Examples

Fig. 1 to 3 show the specific embodiment, the utility model discloses a cover plate 1, base plate 2, junction pipe 3, mounting hole 4, guiding gutter 5, vortex portion 6, base plate 2 and battery module envelope bottom direct contact, base plate 2 sets up on cover plate 1, mounting hole 4 sets up the edge at base plate 2, two junction pipes 3 and base plate 2 fixed connection, be provided with a plurality of vortex portions 6 towards base plate 2 direction arch on cover plate 1, be provided with a guiding gutter 5 towards base plate 2 direction arch on cover plate 1, the starting point position of guiding gutter 5 sets up between two junction pipes 3, the terminal point of guiding gutter 5 is not connected with the edge of cover plate 1; a coolant passage is formed between the cover plate 1 and the base plate 2, and the coolant enters and exits through two short connecting pipes 3.

In the present embodiment, the substrate 2 is disposed on the upper portion of the cover plate 1. As shown in fig. 3, the cross-sectional structure of the cover plate 1 according to an embodiment of the present invention is provided with a plurality of turbulence portions 6 on the upper surface of the cover plate 1, and the plurality of turbulence portions 6 are a plurality of protrusions arranged at intervals. The cover plate 1 is provided with a flow guide groove 5 which protrudes upwards, the starting point of the flow guide groove 5 is positioned at the edge of the cover plate 1 and is arranged between the two short connecting pipes 3, and the end point of the flow guide groove 5 is not connected with the edge of the cover plate 1. The base plate 2 is provided with a positioning hole, and the periphery of the base plate 2 is provided with a plurality of mounting holes.

In the present embodiment, the cover plate 1 and the base plate 2 are formed by brazing, a coolant channel is formed between the cover plate 1 and the base plate 2, and the coolant enters and exits through the two connecting short pipes 3. The cover plate 1 is made of an aluminum plate through stamping forming. And when the cover plate 1 is punched and formed, the size, the mounting hole 4 and the positioning hole can be determined according to the use requirement.
