Compared to natural convection and aluminum plate cooling, heat pipe cooling significantly improves heat dissipation and temperature uniformity due to its high thermal conductivity , . Integrating a flat plate Loop Heat Pipe (LHP) beneath the module in EVs marks a significant advancement in battery thermal management.
How to slow down or even prevent the spread of thermal runaway in lithium batteries is one of the unresolved safety issues in battery packs. Separating the lithium-ion battery modules with a highly efficient insulation materials layer effectively prohibits thermal runaway propagation, attracting extensive attention from many scholars.
The heat transfer is blocked by the insulation layers, and the Tpe of the next cell is slightly reduced by heat exchange with the ambient environment through radiation and convection. Thereby, it can be concluded that the addition of the insulation layers reduces the average Tpe of the battery pack which reduces the fire risks for the battery pack.
