摘要
The purpose of this research is to study the performance of axial fan of the porous thin plate. First, the area of the holes of the porous thin plate is changed to estimate the influence of the porous thin plate on the performance of the fan. This study is conducted by simulations and experiments to find out the factors that will impact the performance of the fan. The results show that if the area rate of the porous thin plate and the fan is smaller, the difference of the simulations and experiments will become greater. When the area rate is more than 80%, the difference of the simulations and experiments will turn to be 10% lower. The results of experiments show that the fan size and fan thickness are the two main factors that produce the influence on the porous thin plate. If the thickness of the bar of the porous thin plate is 2.0 mm, the performance of the fan loss would be the smallest. As to the assembly position of the porous thin plate, unilateral assembly makes the performance of the fan better than bilateral assembly. This is in relation to the area size of the porous thin plate. Fan tray is bilateral assembled. The performance of the fan tray can be improved in the following two ways. To use the thicker fan as the static pressure is greater, or to use the fan with lower air flow as the loss will be less.
