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.

Abstract: An exhaust heat recovery device comprises: a heat exchanger for recovering heat from exhaust gas; a second flow channel for circulating the exhaust gas during exhaust heat non-recovery; a branching member for connecting an inlet of the heat exchanger and an inlet of the second flow channel; a merging member for connecting an outlet of the heat exchanger and an outlet of the second flow channel; a valve for blocking the outlet of the second flow channel; and a valve chamber for housing the valve. The branching member is comprised of a single chamber formed by joining together a first chamber half in which one inlet is provided, the first chamber half being draw-molded from a blank, and a second chamber half in which two outlets are provided, the second chamber half being draw-molded from a blank.

Abstract: A lightweight exhaust component cover having a small number of components is disclosed. In the exhaust component cover, an internal plate is formed by bending part of a single plate at both ends, and the internal plate is joined to the inside surface of an external plate.
