Title: ヒータ装置
IPC: H05B3/40
Filed: 2017-12-20
Abstract: 本開示のヒータ装置１は、長手方向を有する筒状のセラミック体２と、セラミック体２の内部に埋設された抵抗体３とを備え、セラミック体２の内側を長手方向に沿って流れる流体を加熱するものである。そして、セラミック体２の内壁に螺旋状の凸部２１が設けられている。これにより、セラミック体２の一方の開口より入る流体の一部がセラミック体２の内壁の螺旋状の凸部２１に沿って流れるため、加熱面に沿った流路の長さが見かけ上長くなり、流体が螺旋状の凸部２１の壁にあたることによって乱流になり易くなり、熱伝達性が向上する。【選択図】 図１
