Steady state forced convection heat transfer from vertical trapezoidal fin array and oblique trapezoidal fin array Simulation was done for both in which amount of heat transfer rate is calculated and compared. Test results indicate that vertical trapezoidal fin orientation array yield the lowest heat transfer rate. However the oblique trapezoidal fin array gave the best performance of heat transfer rate. The proposed work is concerned with the analysis of the improved heat transfer by forced convection on trapezoidal fin array and analysis of the structure of flows in a CFD. 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 vertical trapezoidal fin array information at different velocities in different heights is to examine the effect of a heat sink design .thermal resistance, pressure drop, and structure of the Nusselt number are compared with oblique trapezoidal fin array. Parameters such as the geometry of the heat sink, the height and the number of fins and the fin base height is regarded, in particular, the shape of the heat sink. The thermal model 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 with different parameters which are considered (height, speed) and all results will be compared with each other and the results have shown considerable increase in amount of heat transfer and Nusselt number in oblique trapezoidal fin array when compared to straight fin array for the same velocity of flow and both the properties have also been increased with increase in velocity.
