The heat exchange system includes a closed loop 1, which consists of a primary heat exchanger channel 2, device pumping fluid 3, the auxiliary heat exchange channel 4 and channel 5 coolant connecting the heat exchange channels 2 and 4. The feed channel of the heat carrier in the form of a channel with capillary wall 6, overlying the channel. Capillary wall contains IU is greater least one capillary microchannel 7. Pumped by the coolant circuit 8 may be a separate plots or 9 pairs, or vapor-liquid environment 10, or liquid 11. Vapor-liquid medium 10 consists of steam bubbles 12 and liquid formations 13. The pumping device carrier 3 is made with the possibility of removal of the heat carrier in the form of steam or vapour environment with one of the heat exchange channels and pumping of the fluid into a vapor or vapor-liquid environment with a higher pressure in the other of the heat exchange channel.

Consider the operation of the device for the case when the circulation of the coolant in the loop is clockwise, in this case, the main heat-exchange channel functions as a steam generator (this is the case just considered figure 1). So basically the heat exchange channel is in the process of vaporization, this heat is supplied (shown in figure 1 by the arrow-strip). As a result of vaporization steam or vapor-liquid environment, which diverted device for pumping the coolant. Then the fluid from the pumping device in the form of steam or vapour environment with higher pressure is fed in the auxiliary heat exchange channel, where the condensation process. From the auxiliary heat exchanger coolant channel h is cut channel coolant, made in the form of a channel with capillary wall, overlying the channel, is fed to the main heat exchange channel. When this channel coolant provides a uniform flow of fluid from a region of higher pressure to an area with lower pressure due to the interaction of the menisci bubbles 14 15 overlying the cross-section of the capillary microchannel, with the inner surface of the capillary microchannels capillary walls of the feed channel. Here and below we consider the case of wetting by the fluid of the inner surface.

Design of heat transfer systems can be designed in such a way, as well as the quantity of the charged fluid in the heat exchange system may be such that during operation of the heat exchange system in the implementation process of condensation in one of the heat exchange channels, for example, in the auxiliary heat exchange channel, the resulting column of condensate passes through the capillary wall of the feed channel in the main heat exchange channel as a whole, not filling completely the volume of the internal cavity of the main heat-exchange channel (i.e., not violating processes of evaporation and vapour transport in the area from the main heat exchange channel to the pumping device). This mode of operation is satisfactory. Pronichev which of the pair is already resistance, defined by the interaction of the meniscus with the inner surface of the capillary microchannels capillary walls. In this case, for sufficiently small transverse dimensions of the capillary microchannels pairs may not be skipped. Thus preventing breakthrough of hot steam mass in the main heat exchange channel, which functions as an evaporator and in which the pressure (temperature) is lower than in the auxiliary heat exchange channel functioning as the condenser.

Design and refill can be such that education in the process of condensation in the auxiliary heat exchange channel of the liquid-vapor environment. The capillary wall of the feed channel in this case also resists the flow environment, which is determined by the force of the meniscus interaction of bubbles with the inner surface of the capillary microchannels capillary walls. Bubbles can pass through the capillary wall, if their cooling in the area near the exit of the bubbles in order to reduce the volume of bubbles (possibly down to zero), then the operation of the feed channel becomes more efficient.

If in the area before the capillary wall enters the environment without bubbles, the capillary wall has a resistance to flow only through forces Vascos is I.

From the above it is clear how the device operates, when the main heat exchange channel functions as a condenser, and an auxiliary heat exchange channel as a steam generator.

Device for pumping fluid can be accomplished with the possibility of pumping in either direction. Due to this, the main heat-exchange channel can function either as a generator or as a condenser. During operation of the primary heat exchange channel as the capacitor of the auxiliary heat exchange channel may function as a steam generator.

Device for pumping fluid may be in the form of channel pump 16 (figure 2) with the capillary wall 17 overlying the channel, and is also equipped with a thermal device 18 which has a capability to perform at least one of the two modes. The first mode of operation consists in the removal of heat from the facing to the main heat exchange channel surface 19 of the capillary walls and/or from the layer 20 of the capillary walls adjacent to this surface, and applying heat to the facing the auxiliary heat exchange channel surface 21 of the capillary walls and/or to the layer 22 of the capillary walls adjacent to this surface, and the second mode of operation is the removal of heat from facing in pologitelno heat exchange channel surface 21 of the capillary walls and/or layer 22 of the capillary walls, adjacent to this surface, and applying heat to the facing to the main heat exchange channel surface 19 of the capillary walls and/or to the layer 20 of the capillary walls adjacent to this surface. The heat device can also be made with the possibility to carry out simultaneously on both surfaces 19 and 21 of the capillary walls, facing to the main and auxiliary heat exchange channels, and/or in layers 20 and 22 adjacent to these surfaces, the processes of heat addition or rejection. When the operation of thermal device in the first mode, the exhaust steam or vapor medium from the primary heat exchange channel is through the process of condensation is directed to the main heat exchange channel surface 19 of the capillary walls or layer 20 of the capillary walls adjacent to this surface. After carrying out the process of condensation of the coolant is transferred through the capillary wall. Due to heat vaporization occurs recourse to auxiliary heat exchange channel surface 21 of the capillary walls or layer 22 of the capillary walls adjacent to this surface. Due to capillary forces created by the meniscus formed by the pumping of fluid into a region with Bo is its high pressure. The steam produced is transferred into the auxiliary heat exchanger channel.

Heat the device 18 can be accomplished through the use of thermoelectric module 23 (figure 2), with one surface of junction 24 of thermoelectric module are connected in thermal contact 25 with the surface 19 of the capillary walls, facing to the main heat exchange channel, or with a layer 20 adjacent to this surface and the other surface of junction 26 of thermoelectric module are connected in thermal contact 27 with the surface 21 of the capillary walls facing the auxiliary heat exchange channel, or with a layer 22 adjacent to this surface.

In the heat exchange system can be installed piping 28 (2)connecting the auxiliary heat exchange channel with capillary wall channel throughput. In the pipe 28 can be installed capillary wall 29 (2), and this capillary wall may occupy the entire internal volume of the pipeline. This allows in case of operation of the auxiliary heat exchange channel as a condenser to direct a portion of the condensate directly to the capillary wall and thereby increase the efficiency of the device by reducing the consumption of cooling capacity.

The capillary wall in the feed channel can be set is Lena next to the auxiliary heat exchanger channel (shown in figure 2). In this case also increases the uniformity of feed of condensate in the main heat exchange channel. The capillary wall in the feed channel may occupy the entire internal volume between the main and auxiliary heat exchange channels. Figure 3 shows a plot of 30 between the main and auxiliary heat exchange channels. This whole area can be occupied by the capillary wall 6. In this case also increases the uniformity of feed of condensate in the main heat exchange channel.

Part 31 of the capillary walls of the feed channel may be connected in thermal contact with a part of the main heat-exchange channel (figure 3). This allows you to feed in the main heat exchanger chilled coolant channel; in this case also increases the efficiency of the feed channel, as it eliminates evaporation before the main heat exchange channel, which can lead to useless displacement of fluid from the main heat exchanger channel.

Part of the inner surface of the main heat exchange channel may be covered with a capillary structure 32. This improves the heat exchange system when the operation of the primary heat exchange channel as a steam generator.

The capillary structure of the main heat exchange channel may be connected capillary bridge 33, predstavlyayushie is a capillary structure, with the capillary wall of the feed channel. This improves the uniformity of the coolant in the primary heat exchange channel when it is functioning as a generator.

Part of the flow channel of the coolant may be connected in thermal contact with a part of the capillary walls of the channel throughput, and connection of the heat contact portion of the feed channel and part of the capillary walls can be arranged according to the scheme of the counter. Figure 4 shows that this can be realized, in particular, if the channel coolant run passing through the capillary wall of the channel throughput. Figure 4 shows that the connection thermal contact surfaces of the junctions of thermoelectric module with the surfaces of the capillary walls, converted to the corresponding heat exchange channels, or layers adjacent to these surfaces can be accomplished by making the grooves 34 and 35 on part of the surface of the capillary walls 17, which is connected with the inner surface of the housing channel 16. At site 36, the portion of the flow channel of the coolant are connected in thermal contact with a part of the capillary walls of the channel throughput. This embodiment of the channel of pumping and feeding channel can improve the efficiency of the heat exchange system by reducing consumption kholodoproizvodstva the major.

Device for pumping fluid may be connected in series evaporation-condensation heat exchangers 37 and 38 (figure 5) located between the channel displacement 39 consisting of two capillary walls 40 and 41 overlying the channel, and is also provided with attachment 42 for the supply and/or removal of heat in areas of the capillary walls of the channel displacement, namely, the layers 43, 44, 45 and 46. Between the capillary walls have a cavity 47; there are also areas 48 (located between capillary partition 40 and evaporation-condensation heat exchanger 38) and 49 (located between the evaporation-condensation heat exchanger 37 and capillary wall 41). The device also includes a thermal device 50 that is designed to remove heat from one evaporation-condensation heat exchanger and heat to another evaporation-condensation heat exchanger and Vice versa. As thermal device can be used thermoelectric module. Device for pumping fluid can provide pumping of fluid in either direction. Describe the way in organizing the brine clockwise; in this case, the secondary heat exchange channel 4 functions as a condenser, and the main heat-exchange channel 2 can operate the work as a steam generator. Let's start with stage inlet of the coolant from the field 49 in the cavity 47 (this stage of the work as represented on figure 5). During this stage, the coolant from the area 48 under the action of the pressure of the vapors formed in the capillary microchannels layer 43 of the capillary walls 40, is transferred to the evaporation-condensation heat exchanger 38, where it is the evaporation in the heat supply from the heat of the device 50. From the evaporation-condensation heat exchanger 38, the coolant in the form of vapor or vapor-liquid mixture is transferred into the auxiliary heat exchanger channel 4 and is condensed; then the flow rate through the flow channel 5 is fed to the main heat exchange channel 2, where evaporation occurs. Next, from the main heat exchange channel, the heat transfer medium is transferred to the evaporation-condensation heat exchanger 37 where condensation occurs as a result of heat dissipation device 50. The brine from the evaporation-condensation heat exchanger 37 is fed into the channel displacement, and it is filled through capillary wall 41 into the cavity 47. At the stage of push (this stage is not shown) the fluid from the cavity 47 is displaced through the capillary wall 40 in area 48, it occurs under the action of the pressure of the vapors formed in the capillary microchannels layer 45 of the capillary walls 41. P and this coming from the evaporation-condensation heat exchanger 37, the fluid accumulates in the area 49. The flow of fluid from the cavity 47 in the region 49 is prevented due to the formation of inclusions vapor in the layer 45 located on the side of the cavity 47. This may continue the processes of evaporation in the evaporation-condensation heat exchanger 38, condensation in the heat exchange channel 4, the steam in the heat exchange channel 2 and condensed in the evaporation-condensation heat exchanger 37. Then move to the stage of filling. In the process of work there is an alternation of the above stages.

Heat exchange system can be equipped with a thermal device 51 (6), made with the possibility to carry out a supply of heat to the facing to the main heat exchange channel surface 52 of the capillary walls of the feed channel or to a layer 53 of the capillary walls adjacent to this surface, and/or heat is removed from the facing to the main heat exchange channel surface 52 of the capillary walls of the feed channel or layer 53 of the capillary walls adjacent to this surface. With such design, construction, without changing the direction of circulation of coolant through the circuit, it is possible to arrange the operation of the primary heat exchanger channel either as a generator or as a condenser. Let's start the description of the work when in the heat exchange channel 2 is in the process of proobraz the deposits (figure 6 are not reflected this stage). For example, providing on the surface 19 or layer 20 temperature +5°With (numeric values are purely illustrative), and on the surface 21 and the layer 22 temperature +40°With that you can make in the auxiliary heat exchange channel 4 condensation at a temperature of +38°and in the heat exchange channel 2 evaporation at a temperature of +7°C. the Heat exchange channel 2 at this point provides cooling of the object 54, which is with a heat exchange channel 2 in thermal contact. At this time, the feed channel functions as a device for pressure relief and uniform feeding of the coolant. Using thermal device 51 can be discharged heat from the surface 52 of the capillary walls or from layer 53 adjacent to this surface. Then in the second stage (this stage is shown in Fig.6) using this design it is possible to carry out the condensation process in the main heat exchange channel 2. For example, providing on the surface 19 and the layer 20 temperature +15°and on the surface 21 and the layer 22 temperature +50°you can exercise in the heat exchange channel 4 condensation at a temperature of +48°C. Providing a heat input to the surface 52 or to the layer 53 at a temperature of +50°With you in the heat exchange channel 2 to carry out the condensation at a temperature of +48°C. the Heat exchange channel 2 in this momentously heating of the object 54. At this time, the feed channel functions as a device for generation of steam.

Closed circuit 1 can be made consisting of the auxiliary heat exchanger channel 4 and at least two parallel lines (7), for example, of two lines 55 and 56, each of which consists of a flow channel of the fluid from the primary heat exchanger channel and from the device pumping coolant. Such a design can either or both of the main heat exchange channels to carry out the process of evaporation (while in the auxiliary heat exchange channel condensation process), or in both the main heat exchange channels to carry out the process of condensation, either in the same primary heat exchange channel to carry out the process of evaporation, and in another - condensation process. The last and presented on Fig.7; in this case, the object 57 is heated, and the object 58 is cooled. Perhaps a simple change of direction of the current in thermoelectric modules to switch modes, for example, to switch to the operation mode, when the main heat exchange channel 2 line 55 functions as a steam generator, and the main heat-exchange channel 2 line 56 as a capacitor. The device works best if between the capillary walls of channels of pumping various lines installed capillary bridge, representing capillary the th structure. Presented at Fig the design meets this requirement. Here two channels of pumping is performed in the same housing 59, capillary containing the insert 60. Thus one part 61 capillary insert capillary is the partition line 55, and the other part 62 - capillary wall line 56. The Central portion 63 performs the functions of the capillary bridge. In this embodiment, the design of both supply channel is also performed in the same housing 64 containing capillary insert 65. Thus one part 66 of the capillary insert capillary is a partition of the feed line 55, and the other part 67 - capillary wall line 56. The Central part 68 performs the functions of the capillary bridge.

Device for pumping fluid may be in the form of (Fig.9) connected in series additional heat exchange channel 69 and channel pump 16 with the capillary wall 17 overlying the channel, and the additional heat exchange channel is located between the main heat exchange channel 2 and channel throughput, and the device is equipped with a thermal device 18 which has a capability to perform at least one of the two modes. The first mode of operation consists in the removal of heat from facing the additional heat exchange channel surface 19 of the capillary walls and/or from the layer 20 is apillary partitions, adjacent to this surface, and applying heat to the facing the auxiliary heat exchange channel surface 21 of the capillary walls and/or to the layer 22 of the capillary walls adjacent to this surface, and the second mode of operation is the removal of heat from facing the auxiliary heat exchange channel surface 21 of the capillary walls and/or layer 22 of the capillary walls adjacent to this surface, and applying heat to the converted to additional heat exchange channel surface 19 of the capillary walls and/or to the layer 20 of the capillary walls adjacent to this surface. The heat device can also be made with the possibility to carry out simultaneously on both surfaces 19 and 21 of the capillary walls facing the additional and auxiliary heat exchange channels, and/or in layers 20 and 22 adjacent to these surfaces, the processes of heat addition or rejection. When the operation of thermal device in the first mode, the exhaust steam or vapor medium from the primary heat exchange channel is due to the implementation of the condensation process on the additional heat exchange channel. Additional heat exchange channel the condensate is diverted into the channel of pumping and is transferred through the capillary wall. Due to supply t the PLA vaporization occurs recourse to auxiliary heat exchange channel surface 21 of the capillary walls or layer 22 of the capillary walls, adjacent to this surface. Due to capillary forces created by the meniscus formed by the pumping of fluid into a region of higher pressure. The steam produced is transferred into the auxiliary heat exchanger channel. Here is condensation, the heat transfer medium and then transferred through the feed channel and is fed to the main heat exchange channel. Additional heat exchange channel may be connected in thermal contact with a cooling element (Fig.9 not shown), for example, with a cooling element (evaporator) to compressor refrigeration system.

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.
