Abstract

PURPOSE: To imprve static pressure efficiency and the reduction of noise level of a diagonal flow fan by properly arranging the flow lines, twisted in span direction which are peculiar to a diagonal flow fan, in radial direction from the root side to the tip side of an outlet portion.
CONSTITUTION: The diagonal distance L1 between the radial-transfer-face-portion starting point Q (the boundary position between a radial-transfer-face-portion 5b and a slant portion 5a) of a rear side plate 5 and the root position H of the outlet portion 2b of an impeller A is set to satisfy 0≤L1<0.2D2 in comparison with the rotating diameter D2 at the tip portion width of the outlet portion 2b of the impeller A. The diagonal distance L2 between the radial-transfer-face-portion 4b starting point P (the boundary position between a radial-transfer-face-portion 4b and a slant face portion 4a) of a front side plate 4 and the tip position width of the outlet portion 2b of the impeller A is set to satisfy L1≤L2<(L1+0.2 D2) in comparison is rapidly corrected in radial direction as it removes from the outlet portion 2b of the impeller A, thus the static pressure efficiency and the reduction of noise level of the diagonal flow fan can be improved.
