The heat generated by the internal electro-mechanical device is not transferred to the outside, to degrade the performance of the electronic device, or the cause of failure. Heat sinks are used to control the heat. Thermal performance of the heat sink of the pine type and pin type was analyzed using ANSYS software. The numerical results were compared with the thermal performance of the pine type and pin-type heat sink. The results of the numerical simulation showed that Pine type heat sink showed an approximately 58 percent better heat transfer rate with forced convection than Pin type heat sink.
