The invention consists in that the hydrodynamic heater containing cylindrical body, the end of which is set accelerator movement of the coolant inlet pipe, a pump, "shirt", the overflow drain from the heater's housing in the jacket and the outlet, further provided with resonators placed around the circumference of the cylindrical body in two or more rows with shift angle at a given distance from the accelerator movement of the carrier and between them and turbulization made in the form of combs from a metal strip with a thickness of 0.1-0.3 mm with 10 or more teeth, spun 360 degrees, collapsed in the block on the inner diameter of the heater's housing and installed in the near wall region of the housing (R÷0,9 R) at a given distance from the accelerator movement of fluid between itself and from the resonators. This embodiment of the heater allows you to more fully convert the energy flow into thermal energy which belongs to the field of heat, in particular to devices for heating the liquid, and can be used in heating systems of buildings and structures, vehicles, heating water for industrial and domestic use, drying and pasteurization of agricultural products. In addition, the device can be used for heating directly in the pipeline viscous liquids like oil to reduce viscosity and improve its rheological properties. Hydrodynamic heater is a source of thermal energy derived from occurring in the system liquid - installing the physical processes that occur during rotational and translational movement of the fluid and cavitation processes in the system under the influence of external forces.

Electric pump unit is provided with the pressure and flow of coolant, which when moving within the proposed design of the hydrodynamic heater is heated to a predetermined temperature.

The level of technology

Known heat pump device using the change of physico-mechanical properties of the medium, in particular pressure and volume to produce heat.

In known devices as a medium can be used, narimasa thermal energy, for reducing the cost of electricity to produce heat.

Well-known heat pump acting as a heat source, the working medium is water, comprising a housing in the form of sealed spherical vessel filled with the working environment located in its heat exchanger network pump, providing compression environment inside the supply and return line, transporting heat to the consumer, equipped with shut-off valves.with. THE USSR №458591, F 25 29/00, 1972).

The main drawback of the heat pump is very high working pressure in the case, which is about 1000 ATM. Such operating parameters of the installation have high requirements for strength of body parts, shut-off valves and piping, which leads to increased cost of installation.

In addition, the use of such an installation for heating of residential premises is dangerous due to the high working pressure.

Another known device is a heat generator described in the patent of Russian Federation (RU) 2045715, CL F 25 D 29/00, 10.11.95.

According to this patent, in the heat, having a cylindrical body with a portion set accelerator fluid motion, made in the form of a cyclone is otepaeae the cyclone mounted brake unit. For the braking device in the cylindrical part of the body has a bottom with an outlet that communicates with the outlet pipe, coupled with the "cyclone" by the bypass pipe, and the connection is made at the end of "cyclone", opposite the cylindrical part of the casing and coaxially with it. The brake device is made of at least two radially spaced ribs secured to the Central sleeve.

Due to the fact that the body of the boiler is equipped with a cyclone, the working fluid under pressure tangentially enters him and moves in a spiral. The flow of the liquid takes on the character of the vortex, its velocity increases, and it gets in the cylindrical part of the housing, the diameter of which is several times the diameter of the injection hole, and then, in the brake device. This constructive embodiment of the casing allows to reduce the speed and pressure of the environment, in accordance with the laws of thermodynamics changes the mechanical energy of the fluid, aimed at increasing its temperature.

Additional brake device installed in the bypass pipe, increases the efficiency of heating the liquid. The difference giving the of Cusa and the bypass pipe provides the prevalence of hot fluid flow over the cold. The bypass pipe provides pripuskanie fluid from the body heat source in the outlet in case of blockage of the outlet, as well as surges of fluid pressure in the system.

A disadvantage of the known device is the decrease in the intensity of heating of the coolant by reducing the rotation speed of the stream as it is removed from the "cyclone". In addition, there are additional heat loss in the bypass pipe, and a hydrodynamic losses due to the small diameter and large length of the overflow pipe. All this reduces the efficiency of the boiler as a whole.

The prototype of the present invention may be a device (Vortex heater), described in patent RU 2129689, 6 F 25 29/00, according to which a vortex heater, containing the first (inner) membrane, with one side (end) of which is set accelerator of the fluid that is made in the form of "cyclone", the inlet of which is intended for connection to the pump, and the outlet, according to the invention provided with an additional (outer) shell located around the first, at least one spiral channel, located between the shells, and means supplying fluid uskoritel of the fluid.

Means providing fluid flow from the first shell of the spiral channel can be made in the form of cracks in the first shell, located at its end opposite the accelerator fluid. Spiral channels can be formed by steel tape wound on the first (inner) shell with a specified step. In the first shell at a given distance from the accelerator of the fluid set screw swirlers.

The disadvantages of this device include the application for restoration of turbulence in the coolant flow screw swirlers that slightly increasing the heat transfer, significantly increase the hydraulic losses (7-8 times), and use for heat, in the end, only the forces of viscous friction, which reduces the efficiency of the boiler as a whole.

The technical result from use of the present invention is a better use of the energy flow of the coolant that is converted into heat, due to the installation in the near wall region of the housing of the generator (R-0,9 R), where it is converted to heat up to 60% of the energy flow, turbulization and placement on the generator housing resonators, creating additional Tim the release of thermal energy.

For example, when setting 10 turbulization, representing a comb from a metal strip (=0,1-0,3 mm) with 10 or more teeth, spun 360 degrees and collapsed in a block on the inner diameter of the casing of the heater, the heat transfer is increased by 20-100% increase in hydraulic resistance only up to 2.5 times.

Placing the housing of the generator resonators with resonant frequencies of the order of 13 to 17 kHz, made in the form of deaf sleeves installed by diameter groups placed along the body at predetermined distances from the "cyclone" and between them, increases the criterion Nusselt more than 5 times compared with the conditions of natural convection.

The invention

Hydrodynamic heater is a passive element of the heating system, in which flow all the processes efficient conversion of the energy of motion of fluid into thermal energy. The process of obtaining energy in this design consists of two components:

1. The dissipation of the vortex flow generated by a cyclone and supported by turbulization due to the forces of viscosity and transition of this form of ordered motion in disordered (teplovizionnykh processes in papilonaceae with further collapse of bubbles of steam, accompanied by the release of thermal energy.

The energy source is an electric pump unit that creates the necessary pressure and provides the specified flow.

The present invention allows to:

- create and maintain all the active site of the body heat source of rotational and translational turbulent flow, in which there is intense heat,

- to initiate the flow of fluid ultrasonic vibrations in crystals, when exposed to which the coolant is saturated with vapor bubbles, the process of destruction which due to flowing of the cavitation process is also accompanied by intense heat.

This is due to the fact that the hydrodynamic heater containing cylindrical body of radius R, one side of which is installed the accelerator movement (such as "Cyclone" or axial blade accelerator) connected to the pump body according to the invention is equipped with a number of turbulization installed in the internal cavity of the housing in the region (R-0,9 R), at a specified distance from the accelerator movement and between itself and one or more series resonators, in which diiodoethane takes coolant, emitted through located at the end of the body of the blank flange of the overflow drain, sends it along the speakers in the jacket cavity, the heating in the proceeding in them cavitation processes, and carries away the heat next to the exhaust pipe.

The invention is illustrated by the drawing, which shows a General view of the hydrodynamic heater.

Hydrodynamic heater comprises a cylindrical housing 1, the jacket 2, a blank flange 3 located at one end of the housing 1. On the other Highlander body set accelerator movement of the carrier 5 (made in the form of a "cyclone" or accelerator type, designed to twist (torsion) of the coolant in the housing 1. In the near wall region of the housing (R-0,9 R) installed turbolister 7 supporting the turbulent nature of the flow of coolant throughout the working portion of the housing of the hydrodynamic heater. The diameter of the cylindrical body at a given distance from the cyclone in two or more rows with shift angle welded liner resonators 4, in which a moving stream of fluid excites ultrasonic vibrations.

The inlet 6 of the cyclone is designed to connect nagareboshi holes 8 for Araucania fluid flow from the housing 1 in the jacket 2.

In the left (drawing) part of the “shirt” from "cyclone tangentially in the direction of rotation of the carrier is welded to the outlet 9, which is intended for connection to the pumping pump or directly to the consumers of heat.

Hydrodynamic heater works as follows.

The pressure created by the pump (not shown) on input "cyclone" 5, whirls of the stream of fluid entering the housing of the hydrodynamic heater 1. Heat generating vortex flow of the coolant passing through turbolister 7, is served at the end of the housing of the hydrodynamic heater 1 and the path of movement excites ultrasonic vibrations in the resonator 4, under the action of ultrasonic vibrations, the fluid becomes saturated with vapor bubbles. In the proceeding of cavitation, the bubbles cease to exist, allocating a large amount of heat that is carried away by the coolant, which pass through holes 8 is discharged into the jacket 2, washes the body of the resonators 4, depriving them of heat, and is heated to a higher temperature. The fluid moving along "shirt" to the exhaust pipe, partially sucked by the feed pump from the "shirt" and from the take place the fence part of the liquid in the heating system directly from the output pipe 9 and the inlet pipe 6 "cyclone" branch through tees or creating heat exchanger, discharging heat from the "shirts" 2. One hydrodynamic heater is a module. For more power modules are combined into assemblies with the selection and installation of pumps corresponding performance.
