Abstract

890,687. Cooling dynamo-electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 24, 1959 [July 29, 1958], No. 24425/58. Class 35. A dynamo-electric machine of the totally enclosed liquid-cooled type includes tubing 7 of corrosion resistant material, such as cupronickel, in contact with the steel yoke 3 of the machine. The tubing may be metallically bonded to the yoke by soft soldering, brazing or welding and is arranged in the form of an endless tube which undulates around the circumference of the machine with the major portions of the tubing parallel to the machine axis (Fig. 3). The coolant, e.g. water, is admitted at suitable points dependent on the pressure allowable in the tubing. The Provisional Specification refers also to an arrangement in which the tubing winds helically around the yoke of the machine. This subjectmatter does not appear in the Complete Specification.
