Battery module

Battery module with refrigerant convection heatsinks and heat dissipation via condensation and evaporation

This technology is a thermal management mechanism that efficiently dissipates heat from battery cells by placing heatsinks with circulating refrigerant between the cells and repeating the condensation and evaporation process through cooling members connected to external cooling channels.

Conventional methods cool only one side of the battery cell, leading to significant temperature variations within the cell, which results in degraded performance and a shortened lifespan.

This technology inserts U-shaped or ring-shaped heatsinks, where refrigerant circulates, between battery cells. By bringing the condensation section of the heatsink into contact with a cooling member to condense the refrigerant, and the evaporation section into contact with the cell surface to utilize the heat of vaporization for effective heat dissipation, this design has broad applications in the research and development of battery thermal management and safety systems.
