HEAT CONDUCTION MEMBER
PROBLEM TO BE SOLVED: To provide a heat conduction member which maintains a thermal coupling state and eases heat stress resulting from a difference in thermal expansion coefficients between ceramics and metal when a cylindrical ceramics body is covered by a metal pipe.SOLUTION: A heat conduction member 10 includes: a cylindrical ceramic body 11 having a passage which penetrates from one end surface to the other end surface and in which a first fluid that is a heating body circulates, the cylindrical ceramic body 11 where an outer peripheral wall is provided at an outer periphery; a metal pipe 12 which fits in an outer peripheral surface of the outer peripheral wall of the cylindrical ceramic body 11; and an intermediate material 13 which is located between the cylindrical ceramic body 11 and the metal pipe 12 and joined to the cylindrical ceramic body 11 and the metal pipe 12. In the metal pipe 12, the cylindrical ceramic bodies 11 are divided arranged in an axial direction and are provided sandwiching ring shaped soft materials 14, which are formed by one of a graphite sheet, an aluminum sheet, and a copper sheet.
【課題】筒状セラミックス体を金属管で被覆する場合において、熱的な結合状態を保ちつつ、セラミックスと金属の熱膨張係数の違いに起因する熱応力を緩和する熱伝導部材を提供する。【解決手段】熱伝導部材１０は、一方の端面から他方の端面まで貫通し、加熱体である第一の流体が流通する流路を有し、その外周に外周壁が設けられた筒状セラミックス体１１と、筒状セラミックス体１１の外周壁の外周面に嵌合する金属管１２と、筒状セラミックス体１１と金属管１２との間にこれらと接合した金属からなる中間材１３と、を備える。そして、金属管１２内で、軸方向に並んで複数の筒状セラミックス体１１が分断され、グラファイトシート、アルミシート、銅シートのいずれかであるリング状の軟質材１４を挟んだ状態で備えられている。【選択図】図５
