In reciprocating engines, transfer of heat is the primary task for increasing the engine efficiency and effectiveness rather than liquid cooling; the air cooling is most preferable for its simplicity. By increasing the contact surface and usage of high value heat transfer coefficient metals air cooling is highly possible compared to other metals aluminium fin heat exchanger provides better corrosion resistance due to a better galvanic balance of the materials and more cost effective . In this experiment, we have take Aluminium 6063-T6 rod with different surface roughness to analyze heat transfer for better rate of heat transfer. Usually smooth surfaced aluminium 6063 alloy is used as heat exchangers here same aluminium 6063 alloy with rough surface fin has been tested. The high contact between air and the metal surface this is one of the heat transfer enhancement method used traditionally and not in practical applications. In this paper comparison has been done on for the Aluminium 6063 rod with three different surface roughness values. Fins are surface that extend from an object to increase the rate of heat transfer to or from environment by increasing convection. In engine for better heat transfer even in mode of convection, heat is exchanged efficiently
