Abstract: The cylindrical thermohydraulic device for heating/reheating liquids, comprises a liquid circulating accelerator with an interchangeable conical ring and a pump (1) connected through the forcing side of the cylindrical tube. The lower end of the accelerator is connected to an Archimedes screw (2) linked with a cylindrical tube (3) at an exit of a brake (4). The cylindrical tube is coaxial to the screw and the brake. An open part is directed into the circulation liquid, and is fixed to blade (5) installed on both sides of the brake. The cylindrical thermohydraulic device for heating/reheating liquids, comprises a liquid circulating accelerator with an interchangeable conical ring and a pump (1) connected through the forcing side of the cylindrical tube. The lower end of the accelerator is connected to an Archimedes screw (2) linked with a cylindrical tube (3) at an exit of a brake (4). The cylindrical tube is coaxial to the screw and the brake. An open part is directed into the circulation liquid, and is fixed to blade (5) installed on both sides of the brake. The brake is characterized in hollow cylindrical end of small diameter. The outlet of the brake is formed by a diffuser in which outer diameter is equal to the inner diameter of the tube. The cylindrical tube at entrance of the brake circulates the liquid in vortex form with the maximum temperature. An interaction of the liquid with the blades having small hole hollow cylinder of longitudinal channels inside the cylindrical tube with an effective braking of the current in the diffuser at the exit of the channels. An angle of injection cone of the accelerator in the Archimedes screw is 10-15[deg]. The opening diameter of the accelerator is secured with a power of the pump of 0.8-1.0 mm/kW. The diameter of the injector inlet is carried out by interchangeable conical ring whose surface value is related with the accelerator surface to the connected place. The accelerator length with the conical ring is >= 2. The cylindrical tube length varies in the ratio of 6-13 with the external diameter of the small hole hollow cylinder forming the brake. The surface diameter of the pipe to the braking element and the inlet diameter surface of injection in the Archimedes screw varies with 1-1.5. The internal diameter of the cylindrical tube varies in a ratio of 1.2-1.8 compared to the external diameter of the small hole hollow cylinder forming the brake. The blade length varies in a ratio of 0.7-1.6 of the internal diameter of the cylindrical tube, and the blade is installed radially. The diffuser length varies in a ratio of 0.1-2.0 of the internal diameter of the cylindrical tube. A rectilinear motion of a liquid is transformed into a vortex of the cylinder tube and Archimedes exit having large diameter with hydraulic losses. The vortex of acceleration zone has a low pressure to create hydrodynamic cavitation. The braking of the cylindrical tube circulation transforms the whirling motion of the liquid into a rectilinear motion.
