Impingement Cooling Using the Ionic Wind Generated by a Low-Voltage Piezoelectric Transformer
As the consumer demand for smaller, more sophisticated computers grows, the need arises for new air cooling methods that will work in geometries that mechanical fans cannot. Ionic winds (also known as electrohydrodynamic flows) are flows that are produced by the generation of a gas discharge. These flows do not require moving parts to operate, making them attractive for small form-factor device...
متن کاملAnalysis and Design of a Piezoelectric Transformer AC/DC Converter in a Low Voltage Application
steady-state processes in a power PT converter with a halfway two diodes output rectifier are studied. It is shown that such a power converter can operate in two modes: with or without overlap of the conduction intervals of the diodes. The analytical equations and characteristics derived in this study were found to be in good agreement with simulation and experimental results. The study highlig...
متن کاملWind-generated Electrical Energy Using Flexible Piezoelectric Materials
Electrical energy can be harvested from the wind using flag-like membranes (termed piezoelements or bimorphs) composed of flexible piezoelectric materials. The flapping of the membrane caused by the wind induces bending stresses which generate a voltage across electrodes positioned on the surfaces of the material via the piezoelectric properties of the material. The best results to date using P...
متن کاملLaptop Adaptor Using a Piezoelectric Transformer -Drive Circuit Development-
This paper describes incorporation of a piezoelectric transformer into a laptop computer adaptor in order to miniaturize the size and improve the energy utilization. Conventionally, electromagnetic transformer is used in the adaptor for generating the 45W output power. In this study, we show that a multilayer piezoelectric transformer rated 30W output power can satisfy the laptop specifications...
متن کاملDevelopment of heat sink with ionic wind for LED cooling
A heat sink with ionic wind has been developed in this study for a new cooling device of a Light Emitting Diode (LED). The characteristics of the ionic wind using wire to parallel-plate-electrodes were analyzed using the Computational Fluid Dynamics (CFD) technique suggested in this study. Also, the cooling performance of the heat sink applied by the impinging flow of the ionic wind was investi...
