Battery module liquid-cooling device

Abstract

The invention relates to a battery module liquid-cooling device comprising a battery module and a water tank; the battery module comprises a shell body, an electrical core bracket, electrical cores, heat dissipation aluminum tubes, a copper current-carrying piece, an insulation board, a fixed steel frame and threaded rods; the electrical cores are arranged in the shell body in a multi-layer stacking manner, and one heat dissipation aluminum tube is arranged between each four electrical cores distributed in a shape like a Chinese character 'tian'; the water tank comprises a tank body; the tank body is provided with a plurality of heat dissipation aluminum tube inserting holes, each heat dissipation aluminum tube inserting hole is provided with an inserting groove, and the inserting grooves are formed in the inner wall of the tank body, the shape of the inserting grooves is matched with the shape of heat exchange ends of the heat dissipation aluminum tubes, and the number and distribution of the heat dissipation aluminum tube inserting holes are the same as those of the heat dissipation aluminum tubes; the device has the advantages of good heat dissipation effect, low cost, high sealing grade, and high safety.

Description

technical field [0001] The invention relates to a liquid cooling device, in particular to a battery module liquid cooling device. Background technique [0002] At present, there are many heat dissipation solutions for battery packs, such as natural cooling, air cooling, liquid cooling, etc. [0003] 1. Natural cooling is to dissipate heat from the battery pack through the wind generated during the driving process of the car. The effect is not obvious, especially in hot areas, and it has little effect. [0004] 2. The air-cooling system uses the wind from the air conditioner to dissipate the heat inside the battery pack. However, there must be vents, so that the sealing level of the battery pack cannot reach IP67, and the safety will be reduced. [0005] 3. The effect of the liquid cooling system is the best. The cost of the entire cooling system is relatively expensive. The existing liquid cooling system requires liquid to enter and exit, the sealing level will also decreas...

Problems solved by technology

[0003] 1. Natural cooling is to dissipate heat from the battery pack through the wind generated during the running of the car, the effect is not obvious, especially in hot areas, it has little effect

[0004] 2. The air-cooling system uses the wind from the air conditioner to dissipate heat inside the battery pack. However, there must be vents, so that the sealing level of the battery pack cannot reach IP67, and the safety will be reduced.

[0005] 3. The effect of the liquid cooling system is the best. The cost of the entire cooling system is relatively expensive. The existing liquid cooling system requires liquid to enter and exit, and the sealing level will also decrease, and the safety is low.
