Claims

[Claims for Utility Model Registration] 1. Heat dissipation fins provided radially on the outer periphery of the collector of the output tube, a cover surrounding the outer periphery of the heat dissipation fins, an opening provided on the side surface of the cover, and A radiator for an air-cooled output tube, characterized in that it is provided with a blower duct that covers the surrounding area and blows cooling air. 2. The radiator for an air-cooled output tube according to claim 1, wherein the radiating fins are arranged vertically at approximately the center of the axial length of the cover and perpendicular to the axis of the collector.
1. A radiator for an air-cooled output tube, characterized in that the radiator has a partition plate for separating the parts, and the opening is provided at the position of the partition plate. 3. Heat radiation fins provided radially around the collector outer periphery of the output tube, a cover surrounding the outer periphery of the heat radiation fins, a blower duct provided at the lower part of the cover to blow cooling air from the air outlet, and the cover. In an air-cooled output pipe radiator having an air exhaust duct provided at the upper part and discharging the cooling air from the air exhaust port, the air duct and the air exhaust duct go inside from the air outlet and the air exhaust port. A radiator for an air-cooled output tube, characterized in that the radiator has a horn shape whose cross-sectional area gradually decreases according to the following, and is provided along the cover.
