To verify the effectiveness of the cooling function of the liquid cooled heat dissipation structure designed for vehicle energy storage batteries, it was applied to battery modules to analyze their heat dissipation efficiency.
Basu et al. designed a cooling and heat dissipation system of liquid-cooled battery packs, which improves the cooling performance by adding conductive elements under safe conditions, and the model established by extracting part of the battery temperature information can predict the temperature of other batteries.
The battery liquid cooling heat dissipation structure uses liquid, which carries away the heat generated by the battery through circulating flow, thereby achieving heat dissipation effect (Yi et al., 2022).
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.
Satyanarayana et al. (Satyanarayana et al., 2023) examined the cooling effects of natural air cooling, forced air cooling and immersion liquid cooling on battery modules, and the results demonstrated that only immersion liquid cooling could meet the heat dissipation requirements of the battery module under high-rate cycling circumstances.
Discussion: The proposed liquid cooling structure design can effectively manage and disperse the heat generated by the battery. This method provides a new idea for the optimization of the energy efficiency of the hybrid power system. This paper provides a new way for the efficient thermal management of the automotive power battery.
