Development and Testing of a Heat Dissipation System Using Fins for a Motorcycle Exhaust Pipe

Abstract

The paper developed and investigate the use of fins as heat exchanger in dissipation of heat that arise from motorcycle exhaust pipe which can result in variety of degree of burns, affecting both users and passengers when in accidental contact with it. In this research work, copper pipe and aluminum fins were used because the heat transfer rate needs to be improved. The fabrication of the fins array was carried out with the use of 1mm aluminum material and 4mm copper pipe the base plate, the fins array are very potable and may be unfastened used on other exhaust pipes, since the fins are assembled with bolts and nuts. The analysis shows that the rate of heat transfer from the exhaust pipe (without fins) is1078W, while the heat transfer from the fins array was 2692.3W; which shows an increase in exhaust pipe heat transfer by factor of 2.5. Therefore, the risk of contacting serious burn when in accidental contact with the exhaust pipe has been reduced. It is hereby recommended that, the Semi rectangular fins profile can also be used for further research work because they are also effective, and the Copper fin may be considered for further work due to excellent thermal conductivity of the material.
