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.
Also, not much research has been done on the combination of two liquid cooling systems or a hybrid liquid cooling system, and this is one of the growing topics in the field of battery thermal management systems, and the innovative channel designed in this study is related to this.
Conclusions The direct liquid cooling technique offers a considerable advantage by delivering a higher heat removal rate than other cooling methods for lithium-ion battery packs. Nevertheless, this cooling method has a significant issue during battery cells' high discharge current rates.
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.
Recently, the direct liquid-cooling technology for battery thermal management has received significant attention. The heat generated from the battery is absorbed directly by sensible (single-phase) cooling or latent heat (two-phase) cooling of the liquid with no thermal contact resistance.
Four cooling strategies were compared: natural cooling, forced convection, mineral oil, and SF33. The results demonstrate that SF33 immersion cooling (two-phase liquid cooling) can provide a better cooling performance than air-cooled systems and improve the temperature uniformity of the battery.

At pack level, temperature homogeneity must also be sought. Liquid cooling systems attract a lot of attention, as seen in [6] who documented the water-cooled BTMS performance of a 20 Ah prismatic Li-ion battery cell under 1C and 4C discharging conditions. The experiments were performed with high conductive dual cold plates having nine inlets and outlets.
For example, contacting the battery through the tube and the flow of the liquid among the tube, and exchanging energy between the battery and the liquid through pipe and other components [9]. ICLC is currently the main thermal transfer method for liquid cooling BTMS due to its compactness and high efficiency [ 152, 153 ].
