Technical Field

[0002] In today's society, with the rapid development of science and technology, batteries, as a key energy storage device, play a vital role in various fields, especially in the fields of electric vehicles, energy storage systems, aerospace, and portable electronic devices. However, batteries generate a lot of heat during operation. Excessive temperature will not only affect battery performance and life, but may even cause safety problems, such as thermal runaway. Therefore, how to effectively control and manage the operating temperature of the battery has become an important topic in the research and development of battery technology. The circulating cooling battery compartment component came into being in this context. It is an efficient heat dissipation device designed for battery thermal management needs. This component mainly combines the battery pack and the cooling system organically through an integrated design to achieve dynamic and precise temperature control of the battery system.

By surrounding the cooling plate between the battery packs, the plurality of battery packs are separated, and the heat accumulation generated by the battery packs is reduced. At the same time, the water cooling liquid is circulated in the cooling plate through the connection ports at both ends of the cooling plate, so as to perform heat exchange on the battery packs, and effectively improve the heat dissipation effect.
[0004] However, when the above device is used, due to the large number of heat dissipation points in the battery pack, the above device will cause the battery to have a temperature gradient distributed from the middle to the two ends, making the temperature in the middle of the battery pack too high, which will greatly affect the charging and discharging efficiency of the battery, thereby limiting the discharge power of the battery and affecting the use of the battery pack. Therefore, it is necessary to propose a circulating cooling battery compartment component. Utility Model Content
