The invention relates to mechanical engineering and can be used, for example, as the engine of the aircraft.

A device for converting thermal energy into mechanical work of the Stirling engine.

The disadvantages of the known device should include a complex structure, due to the presence of rhombic mechanism for transmitting the movement of two pistons with complex kinematics of the mutual motion of the shaft of the PTO.

As a prototype of the selected heat pipe, which converts thermal energy into electrical energy.

The disadvantages of the devices of the prototype should include the complexity of the design, due to the presence of the pump for pumping fluid from the condensation zone to the evaporation zone.

A second disadvantage of the known device is a long chain of transformations of one kind of energy into another, at the end of which is thermo-EMF. This fact characterizes the extremely low efficiency of the installation as a whole.

The aim of the invention is to simplify the construction and increase the efficiency of the Converter of thermal energy.

This is achieved by the fact that p is tensator, thermal machine, located between the condenser and the evaporator, and a pump for pumping condensate in the liquid phase from the condenser to the evaporator.

According to the invention the Converter of thermal energy into mechanical work comprises a sealed enclosure filled with fluid from the evaporation zone, transport and condensation, a multi-stage turbine rotor blades mounted on the disk, rigidly associated with the area of transport, and the guide device, rim, two annular magnet, the journal of the turbine, Foundation and additional blades, and the rim is firmly attached to the rotor blades, between the outer surface of the rim and inner surface of the housing is formed of a gap, the vanes of the guide vane installed on the disk mounted on the axle of the turbine to rotate, one of the ring magnets covers vanes of the guide vane and installed with a clearance relative to the housing, and the second ring magnet mounted coaxially with the first gap relative to the outer surface of the casing and secured to the Foundation, while the body is made in the shape of a truncated cone, the base of which is a zone of evaporation, and is mounted for rotation.

On the phenomena of thermal conductivity of the area of transport, which includes a turbine, made of insulating material.

At the Converter fluid in the evaporation zone under the action of continuously applied heat evaporates and enters the rotor blades of the turbine, resulting in the transducer housing receives rotary motion. Passing through the vanes of the guide vane, the coolant is cooled in the condensation zone, transformed into a liquid phase and deposited on the walls of the casing of the Converter of thermal energy.

Due to the rotation of the housing of the transducer, and also taking into account the fact that the transducer housing is made in the shape of a truncated cone, on the particle-liquid mass m acting axial force F2that is directed to the evaporation zone, which can be defined by the formula

F2m2r sin where F is the axial force;

m the mass of the particles of the heat carrier in the liquid phase, the angular velocity of the transmitter;

r the radius of the transmitter in the area of transport;

the angle of taper of the body of preobrazovatelya.

In the area of transport in the gap between the transducer housing and the rim of the impeller of the turbine, and the rim of the guiding apparatus in which densely, and the coolant in the liquid phase from the condensation zone to the evaporation zone. When this liquid coolant in the form of a film attached to the casing of the transducer and the fluid in the vapor state is located between the film and the rim of the impeller and the rim of the guide vane.

To create a gas-dynamic resistance to the flow of the heat carrier in the form of vapour from the evaporation zone to the condensation zone according to the invention the rim of the impeller of the turbine and the rims of the guiding device is made of an annular groove that functions labyrinth seal.

To create a local depression in the zone of inflow of the liquid coolant in the evaporator according to the invention on the rim of rotor blades from the base are made extra blades.

The purpose of the two ring magnets to transmit protivotumanki from the rotation of the impeller of the turbine and the transmitter of the base or body of the aircraft.

As an example, presents a Converter of thermal energy into mechanical work with a single-stage turbine.

The Converter of thermal energy into mechanical work comprises a sealed housing 1 in the form of a truncated cone, partially filled with the heat carrier mounted for rotation around the longitudinal axis. The transducer housing contains 2 evaporative and condensing 3 zones. In the case contains insulating ring 4, which is the element housing and rigidly fixed with evaporative section 5 and the condensing section 6 of the housing.

By insulating ring rigidly secures the impeller 7 of the turbine with the rotor blades 8, covered by the rim 9, with the formation of the annular gap 10 between the insulating ring and the rim of the impeller. Turbine wheel provided with a pin 11, which has the second wheel 12 of the turbine with guide vanes 13 covered by the rim 14 with the formation of the annular gap 15. P magnet installed external ring magnet 16, rigidly associated with the base 17. In the rim of the impeller and an additional turbine wheel includes an annular groove 18. The rim of the impeller of the turbine from the evaporation zone is equipped with extra blades 19.

The Converter of thermal energy into mechanical work is as follows.

When applying heat to the evaporating section 5 and the heat from the condensing section 6 of the housing 1, the fluid in the evaporation zone 2 goes from a liquid to a vapor state and under pressure enters the rotor blades 8 of the impeller 7 of the turbine. After that, the coolant passes through the guide vanes 13 of the second wheel 12 of the turbine and enters the condensing zone 3 of the Converter. Giving some of the heat in the condenser 6, the coolant passes into the liquid phase and deposited on the inner wall of the housing 1 of the Converter. Since the second turbine wheel 12 by means of two annular magnets 14 and 16 are fixed against rotation relative to the base 17, the rotation gets the impeller 7 together with the housing 1 of the Converter.

The coolant in the liquid phase deposited on the walls of the condensation section 6, under the action of the axial component of F2force napravle the La, where it evaporates again.

In order to avoid disrupting the flow of the coolant in the liquid phase on the transport section of the ring groove 18 rims 9 and 14 of the wheels 7 and 12 provide additional hydrodynamic resistance to movement of the counter-flow of the coolant in the vapor state through the annular gaps 10 and 15, and the additional vanes 19 generate a vacuum at the entrance point of the fluid in the evaporation zone 2.

In the proposed technical solution, all four elements of a heat engine, i.e., the evaporator, the condenser, the energy Converter (turbine and pump are enclosed in a single sealed housing, which results in simplicity of construction and reliability of operation of the proposed Converter.

Thermal energy Converter can operate in any orientation in space.

Energy source Converter can serve almost any fuel, including solar energy.

The application of the transducer: side power source in space vehicles; engine aircraft; stationary engines of great power.
