Abstract
A device for recovering heat from a hot gas stream comprises a gas diverter valve and a gas/liquid heat exchanger. The diverter valve comprises a valve body; a valve element movable between a bypass position and a heat exchange position; and a gas inlet and a gas outlet formed in the valve body. The heat exchanger comprises a heat exchanger core comprised of a stack of core plates arranged parallel to the exhaust gas flow path, and the heat exchanger is located outside the exhaust gas flow path and may be spaced therefrom so as to avoid unwanted heat transfer with the valve in bypass mode. The heat exchanger may include a bottom-most gas flow path adjacent to the bottom plate, and may include a mounting plate which is mechanically secured to the valve body, with a thermally insulating gasket provided between the mounting plate and the valve body.
