Abstract

PURPOSE: To increase wind volume without enlarging the outside diameter of guide vanes by making smaller the edge of a guide vane of a turbofan than the diameter of outlet nozzle.
CONSTITUTION: The edges of the inner diameter of guide vanes 4 and 6 are provided with projected portions 11 which are smaller than outlet nozzles 7 and bell mouths 9. The air introduced from a suction nozzle 1 increases static pressure by blades 3 and 5, forming turbulent air flow. The turbulent air flow enters the inside of the guide vanes 4 and 6 from outside, being arranged in a laminar flow. With this construction, the wind volume can be increased without an enlarged outside diameter of guide vanes.
