There is a technique disclosed in Japanese Patent Application No. 0-234194. In this technology, a high-temperature end face of a thermoelectric conversion module (thermoelectric element) is closely attached to an exhaust pipe, and a low-temperature end face is closely attached to a cooling pipe, so that power is generated by a temperature difference between exhaust gas and cooling water. .

ともに、排気温度の高い位置に配置する必要がある。In a thermoelectric element, the power generation performance improves as the temperature difference between the high-temperature end face and the low-temperature end face of the element increases. For this purpose, a high heat transfer and high heat conductivity member is used as a heat conducting member (for example, a fin) for guiding the heat of the exhaust to the high temperature end face side of the element, and a large surface area is secured, and the heat dissipating member is disposed at a position where the exhaust temperature is high There is a need to.

触熱抵抗が増大し、十分な伝熱特性が得られない。[0004] A member having a high heat transfer coefficient and a high heat conductivity, for example, aluminum or the like cannot guide high-temperature exhaust gas because of insufficient heat resistance. In addition, heat resistance can be ensured by using ceramics, but it is difficult to form a pipe using only ceramics in terms of workability and strength. Conversely, SUS and the like with good strength and workability have a lower heat transfer coefficient and heat conductivity than aluminum and the like.
It is difficult to raise the temperature on the high-temperature end face side of the element, and the power generation efficiency decreases. When forming by combining both,
Since the thermal expansion coefficients are different, distortion occurs, the contact thermal resistance between the components increases, and sufficient heat transfer characteristics cannot be obtained.
