1. A heat dissipating device, comprising:
a box, comprising a liquid storage part, a liquid-air mixing part, a liquid inlet, a liquid outlet, an air inlet and an air outlet, wherein the liquid-air mixing part is located upon the liquid storage part, the liquid inlet is located upon the liquid-air mixing part, and the air inlet and the air outlet are located on opposite two sides of the liquid-air mixing part;
a flow dispersion layer, disposed in the liquid-air mixing part, having through holes;
a heat exchange layer, disposed in the liquid-air mixing part, having a continuous phase framework and pores;
a fan, disposed outside the box, and connected to the air inlet; and
a pump, connected to the liquid outlet;
wherein a liquid that absorbed heat of a heat source flows into the flow dispersion layer through the liquid inlet; the through holes of the flow dispersion layer disperse the liquid into droplets; the fan introduces air at a temperature lower than a temperature of the droplets into the heat exchange layer through the air inlet; the droplets that flowed into the heat exchange layer exchange heat with the air in the continuous phase framework and the pores, and guide plates disposed on the air inlet and the air outlet guide the air to pass through the heat exchange layer; the air that flowed out of the heat exchange layer flows out of the box through the air outlet; the liquid storage part collects the droplets that flowed out of the heat exchange layer to be heat dissipated liquid; and the pump transfers the heat dissipated liquid to the heat source through the liquid outlet.
