通过设置挡板161，对储液腔16进行减流，以使大部分冷却液流向扁管13。As shown in FIG9 , the condenser 1 further includes a liquid storage chamber 16, the two ends of which are connected to the first cavity 122 and the second cavity 112 respectively, and the liquid storage chamber 16 can be provided at the top of the condenser 1. The liquid storage chamber 16 is used to store coolant, and when the circulating coolant in the condenser 1 is reduced, it can be replenished through the liquid storage chamber 16. A baffle 161 is provided on one side of the liquid storage chamber 16 close to the first cavity 122, and the baffle 161 can block part of the coolant from flowing into the liquid storage chamber 16 along the first cavity 122. Because the flow channel of the liquid storage chamber 16 is relatively large, the baffle 161 is provided to reduce the flow of the liquid storage chamber 16, so that most of the coolant flows to the flat tube 13.

在一些实施例中，冷凝器1还包括多个翅片17，翅片17设置在相邻扁管13之间，通过设置翅片17增大冷凝器1的散热面积，提高散热效率。In some embodiments, the condenser 1 further includes a plurality of fins 17 , and the fins 17 are disposed between adjacent flat tubes 13 . The fins 17 are disposed to increase the heat dissipation area of the condenser 1 and improve the heat dissipation efficiency.

如图10所示，在一些实施例中，左集流腔组件11与右集流腔组件12可以为一体成型，形成双层空腔，使双层空腔形成的双层侧板也为一体成型，双层侧板设有扁管通道121a。扁管13沿扁管通道121a依次穿过双层侧板，与双层侧板形成双层焊缝，进而形成双层密封结构。在第一空腔122a的焊缝发生泄漏时，第二空腔122c能够还能够阻挡冷却液外漏，提高冷凝器1工作稳定性。本实施例中左集流腔组件11与右集流腔组件12采用一体成型工艺制作，提高生产效率，降低生产成本。采用一体成型制作便于设置第二空腔122c，通过设置第二空腔122c减小第二层焊缝失效带来的散热性能损失。As shown in FIG. 10 , in some embodiments, the left manifold assembly 11 and the right manifold assembly 12 can be integrally formed to form a double-layer cavity, so that the double-layer side plate formed by the double-layer cavity is also integrally formed, and the double-layer side plate is provided with a flat tube channel 121a. The flat tube 13 passes through the double-layer side plate in sequence along the flat tube channel 121a, and forms a double-layer weld with the double-layer side plate, thereby forming a double-layer sealing structure. When the weld of the first cavity 122a leaks, the second cavity 122c can also prevent the coolant from leaking out, thereby improving the working stability of the condenser 1. In this embodiment, the left manifold assembly 11 and the right manifold assembly 12 are manufactured using an integral molding process to improve production efficiency and reduce production costs. The use of integral molding facilitates the setting of the second cavity 122c, and the heat dissipation performance loss caused by the failure of the second layer of welds is reduced by setting the second cavity 122c.

如图11所示，本实施例还提供了一种散热***，散热***包括处理模块2、冷却板3、冷凝器1、循环泵4和风扇。冷却板3靠近处理模块2设置，冷却板3与冷凝器1和循环泵4通过管路5相连通形成散热回路，风扇用于对冷凝器1散热。循环泵4能够带动冷却板3内吸热的冷却液流至冷凝器1，并带动经冷凝器1散热的冷却液流回至冷却板3。As shown in FIG11 , this embodiment further provides a heat dissipation system, which includes a processing module 2, a cooling plate 3, a condenser 1, a circulating pump 4 and a fan. The cooling plate 3 is arranged close to the processing module 2, and the cooling plate 3 is connected with the condenser 1 and the circulating pump 4 through a pipeline 5 to form a heat dissipation circuit, and the fan is used to dissipate heat from the condenser 1. The circulating pump 4 can drive the cooling liquid that absorbs heat in the cooling plate 3 to flow to the condenser 1, and drive the cooling liquid that dissipates heat through the condenser 1 to flow back to the cooling plate 3.

本实施例中，处理模块2可以为数据中心服务器、车载空调换热***中等器件中的需散热部件。冷却板3设置在处理模块2一侧，冷却板3设有空腔，空腔内盛有冷却液，通过冷却液吸收处理模块2产生的热量，实现对处理模块2散热。循环泵4用于散热回路中的冷却液进行循环，使吸收热量的冷却液沿管路5流出冷却板3的空腔，并沿冷凝器1的进液口128流向各扁管13，风扇对扁管13吹冷风，使各扁管13内的冷却液散热，散热后的冷却液沿冷凝器1的出液口111流出，并沿管路5流回冷却板3的空腔内，继续吸收处理模块2散出的热量，以保证处理模块2正常工作。In this embodiment, the processing module 2 can be a component that needs heat dissipation in a data center server, a vehicle air conditioning heat exchange system, and the like. The cooling plate 3 is arranged on one side of the processing module 2, and the cooling plate 3 is provided with a cavity, and the cavity contains a coolant, and the coolant absorbs the heat generated by the processing module 2 to achieve heat dissipation of the processing module 2. The circulation pump 4 is used to circulate the coolant in the heat dissipation circuit, so that the coolant that absorbs the heat flows out of the cavity of the cooling plate 3 along the pipeline 5, and flows to each flat tube 13 along the liquid inlet 128 of the condenser 1. The fan blows cold air to the flat tube 13, so that the coolant in each flat tube 13 dissipates heat. The coolant after heat dissipation flows out along the liquid outlet 111 of the condenser 1, and flows back to the cavity of the cooling plate 3 along the pipeline 5, and continues to absorb the heat dissipated by the processing module 2 to ensure the normal operation of the processing module 2.
