Title: Axial flow type propeller fan
Inventor: SUE HIDEYUKI
IPC: F04D29/38
Filed: 2002-07-24
Abstract: <P>PROBLEM TO BE SOLVED: To stabilize stream between blades of an axial flow type propeller fan used for a ventilator or an air-conditioning apparatus and reduce noise.  <P>SOLUTION: The axial flow type propeller fan has an impeller in which a plurality of blades 2 are joined to a blade attaching plate 1 integrally constructed with a boss 4 inserted in a motor spindle. In the propeller fan, a triangulated type projection 1a projected from a leading edge 2a of the blade 2 is integrally formed with the blade attaching plate 1. The projection 1a is slanted by a specific angle toward negative pressure surface 2c side of the blade 2. When the gas flows into the blade 2, the part of the gas which has flowed into positive pressure surface side 2b flows into negative pressure surface 2c side from the leading edge 2a of the blade 2, and boundary layer is evolved. Further, pressure variation is increased by interfering with the stream of the negative pressure surface 2c side simultaneously. However, if the projection 1a exists, vertical eddy 9 is generated at one side located at the inner diameter side, and the vertical eddy suppresses the development of the boundary layer at the negative pressure surface 2c side of the blade 2. Consequently, the state of the stream between blades is stabilized and the noise generated with the pressure variation is reduced.  <P>COPYRIGHT: (C)2004,JPO
