<p><P>PROBLEM TO BE SOLVED: To provide a small inductor wherein a winding can be cooled efficiently. <P>SOLUTION: An inductor includes a cooling plate that is in contact with the outer peripheral surface of the winding and is an integral part of a core, and an energizing means that is sandwiched between the inner peripheral surface of the winding and the outer peripheral surface of the core and energizes the winding toward the cooling plate. Preferably, by having a part of the energizing means is sandwiched in between the core and the cooling plate, the energizing means is fixed to the core and the cooling plate. Preferably, the energizing means is a flat spring formed by bending a metal plate. More preferably, the metal plate includes its metal plate body and tongue portions formed by making U-shaped cutouts on the metal plate body, and the flat spring is formed by bending the tongue portions against the metal plate body. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
