Description

Technical Field

[0001] The utility model relates to the technical field of battery core equipment, in particular to a battery core heat dissipation bracket. Background Art

[0002] The heat dissipation bracket at the bottom of the battery cell usually refers to a device or structure used for heat dissipation management, which is used to effectively discharge the heat generated at the bottom of the battery cell. The bottom of the battery cell is an important heat source area inside the battery pack, because the battery cell generates heat during operation. If it cannot be discharged and dissipated in a timely and effective manner, it will cause the battery cell to overheat, affecting the performance and life of the battery, and may even cause safety problems.

[0003] The heat dissipation bracket at the bottom of the battery cell is usually made of thermally conductive materials, has good heat dissipation performance, and can effectively conduct and dissipate the heat generated at the bottom. It is usually in contact with the bottom of the battery cell, transfers the heat to the bracket, and then quickly dissipates the heat to the surrounding environment through the heat dissipation structure of the bracket. This helps to maintain a lower operating temperature of the battery cell and improve the performance and life of the battery.

[0004] In terms of thermal management of energy storage systems, battery module designs mostly use liquid cooling systems that are more expensive and complex in design. The air cooling system is gradually being replaced because its heat dissipation effect is not as good as that of the liquid cooling system. In addition, the bottom of the traditional battery cell bracket is closed, which completely wraps the bottom surface of the battery cell, which is not conducive to the heat dissipation of the battery cell. For this reason, we propose a battery cell heat dissipation bracket. Utility Model Content
