<p>PURPOSE:To precisely discriminate a no-load state and a light-load state and prevent no-load damage to a magnetron equipment by fitting a temperature detecting element near an anode having the largest temperature rise. CONSTITUTION:A thermistor 17 is provided in contact with or near an anode 9, it is inserted between a cooling fan 13 from the side where the cooling air flows out, and it is fitted by the coupling of a coupling hole provided on the cooling fan i3 end a projection provided on the thermistor 17. The thermistor 17 is kept in contact with the downstream section of the anode 9 not blown with the wind W from a cooling fin 6 directly, and the temperature of a magnetron 4, i.e., the temperature of the anode 9, can be precisely detected.</p> |
