International ClassH01J 025/50Foreign Application Priority Data1991-05-03 KRAbstractDisclosed is a cooling apparatus for a magnetron, comprising a channel-shaped heat radiation plate for dissipating the heat generated from the anode of a magnetron, a yoke for supporting the heat radiation plate, an opening formed in both side walls of the heat radiation plate, and a secondary air passage formed in both side walls of the yoke for passing cooling-air to the opening, whereby the main stream of the cooling-air coming through the forward end of the heat radiation plate is pushed towards the anode in the rear region of the anode by the cooling-air driven through the secondary passage and opening into the rear region.Field of SearchFlow directing means in casingHaving control means for the temperature modifier Plural electrode temperature modifying Radiating type surface Having heat conducting path Distributed parameter resonator-type magnetron Anode with plural cavities Discharge device load with distributed parameter-type transmission line (e.g., wave-guide, coaxial cable) Steam dividing vanes, baffles, conduits, or the like for multiple cylinders Individual deflecting cylinder baffles Air duct with discharge ports or conduits With ventilating or cooling means FLUENT MATERIAL CONTAINMENT, SUPPORT OR TRANSFER MEANS With temperature control | |
