Abstract
Description
Technical Field
[0001] This application relates to the field of cooling water plate technology, and in particular to a harmonica tube type water plate. Background Technology
[0002] Currently, the overall replacement cycle of new energy vehicles is extremely fast, resulting in a short production cycle for parts. Therefore, reducing the production cycle of parts is of great significance to the rapid development of new energy vehicles.
[0003] As a crucial component of the battery pack's internal thermal management system, the water-cooling system is complex and requires high precision in its manufacturing process. The commonly used water-cooling plate in this system is the harmonica tube water-cooling plate, which mainly consists of connecting pipes, manifolds, harmonica tubes, plugs, and water-insulating plates. Currently, harmonica water-cooling plates primarily use high-frequency welding to assemble the various components; however, this method increases the production cycle of the harmonica water-cooling plate, often failing to meet customer production delivery requirements.
[0004] In addition, the water collection tank of the relevant technology needs to be covered with a layer of flux after extrusion molding, which increases the production cycle of the water collection tank. The harmonica board is brazed to the water collection tank through the flux on the surface of the water collection tank. However, after brazing, the surface of the water collection tank is not clean due to the flow of flux. Summary of the Invention
[0005] In order to shorten the production cycle of water-cooled plates and improve the cleanliness of the water collection tank surface, this application provides a harmonica-style water-cooled plate.
[0006] The harmonica tube-type water-cooled plate provided in this application adopts the following technical solution:
[0007] A harmonica tube type water-cooled plate includes a water collection tank and a harmonica tube. A bracket is provided on the water collection tank. An flux layer is provided on the surface of the bracket near the water collection tank and on the surface away from the water collection tank. The end of the harmonica tube passes through the bracket and is inserted into the water collection tank.
[0008] By adopting the above technical solution, the water collection tank and harmonica tube are fixed by brazing with a bracket, which reduces the problem of needing to add an extra flux layer during the production of the water collection tank in related technologies, and shortens the production cycle of the water collection tank.
[0009] Meanwhile, the flux layer is placed on the support, which can effectively ensure the cleanliness of the water tank surface and further improve the production quality of the harmonica tube type water-cooled plate.
[0010] In addition, the water collection tank and harmonica tube are fixed by brazing with a bracket, which can effectively improve the overall brazing strength and increase the service life of the water cooling plate.
[0011] Optionally, the bracket is provided with an annular protrusion that is inserted into the water collection tank, and the annular protrusion has a through hole for inserting a harmonica tube.
[0012] By adopting the above technical solution, the outer wall of the annular protrusion fits into the water collection tank, improving the structural strength after the support is connected to the water collection tank. The harmonica tube is inserted into the annular protrusion through the through hole and connected to the support.
[0013] Optionally, the length of the bracket is less than the length of the water collection tank, and the width of the bracket is less than the width of the water collection tank.
[0014] By adopting the above technical solution, when the flux layer on the support melts, the length and width of the support can be limited to prevent the flux layer from flowing onto the surface of the water collection tank, thus ensuring the cleanliness of the water collection tank surface.
[0015] Optionally, multiple water collection tanks are provided, one of which has a water-blocking groove, and a water-blocking plate is provided inside the water-blocking groove to separate the inner cavity of the water collection tank. The water-blocking plate is provided with a flux layer.
[0016] By adopting the above technical solution, compared to directly molding two non-interconnected inner cavities into the water collection tank, the water-blocking plate and the water collection tank are molded separately and then assembled. The water-blocking plate separates the two cavities inside the water collection tank, which can further improve the production speed of the water collection tank and shorten the production cycle of the water-cooled plate.
[0017] Optionally, the water-proof plate is provided with an installation block, and the bracket is provided with a fixing groove, into which the installation block is inserted.
[0018] By adopting the above technical solution, the water-proof sheet is connected to the bracket through the mounting block, which can minimize the movement of the water-proof sheet due to fluid impact.
[0019] Optionally, a connecting pipe is provided on the water collection tank with a water-tight groove, and one end of the connecting pipe extends into the water collection tank.
[0020] By adopting the above technical solution, the user can easily put a welding ring on the part of the connecting pipe that extends into the water collection tank, which facilitates the brazing and fixing of the connecting pipe to the water collection tank.
[0021] Optionally, a water passage groove is provided on the water collection tank, one end of the connecting pipe extends into the water passage groove, and a limiting ring is fitted on the connecting pipe, the diameter of the limiting ring being larger than the diameter of the water passage groove.
[0022] By adopting the above technical solution, during brazing, the connecting pipe extends into the water collection tank through the water passage groove. Since the diameter of the limiting ring is larger than the diameter of the water passage groove, the length of the connecting pipe inserted into the water collection tank can be limited.
[0023] Optionally, both ends of the water collection tank are equipped with plugs, and the plugs are provided with a layer of flux.
[0024] By adopting the above technical solution, the flux layer on the plug can effectively shorten the time for welding the plug onto the water collection tank, further increasing the production efficiency of the harmonica-type water-cooled plate and shortening the production cycle.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. The water collection tank and harmonica tube are fixed by brazing through the flux layer on the bracket, which can effectively shorten the production cycle of the harmonica-type water-cooled plate, increase production efficiency, and at the same time effectively ensure the cleanliness of the surface of the water collection tank, further improving the production quality of the harmonica tube-type water-cooled plate.
[0027] 2. Effectively improves the connection strength between the water collection tank and the harmonica tube, further extending the service life of the harmonica-style water-cooled plate. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0035] A harmonica tube type water-cooled plate, reference Figure 1 It includes two water collection tanks 1 and two harmonica tubes 2. A bracket 4 is provided on the side wall surface of the two water collection tanks 1 that are relatively close to each other. The two harmonica tubes 2 are arranged in parallel along their own width direction. The two ends of the two harmonica tubes 2 in the same length direction are connected to the adjacent water collection tanks 1 through a bracket 4.
[0036] refer to Figure 1 , Figure 2 A plug 6 is provided at both ends of the water collection tank 1 along its length. A sealing layer 601 is fixedly connected to the side of the plug 6 closest to the water collection tank 1. The sealing layer 601 extends into the water collection tank 1 and fits against the inner wall of the water collection tank 1. A flux layer is provided at the connection between the plug 6 and the side wall of the water collection tank 1. The plug 6 and the water collection tank 1 are fixed by welding through the flux layer.
[0037] refer to Figure 2 , Figure 3 One of the water collection tanks 1 has a water-blocking groove 8, and a water-blocking plate 5 is provided in the water-blocking groove 8. A flux layer is provided on the contact surface between the water-blocking plate 5 and the water-blocking groove 8.
[0038] Two water passage grooves 7 are provided on the surface of the water collection tank 1 away from the support 4, which is equipped with a water-blocking groove 8. The two water passage grooves 7 are arranged along the length of the water collection tank 1 and are respectively located on both sides of the water-blocking groove 8. Both water passage grooves 7 are connected to the inner cavity of the water collection tank 1.
[0039] Two connecting pipes 3 are provided on the side of the water collection tank 1 away from the support 4, with the ends of the two connecting pipes 3 respectively inserted into the inner cavity of the water collection tank 1 through different water passages 7, and the sidewalls of the connecting pipes 3 are in contact with the water passages 7. The ends of the connecting pipes 3 in the inner cavity of the water collection tank 1 are used for welding rings to be fitted, and the welding rings are melted by brazing, thereby fixing the connecting pipes 3 to the water collection tank 1.
[0040] Reference Figure 3 , Figure 4 A limiting ring 301 is fitted on the connecting pipe 3. The connecting pipe 3 and the limiting ring 301 are integrally formed. The diameter of the limiting ring 301 is larger than the diameter of the water channel 7, which can be used to limit the length of the connecting pipe 3 extending into the water collection tank 1.
[0041] refer to Figure 3 , Figure 4 Two water guide grooves 9 are provided on the opposing surfaces of the two water collection tanks 1. The two water guide grooves 9 are arranged along the length of the water collection tank 1, and the two water guide grooves 9 are respectively located on both sides of the water isolation groove 8.
[0042] refer to Figure 2 , Figure 5 The bracket 4 has flux layers on both the side closest to the water collection tank 1 and the side furthest from the water collection tank 1. The length extension direction of the bracket 4 is consistent with the length extension direction of the water collection tank 1. The bracket 4 has two annular protrusions 401 integrally formed towards the adjacent water collection tank 1 by stamping. Both the inner and outer walls of the annular protrusions 401 are provided with flux layers. The two annular protrusions 401 are arranged on the bracket 4 along its own length extension direction. A fixing groove 402 penetrating the bracket 4 is provided on the bracket 4, located between the two annular protrusions 401.
[0043] The annular protrusion 401 is correspondingly arranged with the water guide groove 9 on the adjacent water collection tank 1. The annular protrusion 401 is inserted into the water guide groove 9 and the end of the annular protrusion 401 extends into the water collection tank 1. The outer wall of the annular protrusion 401 is in contact with the water guide groove 9. The connection between the support 4 and the water collection tank 1 is enhanced by the two annular protrusions 401 and the two water guide grooves 9.
[0044] Reference Figure 1 , Figure 5 A mounting block 501 is fixedly connected to the side of the water-proof plate 5 near the bracket 4. The mounting block 501 extends to the side near the bracket 4. The mounting block 501 corresponds to the position of the fixing groove 402. The mounting frame 501 extends into the fixing groove 402.
[0045] refer to Figure 4 The two ends of the harmonica tube 2 are respectively inserted into one of the annular protrusions 401 of different brackets, and are inserted into the collector 1 through the inner hole of the annular protrusion 401.
[0046] The specific implementation principle of this application is as follows: During production, the connecting pipe 3 and the water-blocking plate 5 are initially fixed to the water collection tank 1 with the water-blocking groove 8 by spot welding. A welding ring is fitted on the part of the connecting pipe 3 that extends into the water collection tank. The sealing layer 601 on the plug 6 extends into and is installed on both ends of the two water collection tanks 1. Then, the bracket 4 is installed on the corresponding water collection tank 1 and pre-fixed by spot welding. Next, the two ends of the harmonica tube 2 are inserted into the water collection tank 1 through the annular protrusions 401 on different brackets 4, and the harmonica tube 2 is also spot welded to the bracket 1.
[0047] The assembled water-cooled plate is conveyed to the brazing furnace. The high temperature in the brazing furnace melts the flux layer and brazes the harmonica tube 2 connected to the bracket 2 to the water collection tank 1. The molten flux further fills the capillaries, improving the sealing of the connection between the harmonica tube 2 and the water collection tank 1, and at the same time improving the brazing strength between the harmonica tube 2 and the water collection tank 1.
[0048] Since the length of the bracket is less than the length of the water collection tank 1 and the width of the bracket is less than the width of the water collection tank 1, it can effectively prevent the flux on the bracket 4 from flowing onto the water collection tank 1 when it melts, thus effectively ensuring the surface cleanliness of the water collection tank 1.
[0049] In addition, the weld ring on the connecting pipe 3 melts and flows into the inside of the limiting ring 301, further capillary filling the connection between the connecting pipe 3 and the water collection tank 1, thus improving the sealing performance.
[0050] After the flux layer on the water-isolating plate 5 melts, the flux flows into the interior of the water collection tank 1, capillarily filling the space between the water-isolating plate 5 and the water-isolating groove 8. At the same time, it can further fix the water-isolating plate 5 to the water collection tank 1, preventing the water-isolating plate 5 from shifting after it is put into use.
[0051] In addition, it should be noted that after the flux layer on the bracket 4 melts, the flux flows and brazes the bracket 4 to the water-proof plate 5, further improving the stability of the water-proof plate 5 in use.
[0052] Meanwhile, after the flux layer on the plug 6 melts, the flux flows into the interior of the water collection tank 1 and fills the tank, effectively improving the sealing performance of the plug 6.
[0053] By sending the assembled water-cooled plate into a brazing furnace and melting the flux layer on the assembled water-cooled plate through high temperature, the parts on the water-cooled plate are quickly brazed, which effectively speeds up the production efficiency of the harmonica-type water-cooled plate and shortens the production cycle of the harmonica-type water-cooled plate.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
