This paper proposed a novel liquid cooling system for portable electronic equipment such as a laptop computer. This system includes multiple micropumps serially arranged in a cooling pipe. The moving part of the micropump is composed of a permanent magnet and an elastic plate. When a solenoid coil wound around the cooling pipe generates an alternating magnetic field, the magnet oscillates due to magnetic torque and the elastic plate induces the flow of the coolant. At first the pumping properties of the single and serially arranged micropumps were evaluated. Next, the liquid cooling system was fabricated and tested. As a result, the first prototype has successfully demonstrated good cooling performance.
