The proposed work is concerned with the analysis of the improved heat transfer by forced convection on the pin fin with trapezoidal fin and analysis of the structure of flows in a CFD. This working research thermal performance of the circular pin fin. The value of heat transfer coefficient obtained for the surface of Nusselt number of the pressure drop of the study, the heat resistance and the pressure drop of the heat to the circular pin fin heat dissipating fins trapezoidal fin information at different velocityes in different heights is to examine the effect of a pin fin design .thermal resistance, pressure drop , and structure of the Nusselt number are compared with experimental results and the simulation results .Parameters such as the geometry of the fin plate and the pin height and number of the fin of the fins of the fin base height is regarded , in particular, the shape of the heat sink. the thermal model of the computer system with various fin heat sink design of the geometry has been selected and the characteristics of the heat sink thermal fluid flow stream were studied. The pin fin plate and trapezoidal heat sinks of the fin geometry were used with base plate to improve heat dissipation. Some features formed in an infinite variety of geometries resulting in different heat transfer characteristics. The objective of the present work is to find the heat transfer rate and distribution of the airflow on surfaces installed pin fins with different parameters (height, speed) and all results will be compared with each other.
