The Control Method with Energy Saving of the Inflow Turbulence for Router Cooling Fan

Article Preview

Abstract:

In this paper, the characteristics of the inflow turbulence intensity of a router cooling fan are studied experimentally. Screens with different parameters are designed to control the inflow turbulence intensity. The flow field is measured by hot-wire anemometer. The results show that the inflow turbulence intensity is closely connected with the parameters of the control screens. The inflow turbulence intensity can be significantly reduced when the screen with small meshes is used, while the mean flow is barely affected by the screen.
