<p>PROBLEM TO BE SOLVED: To improve power generation efficiency by appropriately controlling the temperature of the hot junction of a thermoelectric conversion element in the case of using a thermoelectric conversion that converts exhaust heat into electric energy. SOLUTION: When the temperature of a heat generating member 133 rises and approaches the upper limit of heat resistant temperature of a thermoelectric conversion element 142, a bimetal deforming member 144 is deformed and the radius of curvature becomes small. As a result, a hot junction side heat connecting member 143 is made apart from the member 133 and the mechanical contact between the both is disconnected. For this reason, the heat of the member 133 is not conducted to the member 143 but the temperature rise of the element 142 is limited.</p> |
