DEVICE FOR HEATING LIQUIDS Russian patent published in 2014 - IPC F24J3/00 

FIELD: energy.

SUBSTANCE: liquid heating apparatus comprises a heat generator comprising a housing having a cylindrical portion and a liquid movement accelerator, designed as a cyclone, a pump connected to the heat source via an injection nozzle, where at least one insert is placed, and a heat exchange system. The insert is formed as a continuous plate along the injection nozzle oriented perpendicular to the ends of the cyclone. The insert in the injection nozzle forcibly expands the jet in its entry into the cyclone, which results in formation of a vacuum region, downstream the compression region, the vacuum again, compression, etc. As we move into the cyclone, collapse and cavitation are formed in turns on each element of the jet flow in these regions, providing hot water or other process fluid.

EFFECT: invention makes it possible to improve heating efficiency and reliability of a fluid device.
