Customer Service(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.
Although refrigerant cooling has a strong cooling capacity and is less affected by ambient temperature, the working process of the system consumes a high amount of energy. In conditions of low environment temperature or minimal battery cooling requirements, using refrigerant cooling may result in a rapid decrease in battery temperature.
Based on a comprehensive review and summary, the design and application of a battery thermal management system (BTMS) based on refrigerant cooling with refrigerant as the core are introduced in this paper. This paper consolidates and extrapolates two prospective avenues for future development:
Its thermal performance is studied both numerically and exptl. The refrigerant flows and boils on the battery wall surfaces, which lowers the thermal contact resistance as well as enhances the heat transfer process. Therefore, the thermal performance of the battery module is improved.
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. Even under harsh environmental conditions, the 45 °C maximum temperature of the battery can be met by refrigerant cooling.
The batteries are the source of heat generation, while the refrigerant circulation system is the medium that removes heat from the battery. The refrigerant circulation system typically consists of a compressor, condenser, throttle device, and evaporator.
