Abstract

1,004,677. Centrifugal fans. LICENTIA PATENT-VERWALTUNGS G.m.b.H. May 4, 1962 [May 9, 1961], No. 17182/62. Heading F1C. [Also in Division H2] In an enclosed electric machine cooled by the closed circulation of a medium by an internal fan (not shown), a system of cooling tubes 7 are arranged within the path of the circulating medium, air for cooling the medium is passed through the tubes by an external mixed-flow fan 2, 13 having blades 13 with their free ends 14 inclined, and an end cover 15 of the machine is spaced from these ends and thereby forms an air guide. The external fan is of the reaction type and is mounted on the machine shaft 1. A diffuser portion immediately upstream of the cooling tubes 7 may be provided with baffles 16.
