<p><P>PROBLEM TO BE SOLVED: To easily dissipate heat generated in a transformer to a heat sink through a bracket. <P>SOLUTION: The bracket 12 surrounding a transformer core 14 placed on the heat sink 13, a holding part 12a formed so that it can closely adhere to the transformer core 14, and heat transfer parts 12b extended to the heat sink 13 side from both ends of the holding part 12a. The lower end (fixing part 12c) of each heat transfer part 12b is fixed to the heat sink 13 by a bolt B1. A mounting hole 23 is formed at a location where the transformer core 14 is disposed in the heat sink 13, and a transformer core placing pedestal 25 is disposed in the mounting hole 23. The transformer core 14 is held between the transformer placing pedestal 25 biased toward the bracket 12 side by a compression coil spring 28 and the holding part 12a of the bracket 12, and is fixed to the heat sink 13. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
