Summary:To provide a fluid electrical heating device capable of achieving increased heating efficiency in heating by electrical heating of a fluid, both reduced size and increased capacity in a heating device, and a safety operation.SOLUTION: The present invention relates to a fluid electrical heating device in which a part of secondary winding 30, of an annular transformer 24, with a number of turns of 1 in a winding direction is formed of a heating part 10 where a plurality of heating tubes 12 in which a fluid to be heated flows are assembled in parallel. Fluid supply and discharge means 40 to supply and discharge the fluid to be heated is connected to both ends of each of the heating tubes 12 constituting the heating part 10. The heating part 10 is arranged in a peripheral position excluding a core opening 26 of the annular transformer 24. Each of the heating tubes 12 constituting the heating part 10 is electrically connected, one side by one side, at both ends by a tube end short circuit electrode 32. Remains of the secondary winding 30 in a winding direction are formed of a secondary closed circuit formation conductor 34 that extends from one of the two tube end short circuit electrodes 32 to the other thereof.SELECTED DRAWING: Figure 1 【課題】流体の電気加熱による加熱効率の高効率化、加熱装置の小型化と大容量化との両立、及び安全運転を可能にする、流体の電気加熱装置を提供する。【解決手段】本発明は、環状トランス２４の巻数が１の二次巻線３０の巻き方向の一部が、内部に被加熱流体が流れる加熱管１２の複数本が並行して集合した加熱部１０で形成される、流体の電気加熱装置であって、加熱部１０をなす加熱管１２の各々の両端部には、被加熱流体を供給し且つ排出させる流体給排手段４０が接続され、加熱部１０は、環状トランス２４の鉄心間口２６を除く周辺位置に配置され、加熱部１０をなす加熱管１２の各々は、両端部で片側ずつ管端部短絡電極３２により電気的に接続され、二次巻線３０の巻き方向の残部は、２つの管端部短絡電極３２の一方から他方まで延びる二次閉回路形成導体３４により形成される。【選択図】図１
