Experimental study on heat transfer characteristics of a ⊥-shaped oscillating heat pipe used in the battery thermal management system

This paper introduces a ⊥-shaped oscillating heat pipe (OHP) with the purpose of improving the volumetric utilization of the battery thermal management system (BTMS) for electric vehicles. Distinguished from standard OHP structures, the evaporator and condenser sections of the ⊥-shaped OHP are orien...
