<P>PROBLEM TO BE SOLVED: To miniaturize a waste heat recovery system that heats cooling water by using the heat of exhaust gas. <P>SOLUTION: The waste heat recovery system is composed of: a heat recovery unit 14 which heats cooling water; a heat recovery path 12 which sends exhaust gas to the heat recovery unit 14; a detour 13 which makes the heat recovery path make a detour; a valve 24 which closes the detour 13 or the heat recovery path 12; and an actuator 18 connected to a turning shaft 22 which turns the valve 24. The heat recovery unit 14 is arranged so as to contact with the detour 13, and a heat transfer prevention part 35 for preventing the transfer of heat to the heat recovery unit 14 from the detour 13 is arranged in a region which is the inside of the detour 13, and corresponds to a region in which the heat recovery unit 14 is arranged. The heat transfer prevention part 35 for preventing the transfer of the heat to the heat recovery unit 14 is arranged in the detour 13. Since the heat transfer prevention part 35 is arranged in the detour 13, the heat recovery unit 14 can be arranged so as to contact with the detour 13. By arranging the heat recovery unit 14 so as to contact with the detour 13, the waste heat recovery system 10 can be miniaturized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
