Abstract
A solar heat collector (10) includes a closed container (12) for enclosing collector tubing (14) in a space, the container (12) having a transparent window (16) for receiving solar radiation (18) into the container (12) and a reflective support surface (20), opposite to the transparent window (16), for supporting collector tubing (14), and an array of collector tubing, the tubes (22) of the tubing (14) being generally arranged in parallel and spaced apart from another on the surface such that, in use, when solar radiation enters the container with an incidence angle of the component perpendicular to the tubing being between 0° and 70°, the radiation radiates the tubes and at least a portion of the reflective support surface between the tubes.
Claims
1. A solar heat collector, which includes: a closed container for enclosing collector tubing in a space, the container having a transparent window for receiving solar radiation into the container and a diffuse reflective support surface, opposite to the transparent window, for supporting collector tubing; and an array of collector tubing, the tubes of the tubing being generally arranged in parallel and spaced apart from another on the surface such that, in use, when solar radiation enters the container with an incidence angle of the component perpendicular to the tubing being between 0° and 70°, the radiation radiates the tubes and at least a portion of the reflective support surface between the tubes.
2. A solar heat collector as claimed in Claim 1 , wherein the tubes of the tubing are generally arranged in parallel and spaced apart from another on the surface such that, in use, when solar radiation enters the container with an incidence angle of the component perpendicular to the tubing being between 0° and 60°, the radiation radiates the tubes and at least a portion of the reflective support surface between the tubes.
3. A solar heat collector as claimed in Claim 3, wherein the reflective surface has a light reflectivity of about 80 as measured using the CIE (The International Commission on Illumination) system and an illuminant D 10°.
4. A solar heat collector as claimed in any one of the previous claims, wherein the tubes of the collector tubing are circular in cross section and generally equidistantly spaced from each other, the distance being half to one and a half of the diameter of the tubes.
5. A solar heat collector as claimed in Claim 4, wherein the distance is equal to the diameter of the tubes.
6. A solar heat collector as claimed in any one of the previous claims, wherein the tubes of the collector tubing are arranged in a series of generally planar-parallel spaced tubes of equal length and the collector further includes a pair of combining conduits for combining the ends, in fluid communication, of the tubes at respective opposed ends of the series of collector tubes.
7. A solar heat collector as claimed in Claim 6, wherein the container includes an insulating layer between the support surface and a corresponding opposed outer wall, other than the transparent window.
8. A solar heat collector as claimed in Claim 6 or Claim 7 , wherein the tubes of the collector tubing and the combining conduits are manufactured from an expandable plastics material.
9. A solar heat collector as claimed in Claim 8, which includes a reservoir in fluid communication with the collector tubing.
10. A solar heat collector as claimed in Claim 9 wherein one of the pair of combining conduits lead into the reservoir and the other combining conduit lead out of the reservoir to define a fluid flow circuit.
11. A solar heat collector as claimed in any one of the previous claims, which includes a support member for supporting the container in an orientation such that the reflective support surface and each collector tube is transverse to a plane defined by an average seasonal path of the sun across the sky from East to West due to the rotation of the earth.
12. A solar heat collector as claimed in Claim 11, which includes a housing for housing the reservoir, the housing forming the support member for supporting the container in said orientation.
13. A solar heat collector as claimed in Claim 12, wherein the support member for supporting the container in said orientation is a wall of the housing which abut with an outer wall of the container at edges thereof at a predetermined angle relative to each other such that the wall of the housing defines the support member, which, in use, supports the container in said orientation.
14. A solar heat collector as claimed in any one of claims 10 to 12, wherein the reservoir includes: a pipe of a polymeric material; a first closure configured to seal one end of the pipe; a second closure configured to seal the other end of pipe; an inlet and outlet leading into and out of the reservoir, the inlet and outlet being connectable to solar heat collector tubing; and an inlet and outlet leading into and out of the reservoir, respectively for charging and draining the reservoir.
15. A solar heat collector as claimed in Claim 14, wherein the polymeric material is selected from a plastics material.
16. A solar heat collector as claimed in any one of claims 9 to 12, wherein the reservoir is manufactured from a fibre re-enforced polymeric material.
17. A solar heat collector as claimed in Claim 14 or Claim 15, wherein the reservoir includes a clamping system for clamping the first and second closures into its respective closing positions such that it the reservoir can withstand a hydrostatic pressure of at least 400kPa.
18. A solar heat collector as claimed in Claim 17, wherein the clamping system comprises a pair of frames, one frame configured to locate the first closure and the other configured to locate the second closure, and a means for urging the frames towards each other such that the each closure sealingly closes the reservoir.
19. A solar heat collector as claimed in Claim 16, wherein the means for urging the frames toward each other is two or more strips along the length of the pipe, each end of each strip being configured to be fastened to a respective frame.
20. A solar heat collector as claimed in any one of claims 17 to 19, wherein the inlets and outlets are manufactured from an expandable plastics material.
21. A solar heat collector substantially as described herein with reference to the accompanying drawings.
