In addition, the type of coolant due to the difference in thermal conductivity also affects the cooling effect of the cooling and heat dissipation system of the lithium battery pack.
A heat pipe (HP) heat dissipation model of a lithium-ion-battery pack is established for the climate in the central and southern regions in China, and the heat transfer effects of various fins with different spacing and thickness are investigated.
Xu et al. [ 36] adopted a heat dissipation method coupled with a flat HP and liquid cooling to control the temperature of the battery pack with a discharge rate of 0.5C within a stable range, but it cannot be used in the case of a high discharge rate.
Cooling effect of battery pack was improved by adjusting the battery spacings. The excessively high temperature of lithium-ion battery greatly affects battery working performance. To improve the heat dissipation of battery pack, many researches have been done on the velocity of cooling air, channel shape, etc.
The research of X.H. Hao et al. shows that the coolant temperature within a certain temperature range has a certain influence on the cooling effect of the lithium battery cooling and heat dissipation system, so the inlet coolant temperature T (K) is set as the corresponding design variable.
The staggered arrangement is more conducive to improving the heat dissipation of a battery, as it avoids the shielding of the airflow by the battery. Controlling the uniformity of the heat dissipation mode is also crucial to prevent large differences.
