FLUID HEATING DEVICE Russian patent published in 2015 - IPC F24J3/00 

FIELD: heating.

SUBSTANCE: in fluid heating device, comprising a cylindrical housing with a cyclone and a flow accelerator in its lower part, a braking device in the upper part, behind which a bottom with an outlet opening is located, communicating with an outlet tube which is connected through the bypass tube to an end of the cyclone, in the upper part of the housing a tube is mounted coaxially and with a radial clearance to the outlet opening, which connects the cavity of the cylindrical housing with the atmosphere. The tube plant, which connects the workspace with the atmosphere, increases the efficiency of heating due to bleeding of air escaping from the hydraulic fluid and thus creating more favourable conditions for the passage of sound wave and more active development of acoustic cavitation.

EFFECT: increased efficiency of heating fluid and enhancement of technological properties.
