Abstract
Extending fins improve the rate of heat transfer or decrease convection. A fin is only for the reason of increasing the surface area in order to maximize heat transmission like a motor, heat exchanger, CPU, or to a heat-generating surface area. The benefit of performing thermal analysis on a flat fin is that it will tell how far heat is dissipated. This paper's primary purpose is to design and evaluate the thermal properties of rectanglular fin with varying geometry and content, and to expand the rectangular fin plate with Catia5R tools. Catia and Ansys are used to construct the geometries, and analyses of thermal properties are applied to them The tip is 5mm wide at present, decreased to 4mm. The aluminum alloy used in the manufacture of the rectangular fin body has thermal conductivity of 110-160 mK. The conducting coating on this paper is replaced with Aluminum Alloy 1100, which has a thermal conductivity of 210 to the mW/mk for the substrate and many unusual and prolonged margins. Case studies are used and graphed as well as total conclusions are drawn.
Highlights
Alessaet. al. [1] had studied the natural convection heat transfer enhancement from a horizontal rectangular fin embedded with equilateral triangular perforations
By observing the thermal analysis results, the overall heat flux is generated more in rectangular perforation fin
It is expected to be dissipating more heat from the surface and Temperature at the end of fin with rectangular perforation is minimum as compare to fin with other cases
Summary
[1] had studied the natural convection heat transfer enhancement from a horizontal rectangular fin embedded with equilateral triangular perforations. The heat dissipation rate from the perforated fin is compared to that of the equivalent solid one. The effect of geometrical dimensions of the perforated fin and thermal properties of the fin was studied in detail. They concluded that, for certain values of triangular dimensions, the perforated fin can result in heat transfer enhancement. The magnitude of enhancement is proportional to the fin thickness and its thermal conductivity. The perforation of fins enhances heat dissipation rates and at the same time decreases the expenditure of the fin material
