Abstract
A cooling circuit for internal combustion engines includes an internal combustion engine, a pressure-feeding unit for feeding coolant, which cools the internal combustion engine under pressure, a valve unit having a plurality of heat exchangers connected in parallel thereto, an exhaust heat recovery system for recovering heat from exhaust air of the internal combustion engine by the coolant, a first circulation circuit including the pressure-feeding unit, the valve unit and the exhaust heat recovery system, and a second circulation circuit including the pressure-feeding unit and the exhaust heat recovery system.

13. A cooling circuit for internal combustion engines, comprising:
-
an internal combustion engine; a pressure-feeding unit for feeding coolant under pressure, the coolant cooling the internal combustion engine; a valve unit having a plurality of heat exchangers connected in parallel thereto; an exhaust heat recovery system for recovering heat from exhaust air of the internal combustion engine by the coolant; a first circulation circuit including the pressure-feeding unit, the valve unit and the exhaust heat recovery system; and a second circulation circuit including the pressure-feeding unit and the exhaust heat recovery system; a flow rate of the coolant flowing through the exhaust heat recovery system via the second circulation circuit being smaller than that of the coolant flowing through the exhaust heat recovery system via the first circulation circuit. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
