Description

Technical Field

[0001] This utility model relates to a locally adjustable enhanced heat dissipation liquid cooling plate, which belongs to the field of heat dissipation technology for new energy batteries. Background Technology

[0002] Currently, liquid cooling plates are installed at the bottom of the battery box of new energy batteries to enhance the heat dissipation of the battery module. However, most existing liquid cooling plate manufacturing solutions are customized production solutions. Depending on the performance parameters, size, and distribution of the battery cell module, different flow channel schemes need to be designed and different molds need to be made, which increases the manufacturing cost. Moreover, the flow channel structure often suffers from poor layout and aesthetics in order to meet the temperature uniformity performance of the battery cell. Therefore, the existing solutions have disadvantages such as high design cost, long development cycle, and unattractive appearance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a locally adjustable enhanced heat dissipation liquid cooling plate that effectively improves heat dissipation, has low manufacturing cost, and can be adapted to different heat dissipation schemes.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A locally adjustable enhanced heat dissipation liquid cooling plate includes a liquid cooling plate body and turbulence fins for achieving local turbulence. The liquid cooling plate body includes a flat plate and a flow channel plate. The flow channel plate is a stamped integral structure with multiple flow channel grooves on the plate body. The flat plate and the flow channel plate are fixed together by brazing. A flow channel cavity for coolant flow is formed between the flat plate and the flow channel grooves. An inlet and an outlet communicating with the flow channel cavity are respectively provided on both sides of the flat plate. The turbulence fins are installed in the flow channel cavity and realize local turbulence of the coolant in the flow channel cavity.

[0006] Preferably, the turbulence fins are corrugated thin plate structures.

[0007] Preferably, the wave-shaped turbulence fins are composed of multiple unconnected and laterally placed S-shaped aluminum sheets.

[0008] Preferably, the turbulence fins are fixed in the flow channel cavity by limiting device or spot welding.

[0009] Preferably, the thickness of the turbulence fins is set to 0.1-0.2 mm.

[0010] Preferably, the spacing between the plurality of turbulence fins is set between 5-10 mm.

[0011] Compared with the prior art, the advantages of this utility model are: the locally adjustable enhanced heat dissipation liquid cooling plate can adopt a standardized and statistical appearance design, thus making the design more aesthetically pleasing and easier for customers to accept; moreover, when there are different heat dissipation schemes, it is only necessary to add or reduce the corrugated fins locally to form turbulence, thereby enhancing or reducing heat dissipation to achieve uniform temperature, without the need for additional heat dissipation scheme design, reducing design and mold opening costs, reducing design time, improving design efficiency, and shortening the design and development cycle. The product structure can be adjusted in real time according to the sample testing structure (the flow channel plate structure does not need to be adjusted, only the number and position of the fins need to be changed), without the need for additional design and new sample mold, greatly shortening the development cycle. Therefore, while achieving effective heat dissipation, it saves costs to a large extent, thus having high practicality. Attached Figure Description

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figure 1 , Figure 2The illustrated type of locally adjustable enhanced heat dissipation liquid cooling plate includes a liquid cooling plate body and turbulence fins 1 for achieving localized turbulence. The liquid cooling plate body includes a flat plate 2 and a flow channel plate 3. The flow channel plate 3 is a stamped integral structure with multiple flow channel grooves 4 on its body. The flat plate 2 and the flow channel plate 3 are connected and fixed by brazing, forming a flow channel cavity for coolant flow between the flat plate 2 and the flow channel grooves 4. An inlet 5 and an outlet 6 communicating with the flow channel cavity are respectively provided on both sides of the flat plate 2. Therefore, in the actual heat dissipation and cooling process… Coolant is introduced through inlet 5, flows into the flow channel, and finally flows out through outlet 6. During the flow of the coolant in the flow channel, it carries away the transferred heat, thereby playing a role in cooling and heat dissipation. In order to further enhance and optimize the local heat dissipation effect, the turbulence fins 1 are installed in the flow channel cavity to realize local turbulence of the coolant in the flow channel cavity. By changing the original laminar flow process of the coolant into local turbulent flow, the cooling effect of the coolant is enhanced, thereby improving the local heat dissipation effect.

[0017] In this embodiment, to further improve the flow-deflecting effect, the flow-deflecting fin 1 is a corrugated thin plate structure. Furthermore, the corrugated flow-deflecting fin consists of multiple unconnected, laterally placed S-shaped aluminum sheets, arranged along the coolant flow direction. The curved surface of the aluminum sheet is perpendicular to the plane of the flat plate. The thickness of the aluminum sheet is set to 0.1-0.2 mm, and its length and width can be designed according to actual needs, ensuring that the coolant flow does not affect the flow-deflecting effect. In practical applications, 3003 aluminum sheets can be used for the S-shaped aluminum sheets. Therefore, the flow-deflecting fin structure described above can further enhance the flow-deflecting effect. When the coolant flows within the flow channel, it passes through the S-shaped flow-deflecting fins, transforming from laminar flow to turbulent flow, thereby enhancing the local cooling and heat dissipation effect.

[0018] In this embodiment, to improve structural stability and facilitate installation and fixation, the turbulence fins 1 are fixed in the flow channel cavity by limiting device or spot welding.

[0019] In addition, to further improve the turbulence effect, the spacing between the multiple S-shaped turbulence fins 1 is set between 5-10mm. In practical applications, the overheating location and heat dissipation requirements of the battery cell can be identified through temperature field simulation and other methods. Then, the spacing can be further optimized as needed to achieve the maximum heat dissipation effect.

[0020] Therefore, in the actual installation and design process, based on the standardized liquid cooling plate design, the number, size, and distribution of the turbulence fins 1 are designed according to the performance parameters, size, and distribution of the battery cell module required for heat dissipation. Temperature field simulation can be performed using a standard coolant to identify overheating locations in the battery cell. Then, a fixed number of turbulence fins 1 are placed at these locations. During the sample testing phase, the position, number, and spacing of the turbulence fins are further optimized based on the actual temperature uniformity test results, and applied to the production process of the finished product, thereby enabling the finished product to achieve the required uniform temperature dissipation effect. When different battery cell module solutions need to be replaced, the above process can be followed without redesigning a new liquid cooling plate. Simply increasing or decreasing the number and distribution of the turbulence fins in certain areas can meet the heat dissipation requirements of different battery cell modules, thus offering greater practicality and flexibility while saving overall production costs.

[0021] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
