<p>Disclosed is a cooling apparatus of magnetron, comprising a channel-shaped heat radiation plate 1 for dissipating the heat generated from the anode 10 of a magnetron, a yoke 6 for supporting the heat radiation plate 1, an opening 3 formed in both side walls of the heat radiation plate 1, and a secondary air passage 7 formed in both side walls of the yoke 6 for passing cooling-air to the opening 3, whereby the main stream of the cooling-air coming through the forward end of the heat radiation plate 1 is pushed towards the anode 10 in the rear region of the anode 10 by the cooling-air driven through the secondary passage and opening 3 into the rear region. <IMAGE></p> |
