<P>PROBLEM TO BE SOLVED: To promote warming-up of an engine of a hybrid vehicle, and to improve the utilization efficiency of energy in the hybrid vehicle. <P>SOLUTION: A heat management system 1 comprises an engine 2, an H/V motor 3, a first passage 4 in which a first coolant circulating in the engine 2 circulates, a second passage 5 in which a second coolant carrying out heat exchange with the H/V 3 circulates, a first heat exchanger 7 carrying out heat exchange between the first coolant and the second coolant, a first bypass passage 10 with which the first coolant bypasses the first heat exchanger 7, a second heat exchanger 8 carrying out heat exchange between the first coolant and the exhaust of the engine 2 and between the second coolant and the exhaust of the engine 2, a second bypass passage 12 with which the first coolant bypasses the second heat exchanger, a recovery machine 17 recovering waste heat through the second coolant after passing through the second heat exchanger 8, and a third bypass passage 22 with which the second coolant bypasses the second heat exchanger 8 and the recovery machine 17. <P>COPYRIGHT: (C)2009,JPO&INPIT |
