Abstract:

Cooling is important for appropriate operation of the power electronic devices. In low power applications, the cooling is done by air forced systems. Air forced cooling systems in low power valves are more reliable and simpler than water cooling systems. This paper examines air forced cooling model of the power electronic devices precisely with thermal transfer equations. This paper focuses on dimensions of heat sink and its channels in details and also, a flow chart for design of heat sink is presented based on air velocity and dimensions of channels. This paper calculates and simulates a case study. Finally, the results of simulations based on ANSYS, are compared with calculation results.
