Heat Transfer Augmentation of Heat Sinks Through Increasing Effective Temperature Difference

Experimental investigation of heat transfer and aerodynamic drag of novel heat sinks with lamellar fins

“…Studies of the thermo-aerodynamic characteristics and thermal resistance of heat sinks with stepped, trapezoidal plate and plate-fin stepped and trapezoidal fins were conducted in [8] using the CFD method. The results of research testify to the fact that stepped and cut fins allow for increasing the heat transfer coefficient by 1116% and decreasing the aerodynamic drag by 1545% at the reduced area of fins, but at the same time the thermal resistance of heat sinks is increased by 1525%.…”
