<P>PROBLEM TO BE SOLVED: To provide an induction heating device with cooling airflow improved and the cooling efficiency of a heated portion improved, as well. <P>SOLUTION: The induction heating device is provided with a control board for controlling the heating device, a heat sink for radiating a heat of a switching element on the control board, and a cooling fan for assisting radiation of the heat sink. In order to improve the cooling airflow raising a cooling efficiency, a circuit board is arranged in perpendicular orientation, under which the cooling fan is positioned to make flow the cooling airflow upward; and the cooling airflow is improved and an cooling efficiency of a heated portion can be improved, as well. <P>COPYRIGHT: (C)2009,JPO&INPIT |
