Abstract
An exhaust heat recovery device includes a multi-piece, chamber-shaped branching member with a draw-molded first chamber half having one inlet for introducing exhaust gas, and a draw-molded second chamber half having two outlets for discharging the exhaust gas. The draw-molded first and second chamber halves are integrally connected together to form a single chamber. A first flow channel extends from one of the two outlets of the branching member for circulating the exhaust gas. A heat exchanger is provided to the first flow channel for recovering potential heat of the exhaust gas. A second flow channel extends from the other one of the two outlets of the branching member for circulating the exhaust gas while bypassing the heat exchanger. A valve chamber houses a valve configured to open and close an outlet of the second flow channel.
