[0002] Battery energy storage systems are widely used. Their core functional component is the battery module, which stores electrical energy and releases it when needed, thus achieving a cycle of operation. However, the battery module generates significant heat during charging and discharging. Excessively high temperatures can affect the cycle life and reliability of the battery module, and even pose safety risks. Therefore, cooling the battery module is essential.

[0003] Currently, liquid coolers are commonly used to cool battery modules. The cooling effect of a liquid cooler is directly related to the air volume supplied: the greater the air volume, the better the cooling effect. To quickly cool the battery module, the liquid cooler is typically operated at a high air volume, which inevitably results in high noise levels.
