The air-cooled battery cabinet and the liquid-cooled battery cabinet are two battery energy storage systems with different heat dissipation methods, and they have significant differences in heat dissipation principles, advantages and disadvantages, and application scenarios. Principle of the air-cooled battery energy storage system: Air-cooled heat dissipation is a thermal management technology extended from air-conditioning technology. By mechanical means such as a fan, a low-temperature medium is sent into the system, and the medium flows through the battery surface, and the heat generated by the battery is taken away by two methods of heat conduction and heat convection. Characteristics: Air-cooled heat dissipation has the advantages of mature solution, simple structure, easy maintenance, low cost, etc., and is suitable for occasions with a low heat generation rate. Principle of the liquid-cooled battery energy storage system: The liquid-cooled energy storage battery cabinet adopts liquid-cooled technology, and the heat is transferred to the cooler through equipment such as heat pipes and circulation pumps for heat dissipation, so as to realize the cooling of energy storage components. Characteristics: The liquid-cooled technology can effectively cool the energy storage components, reduce the temperature of the system, and extend the service life; it can quickly respond to peak loads and meet the energy storage requirements of high-frequency and high-power battery packs. However, the equipment manufacturing cost is high, the installation and maintenance are difficult, and the problems of noise and pollution are more prominent.
