Abstract

A microwave device of the magnetron type comprises an anode block with straps which are located with respect to one another along the axis of the block and are electrically connected to respective vanes of resonators of the block, these vanes having like polarity at the .pi.-mode of oscillations. The anode block is provided with cooling channels adapted to cool the vanes of the resonators and straps, said channels communicating with at least one chamber designed to distribute a liquid coolant and with at least one chamber designed to collect the liquid coolant, said chambers being rigidly connected with the anode block and provided with a hydraulic coupling between them. The straps of the anode block are implemented in the form of ring-like tubes. At least four vanes, connected with the corresponding ring-like tubes, are provided, each, with radially extending channels equal in number to the ring-like tubes which are connected with these vanes, the channels each communicating with a respective one of the ring-like tubes and serving together with the tubes as the cooling channels for respective vanes and straps. One of the radially extending channels, communicating with a respective ring-like tube, also has a communication with the coolant distribution chamber, while another radially extending channel communicates with the coolant collection chamber. The chambers are located along the axis of the anode block and each has a length, as measured in the direction of that axis, equal to at least a space between two outermost radially extending channels which communicate with respective chambers.
