As they have less impact on the environment than traditional vehicles, and as the requirements for energy conservation and emission reduction become increasingly stringent, the development prospects of new energy vehicles are widely optimistic.

[0003] The power of new energy vehicles is provided by the on-board power battery storage, which is required to be stable, safe and reliable. Not only does the heat released by the power battery during the energy conversion process directly affect the stability of the battery, but the low ambient temperature will also affect the conversion of battery power, resulting in a low cruising range. Using a cold plate to cool the battery is currently a common method. The function of the cold plate of new energy vehicles is to absorb the heat of the heating element and transfer it to the liquid.

[0004] With the rapid development of the modern new energy industry, the fixing methods of automotive cold plates are complex and diverse.

[0031] In the above structure, the reinforcing column 3 is a cylinder, the matching positioning hole 41 is a circular hole, and the diameter of the positioning hole 41 is larger than the diameter of the reinforcing column 3. The diameter of the positioning hole 41 only needs to be slightly larger than the diameter of the reinforcing column 3. After the reinforcing column 3 is welded to the frame 4, it is equivalent to adding a tow bar reinforcement rib to the rectangular tubular frame 4, thereby increasing the overall strength of the frame 4.

[0032] In order to facilitate processing and ensure the reliable strength of the frame 4, the plurality of reinforcing columns 3 are arranged on the same straight line along the length direction of the frame 4, and the plurality of reinforcing columns 3 are evenly spaced.

[0033] In addition, the base plate 1 is provided with a bolt hole 11, and a hexagon socket bolt 12 is provided in the bolt hole 11, and the base plate 1 is connected to the device through the hexagon socket bolt 12. When the base plate 1 is a rectangular flat plate, the four corners of the base plate 1 are provided with bolt holes 11, and the base plate 1 is installed and fixed by the hexagon socket bolts 12.

[0034] Embodiment 2

[0035] Based on the structure of the first embodiment, the substrate 1 of the utility model is a rectangular flat plate, and the substrate 1 is provided with a plurality of long positioning pins 1 5, two long positioning pins 2 6 and two short positioning pins 7. The plurality of long positioning pins 1 5, two long positioning pins 2 6 and two short positioning pins 7 surround an area with a U-shaped cross section, and the frame 4 is located in the U-shaped area surrounded by the plurality of long positioning pins 1 5, two long positioning pins 2 6 and two short positioning pins 7.

[0036] Specifically, a plurality of long positioning pins 1 5 are provided on the rectangular side opposite to the frame 4 of the substrate 1, and the plurality of long positioning pins 1 5 are arranged on the same straight line, and one of the long sides of the frame 4 abuts against the plurality of long positioning pins 1 5 to achieve positioning. Two long positioning pins 2 6 are provided on the rectangular side opposite to the frame 4 of the substrate 1, and the straight line where the two long positioning pins 2 6 are located is arranged perpendicular to the straight line where the plurality of long positioning pins 1 5 are located, and one of the short sides of the frame 4 abuts against the two long positioning pins 2 6 to achieve positioning. Two short positioning pins 7 are provided on the rectangular side opposite to the frame 4 of the substrate 1, and the straight line where the two short positioning pins 7 are located is arranged perpendicular to the straight line where the plurality of long positioning pins 1 5 are located, and the short side of the frame 4 away from the other side of the long positioning pins 2 6 abuts against the two short positioning pins 7 to achieve positioning.

The specific operation is to fix the base plate 1 to the workbench position through the hexagon socket bolt 12, put the reinforcing column 3 into the frame 4, and slide the reinforcing column 3 to the vicinity of the hole position of the frame 4 through manual operation, and then put the frame 4 on the base plate 1, close to a plurality of long positioning pins 1 5, two long positioning pins 2 6 and two short positioning pins 7, and then pop out the spring positioning pin 2, perform laser welding, and finally retract the spring positioning pin 2, lift one end of the frame 4 from the side of the short positioning pin 7, and take out the frame 4 from the short positioning pin 7.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
