The disclosed technology includes techniques for improving efficiency of heat transfer devices, specifically condensers. An exemplary embodiment provides a device for condensing vapor bubbles comprising a quantity of liquid, a vapor source, and an acoustic transducer. The vapor source can be configured to introduce a plurality of vapor bubbles in the quantity of liquid. The acoustic transducer can be configured to provide acoustic energy to the quantity of liquid such that at least a portion of the acoustic energy is transferred to the plurality of vapor bubbles causing at least a portion of the plurality of vapor bubbles to condense in the quantity of liquid.

Ultra-compact, scalable, direct-contact vapor condensers using acoustic actuation

A preferred embodiment of an atomizing apparatus incorporates a source of heat transfer fluid and an atomizing surface adapted to receive a droplet of the heat transfer fluid thereon. A driver also is provided which is configured to control a vibration of the atomizing surface at a frequency less than ultrasonic so that the atomizing surface forms a spray of atomized droplets from the droplet of the heat transfer fluid. Preferably, the vibration is configured to form, on the droplet, surface waves having a smaller wavelength than a diameter of the droplet, thereby ejecting and propelling the atomized droplets from the droplet. Methods also are provided.
