Integrated direct-current energy storage and heat dissipation system

Abstract

The invention discloses an integrated direct-current energy storage heat dissipation system which comprises a container, and an energy storage PCS inverter, an energy storage battery and a power distribution cabinet which are arranged in the container. A multi-stage partition heat dissipation system is arranged in the container and divides the interior of the container into a front-end heat dissipation area, a middle heat dissipation area and a rear-end heat dissipation area. The multi-stage partition heat dissipation system comprises a first temperature sensor, a first air convection circulating fan, a first mounting base and a first rotating table which are arranged in the front-end heat dissipation area, and further comprises a second temperature sensor, a second air convection circulating fan, a second mounting base and a second rotating table which are arranged in the middle heat dissipation area, and further comprises a third temperature sensor, a third air convection circulating fan, a third mounting base and a third rotating table which are arranged in the rear end heat dissipation area, and a temperature displayer for displaying the temperature of the front end heat dissipation area, the temperature of the middle heat dissipation area and the temperature of the rear end heat dissipation area at the same time is arranged at the front side of the container.

[0002] The containerized energy storage system concentrates all the components of the energy storage system in one or more standard containers, which has the advantages of less land occupation, easy installation, and mobility. Significantly reduce the impact of new energy power generation on the grid and improve the utilization rate of new energy. At the same time, the energy storage system can also provide inertial damping to provide reliability of negative charge power supply. Therefore, there are currently DC energy storage systems on the market, but due to the The internal components of the system are highly integrated, and the heat dissipation space is limited. In the case of outdoor use without shelter, the temperature inside the sealed cabinet may exceed the allowable range of the equipment due to the sunlight radiation and the heat dissipated by the electronic equipment itself. Operation under overload and high temperature will cause the performance of components to degrade, which will lead to device failure and affect the stability of the DC energy storage system. Therefore, it is urgent to design a cooling system integrated with the DC energy storage system to ensure the safety of the DC energy storage system. , stable operation
