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.
This report investigates the thermal performance of three liquid cooling designs for a six-cell battery pack using computational fluid dynamics (CFD). The first two designs, vertical flow design (VFD) and horizontal flow design (HFD), are influenced by existing linear and wavy channel structures.
The objective of the project was to develop and evaluate the effectiveness of liquid cooling structures for thermal management within a battery pack. As identified in the literature, liquid cooling surpassed air cooling in terms of heat capacity and heat transfer efficiency, making it the chosen method for the investigation.
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.
In recent years, the effective heat dissipation methods for the lithium-ion battery pack mainly include air cooling , liquid cooling [13, 14], phase change material cooling , and heat pipe cooling [16,17].
Currently, the heat dissipation methods for battery packs include air cooling , liquid cooling , phase change material cooling , heat pipe cooling , and popular coupling cooling . Among these methods, due to its high efficiency and low cost, liquid cooling was widely used by most enterprises.
