Abstract: A magnetron device composed by improving the medium or large size magnetron device having an output power of the order of 500 watts in ultrahigh frequency, which comprises as cooling means an assembly of a natural air-cooled type radiator formed of aluminum or alloy thereof and which, accordingly, does not necessitate the cooling means like blowers provided to conventional devices. Said device has such advantages that noise is eliminated during operation and that it is light and compact and therefore it is particularly suitable for a domestic-use microwave range.

Abstract: 1,225,855. Magnetrons. MATSUSHITA ELECTRONICS CORP. 26 Aug., 1968 [7 Sept., 1967], No. 40721/68. Heading HID In a magnetron assembly which dispenses with forced cooling, Figs. 1 and 2, the anode block 2 of the magnetron 1 is mounted through an aluminium slab 3 having arrays of aluminium cooling fins 8 clamped to each end, the upper surface of the block supporting the solenoid or permanent magnet 5 and yoke 6. The fin arrays rise above the top of the magnetic system, to protect the latter; the anode block may be secured within block 3 by soldering or by the use of a thermally conductive resin. Dimension and weight data are included.
