ABSTRACT:
Cooling device of a magnetron for a microwave oven, which includes a plurality of radiation fins disposed between an outer periphery of an anode cylinder and an inner surface of a yoke serving as a frame for radiating heat of a high temperature produced during osicillating operation of the magnetron for generating an electromagnetic wave. The temperature of the fins disposed centrally in substantially the same as the temperature of the fins disposed at both ends of the anode cylinder. This is accomplished by, the fins disposed centrally on the outer peripherey being arranged at a diffeent distance from the distance between the fins disposed on both ends of the anode cylinder or by the fins disposed centrally being made of different materials from the materials of the end.
