WASTE HEAT UTILIZING DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

Disclosed is a waste heat utilizing device for an internal combustion engine (2), which comprises a cooling water circuit (4) having a radiator (12) for cooling the cooling water with the draft of ambient air, a Rankine cycle (6) having a first condenser (24) for condensing a cooling medium, and a refrigerating cycle (8) having a second condenser (36) for condensing the cooling medium.The first and second condensers (24 and 36) are water-cooled heat exchangers, and include a water circuit (44) having an air-cooled heat exchanger (46) for cooling the water having passed the first and second condensers (24 and 36), with the draft of the ambient air, and a heat-exchanging unit (53) composed of the air-cooled heat exchanger (46) and the radiator (12).
