Description

Technical Field

[0001] The utility model relates to the technical field of thermal management of power batteries, in particular to a cold plate with a self-contained protective buffer structure. Background Art

[0002] With the continuous updating of power battery structure, the connection and fixing method between battery cold plate and battery tray is also constantly updated and adjusted. The protective connection of the bottom guard plate will be connected to the cold plate. Therefore, if the connection point is at the non-flow channel cavity of the cold plate, the installation and fixing position can be set on the welding surface of the flat plate and the flow channel plate. If the connection point is above the flow channel cavity, the connection and fixing position will directly contact the flow channel cavity, which will cause the flow channel cavity to be squeezed when the connection and fixing position is subjected to force, causing the flow channel cavity to be affected, such as Figure 7 As shown, the performance of the product is affected. In addition, there is no protective structure on the side of the flow channel plate of conventional products. If liquid is stored at the bottom, the flow channel plate will be corroded.

[0005] As a preferred technical solution of the utility model, the flow channel includes a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are connected to a cooling circulation system to achieve heat exchange of the flow channel.

[0006] As an optimal technical solution of the utility model, a positioning groove is provided at the edge of the upper surface of the cold plate, and a positioning boss is provided at the bottom of the profiling plate. The positioning boss cooperates with the positioning groove, and preliminary fixation is performed by the positioning boss and the positioning groove to facilitate welding between the profiling plate and the cold plate.

[0007] As a preferred technical solution of the utility model, the four sides of the profiling plate are in contact with the four sides of the outer side of the flow channel, and the profiling plate is used to wrap and protect the flow channel.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model wraps the flow channel through the wrapping groove of the contoured plate to prevent the flow channel from being directly hit by external objects, and the convex bump, the reinforcing column and the reinforcing ribs are used to make the connecting column have better cushioning and better rigidity, so when the bottom guard plate is subjected to external force, the flow channel is prevented from being squeezed, causing deformation or leakage of the flow channel.
