Abstract:
An exhaust heat recovery device includes a first heat exchanger, a second heat exchanger, a gas passage, a liquid passage, and a self-pressure valve. The first heat exchanger performs heat exchange between exhaust gas and a heat medium so as to evaporate the heat medium. The second heat exchanger performs heat exchange between a heated target and the heat medium evaporated in the first heat exchanger, the heated target being defined as at least one of cooling water and oil so as to heat the heated target and to liquefy the heat medium. A loop heat pipe is formed by the first heat exchanger, the second heat exchanger, the gas passage, and the liquid passage.

Claim (Index 1):
An exhaust heat recovery device comprising:\n a first heat exchanger that evaporates a heat medium by performing heat exchange between the heat medium and exhaust gas discharged from an internal combustion engine; a second heat exchanger that heats a heated target and liquefies the heat medium by performing heat exchange between the heated target and the heat medium evaporated in the first heat exchanger, the heated target being defined as at least one of cooling water and oil; a gas passage that allows the heat medium evaporated in the first heat exchanger to flow toward the second heat exchanger; a liquid passage that allows the heat medium liquefied in the second heat exchanger to flow toward the first heat exchanger; and a self-pressure valve formed to be opened and closed, wherein an opening degree of the self-pressure valve is changed by pressure of the exhaust gas and a flow amount of the exhaust gas that flows into the first heat exchanger is adjusted in accordance with the opening degree, wherein a loop heat pipe is formed by the first heat exchanger, the second heat exchanger, the gas passage, and the liquid passage.
