要約

An effective thermal management system that can maintain the maximum temperature and temperature difference in a desired range is essential to ensure the performance and safety of lithium-ion batteries. In this paper, a minichannel cooling system for high-power prismatic battery thermal management is investigated numerically. The system thermal performances when using different fluids and their corresponding nanofluids as coolants are compared initiatively. It is seen that water achieves a better cooing effect than ethylene glycol and engine oil. However, the impact of adding nanoparticles is more remarkable for fluids with lower thermal conductivity (i.e. ethylene glycol and engine oil) especially for engine oil. The nanoparticle addition is able to greatly reduce the cell maximum temperature but has a limited effect on the temperature uniformity. Apart from that, different influencing factors including the flow velocity and coolant inlet temperature on the minichannel cooling performance and the enhancement of adding nanoparticles are studied. It is observed that all of these factors have significant impacts on the minichannel cooling effects.
