[0032] Further, at least two support beams 1 are arranged in parallel along the length direction of the liquid cooling plate 100.

[0033] Further, the depth of the groove 3 is the same as the height of the fluid channel 102 of the liquid cooling plate 100.

[0034] Furthermore, both ends of the support beam 1 are fixed to the frame 4.

[0035] Furthermore, a reinforcing plate 5 is arranged inside the support beam 1. The reinforcing plate 5 includes a bottom plate 51 and first bumps 52 and second bumps 53 which are fixedly arranged on the upper surface of the bottom plate 51 in a staggered manner. The bottom plate 51 is fixedly arranged on the bottom surface of the support beam 1;

[0036] The upper end surface of the first bump 52 is fixedly connected to the lower end surface of the lower plate 101 of the liquid cooling plate 100, and the upper end surface of the second bump 53 is fixedly connected to the lower part of the fluid channel 102 of the liquid cooling plate 100.

[0037] Furthermore, cavities are formed inside the first bumps 52 and the second bumps 53, and through holes 54 are formed in the bottom plate 51 at positions corresponding to the first bumps 52 and the second bumps 53. The through holes 54 are communicated with the cavities of the first bumps 52 and the second bumps 53.

[0038] Furthermore, the first bumps 52, the second bumps 53 and the bottom plate 51 are integrally formed by stamping.

[0039] Furthermore, the connecting plate 2 is fixedly connected to the bottom surface of the lower plate of the liquid cooling plate 100 by welding or riveting.

[0040] Furthermore, the support beam 1 and the reinforcing plate 5 are made of aluminum alloy materials.

[0041] The working principle of the above technical solution: The application of power batteries is becoming more and more extensive. Heat will be generated during the charging and discharging process. The battery packs of power batteries now mostly use the liquid cooling plate 100 for cooling to ensure the normal operation of the power battery. The liquid cooling plate 100 includes an upper plate and a lower plate 101. A downwardly convex fluid flow channel 102 is arranged on the lower plate 101. The liquid flowing in the fluid flow channel 102 takes away the heat generated by the battery pack in contact with the upper plate of the liquid cooling plate 100.

[0042] On the upper end faces of two longitudinal plates 11 of the U-shaped support beam 1, a plurality of connecting plates 2 are symmetrically and fixedly arranged. The connecting plates on the two longitudinal plates 11 are symmetrically arranged with the vertical plane passing through the U-shaped center line of the support beam 1 as the symmetry plane. The connecting plate 2 is a horizontally arranged L-shaped plate, including a short plate 23 and a long plate 24. The L shape formed by the short plate 23 and the long plate 24, the short plate 23 is vertically arranged, the lower end face of the short plate 23 is fixedly arranged with the upper end face of the longitudinal plate 11 of the support beam 1, the long plate 24 is horizontally arranged, and the long plate 24 is located outside the two longitudinal plates 11 of the U-shaped support beam 1. A groove 3 is formed between adjacent connecting plates 2. The connecting plate 2 is fixedly arranged on the lower plate of the liquid cooling plate, between the fluid flow channels 102. The connecting plate 2 is directly welded or riveted to the liquid cooling plate. The groove 3 is used to support the fluid flow channels 102 at the lower part of the liquid cooling plate. The first connecting plates 21 at both ends of the support beam 1 are fixedly connected to the edge of the liquid cooling plate, and their widths are wider, larger than the second connecting plates 22 in the middle of the support beam. At least two support beams are arranged along the length direction of the liquid cooling plate 100. Both ends of the support beam 1 are respectively fixed on the frame 4, and the frame 4 plays a role in fixing and supporting the support beam.

[0043] Reinforcing plates 5 are arranged inside the support beam 1. The reinforcing plate 5 includes a bottom plate 51 and first convex blocks 52 and second convex blocks 53 arranged in a staggered manner on the upper surface of the bottom plate 51. The bottom plate 51 is fixedly arranged on the bottom surface of the support beam 1. The upper end face of the first convex block 52 is fixedly connected to the lower end face of the lower plate 101 of the liquid cooling plate 100. The upper end face of the second convex block 53 is fixedly connected to the lower part of the fluid channel 102 of the liquid cooling plate 100. Reinforcing ribs are arranged between adjacent first convex blocks 52 and second convex blocks 53. The height of the first convex block 52 is greater than the height of the second convex block 53. The first convex block 52 is aligned with the position of the connecting plate 2 of the support beam, and the second convex block 53 is aligned with the position of the groove 3.

[0044] Through holes are opened on the bottom plate 51 and cavities are arranged in the first convex blocks 52 and the second convex blocks 53. In order to reduce the weight of the reinforcing plate 5, the first convex blocks 52, the second convex blocks 53 and the bottom plate 51 can be integrally formed by stamping.

[0045] Compared with the traditional wavy reinforcing beam, the first convex blocks 52 and the second convex blocks 53 with cavities have higher compressive strength and better stability. Reinforcing ribs are arranged between adjacent first convex blocks 52 and second convex blocks 53, increasing the overall compressive strength of the reinforcing plate 5.

[0046] The support beam 1 and the reinforcing plate 5 are made of aluminum alloy material, and the aluminum alloy material has high strength and light weight.

[0047] The beneficial effects of the above technical solutions:

[0048] The structure for improving the bearing capacity and compressive deformation of the liquid cooling plate according to the present utility model fixedly connects a support beam to the lower part of the liquid cooling plate, increasing the yield strength of the liquid cooling.
