Abstract
Abstract 551,895. Cooling R÷ntgen-ray tubes. GRAVES, E. B. Sept. 11, 1941, No. 11651. [Class 98 (i)] [Also in Group XL] In a liquid-containing cooling jacket for an X-ray tube means are provided for causing circulation of the liquid to conduct the heat to the wall of the jacket, and also means for causing a flow of cooling fluid against the external surface of the jacket. As shown, the tube is mounted in a shell 5 filled with oil or other insulating and cooling liquid, which is circulated by an impeller 14 operated by a motor mounted on a cap closing the end of the shell. A tubular member 18, which may be of lead or bakelite, serves to guide the liquid flowing towards the impeller into contact with the tube, and that returning from the impeller into contact with the wall of the shell; it serves also as a screen for the rays. The shell 5 is surrounded by a metal jacket 20, between which and the shell air is caused to flow by a fan or blower 23 in a casing 24 mounted on the jacket.
