By preventing excessive heat buildup, this cooling system significantly reduces the risk of battery fires and the release of toxic gases, thereby enhancing the safety of both the vehicle and its occupants. Another aspect of user safety is battery cell containment.
In the battery cooling system, early research used a combination of heat pipes and air cooling. The heat pipe coupled with air cooling can improve the insufficient heat dissipation under air cooling conditions [158, 159, 160, 161], which proves that it can achieve a good heat dissipation effect for the power battery.
In air convection cooling, the low thermal conductivity and low specific heat capacity of air prevent it from lowering the maximum temperature and maintaining a uniform temperature in the battery pack when there is a lot of heat . However, battery performance is closely related to temperature .
The contact area of the cylindrical battery outer surface is small. Providing a cooling system on the outer surface will result in a large temperature gradient and a higher hot spot temperature inside the battery. Accelerating the battery aging, and reduce the performance.
Yu et al. developed a three-stack battery pack with the stagger-arranged Lithium-ion battery cells on each stack with two options: natural air cooling and forced air cooling as shown in Fig. 2. The experimental results showed that the active air cooling method could reduce the maximum temperature significantly. Fig. 2.
Some scholars have adopted the coupling of flat heat pipes and air cooling and found that the effect of heat pipe coupling with forced air cooling is better , but there are cases where the cooling rate of the battery gradually decreases with the increase of air speed .
