Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, specifically a rapid assembly modular liquid cooling plate. Background Technology

[0002] With the development of the new energy industry, there are more and more new energy vehicles on the market. New energy vehicles use battery packs to provide power. When the battery packs are in use, they will generate high temperatures and need to be cooled and dissipated with the help of liquid cooling plates. Liquid cooling plates have excellent heat dissipation performance. For medium and high power density equipment, liquid cooling plates can effectively remove the heat dissipation in power devices, printed circuit board assemblies or sub-equipment equipment.

[0003] An existing liquid cooling plate, such as the one described in Chinese patent application number CN201710050871.8, includes a liquid cooling plate base, a cooling liquid channel on one side of the liquid cooling plate base, a cooling liquid channel cover on the side where the cooling liquid channel is located, and at least one heat spreader for mounting corresponding heating elements on the other side of the liquid cooling plate base. The heat spreader has a heat spreader cavity inside, and the liquid cooling plate base and the heat spreader are thermally connected. The cooling liquid channel includes a heat spreader cooling liquid channel portion facing the heat spreader and a peripheral cooling liquid channel portion located on the heat spreader cooling liquid channel portion. However, the existing liquid cooling plate can only be used individually, its size cannot be changed, its application range is small, and it cannot be spliced ​​and assembled between multiple sets of liquid cooling plates according to requirements.

[0004] Therefore, we propose a rapid assembly modular liquid cooling plate to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid assembly modular liquid cooling plate, comprising a temperature-conducting plate:

[0007] The temperature-conducting plate is internally fitted with a liquid cooling pipe, and a first connecting pipe is embedded in the left side of the liquid cooling pipe. The liquid cooling pipe is fixedly connected to the first connecting pipe. A splicing plate is fixed in the middle of the temperature-conducting plate, and a splicing groove is opened in the middle of the right side of the temperature-conducting plate.

[0008] The right end of the liquid cooling pipe is connected to a second connecting pipe, and a sealing plate is provided inside the second connecting pipe. A limit rod is connected to the middle of the sealing plate, and a reset spring is sleeved on the left side of the limit rod. A positioning plate passes through the left side of the limit rod.

[0009] The lower end of the heat-conducting plate is fitted with a heat dissipation fin, and a fixing bolt passes through the lower end of the heat dissipation fin, with the upper end of the fixing bolt threadedly connected to the heat-conducting plate.

The connecting seat is engaged with the first connecting pipe, and the connecting conduit passes through the connecting seat and communicates with the first connecting pipe.

[0011] By adopting the above technical solution, the connection between the connecting conduit and the liquid cooling pipe is facilitated through the cooperation of the first connecting pipe and the connecting seat, thereby controlling the flow of coolant from inside the liquid cooling pipe.

[0012] Preferably, there are two sets of splicing plates and splicing grooves, and the splicing plates and splicing grooves are symmetrically distributed on both sides of the left and right central axes of the temperature guide plate. The splicing plates and splicing grooves are engaged and connected. A positioning bolt passes through the upper end of the splicing groove, and the bottom end of the positioning bolt is threaded to the temperature guide plate. The middle part of the positioning bolt passes through the splicing plate.

[0013] By adopting the above technical solution, multiple sets of temperature-conducting plates can be connected through the cooperation between splicing plates, splicing grooves and positioning bolts, and modular disassembly and assembly can be performed to improve the convenience of operation.

[0014] Preferably, the left end of the temperature-conducting plate is connected to the front and rear sides of the plate, and the right end of the temperature-conducting plate is provided with positioning grooves on the front and rear sides, and the positioning grooves are engaged with the positioning blocks.

[0015] By adopting the above technical solution, the stability of the temperature-conducting plates during splicing can be improved through the cooperation of the positioning groove and the positioning block.

[0016] Preferably, the first connecting pipe and the second connecting pipe are engaged and connected, the right end of the sealing plate is designed as a four-sided pyramid, and the sealing plate is engaged and connected to the inner wall of the second connecting pipe.

[0017] By adopting the above technical solution, the interlocking and conductive connection between the first connecting pipe and the second connecting pipe facilitates the interconnection of internal liquid cooling pipes when multiple sets of temperature-conducting plates are spliced ​​together.

[0018] Preferably, a push plate is fixed in the middle of the first connecting tube, and the push plate is in contact with the right end of the limiting rod. The positioning plate is fixed to the inner wall of the second connecting tube, and the positioning plate is slidably connected to the limiting rod. The left and right ends of the reset spring are in contact with the positioning plate and the sealing plate, respectively.

[0019] By adopting the above technical solution, through the design of the push plate, when the first connecting pipe and the second connecting pipe are connected, the push plate moves into the second connecting pipe and pushes the limiting rod to move into it. The limiting rod drives the sealing plate to move and release the seal on the second connecting pipe, maintaining the flow conduction between multiple sets of liquid cooling pipes.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the rapid assembly modular liquid cooling plate;

[0021] 1. The modular design allows for the quick assembly of multiple sets of heat-conducting plates. The overall area of ​​the liquid cooling plate can be adjusted according to requirements or actual use. The operation is simple and convenient, and the application range is wide. During assembly, the liquid cooling pipes inside the heat-conducting plates can be mutually guided, ensuring that the coolant can flow inside multiple sets of heat-conducting plates.

[0022] 2. By setting a spring compression sealing structure, the right end of the liquid cooling pipe can be sealed when the temperature guide plate is used alone or when no other temperature guide plate is connected on the right side. When multiple temperature guide plates are connected, the seal is released by compression, so that the internal cooling pipes of multiple temperature guide plates can be connected. The operation is simple and the assembly is convenient. Attached Figure Description
