本发明涉及热交换领域，尤其涉及水、油、CO 2、空气、制冷剂等同类及非同类介质之间进行热交换的装置。 The invention relates to the field of heat exchange, in particular to a device for heat exchange between homogeneous and non-homogeneous media such as water, oil, CO 2 , air, refrigerant and the like.
背景技术Background technique
换热器(heat exchanger)，是将热流体的部分热量传递给冷流体的设备，又称热交换器。换热器在家电领域，或是化工、石油、动力、食品及其它许多工业生产中占有重要地位，可作为加热器、冷却器、冷凝器、蒸发器和再沸器等使用。A heat exchanger (heat exchanger) is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. The heat exchanger occupies an important position in the field of home appliances, or chemical, petroleum, power, food and many other industrial productions, and can be used as heaters, coolers, condensers, evaporators, and reboilers.
在我国，北方冬季室内采暖装置成为家庭的标准配置，南方冬季室内采暖也日益得到重视并逐渐进入千家万户。随着国家环保要求的提高，提供60-90℃循环热水的煤锅炉会被要求逐步退出，提供40-60℃循环热水的空气能、地源热泵及风冷热泵机组因为技术成熟、高效节能、清洁环保，使用数量不断增多，应用范围逐步扩大。所以，传统高水温暖气片已经不能满足市场需求。In China, indoor heating in winter in the north has become the standard configuration for households, and indoor heating in winter in the south has also been paid more and more attention and gradually entered thousands of households. With the improvement of national environmental protection requirements, coal boilers that provide 60-90 ° C circulating hot water will be required to gradually withdraw. Air energy, ground source heat pumps and air-cooled heat pump units that provide 40-60 ° C circulating hot water are mature and efficient Energy saving, clean and environmental protection, the number of uses is increasing, and the scope of application is gradually expanding. Therefore, traditional high-water warm air tablets can no longer meet market demand.
申请号201721897724.6的中国实用新型公开了一种板式带翅片散热器，包括两平行设置的进出水管以及并排设置在两进出水管之间的两排散热管，散热管为金属扁管，且该金属扁管的轴向两端与进出水管连接，两排散热管分别设置在进出水管的前后两侧。散热管的内侧面焊接有散热翅片，该散热器的优点是散热面积大，增强了散热效果。由于承压原因，该散热器需要采用壁厚较厚的管材，其散热管扁管被加工成型，且外部焊点较多，通常需要电泳喷塑处理，降低了换热效果，增加了漏水概率。所以，散热器整体重量大，成本高，换热效果不够理想。The Chinese utility model with the application number 201721897724.6 discloses a plate-type finned radiator, which includes two parallel water inlet and outlet pipes and two rows of heat dissipation pipes arranged side by side between the two water inlet and outlet pipes. The heat dissipation pipe is a metal flat pipe, and the metal The axial ends of the flat tube are connected to the water inlet and outlet pipes, and the two rows of heat dissipation pipes are respectively arranged on the front and back sides of the water inlet and outlet pipes. The inner side of the heat dissipation tube is welded with heat dissipation fins. The advantage of the heat dissipator is that the heat dissipation area is large, and the heat dissipation effect is enhanced. Due to the pressure-bearing reasons, the radiator needs to use thick-walled tubes, the heat-radiating flat tubes are processed and formed, and there are many external solder joints, usually requiring electrophoresis spray treatment, which reduces the heat exchange effect and increases the probability of water leakage . Therefore, the overall weight of the radiator is high, the cost is high, and the heat exchange effect is not ideal.

Composite fins on the surface of the heat transport device enhance the heat transfer effect. The patented device requires a combination of multiple plate-type heat transport devices, many welding procedures, complicated processes, and high costs. The plate type heat transport device described in this patent and its designed micro-channel structure can usually only be obtained by extruding aluminum material, and the aluminum profile micro-channel has a large fouling coefficient, which is very unsuitable for hot water media, especially the northern water quality. Be applicable.
目前暖气片换热器普遍存在下面一个或多个问题，1)采用较厚材质的金属件，重量大，成本高。2)焊接工序较多或组装工序复杂，工艺性不好，后续表面处理影响换热效果。3)换热介质分配不均匀，部分流道直径大，存在温度分层现象，热交换效率低。4)适用于60-90度高水温换热，但对40-60度低水温制热效果差。5)换热器内部储水量多，增加了散热器总重量、降低了热交换的响应速度，使热量有所损失。At present, one or more of the following problems generally exist in radiator heat exchangers. 1) Metal parts with thicker materials are used, which are heavy and costly. 2) There are many welding procedures or complicated assembly procedures, and the manufacturability is not good. The subsequent surface treatment affects the heat exchange effect. 3) The heat exchange medium is unevenly distributed, part of the flow channel diameter is large, there is a phenomenon of temperature stratification, and the heat exchange efficiency is low. 4) It is suitable for heat exchange at high water temperature of 60-90 degrees, but poor heating effect at low water temperature of 40-60 degrees. 5) There is a large amount of water stored in the heat exchanger, which increases the total weight of the radiator, reduces the response speed of heat exchange, and causes heat loss.
为了解决上述技术问题，本次专利申请以申请号为“2018113840227”的中国发明专利申请文本作为优先权文本，所得到的技术方案能够解决上述技术问题，保证介质充分利用换热面，利于换热效果的最大化。In order to solve the above technical problems, this patent application takes the Chinese invention patent application with the application number "2018113840227" as the priority text.

The micro-pass plate is composed of two plates (the front plate 1 and the back plate 2 are shown in the figure); specifically, the periphery of the two plates and the convex joint in the middle are tightly combined into a whole The brazing method is often used for the connection method, and the convex joints 8 on the two plates are combined into a tight fixing point 81 by brazing. The tight fixing points 81 are relatively evenly distributed on the inner side of the plates. The tight fixing points 81 are mainly used for connecting and fixing between the two plates, which can ensure the bearing strength of the micro-pass plate. In this embodiment, the plates can be processed first, and then the two plates can be combined into a micro-pass plate by welding or the like. In addition to the medium inlet and outlet, the combined micro-pass plate is sealed around. The convex joint 8 in the middle is compounded as a tight joint 81. The surrounding sealing layer 9 and many tight joints 81 ensure that the micro-pass board can be made of thin plate. The pressure bearing capacity meets the design requirements. The integral molding and integral welding technology greatly simplify the production process and improve the quality and reliability. In addition, on the basis of the connection strength guaranteed by this connection structure, a thin plate or ultra-thin plate can be used as a plate. The micro-pass plate formed by the thin plate or ultra-thin plate has fast heat transfer speed, high heat exchange efficiency, and simple process. The advantages of reliable quality and low cost.

The length of the medium path formed by any tiny heat exchange channel 5 passing through the medium inlet 3 to the medium outlet 7 is substantially equal. In this way, the medium resistance in each medium path is balanced, which further ensures that the medium can be evenly distributed in the heat exchanger, making full use of the heat exchange surface, which is conducive to maximizing the heat exchange effect. In this solution, the outer shapes of the two plates are not limited, including rectangular plates horizontally and vertically, with or without arc-shaped polygonal horizontally and vertically, etc. should be understood in this solution. In this solution, there are no restrictions on the configuration of the distribution channel 4 and the collection channel 6, so a series of programs including up and down, down and up, left and right, or right and left and out should be understood in this plan in. In addition, in the specific implementation of this solution, the positions of the media inlet 3 and the media outlet 7 are limited. However, considering the above-mentioned different arrangement of the distribution channel 4 and the collection channel 6, the upper and lower sides of the two plates, The configuration of media inlet 3 and media outlet 7 on the left and right sides or other positions should be understood in this solution; the media inlet 3 on both sides of the distribution channel 4 shown in the figure, and the media outlet 7 on both sides of the collection channel 6 are In order to improve the adaptability of the product, one of the medium inlet 3 and the medium outlet 7 can be selected in actual use, and the medium inlet 3 and the medium outlet 7 arranged diagonally need to be selected to ensure that the path lengths of the micro heat exchange channels 5 are substantially equal.
基于上述技术方案，介质进口、分配通道、微小换热通道、收集通道和介质出口能够分别成型在任一板片上，并与另一板片对接构成微通板；或者是介质进口、分配通道、微小换热通道、收集通道和介质出口能够成型在两片板片，并由两片板片对接构成微通板；微通板的两个外侧换热面分别是平面或凹凸面。如图中所示，所述微通板采用前板片1和后板片2两块板片复合成型，两块板片的对接面上均设有分配流通槽41、42、收集流通槽61、62和多个微小介质流通槽51、52。两块板片的分配通道41、42对接构成分配通道4，收集通道61、62对接构成收集通道6，微小介质流通槽51、52或对接或独立构成上述微小换热通道5。分配通道4与众多微小换热通道5的入口端连通，收集通道6与众多微小换热通道5的出口端连通，分配通道4的端部设有介质进口3，收集通道6的端部设有介质出口7。介质进口3、介质出口7可以呈对角配置，也可以呈同侧配置。在此优选方案中，单片板片上的分配流通槽、微小介质流通槽和收集流通槽通过冲压一体成型得到；两片板片对接时构成完整的分配通道、微小换热通道和收集通道。另外，所述的微通板的两个外侧换热面可以分别是平面或凹凸面。在其中一种优选方案中，单片板片的内侧冲压出分配通道、微小换热通道和收集通道时，在板片外侧壁上形成凸起，外侧相邻两条凸起之间构成凹槽，外侧换热表面凹凸相间增加换热面积。内侧流道与外侧凹凸换热面采用一体冲压工艺，同时在构成板片对接面上的介质流通槽时，在板片的外侧形成凹凸面，简化加工工艺步骤，增加换热面积，提升换热效果。同时，可将所述的板片选择为粗糙表面，进一步提升介质换热效果。Based on the above technical solutions, the media inlet, distribution channel, micro heat exchange channel, collection channel and media outlet can be formed on any plate respectively, and connected with another plate to form a micro-pass plate; or the medium inlet, distribution channel, micro The heat exchange channel, the collection channel and the medium outlet can be formed on two plates, and the two plates are connected to form a micro-pass plate; the two outer heat-exchange surfaces of the micro-pass plate are plane or concave-convex surfaces, respectively. As shown in the figure, the micro-pass plate is formed by compounding two plates of the front plate 1 and the rear plate 2, and the distribution surfaces of the two plates are distributed distribution grooves 41 and 42 and the collection flow groove 61 , 62 and a plurality of tiny medium circulation grooves 51, 52. The distribution channels 41 and 42 of the two plates are connected to form a distribution channel 4, the collection channels 61 and 62 are connected to form a collection channel 6, and the micro-medium circulation grooves 51 and 52 are connected or independently formed to form the above-mentioned micro heat exchange channels 5. The distribution channel 4 communicates with the inlet end of many micro heat exchange channels 5, the collection channel 6 communicates with the outlet end of many micro heat exchange channels 5, the end of the distribution channel 4 is provided with a medium inlet 3, and the end of the collection channel 6 is provided with Media outlet 7. The medium inlet 3 and the medium outlet 7 may be arranged diagonally or on the same side. In this preferred solution, the distribution circulation groove, the minute medium circulation groove and the collection circulation groove on the single plate are formed by stamping; when the two plates are butted, a complete distribution channel, a small heat exchange channel and a collection channel are formed. In addition, the two outer heat exchange surfaces of the micro-pass plate may be flat or uneven surfaces, respectively. In one of the preferred solutions, when the distribution channel, the micro heat exchange channel and the collection channel are punched out on the inner side of the single plate, a protrusion is formed on the outer side wall of the plate, and a groove is formed between two adjacent protrusions on the outer side , The heat exchange surface on the outer heat exchange surface is uneven to increase the heat exchange area. The inner flow channel and the outer concave and convex heat exchange surface adopt an integrated stamping process. At the same time, when forming the medium circulation groove on the butt surface of the plate, a concave and convex surface is formed on the outside of the plate, simplifying the processing steps, increasing the heat exchange area, and improving heat transfer effect. At the same time, the plate can be selected as a rough surface to further enhance the heat exchange effect of the medium.
上述微通板由前板片1和后板片2复合成型，一般采用金属材质制成也可选择高导热率的非金属材料；在选用金属材料时，可选用不锈钢、碳钢、铜及合金铜、合金铝、合金钛等材料。之所以称为微通板，是因为其二个明显特征：1)由薄板制成，2)板内微小换热通道5为微小的通道，一般直径在0.5～20mm。此处所指的微小通道是相对而言，是指相对于分配通道1、收集通道2的口径，微小换热通道5的口径可称为微小通道。并且上述微通板的流通介质包括但不限于水、油、CO 2、空气、制冷剂，不同介质的粘稠度不同，因此与其相适 应的通道直径大小也不同。 The above-mentioned micro-pass plate is formed by compounding the front plate 1 and the rear plate 2. Generally, it is made of metal materials and non-metallic materials with high thermal conductivity can also be selected; when selecting metal materials, stainless steel, carbon steel, copper and alloys can be selected Copper, aluminum alloy, titanium alloy and other materials. The reason why it is called a micro-pass plate is because of its two obvious characteristics: 1) made of thin plate, 2) the small heat exchange channel 5 in the plate is a small channel, generally 0.5 ~ 20mm in diameter. The micro-channel referred to here is relatively speaking, and refers to the caliber of the distribution channel 1 and the collection channel 2, and the caliber of the micro-heat exchange channel 5 may be referred to as a micro-channel. In addition, the flow medium of the micro-pass plate includes but is not limited to water, oil, CO 2 , air, and refrigerant. Different media have different viscosities, so the diameter of the channel corresponding to them is also different.
基于上述方案所得到的微通板，其内置的多条微小换热通道5中，至少有两条微小换热通道相互交错。以使微小换热通道5内的流体介质产生紊流和湍流，由于介质产生了紊流和湍流，从而使介质的温度分层被打乱，换热效果大大提升。并根据以上原理，对于微通板的改进提供多种实施方案，具体如下：In the micro-pass plate obtained based on the above solution, among the plurality of micro heat exchange channels 5 built therein, at least two micro heat exchange channels are interleaved with each other. In order to cause turbulent flow and turbulent flow in the fluid medium in the micro heat exchange channel 5, the turbulent flow and turbulent flow are generated by the medium, so that the temperature stratification of the medium is disrupted, and the heat exchange effect is greatly improved. According to the above principles, various implementation solutions are provided for the improvement of the micro-pass board, as follows:
(一)，第一种方案中，前板片和后板片上均设有相对应的凸起贴合处和微小介质流通槽，凸起贴合处作为微小介质流通槽之间的隔断，能够对微小换热通道5内的介质形成打散作用，被打散的介质分配到相邻的二个微小换热通道内，如此反复。介质流动过程中被不断打散又不断汇合，类似河道里的桥墩使水流形成紊流和湍流。微小换热通道5和紧密固定点81共同作用，使介质在二片板片内侧形成水帘状均匀分布。在薄板内侧水帘状均匀分布的介质，与普通换热器相比，大大提升了与外界的换热效果。前板片和后板片上的凸起贴合处对接后，复合后的对接点呈类似矩阵状布置。其中一种方案(图略)，所述微小换热通道间凸起的贴合处为圆形或椭圆形，位于对接点之间的介质流道呈孔雀屏状。又如图1所示，所述微小换热通道间凸起的贴合处为多边形，位于对接点之间的介质流道呈蜂窝形状。该技术方案代表特征是单片板片上的微小换热通道已经构成交错网状，即使与另一平面板片复合，其介质流动也可以形成紊流。(1) In the first scheme, the front plate and the rear plate are provided with corresponding convex lamination places and micro-medium circulation grooves. The convex lamination places are used as partitions between the micro-medium circulation grooves. It breaks the medium in the micro heat exchange channel 5 and the broken medium is distributed to the two adjacent micro heat exchange channels, and so on. During the flow of the medium, it is broken up and merged continuously, similar to the pier in the river channel, which makes the water flow form turbulence and turbulence. The tiny heat exchange channel 5 and the tight fixing point 81 work together to make the medium form a water curtain and distribute evenly inside the two plates. Compared with the ordinary heat exchanger, the medium distributed uniformly in the shape of water curtain inside the thin plate greatly improves the heat exchange effect with the outside world. After the butt joints on the front panel and the rear panel are butted, the compounded butt joints are arranged like a matrix. In one of the schemes (figure omitted), the convex joints between the tiny heat exchange channels are circular or elliptical, and the medium flow channel between the butt joints is peacock-shaped. As shown in FIG. 1 again, the convex joints between the micro heat exchange channels are polygonal, and the medium flow channels between the butt joints have a honeycomb shape. The representative feature of this technical solution is that the tiny heat exchange channels on a single plate have formed a staggered network, even if it is combined with another flat plate, its medium flow can also form turbulent flow.
(二)，第二种方案中，单块板片对接面上的多个介质流通槽之间不产生交错。两块板片复合连接时，两块板片上的介质流通槽对角交错构成微小换热通道。如图中所体现，对角交错是指两条介质流通槽采用对角线交错方式进行交叉。在进一步地优选方案中，一块板片上的一条介质流通槽，与另一块板片上的两条及以上的介质流通槽相交错。该技术方案中，两块板片上的介质流通槽对角交错，其中单个介质流通槽的截面可以呈现为半圆形，而两个介质流通槽的交汇点则呈现两个半圆形斜角对接构成的菱形腔53，其空间相对介质流通槽较大，两条介质流通槽在此汇流。由此同时，介质流通槽为内凹槽，则相邻两条介质流通凹槽之间的凸起区域为窄平面，两块板片对接时，窄平面也呈对角交错构成上述凸起面的贴合处8(焊接点)，前板片和后板片凸起的贴合处8对接(焊接)后形成紧密固定点81，且该紧密固定点81与菱形腔四周(上下方向和左右方向)均间隔设置，其产生的效果是两条介质流通槽在菱形腔内汇流，而后又被凸起的紧密固定点81分配到相邻的二个微小换热通道5内，产生汇流和分流交替，提升紊流效果。上述方案中，介质流通槽呈多段折线形(如图中所示的W形)或波纹形，在介质流通槽选择为多段折线形应当考虑限制多段折线的折角度数，其一方面影响着微小换热通道5中的介质流通阻力，另一方面可减少板片左右两侧端(非分配通道和收集通道端)上所形成的流体换热弱化区面积，即此处内部微小换热通道5的流道阻力及流道 数量与中间部位的流道相比略有不同。一般实施时需考虑合理设置介质流通通道的折角度数。而当介质流通槽选择为波纹形时，应当限定波纹的振幅与波长。该方案相比于方案(一)的特点在于，此方案中的单片板片上设置的介质流通槽是不产生交错的，只有当两片单片板片复合连接时，其所构成的微小换热通道才形成相互交错。(2) In the second solution, there is no interleaving between the multiple medium circulation grooves on the butt joint surface of a single plate. When the two plates are connected together, the medium circulation grooves on the two plates are diagonally staggered to form a tiny heat exchange channel. As shown in the figure, diagonal interleaving means that the two medium circulation channels intersect diagonally. In a further preferred solution, one medium circulation groove on one plate is interleaved with two or more medium circulation grooves on the other plate. In this technical solution, the media flow channels on the two plates are diagonally staggered, where the cross section of a single media flow channel can appear semicircular, and the intersection of the two media flow channels presents two semicircular oblique angles butt The formed diamond-shaped cavity 53 has a larger space relative to the medium circulation groove, and the two medium circulation grooves converge here. At the same time, the medium circulation groove is an inner groove, and the convex area between two adjacent medium circulation grooves is a narrow plane. When the two plates are butted, the narrow planes also diagonally form the convex surface The joint 8 (welding point) of the front panel and the rear panel convex joint 8 is welded (welded) to form a tight fixing point 81, and the tight fixing point 81 and the diamond-shaped cavity around (up and down direction and left and right (Direction) are evenly spaced, the effect of which is that the two medium circulation grooves converge in the diamond-shaped cavity, and then are distributed to the adjacent two tiny heat exchange channels 5 by the raised tight fixed point 81, generating confluence and shunt Alternate to enhance the effect of turbulence. In the above scheme, the medium circulation groove is multi-section fold line (W shape as shown in the figure) or corrugated shape. When the medium circulation groove is selected as multi-section fold line shape, consideration should be given to limiting the number of fold angles of the multi-section fold line. The medium flow resistance in the heat channel 5 on the other hand can reduce the area of the fluid heat exchange weakening area formed on the left and right sides of the plate (non-distribution channel and collection channel end), that is, the internal small heat exchange channel 5 The flow channel resistance and the number of flow channels are slightly different from those in the middle. In general implementation, it is necessary to consider the reasonable setting of the number of fold angles of the medium circulation channel. When the medium circulation groove is selected to be corrugated, the amplitude and wavelength of the corrugation should be limited. The feature of this solution compared to solution (1) is that the medium circulation grooves provided on the single plate in this solution do not create staggering. Only when two single plates are compositely connected, the small change The hot aisles are only interlaced.
本实施方案涉及一种微通板，该微通板采用一体成型并复合的方案，简化工艺、提升质量和可靠性。微通板内部的内侧介质流道由分配通道、收集通道以及网状交叉的微小换热通道组成，微小换热通道将流道内介质打散形成紊流和湍流。由介质进口至介质出口的多条介质通道的路径长度相近，成网状交错均匀分布于整个板面的微小换热通道进一步保证介质充分利用换热面，利于换热效果的最大化。This embodiment relates to a micro-pass board, which adopts an integrated molding and compound scheme to simplify the process and improve quality and reliability. The inner media flow channel inside the micro-pass plate is composed of a distribution channel, a collection channel and a network of tiny heat exchange channels, which disperse the medium in the channel to form turbulence and turbulence. The path lengths of the multiple medium channels from the medium inlet to the medium outlet are similar, and the small heat exchange channels that are staggered in a network and evenly distributed on the entire board surface further ensure that the medium fully utilizes the heat exchange surface, which is conducive to maximizing the heat exchange effect.
在上述所需解决的技术问题之上，该微通板还具有如下特点；On top of the technical problems to be solved above, the micro-pass board also has the following characteristics;
1，在单片板片的内侧机械加工分配通道、微小换热通道、收集通道凹槽，在板片外侧壁上形成凸起，外侧相邻两条凸起之间构成凹槽，外侧凹凸相间增加外侧换热面积，大幅提升了与外界的换热效果。1. Machine the distribution channels, micro heat exchange channels, and collection channel grooves on the inside of a single plate to form protrusions on the outer wall of the plate, and form grooves between the two adjacent protrusions on the outside, and the outer sides are concave and convex Increasing the heat exchange area on the outside greatly improves the heat exchange effect with the outside world.
2，微通板的二片板片采用薄板或超薄板，外部无焊接点，有色金属的微通板无须后期电泳喷塑等处理，不仅大大提高了传热速度和换热效果，而且节能环保、降低材料消耗。2. The two plates of the micro-pass plate are thin plates or ultra-thin plates, and there are no solder joints on the outside. The non-ferrous metal micro-pass plates do not require post-electrophoresis spray molding and other treatments, which not only greatly improves the heat transfer speed and heat exchange effect, but also saves energy Environmental protection, reduce material consumption.
3，微通板具有超薄、体积小、储水量少、重量轻、工艺简单、质量可靠、节能环保、外观美、热交换效率高、成本低、特别适用于40-60度低温水换热等优点。3. The micro-pass board has ultra-thin, small size, low water storage, light weight, simple process, reliable quality, energy saving and environmental protection, beautiful appearance, high heat exchange efficiency, low cost, and is particularly suitable for 40-60 degrees low temperature water heat exchange Etc.
实施例2：Example 2:
上述实施例1所得到的一种新型微通板与室内空气的传热速度快、换热效果极佳。在上述背景下，申请人发现虽然微通板内部的第一介质得到充分紊流，但微通板外侧的第二介质换热效率还有很大的提升空间，因此在对其基础上进行改进，得到实施例2。如图7～11所示，实施例2对于第二介质换热效率进一步提升；具体来说是在所述两块板片中至少有一块板片的外侧换热面上设有导热部件，导热部件的作用是用于增加第二介质换热面积。在具体的可实施方案中，导热部件是由板片上一体冲压得到的导热凸起21，可以是由任一板片上一体冲压得到的导热凸起，或者是二片板片上均一体冲压得到的导热凸起，如图中所示，是在后板片2上冲压得到导热凸起21；导热凸起21与另一板片之间构成用于供第二介质经过的外通道；所述外通道的通道两端分别指向分配通道和收集通道。所述外通道的区域内，两块板片密封连接以使外通道与微小换热通道相互独立，即需要沿外通道的区域外沿将两块板片密封连接，防止微小换热通道内的第一介质泄露。在该方案中，导热凸起21所构成的外通道是用于供第二介质经过，一方面导热凸起21所形成的外通道侧壁增加了第二介质的换热效率；另一方面由于上述换热效率提升，外通道内的第二介质的自然对流更强，流通效率更加，使该 区域的换热效率进一步提升。另外，进一步的实施方案是，在所述板片上一体冲压得到多个导热凸起21，微小换热通道设置于相邻两个导热凸起21之间，以及最外侧导热凸起21与板片边缘之间的微通板内部。The novel micro-pass plate obtained in the above example 1 has a fast heat transfer rate with indoor air and excellent heat exchange effect. Under the above background, the applicant found that although the first medium inside the micro-pass plate is sufficiently turbulent, there is still much room for improvement in the heat exchange efficiency of the second medium outside the micro-pass plate, so it is improved on the basis of it ， Get Example 2. As shown in FIGS. 7-11, the heat transfer efficiency of the second medium is further improved in Example 2; specifically, at least one of the two plates is provided with a heat conducting component on the outer heat exchange surface, The function of the component is to increase the heat exchange area of the second medium. In a specific possible embodiment, the thermally conductive component is a thermally conductive protrusion 21 obtained by integrally stamping on a plate, which may be a thermally conductive protrusion obtained by integrally pressing on any plate, or a thermal conduction obtained by integrally stamping on both plates The projection, as shown in the figure, is stamped on the rear plate 2 to obtain a thermally conductive projection 21; an external channel for the second medium to pass through is formed between the thermally conductive projection 21 and another plate; the external channel The two ends of the channel point to the distribution channel and the collection channel respectively. In the area of the outer channel, the two plates are connected in a sealed manner to make the outer channel and the micro heat exchange channel independent of each other, that is, the two plates need to be hermetically connected along the outer edge of the area of the outer channel to prevent the The first medium leaked. In this solution, the outer channel formed by the heat-conducting protrusion 21 is used for the second medium to pass through. On the one hand, the outer channel side wall formed by the heat-conducting protrusion 21 increases the heat exchange efficiency of the second medium; The above heat exchange efficiency is improved, the natural convection of the second medium in the outer channel is stronger, and the circulation efficiency is more, which further improves the heat exchange efficiency in this area. In addition, in a further embodiment, a plurality of thermally conductive protrusions 21 are integrally stamped on the plate, the micro heat exchange channel is provided between two adjacent thermally conductive protrusions 21, and the outermost thermally conductive protrusion 21 and the plate Inside the micro-pass plate between the edges.
实施例3：Example 3:
本实施例与实施例2类似，均是实施例1的技术方案中第二介质换热效率还有很大提升空间的基础上改良得到，并采用与实施例2相同的原理。本实施例也涉及一种微通板，该微通板与实施例2中所提到的微通板的区别仅在于：本方案中，所述导热部件是外接于板片外侧换热面上的导热凸起21，导热凸起21与其连接的板片之间构成用于供第二介质经过的外通道；所述外通道的通道两端分别指向分配通道和收集通道。该方案中的导热凸起21外接在外侧换热面上，而实施例1中的导热凸起21是由板片一体冲压得到的。因此在本实施例中，两个外侧换热面之间构成整个微小换热通道，并且导热凸起21能够采用焊接等固定方式连接于板片上。该方案具有实施例1方案中所提到微通板的所有优势。This embodiment is similar to Embodiment 2, and is based on the improvement of the heat exchange efficiency of the second medium in the technical solution of Embodiment 1 on the basis that there is much room for improvement, and uses the same principles as in Embodiment 2. This embodiment also relates to a micro-pass plate. The difference between the micro-pass plate and the micro-pass plate mentioned in Embodiment 2 is only that: in this solution, the heat conducting component is externally connected to the heat exchange surface outside the plate The heat conduction protrusion 21 of the heat conduction protrusion 21 and the connected plate form an external channel for the second medium to pass through; the two ends of the channel of the external channel point to the distribution channel and the collection channel respectively. In this solution, the heat-conducting protrusion 21 is circumscribed on the outer heat exchange surface, while the heat-conducting protrusion 21 in Embodiment 1 is obtained by integrally stamping the plates. Therefore, in this embodiment, the entire small heat exchange channel is formed between the two outer heat exchange surfaces, and the heat conduction protrusion 21 can be connected to the plate by a fixed method such as welding.
