ENGINE INTAKE AIR COOLING DEVICE AND COOLING METHOD

摘要

An intake air cooling device wherein a first cooling water circuit causes cooling water coming out of an engine (10) to flow through a first intake air cooling device (71) and return to the engine (10) again and a second cooling water circuit causes cooling water coming out of the engine to flow through a second intake air cooling device (72) and return to the engine (10) again. The intake air cooling device comprising a heat exchanger (76) that exchanges heat between the cooling water that has come out of the engine and is heading towards the first intake air cooling device (71) and the cooling water that has come out of the second intake air cooling device (72) and is heading towards the engine.
