A Study of The Application of Vortex Tube for Temperature Reduction of Heated Volume
Abstract
Vortex tube is the device that used for spot cooling. It uses only compressed air as the main supply to induce the swirl phenomena inside the tube. It consists of the cold and hot end at the opposite side of the tube. The cold outlet releases cold air that can be used for cooling application while the hot air is dumped out as a waste. In this research, the vortex tube is designed and applied to cool down the simulated heated volume with an electronic heater. The hot end of the vortex tube is modified with four different numbers of outlets, 4 holes, 8 holes, 12 holes and 16 holes in order to achieve the best cooling efficiency. The results show that the increasing number of hot outlet holes can decrease the cold end temperature. The heat transfer rate inside the vortex tube is improved by letting the high amount of heat escaped through the hot end with a mass flow rate whereas the vortex phenomena inside is still maintained. In the experiment, the cooling of the heated volume using vortex tube can reduce the air temperature inside the volume from 50 OC to the lowest at 38 OC during 60 minutes of operation which can prevent the electronic failure due to the accumulated heat inside the box.
