Title:
MAGNETRON AND APPARATUS THAT USES MICROWAVES
Document Type and Number:
WIPO Patent Application WO/2011/065030
Kind Code:
A1
Abstract:
Disclosed is a magnetron whereupon, when the radiator fins are viewed from the direction of the flow of the magnetron cooling medium, a region is formed wherein radiator fins are sparse and a region is formed wherein radiator fins are close together, improving the cooling efficiency of the magnetron. The magnetron comprises an anode tube body further comprising permanent magnets that are at least at both ends thereof, and a plurality of radiator fins that are disposed upon the periphery of the anode tube body and aligned with the central axis of the anode tube body. When viewed from the direction in which flows the coolant medium, which cools the anode tube body by way of the plurality of radiator fins, each of the plurality of radiator fins further comprises at least two fins whereupon notches are made upon parts of the radiator fins and the notched parts are bent differently from one another, such that a region is formed wherein the radiator fins are close together, a region is formed wherein the radiator fins are sparse, and at least two sets of fins are bent at angles such that the interval between radiator fins in the region wherein the radiator fins are close together is less than or equal to half that of the interval of the positioning of the radiator fins.
