<P>PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device which can be efficiently assembled in short time. <P>SOLUTION: Both a first outlet 18 and a gas inlet member 23 have a horizontally long rectangle cross section with a length along a valve shaft 67 of a switching valve 32 longer than the length of the valve shaft 67 in a right angle direction. A welding part 42 which connects the first outlet 18 and the gas inlet member 23 is provided on a longitudinal axis 44 of a heat recovery unit 25, and the minimum radius surface 45 of the gas inlet member 23 is formed in curvature to extend near to the longitudinal axis 44 of the heat recovery unit 25. To form the curvature toward the vicinity of the longitudinal axis 44 of the heat recovery unit 25, the welding part 42 is provided obliquely to a detour 16. As the welding part 42 is slanted, a welding torch 65 can easily reach the welding part 42. As the welding torch 65 can easily reach the welding part 42, welding can be done easily, and operation time of the exhaust heat recovery device 10 can be reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
