<p><P>PROBLEM TO BE SOLVED: To enhance a cooling efficiency of a transformer for high-frequency induction heating by omnidirectionally absorbing a generated heat of a core with a primary winding wound, downsizing the transformer. <P>SOLUTION: The transformer 1 for the high-frequency induction heating is manufacturered by winding the multi-winding conductor (the primary winding 4) around a hollow core 2, encapsulating the primary winding 4 annularly formed by the winding of the multi-winding conductor (the primary winding 4) at the both end sides of the core 2 in a secondary winding 6 with a single-winding conductor formed in an annular hollow shape, providing inflow ports for a cooling water (a tube 3 for the cooling water, a hole 65a for the cooling water) to a secondary winding 6 in order to flow the cooling water for immersing the primary winding 4 and the core 2 into the secondary winding 6, and providing an outflow port for the cooling water in the secondary winding 6 (a tube 5 for the cooling water, a port 67a for the cooling water) to the secondary winding 6 so as to face to the inflow port for the cooling water (the tube 3 for the cooling water, the hole 65a for the cooling water). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
