请参考图1至图12，换热器100通常应用于空调***200中，换热器100是气体与液体热交换器中使用最为广泛的一种换热设备，它通过在普通的换热管上加装翅片来达到强化传热的目的。Please refer to Figures 1 to 12. The heat exchanger 100 is usually used in the air conditioning system 200. The heat exchanger 100 is the most widely used heat exchange equipment among gas and liquid heat exchangers. It passes through ordinary heat exchange tubes. Fins are added to enhance heat transfer.
相关技术中的换热器中，由于扁管的预留管段发生了折弯扭转，在预留管段处没有设置翅片，折弯后相邻两根预留管段之间具有较大的缝隙，这会产生漏风，影响换热性能。而且没有翅片的保护，扁管的预留管段直接裸露在外，容易受到腐蚀和外力损伤。In the heat exchanger in the related art, because the reserved pipe section of the flat tube is bent and twisted, there are no fins at the reserved pipe section, and there is a large gap between two adjacent reserved pipe sections after bending. This will cause air leakage and affect heat exchange performance. Moreover, without the protection of fins, the reserved pipe section of the flat tube is directly exposed and is susceptible to corrosion and external force damage.
为解决相关技术中的换热器中所存在的问题，本申请提供了一种换热器100，包括第一翅片10和多根并列且间隔设置的扁管20，扁管20包括预留管段21，扁管20在预留管段21处折弯，第一翅片10连接于预留管段21，且 第一翅片10能够遮住多根预留管段21之间的缝隙；沿预留管段21延伸方向，第一翅片10的宽度为W1，第一翅片10设置有n根，预留管段21的长度为L，W1、n、L满足以下关系式：W1≤L/n。In order to solve the problems existing in heat exchangers in related technologies, the present application provides a heat exchanger 100, which includes a first fin 10 and a plurality of parallel and spaced apart flat tubes 20. The flat tubes 20 include reserved Pipe section 21, the flat tube 20 is bent at the reserved pipe section 21, the first fin 10 is connected to the reserved pipe section 21, and The first fin 10 can cover the gaps between the plurality of reserved pipe sections 21; along the extending direction of the reserved pipe section 21, the width of the first fin 10 is W 1 , and n number of first fins 10 are provided. The length of the pipe section 21 is L, and W 1 , n, and L satisfy the following relationship: W 1 ≤ L/n.
需要说明的是，本申请通过使得W1、n、L满足关系式W1≤L/n，从而避免第一翅片10互相交叠，进而影响换热器100的折弯，以至于换热器100折弯时第一翅片10与预留管段21之间无法焊接。其中，此处指的预留管段21的长度L为换热器100折弯前预留管段21的总长度。It should be noted that this application makes W 1 , n, and L satisfy the relational expression W 1 ≤ L/n, thereby avoiding the first fins 10 from overlapping each other, which in turn affects the bending of the heat exchanger 100 and reduces the heat exchange. When the tool 100 is bent, the first fin 10 and the reserved pipe section 21 cannot be welded. The length L of the reserved pipe section 21 referred to here is the total length of the reserved pipe section 21 before the heat exchanger 100 is bent.
换热器100在预留管段21处折弯呈V型、直线型、L型等，直线型为图3中预留管段21扭转180°形成多排的形状。预留管段21处折弯呈直线型时，预留管段21多次折弯并呈多排设置。The heat exchanger 100 is bent at the reserved pipe section 21 to form a V-shape, a linear shape, an L-shape, etc. The linear shape is a shape in which the reserved pipe section 21 is twisted 180° to form multiple rows in Figure 3 . When the reserved pipe section 21 is bent in a straight line, the reserved pipe section 21 is bent multiple times and arranged in multiple rows.
如图1所示，换热器100还包括第二翅片30，扁管20还包括第一管段22和第二管段23，预留管段21的两端分别连接第一管段22和第二管段23，多根第一管段22并列且间隔设置，第二翅片30布设于多根并列且间隔设置的第一管段22之间；多根第二管段23并列且间隔设置，第二翅片30布设于多根并列且间隔设置的第二管段23之间。As shown in Figure 1, the heat exchanger 100 also includes a second fin 30, the flat tube 20 also includes a first tube section 22 and a second tube section 23, and the two ends of the reserved tube section 21 are connected to the first tube section 22 and the second tube section respectively. 23. A plurality of first pipe sections 22 are arranged in parallel and at intervals, and the second fins 30 are arranged between a plurality of first pipe sections 22 which are arranged in parallel and at intervals; a plurality of second pipe sections 23 are arranged in parallel and at intervals, and the second fins 30 It is arranged between a plurality of parallel and spaced apart second pipe sections 23 .
预留管段21位于第一管段22和第二管段23之间，相关技术的换热器中，预留管段处由于通常用于换热器折弯，因此在预留管段处不设置有第二翅片30，没有第二翅片30的保护，预留管段直接裸露在外，容易受到腐蚀和外力损伤。但是如果在预留管段处设置第二翅片30，虽保护了预留管段不受损伤，但是在预留管段折弯的过程中第二翅片30容易发生撕裂，因此在解决保护预留管段不受损伤的基础上还得保证在预留管段折弯的过程中第二翅片30不会发生撕裂。基于此，本申请在预留管段21处设置了一种特殊的翅片即第一翅片10。 The reserved pipe section 21 is located between the first pipe section 22 and the second pipe section 23. In the heat exchanger of the related art, the reserved pipe section is usually used for bending of the heat exchanger, so there is no second pipe section provided at the reserved pipe section. The fin 30 is not protected by the second fin 30, and the reserved pipe section is directly exposed, which is easily susceptible to corrosion and external force damage. However, if the second fin 30 is provided at the reserved pipe section, although the reserved pipe section is protected from damage, the second fin 30 is prone to tearing during the bending process of the reserved pipe section. Therefore, it is difficult to solve the problem of protecting the reserved pipe section. On the basis that the pipe section is not damaged, it is also necessary to ensure that the second fin 30 will not be torn during the bending process of the reserved pipe section. Based on this, this application provides a special fin, namely the first fin 10, at the reserved pipe section 21.
如图2及图3所示，预留管段21包括互相连接的直管段211和弯管段212。直管段211的一端连接第一管段22及/或第二管段23，弯管段212的两端分别连接直管段211。As shown in FIGS. 2 and 3 , the reserved pipe section 21 includes a straight pipe section 211 and a curved pipe section 212 that are connected to each other. One end of the straight pipe section 211 is connected to the first pipe section 22 and/or the second pipe section 23 , and both ends of the bent pipe section 212 are connected to the straight pipe section 211 respectively.
值得注意的是，预留管段21折弯后，至少要设置有一部分直管段211，不能全部设置为弯管段212，如若全部为弯管段212则会大大降低换热器100折弯后预留管段21处的强度，为了增强预留管段21折弯后的强度，需保证折弯后的预留管段21设置有直管段211。It is worth noting that after the reserved pipe sections 21 are bent, at least a part of the straight pipe sections 211 must be provided, and all of them cannot be set as curved pipe sections 212. If all of the reserved pipe sections 212 are curved pipe sections 212, the pre-bent heat exchanger 100 will be greatly reduced. In order to enhance the strength of the reserved pipe section 21 after bending, it is necessary to ensure that the bent reserved pipe section 21 is provided with a straight pipe section 211 .
进一步地，第一翅片10连接于直管段211部分的宽度大于等于第一翅片10连接于弯管段212部分的宽度。Furthermore, the width of the part of the first fin 10 connected to the straight pipe section 211 is greater than or equal to the width of the part of the first fin 10 connected to the bent pipe section 212 .
需要说明的是，第一翅片10需要尽可能多的连接于直管段211部分而非弯管段212部分，因为弯管段212部分承受的扭矩较大，连接于弯管段212部分的第一翅片10折弯过程中存在的撕裂风险较大，而且弯管段212部分的结构强度低于直管段211部分的结构强度，因此需要使得第一翅片10尽可能多的连接于直管段211部分而非弯管段212部分，从而使得第一翅片10的扭曲度较小，不容易被撕裂。It should be noted that the first fin 10 needs to be connected to the straight pipe section 211 as much as possible instead of the curved pipe section 212 because the curved pipe section 212 bears a larger torque, and the first fin 10 connected to the curved pipe section 212 is There is a greater risk of tearing during the bending process of the first fin 10, and the structural strength of the bent pipe section 212 is lower than that of the straight pipe section 211. Therefore, it is necessary to connect the first fin 10 to as many straight pipes as possible. The pipe section 211 part is not the bent pipe section 212 part, so that the first fin 10 has a smaller twist and is not easily torn.
进一步地，预留管段21的宽度为W2，W2和W1满足关系式W1≤W2。也就是说，第一翅片10的宽度W1需要尽可能的小，本申请将第一翅片10的宽度W1限定为小于等于预留管段21的宽度W2，只有当第一翅片10的宽度W1尽可能的小的时候，才能够更好的保证第一翅片10更多的连接于直管段211部分，从而使得换热器100折弯时第一翅片10不容易被撕裂。Furthermore, the width of the reserved pipe section 21 is W 2 , and W 2 and W 1 satisfy the relationship W 1 ≤ W 2 . That is to say, the width W 1 of the first fin 10 needs to be as small as possible. This application limits the width W 1 of the first fin 10 to be less than or equal to the width W 2 of the reserved pipe section 21 . Only when the first fin When the width W 1 of 10 is as small as possible, it can better ensure that the first fin 10 is more connected to the straight pipe section 211 , so that the first fin 10 is not easily damaged when the heat exchanger 100 is bent. tear.
具体地，预留管段21的宽度W2和预留管段21的长度L满足关系式L≥2W2。Specifically, the width W 2 of the reserved pipe section 21 and the length L of the reserved pipe section 21 satisfy the relational expression L≥2W 2 .
需要说明的是，预留管段21的长度L需要足够的长，本申请将预留管段 21的长度L限定为大于等于两倍的预留管段21的宽度W2，只有当预留管段21的长度L足够长的时候，才能够保证预留管段21至少设置有直管段211，从而增强预留管段21的结构强度。可以理解的是，通过使得W2和L满足关系式L≥2W2，从而使得所述换热器100折弯时所述第一翅片10不容易被撕裂。It should be noted that the length L of the reserved pipe section 21 needs to be long enough. In this application, the reserved pipe section 21 will be The length L of 21 is limited to be greater than or equal to twice the width W 2 of the reserved pipe section 21. Only when the length L of the reserved pipe section 21 is long enough can it be ensured that the reserved pipe section 21 is provided with at least a straight pipe section 211, thereby enhancing The structural strength of the pipe section 21 is reserved. It can be understood that by making W 2 and L satisfy the relationship L≥2W 2 , the first fin 10 is not easily torn when the heat exchanger 100 is bent.
如图4至图11所示，第一翅片10具有多个卡槽11，多卡槽11沿第一翅片10的长度方向间隔设置，每根预留管段21的至少一部分结构位于其中一个卡槽11内。如此使得第一翅片10与多根预留管段21连接强度更高，并且第一翅片10在随预留管段21折弯的过程中，易发生变形，变形后也能够对多根预留管段21之间的缝隙进行良好的遮挡。As shown in Figures 4 to 11, the first fin 10 has a plurality of slots 11. The plurality of slots 11 are spaced apart along the length direction of the first fin 10, and at least a part of the structure of each reserved pipe section 21 is located in one of them. inside the card slot 11. In this way, the connection strength between the first fin 10 and the plurality of reserved pipe sections 21 is higher, and the first fin 10 is easily deformed during the bending process with the reserved pipe sections 21, and can also be used to connect multiple reserved pipe sections 21 after deformation. The gaps between the pipe sections 21 are well shielded.
其中，卡槽11的数量可以设置为与预留管段21的数量相等，多根预留管段21与多个卡槽11一一对应设置，如图4、图7、图8、图9、图10和图11中的实施例所示。Among them, the number of card slots 11 can be set to be equal to the number of reserved pipe sections 21, and multiple reserved pipe sections 21 are arranged in one-to-one correspondence with multiple card slots 11, as shown in Figures 4, 7, 8, 9, and 10 and 11.
或者，卡槽11的数量可以设置为大于预留管段21的数量；在相邻两个预留管段21之间，具有至少一个未与预留管段21配合的卡槽11。这样第一翅片10在随预留管段21折弯的过程中更易发生变形，从而堵住预留管段21之间的缝隙，加强防漏风作用，如图6和图7中所示。Alternatively, the number of clamping slots 11 can be set to be greater than the number of reserved pipe sections 21; between two adjacent reserved pipe sections 21, there is at least one clamping slot 11 that does not cooperate with the reserved pipe sections 21. In this way, the first fin 10 is more likely to deform during the bending process with the reserved pipe sections 21, thereby blocking the gaps between the reserved pipe sections 21 and enhancing the air leakage prevention effect, as shown in Figures 6 and 7.
在上述实施例中，第一翅片10包括多个顺次连接的翅片段12，每个翅片段12位于相邻两根预留管段21之间，翅片段12的横截面可以设置为弧型(图10中的实施例)、直线型(图4中的实施例、图7中实施例和图8中的实施例)、斜线型(图9中的实施例)、V型(图11中的实施例)或波浪型(图5中的实施例和图6中的实施例)。In the above embodiment, the first fin 10 includes a plurality of fin segments 12 connected in sequence. Each fin segment 12 is located between two adjacent reserved pipe segments 21 . The cross-section of the fin segments 12 can be configured to be arc-shaped. (the embodiment in Figure 10), linear type (the embodiment in Figure 4, the embodiment in Figure 7 and the embodiment in Figure 8), diagonal type (the embodiment in Figure 9), V-shaped (Figure 11 The embodiment in Figure 5) or the wave type (the embodiment in Figure 5 and the embodiment in Figure 6).
如图9所示，在一些实施例中，第一翅片10将多个预留管段21中的多 个缝隙均进行了遮挡，并且第一翅片10在随预留管段21折弯后，也不会与预留管段21脱离，连接效果好。As shown in Figure 9, in some embodiments, the first fin 10 separates multiple reserved pipe sections 21. Each gap is blocked, and the first fin 10 will not be separated from the reserved pipe section 21 after being bent along with the reserved pipe section 21, and the connection effect is good.
如图8所示，在一些实施例中，第一翅片10分布于每根预留管段21的两侧。当然，在其他实施例中，第一翅片10既可以分布于每根预留管段21的其中一侧，也可以每根预留管段21的两侧均分布有第一翅片10，在此不作限定。As shown in FIG. 8 , in some embodiments, the first fins 10 are distributed on both sides of each reserved pipe section 21 . Of course, in other embodiments, the first fins 10 can be distributed on one side of each reserved pipe section 21 , or the first fins 10 can be distributed on both sides of each reserved pipe section 21 . Here, Not limited.
如图6所示，在一些实施例中，扁管20的宽度为W3，沿着扁管20的宽度方向，翅片段12的高度h＞W3/2。也就是说，翅片段12与扁管20之间的接触深度大于扁管20宽度的一半，提升翅片段12与扁管20之间的接触面积也能够进一步增强第一翅片10与扁管20之间的连接强度，同时，增加第一翅片10的换热面积；当然，在其他实施例中，翅片段12与扁管20之间的接触深度也可以小于等于扁管20宽度的一半，在此不作限定。As shown in FIG. 6 , in some embodiments, the width of the flat tube 20 is W 3 , and along the width direction of the flat tube 20 , the height h of the fin segment 12 is > W 3 /2. That is to say, the contact depth between the fin segment 12 and the flat tube 20 is greater than half the width of the flat tube 20 , and increasing the contact area between the fin segment 12 and the flat tube 20 can also further enhance the contact between the first fin 10 and the flat tube 20 The connection strength between them also increases the heat exchange area of the first fin 10; of course, in other embodiments, the contact depth between the fin segments 12 and the flat tube 20 can also be less than or equal to half the width of the flat tube 20, No limitation is made here.
值得注意的是，上述各实施例可以互相组合形成新的实施例，且翅片段12横截面的形状也不局限于上述形状，还可以为其他形状，第一翅片10和预留管段21之间的连接方式也不局限于上述方式，还可以为其他方式，在此均不作限定。It is worth noting that the above-mentioned embodiments can be combined with each other to form new embodiments, and the shape of the cross-section of the fin segment 12 is not limited to the above-mentioned shape, and can also be other shapes, such as the first fin 10 and the reserved pipe segment 21 The connection method is not limited to the above method, and can also be other methods, which are not limited here.
在上述实施例中，第一翅片10由复合铝箔制成。由于复合铝箔材料导热性好，易变形，在预留管段21折弯的过程中，易于随预留管段21发生变形，保持对缝隙的遮挡，提高换热和防护效果。In the above embodiment, the first fin 10 is made of composite aluminum foil. Since the composite aluminum foil material has good thermal conductivity and is easy to deform, during the bending process of the reserved pipe section 21, it is easy to deform along with the reserved pipe section 21, keeping the gap blocked and improving the heat exchange and protection effect.
可选地，第一翅片10与预留管段21焊接，这样连接强度高。复合铝箔可由两层或多层复合而成，其中，一层熔点高，另一层熔点低，或表层熔点低，中间层熔点高。在焊接时，将复合铝箔中熔点低的一层与预留管段21配合。 Optionally, the first fin 10 is welded to the reserved pipe section 21, so that the connection strength is high. Composite aluminum foil can be composed of two or more layers. One layer has a high melting point and the other layer has a low melting point, or the surface layer has a low melting point and the middle layer has a high melting point. During welding, the layer with a lower melting point in the composite aluminum foil is matched with the reserved pipe section 21.
在上述实施例中，第一翅片10的电位低于预留管段21的电位。这样在使用换热器100的过程中，如果发生腐蚀，会先腐蚀电位较低的第一翅片10，然后才腐蚀预留管段21，从而通过第一翅片10对预留管段21进行防护，提高换热器100的耐用性。In the above embodiment, the potential of the first fin 10 is lower than the potential of the reserved pipe section 21 . In this way, during the use of the heat exchanger 100, if corrosion occurs, the first fin 10 with a lower potential will be corroded first, and then the reserved pipe section 21 will be corroded, so that the reserved pipe section 21 is protected by the first fin 10 , improve the durability of the heat exchanger 100.
本申请提供的换热器100，通过使得W1、n、L满足关系式W1≤L/n，从而避免所述第一翅片10互相交叠，进而影响所述换热器100的折弯，以至于所述换热器100折弯时所述第一翅片10与所述预留管段21之间无法焊接。The heat exchanger 100 provided in this application makes W 1 , n, and L satisfy the relationship W 1 ≤ L/n, thereby preventing the first fins 10 from overlapping each other, thereby affecting the folding of the heat exchanger 100 . Bending, so that the first fin 10 and the reserved pipe section 21 cannot be welded when the heat exchanger 100 is bent.
