MANUFACTURING METHOD OF REACTOR AND HEATING DEVICE

PROBLEM TO BE SOLVED: To provide a technique to heat a thermosetting adhesive of core segments while suppressing the temperature rise of a coil.SOLUTION: A manufacturing method of a reactor disclosed by the present specification includes the following steps of: placing a first core segment and a second core segment of a reactor to face each other, with an uncured thermosetting adhesive sandwiched between the first core segment and the second core segment; facing one end of a heating core around which a heating coil is wound to the first core segment, and the other end of the heating core to the second core segment; applying an alternating current to the heating coil; generating alternating magnetic flux in a closed magnetic circuit extending through the first core segment, the thermosetting adhesive, the second core segment, and the heating core by the alternating current to the heating coil; and binding together the first core segment and the second core segment by a temperature rise and cure of the thermosetting adhesive, due to the heat in the first core segment and the second core segment caused by an alternating magnetic flux.SELECTED DRAWING: Figure 2 【課題】本明細書は、コイルの温度上昇を抑えつつ分割コアの熱硬化性接着剤を加熱する技術を提供する。【解決手段】本明細書が開示するリアクトル製造方法は、次の工程を含む。まず、リアクトルの第１分割コアと第２分割コアを、それらの間に硬化前の熱硬化性接着剤を挟んで対向させる。次に、加熱コイルが巻回された加熱コアの一端を第１分割コアに対向させ、他端を第２分割コアに対向させる。加熱コイルに交流を流す。加熱コイルの交流により、第１分割コアと熱硬化性接着剤と第２分割コアと加熱コアを通る閉磁路に交番磁束が発生する。交番磁束に起因する第１分割コアと第２分割コアの発熱により熱硬化性接着剤の温度が上昇して硬化し、第１分割コアと第２分割コアが接着される。【選択図】図２
