[0035] When installing heat dissipation plate 4, heat dissipation plate 4 plays the key heat conduction and emission effect, and its material usually has good heat conduction performance, can quickly absorb and disperse the heat generated by magnetron, so as to guarantee that magnetron runs stably in the suitable temperature environment, when one side heat dissipation plate 4 is inserted, the clamping block 6 plays the function of positioning and fixing, and the clamping block 6 is extruded by heat dissipation plate 4, at this moment, the first spring 7 connected with it begins to contract, and the contraction characteristic of first spring 7 makes the clamping block 6 can smoothly slide into the inside of fixed block 5, and fixed block 5 provides stable track and support structure for the sliding of clamping block 6, ensures that the clamping block 6 does not deviate or shake during movement, guarantees the accuracy and reliability of the whole installation process, when the clamping block 6 slides to the upper side of the limiting block 8 fixed by heat dissipation plate 4, the first spring 7 stretches because of losing the external pressure of heat dissipation plate 4, and the extension force of first spring 7 pushes the clamping block 6 to embed in limiting block 8, and the existence of limiting block 8 defines the installation position standard of heat dissipation plate 4, and is fixed by the close embedding with clamping block 6, effectively prevents the deviation of the installation position of heat dissipation plate 4, so that heat dissipation plate 4 can be accurately installed at the predetermined position, and further guarantee the normal heat dissipation function and running stability of the whole heat dissipation assembly and magnetron.
