In this project our main aim is to analyses the thermal properties by using different types of materials for the fins with variable sizes slots to improve its performance and reduce its cost. The 3D modeling of engine with different slot sizes keeping fin size and number of fin same designed on Solid works and the analysis on the ANSYS steady state. Presently Material used for manufacturing cylinder fin body and we are comparing its performance using different material such as Aluminium, Beryllium, Magnesium. INTRODUCTION Heat exchangers are widely used in various, transportation, industrial, or Domestic applications such as thermal power plants, means of heating, transporting and air conditioning systems, electronic equipment and space vehicles. In all these applications improvement in the efficiency of the heat exchangers can lead to substantial cost, space and material savings. Hence considerable research work has been done in the past to seek effective ways to improve the efficiency of heat exchangers. The referred investigation includes the selection of fluid with high effective heat transfer surfaces made out of high conductivity materials, high thermal conductivity and selection of their flow arrangements. For both single and two phase heat transfer effective heat transfer enhancement techniques have been reported. However in the present work only SINGLE PHASE STEADY STATE NATURAL CONVECTION technique has been considered. The heat transfer enhancement methods reported in publications be summarized in many forms but primarily they may be grouped as active enhancement methods. The basis of any heat transfer enhancement technique lies in the utilization of some external power in order to permit the mixing of working fluids, the rotation of heat transfer surfaces, the vibration of heat transfer surfaces or of the working fluids also the generation of electrostatic fields.

Conclusion
We observed different types of fins, in
prototype (or) 3d model point of view in
all aspects, like structural and thermal
analysis of suitable alloys.
We observed with respect to proper
boundary conditions in all parameters.
The slots of the fins were increased
slightly for more heat transfer rate.
The project conclude that prototype of
Magnesium alloy is suitable among the
other in all aspects.
The results shows, by using fin with
material Beryllium and magnesium is
better since heat transfer rate of the fin is
more. By using modified fins the weight
of the fin body reduces compared to
existing rectangular engine cylinder fin.
Future Scope
Various other heat transfer methods
can be adapted in order to improve the heat
transfer rate and other fin configurations must
be added to see how they with stand to
temperatures.
Several other materials must be
deposited to know that the which material is
used for this purposeof heat transfer.
