ABSTRACT:
A magnetron having an anode cylinder, cooling fins fixed thereto, permanent magnets vertically superposed on the anode cylinder and a yoke, serving as a magnetic path, for surrounding these components. The cooling fins extend on the windward direction to facilitate a discharge of the air in the orthogonal direction to the air blowing direction by an arrangement such that an outer width of the fins and a width of the yoke or the former is equalized to a diameter of the anode cylinder. Also included are a dielectric heater having a heating space for accommodating materials for heating and a space for accommodating the magnetron, an inverter power supply and a cooling air blower. The cooling air is discharged to the heating space and/or to the outside via a vent hole formed in a partition wall after impinging on the anode cylinder while cooling the fins.
