The main disadvantages of known teletrabajo engine are the complexity of the design, due to the presence in the case of the power turbine with rotating shaft and hosts its sealing and complexity of creating a reciprocating motion of the working body, which reduces its reliability and efficiency.
The technical result for the solution of which the present invention is directed, is to improve the reliability and efficiency teletrabajo engine.
The technical result is achieved by the fact that deplorably engine reciprocating motion (TDPD) includes placed in the same housing evaporative chamber, covered inside the wick, the upper end wall of which is covered with strips of porous material, and in contact with the hot environment, separated from it by a partition wall of the condensation chamber, also the inside is covered with a wick, which is a continuation of f is til evaporation chamber, and in contact with the cold environment; and the wick is covered with a sleeve that is installed with a slight gap relative to the upper and lower end walls of the casing, a partition provided with a Central inlet opening, inside the condensation chamber to the center of the end wall attached with valve stem, the portion of the outer surface of the shell, forming a condensing chamber, covered outside of the bellows is rigidly attached to the body with its upper edge, the lower edge of the end wall connected to the inner edge of the bead ring of the tank, the outer edge of the Board which, in turn, rigidly connected with the lower edge of the bellows, and the center with the outer shaft, the United with a working body (not shown in figure 1); the cavity between the bellows and the casing and the steam space of the condensation chamber are connected with each other through tubes passing through holes in the sleeve, the wick and the body.
Based on the proposed TDPD is the 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 the wick and partially filled with the working fluid - carrying heat, which used water, alcohols, halocarbons, liquid metals, etc (Hari the ones VV and other Secondary heat flow meters and environmental protection. Minsk, Either. school, 1988, p.106).
Figure 1-3 shows the proposed TDPD.
Deplorably engine reciprocating motion consists of a casing 1, covered inside the wick 2, covered, in turn, the sleeve 3 mounted with a slight clearance relative to the upper 4 and lower 5 end walls of the housing 1, in which in the direction of steam are: evaporation chamber 6, the inner surface of the end wall 4 which is covered with strips of capillary material 7 connected to the wick 2. There are wall 8 with a Central inlet opening 9, the condensation chamber 10 within which the center of the lower end wall 5 is attached to the rod 11 with a valve 12 for opening and closing the inlet 9, and a portion of the outer surface of the housing 1, forming a condensing chamber 10, is covered outside of the bellows 13, rigidly attached to its upper edge, the lower edge of the end wall 5 is connected to the inner edge of the bead ring of the tank 14, the outer edge of the Board which, in turn, rigidly connected with the lower edge of the bellows 13, and the center rod 15 which is connected with working body (not shown in figure 1); the cavity between the bellows 13 and the housing 1 and the steam space of the condensation chamber 10 is communicated between the FDS is th through tubes 16, passing through holes in the sleeve 3, the wick 2 and the housing 1.
Based on the proposed TDPD is the 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 the wick and partially filled with the working fluid - carrying heat, which used water, alcohols, halocarbons, liquid metals, etc (V.V. Kharitonov and other Secondary heat flow meters and environmental protection. Minsk, Either. school, 1988, p.106).
Offer deplorably engine reciprocating motion is as follows.
Before you start working chamber 6 and 10 TDPD remove the air and pumps the working fluid, which is selected depending on thermal capacity of the cold and hot environments (fitting to remove air and working fluid supply not shown in figure 1) in a quantity sufficient to fill the pore volume of the wick 2 and the annular reservoir fluid 14; then case 1 TDPD is installed vertically so that the evaporation chamber 2 in contact with the hot environment, and the condensation chamber 10 is cold; the annular reservoir fluid 14 was placed horizontally, and in the cold with the standing the valve 12 is tightly closes the inlet opening 9. As a result of heating of the end face 4 of the evaporation of the working fluid in the grooves between the strips of porous material 7, which prevents the formation of steam film on the inner surface of the end face and thus intensifies the process of evaporation (Heat pipes and heat exchangers: from science to practice. Collection of scientific papers. M., 1990). This forms a vapor in the evaporation chamber 2 is pressurized, which, acting on the valve surface 12, rigidly connected through the rod 11 and the end wall 5 with an elastic bellows 13, moves it down, which opens the inlet opening 9 and the resulting steam flows into the condensation chamber 10 and thence through the pipe 16 into the cavity between the housing 1 by a bellows 13, the pressure in which is equalized with the pressure in the evaporation chamber 2, is condensed there by contact of the outer surface of the end wall 5 and the bellows 13 cold environment. As a result, the pressure in the chamber 10 decreases, the bellows 13 is compressed, and the valve 12 closes off the inlet opening 9, and then into the evaporation chamber 6 again begins to increase the pressure. At the same time, the resulting condensate due to gravity flows into the annular reservoir 14, whence it is absorbed by the pores of the wick 2, and under the influence of capillary forces adiabatic working fluid rises to the top wall 4, where will the attached strips of porous material 7, evaporates on the surface of the grooves between them, and the cycle repeats. While the depth of the wick 2 in the condensate in the annular chamber 14 must provide an uninterrupted supply of the working fluid in the evaporating chamber 6 in the interval of the stroke length of the bellows 13, and the width of the gap between the end walls 4, 5 and the edges of the sleeve 3 to the maximum flow rate of the working fluid entering the evaporator chamber 6, and the condensate is discharged from the chamber 10.
Thus, the proposed TDPD provides the possibility of obtaining mechanical energy due to the utilization of thermal energy potential (energy, waste water, waste gases and so on), thermal resources natural sources (solar energy, water, etc) in the form of reciprocating motion.
