Heat Dissipation Analysis on the Liquid Cooling System Coupled with a Flat Heat Pipe of a Lithium-Ion Battery.

The liquid-cooled thermal management system based on a flat heat pipe has a good thermal management effect on a single battery pack, and this article further applies it to a power battery system to verify the thermal management effect. The effects of different discharge rates, different coolant flow rates, and different coolant inlet temperatures on the temperature distribution uniformity of the power battery system were analyzed, and the effectiveness of the flat heat pipe in improving the thermal equilibrium performance of the liquid-cooled thermal management system was verified.
