Studies on PCU cooling system’s design of fuel cell vehicle

Abstract:

Power control module is an important component of fuel cell vehicle. Power control unit (PCU for short), due to its own operating principle and function structure, has generating heat components with great power. The cooling system of the power control module designed in this paper provides two options, and checks and calculates them. In the cooling system power control module, the key components are used the forced heat transfer measures, and utilize fluent software to do numerical simulation of cooling structure, according to the results of this simulation, the cooling structure is optimized, the power control module actual operation is good.
