Ultrasonic atomizing cooling apparatus

An ultrasonic atomizing cooling apparatus, comprising:

• a container with working fluid contained therein, said container having an opening formed on an upper surface thereof;
• an ultrasonic vibration device disposed in the working fluid of said container to generate atomized droplets from the working fluid;
• a heat-exchange chamber having a first wall surface, a second wall surface, a third wall surface and a fourth wall surface, said first wall surface being opposite to said second wall surface and said third wall surface being opposite to said fourth wall surface;
• wherein said first wall surface contacts a heat-producing body, said second wall surface is provided with an atomized droplet entrance, and said third wall surface is provided with a vapor exit;
• an atomized droplet passage having an entrance and an exit, said entrance communicating with said opening of said container, said exit provided with a nozzle, which passes through said atomized droplet entrance of said second wall surface of said heat-exchange chamber;
• a vapor passage having a first entrance and a first exit, said first entrance communicating with said vapor exit of said third wall surface of said heat-exchange chamber, and said first exit communicating with said container;
• and
• a heat-dissipating mechanism coupled to said vapor passage;
• wherein the atomized droplets generated in said container pass through said atomized droplet passage and spray onto said first wall surface of said heat-exchange chamber through said nozzle to conduct heat exchange with said heat-producing body, and the atomized droplets become vapor through phase change, said vapor pass through said vapor passage, and said vapor are cooled down to droplets, which flow back to said container.
