Patent ID: 7679910

Claim:
A droplet generator for use in a liquid cooling device to cool a heat generating electronic component, the liquid cooling device having a heat absorber for thermally connecting with the heat generating electronic component and a heat dissipater for dissipating heat generated by the heat generating electronic component, the droplet generator comprising: a bottom electrode plate; a top electrode plate hermetically covering the bottom electrode plate; a fluid channel formed between the top electrode plate and the bottom electrode plate, said fluid channel having an inlet adapted for connecting with one of the heat absorber and the heat dissipater, and an outlet adapted for connecting with the other one of the heat absorber and the heat dissipater; two supporting members disposed at two opposite sides of the fluid channel and hermetically supporting the top electrode plate on the bottom electrode plate; and a plurality of control electrodes disposed between the top electrode plate and the bottom electrode plate, the control electrodes being arranged between the inlet and the outlet of the droplet generator, voltages being regularly applied on the control electrodes so as to generate a plurality of fluid droplets and drive the fluid droplets to move from the inlet towards the outlet of the droplet generator.
