Abstract: A magnetron cooling fin has a flat plate shape in which one or a plurality of corrugated regions are formed in a body of the magnetron cooling fin to improve cooling efficiency thereof. A magnetron cooling fin in which a corrugated region processed to increase a contact area in contact with air is formed around a through-hole through which an anode unit of a magnetron passes, thereby improving cooling efficiency thereof.
