The research on the heat dissipation performance of the battery pack is the current research hotspot in the electric vehicle industry. In this paper, battery modules and battery pack are simplified to heat source and semi-closed chamber, respectively.
Since the batteries in the battery pack will generate a lot of heat during operation, the performance of the battery pack will be severely affected. As a result, new energy vehicles are increasingly being developed with a focus on enhancing the rapid and uniform heat dissipation of the battery pack during charging and discharging.
Therefore, the heat dissipation performance of the semi closed chamber which is based on air cooling can directly represent the temperature distribution of the battery pack as well as its performance.
Due to the thermal characteristics of lithium-ion batteries, safety accidents like fire and explosion will happen under extreme conditions. Effective thermal management can inhibit the accumulation and spread of battery heat. This paper studies the air cooling heat dissipation of the battery cabin and the influence of guide plate on air cooling.
In addition, exchanging the air inlet and outlet can improve the synergy between the flow field and the temperature field which in turn improves the heat dissipation. The conclusion of this paper can provide a reference to the heat dissipation design of the battery pack under air cooling.
Thermal flow fields of different air outlet modes were considered in this paper, and the results show that the heat dissipation performance of air-cooled battery pack increases with the improvement of the synergy degree between velocity field and temperature gradient field.
