Abstract

Objectives: The usage of Al6061 metal matrix composites as fins (extended surfaces), and the effect of heat treatment on the MMC's is pursued for the variations in fin efficiency. Methods/Statistical Analysis: Based on above requirement a metal matrix composite is prepared by the addition of silver treated copper particles in different weight percentages to the base metal Al 6061. Then the prepared MMC's are heat treated and solution zed. Test specimens (as-cast and heat treated) are statistically investigated using Taguchi and ANOVA (Analysis Of Variance). The performance of base metal, pre and post heat treated MMC's are compared on the basis of heat dissipation rate in pin fin apparatus for forced convection. Findings: Highest heat input of 65W, concentration of 15% and a distance of 2.7 cm is found to be effective for heat dissipation. Efficiency of heat treated Al 6061 Silver coated Copper MMC has augmented by 39% compared to base metal. Application: These MMC's has major application in heat sinks, Fins of condensers and evaporators etc.
