The invention relates to the field of heat engineering, can be used for the direct conversion of thermal energy into electrical energy, for example, in sea buoys, and is an improvement of the well-known pipe by author. St. No. 1177647.

The purpose of the invention is to intensify the process of converting thermal energy into electrical energy.

The drawing shows the proposed heat pipe, a general view.

The heat pipe comprises a housing 1 with evaporation zones 2 and condensation zones 3 and a steam channel 4, a tubular insert 5 installed along the housing axis with the ionizer 6 and the collector 7 of electric charges placed above one another. The condensate collector 8 located in zone 3 is connected via a tube 9 with a nozzle 6. A transverse partition 10 separates the steam channel 4 between the condensation zone 3 and the tubular insert 5 into sections, the top of which is connected to the cavity of the tubular insert 5 below the collector 7 electric charges using a pipe 11. The collector 7 of electric charges is divided into two parts by a dielectric longitudinal partition 12 forming channels with a tubular insert 5, and electrodes are installed between the collector 7 and the nozzle 6 at the channels entrance. 13, each of which is electrically connected to a part of the collector 7 located on the other side of the partition 12. The electrodes 13 are covered with electrets 14 with homozar of opposite signs.

Electrohydrodynamic heat pipe works as follows.

When heat is applied and removed in the evaporation zones 2 and condensation zones 3, respectively, heat and mass transfer occurs with a change in the state of aggregation of the coolant. The vapor from the evaporation zone 2 flows through the nozzle 6 into the tubular insert 5 and through the pipeline 11 enters the condensation zone 3. The condensate from the condensate collector 8 through the tube 9 enters the nozzle 6 and further into the zone 2 of evaporation. Appropriate selection of the flow resistances of the contour channels prevents the circulation from being disturbed. The condensate passing through the nozzle 6 is dispersed by steam and electrified. The resulting neutral drops in the field created by the electrodes 13 are destroyed by oppositely charged ones. Load bearing

the droplets in the field are displaced and the jet of dispersed condensate is positive on the side of the negative electrode 13 and negative on the side of the positive. The longitudinal septum 12 divides it into two oppositely charged streams. One of these streams gives up its charge to one part of the collector 7, the other flow to the other part. The electrodes 13 may be a flat capacitor that creates a uniform field. The collector 7 can be made of metal mesh. Electrical energy is transmitted to the consumer by means of high-voltage leads 15 connected to parts of the collector 7.

To start the electrohydrodynamic converter, the polarity of the electrodes 13, which initially occurs due to the random distribution of charges in the dispersed coolant flow, is required. But the coating of the electrodes 13 with electrets 14 accelerates the start of the electro-hydrodynamic converter and predetermines the polarity of the high-voltage inputs 15 in advance. It is not necessary to connect the electrodes 13 to the collector 7 if electrets are used.

As a heat carrier, the usual refrigerant 113 for heat pipes can be used.

The electrohydrodynamic heat pipe was an autonomous device capable of converting low-grade heat (for example, heat of the seas and oceans) into electrical energy. The absence of moving parts creates a long service life of the device, which can serve as a source of electrical power for installations located at a distance from the powerful electricity producers (for example, for marine navigation buoyers).
