Description

Technical Field

[0001] The utility model belongs to the technical field of electric energy storage, and particularly relates to a layered overflow full-immersion energy storage box. Background Technique

[0002] At present, with the continuous improvement of China's energy consumption structure, the energy storage battery industry has shown explosive development, and the safety and stability of energy storage systems have attracted more and more attention. During the charge and discharge application of energy storage batteries, due to the existence of ohmic heat and polarization heat, a large amount of heat will be generated. If these heats cannot be diffused in time and accumulate inside the battery, on the one hand, it will cause an increase in the speed of side reactions at the interface of the energy storage battery, and on the other hand, excessive heat accumulation may cause battery thermal runaway. Therefore, efficient heat dissipation measures must be considered in the design of energy storage batteries.

[0003] At present, the heat dissipation methods of energy storage systems mainly include air cooling and liquid cooling. Among them, air cooling mainly uses air conditioners for refrigeration, the cooling medium is air, the energy efficiency ratio is low, the equipment occupies a large area, and the temperature consistency of energy storage batteries is poor. Liquid cooling uses a cooling plate with water as the cooling medium, and heat exchange occurs between the cooling medium flowing in the cooling plate and the energy storage battery. The heat needs to be transferred through the battery shell and the cooling plate and finally to the cooling medium, and then the cooling medium dissipates the heat through the radiator. Its heat transfer links are many, the thermal resistance is large, and the heat exchange efficiency is low, resulting in high requirements for the performance of the radiator.

[0004] In order to improve the heat dissipation performance of energy storage systems, an immersion energy storage system that immerses energy storage batteries in a liquid medium has developed rapidly. The immersion energy storage system immerses energy storage batteries in a liquid medium and uses heat exchange between the liquid medium and the energy storage batteries to achieve heat dissipation. However, most of the existing immersion energy storage systems adopt a static immersion method. After long-term operation, due to the gradual accumulation of heat in the liquid medium, the temperature will also gradually increase. Summary of the Invention
