Abstract

The interrupted perforated fins are investigated by using numerical methods under natural convection. The numerical analysis is to be done for investigation of fin interruption effects. The continuous, inline interrupted, perforated inline interrupted, staggered interrupted & perforated staggered interrupted aluminium alloy heat sinks are designed & tested by changing various geometrical parameters. The numbers of perforations and the size of perforations are decided by calculating blanking ratio. Fin spacing (s) used in this analysis is 6.5 mm, 8 mm, 9 mm, 9.5 mm, 10.50 mm, 11 mm etc. And interruption lengths (G) 10 mm, 15 mm, 20 mm, 25 mm etc are considered. The effects of perforations, fin spacing & fin interruption length in inline & staggered interruptions are investigated numerically. In the present operating conditions & for perforated staggered interrupted fin arrangement, the thermal performances of the perforated staggered fins with blanking ratio 2.5 with 3 holes are finding to be better. Staggered arrangement & perforation will enhance the heat transfer rate. Staggered interrupted arrangement with perforation shows better performance as compare to inline interrupted with perforations.

Key Words
