<p><P>PROBLEM TO BE SOLVED: To solve the problems of an increase in cost by enlargement of a fan and an increase in noise due to an increase in air volume. <P>SOLUTION: An induction heating apparatus is provided with: a metal case 6, a switching element 3 which is one part of an invertor circuit to carry out induction heating by generating high frequency magnetic flux, a heat sink 4 for discharging heating of the switching element 3, and a discharge sheet 7 composed of high heat conductivity material such as graphite. In addition, one member of the discharging sheet is adhered and attached between the metal case 6 and the heat sink 4, and the heat discharging property is improved without enlarging the heat sink, increasing air volume in the fan serving as a cooling means, or separating a heating element from a substrate. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
