FLUID DYNAMICS ANALYSIS OF A COMPUTER FAN FOR ENHANCED COOLING EFFICIENCY

Abstract

Modern computers generate significant heat during operation, necessitating effective cooling methods to prevent damage and ensure longevity. Among these methods, the computer fan is widely used, circulating air around heat-producing components. This study delves into the factors influencing the cooling efficiency of computer fans. By harnessing CFD analysis, this study identifies key factors affecting cooling performance, offering valuable knowledge in computer cooling technology. Results reveal an iterative process yielding a progressively uniform fluid velocity. The fan blade center exhibits the highest velocity (1089.32 cm/s), forming a distinct spiral airflow pattern. Higher fan density (1.15 g/cm3) results in increased airflow due to a strengthened thrust force. Air velocity peaks approximately 6 cm from the fan center, diminishing with distance. Insights from this study contribute to designing more efficient computer fans, crucial for optimizing cooling efficiency while considering factors like density, velocity distribution, and noise levels.
