Abstract:
An exhaust heat recovery device includes an evaporator for evaporating working medium sealed thereinto by exhaust heat from an internal combustion engine, a condenser for cooling the working medium evaporated at the evaporator, and a communication portion for communicating the evaporator with the condenser in an annular shape. The exhaust heat recovery device further includes an internal pressure operating valve adapted to be closed when a pressure of the working medium is equal to or more than a predetermined pressure, and a temperature operating valve adapted to be closed when a temperature of the coolant is equal to or more than a predetermined temperature. The internal pressure operating valve and the temperature operating valve are disposed between a downstream side of the condenser and an upstream side of the evaporator.
