Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a multi-channel temperature control structure for energy storage batteries. Background Technology

[0002] In the field of energy storage battery pack technology, battery packs generate a large amount of heat during charging and discharging. If heat dissipation is not timely, the battery temperature can easily rise, affecting battery life, safety, and efficiency. Existing temperature control structures mostly adopt a single heat dissipation method, such as relying solely on air cooling or simple water cooling. This results in insufficient heat dissipation channels and low efficiency. Especially in rack-type structures with multiple battery packs stacked, traditional heat dissipation methods are difficult to achieve uniform and comprehensive temperature control, easily leading to localized overheating, which affects the stable operation and safety of the battery pack. Utility Model Content

[0003] To address the aforementioned technical issues, this invention presents a multi-channel temperature control system integrating circulating water cooling and auxiliary air cooling to improve the overall reliability of energy storage batteries.

The inlet of each mounting base is connected to the liquid-cooled water inlet pipe, and the outlet of each mounting base is connected to the liquid-cooled water outlet pipe. The bottom of the liquid-cooled water inlet pipe is connected to the inlet end of the liquid cooling unit via an inlet connector, and the bottom of the liquid-cooled water outlet pipe is connected to the outlet end of the liquid cooling unit via an outlet connector. The upper ends of both the liquid-cooled water inlet and outlet pipes are sealed.

[0011] Based on this, the present invention has the following beneficial effects: This invention combines the dual functions of a circulating water cooling channel and a heat dissipation window, utilizing a liquid cooling unit to rapidly circulate cold water to remove heat, supplemented by air cooling diffusion, to achieve comprehensive temperature control of multiple energy storage battery packs and avoid overheating problems.
