AI Technical Summary

Technical Problem

Existing cold plates in battery packs have high heat exchange requirements due to the dense distribution of battery cells and their large weight, which increases the strength and material cost of the cold plates and also increases the manufacturing difficulty.

Method used

A reinforced cold plate load-bearing structure was designed, including a load-bearing base plate and a crossbeam assembly. The crossbeam assembly consists of left, right and middle crossbeams, and a boss is set in the cold plate mounting area to share the weight of the battery cell. The crossbeam is a one-piece molded structure.

Benefits of technology

By distributing the weight of the battery cells through the crossbeam assembly, the strength requirements of the cold plate are reduced, the cost of raw materials is reduced, and damage to the cold plate due to excessive weight of the battery cells is avoided.

BRIEF DESCRIPTION OF DRAWINGS

[0012] Fig. 1 It is the whole structure schematic diagram of the utility model.

[0013] Fig. 2 This is a schematic diagram of the structure of this utility model after the battery cell is removed. Detailed Implementation

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] Example

[0016] like Figs. 1-2 As shown, a reinforced cold plate load-bearing structure includes a load-bearing base plate 1. At least two cold plate mounting areas are provided on the end face of the load-bearing base plate 1. Cold plates 2 are installed in the cold plate mounting areas. Crossbeam assemblies are provided on the outer side and in the middle of the two cold plate mounting areas.

[0017] In this embodiment, battery cells 10 are placed on the end faces of both cold plate mounting areas.

[0018] The crossbeam assembly consists of a left crossbeam 3, a right crossbeam 6, and a middle crossbeam 7.

[0019] The left crossbeam 3 and the right crossbeam 6 are respectively provided with a first protrusion 4 and a second protrusion 5 on the inner walls near the two cold plate installation areas.

[0020] The middle crossbeam 7 is provided with symmetrical third protrusions 9 on both sides of its lower end, and the middle crossbeam 7 is arranged in a T-shape.

[0021] The left crossbeam 3, the right crossbeam 6, and the middle crossbeam 7 are all integrally formed structures.

[0022] In existing technologies, the cold plate has high heat exchange requirements and a large number of battery cells, which makes the cold plate prone to deformation under the weight of the battery cells, and the cold plate bears the weight of the battery cells alone.

[0023] The height matching between the crossbeam boss and the cold plate cell surface ensures that the cell overlaps on the crossbeam boss, thereby reducing the load on the cell surface.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
