HYDRAULIC HEAT-GENERATOR Russian patent published in 2006 - IPC F24J3/00 

FIELD: heating engineering, particularly devices for liquid heating used in building heating and water supply systems and in other fields.

SUBSTANCE: hydraulic heat-generator comprises inlet swirling device, vortex tube and heated liquid discharge pipe. Vortex tube and heated liquid discharge pipe are arranged from both sides of inlet swirling device. Vortex tube has body connected to inlet swirling device. The heat-generator additionally has slot diffuser connected to vortex tube body and provided with axial channel located in central slot-diffuser part. The axial channel is coaxial with vortex tube interior and is communicated with it. The slot diffuser is also provided with coaxial (annular) channel communicated with vortex tube interior from the first channel end and with axial channel from another end. Slot diffuser is provided with blades located in annular channel. The blades are radial or have outlet edges twisted so that blade edges extend at an angle to radial direction. The blades reverse liquid flow.

EFFECT: increased efficiency due to intensified energy conversion.
