Abstract
1498111 Transverse flow blowers INTERNATIONAL STANDARD ELECTRIC CORP 20 March 1975 [26 March 1974] 11627/75 Heading F1C A transverse-flow blower comprises a baffle plate 2, Fig.5a, having a spiral portion merging on the delivery side 4 with a plane position; a vortexforming system between the delivery side and the inlet side 8 and comprising at least two guide walls such as 5, 6 which jointly converge towards the rotor 1; a step 22 (or an edge 23, Fig.4b, or an undulation) located at 0 to 0À5 times the rotor diameter from the outlet edge 26 and serving to deflect the air current towards the vortex former and thereby stabilize the flow and reduce noise; the baffle plate having a variation, along the length of the rotor, of the shape of its inlet edge 3 or of the size of the gap between itself and the rotor, or both; and those edges of the guide walls which are near the rotor defining one or more slots parallel to the rotor axis, inclined with respect to the rotor axis (17), Fig.5b, tapered (17) Fig.5c, or stepped (20, 21 Figs.5d or 5e). The inlet edge 3 may be curved, as shown, or stepped, Fig.3a (not shown). As shown in Fig.4b, recirculation of air to the delivery side of the blower occurs between the guide walls 5, 6. Instead of being connected to the guide wall 6, the adjacent casing wall may be connected to the guide wall 7 to provide additional recirculation or to the guide wall 5 to eliminate the recirculation.
