Description

Technical Field

[0001] This utility model belongs to the field of automotive battery technology, specifically relating to a battery direct cooling plate structure. Background Technology

[0002] The electricity in new energy vehicles is provided by onboard power batteries, which require stability, safety, and reliability. Not only does the heat released during energy conversion directly affect battery stability, but excessively low ambient temperatures can also impair battery power conversion, leading to reduced driving range. Therefore, temperature control of power batteries is crucial.

[0003] Currently, all components of products on the market are made of aluminum and fixed by brazing. Brazing is polluting and requires a brazing drying tunnel, which is costly, requires a large equipment area, and has a long production cycle. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a direct cooling plate structure for batteries that is easy to process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery direct cooling plate structure, comprising an aluminum plate, wherein a first connector and a second connector are fixedly connected to the outer walls of both sides of the aluminum plate, and the first connector and the second connector are fixed to the two sides of the aluminum plate by plastic coating; a flow guide is welded to the outer wall of the first connector, a first sealing cap is welded to the outer wall of the flow guide, a second sealing cap is welded to the outer wall of the second connector, and a metal part is fixed to the inner wall of the flow guide by plastic coating.

[0006] The above technical solution offers the advantage of easy processing. The first and second connectors are fixed to both sides of the aluminum plate by plastic coating. Compared with the traditional brazing process, there is no need for a brazing oven, which will not cause brazing pollution, reduce costs, and reduce the area occupied by the production equipment. At the same time, the first and second sealing caps are also easy to fix to the plastic first and second connectors.

[0007] Preferably, the flow guide includes a connector, one outer wall of which is connected to an inlet and the other outer wall of which is connected to an outlet. The inner wall of the connector has a flow channel, and the inlet is positioned higher than the outlet.

[0008] The above technical solution can achieve the function of heat dissipation. The coolant can enter the aluminum plate through the inlet, and then the flowing coolant absorbs heat from the aluminum plate. Finally, the coolant is discharged through the outlet, thereby cooling the aluminum plate.

[0009] Preferably, the aluminum plate has hollow channels inside, and the channels are multi-layered.

[0010] The above technical solution can achieve rapid heat absorption. The multi-layered structure of the pipe can increase the contact area between the coolant and the aluminum plate, thereby increasing the heat absorption rate and improving the heat dissipation effect.

[0011] Preferably, the inner wall of the first connector is divided into upper and lower sections, with the upper section connected to the inlet and the lower section connected to the outlet.

[0012] The above technical solution can play a guiding role. By separating the first connecting part into upper and lower sections, the flow direction of the coolant can be clearly defined, thereby playing a guiding role.

[0013] Preferably, the aluminum plate is divided into upper and lower sections by the first connector, and the upper and lower sections are connected at the second connector.

[0014] The above technical solution can play a guiding role. By separating the aluminum plate into upper and lower sections through the first connector, the flow direction of the coolant can be clearly defined, thereby playing a guiding role.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The first and second connectors are fixed to both sides of the aluminum plate by plastic coating. Compared with the traditional brazing process, there is no need for brazing oven, which will not cause brazing pollution, reduce costs, and reduce the area occupied by the production equipment. At the same time, the first and second sealing caps are also easy to fix to the plastic first and second connectors.

[0016] 2. The coolant can enter the aluminum plate through the inlet, and then the flowing coolant absorbs heat from the aluminum plate. Finally, the coolant is discharged through the outlet, thus cooling the aluminum plate. Attached Figure Description
