Abstract

PURPOSE:To prevent the flow which comes from the rear end from bumping into casing by bending the top part of impeller side plate in about circular arc shape and extending it to ahead of impeller main plate 5. Thereby to attain a high pressure. Also to simplify the constitution by using intake also as entrance of the impeller. CONSTITUTION:To bend the top part 17 of impeller side plate 15 in about a circular arc shape and to extend it to ahead of impeller main plate 5. Flow from the rear end 16 of vanes are affected by the impeller side plate 15 which are larger than vanes 8 or impeller main plate 5 and are bent in shape of about a circular arc or a straight line and does not hit casing 18. Therefore, the air flow is directed to guide vane 10 without having sudden deflection. Consequently energy loss is small and fan pressure can be largely increased. Also the total constitution can be siplified by the use of fan intake also as the entrance of the impeller.
