Abstract
A waste heat recovery device includes a heat pipe in which a working fluid for transporting heat is enclosed, and a mode-switching valve for switching a heat recovery mode and a heat insulation mode. The heat pipe has a heating part for heating and evaporating the working fluid and a cooling part for cooling and condensing the evaporated working fluid. The heating part is made of a steel through which hydrogen gas permeates about at 500° C. and higher. In the heat recovery mode, the waste heat recovery device recovers heat of exhaust gas by using the heat pipe. Furthermore, in the heat insulation mode, a heat transport from the heating part to the cooling part is stopped.
