Research on Thermal Management System of a Hybrid Electric Armored Vehicle
Advanced thermal management system (TMS) has the potential to increase the life of the cooling system components as well as decrease fuel consumption and carbon emissions. In the hybrid electric armored vehicle (HEAV), the combination of prime power and stored energy powers the vehicle driving system and advanced weapons subsystems. Because of the complicated energy transfer and the substantial heat rejection requirements, the thermal management in HEAV becomes a major design consideration. In the present paper, an integrated TMS employed in HEAV is described which uses controllable and high efficiency integrated electric fan (IEF) and accounts for all subsystems’ energy loss. As a result, the auxiliary load consumption imposed by the cooling system can be significantly reduced. And the first time, an oil cooling method of the brake resistor and a new correlation of heat transfer coefficient and wind velocity about flattube radiator are presented. According to the calculation, it has been observed that this TMS satisfies HEAV heat rejection requirement under stressing operational condition that low speed slope climbing.
