Abstract

The operation of electronic devices results in generation of heat. Increase in operating temperature causes overheating problems and leads to failure of the component. The heat generated within the system must be dissipated to the surroundings. This is done by heat sink. In the present work electrical heater is placed in between two halves of heat sink with rectangular fins so that heat generated can be distributed equally. Heat transfer coefficient values are calculated from the measured data. Experiments have been conducted to determine the heat transfer coefficients under natural convection by placing fins in horizontal orientation in open air. From the experimental results it could be seen that, heat transfer coefficient h increases with heat input and also with temperature difference.
