[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments.
[0023] With reference to Figures 1-7 The utility model discloses a liquid cooling battery heat dissipation frame, including frame body 1 and battery pack 4, frame body 1 includes two vertical parallel square steel 11 and two C type steel 12 group, be provided with multilayer cold plate 2 on frame body 1, and the left and right sides of cold plate 2 on frame body 1 are provided with U type bending plate 13, and the front and rear sides of cold plate 2 are provided with beam 14.

[0025] Among them, square steel 11 and C type steel 12 all are fixedly connected through multiple beam 14, and the lower of beam 14 end is fixedly provided with angle support plate 16. Through the setting of angle support plate 16, can further improve the carrying capacity of beam 14, to improve the overall stability of frame body 1 in the use process.
[0026] Among them, the left and right sides of the bottom of cold plate 2 all are fixedly connected with U type bending plate 13, and the front and rear sides of the bottom of cold plate 2 all are fixedly connected with beam 14.
[0027] Among them, the two sides of cold plate 2 close to beam 14 all are provided with U type ring 21, and the other two sides of cold plate 2 all are provided with plug strip 23. Because flow channel plate 24 is integrally formed profile, therefore under the condition of guaranteeing strength, need to reduce weight properly, so part thicker plate material in cold plate 2 will adopt the structure of internal hollowing. Part adopts U type ring 21 and decorates, and the place of bolt fastening also needs to use U type ring 21 and assist fastening, so that can guarantee that bolt locking does not let the plate material produce deformation under the condition of plate material internal hollowing, to enhance the strength of plate material.

[0033] Further, in the technical solution, the cold plate 2 is not integrated with the battery pack 4, so no matter what different parameters the battery pack 4 has, the cold plate 2 is always the same, and the liquid cooling pipeline 3 does not need to be custom-made according to the different parameters of the battery pack 4.
[0034] Further, the liquid cooling pipeline 3 can also be hidden in the steel groove of the C-shaped steel 12 through the unique inner groove feature of the C-shaped steel 12, and the main pipeline of the liquid cooling pipeline 3 can be placed below the battery rack to hide the liquid cooling inlet and outlet connector pipeline in the cold plate 2.
[0035] In the utility model, through the cold plate 2 and the liquid cooling pipeline 3 on the frame body 1, heat exchange of the battery pack 4 on the cold plate 2 can be realized to dissipate heat of the battery pack 4.
