H02N 3/00, 1940].

The disadvantages of the known devices are cumbersome construction and substantial expenditure of energy to drive the circulation pump, which reduces its effectiveness.

Closer of the present invention is deplorably electrostatic generator, which includes: a casing consisting of a shell, capped at both ends of the hot and cold walls made of a dielectric material and placed inside a shell coaxially of the casing so that between its upper end and the hot wall, the bottom end and the cold wall has gaps, communicating with the channel (area) transportation of steam, forming the evaporation zone and condenses and; vertical U-shaped wall made of dielectric material, transport dividing the area into two equal-size compartments filled with wicks made of different electrochemical characteristics of porous materials, allowing to obtain a positive or negative charges in the working body, the collectors of positive and negative charges, provided with external terminals, and as the working fluid is used dielectric fluid [RF Patent №2327055, Ál. H02N 3/00, 2008].

The main disadvantages of known teletrabajo electrostatic generator are the complexity of the installation, the required size of the gaps between the ends of the casing and the hot and cold walls, the necessity of setting two different compartments with different electrochemical properties placed in them wicks, which complicates its design and modes of operation, limits the scope of its application and ultimately reduces its efficiency and reliability.

The technical problem solved by the invention is to increase the efficiency and reliability teletrabajo electric element.

The technical result is achieved in talocrural electric element, which includes a housing made of dielectric material and consisting of obechi and, plugged from both ends of the hot and cold walls made of a dielectric material; a casing made of electrically conductive material placed inside the shell coaxially aligned so that its top and bottom sides are made of jagged around the perimeter and close the tops of the teeth to the inner surfaces of the hot and cold walls to form between the teeth of triangular holes, communicating with the area transportation vapor, forming a zone of evaporation and condensation, the annular space between the shell and casing is filled with a wick made of a porous material with a homogeneous electrochemical characteristic, in turn, filled with the working fluid dielectric, and the upper and lower ends of the casing are connected by cables with the upper and lower outer terminals.

Based on the proposed TEE is the ability of the dielectric fluid to be electrified when moving through pipelines, and especially through the porous walls, in which the amount of current electrification may increase by several orders of magnitude [Art and other Electrification of liquids and its prevention. - M.: Chemistry, 1975, p.15-25], as well as high efficiency of heat transfer in heat pipes, which are divided into three sections: the zone of evaporation (heat supply), the adiabatic zone (heat transfer) and the condensation zone (exhaust heat), covered inside with a wick made of a porous material is but partially filled with the working fluid (liquid) - carrier heat, which used water, alcohols, and other organic liquids, freon, liquid metals, etc [HIV and other Secondary heat flow meters and environmental protection. - Minsk: Enter. school, 1988, p.106].

Offer TEA works as follows. Before you begin from the housing 1 TTEE remove the air and pumps the working fluid is a dielectric with a specific electric resistivity of not less than (10-12) Ω·m, which is also selected depending on thermal capacity of the cold and hot environments (fitting to remove air and working fluid supply figure 1-2 not shown), in the number of larger pore size of the wick 12 by the amount of steam condensate occupying the volume of the zone transportation vapor 8. Terminals 15 and 16 connect with the consumer current, after which the housing 1 TEA set so that the hot wall 3 will become hot, and the cold wall 4 with cold. As a result of heating of the hot wall 3 in the evaporation zone 9 the evaporation of the working fluid produces steam, which passes at high speed through the area transportation vapor 8, enters the condensation zone 10, is condensed there by contact of the outer surface of the cold wall 4 with the cold environment, then the resulting condensate dielectric liquid is absorbed p is Rami wick 12 through the gaps triangular holes 7 and under the influence of capillary forces and evaporation in the evaporation zone 9 adiabatically transported through the pores of the wick 12 (manufactured for example, organic fibers, where the liquid is electrified with the acquisition of positive and negative charges are collected on the casing of the collector 5, creating a potential difference, and through wires 13 and 14, the terminals 15 and 16 is supplied to consumers, and raredisease fluid through the triangular gap 7 is fed to the evaporation zone 9, where the above-described evaporation process and the cycle repeats.

Thus, the proposed TEE provides the ability to generate electric energy by utilization of thermal energy potential (energy, waste water, waste gases and so on), thermal resources natural sources (solar energy, water, etc), which ensures its high efficiency in various sectors of the national economy.

FIELD: control of temperature of spacecraft and their components.

SUBSTANCE: proposed method includes measurement of temperatures in spacecraft temperature control zones, comparison of these temperatures with high and low permissible magnitudes and delivery of heat to said zones at low limits. Heat is delivered by conversion of electrical energy into thermal energy. Power requirements are measured at different standard time intervals of spacecraft flight forecasting orientation of its solar batteries to Sun. Magnitude of electric power generated by solar batteries is determined by forecast results. Measured magnitudes of consumed electric power are compared with forecast data. According to results obtained in comparison, flight time is divided into sections at excess of energy generated by solar batteries over consumed power, equality of these magnitudes and shortage of generated energy. High magnitudes of temperature are maintained at excess energy sections by conversion of difference of generated energy and consumed energy into heat. In case of reduction of generated energy in the course of changing the orientation of solar batteries on Sun, temperature in these zones is reduced to low limits at simultaneous equality of energies. In case of further increase of generated energy, temperature in said zones is increased to high limits at equality of energies. Then, in the course of change of generated energy, temperature correction cycles in temperature control zones are repeated.

EFFECT: avoidance of excess of consumed energy above generated energy of solar batteries.
