Abstract Title : Electrically Actuated Micro-Channel Heat-Transfer Device
|
Abstract :
Research is being conducted on an experimental device whose purpose is to dissipate heat from a smaller area, to a larger one. This device is an “Electrically Actuated Micro-Channel Heat-Transfer Device”. In the experiment, two glass plates coated with conductive metal on one side are separated by a small distance “d” 300µm < d < 750µm partially submerged in a beaker filled with an oil of known physical and thermal properties. The oils are chosen based on their ability to absorb heat. The beaker sits on a hot plate that passively heats up the glass plates through the oil and acts as the heat source in the experiment. The method chosen to achieve the heat-transfer process is to pass oil through the glass plates. The oil is being actuated by applying electricity to one of the electrodes while the other is grounded. The oil motion is controlled by a high voltage amplifier in series with a function generator that is attached to the two conductive glass plates. By periodically actuating the oil heat is transferred from the oil to the glass. Temperature data is collected from probes attached to the plates and or placed in the beaker of oil. The data is then interpreted in MATLAB to plot the temperature and record the movement of the oil.
