Analysis of Varying Geometri Structures of Fins using Radiators

Radiators are heat exchangers used to transfer thermal energy from one medium to another medium. In the existing plain fins type radiator are commonly used, which are usually set up in a cross flow arrangement made up of aluminum and copper alloy. Powerful fan and water pump is accompanied in this to greatly improve heat dissipation rate. For higher cooling capacity of radiator, addition of fins is one of the approaches to increase the cooling rate of the radiator. This method follows the principle of increasing contact surface. Contact surface can also be increased by varying fin geometrical structure. In this project simple modification has been carried out in the existing fin geometry with a view to improve its heat dissipated rate. The varying fin structures are Box type, Sharp type, Round type. Sharp type radiator fins is fabricated to evaluate the effectiveness of the radiator. Also comparison of conventional coolant with SiC Nano fluid has been carried out by using Solid works and Ansys software. The result are compared with both analytical and experimental fin design is concluded.
