- 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.
- two couple inlet and outlet, 721 /722 and 723/724 may be arranged at the sidewall in any angle from 90- 180 degree.
- the units with two solar heat collectors arranged in 180 degree are the plane unit of building walls, fences and verandas.
- the units with two solar heat collectors arranged in 90 degree are the corner units.
- the heat driven and self-circulating solar heating and storage system should be and can be a compacted component.
- Fig. 6 when the solar heat collectors 780 and 760 are moved close to the fluid heating and storage tank and make the solar heat collector's sizes larger, a compacted solar heating and storage system will be find.
- each of the two couple of inlet/outlet ports is in a plumb line.
- 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.
- the heat driven self-circulating solar heating and storage system 100 comes into being 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 xxx, 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 stopples 4307 and 4308 are removed).
- This close-loop system connects to the atmosphere indirectly through the U- shaped tube 63.
- 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.
- 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 heat to the liquid in the tank. Then the liquid temperature drops and the volume of the liquid also drops too.
- 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.
- This head driven system has the functions of self-driven, self-control and self-circulating.
- 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.
- 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.
- the solar heating system may be equipped with single solar heat collector only.
- 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.
- Fig. 7 illustrates a heat driven self-circulating liquid heating and storage system 1 1 using a tank 40 with a interior installed heat exchanger. Comparing to Fig. 6, in Fig.7, a solar hear collector 760 is replaced by a 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 hear collector 760 and a other energy source heater. The figure shows that it is a fossil fuel heater 1200.
- the tank 40, solar heat collector 760 and the connections between them are similar as as mentioned in Fig.6.
- the coal heater 1200 comprises a central vacant cylinder (or other shaped e.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 partl205 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 tube 1207.
- 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 the tank will be heated.
- the processing in this heater system is similar with the processing of the solar heat collector system.
- the second heater shown in Gig. 7 is a coal heater, it can also be any alternative kind of non-solar heaters, e.g. fossil fuel (e.g. coal) heater, nature gas heater, biomass energy heater, (including biomass gasification heater), earth energy and air energy heater etc.
- fossil fuel e.g. coal
- nature gas heater e.g. coal
- biomass energy heater e.g. biomass gasification heater
- the heating liquid storage space of this kind of heater is much smaller than any other kind of liquid heater.
- one metal tube can be the storage container of the liquid to be heated in the heater.
- this heater can be a heater of earth or air heat energy.
- the heaters need a separator (e.g. separators 4308 and 4309 in Fig.2) to separate the liquid into two sub-systems.
- separators 4308 and 4309 in Fig.2 to separate the liquid into two sub-systems.
- 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 heat driven self-circulating fluid heating and storage system 140 with a heat appliance (here is a radiator 970, but not necessary).
- 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.
- 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 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.
- 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 returns to the bottom of the tank 30.
- a cover 721 with an active window 770 may be provided, (as shown in the figure 8, the window is opened upwardly). In fact the direction of the window can be varied.
- One or more fans may be provided in the cover to speed up the heat pervasion from the fin tube, (the fans did not show in the figure). If a canal is added to the window of cover 721 , the heated air can be transferred to a desire location (the canal did not show in the figure).
- 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, but it becomes an inlet when it is connected to a radiator,.
- 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 case, the fluid heating and storage tank need three couple inlets and outlets.
