The liquid metal battery heat insulation box with the air cooling heat dissipation mechanism and with the heat dissipation method thereof, disclosed by the invention, are easy to implement and the heat dissipation efficiency is high.

Description

technical field [0001] The invention relates to a liquid metal battery incubator with an air-cooled heat dissipation mechanism and a heat dissipation method thereof. Background technique [0002] Liquid metal batteries are a new type of low-cost, high-efficiency, and long-life energy storage battery technology, which has a good application prospect in large-scale energy storage in power grids. The large-capacity energy storage system composed of liquid metal batteries can adjust the peak of the power grid, load the peak and fill the valley, effectively enhance the operation stability of wind power generation and solar power generation systems, and improve the power quality. [0003] Liquid metal batteries are high-temperature batteries. The long-term operating temperature is generally 400-600°C. The working temperature for short-term heating or formation needs to reach 700°C. Therefore, the battery operation needs to have a heating and heat preservation device, and the maxim...

Problems solved by technology

First of all, the wiring of the interlayer battery pack is connected through the side, and the space utilization rate is low; secondly, the patent (application number: CN201410777993.3) emphasizes that the Joule heat of the battery itself maintains the heat supply of the incubator system under high current discharge, It may be feasible for several kilowatt-level modular incubators, but it is difficult to achieve complete self-heating of the battery pack under normal working conditions for large-scale energy storage incubators of 10 kilowatts, 100 kilowatts, megawatts and above. Especially in the initial heating stage, it is difficult to achieve heating to the target te
