HEAT AND MASS AND ENERGY EXCHANGE METHOD AND DEVICE FOR REALISATION THEREOF Russian patent published in 2009 - IPC F25B9/04 

FIELD: power engineering.

SUBSTANCE: there is proposed heat and mass and energy exchange method and device, at which, by means of concentric vortex tubes, owing to deformation-shear interaction in intersection zone of side surface layers, there provided is excitation of two and more vortex product flows. External vortex tube is longer than internal one. Along centre line of internal vortex tube, there is installed the first axial displacer forming a vortex-forming annular cavity on the part protruding from internal vortex tube; thereon installed is the second axial displacer forming adjustable annular gap, and with external vortex tube - an acoustic chamber. Pressure chambers are equipped with control valves along the inlet.

EFFECT: use of invention will allow increasing capacity and duration of acoustic excitation, and control of frequency-amplitude performance of acoustic excitation.
