Definitions

• the present invention relates to a solar collector unit with a flowing heat transport medium, a solar collector consisting of several such units, and a method of manufacturing them.
• Fig 1 is a cross-sectional view ( i.e. parallel to the eaves ) comprising among other things frame construction, insulating bottom, support and cover material.
• Fig 2 is the corresponding longitudinal sectional view (perpendicular to the eaves at normal erection on a roof of a house).
• Fig 3-4 show alternative embodiments of mechanical fastening device for frame structure.
• Fig 4 also is an embodiment of fastening of an absorber.
• Fig 5 is a perspective view of an embodiment of support for free hanging of cover, and its fitting in the frame.
• Fig 6 is a longitudinal sectional view of alternative embodiment of support for cover material.
• Fig 7 is a cross-sectional view of support according to fig 6.
• Fig 8 is a cross-sectional view of embodiment of support for cover material according to a second alternative.
• Fig 9 is a top plan view of collector elements connected to each other, with an embodiment of parallel connection of absorbers of the exemplified embodiment.
• the figures show the frame of the solar collector, composed of prefabricated frame members (1,2,3,4) of preferably wood, suitably pressure impregnated or otherwise rot-resistant treated, disposed in such a way that the solar collector out of a supplied prefabricated kit may be easily assembled preferably on the erection site.
• each collector unit need not itself form a complete casing, bat does so together with adjacent units, as will be discussed in more detail subsequently.
• Upper and lower frame members are made in full length along the solar collector comprising two or more collector units, which also simplifies and cheapens the construction.
• the solar collector is assembled to units by putting its frame members toge ther , preferably by us ing mechanical assembly devices, such as at least one furniture fitting (12) or one assembling bolt (33) per joint. Furthermore these joints are preferably provided with guiding details e.g. guid ing pegs and drill holes (13) or tenons and grooves (14) to improve the measure accuracy of the solar collector units and facilitate the assemblage.
• us ing mechanical assembly devices such as at least one furniture fitting (12) or one assembling bolt (33) per joint.
• these joints are preferably provided with guiding details e.g. guid ing pegs and drill holes (13) or tenons and grooves (14) to improve the measure accuracy of the solar collector units and facilitate the assemblage.
• the side frame members of the solar collector are provided with laths (6,7) whose edge sides also serve as support for the long, sides of the bottom plate as below. These laths admit rainwater etc. coming in under the roofing to pass freely under the solar collector without affecting it. Similarly condensation moisture is enabled to air out.
• the laths are also used for fixing the solar collector to the bedding, either this is an even roof like matched board, plywood or the like, or it is a transver se tile strip constuction, or other bedding of framework.
• the bottom plate Due to the fact that the bottom plate has high strength it may be completely self-supporting within each unit. If necessary it can be supported by extra bed laths for instance performed and installed like (8) in figure 1.
• the ends of the laths (9,10) protrude preferably outside the upper and/or lower member.
• the bottom plate of the solar collector consists solely of a special composite material in form of a plate (5) simultanously performing three functions i.e. mechanical bottom, diffusion barrier and insulation. It is composed of in turn a sealing layer against diffusion preferably aluminium foil, an insulating layer preferably cellular plastic, such as polyurethane or polyisocyanurate foam and furthermore one sealing layer preferably of aluminium foil
• bottom plates are already at prefabrication given the exact size and are at installation positioned in respective solar collector unit, abutting to all sides of the frame. In doing so they are supported along the edges of their long sides by the laths (6,7) which are joined to the outer long sides respective the partition member of the frame.
• the bottom plates are preferably positioned in the solar collector unit without any special fixing.
• a run of jointing sealing compound (25) e.g. silicone gum keeps the bottom plate (5) in its position and makes a seal between the frame members (1,2,3,4) and the bottom plate.
• the solar collector contains an absorber furnished with ducts (35) for a flowing heat transport medium.
• the absorber can be made of sheet materials usually of metals like copper or aluminium, possibly with a surface treatment giving properties suitable for this purpose.
• the absorber units of the solar collector (29) are usually connected parallel by connecting the two preferably horizontally placed header pipes (22 and 21) for inlet respective outlet of the heat transport medium in such a way that it runs along the whole of the upper and lower frame members of the solar collectors (3,4) and through the partition member of the frame (1,2). These frame members therefore have holes or slots in their upper an lower ends (30) to make it possible. to join the headers of the absorber units to each other.
• connection fi ttings or connection hoses are fitted.
• the absorber is fixed in the collector units solely in one point along its longitude preferably at its upper header or corresponding. This is preferably arranged by attaching a pendulum (23) and a pipe clip alternatively a clamp or correspondingly to the upper frame member (3).
• the heat transport medium is made to circulate by a drivin pump and by a temperature sensitive control to carry the collected heat away. In some cases self-circulation may be sufficient.
• the total absorber area is connected preferably diagonally.
• the inlet pipe (32) is connected to the bottom left and the outlet tube to the top right or arranged opposite hand. Then the inlet tube can be placed. preferably inside the collector in the lower part parallel to the lower header pipe. Special holes or slots (31) are made for this purpose in the partition frame members (2). This admits the two pipes to be installed at the same side of the collector, and a more favourable installation is obtained.
• the inlet pipe (32) is preferably connected by a U-shaped fitting (36) at the end of the lower header pipe (22), which in accordance with examples in figure 9 gives flow direction according to arrows from lower right corner to upper left. Due to the symmetrical design of the solar collector the connection points can be chosen at the installation.
• tranverse profiles (11) e.g. T-shaped profiles are fitted at a suitable distance, which at the installation on the site are positioned in prefabricated slots in the s ideframe s and which are preferably hanging freely within each solar collector unit.
• these are provived with grooves or slots, wherein screws can be fitted and in that way fix the cover material to the profiles.
• a third examplary embodiment is shown in fig 8.
• Transverse profiles (26) whose length is equal to the inner width of the solar collector units are fixed between the side frames (1,2) by making one or several drill holes (27) in the two units at each connection point and tenons (28) are put
• the cover material (17) preferably consists of plastic sheets possibly with insulating ducts. When using single plastic sheets these are fixed to the longitudinal partition walls by overlapping joints as shown in fig 1. Then the solar collector is preferably sealed between frame and cover material, and between two layers of cover material with elastic profiles. This is preferably done by using two continous C-shaped sealing strips (18) to seal both sides of the upside surfaces of the frame. Preferably these strips are fixed. to the frame at prefabrication with e.g. staples or to the cover material with glue or self adhesive tape.
