MULTISTAGE CAVITATION HEAT GENERATOR (EMBODIMENTS) Russian patent published in 2018 - IPC F24V99/00 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering and can be used for the liquids heating in heating systems, hot water supply and in various areas, where the liquid systems activation, destruction and change in the physical and chemical properties are required. According to the first embodiment, upstream of the suction turbines, the multistage cavitation heat generator on both sides comprises hydrodynamic cavitation mixers, which are rigidly fixed to the heat generator housing, and upstream of the mixers the suction turbines are installed and rigidly fixed on independent shafts, wherein in the mixers narrowing part, the working chambers, branch pipes are inserted at an angle of no more than 45 degrees relative to the drive shaft central axis to the liquid main opposite flow for the disturbing flow supply from the fixed on the rotor disks suction turbines. According to the second embodiment, in the heat generator, into the working chambers branch pipes are inserted at an angle of no more than 45 degrees relative to the drive shaft central axis to the liquid main opposite flow for the disturbing liquid flow supply from the suction turbines, installed downstream of the hydrodynamic cavitation mixers and branch pipes with control valves for air suction at an angle of no more than 45 degrees relative to the drive shaft central axis along the main flow direction for the air suction into the liquid main flow.

EFFECT: creation of devices providing high heating capacity and the liquid heating rate.
