Abstract: PURPOSE:To compactly form a device whole unit simplified in structure by mounting a heat absorbing vessel to a cylinder block of a horizontal engine and forming a cooling water heat exchanger and an exhaust heat exchanger in the heat absorbing vessel. CONSTITUTION:Cooling water, absorbing heat of an engine main unit coming out from a water jacket 1, is allowed to flow directly into a cooling water chamber 20 of a heat absorbing vessel 14 from an opening 2, radiating heat to pure water in a pure water chamber 26 through a heat transfer plate 15, and the cooling water, after it again radiates heat in a radiator 25, is circulated in the water jacket 1 of an engine E by a water pump 29. While exhaust of the engine E is allowed to flow into an exhaust heat radiator pipe 27 of the heat absorbing vessel 14 through an exhaust pipe 7, radiating heat to pure water, and the exhaust is emitted to the atmosphere from a muffler 10. On the contrary, pure water, allowed to flow into the heat absorbing vessel 14 by a circulating pump 31 from a pure water supply source 30, absorbs cooling water waste heat and exhaust heat, thereafter the pure water passes through an exhaust heat recovery circuit 12 recirculating to the supply source 30. Accordingly, forming cooling water and exhaust heat exchangers 4, 8 together in the heat absorbing vessel 14, a device whole unit enables compactness to be attained.
