AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively prevent the transfer of secondary batteries during charging or operation due to thermal expansion or fire, and their cooling efficiency is inadequate, resulting in poor safety and energy efficiency.

Method used

The liquid immersion cooling module utilizes buffer components and a fracture membrane structure to form a buffer space on the cell stack surface, using cooling fluid for cooling. When the cell expands, the fracture membrane allows the cooling fluid to flow into the buffer space, blocking heat transfer and fire spread.

Benefits of technology

It improves the cooling efficiency of the battery module, effectively prevents thermal expansion and fire, extends the service life of the device, reduces carbon emissions, and improves energy efficiency.

Abstract

A liquid immersion cooling module according to one embodiment of the present disclosure includes a case in which a cooling fluid is contained, and a battery module immersed in the case, the battery module can include a buffer member formed at a cell and a stacking surface of the cell, and internally formed with a buffer space blocking inflow of the cooling fluid by a rupture film. According to one embodiment of the present disclosure, there is an effect that the battery module can be immersed in the cooling fluid to improve cooling efficiency, and can effectively buffer physical deformation such as thermal expansion of each cell of the battery module.
