Abstract
In this paper are presented the results of an experimental study on the chimney effect on natural convection induced airflow for cooling electronic equipment. In order to enhance the natural convective air-cooling capability, the chimney effect is increased by placing the casing wall inclined. Experiments have been carried out using a ventilated thin electronic equipment-casing model with a plate heater and PCB heater inside and inlet and outlet vents on the walls of the casing. In our study, the angle of inclination, the amount of heat of dissipation was varied with casing which has no front and back wall.
