Several automobile industries are working on it to maintain a proper temperature for increasing the efficiency and also to prevent the engine from thermal damage. So it become important to analyse fins structure for better heat transfer rate. High temperature on the surface of engine block effect the efficiency of engine. Increasing number of fins is not only the criteria to increase the heat dissipation from the surface of fins. Generally, rectangular fins are used in motor bike engine, although the temperature at the surface is in safe limit. By introducing new geometry of fin & if the minimum temperature of new geometry is less than or near about the minimum temperature of rectangular fin is not only help in increasing the efficiency of engine block but also it may help in reducing the weight of engine block. Convective heat transfer is the mechanism of heat transfer and it depends on convective heat transfer coefficient and Contact surface area with air. Fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. And the analysis is done by numerical method and on Solid Works software.
