Description

Technical Field

[0001] The utility model relates to the technical field of energy storage battery insertion boxes, in particular to a liquid-cooled energy storage insertion box. Background Art

[0002] With the development of the current energy storage industry, lithium battery energy storage has been widely used in power grid frequency modulation, microgrids, and industrial and commercial energy storage. However, most of the current market uses natural cooling or air cooling, which cannot meet the development needs of the system for large capacity and high rate. At the same time, temperature has a great impact on the safety and service life of the battery system. Too high temperature and too large temperature difference seriously affect the service life of the battery. In severe cases, there are safety risks, which may cause the battery to experience thermal runaway, and then cause safety accidents such as fires and explosions. Therefore, there is an urgent need for a heat management structure that can quickly and evenly dissipate heat and is safe to manage the battery temperature field.

[0003] In the prior art, patent (CN219371129U) mentions a liquid-cooled energy storage insertion box, including a box body and a battery cell group; the number of battery cell groups is multiple, and multiple battery cell groups are placed in the box body. A liquid-cooled plate is provided between two adjacent battery cell groups. The liquid-cooled plate is vertically arranged, and a liquid-cooling cavity and a closed cavity are arranged in the liquid-cooled plate. One end of the liquid-cooled plate is provided with a liquid inlet and a liquid outlet communicating with the liquid-cooling cavity. The closed cavity is filled with a fire extinguishing agent, and the end of the closed cavity is provided with a cover. The material of the cover is a heat-shrinkable material; two circulation pipe orifices are provided on the outer side of the box body, and the liquid inlet and the liquid outlet are respectively connected to the two circulation pipe orifices through connection components. This prior art can quickly and evenly dissipate heat from the battery cells through the liquid-cooled plate. When a battery cell experiences thermal runaway, the temperature at the cover exceeds the threshold value. Under the condition of high-temperature heating, the cover quickly shrinks, destroys the sealing interface, and instantly releases the internally encapsulated fire extinguishing agent to fill the entire battery box body, preventing the battery from burning quickly and buying precious time for personnel evacuation.

[0004] In the above prior art, by arranging a liquid-cooled plate between two adjacent battery cell groups, the area covered by a single liquid-cooled plate is small, and the heat dissipation is poor. Summary of the Utility Model
