Liquid cooling battery cooling system

Abstract

The invention provides a liquid cooling battery cooling system and belongs to the field of liquid cooling battery cooling. The liquid cooling battery cooling system comprises a battery unit module anda cooling system shell. The battery unit module comprises a battery unit shell, a battery groove member, heat conducting glue, a battery, honeycomb fins, a cooling liquid groove and a parallel circuit. The heat generated when the battery works is fully transferred to the battery groove member through the fully-wrapped heat conducting glue, and meanwhile the temperature difference of different areas of the battery unit module can be effectively reduced, so that the battery is always in a good operating environment. The honeycomb-shaped fins are used for connecting the battery groove member with the battery unit shell so as to ensure stability; secondly, the contact area of the battery groove member and cooling liquid can be improved to the most degree, so that the heat dissipation efficiency is maximized. Liquid circulation flow is achieved through an external water pump so as to achieve the purpose of rapid heat dissipation.

Description

technical field [0001] The invention belongs to the field of heat dissipation of liquid-cooled batteries, and in particular relates to a heat dissipation system of liquid-cooled batteries. Background technique [0002] As a power battery, lithium batteries have been gradually applied to various fields of daily life. Especially in recent years, with the rise of the electric vehicle industry, the demand and application scenarios of lithium batteries have also greatly increased. The heat dissipation of lithium batteries is still a technical difficulty, which greatly affects the application of lithium batteries. [0003] The current heat dissipation methods of power batteries are mainly divided into two types: air cooling and liquid cooling: air cooling uses air as a heat transfer medium to directly let air pass through the module to achieve the purpose of cooling and heating. The wind generated by the movement of the car takes the heat of the battery away through the exhaust f...

AI Technical Summary

Problems solved by technology

However, the disadvantages of the current liquid cooling method are technical difficulty, complex structure, and high difficulty in repair and maintenance.

[0004] Among the current heat dissipation methods for power batteries, although air cooling has a simple structure and relatively small weight, its heat dissipation efficiency is low and the temperature difference between different areas of the module is large

The high heat dissipation efficiency of liquid cooling has greater development prospects in the heat dissipation of power batteries. However, the current liquid cooling heat dissipation efficiency is still not ideal, and there is still a lot of room for optimization. For example, the current liquid cooling system has a complex structure and is difficult to maintain. Especially in terms of heat dissipation contact area, there is still a lot of room for optimization
