Abstract

A magnetron, comprising a cylindrical anode with a resonant space formed inside and a cathode therein, magnets installed on the top and bottom of the anode, a magnetic yoke arranged outside the anode and the magnet to form a closed cycle, and a cooling device, the The cooling device includes the main cooling device that constitutes the heat release path from the anode, and the auxiliary cooling device that constitutes the direct or indirect heat release path from the magnet, wherein the main cooling device is an anode heat conductor, one end of which is close to the outer surface of the anode The other end passes through the magnetic yoke and is exposed to the outside air. The auxiliary cooling device includes a magnet heat conductor close to the outer surface of the magnet. One side of the magnet heat conductor is in contact with the shell of the magnetron, or it is close to the magnetic The magnetic yoke heat conductor on the outer surface of the choke plate, one side of the magnetic yoke heat conductor is in contact with the shell of the magnetron.

Description

[0001] This application refers to Korean applications filed on April 18, 2002 with application numbers P2002-21231 and P2002-21232. technical field [0002] The present invention relates to a magnetron with improved self-cooling properties. Background technique [0003] Magnetrons are commonly used in microwave ovens, plasma light emitting devices, dryers, and other microwave systems. [0004] A magnetron is a vacuum tube that emits thermoelectrons from a cathode serving as a power source, and the thermoelectrons emit microwaves under the action of a strong electromagnetic field. Microwaves are sent through an antenna or feeder and act as a heat source for heating substances. [0005] Generally, a magnetron has an oscillating part and a magnetic circuit for generating microwaves, an input part for receiving and supplying power to the oscillating part, an output part for sending microwaves generated by the oscillating part and the magnetic circuit part, and a cooling magnet....
