ABSTRACT:
A high frequency heating arrangement includes a power converting unit with one or more semiconductor devices which dissipates a slight heat loss. A magnetron receives an output from the power converting unit and supplies electromagnetic waves to a heating chamber. The magnetron dissipates a heat loss that is relatively larger than that of the power converting unit. A cooling fan has a motor which dissipates a heat loss which is relatively smaller than that of the power converting unit. The cooling fan is for cooling the power converting unit and the magnetron. A case is provided in which at least the power converting unit and the magnetron are housed and which is made of an electricity-conductive material. A cooling air passage, along which the motor and the case are arranged, and through which air flows from said cooling fan is provided. Air sent from the cooling fan first cools the motor, then cools at least a portion of the power converting unit, and finally cools the magnetron.
