데스크 탑 컴퓨터내에 팬의 형상별 유동 성능 해석에 관한 연구 A Study on Flow Performance Analysis by the Shape of Fan in Desktop Computer
pp.621-626
In this study, by analyzing the flow rate and the pressure applied to the fan for the flow of air with room temperature into the fan in desktop computer, it was investigated which model was suitable for flow resistance. When comparing the speed distribution of air flow by model according to fan shape, model A was able to confirm that the fan performance was not good but the external flow was widely distributed. And model B was able to know that the performance was good but the external flow was smaller. Model C was found to have good performance and a wide distribution of outer flow. In cases of three models, it was equally shown that the pressure was highest on the blade side of the inlet where the air enters. Model B receives more pressure than models A and C when the same air flow rate is applied, so models A and C are considered more efficient cooling fans than model B. When considering the flow rates and the pressures acting on the model, model C is thought to have relatively good performance. By utilizing this study result, the flow rate and pressure are investigated without flow experiment by the shape of fan in desktop computer, and the flow capacity can be seen.
