Abstract

PURPOSE: To improve the efficiency and suction of a fan, by using a centrifugal fan, the inner diameter of its front shroud being larger than the outer diameter of its rear shroud.
CONSTITUTION: The inner diameter of a front shrond 14 used for this centrifugal fan 4 is larger than the outer diameter of its rear shrond 15. Conically shaped driven vanes 13 draw the direction of discharge air except for the circumferential component near toward a driving shaft 12 to introduce it in a diffuser 3 designed for the axial wind, which can minimize the loss during the process.
