Description

Technical Field

[0001] The utility model relates to the technical field of battery energy storage and heat dissipation, in particular to a high-efficiency heat dissipation system for an energy storage battery. Background Art

[0002] High-efficiency energy storage batteries are also called high-efficiency energy storage systems. The most common high-efficiency energy storage batteries are lead-acid batteries. Currently, lithium-ion energy storage batteries with lithium iron phosphate as the positive electrode material are being gradually developed. High-efficiency energy storage systems will generate a lot of heat during operation. Most of the current high-efficiency energy storage systems are not easy to dissipate heat efficiently during use, which makes it easy for the high-efficiency energy storage systems to have their service life greatly reduced due to high temperatures.

The heat dissipation mechanism facilitates the heat dissipation of the heat generated during the operation of the battery cells, thereby improving the service life of the efficient energy storage system. However, the above scheme only conducts heat to the battery cells through a heat conducting plate and a heat conducting silicone pad. When the external ambient temperature is high, the heat conduction effect is greatly reduced, affecting the use of the battery cells. Utility Model Content
