Abstract :
In order to dissipate excessive heat generated within electrical circuit boards heat sinks are conventionally being used. Heat sink facilitates high performance, safe, long life and makes reliable electronic devices. Heat sinks are generally available in different shapes and sizes. In this paper rectangular shaped heat sink, where natural and forced convection is examined at different orientation of sink, i.e. horizontal and vertical has been taken. The complete analysis has been carried out by using software, where the CAD model of heat sink has been modeled in Solid works and the CAD model is imported to finite element tool i.e. ANSYS fluent where the governing equations are solved for given boundary condition. During analysis the overall heat transfer has been examined and the results have been compared with other published work. Form the result it has been observed that the heat transfer within heat sink at different orientation is quite different.
