Miniaturized liquid cooling device

A miniaturized liquid cooling device comprising:

• a heat absorber;
• a heat dissipater;
• a droplet generator driving a working fluid circulating between the heat absorber and the heat dissipater and dividing the working fluid into fluid droplets when the working fluid flows through the droplet generator;
• and
• a plurality of tubes connecting the heat absorber, the heat dissipater and the droplet generator with each other;
• wherein the droplet generator comprises two sealing blocks hermetically disposed at two opposite ends thereof, the droplet generator having inlet and outlet being respectively defined in the sealing blocks.

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;
• 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;
• wherein the bottom electrode plate defines an elongate tiny fluid slot configured for wicking a fluid segment into the fluid channel;
• and
• wherein the bottom electrode plate defines a fluid storage pool communicating the inlet with an end of the fluid slot.
