A direct cooling battery pack has less structural complexity and fewer auxiliary devices than indirect cooling. Hekmat et al. utilized silicone oil and PCM as a heat-conducting medium to fill between batteries and a cooling tube to cool the cells in a hybrid BTMS.
(28) The direct cooling of battery packs using refrigerants has emerged as a new cooling solution in recent years. Through experiments conducted under vehicle conditions, a comparison is made between the thermal performances of two-phase refrigerant cooling and liquid cooling with the same outer diameter.
Zhoujian et al. studied a battery thermal management system with direct liquid cooling using NOVEC 7000 coolant. The proposed cooling system provides outstanding thermal management efficiency for battery, with further maximum temperature of the battery’s surface, reducing as the flow rate of coolant increases.
(24) Scholars (25) study the collaborative heat dissipation of PCM and liquid cooling, and conclude that under the condition of an ambient temperature of 308.15 K, the temperature can be controlled at 313.15 K, and the appropriate coolant flow rate can maximize the thermal performance of the battery pack.
Even in extreme operating conditions such as a thermal runaway, direct liquid cooling has the capability to enable safe battery operation due to the high fire point and phase transition characteristics of coolants.
By changing the surface of cold plate system layout and the direction of the main heat dissipation coefficient of thermal conductivity optimization to more than 6 W/ (M K), Huang improved the cooling effect of the battery cooling system.
