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.
Experimental setup The experimental apparatus of the liquid immersion cooling battery pack was shown in Fig. 14, which primarily consisted of three parts: the circulation system, heating system, and measurement system. The coolant was YL-10 and it exhibited excellent compatibility with all the materials and devices used in this experiment.
The findings demonstrate that a liquid cooling system with an initial coolant temperature of 15 °C and a flow rate of 2 L/min exhibits superior synergistic performance, effectively enhancing the cooling efficiency of the battery pack.
The temperature difference of the battery pack could reach 2.58 °C at a gradient angle increment of 15° and an inlet velocity of 0.015 m/s. Zhou et al. proposed a liquid cooling method based on a semi-helical conduit for cylindrical lithium-ion batteries.
A power battery pack is composed of 10 lithium-ion power battery cells, and the arrangement is shown in Fig. 2. The volume of the box is 180 mm × 140 mm × 247 mm, and there is a 5-mm gap between the battery and the battery. The geometric modeling of the whole battery cooling system was established by the SCDM software.
Feng studied the battery module liquid cooling system as a honeycomb structure with inlet and outlet ports in the structure, and the cooling pipe and the battery pack are in indirect contact with the surroundings at 360°, which significantly improves the heat exchange effect.
