Modelling and thermal analysis of air-cooling system with fin pitch in IC engines

ABSTRACT

Excessive heat from the system in IC engines is removed by using the air-cooling system in order to avoid damaging and overheating of IC engines. Fins are most preferably used now to enhance convective heat transfer without the use of an excessive amount of the primary surface area. Choosing the configuration of the fin is very important in order to attain maximum effectiveness of the fin. The heat transfer from surfaces in general is enhanced by increasing the heat transfer area of the surface or the heat transfer coefficient between the surface and its surrounding. Extended fins are well known for enhancing the heat transfer in IC engines. Therefore, it is important for an air-cooled engine to utilise the fins more effectively to obtain uniform temperature distribution in the cylinder periphery. The aim of this paper is to investigate the thermal behaviour of the cooling system with fin pitch and surface geometry in ANSYS and modelling is done using solid works software, in order to compare its performance over the conventional fin design.
