Abstract

ThisResearch Report describes fan swirl effect on heat transfer of heat sink. The air flow was spread out by fan making a swirled airflow behind it. In this swirl flow, direction and velocity of the airflow has been changed. Fan swirl effect was used on cooling a crosscut heat sink. Here, the result of experiment with and without swirled airflow was compared. The experiment shows that swirled airflow enhances cooling rate of the heat sink by reducing its case-to-air thermal resistance, θca. Among the three variation of airflow rate given (2,8 m/s; 4,3 m/s; dan 6,6 m/s), the smallest one gives the highest cooling rate of the heat sink. Keywords : swirl fan, heat sink, crosscut, thermal resistance
