EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER BY NATURAL CONVECTION ON ALLUMINIUM CASTED V-SHAPED FIN ARRAY (original) (raw)

Heat generation in different industrial devices is very common problem. Fins are commonly used to dissipate heat by natural or forced convection. Fins are employed on industrial devices such as heat exchanger, reciprocating compressor and engine, electric motor, transformer and many electronic devices. The material, dimensions and geometry of the fin is the challenging factor in today's scenario, as optimum fin geometry can enhance heat transfer rate. It is observed that many manufacturers are using different fin geometry to increase the heat transfer rate such as rectangular, triangular fins with notches etc. Recently, the research has been carried out on v-shaped fin array. The comparative study between rectangular fin array and v-shaped fin array shows that V-shaped fin array has large improvement on heat transfer rate. The basic objective of this experiment is to generate the experimental data for the V-shaped fin array carrying a Natural convection. Hence to analyze the heat transfer rate from the aluminum casted v-shaped fin array without slots on notches and with slots on notes by providing angles to the basic fin plate.
