Printed Circuit Board Coil Based Electromagnetic Actuator Design For Micro/Milliscale Manipulation

Erdem Doguş AKKUŞ

Trends in nano and micro technologies have directed researchers' concern towards designing small-scale functional systems, i.e., MEMS, NEMS, etc. This study represents a design and implementation scheme for a class of small-scale actuators. Electromagnetic actuators currently used have disadvantages in small-scale applications since they cannot be produced in the desired sizes and compactness due to complex components. Using printed circuit board (PCB) based design strategies, scalable actuators can be produced in a smaller form factor and at a lower cost. The study aims to produce planar PCB ...Daha fazlası

Excessive use of global energy sources causes negative environmental impacts and a reduction in the available energy resources. Therefore, energy efficiency is the main scope of engineering studies. Since household refrigeration accounts for a large portion of the energy consumption rate in buildings, several innovative techniques have been developed to improve the energy efficiency of vapor compression refrigeration systems. Suction line heat exchangers are considered one of these techniques and they are used to avoid the presence of liquid at the compressor and to prevent sweating on the suc ...Daha fazlası
