Designing a Heat Sink for CPU Cooling with ANSYS AIM - Application Brief

Simulations were performed that varied the number of fi ns, fi n height and surrounding fluid for a heat sink. After considering both the heat dissipation and the cost of materials, students determined that the optimal design is 14 by 14 fins with a heat fi n height of 20 mm. Of the three fluids studied, water and mineral oil both outperformed air.
