Both excessive and insufficient numbers of jet pipes are detrimental to internal battery cooling. Selecting 6 jet pipes, it is evident that solely relying on either the main inlet or the jet pipe inlet for coolant cooling is far less effective than proportionally distributing flow rates between the two.

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. However, the power battery is ...

5 · Comparing to other cooling methods, liquid cooling has received considerable attention due to its excellent cooling efficiency and heat dissipation [11], [12].Based on the type of contact between the battery and the liquid, liquid cooling is divided into two types: indirect liquid cooling and direct liquid cooling (also known as immersion liquid cooling).
Substantial efforts have been devoted to developing various BTMS. These can be divided into active and passive methods, including forced air cooling (FAC) [6, 7], heat pipe cooling [8], phase change material (PCM) cooling [9, 10], direct liquid cooling [[11], [12], [13]], and a combination of these technologies [14].FAC is the first choice for battery cooling owing to its …
