METHOD OF HEAT RELEASE IN LIQUID AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC F24J3/00 

FIELD: heating systems.

SUBSTANCE: invention refers to power engineering. In method of heat release in liquid, which includes liquid flow acceleration, with its being divided into several flows, their being swirled in channel, deceleration of flows by collision of opposite flows and integration into common flow; flow is divided into 8 pairs of swirl (vortex) flows, 2 pairs above each other; swirling is performed by means of Archimedean screws, at outlet of which each flow is directed to pulsating chamber, thus creating hydraulic impacts by means of breaker on opposite vortex flows so that cavitation with resonant flow excitation is created; then opposite swirl flows at the opening of pulsating chamber are subject to high-voltage electric pulse low power discharge upon condition of forced negative pressure of medium, which is performed with impeller of centrifugal pump, and are combined in acoustic chamber with possibility of additional acoustic resonant excitation. Invention also refers to cavitator - heat generator, which includes channels with swirl devices, at the outlet of which there installed is plenum chamber made with possibility of collision of swirl flows, and flow collection device. Cavitator is equipped 16 with longitudinal channels with swirl devices made in the form of Archimedean screws located in 2 pairs above each other, channels themselves are made with possibility of energy storage of hydraulic impact pulse; at that, plenum chamber is made in the form of pulsating chamber with breakers with possibility of successive connection of pairs of swirl flows to interaction with each other; at that, cavitator is equipped with impeller of centrifugal pump, which is installed with possibility of negative pressure of medium, and flow collection device is made in the form of acoustic chamber.

EFFECT: increasing efficiency and intensification of heat-and-mass-and-energy exchange owing to combined interaction method which includes resonant excitation of swirl flows, as well as hydraulic impact and electric pulse impact.
