Definitions
- the present invention relates generally to solar power collection panels for use in heating water. More specifically, the present invention is a system that collects solar power and structure-generated heat in a solar panel assembly and transfers a portion of the collected heat energy to water flowing through a manifold of tubes.
- the solar panel assembly is configured for scalability, arranged to simply and easily allow multiple instances (modules) of the assembly to be connected or coupled in an array for increasing the overall heating capacity of the system.
- U.S. Patent Application 20080310913 by Urban, et al., teaches a “fixture for attaching a profile rail having an undercut longitudinal groove to another component, as well as an arrangement of this fixture.”
- the Urban et al application details a fixture “that can generate a statically-sound attachment universally between the profile rail and components, and is at the same time particularly fast and simple to install, as well as inexpensive to fabricate.”
- the primary goal of the invention is to reduce costs and complexity of installation for mechanisms for attaching a solar panel to a structure.
- What is also needed is a means for mounting a solar panel assembly to a structure, wherein the attachment mechanism is easy to install and mechanically secures a solar panel assembly in a way that keeps the assembly mechanically stable and secured through a wide range of environmental temperature changes and wind conditions.
- Such a solar panel assembly mounting means should also be easy to dismantle and disassemble for maintenance or system expansion purposes.
- the present invention is an inexpensive modular solar panel system arranged so as to facilitate the connection of multiple instances of the same solar panel assembly in a single connected array to increase the overall surface area used for collecting heat energy, and thus the overall system capacity for heating water.
- the connection and coupling features allow the end user to expand the solar panel array (and its capacity) only as needed, in small, affordable increments. The end user needs to purchase and add only one, or a few new panels to the array as necessary or desirable. This reduces the cost and complexity for each system expansion.
- the solar panel assembly of the present invention utilizes radiated energy from the Sun, as well as the heat energy radiating (and convectively transferred) from the structures to which the assembly is mounted, to raise the temperature of water.
- the inventive solar panel may be used to reduce the amount of commercial energy required to heat a swimming pool, spa, or domestic water supply.
- the top surface of the panel is heated by the Sun's radiated energy, and some of the heat energy of the heated panel is transferred to water flowing through a manifold of tubes integrated in the panel.
- thermal water solar panel of the present invention is increased when it is installed on the roof of a house, or a similar structure, where heat energy radiating and rising convectively from the structure is transferred to the bottom surface of the panel.
- This heat source adds to any heat energy acquired by solar insolation, thus increasing the overall amount of heat energy available for transfer to the water flowing through the manifold of tubes that are integrated into the solar panel assembly.

- each one of a first and second tube manifold assembly 100 a , 100 b includes an array of small-diameter tubes, which is termed the thin tube array.
- Two such arrays 114 , 115 are shown in this view, each showing the thin tubes disposed in substantially a single plane and connected at each end to a fluid port disposed on the interior side of each large tube manifold.
- the large diameter tubes comprise, respectively, a large tube inlet manifold, 101 a and 101 a ′, and a large tube outlet manifold 101 b and 101 b ′, for the first and second manifold assemblies, respectively.
- the large tube inlet and outlet manifolds lie in generally the same plane as the small diameter tubes, have a longitudinal axis perpendicular to the longitudinal axis of the smaller-diameter tubes.
- Each thin tube array 114 , 115 opens into a large tube manifold 101 a , 101 a ′, 101 b , 101 b ′ at each end, allowing water forced into the large tube inlet manifolds 101 a and 101 a ′ to flow through the multiple instances of thin tube array 114 , 115 into a first large tube outlet manifold 101 b and then into a second 101 b ′ and successor (if applicable) large tube outlet manifolds. With one end of the connected large tube inlet manifolds blocked (e.g.
- the tube manifold assembly is fabricated from generally rigid extruded plastic tubing, which is an efficient material for absorbing radiated heat (such as from the Sun).
- the tube manifold assembly can be made in various lengths (measured as the length of the two parallel instances of thin tube array 114 , 115 ). For instance, 3.9 meter, 3.4 meter, 2.9 meter, and 1.4 meter lengths are particularly useful in residential housing applications. Additionally, while a generally linear relationship of connected large tube inlet and outlet manifolds is contemplated, the system will easily accommodate direction changes with angled or curved fittings, wherein field cut or predetermined intermediate lengths of large tubing are provided to bring the ends of the inlet outlet manifolds of subsequently placed modules into alignment.
- FIG. 1 It can also be seen, in FIG. 1 , that there are multiple instances of thin tube clip 102 , each oriented parallel to the large tube manifolds 101 a through 101 b ′ et seq., and extending transversely across all instances of thin tube array 114 , 115 .
- the thin tube clips 102 are spaced apart from one another and are preferably distributed generally evenly between each of the large tubes 101 a through 101 b ′ et seq., and are used to hold the thin tube arrays in a parallel orientation.
- the thin tube clips are linear rods or sticks with comb-like tines or fingers that engage and capture the sides of each thin tube with a snap fit connection.
- thin tube clip bridge 103 is used to mechanically connect the ends of aligned thin tube clips 102 with a snap or friction fit coupling, thus providing additional stability and strength to the combined assemblies.
- the thin tube clip bridge includes a base with a U-shaped channel running longitudinally and into which the thin tube clip is inserted with a snap or friction fit connection.
- Mounting clamp base 104 is used to mount the tube manifold assembly to a building roof or other surface.
- Mounting clamp base 104 includes a generally flat bottom and can be secured to a roof by using screws to directly attach it, or by bolting it to any appropriate adaptive mechanism. After the mounting clamp base 104 is attached to a roof or other surface, large tube manifolds 101 a through 101 b ′ and more, if provided, are positioned to rest in the arcuate cradle of mounting clamp base 104 , thus orienting the plane of the entire assembly substantially parallel to the surface upon which it is mounted.
- mounting clamp top 105 is placed over each mounting clamp base 104 , and then snapped onto the mounting clamp base 104 to secure itself around a portion of the large tube manifold.
- the mounting clamp top like the mounting clamp base, includes an arcuate interior portion that wraps around a portion of the large tube manifold. Accordingly, mounting clamp base 104 , and a corresponding mounting clamp top 105 , are shaped to form a pair of opposing arcuate jaws that capture and retain the bottom, one side, top, and a portion of the opposite side of a large tube manifold. They are provided with coupling elements that allow mounting clamp top 105 to be snapped into a locking engagement with mounting clamp base 104 (see details of this locking engagement in the description of FIG. 3 ).
- mounting clamp top 105 and a mounting clamp base 104 can be unlocked with ease, and the two pieces can be pulled apart to allow the entire tube manifold assembly to be removed from an installed array. Note, however, that while mounting clamp top 105 and a mounting clamp base 104 can be unlocked with ease, the process requires specific mechanical actions that cannot be accomplished by wind, ambient temperature, or small animal activities. Therefore, they will not become unlocked inadvertently under ordinary environmental conditions.
- a tube manifold assembly is installed onto a roof or other surface, one end of a first large tube outlet manifold 101 b is sealed off using water input tube sealing plug 107 , and the opposite end of the second large tube inlet manifold 101 a ′ is sealed off using water output tube sealing plug 113 . This leaves open one end of one of the large tube manifolds in the overall tube manifold assembly.
- a source of pressurized water is attached to the open end of the first large tube inlet manifold 101 , and a water outlet line or hose is connected to the open end of the second or subsequent large tube manifold 101 b ′ (or open end of a successor large tube inlet manifold, depending on the flow pattern desired), thus allowing heated water to exit the assembly and flow to a desired destination.
- each instance of large tube manifold 101 a through 101 b ′ of a tube manifold assembly can instead be coupled with an identical large tube manifold 101 a ′′ and 101 b ′′ (not shown) of another instance of a tube manifold assembly by using a manifold coupling adapter 106 and lock nut 108 , along with one each of large O-ring 109 and small O-ring 110 .
- a manifold coupling adapter 106 and lock nut 108 along with one each of large O-ring 109 and small O-ring 110 .
- manifold coupling adapter 106 can be screwed into the internal threading of a large tube manifold 101 of the tube manifold assembly using, for instance, a small O-ring 110 , to seal the connection.
- lock nut 108 With the small opening of lock nut 108 disposed between the flange of manifold coupling adapter 106 and the lip of large tube manifold 101 a , lock nut 108 is still rotatable, and its large opening has internal threads sized to mate with the external threading of a second large tube manifold 101 a ′ of a large tube outlet manifold.
- the rotatable lock nut 108 is used to physically secure the large tube manifold of one tube manifold assembly to the externally-threaded end of a second large tube manifold of another tube manifold assembly.
- Large O-ring 109 is used to seal the connection between the connected ends of large tube manifolds with the flange of manifold coupling adapter 106 .
- Coupling first and second instances of the tube manifold assembly in this manner in this way provides a reliable waterproof seal where the large tube manifold assemblies of each large tube inlet and outlet manifold assembly are joined together, while expanding the water heating capacity of the system.
- the method of sealing one tube to another is through the use of a clamp and gasket combination.
- the present invention uses a method of attaching (and sealing) one large tube manifold to another (for attaching two solar panel assemblies into a single array), which has a higher degree of reliability and is easy to use when installing the assemblies on a roof.
- every other end of both the large tube inlet manifolds and the large tube outlet manifolds can be capped in a staggered pattern, such that water flows first into the first large tube manifold assembly 101 a , then through the first thin tube array 114 , then into and through the first large tube outlet manifold 101 b , into the second large tube outlet manifold 101 b ′, through second thin tube array 115 , into second large tube inlet manifold 101 a ′, and then either out for recirculation or into the next large tube inlet manifold of connected successor modules.
- This back and forth, or sinuous flow pattern of the water through the system maximizes the time available for heat transfer from the tubes to the fluid.
- a disk element or other closure can be provided as a fitting or part of a fitting interposed between connected inlet or outlet manifolds.
- lock nut 108 can be provided with a disk closure in its center, rather than being open.
- FIG. 2 there is provided a more detailed cross-sectional view of how multiple instances of the solar panel assembly are mechanically connected.
- large tube outlet manifold 101 b of one tube manifold assembly is connected to a second large tube outlet manifold 101 b ′.
- the first large tube outlet manifold 101 b is mounted to a surface and is secured by mounting clamp base 104 and mounting clamp top 105 in cooperation with expansion clip 400 .
- the thin tube arrays 114 , 115 extend perpendicular to the rigid large tubes 101 b , 101 b ′ of each instance of large tube outlet manifold, and they are secured in substantially the same plane by thin tube clip 102 .
- Thin tube clip bridge 103 connects instances of thin tube clip 102 between the two connected rigid tube manifold assemblies [see also FIG. 7 ].
- connection between the first and second instances of the large tube manifolds is accomplished as follows:
- small O-ring 110 is positioned between the first large tube manifold 101 b and manifold coupling adapter 106 .
- the small opening of lock nut 108 is disposed over the threaded end of manifold coupling adapter 106 , with the large opening lock nut 108 oriented to face the unthreaded end of manifold coupling adapter 106 .
- the outside threads of manifold coupling adapter 106 are then screwed into the inside threads of large tube outlet manifold 101 b .
- lock nut 108 are threaded onto the exterior threads of the second large tube outlet manifold 101 b ′. This action compresses large O-ring 109 between the flange of manifold coupling adapter 106 and the end of the second large tube outlet manifold, thereby creating a watertight seal. This also causes the two large tube manifolds to easily be connected in a physically secure manner.
- mounting clamp base 104 has a pair of mounting holes 301 that are used for securing mounting clamp base 104 to a surface.
- expansion clip 400 is secured to mounting clamp top 105 by snapping split round protrusion 403 into a snap fit connection in the round receptacles 306 found on mounting clamp top 105 .
- mounting clamp top 105 can have its split round protrusions 403 snapped into mating round receptacle 306 found on mounting clamp top 105 during the manufacturing process at the factory, thus not requiring this step to be performed during the installation.
- expansion clip 400 a can be integrally molded into clamp top 105 a , obviating the need for the above-described structural elements needed to connect a discretely molded expansion clip to the clamp top.
- mounting clamp top 105 With either version of expansion clip 400 / 400 a secured to mounting clamp top 105 / 105 a , mounting clamp top 105 is positioned over the top of the instance of large tube outlet manifold 101 b . Pressing mounting clamp top 105 down onto the mounted instance of mounting clamp base 104 causes tension on expansion clip 400 / 400 a as it is compressed between mounting clamp top 105 / 105 a and the exterior wall of large tube manifold 101 b .
- Rectangular guide 302 provides a guiding protuberance for easily sliding rectangular guide 302 into rectangular receptacle 303 , thus causing the instances of locking base clip 304 to clip into base clip slot 305 .
- expansion clip 400 / 400 a which is used as described above to provide a pressured tensile grip on an instance of large tube outlet manifold 101 b that is mounted to a surface using mounting clamp base 104 and mounting clamp top 105 / 105 a .
- expansion clip 400 is secured to mounting clamp top 105 by pushing each instance of split round protrusions 403 into its mating instance of round receptacle 306 on mounting clamp top 105 .
- tension latching protrusion 404 extends just over the top of round receptacle 306 , and the outward tension of the individual legs of split round protrusion 403 causes tension latching protrusion 404 to expand outwards and clip over the exterior lip of the top of round receptacle 306 , thereby latching expansion clip 400 into place.
- expansion clip 404 a as shown in FIG. 6A , the clip is integrally formed in clamp top 105 a , thus obviating the need for connection apparatus for the clip, as described above. This is the preferred embodiment of the expansion clip as it is less expensive to manufacture in the injection molding process and does not include the split protrusion elements that make the clip vulnerable to damage and breaking.
- expansion clip 400 / 400 a With expansion clip 400 / 400 a attached to mounting clamp top 105 / 105 a , when mounting clamp top 105 / 105 a is secured to a mounted instance of mounting clamp base 104 (with an instance of large tube manifold clamped between them— FIGS. 5 and 6B ), mounting clamp top interface 401 of expansion clip 400 / 400 a is urged against the interior of mounting clamp top 105 / 105 a , and large tube manifold interface 402 is urged against the exterior wall of large tube outlet manifold 101 b .
- mounting clamp top interface 401 and large tube manifold interface 402 tend to retain their original positions with respect to one another, thus creating a constant source of pressure against a large tube manifold to hold it in place.
- mounting clamp top interface 401 in an undeformed configuration, is spaced apart from large tube manifold interface 402 but these elements are two curved portions joined by a bend 405 , formed of material sufficient resilient to allow decreases in the bend angle under the force of an expanding captured tube.
- FIGS. 5 and 6B there is shown how the large tube manifold (in this instance large tube outlet manifold 101 b , for purposes of illustration only) of the tube manifold assembly is secured into the mounting mechanism, which comprises mounting clamp base 104 , mounting clamp top 105 / 105 a and expansion clip 400 / 400 a .
- the large tube manifold is clamped between mounting clamp base 104 and mounting clamp top 105 / 105 a , with expansion clip 400 / 400 a , thereby providing pressure between mounting clamp top 105 / 105 a and the exterior wall of large tube manifold.
- expansion clip 400 is attached to mounting clamp top 105 by pushing tension latching protrusions 404 of split round protrusions 403 through, and latched over the upper lip of, round receptacles 306 for the split protrusions.
- expansion clip 400 a is integrally formed in mounting clamp top 105 a .
- Mounting clamp base 104 is secured to mounting clamp top 105 by inserting locking base clip 303 into, and pressure-latched to, base clip slot 305 of mounting clamp top 105 a.
- the expansion clip ensures that pressure is exerted against large tube manifolds by large tube manifold interface 402 of expansion clip 400 / 400 a . This pressure is maintained because mounting clamp top interface 401 of expansion clip 400 is secured against the interior surfaces of mounting clamp top 105 / 105 a and mounting clamp base 104 (those surfaces facing the large tube manifold).
- the present invention is a modular thermal solar panel water heating system that includes a plurality of solar heating modules, each including a large tube inlet manifold, a large tube outlet manifold, a thin tube array disposed between and in fluid communication with each of the large tube inlet manifold and large tube outlet manifold, and fittings for coupling each solar heating module to an adjoining solar heating module.
- Water is provided to a first module in the plurality of modules, thus defining an inlet end of the panel array; water exits the plurality of modules through an outlet after passing through a succession of adjoined modules, and such fluid flow includes first passing into a large tube manifold and then through a thin tube array.
- the flow can be from one side only (i.e., the large tube inlet manifold side) across the thin tube array, into the large tube outlet manifolds, and then out the water outlet disposed in the final outlet manifold in the array.
- water can flow back and forth across the modules, first from the large tube inlet manifold across a thin tube array, into a first large tube outlet manifold, next into a second large tube outlet manifold, and across a thin tube array into a second large tube inlet manifold, and so on, all accomplished by configuring a series of plugs set between large tube manifolds in a staggered pattern.
- the fittings connecting the large tube manifolds are conventional coupling nuts, locking nuts, flanges, O-rings or gaskets, and the like. Variations from a purely linear panel array can be accommodated using angles and bends in the fittings with tube extensions that compensate for the different distances of the large tube inlet manifolds and large tube outlet manifolds from the same elements in the adjoining panel module.
- the system includes a mounting system and mounting clamps that accommodate component expansion due to changing environmental conditions.
Abstract
A modular thermal solar panel water heating system with a plurality of solar heating modules, each including a inlet manifolds and outlet manifolds and a thin tube array disposed between and in fluid communication with the inlet and outlet manifolds. Mounting and clamping apparatus attach the solar heating modules to a surface and providing secure clamping pressures on clamped elements even as clamped elements expand and contract. Fittings provide a watertight coupling between adjoining modules and bring each module into fluid communication with at least one adjoining module. In a panel array, one module includes a water inlet for connection to a source of water under pressure and another module includes a water outlet. A set of plugs are disposed on the manifolds in a configuration that ensures that water introduced into the water inlet flows across at least one thin tube array before exiting the water outlet.

- 1. Field of the Invention
- The present invention relates generally to solar power collection panels for use in heating water. More specifically, the present invention is a system that collects solar power and structure-generated heat in a solar panel assembly and transfers a portion of the collected heat energy to water flowing through a manifold of tubes. The solar panel assembly is configured for scalability, arranged to simply and easily allow multiple instances (modules) of the assembly to be connected or coupled in an array for increasing the overall heating capacity of the system.
- 2. Discussion of Related Art Including Information Disclosed Under 37 CFR §§1.97, 1.98
- Capturing and using solar radiation energy to heat water is well known. With the continual rise in the costs of commercial energy generation, and in view of the potential threat of global climate change and atmospheric pollution due to the overuse of fossil fuel energy sources, the demand for solar energy water heating systems is increasing.
- A key limitation in currently available thermal water solar systems, however, is that the commercially available solutions are very costly and require professional expertise for installation (further increasing the initial installation and future expansion costs of such systems). Thus, various solutions have been proposed to address the high cost and complexity of installing solar panel systems.
- For example, in U.S. Pat. No. 6,948,687 (Shatzky, Sep. 27, 2005) discloses a solar panel system for installation on a building rooftop which is purportedly inexpensive and easy to install initially. The invention by Shatzky is adaptable to many of the various types of roofing surfaces to which a solar panel may be attached. However, while Shatzky discloses an inexpensive and adaptable mounting mechanism, it does not enable the installer to easily connect multiple instances of the same solar panel assembly into a single array in a modular fashion. Shatzky also fails to appreciate the need for (and thus does not disclose) apparatus to accommodate and tolerate the expansion of structural elements and connectors. For a modular system, there is needed an expansion clip or comparable device that fits into the mounting mechanism and that allows expansion and contraction of the solar panel assembly without compromising the integrity of the connections in the assembly.
- Further, U.S. Patent Application 20080310913, by Urban, et al., teaches a “fixture for attaching a profile rail having an undercut longitudinal groove to another component, as well as an arrangement of this fixture.” The Urban et al application details a fixture “that can generate a statically-sound attachment universally between the profile rail and components, and is at the same time particularly fast and simple to install, as well as inexpensive to fabricate.” The primary goal of the invention is to reduce costs and complexity of installation for mechanisms for attaching a solar panel to a structure.
- Again, however, Urban fails to disclose a solar panel assembly where the installer can easily connect multiple instances of the same module for the solar panel assembly into a connected solar panel array. And as with Shatzky, Urban et al fail to appreciate the need for (and thus do not disclose) an expansion clip or comparable element that fits into the mounting mechanism and that allows expansion and contraction of the solar panel assembly during temperature fluctuations without compromising the integrity of the connections in the assembly.
- None of the known prior art, taken either singly or in combination, describes or suggests the present invention as described herein.
- What remains after consideration of the prior art is an inexpensive solar panel assembly that has a coupling and connecting system facilitating the addition of multiple instances of the same general solar panel assembly to form a single operative array. Such a connection increases the overall surface area used for collecting heat energy, and thus the overall system capacity for heating water.
- Additionally, what is needed is a solar panel assembly that allows the end user to purchase only as much solar energy capturing capacity (in terms of solar panels) as is necessary, thereby allowing the end user to expand the solar panel array (and its capacity) only as needed, in small, affordable increments.
- What is also needed is a means for mounting a solar panel assembly to a structure, wherein the attachment mechanism is easy to install and mechanically secures a solar panel assembly in a way that keeps the assembly mechanically stable and secured through a wide range of environmental temperature changes and wind conditions. Such a solar panel assembly mounting means should also be easy to dismantle and disassemble for maintenance or system expansion purposes.
- These features, and others, are found in the solar panel assembly described in the present application.
- The present invention is an inexpensive modular solar panel system arranged so as to facilitate the connection of multiple instances of the same solar panel assembly in a single connected array to increase the overall surface area used for collecting heat energy, and thus the overall system capacity for heating water. The connection and coupling features allow the end user to expand the solar panel array (and its capacity) only as needed, in small, affordable increments. The end user needs to purchase and add only one, or a few new panels to the array as necessary or desirable. This reduces the cost and complexity for each system expansion.
- The solar panel assembly of the present invention utilizes radiated energy from the Sun, as well as the heat energy radiating (and convectively transferred) from the structures to which the assembly is mounted, to raise the temperature of water. The inventive solar panel may be used to reduce the amount of commercial energy required to heat a swimming pool, spa, or domestic water supply.
- When the solar panel is installed in a location where maximum exposure to the Sun is possible, the top surface of the panel is heated by the Sun's radiated energy, and some of the heat energy of the heated panel is transferred to water flowing through a manifold of tubes integrated in the panel.
- The effectiveness of the thermal water solar panel of the present invention is increased when it is installed on the roof of a house, or a similar structure, where heat energy radiating and rising convectively from the structure is transferred to the bottom surface of the panel. This heat source adds to any heat energy acquired by solar insolation, thus increasing the overall amount of heat energy available for transfer to the water flowing through the manifold of tubes that are integrated into the solar panel assembly.
- The invention will be better understood and the objects and advantages of the invention other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:

FIG. 7 is a perspective view showing the connecting of tube clips by the tube clip bridge. - Referring now to
FIG. 1 , there is shown in an exploded perspective view the components comprising two instances (or modules) 100 a, 100 b, of the tube manifold assembly of the present invention. It can be seen that each one of a first and secondtube manifold assembly such arrays thin tubes 102 of thethin tube arrays tube outlet manifold thin tube array large tube manifold tube inlet manifolds thin tube array tube outlet manifold 101 b and then into a second 101 b′ and successor (if applicable) large tube outlet manifolds. With one end of the connected large tube inlet manifolds blocked (e.g. capped or plugged), as pressurized water flows into one large tube manifold 101, it passes through the multiple instances ofthin tube array - Preferably, the tube manifold assembly is fabricated from generally rigid extruded plastic tubing, which is an efficient material for absorbing radiated heat (such as from the Sun).
- The tube manifold assembly can be made in various lengths (measured as the length of the two parallel instances of
thin tube array 114, 115). For instance, 3.9 meter, 3.4 meter, 2.9 meter, and 1.4 meter lengths are particularly useful in residential housing applications. Additionally, while a generally linear relationship of connected large tube inlet and outlet manifolds is contemplated, the system will easily accommodate direction changes with angled or curved fittings, wherein field cut or predetermined intermediate lengths of large tubing are provided to bring the ends of the inlet outlet manifolds of subsequently placed modules into alignment. - It can also be seen, in
FIG. 1 , that there are multiple instances ofthin tube clip 102, each oriented parallel to thelarge tube manifolds 101 a through 101 b′ et seq., and extending transversely across all instances ofthin tube array large tubes 101 a through 101 b′ et seq., and are used to hold the thin tube arrays in a parallel orientation. The thin tube clips are linear rods or sticks with comb-like tines or fingers that engage and capture the sides of each thin tube with a snap fit connection. - When two modules of the tube manifold assembly are connected together, thin
tube clip bridge 103 is used to mechanically connect the ends of aligned thin tube clips 102 with a snap or friction fit coupling, thus providing additional stability and strength to the combined assemblies. As seen inFIG. 1 andFIG. 7 , the thin tube clip bridge includes a base with a U-shaped channel running longitudinally and into which the thin tube clip is inserted with a snap or friction fit connection. - Mounting
clamp base 104 is used to mount the tube manifold assembly to a building roof or other surface. Mountingclamp base 104 includes a generally flat bottom and can be secured to a roof by using screws to directly attach it, or by bolting it to any appropriate adaptive mechanism. After the mountingclamp base 104 is attached to a roof or other surface,large tube manifolds 101 a through 101 b′ and more, if provided, are positioned to rest in the arcuate cradle of mountingclamp base 104, thus orienting the plane of the entire assembly substantially parallel to the surface upon which it is mounted. - Once the large tube inlet and outlet manifold assemblies are positioned to rest in the cradle of the mounted mounting
clamp bases 104, a mountingclamp top 105 is placed over each mountingclamp base 104, and then snapped onto the mountingclamp base 104 to secure itself around a portion of the large tube manifold. The mounting clamp top, like the mounting clamp base, includes an arcuate interior portion that wraps around a portion of the large tube manifold. Accordingly, mountingclamp base 104, and a corresponding mountingclamp top 105, are shaped to form a pair of opposing arcuate jaws that capture and retain the bottom, one side, top, and a portion of the opposite side of a large tube manifold. They are provided with coupling elements that allow mountingclamp top 105 to be snapped into a locking engagement with mounting clamp base 104 (see details of this locking engagement in the description ofFIG. 3 ). - Additionally, the locking engagement between a mounting
clamp top 105 and a mountingclamp base 104 can be unlocked with ease, and the two pieces can be pulled apart to allow the entire tube manifold assembly to be removed from an installed array. Note, however, that while mountingclamp top 105 and a mountingclamp base 104 can be unlocked with ease, the process requires specific mechanical actions that cannot be accomplished by wind, ambient temperature, or small animal activities. Therefore, they will not become unlocked inadvertently under ordinary environmental conditions. - Once a tube manifold assembly is installed onto a roof or other surface, one end of a first large
tube outlet manifold 101 b is sealed off using water inputtube sealing plug 107, and the opposite end of the second largetube inlet manifold 101 a′ is sealed off using water outputtube sealing plug 113. This leaves open one end of one of the large tube manifolds in the overall tube manifold assembly. A source of pressurized water is attached to the open end of the first large tube inlet manifold 101, and a water outlet line or hose is connected to the open end of the second or subsequentlarge tube manifold 101 b′ (or open end of a successor large tube inlet manifold, depending on the flow pattern desired), thus allowing heated water to exit the assembly and flow to a desired destination. - Rather than having an end capped, each instance of
large tube manifold 101 a through 101 b′ of a tube manifold assembly, can instead be coupled with an identicallarge tube manifold 101 a″ and 101 b″ (not shown) of another instance of a tube manifold assembly by using amanifold coupling adapter 106 and locknut 108, along with one each of large O-ring 109 and small O-ring 110. This is possible because each large tube manifold of the tube manifold assembly has one end threaded internally, and its other end threaded externally, in an arrangement that allows the assemblies to be threadably coupled using threaded fittings. - The external threading of
manifold coupling adapter 106 can be screwed into the internal threading of a large tube manifold 101 of the tube manifold assembly using, for instance, a small O-ring 110, to seal the connection. With the small opening oflock nut 108 disposed between the flange ofmanifold coupling adapter 106 and the lip oflarge tube manifold 101 a,lock nut 108 is still rotatable, and its large opening has internal threads sized to mate with the external threading of a secondlarge tube manifold 101 a′ of a large tube outlet manifold. In this configuration, therotatable lock nut 108 is used to physically secure the large tube manifold of one tube manifold assembly to the externally-threaded end of a second large tube manifold of another tube manifold assembly. Large O-ring 109 is used to seal the connection between the connected ends of large tube manifolds with the flange ofmanifold coupling adapter 106. - Coupling first and second instances of the tube manifold assembly in this manner in this way provides a reliable waterproof seal where the large tube manifold assemblies of each large tube inlet and outlet manifold assembly are joined together, while expanding the water heating capacity of the system.
- In the prior art, where rigid tubes are used in a solar panel assembly, the method of sealing one tube to another is through the use of a clamp and gasket combination. The present invention uses a method of attaching (and sealing) one large tube manifold to another (for attaching two solar panel assemblies into a single array), which has a higher degree of reliability and is easy to use when installing the assemblies on a roof.
- In an alternative installation, every other end of both the large tube inlet manifolds and the large tube outlet manifolds can be capped in a staggered pattern, such that water flows first into the first large
tube manifold assembly 101 a, then through the firstthin tube array 114, then into and through the first largetube outlet manifold 101 b, into the second largetube outlet manifold 101 b′, through secondthin tube array 115, into second largetube inlet manifold 101 a′, and then either out for recirculation or into the next large tube inlet manifold of connected successor modules. This back and forth, or sinuous flow pattern of the water through the system maximizes the time available for heat transfer from the tubes to the fluid. To accomplish the staggered pattern, a disk element or other closure can be provided as a fitting or part of a fitting interposed between connected inlet or outlet manifolds. For instance,lock nut 108 can be provided with a disk closure in its center, rather than being open. Thus, while providing a means to couple large tube manifolds, it can also be employed to stop water flow to a successor large tube manifold and thereby force water through two small tube arrays before it is returned to the successor tube. In this way, water will travel through a number of small tube arrays before leaving an outlet for use. - Referring now to
FIG. 2 , there is provided a more detailed cross-sectional view of how multiple instances of the solar panel assembly are mechanically connected. Here it can be seen that largetube outlet manifold 101 b of one tube manifold assembly is connected to a second largetube outlet manifold 101 b′. The first largetube outlet manifold 101 b is mounted to a surface and is secured by mountingclamp base 104 and mountingclamp top 105 in cooperation withexpansion clip 400. Thethin tube arrays large tubes thin tube clip 102. Thintube clip bridge 103 connects instances ofthin tube clip 102 between the two connected rigid tube manifold assemblies [see alsoFIG. 7 ]. - The connection between the first and second instances of the large tube manifolds is accomplished as follows:
- First, small O-
ring 110 is positioned between the firstlarge tube manifold 101 b andmanifold coupling adapter 106. Next, the small opening oflock nut 108 is disposed over the threaded end ofmanifold coupling adapter 106, with the largeopening lock nut 108 oriented to face the unthreaded end ofmanifold coupling adapter 106. The outside threads ofmanifold coupling adapter 106 are then screwed into the inside threads of largetube outlet manifold 101 b. This seals the connection between the first large tube outlet manifold 101 and the threaded side of the flange ofmanifold coupling adapter 106, while allowinglock nut 108 to rotate, yet keepinglock nut 108 secured behind the flange ofmanifold coupling adapter 106. Following this, large O-ring 109 is positioned between the second largetube outlet manifold 101 b′ and the non-threaded flange ofmanifold coupling adapter 106. Next, the exterior-threaded end of the second largetube outlet manifold 101 b′ is butted up against the non-threaded side of the flange ofmanifold coupling adapter 106. Finally, the interior threads oflock nut 108 are threaded onto the exterior threads of the second largetube outlet manifold 101 b′. This action compresses large O-ring 109 between the flange ofmanifold coupling adapter 106 and the end of the second large tube outlet manifold, thereby creating a watertight seal. This also causes the two large tube manifolds to easily be connected in a physically secure manner. - As can be seen in
FIG. 2 , connecting additional instances of the rigid tube manifold assemblies is easily done by simply repeating the process with each new assembly that is added to the array of assemblies. - Referring now to
FIG. 3A andFIG. 3B there are show exploded views of the mounting clamp assembly used to secure the solar panel(s) to a surface. In these drawings, mountingclamp base 104 has a pair of mountingholes 301 that are used for securing mountingclamp base 104 to a surface. - Once mounting
clamp base 104 has been secured to a surface, a large tube manifold 101 is positioned to rest in the cradle of mountingclamp base 104. Then,expansion clip 400 is secured to mountingclamp top 105 by snapping split roundprotrusion 403 into a snap fit connection in theround receptacles 306 found on mountingclamp top 105. Note that, alternatively, mountingclamp top 105 can have its split roundprotrusions 403 snapped into mating roundreceptacle 306 found on mountingclamp top 105 during the manufacturing process at the factory, thus not requiring this step to be performed during the installation. In the alternative, and as shown inFIGS. 6A-6B ,expansion clip 400 a can be integrally molded into clamp top 105 a, obviating the need for the above-described structural elements needed to connect a discretely molded expansion clip to the clamp top. - With either version of
expansion clip 400/400 a secured to mounting clamp top 105/105 a, mountingclamp top 105 is positioned over the top of the instance of largetube outlet manifold 101 b. Pressing mountingclamp top 105 down onto the mounted instance of mountingclamp base 104 causes tension onexpansion clip 400/400 a as it is compressed between mountingclamp top 105/105 a and the exterior wall oflarge tube manifold 101 b.Rectangular guide 302 provides a guiding protuberance for easily slidingrectangular guide 302 intorectangular receptacle 303, thus causing the instances of lockingbase clip 304 to clip intobase clip slot 305. This latches mountingclamp top 105/105 a onto mountingclamp base 104, thus securing largetube outlet manifold 101 b. Note that the tension ofexpansion clip tube outlet manifold 101 b allows for some expansion and contraction of large tube manifold 101 without losing the secure hold that keeps largetube outlet manifold 101 b in position. It will be readily appreciated that the clamping system described is identical for each large tube inlet and outlet manifold. - Referring now to
FIGS. 5 and 6B there is seen a drawing showingexpansion clip 400/400 a, which is used as described above to provide a pressured tensile grip on an instance of largetube outlet manifold 101 b that is mounted to a surface using mountingclamp base 104 and mountingclamp top 105/105 a. In connection with the first embodiment ofclamp top 105, and as seen inFIG. 3 ,expansion clip 400 is secured to mountingclamp top 105 by pushing each instance of splitround protrusions 403 into its mating instance ofround receptacle 306 on mountingclamp top 105. When split roundprotrusion 403 is fully inserted intoround receptacle 306,tension latching protrusion 404 extends just over the top ofround receptacle 306, and the outward tension of the individual legs of split roundprotrusion 403 causestension latching protrusion 404 to expand outwards and clip over the exterior lip of the top ofround receptacle 306, thereby latchingexpansion clip 400 into place. In the alternative embodiment of expansion clip 404 a, as shown inFIG. 6A , the clip is integrally formed in clamp top 105 a, thus obviating the need for connection apparatus for the clip, as described above. This is the preferred embodiment of the expansion clip as it is less expensive to manufacture in the injection molding process and does not include the split protrusion elements that make the clip vulnerable to damage and breaking. - With
expansion clip 400/400 a attached to mounting clamp top 105/105 a, when mountingclamp top 105/105 a is secured to a mounted instance of mounting clamp base 104 (with an instance of large tube manifold clamped between them—FIGS. 5 and 6B ), mountingclamp top interface 401 ofexpansion clip 400/400 a is urged against the interior of mountingclamp top 105/105 a, and largetube manifold interface 402 is urged against the exterior wall of largetube outlet manifold 101 b. Because the material from whichexpansion clip 400/400 a is fabricated has a tensile property, mountingclamp top interface 401 and largetube manifold interface 402 tend to retain their original positions with respect to one another, thus creating a constant source of pressure against a large tube manifold to hold it in place. As can be seen inFIG. 4 , in an undeformed configuration, mountingclamp top interface 401 is spaced apart from largetube manifold interface 402 but these elements are two curved portions joined by abend 405, formed of material sufficient resilient to allow decreases in the bend angle under the force of an expanding captured tube. This simple snap together design of mounting clamp base, mounting clamp top, and expansion clip makes the installation, maintenance, expansion, and removal of the system remarkably easy. - Temperature changes or wind conditions that cause large tube manifolds to change outside diameter (due to expansion, contraction or shape distortion) are automatically compensated for by the ability of
expansion clip 400/400 a to expand and contract to accommodate changes in the large tube caused by the environmental conditions. The result is that large tube manifolds are kept in a stable and secure position even under varying environmental conditions. - Referring next to
FIGS. 5 and 6B , there is shown how the large tube manifold (in this instance largetube outlet manifold 101 b, for purposes of illustration only) of the tube manifold assembly is secured into the mounting mechanism, which comprises mountingclamp base 104, mountingclamp top 105/105 a andexpansion clip 400/400 a. In this drawing it can be seen that the large tube manifold is clamped between mountingclamp base 104 and mountingclamp top 105/105 a, withexpansion clip 400/400 a, thereby providing pressure between mountingclamp top 105/105 a and the exterior wall of large tube manifold. - In a first embodiment,
expansion clip 400 is attached to mountingclamp top 105 by pushingtension latching protrusions 404 of splitround protrusions 403 through, and latched over the upper lip of,round receptacles 306 for the split protrusions. In another embodiment,expansion clip 400 a is integrally formed in mounting clamp top 105 a. Mountingclamp base 104 is secured to mountingclamp top 105 by insertinglocking base clip 303 into, and pressure-latched to,base clip slot 305 of mounting clamp top 105 a. - In either configuration of the clamp top, the expansion clip ensures that pressure is exerted against large tube manifolds by large
tube manifold interface 402 ofexpansion clip 400/400 a. This pressure is maintained because mountingclamp top interface 401 ofexpansion clip 400 is secured against the interior surfaces of mountingclamp top 105/105 a and mounting clamp base 104 (those surfaces facing the large tube manifold). - From the foregoing, it will be appreciated that in its most essential aspect, the present invention is a modular thermal solar panel water heating system that includes a plurality of solar heating modules, each including a large tube inlet manifold, a large tube outlet manifold, a thin tube array disposed between and in fluid communication with each of the large tube inlet manifold and large tube outlet manifold, and fittings for coupling each solar heating module to an adjoining solar heating module. Water is provided to a first module in the plurality of modules, thus defining an inlet end of the panel array; water exits the plurality of modules through an outlet after passing through a succession of adjoined modules, and such fluid flow includes first passing into a large tube manifold and then through a thin tube array. The flow can be from one side only (i.e., the large tube inlet manifold side) across the thin tube array, into the large tube outlet manifolds, and then out the water outlet disposed in the final outlet manifold in the array. Alternatively, water can flow back and forth across the modules, first from the large tube inlet manifold across a thin tube array, into a first large tube outlet manifold, next into a second large tube outlet manifold, and across a thin tube array into a second large tube inlet manifold, and so on, all accomplished by configuring a series of plugs set between large tube manifolds in a staggered pattern. The fittings connecting the large tube manifolds are conventional coupling nuts, locking nuts, flanges, O-rings or gaskets, and the like. Variations from a purely linear panel array can be accommodated using angles and bends in the fittings with tube extensions that compensate for the different distances of the large tube inlet manifolds and large tube outlet manifolds from the same elements in the adjoining panel module. Most notably, the system includes a mounting system and mounting clamps that accommodate component expansion due to changing environmental conditions.
- The foregoing description and the accompanying drawings show that an inexpensive solar panel array can be manufactured for easy installation onto a surface, and once installed, expansion is also easily achieved. The novel modular panel array system is physically stable in varying environmental conditions.
