Description

Technical Field

[0001] This utility model relates to the field of automotive battery heat dissipation and technology, specifically to a porous bent flat tube heat exchanger assembly. Background Technology

[0002] As the market demand for liquid-cooled plates in the new energy industry increases, the safety performance of new energy power batteries is receiving more and more attention. Currently, new energy power battery packs typically use flat tube heat exchangers for heat dissipation. However, due to the close arrangement of the batteries within the battery pack, the existing flat tube heat exchanger structure leads to an imbalance in battery temperature across different parts of the pack. The temperature of the batteries in the middle is much higher than that of the surrounding batteries. This not only fails to effectively solve the battery heat dissipation problem but also seriously affects the battery performance and lifespan due to uneven battery temperature. Utility Model Content

[0003] The purpose of this invention is to provide a porous bent flat tube heat exchanger assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a porous bent flat tube heat spreader assembly, comprising a bent flat tube, wherein the bent flat tube is sequentially provided with a water-cooling connector, a sealing plate and a plug, and the middle area of ​​the bent flat tube is a battery pack installation area.

[0005] In a further optimized version, the sealing sheet is made of aluminum and its surface is coated with flux.

[0006] In a further optimized configuration, the water-cooled connector and the sealing plate are connected by brazing after assembly.

[0007] In a further optimized configuration, the water-cooled connector, sealing plate, bent flat tube, and plug are laser-welded together after assembly.

[0008] Further optimized, the bent flat tube is formed by die extrusion and is an internally hollow profile flat tube formed by bending process.

[0009] Beneficial effects

[0010] The porous bent flat tube heat exchanger assembly provided by this utility model is based on a water-cooled plate assembly with porous flat tubes arranged at the bottom and middle of the battery. By setting multiple parallel flow channels in the flat tube to circulate coolant, the problem of battery heat dissipation can be effectively solved, and the problem of uneven battery heat dissipation can also be solved. The flat tube adopts a bending process, which is simpler in structure than the traditional flat tube water-cooled plate, and has a larger heat dissipation area and higher heat dissipation efficiency.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] Example

[0016] like Figure 1-3 As shown, a porous bent flat tube heat exchanger assembly is characterized by comprising a bent flat tube 3, wherein the bent flat tube 3 is provided with a water-cooling connector 1, a sealing plate 2 and a plug 4 in sequence, and the middle area of ​​the bent flat tube 3 is a battery pack installation area 5.

[0017] In this embodiment, the sealing piece 2 is made of aluminum and its surface is coated with flux.

[0018] The water-cooled connector 1 and the sealing plate 2 are connected by brazing after assembly.

[0019] The water-cooled connector 1, sealing plate 2, bent flat tube 3, and plug 4 are assembled and then laser-welded together.

[0020] The bent flat tube 3 is a hollow profile flat tube formed by die extrusion and bending process.

[0021] It can achieve double-sided heat dissipation of a single cold plate, and the battery module can be attached to both sides of a single plate through a bent flat tube solution, resulting in a large heat dissipation area and higher heat dissipation efficiency in a limited space.

[0022] By using a combination of sealing plates and flat tube parallel flow channels, the uniformity of flow distribution is ensured, while the battery temperature is more uniform, effectively improving battery performance and lifespan.

[0023] The assembly process is simple, reducing production links and operation steps, making the production process smoother, thereby improving production efficiency and reducing enterprise manufacturing costs.

[0024] The water-cooled connector achieves vertical flow separation after being brazed with the sealing plate. The flat tube is bent and extruded through a mold to obtain a hollow profile flat tube. Then, it is made into a bent flat tube through a bending process and assembled with the welded water-cooled connector and sealing plate.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
