Method of Improving Fan Performance through Lengthening Blade in Miniature Backward-curved Centrifugal Fan |
| |
Abstract: | Extend the length of blade to the inlet area of a fan in the state of inclined cut shape can effectively improve the flow quality of fan flow passage and enhance the pressure of the fan. Taking the miniature backward-curved centrifugal fan as the object, this paper compares the numerical simulation results of original blade and other two length fans with extending blade and thus to get the conclusion that lengthen blade is one of the methods to improve the fan performance. |
