It has particular, although not exclusive, application to fluid heating and storage tanks having an interior-installed heat exchanger or double walls. It also has particular, although not exclusive, application to heat driven and self-circulating fluid heating and storage systems using the tanks and having multiple energy sources, such as solar heat collectors; and also to those systems of the liquid close-loop automatic type employing modified self powered pumps.. BACKGROUND At present the solar beat application is becoming more and more popular. To reduce the hardware, software, installation, operation and maintenance costs, a self-powered pump and a heat driven liquid automatic circulating system have been disclosed in patent applications No. CA2628605 and PCT 2009000531. In another patent application CA2678584, several liquid heat driven and self-circulating systems are disclosed. All these systems need a basic fluid heating and storage tank. 'Ihe tanks described in the above-mentioned patent applications are different in construction from previous systems, where these previous systems are not convenient for manufacture and installation, and operate well. However, the concept used in the above mentioned patent applications can be expanded into more general applications. This means that the concept of the above pending patent can be used not only for transferring the heat from a higher place to a lower place, but also to transfer the heat to the place at the same level or to a higher place. Accordingly, it is desirable to develop tanks for the heat driven self-circulating solar heating and storage systems by standardized and modularized manufacture. The solar energy varies in different seasons, locations and weather. Thus the solar energy in the solar heat collected in a solar heating system is not steady. It is expected by solar energy customers that a fluid heating and storage tank can be used not only for solar energy, but also for other energy sources. Mucb effort has been made to integrate the solar beating system with building in the last few decades. The liquid heat driven self-circulating technology has made the integration of tie solar heating system with the buildings much easier. It is the third purpose of this invention to make the solar heating systems an integral structural part of the module units of the building.
The fluid heating and storage tanks with an interior-installed heat exchanger or with double walls are known. However existing tanks cannot be used for heat driven and self-circulation fluid heating and storage systems when the tank is not located higher than the heater. The existing tanks for multi-energy sources also cannot be used in a heat driven and self-circulation system. The vaporizing and escaping of the heating liquid is a risk for the continued safe operation of a heat driven and self-circulation liquid heating and storage system. Some solutions for such problems have been developed in the above-mentioned patent applications. This disclosure provides an improved and more efficient liquid vapor condensing and reclaiming apparatus.

DETAILED DESCRIPTION In the first mode of the invention, the fluid heating and storage tank 10 in Fig.A-A is a water tank. It has an interor container 111 comprising sidewall 112, a top cap 113, a bottom cap1 14 to form an enclosed space 110 for a first fluid, which is water. The tank has a cold water inlet 131 and a hot water outlet 132, a release valve 133 at the top (it may at the sidewall too), a drain valvc 135 ard one electric power heater 136. Of cause two electric power heaters can be provided if it is necessary. 24 A columi-shaped (or other shaped) second layer wall 115 is a-ranged outside of the interior container I i , Its top cap (here is a ring) 117 is mounted at the sidewall of the tank and its botom 118 is under the bottom edge 116 of the interior container. Such that the container 119 or second space is enclosed by the bottom cap and sidewall 112 of the interior container, outer wall 115, ring 117 and bottom cap 118. The second container is for the second fluid, which is a liquid e.g. water or ethylene glycol etc. At the second wall the inlets 121 and 123, outlets 122 and 124 are arranged for a secondary fluid. The outlet 122 and 124 arc Tiot higher than the outlet 121 and 123 to sure the self-circulating of the heated liquid. At the bottom cap of second wall there are may some struts 128 and 129 are provide to support the interior container for the second wall. The heat of the container 119 is transferred to the fluid in the interior container I 1[ through the sidewall 112 and the bottom cap1 14. So that the material of the interior-container needs to be a heat conductive material e.g. copper, aluminum, stainless steel or steel plated glass or porcelain enamel. A breathing channel extends upwardly from the top port 125 and it is connected to the breathing fitting 126 at the top of the tank. A second fluid condensing and reclaim apparatus 51 is connected at the fitting 126. Fig.3 is a schematic diagram illustrating the apparatus 51. The apparatus 51 is an airtight container. It has a top 511 and a bottom 512 and sidewall 513. An inlet pipe 52 having its one end extending upwardly from the bottom into the container and is mounted to the bottom of the container. In Fig. 3, the inlet pipe 52 is a hollow bolt. Its opposite end 522 can be revolved directly into the breathing filing at the top of lhe tank. A flexural U-shaped pipe 53 (it may be many other shape pipes, e.g. W-shapod etc.) extends its one end 531 from the sidewall of the container 51 into the container and under the tope wall 511. Its upper end is spaced from the top wall. The other parts including its lower part of the pipe are located outside of the tank. The pipe extent its opposite end downwardly first and then upwardly. So that the opposite end of pipe 53 is facing upwardly and its lower part 533 is located near to the bottom of the container. Referring to Fig. 4, an alternative fluid vapor condensing and reclaiming apparatus is illustrated. Except U shaped tube 63, other parts of this second embodiment are similar to apparatus 51 described above. The 25 reference numerals in this drawing are changed from the first digital 5 to 6. Otherwise the construction is similar to apparatus 51 described above. A U-shaped tube 63 extends upwardly its one end 634 from- the bottom 612 of the container 61 into the container and under the top wall 611. There is a gap betwcon the end and the top wall. In Figure 6, the apparatus provides the breathing for ie liquid due to expansion and contraction. A small amount of condensed liquid is retained at the bottom part of the apparatus 61, which prevents further vapor from escaping into the atmosphere through the U-shaped tube 63. Fig.4 is a schematic diagram illustrating another kind of apparatus for liquid vapor condensing and reclaiming. The feature of above mentioned container is to condense the liquid vapor in the container and let the condensed liquid returns to the heater. Usually any inside wall of a container at the temperature less than 100 degree can make the vapor condensing. Usually any metal, e.g. plastic, glass or polymeric material, can be used for making the container, Whien the system and environment temperature is high, in order to speed up the condensing processing, some condensing pieces may be installed in the container (did not shown in the Fig. 3 and 4). The flexural pipe 63 also needs to make the vapor condense in the tube. Furthermore, at the U shaped lower part of the pipe a few condensed liquid can be stored temporary to block the escaping of the escaped vapor. Thc flexural pipe can be made of many different materials e-g. glass, metal, plastic, polymeric material etc. The shapes of the pipe are flexible, e.g, U shaped, W shaped or the like in which the bottom part of the pipe can store some condensed liquid. Transparent pipes may be used to provide visible monitoring of the condensed liquid. One of the main concerns for an operating beat driven self-circulating fluid heating and storage tank e.g. solar heating system is the fluid vaporizing and the vapor escaping through the breathing port. It may result a fail of the system operation. Tbc application of the above introduced apparatus for fluid condelising and reclaiming resolves this problem completely. Usually the container of the apparatus are made of transparency materials, e.g. transparent glass, plastic or polymeric materials, thus the liquid level of the heat exchanger can be visually monitored, and the more liquid can be added through the breathing port if it is necessary. When the position of the secondary bottom wall is moved upwardly until it is connecting to the edge of the first bottom wall, the tank becomes a fluid heating and storage tank with double sidewalls. Fig.5 also illustrates the operation situation of a tank with double side walls but without double bottom wall. 26 There are two spare bolt caps for closing the unused inlet and outlet and one spare bolt cap for closing the unused breathing fitting. If necessary, all the breathing ports can be closed. In this case, the tank can be used as a regular tank with heat exchanger or used with self-power pump or ciccuric pump. Fig.2 is schematic diagram illustrating the fluid heating and storage tank with double bottom. walls, which is a columned water tank 20. The columned sidewall 201, coronary top cap 202 and bottorn cap 203 form a closed space 21 for primary fluid, which can be water. The sidewall 201 extends from the bottom edge 206 and forns a new extended sidewall 204. The sidewall 204 together with the first bottom wal 203 and the second bottom wall 205 enclose a second space 22 for the secondary fluid which can be water or a antifreeze e.g. glycol etc. On the sidewall 201 of the tank, there are two pipes 208 and 209 arranged in 180* relative to one another. Their lower ends 221 and 222 extended respectively through the sidewall and into the second space 22. The other ends 223 and 224 extended upwardly around te sidewall and are connected to a three- way pipe joint. The upper end of the three-way pipe extends to the top of the tank. The third port of the three- -way pipe is for connecting to the beater of secondary fluid. 'The two tubes 208 and 209 may be other kinds of channels. For example they tray be two slots to cling at the surface of the sidewall. One end of these tubes extends into the second space and the opposite end extends to the top of the tank. For the rust protection purpose, the inside of the channels riced to plat glass or porcelain enameL Alternatively, the tubes or channels may be arranged inside of the tanks. The ends of the pipes or channels also may be located at some locations under the top of the tank. The angle of the two pipes 208 and 209 on the sidewall of the tank may also be located at 90 degrees or other selected angles. At the sidewall near the bottom, the outlets 212 and 214 of the secondary fluid are arranged. Fig. 5 also shows that the second space of the tank is separated into two left and right sub-spaces by a clapboard 207. The liquids in these two sob-spaces are isolated. There are two separated sub-liquid systems in the second space. This kind of the system is used for two kinds of heaters in the two sides of the tank, Especially it is used for the system wherein one heater requires the forced circulating. For example, first heater is a solar heater and second heater is another energy heater which needs a forced circulating, e.g. earth energy or air energy, For using some r COrgy source, e.g. biomes energy, gas energy and fossil fuel energy, if there is no need of a forced circulation, the secondary liquid system may either separated or not separated. Correspondingly the breathing ports 223 and 224 can be connected to the atmosphere by two ports or either one (e.g. 224) of two ports, when the other port is closed by a spare cap. When the two heaters connected to the tank are both solar heal collector, the clapboard in the second space of water tank may not necessary. Theu the top ends of two pipes are opened. 27 Tt can be understood by those skilled in de art that many common elements, fur example, release valve, drain valve, protective anode and one or two electric heater(s) etc may also provided in the tank. Further more, a heat insulation layer and a crust outside of the tank wall may be provided. All of these elements are shown in Fig. 1. Please refer to Figure 1. Fig.6 is a schematic diagr-am illustrating the heat driven and sel -circulation fluid heating and storage system employing a fluid heating and storage tank with double sidewalls and double bottom walls and two solar heat collectors. Even both solar heat collectors in Fig.6 are plate solar heat collectors. But each of them can be any kind of the solar heat collector, for example, the plate solar heat collector (with or without the heat tube), Vacuumed tube solar heat collector (with or without the beat Lube) and U-shaped solar heat collector etc. The solar heat collector 760 in Fig.6 has a secondary fluid inlet 7611 and outlet 7612. The first conduit 762 is connected its one end to inlet 422 of the tank and an opposite end to the outlet 7611 of the solar beat collector 761. The one end of second conduit 763 is connected to the outlet of the tank and the opposite end 7632 to the inlet of solarheat collector 760, The second solar heat collector 780 has similar connection arrangement. Based on thc application requirement, two couple inlet and outlet, 721/722 and 723/724 may be arranged at the sidewall in any angle from 90-180 degree. When the heat driven self-circulated liquid heating system is used as building elements, for example as a unit clement of the roof fence, veranda etc, the unibs with tWo solar heat collectors arranged in 180 degree ate the plane unit of building walls, fences and verandas. The units with two solar heat collectors a-anged in 90 degree are the corner units. As a building component unit, the heat driven and self-circulating solar beating and storage system should be and can be a compacted component. In Fig. 6, when the solar heat collectors are moved close to the fluid beating and storage tank and make the solar heat collector's sizes larger, a compacted solar heating and storage system will be find. Similar to those shown in Fig. 5, each of the two couple of inlet/outlet ports is in a plumb line. However, the angle of the solar heat collector may be oriented to an obliquity (i.e. not 90 degree) angle to the surface of the earth. Even if the inlet and oat ports are in a plumb line, we still can adjst. tlie arrangement of connecting conduits 762, 763,782and 783 to lct the solar beat collector to be at an obliquity angle (not 90 28 degree) to the surface of the earth for receiving a point-black amount ofrsun light. It is also possible to arrange the entire unit of the solar heat collector and the tank to stay at an oblique angle to the earth. In this case the tank is catty-cornered. To protcl the fall, the support of the system needs a special design. After installation, the heat driven self-circulating solar heating and storage system 90 comes into being two fluidly separated but heat connected liquid spaces. The first space is the interior container of tank 70 which may be filled with the liquid to be heated e.g. water, air or other fluids. Ihe second space is formed by the interlayer 719, two conflux tubes of the two solar heat collectors, connecting conduits and the inner space of the apparatus for fluid condensing and reclaiming 51. This close-loop system connects to the atmosphere indirectly through the U shaped tube 63. After the system is installed, the system will be filled with the heat conductive liquid, e,g. water or glycol. The liquid level in the tank will be lower than the breathing fitting. When the sunlight iTadiation heats the liquid in the solar heat collectors 760 and 780, the liquid ii the conflux tubes 761 ard 781 (within the heat insulation which is nol shown in the Figure) is heated and teicd to flow upwardly. The heated liquid flows through the connecting conduit 762 into the interlayer 719, and the heated liquid transfers its beat to the liquid in the tank through the sidewall and bottom wall of the interior container. Then the liquid temperature drops and the volaue of the liquid also drops too. Through the outlet 724 and the conduit pipe 763, the cooled liquid flows back into solar heat collector 760 again for being heated. This processing continues in circles to heat the water in the tank by the solar heater. i this process, the solar heat is the only energy source to ddive the circulating liquid and to complete the energy exchange, Therefore, no other energy source, e-g. electric power, is required except the solar heat. In this process, when the sunlight is stronger, the heat circulation will be faster, whereas the heat circulating is slower, when the sunlight is weaker. When there is no sunlight, the heat circulating will terminate completely. It is not necessary to provide additional controller for controlling the liquid circulation. 'This head driven system has the functions of self-driven, self-control and self-circulating. When the system is in operation, the breathing port 725 serves several important functions. First it releases the pressure in the system. caused by the heated liquid expansion for keeping the systern pressure closes to the atmospheric pressure. It also provides a space for the liquid's breathing (namely, expansion and contraction) so as to facilitate the self -circulating operation. When the heater is in operation, the heated liquid causes some liquid and vapor to flow into the container 51. The part of the vapor is cooled and condensed in the container 51, and then is returned to the heat exchanger, Some vapor may escape into the U-Shaped tube and then change into liquid, which will stay in the lower part of the tube. The gathered 29 liquid in the tube blocks the further escape of vapor and would enhance further vapor to condense in the tube. When the heater stops working, the liquid in the container 51 and interlayer 719 cools down and contracts, so that the system generates a negative pressure to reclaim all the li quid gathered in the U-shaped tube to be drawn back into the heat exchanger. Even though the space storing the heat liquid is connected to the atmosphere directly or indirectly, lie system working temperature is high, but the loss of the secondary liquid through vaporizing is not significant. Accordingly the system operates continuously and safely. For the space or other reasons, sometimes the solar heating system maybe equipped with single solar heat collector only. In this case, the solar heat collector 780 may be removed and the spare inlet and outlet ports 421 and 423 are closed as shown in Fig.5. In another alternative, we can also replace the single solar heat collector by another type of heater operated with another energy source. Based on the above-mentioned description, the tank in Fig.5 and Fig. 6 can be replaced by a tank with double layers of sidewalls or double layers of botom walls. Fig. 7 illustrates a heat driven self-circulating liquid heating and storage system 11 using a tank 10 witli double layer sidewalls and bottom walls. Comparing to Fig. 5, a solar hear collector 760 and a other energy source heater. The system illustrated shows a nature gas heater. The tank 10, solar heat collector 760 and the connections between it and the tank are the same as shown in Fig.6. Here the nature gas heater 1100 is a central vacant cylinder (or other shaped e.g. taper, square etc) metal (or ceramic ec) tank. There is a second liquid inlet 1106 provided at the bottom wall and a conduit connects the inlet with an outlet 124. At the upper (or top) sidewall there is a secondary fluid outlet 1105, which is connected to an inlet 123 of the tank through conduit 1107. A valve 1109 mounted in series to the tube 1107 is operative for turning off the gas supply when the heater is out of service. A similar valve may also be connected to the bottom conduit for the samepuirpose. The cover 1 113 is for sheltering from the spark occurring in the heater. The gas heater 1100 has a outer wall 110 1 and a interior 1102 and heat insulation 1103 (not show in the figure). The secondary fluid is stored iu the space enclosed by interior and outer walls, top and bottoms caps. The interior chamber 1104 has a gas burner I 1 10 which is supplied the gas by gas pipe I I l1. There is a control valve 1112 for adjusting the gas supply. When the system is in operation, the nature gas burns in the chamber 1104 of the heater to heat the inside wall 1102, thus the liquid, of the heater 1100 (there may be protective coat for heat insulation and corrosion 30 protection). The heated liquid passes through the outlet 1105 and conduit 1107 to reach in the interlayer 119 of the tank. After the secondary liquid has transfe-ed the heat to the water in the tank., the secondary liquid returns to the heater 1100 through the outlet of the taik. This processing is similar to the solar heat collector. For a heat driven sel f-circulating fluid heating and storage system with a solar heat collector and another heater having another energy source, its operation is similar to that mentioned in the system with two solar heat collectors. Even though the second heater shown in Gig. 7 is a nature gas beater, it can also be any alternative kind of non-solar heaters, e.g. fossil fuel (e.g. coal) heater, biomass energy heater, (including biomass gasification heater), nature gas, earth energy and air energy heater. The differences of this kind of the liquid heater is that the beating liquid storage space of this kind of heater is much smaller than any other kind of liquid heater. For example, one metal tube can be the storage coTItainer of the liquid to be heated in the heater. For the reason such as heat insulation and corrosion protection e.g. a firebrick or a ceramic protetive layer may be provided, Purefler more, this heater can be a heater of earth or air beat energy. Because these kinds of the heaters usually need the forced circulation, so th beaters need a separator (e.g. separator 207 in Fig.2) to separate the liquid into two sub-systems. In this case, only the sub-system connected to th1e solar heat collector has a breathing port. Another sub-system either has no breathing port or the port is closed with a spare cap. Fig. 8 illustrates the heat driven self-circulating fluid heating and storage system 130 with a heat appliance (here is a radiator). The system includes a solar heater 760, a radiator and a liquid heating and stowage tank 10 with double sidewalls and double bottom walls. In Fig. 8, the tank 10 and radiator and their connections are same as the embodiment shown in Fig.7. The radiator includes a fin pipe 771 ( it also can be a coil tube, helix tube, straight tube or a flat heat exchanger etc). Two pipes connect inlet 773 and outlet 774 of the radiator to the inlet 123 and the outlet 124 of the tank respectively. Two valves 777 and 778 are for separating the ra diator with the tank when necessary. Solar heat collector 760 receives solar cenrgy and transfers it to the tank 10, so the temperature in the tank is higher than the temperature of the surrounding air. When heated air is required, the valve 777 and 778 of the tank a-re opened, so that the hot water circulates into valve 777 and go through fin tube 771 to emit warm air there from. After the emission of warm air, the cold water then goes through valve 778 to returns to the bottom of the tank 10. In order to increase the amount of heated air generating and to send the air to a planned direction, a cover 772 with an active window 770 rulay be provided. (as shown in the figure 8, the window is opened upwardly. The cover 772 has an inlet 779 for the air to be heated. In fact the direction of 31 the window can be varied. One or more fans may be provided in the cover to speed up Lie heat pervasion from the fin tubc. ( the fans did not show in the figure). If a canal is added to the window of cover 772, the heated air can be transferred to a desire location ( the canal did not show in the figure). it can be note that the fitting [123 of the tank is an inlet when it is connccted to a heater, but when it is connected to a radiator, it becomes an outlet, while the fitting 124 is an outlet when it is connected to a heater, but it becomes an inlet when it is connected to a radiator,. It is also possible to install the radiator or other heat appliances in a heat driven and self-circulating system with two solar heat collectors or with one solar hear and one other heat source. In this ease, the fluid heating and storage tank need three couple inlets and outlets. In the second mode of the invention, Fig. 1-B illustrates a fluid heating and storage tank, which is a hot water tank 30. The tank has a container 301 for storing water. There is an inlet 313 for cold water and an outlet 312 for hot water. On the top wall, there is a protective anode 319 and a release valve 314. At the side wall there is a drain valve 316 and electric heater 315. Outside of the container there are the heat insulation 317 and a crust 318. At the wall 301 of the tank 30, there are two inlet fittings 321 and 322 and two outlet fittings 323 and 324 are also arranged. Further there is a breathing port 325 at the top of the tank. A heat exchanger 330 is disposed within the fluid heating and storage tank 30 for flowing secondary fluid, which is a liquid through the storage tank in isolation from the water, The heat exchanger has first inlet 3210, first outlet 3230, second inlet 3220 and second outlet 3240 for secondary fluid and at least one breathing port 3250. Each port of inlets, outlets and breathing ports are mounted on one of the corresponding connecting fitting, i.e. 321/3210, 322/3220,323/3230/324/3240 and 325/3250 respectively. The two secondary fluid inlets 321 and 322 are located higher than the two outlets 323 and 324.The breathing fitting is located not lower than said inlet fittings. The heat exchanger 330 is combined with a coil tube 3301 and sonic straight tubes. The coil tube can be a fin tube, a helix tube, or a straight tube. The heat exchanger also can be a flat plate heat exchanger having square shape or ellipse shape, etc. The key point is that two inlets 3210 and 3220 connect (or mounted) to the corresponding inlet fitting 321 and 322 respectively, other two outlets 3230 and 3240 connect (or mounted) to the corresponding outlet fittings 323 and 324. One breathing port 3250 connects (mounts) to the corresponding breathing fitting 325. The ports 321FE322032303240325 are liquidly conimunicated. The inlets 321 and 322 arc not lower than outlets 323 and 324 to ensure the self-circulating of the heated liquid. A second fluid condensing and reclaiming apparatus 51 is connected at the fitting 325. Fig.3 is a schematic diagram illustrating the apparatus 51. 32 The apparatus 51 is an airtight container. It has a top 511 and a bottom 512 and sidewall 513. An inlet pipe 52 having its one end extending upwardly from the bottom into the container and is mounted to the bottom 521 of the container. In Fig. 3, the inlet pipe 52 is a hollow bolt. Its opposite end 522 can be revolved directly into the breathing fitting at the top of the tank, A flexural U-shaped pipe 53 (it may be pipe of other shapes, e-g. W-s-haped etc.) extends its one end 531 from the sidewall of the container 51 into the container and under the tope wall 511. Its upper end is spaced from the top wall. The other parts including its lower part of the pipe are located outside of the tank. The pipe extends its opposite end downwardly first and then upwardly, so that the opposite end of pipe 53 is facing upwardly and its lower part 533 is located near the bottom of the container, Referring to Fig. 4, an alternative fluid vapor condensing and reclaiming apparatus is illustrated. Not including U-shaped tube 63, other parts of this second embodiment are similar to apparatus 51 described above. The reference numbers in this drawing have been changed the first digital from 5 to 6. Otherwise the construction is similar to apparatus 51 described above. A U-shaped tube 63 extends upwardly having one end 634 from the bottom 612 of the container 61 into the container and under the top wall 611. There is a gap between the end and the top wall. In Figure 6, the apparatus provides the breathing for the liquid due to expansion and contraction. A small amount of condensed liquid is retained at the bottom part of the apparatus 61, which prevents further vapor from escaping into the atmosphere through the U-shaped tube 63. The feature of the above mentioned container is to condense the liquid vapor in the container and let the condensed liquid return to the heater. Usually any inside wall of a container at a temperatures of less than 100 degrees Celsius can make the vapor condensing. Usually any metal, e.g. plastic, glass or polymeric material, can be used for maldng the container. When the system and environment temperature is high, in order to speed up the condensing processing, some condensing pieces may be installed in the container (not shown in Fig.3 and 4). The flexural pipe 63 also needs to make the vapor condense in the tube. Furthermore, at the U shaped lower part of the pipe the condensed liquid can be stored temporary to block the escaping of the escaped vapor. The flexural pipe can be made of many different materials e.g. glass, metal, plastic, polymeric material etc. The shapes of the pipe are flexible, e.g, U shaped, W shaped or the like in which the bottom part of the pipe can store some condensed liquid. Transparent pipes may be used to provide visible monitoring of the condensed liquid. One of the main concerns for an operating heat driven self-circulating fluid heating and storage tank e.g. solar heating system is the fluid vaporizing and the vapor escaping through the breathing port. It may result in a failure of system operation. The application of the above introduced apparatus for fluid condensing and reclaiming resolves this problem completely. Usually the container of the apparatus is made of transparency materials, e.g. transparent glass, plastic or polymeric materials, thus the liquid level of the heat exchanger can be visually monitored, and the more liquid can be added through the breathing port if necessary. 33 There are two spare bolt caps for closing the unused inlet and outlet and one spare bolt cap for closing the unused breathing fitting. If necessary, all the breathing ports can be closed. In this case, the tank can be used as a regular tank with a heat exchanger or used with a self-power pump or electric pump. Fig.2-B illustrates another kind of fluid heating and storage tank, which is a hot water tank 40, as in Fig. l-B. The fluid heating and storage tank 40 in Fig. 1-B is a water tank. It has a water container 401 comprising a cold water inlet 413 and a hot water outlet 412. At the top of the tank, there is a release valve 414 (it may at the sidewall too), a drain valve 416 and one electric power heater 415. Of course two electric power heaters can be added if necessary. The tank further includes the heat insulation layer 417 and a crust 418. On the sidewall 401 of the tank two inlets 421 and 422, two outlets 423 and 424 and a breathing fitting 425 are arranged. Fig 2-B lists different components of the tank in details. They are not all necessary for the basic operation. For example, the crust may or may not be needed, if the heat insulation is ceramic. The number of the electric heater may be one, two or zero. The release valve can be installed on the top or sidewall of the tank. A heat exchanger 430 is disposed within the fluid heating and storage tank 40 for flowing secondary fluid, which is a liquid through the storage tank in isolation fi-om the water. Said heat exchanger has a first inlet, a first outlet, a second inlet and a second outlet for secondary fluid and at least one breathing port. Each of the ports (inlet, outlet and breathing ports) are mounted on one of relative to connective fittings, i.e. the first inlet fitting, the first outlet fitting, the second inlet fitting and the second outlet fitting and at least one breathing fitting to connect to said storage tank. The said two secondary fluid inlets are not lower than the two said outlets; and said breathing fitting is not lower than said inlet fittings. Comparing to Fig. 1-B, the heat exchanger in Fig.2 can be separated into to liquidly isolating sub-system 4310 and 4l320 by an isolation structure. This structure is a removable isolation plug 4309 located between tubes 4306 and 4307 and a second isolation plug 4308 located between tubes 4303 and 4304. The diameters at these two places are a little smaller than the diameters of the tubes. The two plugs are inserted through the ports 421 and 423. The plugs may also the pre-welded isolation caps. Here the sub-system 4310 is formed by across tubes 4303, 4306 and fin tube 4301. The sub-system 4302 is formed by across tubes 4304, 4307 fin tube 4302 and breathing pipe 4305. A second fluid condensing and reclaiming apparatus 51 is connected at the fitting 126. Fig.3 is schematic diagram illustrating the apparatus 51 The apparatus 51 is an airtight container. It has a top 511 and a bottom 512 and sidewall 513. An inlct pipe 52 has one end which extends upwardly from the bottom into the container and mounts on the bottom of the container. In Fig. 3, the inlet pipe 52 is a hollow bolt. Its opposite end 522 can be revolved directly into the breathing fitting at the top of the tank. A flexural U-shaped pipe 53 (it may be in many other shape pipes, e.g. W-shaped etc.) extends its one end 531 from the sidewall of the container 51 into the container and under the tope wall 511. There is a gap 34 between the end and the top wall. The other parts including its lower part of the pipe stay outside of the taul. The pipe extends its opposite end downwardly first and then upwardly. So that the opposite end of pipe 53 is facing upwardly and its lower part 533 is near to the bottom of the container. Refen-ing to Fig. 4, an alternative fluid vapor condensing and reclaiming apparatus is illustrated. Except T shaped tube 63, other parts in Fig 4 are the same as in Fig.3. Each part's number differs by the first digital from 5 to 6, having all the names of the parts in Fig 4. identical to that in Fig.3. An U-shaped tube 63 extends upwardly its one end 634 from the bottom 612 of the container 61 into the container and under the tope wall 611. There is a gap between the end and the top wall. The feature of above mentioned container is to condense the liquid vapor in the container and let the condensed liquid return to the heater. Usually any inside wall of a container at the temperature less than 100 degrees Celsius can make the vapor condensing. Usually any metal, plastic, glass or polymeric material can be used for the container material. When the system and environment temperature is high, to speed up the condensing processing, some condensing pieces may be installed in the container (not shown in the Figures). The flexural pipe 63 also needs to make the vapor condense in the pipe. Furthermore at the lower part 633 of the pipe 63 condensed liquid can be stored temporarily to block the escaping of the escaped vapor. The flexural pipe can be made of many different materials e-g. glass, metal, plastic, polymeric material etc. The shapes of the pipe are flexible, e.g. U shaped, W shaped or others, when the bottom part of the pipe is used to store some condensed liquid. Of course the transparent pipes are preferred. Fig.6-B is a schematic diagram illustrating the heat driven and self-circulated fluid heating and storage system employing a fluid heating and storage tank 40 with interior installed heat exchanger 430 and two solar heat collectors. Even both solar heat collectors in Fig.6 are plate solar heat collectors. Each of them can be any kind of the solar heal: collector, for example, the plate solar heat collector (with or without the heat tube), Vacuumed tube solar heat collector (with or without the heat tube) and U-shaped solar heat collector etc. The solar heat collector 760 in Fig.6-B has a secondary fluid inlet 7611 and outlet 7612. The first conduit 762 is connected its one end to inlet 422 of the tank and an opposite end to the outlet 7611 of the solar heat collector 761. The one end of second conduit 763 is connected to the outlet of the tank and the opposite end 7632 to the inlet of solar heat collector 760. The solar heat collector 780 has similar connection arrangement, Based on the application requirements, two couple inlet and outlet, 721/722 and 723/724 may be arranged at the sidewall in any angle from 90-180 degrees. When the heat driven self-circulated liquid heating system is used as building elements, for example as a unit element of the roof, fence, veranda etc, the units with two solar heat collectors arranged in 180 degrees are the plane unit of building walls, fences and verandas. The units with two solar heat collectors arranged at 90 degrees are the corner units. 35 As a building component unit, the heat driven self-circulated solar heating and storage system needs to be and can be a compacted component. In Fig. 6-B, when the solar heat collectors 780 and 760 arc moved close to the fluid heating and storage tank while making the solar heat collector larger, a compacted solar beating and storage system can be made. Similar to those shown in Fig. 5-B, each of the two couple of inlct/outlet ports is in a plumb line. However, the angle of the solar heat collector may be oriented to an obliquity (i.e. not 90 degrees) angle to the surface of the earth. Even if the inlet and outlet ports are in a plumb line, we still can adjust the arrangement of connecting conduits 762, 763,782and 783 to let the solar heat collector to be at an obliquity angle (not 90 degrees) to the surface of the earth for receiving a point-black amount of sun light, It is also possible to arrange the entire unit of the solar heat collector and the tank to stay at an oblique angle to the earth. In this case the tank is catty-cornered. To protect the tank from falling, the support of the system needs a special design. After installation, the heat driven self-circulating solar heating and storage system 100 becomes two fluidly separated but heat connected liquid spaces. The first space is the interior space within tank 40 which may be filled with the liquid to be heated e.g. water, air or other fluids. The second space is the space formed by the heat exchanger 430, two conflux tubes 761 and 781. of the two solar heat collectors 760, 780, connecting conduits 762 763, 782, 783 and the inner space of the apparatus for fluid condensing and reclaiming 61. (the stoppers 4307 and 4308 are removed). This close-loop system connects to the atmosphere indirectly through the U-shaped tube 63. After the system is installed, the system will be filled with the heat conductive liquid, e-g. water or glycol etc. The liquid level in the tank will be lower than the breathing fitting. When the sunlight irradiation heats the liquid in the solar heat collectors 760 and 780, the liquid in the conflux tubes 761 and 781 (within the heat insulation which is not shown in the Figure) is heated and tends to flow upwardly. The heated liquid flows through the connecting conduit 762 and 782 into the heat exchanger 430, and the heated liquid transfers its beat to the liquid in the lank. Then the liquid temperature drops and the volume of the liquid also drops too. Through the outlet 424 and the conduit pipe 763, the cooled liquid flows back into solar heat collector 760 again for being heated. This processing continues in circles to heat the water in the tank by the solar heater. In this process, the solar heat is the only energy source to drive the circulating liquid and to complete the energy exchange. Therefore, no other energy source, e.g. electric power, is required except the solar heat. In this process, when the sunlight is stronger, the heat circulation will be faster, whereas the heat circulating is slower, when the sunlight is weaker, When there is no sunlight, the heat circulating will terminate completely. It is not necessary to provide additional controller for controlling the liquid circulation. This head driven system has the functions of self-driven, self-control and self-circulating. 36 When the system is in operation, the breathing port 425 serves several important functions. First it releases the pressure in the system caused by the heated liquid expansion for keeping the system pressure closes to the atmospheric pressure. It also provides a space for the liquid's breathing (namely, expansion and contraction) so as to facilitate the self -circulating operation. When the heater is in operation, the heated liquid causes some liquid and vapor to flow into the container 51. The part of the vapor is cooled and condensed in the container 51, and then is returned to the heat exchanger. Some vapor may escape into the U-Shaped tube and then change into liquid, which will stay in the lower part of the tube. The gathered liquid in the tube blocks the further escape of vapor and would enhance further vapor to condense in the tube. When the heater stops working, the liquid in the container 51 and the heat exchanger cools down and contracts, so that the system generates a negative pressure to reclaim all the liquid gathered in the U-shaped tube to be drawn back into the heat exchanger. Even though the space storing the heat liquid is connected to the atmosphere directly or indirectly, the system working temperature is high, but the loss of the secondary liquid through vaporizing is not significant. Accordingly the system operates continuously and safely. For the space or other reasons, sometimes the solar heating system may be equipped with single solar heat collector only. In this case, the solar heat collector 780 may be removed and the spare inlet and outlet ports 421 and 423 are closed as shown in Fig.5. In another alternative, we can also replace the single solar heat collector by another type of heater operated with another energy source. Fig. 7 illustrates a heat driven self-circulating liquid heating and storage system 11 using a tank 40 with a interior installed heat exchanger. Comparing to Fig. 6, in Fig.7, a solar heat collector 760 is replaced by some other energy source heater. The system illustrated shows a coal water heater. Fig. 7 illustrates a heat driven self-circulating liquid heating and storage system 120 using a tank 40 with an interior installed heat exchanger. Comparing to Fig. 6, a solar heat collector 760 and some other energy source heater. The figure shows that it is a fossil fuel heater 1200. In Fig. 7, the tank 40, solar heat collector 760 and the connections between them are similar to those mentioned in Fig.6. Here the coal heater 1200 comprises a central vacant cylinder (or other shaped c.g. taper, square etc) metal (or ceramic etc) tank 1201. The tank 1201 further comprises an inner wall 1202 and an outer wall 1204. One metal coil tube 1203 located in the heat insulation material. One end of the tube is at the bottom of the tank 1201. The opposite end of the tube is at the upper part1205 of the tank. The bottom of the heater is a hearth for coal burning in side. When the system is in operation, the coal burns in the hearth 1210 to heat the water tube 1203. The water in the tube is heated and expended to move upwardly to the heat exchanger 430 through tubc1207. In the heat exchanger the water give up the heat and returns to the tube 1203, through outlet 424 and tube 1206, for heating again. The above mentioned processing is continued in cycle, the water in tie tank will be heated. The processing in this heater system is similar with the processing of the solar heat collector system. A valve 1109 series connected to the tube 1207 for turn off 37 the connection with heater when the heater is out of service. The same valve may be connected to the bottom conduit 1208 for same reason. For a beat driven self-circulating fuid heating and storage system with a solar heat collector and an another energy source, its other parts have similar working processing that mentioned in the prior system having two solar heat collectors. Even though the second heater shown in Fig. 7 is a coal heater, it can also be any alternative kind of non solar heaters, c.g. fossil fuel (e.g. coal) heater, nature gas heater, biomass energy heater, (including biomass gasification heater), earth energy and air energy heater etc. The difference of this kind of the liquid heater is that the heating liquid storage space of this kind of heater is much smaller than any othcr kind of liquid heater. For example, one metal tube can be the storage container of the liquid to be heated in the heater. For the reason such as heat insulation and corrosion protection e.g. a firebrick or a ceramic protective layer may be provided. Further more, this heater can be a heater of earth or air heat energy. Since these kinds of heaters usually require forced circulation, so the heaters need a separator (e.g. separators 4308 and 4309 in Fig.2) to separate the liquid into two sub-systems. In this case, only the sub-system connected to the solar heat collector has a breathing port. Another sub-system either has no breathing port or the port is closed with a spare cap. Fig. 8 illustrates the hea t driven self-circulating fluid heating and storage system 140 with a heat appliance (radiator 970). The system includes a solar heater 760, a radiator 970 and a liquid heating and storage tank 30 with an interior installed heat exchanger 330. In Fig. 8, the tank 10 and radiator and their connections are same as the embodiment shown in Fig.7. The radiator includes a fin pipe 771, which may alternatively be a coil tube, a helix tube, a straight tube or a flat heat exchanger etc. Two pipes connect inlet 773 and outlet 774 of the radiator to the inlet 123 and the outlet 124 of the tank respectively. Two valves 777 and 778 are for separating the radiator with the tank when necessary. Solar heat collector 760 receives solar energy and transfers it to the tank 30, so the temperature in the tank is higher than the temperature of the surrounding air. When heated air is required, the valve 777 and 778 of the tank are opened, so that the hot water circulates into valve 777 and go through fin tube 771 to emit warm air there from. After the emission of warm air, the cold water then goes through valve 778 to return to the bottom of the tank 30. In order to increase the amount of heated air generating and to send the air to a planned direction, a cover 721 with an active window 770 may be provided. (as sbown in figure 8, the window is opened upwardly). In fact the direction of the window can be varied. One or more fans (not shown in the drawings) may be provided in the cover to speed up the heat pervasion from the fin tube. (If a channel is added to the window of cover 721, the heated air can be transferred to a desire location (not shown in the figure). 38 It can be noted that the fitting 322 of the tank is an inlet when it is connected to a heater, but when it is connected to a radiator, it becomes an outlet, while the fitting 324 is an outlet when it is connected to a heater, it becomes an inlet when it is connected to a radiator. It is also possible to install the radiator or other heat appliances in a heat driven self-circulated system with two solar heat collectors or with one solar heat and one other heat source. In this case, the fluid heating and storage tank need three pairs of the inlets and outlets. In the third mode of the invention, i-efrring to FIG. 1-C, an exemplary heat driven liquid close-loop automotive circulating system is illustrated during use, The system 110 includes a heat collector 111 having a vessel 112 filled filly with beat transfer medium, which is a liquid 113; said vessel having an inlet 115 and an outlet 114; said outlet 114 is not lower than said inlet 115. A self-powcred pump 121 for heated liquid which used with a liquid heat collector I ll The self-powered pump 121 has an airtight container 1210 for containing heated liquid, having a wall to separate its outer and inner spaces. The inner space is filled with heated liquid partially, so that there is a upper air/vapor space 127 above liquid level surface 126 and lower liquid space 125 under liquid level surface 126. An inlet 122 and a outlet [23 arranged on said wall of the container that both are under the liquid level surface 126 in said container, and the inlet 122 is not lower than said outlet 123. A breathing channel 124 mounted on said wall of said container 121 for connecting to atmosphere with said inner upper air/vapor spacel27 above liquid level surface 126; said breathing channel 124 has a liquid vapor condensing and reflux structure that will be explained in Fig.2-C and Fig.3-C. First conduit 131 connects its one end 1311 at the outlet 114 of the heat collector 111. The opposite end of conduit 131 connects at the inlet 122 of the self-powered pump 121. The inlet 122 of self-powered pump 121 is not lower than die outlet 114 of said heat collector 111. This is for the heat driven liquid move upwardly to the self-powered pnup 121. Second conduit [32 connects its one end 1321 at said outlet 123 of said self-powered pump 121 and its opposite end 1322 at said inlet 115 of said heat collectorl21, The outlet 123 of self-powered pump 121 is not lower than the inlet 115 of said heat collectOr 111 Fig. I-C shows that the second conduit 132 has its top potion higher than the beat collector 111 and the lower portion lower than the heat collector Ill and its middle portion is as high as the level of the heat collector .I1l located. in Fig. 1-C, the heat collector 11, conduit 13 1., self-powered pump 121 and conduit 132 are formed a heated liquid close-loop circuit. When the heat collector 111 received the heat, the heated liquid tends to move upwardly and the cooler liquid in the opposite direction. The heated liquid moves to the self-power pump 121 and the cooler liquid in the bottom of heat collector 111 and conduit 132 comes and replenishes the space. So that a circulating power is generated in the system 110 and make the system operation continuously when the heat is available. 39 This example circuit shows Chat by employing a self-powered pump at the upper place of the heat collector, It is possible to form a close loop circuit. In is circuit a heater can transfer its heat to the places whatever is higher, lower or the samte level of the heater without extenal power pump.

The heated liquid, it is water, moves to the storage tank 431 and the cooler liquid in the bottom of heat collector 411 and conduit 452 comes and replenishes the space. So that a circulating power is generated in the system 410 and make the system operate continuously when the heat is available. i- some ease, a release valve that mounted at the fitting on the storage lank 431 can replace the breathing channel 437. In this case the storage tank 431 becomes a pressured storage tank. The release valve may become a breathing channel. The heat transfer speed of this kind of pressured tank is not as good as an opened tank. Further more, there is a concern of the safety for fi-equent on/off release valve.
