Water cooling plate unit applied to battery pack

Abstract

The invention provides a water cooling plate unit applied to a battery pack. The water cooling plate unit comprises a first plate body, a second plate body and a runner structure, wherein the first plate body and the second plate body are correspondingly covered; the runner structure is formed by a punching process and is provided with a first separation piece and a second separation piece; and the runner structure is arranged between the first plate body and the second plate body to form a channel. Therefore, the runner structure formed by the punching process can realize thinness; materials and the manufacturing cost are saved; and the heat radiation efficiency can be effectively improved when the water cooling plate unit is assembled on the battery pack.

Description

technical field [0001] The invention relates to a water-cooling plate, especially a water-cooling plate unit applied to a battery pack, which can reduce weight and achieve thinning and save material cost. Background technique [0002] In the occasions where it is currently impossible to use household AC or general DC power by wiring at any time, it is necessary to supply power by adding batteries, the most common being vehicles, lamps, power tools, electronic equipment, communication equipment or heat exchange equipment, etc. Both need to use batteries to directly or indirectly supplement the supply of electricity. [0003] During the operation of the battery pack, the battery will undergo a process of charging and discharging. During the charging and discharging process, due to the electrons running in the filling material, the temperature of the battery body will rise, and the temperature will continue to rise and exceed the working range of the battery. Temperature has a...

Problems solved by technology

[0005] The cover plate 12 also needs to be formed by CNC machining or gravity casting into a shape that can cover the separation column 111 and the base 11. Therefore, it is also necessary to use a thick plate body to complete the processing, so the water-cooled plate unit 1 The minimum thickness of the forming is 20MM, so the problem of excessive thickness and weight is caused, and the manufacturing cost of the product is high

[0006] see again Figure 1B As shown, the battery pack 2 has a plurality of batteries 21, but because the thickness of the water-cooled plate unit 1 is too thick, if it is interspersed between the batteries 21, the volume of the battery pack 2 will be too large, so the water-cooled plate unit 1 cannot Installed and interspersed between the batteries 21, the instrument can intersperse the aluminum sheets 22 between the batteries 21 and attach the batteries 21, and then attach the end edges of the aluminum sheets 22 through the water-cooled plate unit 1, so that the batteries 21 The heat generated is indirectly transferred to the water-cooled plate unit 1 through the aluminum sheet 22 attached to the surface of the battery 21, and then the heat is taken away by the water-cooled plate unit 1 to complete the purpose of heat dissipation. Efficiency is poor, and needs to utilize aluminum flake 22 to carry out heat dissipation and its whole manufacturing cost improves relatively; Therefore known technology has following shortcoming:

[0007] 1. The thickness is too thick and the weight is too heavy;

[0008] 2. High manufacturing cost;

[0009] 3. Poor cooling efficiency
