Description

EDITORIAL NOTE There are 4 pages of description
DESCRIPTION
The present invention is described in detail below through two embodiments along with the accompanying drawings.
Referring to Fig. 1, this invention uses solar collectors 1 to gather solar heat energy, which is transmitted through conduction heat pipes 2 to a liquid-vapor two-phase system contained in a pressure vessel 3. The pressure vessel 3 is equipped with a safety valve 4 and a pressure gauge 5 for protection from excessive pressure. When the heat transmitted from the solar collectors heats the liquid inside the pressure vessel 3 to its boiling point, the liquid is converted to vapor, expanding the volume by several hundred times and generating a pressure of several hundred atmospheres. Such high pressure is sufficient to drive a motor 6. After driving the motor 6, the vapor at reduced pressure passes through a first check valve 14 and enters a cooler 15; optionally, a fan (not shown) can be installed to enhance the cooling efficiency of the cooler 15; after exiting the cooler 15, the vapor cools down below the boiling point and condenses into liquid, which then enters a reservoir 13 to be pumped by a pump 12 through a second check valve 16 back to the pressure vessel 3, thus completing the cycle. The pump 12 is connected to a liquid level controller 11 for the reservoir 13, and the liquid level controller 11 is connected to a control box 10, which controls the operation of both the pump 12 and the liquid level controller 11.
Besides carrying a load 7, the above-mentioned motor 6 also drives a generator 8. In turn, the generator 8 is connected through wires 18 to a battery 9 and the control box 10. The generator 8 and the battery 9 provide electricity for operating the pump 12 and the control box As shown in Fig. 1, the motor 6 can be powered by allowing the high-pressure vapor passing through a jet nozzle 17 to drive a series of turbine vanes.
Fig. 2 illustrates a second embodiment of the present invention. This embodiment is identical to the first embodiment shown in Fig. 1, except that the high-pressure vapor drives a 0 C, piston 19 to power the motor 6. One should note that other types of driving mechanisms can be used instead.
Fig. 3 illustrates a third embodiment of the present invention. This embodiment is C, identical to the first embodiment shown in Fig. 1, except that the conduction heat pipes are Cl IND replaced with a pump circulating a heating medium through the solar collectors 1, wherein the C, heating medium is heated, and through the pressure vessel 3, wherein the heating medium O releases its heat to the liquid in the pressure vessel 3 through a coil. Water is used as the Cl heating medium in this embodiment.
Fig. 4 illustrates a fourth embodiment of the present invention. This embodiment is identical to the second embodiment shown in Fig. 2, except that the conduction heat pipes are replaced with a pump circulating a heating medium through the solar collectors 1, wherein the heating medium is heated, and through the pressure vessel 3, wherein the heating medium releases its heat to the liquid in the pressure vessel 3 through a coil. Water is used as the heating medium in this embodiment.
The above-mentioned generator 8 can also be used for electrolysis of water to produce hydrogen for various applications.
The liquid in the pressure vessel 3 for the present invention is preferably propane, isobutane, Freons chlorofluorocarbons with the formula of CClnF 4 n or ammonia. The operating conditions when propane and ammonia, respectively, is used as the working liquid in the pressure vessel 3 are described in the following examples: Example 1 When propane is used as the working liquid, the temperature and pressure within the pressure vessel 3 are maintained at 45.6 0 C and 18.7 kg/cm 2 respectively; the pressure of the 2 S vapor exiting the first check valve 14 is about 15.5 kg/cm 2 and the vapor cools to about 30 0
C
0 Nl after the cooler Example 2 When ammonia is used as the working liquid, the temperature and pressure within the S pressure vessel 3 are 28.20C and 9.67 kg/cm 2 respectively; the pressure of the vapor exiting
INDI
the first check valve 14 is about 6.95 kg/cm2; and the vapor cools to about 7.80C after the S cooler While the invention has been described by way of examples and in terms of preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows the first embodiment of the present invention, wherein the high-pressure vapor passes through a jet nozzle to drive turbine vanes.
Fig. 2 shows the second embodiment of the present invention, wherein the high-pressure vapor drives a piston connected to a motor.
Fig. 3 shows a variant of the first embodiment of the present invention, wherein a pump is used to circulate a heating medium through the solar collectors.
Fig. 4 shows a variant of the second embodiment of the present invention, wherein a pump is used to circulate a heating medium through the solar collectors.
