Abstract

1302043 Transverse-flow fans BRAUN AG 12 Jan 1970 [14 Jan 1969] 1382/70 Heading F1C A transverse-flow fan comprises an impeller 2 arranged asymmetrically in a casing 1, the resultant minimum gap 3 between the impeller and the casing wall being arranged on the intake side, with the gap widening in the direction of the intake, and a common non-subdivided opening is provided for the intake and outlet. The portion 132 of the casing wall extending from the position of the minimum gap 3 to the outlet includes a semi-cylindrical part 10. The remaining portion 131 subtends an angle α of at least 30 degrees, say approximately 50 degrees. The casing may subtend an angle of less than 180 degrees, say about 130 degrees.
