multistage cooling assembly, thermal management system and thermal management method for a motor engine

摘要

Thermal management systems and methods related to controlling temperature of internal combustion engines are provided. In one embodiment, a thermal management system includes an air intake structure defining an air intake passage therethrough coupled to a plurality of cylinders in an engine, a multi-stage cooling assembly, positioned in the air intake passage, including an air-to-coolant intercooler for cooling intake air and an air-to-air heat exchanger for cooling intake air, an air-to-coolant radiator fluidly coupled with the air-to-coolant intercooler of the multi-stage cooling assembly, a first fan operable to provide air flow to the multi-stage cooling assembly and the air-to-coolant radiator, and a second fan operable to provide air flow to the air-to-coolant radiator.
