Since most of the power sources of new energy vehicles are lithium iron phosphate or ternary batteries, while the power battery provides power for new energy vehicles, the battery itself emits a lot of heat, which will increase the temperature of the power battery.
In the case of the liquid cooling plates and serpentine bends we have at Trumonytechs, for example, in indirect contact liquid cooling, the fluid flows inside the pipe and comes into direct contact with the battery through the thermal conductivity interface material, for example, transferring heat through the thermal conductivity interface material and cooling the battery by transporting it through the fluid flow heat exchanger.
Cooling systems based on liquid heat exchange are more efficient than air systems and have a more uniform temperature inside the battery pack of an electric vehicle, but the systems are more complex.
