Abstract

Abstract: Aiming at the battery thermal management system (BTMS), this paper introduced three kinds of Ultra-thin Loop Heat Pipe (ULHP) with 1.5 mm thick wickless flat evaporator that can be applied for flake Li-ion power battery. We experimentally investigated the influences of the length of the entrance section, the shape of groove and the condenser position on the operation temperature, the thermal resistance, the start-up and heat leakage characters of ULHP, to further understand its operation principle. The results showed the ULHPs met the requirement of BTMS, the temperature with best structure was lower than 50°C. The effective operation relied on the smooth circulation. Optimizing the structure would reduce the temperature and thermal resistance, relieve the heat leakage and accelerate the start-up.
