CFD Optimized Test Rig Design for High Precision Energy Efficiency Performance Measurements of Fans for Electronic Cooling

Abstract:

To measure the energy efficiency performance and the characteristics of electronic cooling fans a high-precision suction side test rig was designed according to the corresponding national DIN and international ISO standards. To evaluate the influence of the test rig design on the precision of the performance measurements of the fan, the complete test rig designs were analyzed in detail with the commercial CFD solver Star-CCM+ from Siemens PLM Software. Since at the test rig the pressure values of the fan are measured indirectly at the test rig chamber and not at the fan itself, the pressure values from the simulation as read out at the test rig chamber and at the fan itself were compared to deliver the required precision of the test rig design. Furthermore, the effect of the baffle plate and the throttle characteristics on the energy efficiency performance measurements of fans for electronic cooling have been analyzed.
