Abstract
A magnetron oscillator, a source circuit for energizing the magnetron oscillator and a fan are contained in independent casing units and the casing units are removably connected together into an integral assembly such that the fan circulates cooling air through the source unit and the magnetron oscillator unit.
Claims15
Magnetron apparatus comprising a magnetron oscillator unit for generating microwave power, a source unit containing a power source unit for operating said magnetron oscillator unit, a fan unit for circulating cooling air through said magnetron oscillator unit and said source unit, said magnetron unit, power source unit, and fan unit each being contained in a different metal casing, each casing having walls and at least two openings in its walls to provide an air passage through each casing, and means for connecting together the casings into an integral assembly, one air passage opening of a casing being coincident with one air passage opening of a different casing to which it is connected by said connecting means to form an air passage through said connected magnetron, power source, and fan casings having an air inlet opening provided by an opening in a wall of one casing and an air outlet opening provided by an opening in a wall of different casing.
