Effect on swept volume on cooling using pumping mechanism based device / Noor Aishah Rabion

Synthetic jet had been used as electronic cooling method that used diaphragm movement to initiate air flow through orifice. Synthetic jet was designed to overcome the problem of heat generated due to the increasing number of electronic component in a device. Miniaturization of electronic device has...
