The invention relates to a device for converting thermal energy into pressure energy of a liquid stream and can be used to rotate hydraulic motors, as a water jet installation of a boat or boat.

Energy converters are known comprising an evaporator and a refrigerator partially filled with low boiling liquid, a hydraulic accumulator and a pump chamber with suction and discharge lines, the evaporator and a refrigerator made in the form of separate containers connected by a pipeline, the pump chamber is located in the refrigerator, and the hydraulic accumulator connected to the suction line (see. A. S. USSR No. 1490317, F 03 G 7/06, 1986; 1560784 F 03 G 7/06, 1987).

The closest in technical essence is an energy converter containing a heat pipe with zones - transport, evaporation and condensation, the last of which is filled with a heat-sensitive medium, a heat source, and the pipe through the back pressure valve is connected to the outlet line of the high pressure medium and through the return the valve — with a hydraulic accumulator tank and a refrigerator (see a. S. USSR No. 1569419, F 03 G 7/06, 1988).

A disadvantage of the known energy converter is its low efficiency, power and reliability due to cyclic heating (alternate heating and cooling) of the upper part of the transport zone of the heat pipe. The absence of steam overheating reduces the efficiency and power of the converter, and with cyclic operation, reliability

The goal of the isorethenium is to increase efficiency, power and reliability.

This object is achieved by the fact that in the known device the evaporation zone is in communication with the transport zone through an additional non-return valve, and the upper part of the evaporation zone is communicated with the transport zone through channels with additional back pressure valves placed therein.

The invention is illustrated in the drawing, which shows an example of a specific implementation.

The energy converter contains a heat pipe 1, with evaporation zones 2, transport 3 and condensation 4, the last of which is filled with a heat-sensitive medium 5, a heat source 6. Heat pipe 1 through the back-up valve 7 is connected to the output line 8 of the high pressure medium and through the return valve

9 with a reservoir-accumulator (conditionally not shown). The converter has a refrigerator 10. In addition, the evaporation zone 2 is connected to the transport zone through an additional non-return valve 11, and its upper part to the transport zone is connected by channels 12 to the additional back-up valves 13.

The proposed device works

0 as follows.

When the heat source 6 supplies heat to the evaporator 2 of the heat pipe 1, the medium 5 first heats up and then evaporates, squeezing out the pumped medium 5 from the channels 12 through the valve 13, and then from the transport zone 3 of the pipe 1 through the valve 7 and the outlet pipe 8 and further to the consumer. After squeezing out the entire medium from the pipe 1, the steam starts to come into contact with the cold pipes 10, where it instantly condenses, as a low pressure zone is formed there, then all the steam from evaporation zone 2 will rush there. After a significant decrease in pressure in the pipe 1 under

5 by the action of the differential pressure reservoir-accumulator -heat pipe 1, the check valve 9 opens and the medium 5 begins to fill the pipe 1, its transport zone 3, and then through an additional return

0 valve 11 and evaporation zone 2. At this time, valve 7 is closed. After filling in the evaporation zone 2, the cycle will be repeated.

During operation of the converter, the medium 5 enters the evaporation zone 2 through the non-return valve 11, and the generated vapor leaves the evaporation zone 2 through the back-up valve 13, and the passage through the channels 21 of the steam is additionally heated, expands, and does a great job when leaving the evaporation zone , with high efficiency. The above feature of the movement of the medium 5 and the vapor increases the reliability of filling the evaporation zone with the medium since the upper part of the transport zone 3

5 can be made of material with minimal coefficients of thermal conductivity and heat capacity. This, unlike the prototype, is possible because steam overheating is provided in channels 12.

0 Compared with the prototype, the proposed thermal energy converter has higher efficiency and power, it has higher reliability, because medium inlet

5, the evaporation zone is carried out along one line, and steam is discharged along another line.
