Abstract: There is provided an exhaust heat recovery structure that may suppress boiling of coolant in a heat exchanger. The exhaust heat recovery structure includes a first pipe, a second pipe, a valve and a thermostat. Exhaust gas from an engine flows in the first pipe. The second pipe branches from the first pipe and a heat exchanger that exchanges heat between the coolant and exhaust gas is provided at the second pipe. The valve is provided at the first pipe or the second pipe. The valve adjusts a flow amount of exhaust gas flowing into the second pipe by opening and closing. The thermostat is equipped with a heat-sensing portion that is disposed inside the heat exchanger. When the temperature of the heat-sensing portion is high, the thermostat opens or closes the valve to reduce the flow amount of exhaust gas flowing into the second pipe.

Abstract: A heat recovery structure includes a pipe portion, a heat exchanging portion and an actuator. The pipe portion is inclined such that a side face of the pipe portion faces a diagonally lower side, and is configured such that exhaust gas from an engine circulates through the pipe portion. The heat exchanging portion is configured to communicate with the pipe portion and to perform heat-exchange between a heat medium and the exhaust gas flowing into the heat exchanging portion from the pipe portion such that the exhaust gas thus subjected to the heat-exchange with the heat medium flows out to the pipe portion. The actuator is configured to operate a selector valve configured to switch between a state where the exhaust gas circulates through the pipe portion and a state where the exhaust gas circulates through the heat exchanging portion.

Abstract: In a distribution flow path that allows engine coolant to circulate between an exhaust heat recovery unit and an engine, an upstream flow path on the upstream side of the engine and a downstream flow path on the downstream side of the engine are communicated with each other by means of a bypass flow path to thereby form a short flow path with a shorter flow path length than in a case where the engine coolant that has exited the exhaust heat recovery unit passes through the engine. A valve that can adjust the amount of the engine coolant flowing to the bypass flow path and a short flow path pump are disposed.
