Abstract

The invention relates to an interleave layer 7 used in a sandwich construction of a solar heat collector. The interleave layer comprises a sheet of twin-walled polycarbonate 1 with cut-outs or vestibules 2 arranged in such a configuration that a tortuous pathway 3 is created. The working fluid inlet and outlet 4 can be taken through the face of the panel or may be situated at the ends 5 by using modified conventional plumbing fittings. A thin covering layer 6 can be bonded over the vestibules, using a sealant or by heat sealing, in order to close them off. The ends of the interleave can be closed either by heat sealing the ends or by filling the interstices with sealant. Preferably, the interleave layer is used in a solar heat collector comprising a backing layer (8, fig.2) with a thermally reflective barrier (9, fig.2), an upper surface (11, fig.2) painted matt black to maximise absorption of solar heat, and a covering layer (6, fig.2) of multiwall polycarbonate.

Description

I
Invention TC 15 This invention relates to use of an interleave layer to aid manufacture and assembly of solar heatin2 panels.
(001) A thin-film solar heat collector panel is described in patent application No.0705357.2 (filed 21st March 2007). A panel is constructed from multiwall polycarbonate sheets and/or dark coloured self-skinned foam sheeting (or equivalent) bonded together to create a thin film of working fluid which passes through a tortuous pathway, collecting solar heat as it passes through the pathways. The entire structure is dependant on suitable sealants.
(002) This invention embodies an interleave layer as the centre element of a sandwich construction which is an independent sub-assembly of the solar heat collector.
(003) A particular advantage of this design is that the sub-assembly can be pressure tested separately before making up the panel and can be disassembled from it again should any fault develop, thus saving the cost of the outer layers which would otherwise have to be scrapped.
(004) The interleave layer is illustrated in Figure 1. A thin sheet of twin-wall polycarbonate or its equivalent (1) (available commercially as 4mm thick sheeting, or a similar size in other materials) has vestibules (2) cut in such a configuration that a tortuous pathway (3) is created. Inlet and outlet for the working fluid (4) can be taken through the face of the panel or the ends (5) as desired using modified conventional plumbing fittings, or specially constructed units. A thin covering layer (6) is bonded over the vestibules with suitable sealant or heat sealing in order to close the saidvestibules. The ends of the interleave (7) are closed either by heat sealing the ends or filling the interstices with sealant.
(005) The panel may be assembled as illustrated in figure 2. A backing layer (8), conveniently made of either multiwall polycarbonate sheet or self-skinned foam plastic has aluminium foil (or equivalent) (9) laid on it as a thermal reflective barrier.
The interleave layer (1) is laid on this. It's upper surface (II) may be painted mali black to maximise absorption of solar heat. A covering layer (6) of multiwall polycarbonate or equivalent completes the assembly. It is then fixed together by interference fit beading, conveniently using conventional UPVC double-glazing channel section or simple U' shaped channel, or an existing proprietory material.

Claims (4)

  1. * Claims 1 An interleave layer in a sandwich construction of a solar
    heat collector, with inlets in the lower face of the unit.
  2. 2 An interleave layer as claimed in claim 1 which is an independent sub-assembly of the collector panel
  3. 3 An interleave layer as claimed in claim 1 an array of vestibules cut through twinwall polycarbonate (or similar) sheeting designed to create a tortuous flow of working fluid through it, facilitating efficient heating of the fluid.
  4. 4 An interleave layer as claimed in claim 1 whereby inlets for the working fluid may be in the front face, or ends of the interleave S An interleave layer as claimed in claim 1 whereby the upper layer may cover the whole length of the lower panels
