Patent ID: 7913747

Claim:
A droplet generator adapted for use in a liquid cooling device to cool at least a heat generating electronic component, the liquid cooling device having at least a heat absorber adapted for thermally connecting with the at least a heat generating electronic component and at least a heat dissipater adapted for dissipating heat generated by the at least a heat generating electronic component, the droplet generator being disposed between and communicating with the at least a heat absorber and the at least a heat dissipater and adapted for driving a working fluid to circulate in the liquid cooling device, the droplet generator comprising: a first electrode plate having an array of control electrodes; a second electrode plate hermetically covering the first electrode plate and having an array of reference electrodes crossed over the array of control electrodes; a fluid channel formed between the second electrode plate and the first electrode plate, said fluid channel having outer openings at opposite ends thereof adapted for respectively connecting with the at least a heat absorber and the at least a heat dissipater; and a plurality of superposed areas being formed between the control electrodes and the reference electrodes, voltages being regularly applied on the superposed areas for generating a plurality of fluid droplets and driving the fluid droplets to move along the fluid channel between the outer openings of the opposite ends of the droplet generator.
