An Experimental Analysis through a Stereo-PIV System of an Axial Fan Used in Electronic Equipment
Краткое описание
In the electronic industry, the large request of great device performances needs new and improved cooling system in order to dissipate significant thermal load. The research is often dedicated to study and analyse the characteristics of the existing cooling system such as the axial fans. A lot of numerical studies are performed to describe the convective flow generated by these common devices but in the scientific literature it is hard to find experimental analysis of their dynamic field. This deficiency of experimental data is probably connected with the three-dimensional flow which is produced by this equipment. In this paper the flow, generated by an axial fan, is studied and characterized through the use of a stereo-PIV system. So it is obtained a three-dimensional dynamic field and through the velocity maps the efficiency of the fan could be evaluated in order to its heat transfer capability. In the experimental analyses different rotation velocities of the axial fan are performed and the velocity maps are obtained at different distance from the outlet.
