Description

  • The invention relates to a solar collector according to the preamble of claim 1.
  • A solar collector or solar collector is a device through which a transmission medium flows, which absorbs the energy that is introduced by incident sunlight in the solar collector. By this energy, the transmission medium heats up so that it can be used in particular for the heating of buildings, service water, etc. For example, the transmission medium is heating water which circulates in the heating circuit of a building.
  • In the field of such solar panels, it is known to form these in the form of a housing in which a pipe system is located, through which a transmission medium such as water flows. The front of the housing is permeable to sunlight, so that the medium in the underlying pipe system can be heated by solar energy. The pipe system and the housing can be used for different applications, in which z. B. water to be heated, take various forms. Furthermore, various additives such as reflectors and / or absorbers can be provided to increase the efficiency of the solar collector.
  • For example, in flat solar panels directly behind the pipe system, an absorber plate may be provided which absorbs the solar radiation as well as possible and converts it into heat. At the same time, the absorber plate should emit as little heat as possible in the form of radiation to the environment. The back and side portions of the absorber plate are therefore preferably insulated within the housing with thermal insulation against the release of heat in these directions.
  • In the forms of such absorber plates, it is particularly known to form them wavy. Through this waveform, several ridges or ridges are formed, on which the pipes of the pipe system can be placed. The absorber plate then rests with the undersides of the grooves formed thereby on a rear heat insulation.
  • For example, the European patent publication EP 2 058 604 B1 a solar collector with such a wave-shaped absorber plate which is bounded on the sides and the back of a heat insulation. Also the British patent application GB 2 037 873 A disclosed in the embodiment of 3 a solar collector with a pipe system on a wave-shaped plate and lateral and rear thermal insulation, wherein the plate is designed as a reflector. The same applies to the wave-shaped aluminum plate inside a solar collector, which comes from the patent US 4,237,870 is known. To protect such absorber or reflector plates against the release of heat to the rear and to the side, several relatively thick heat insulation is often provided in these areas, which increases the dimensions of the associated housing for the solar collector. This also increases the weight of the solar panels, which is particularly disadvantageous when mounting the solar collector on the roof of a building.
  • Based on this prior art, it is therefore an object of the invention to provide an improved solar collector with wave-shaped reflector plate, for the least possible insulating material is required.
  • According to the invention, this object is achieved by a solar collector according to independent claim 1. Advantageous developments of the solar collector resulting from the dependent claims 2-13.
  • It should be noted that the features listed individually in the claims can be combined with each other in any technically meaningful manner and show further embodiments of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.
  • The solar collector according to the invention comprises a housing with a solar radiation permeable front cover and at least one side wall, wherein within the housing behind the front cover a reflector plate and behind the reflector plate, a rear thermal insulation are arranged. Between the front cover and the reflector plate, a pipe system is further arranged, in which a heat transfer medium flows. In this case, the reflector plate is wavy running with multiple ridges and intervening grooves, which are each connected by a flank. Thus, the reflector plate forms a plurality of grooves, which are interconnected by raised ridges or ridges, and the pipe system is positioned on these ridges of the reflector plate.
  • The reflector plate reflects the incident sunlight toward the pipe system so that the heat transfer medium in the pipes of the pipe system is heated. For this purpose, at least the pipe system side facing the reflector plate is preferably made shiny.
  • According to the invention, at least one lateral end region of the reflector plate, which adjoins the at least one side wall of the housing, protrudes beyond the combs of the reflector plate in the direction of the front cover. The upper edge of this end portion is thus higher than the ridges of the reflector plate, ie closer to the front cover than the ridges of the reflector plate. As a result, the reflector plate forms, for example, two lateral wings, which preferably run parallel to the ridges of the reflector plate.
  • By these extended end portions, the reflector plate forms a kind of shell with corrugated bottom, so that at least on the sides with the extended end portions, the delivery of heat to the environment and in particular to the adjacent side walls is reduced. In one embodiment of the invention, the surfaces of these extended end portions are not designed to be shiny, but have a coloring and / or coating, which equips the reflector plate in these edge regions as possible with high absorption and low emission levels. For this purpose, the end regions can be dyed black, for example. The laterally extended end portions of the reflector plate thus form a side insulation.
  • The inventive design of the reflector plate can be dispensed with in the region of the extended end portions on a lateral heat insulation. In one embodiment of the invention, therefore, no heat insulation is arranged on the at least one side wall, on which the at least one lateral end region of the reflector plate is located. As a result, in turn, reduce the dimensions and weight of the solar collector, and the entire structure of the solar collector is simplified. This also facilitates the assembly of the solar collector in the production. In particular, however, a longer pipe system can be accommodated in the housing even with the same dimensions of the housing, which increases the available heat exchange surface in the solar collector. Furthermore, a reduced amount of insulating material in the manufacture of the solar collector leads to reduced amounts of material to be disposed of when the solar collector is fed to disposal / recycling after its use. However, it can also be provided that the laterally extended end portion of the reflector plate is used according to the invention in addition to a side insulation to support them.
  • In a preferred embodiment of the invention, the lateral end region is formed by the extension of an edge of the reflector plate. The wave-shaped reflector plate thus does not end with the lowest point of one of its outer grooves, but from this lowest point extends a last edge in the direction of the front cover to beyond the last outer ridge out. In this case, viewed in the direction of the front cover, the lateral end region can also protrude beyond the pipe system which is located on this last comb. Basically, an extended end portion is advantageous, which shields the adjacent side wall as large as possible. The lateral end portion contacts the at least one sidewall to which it abuts, but preferably not to permit heat conduction between the reflector plate and the sidewall. An adjacent side wall in the sense of this invention therefore does not necessarily mean that the reflector plate bears against the side wall, but the respective end region lies only in the side region of the housing. The front cover also preferably does not touch the lateral end region.
  • On the back, however, a thermal insulation is provided to prevent in particular the direct contact between the reflector plate and the back of the housing. This rear thermal insulation may consist in particular of melamine resin foam or a foam with comparable properties. In one embodiment of the invention, the rear thermal insulation not only serves as the insulation, but can also be used to hold the reflector plate within the housing. In particular, a movement of the reflector plate in the direction of the side walls of the housing, in which the extended end portions are, should be prevented so as to avoid contact between the reflector plate and these side walls. In conventional solar panels lateral heat insulation is provided, where the reflector plate can rest. In the absence of such lateral heat insulation, however, it is necessary to fix the reflector plate within the housing suitable. For this purpose, the rear thermal insulation is advantageously used. For example, this can be clamped within the housing and the reflector plate in turn fixed on the thus fixed thermal insulation. In a further embodiment, it can be provided that the thermal insulation extends at least partially between the reflector plate and a rear side of the housing and into a region between the reflector plate and at least one side wall of the housing. The heat insulation is thus not only at the back of the housing, but partially protrudes into the area between the reflector plate and side wall. However, she does not protrude so far into the side area that they would be considered as additional side insulation, which completely covers the side wall. It just sticks up so far on the side that the heat insulation between the side wall and the reflector plate can be clamped.
  • In one embodiment of the invention, the thermal insulation is formed by at least two insulation strips. It is thus not a continuous plate of the insulation material, but several stripes. As a result, can be achieved for the rear thermal insulation material savings. For example, the insulation strips run parallel to the alignment of the combs of the reflector plate. The reflector plate can then rest with the undersides of their grooves on a plurality of insulation strips, so that the reflector plate has no direct contact with the back of the housing of the solar collector. However, it does not have a strip under each gutter be attached, but two side stripes and, for example, a strip under a central groove are also sufficient for the desired effect.
  • In an alternative embodiment of the invention, however, the insulation strips are transverse to the orientation of the combs of the reflector plate. For example, they may be at an angle of about 90 ° to the crests. The undersides of the grooves of the reflector plate are so on several insulation strips at the same time, with two lateral and one central insulation strips would be sufficient here.
  • In order to hold the reflector plate within the housing, the ends of the insulation strips may be angled slightly upwards so that they can be clamped between the reflector plate and a side wall. In parallel to the crests of the reflector plate extending insulation strip, the reflector plate is then prevented by the clamping action of a movement in this direction. However, the reflector plate is not clamped between the two side walls, which should not touch their extended end portions, but in a rectangular housing between the other two side walls. So that the reflector plate can not also slip transversely to the insulation strip of the rear insulation, the clamping is preferably so strong that this movement is prevented.
  • Further advantages, features and expedient developments of the invention will become apparent from the dependent claims and the following description of preferred embodiments with reference to the drawings.
  • From the pictures shows:
  • 1 a schematic cross section through a first embodiment of a solar collector according to the invention;
  • 2 a further cross section through a solar collector according to the 1 ;
  • 3 a schematic plan view of a solar collector according to the 1 ;
  • 4 a schematic cross section through a second embodiment of a solar collector according to the invention;
  • 5 a further cross section through a solar collector according to the 4 ; and
  • 6 a schematic plan view of a solar collector according to the 4 ,
  • Of the 1 is a schematic cross section through a first embodiment of a solar collector according to the invention 10 refer to. This is a section through the example, rectangular or cuboid housing, the reflector plate located therein 20 , a pipe system located on it 21 and a rear heat insulation of the solar collector 10 , The housing of the solar collector 10 is essentially a front cover 11 , a back 16 and at least one sidewall formed. In a rectangular solar collector, for example, four side walls are provided, of which in 1 two opposite side walls with the reference numerals 12 and 13 Marked are.
  • The reflector plate 20 is wavy, with this form several raised ridges and intervening grooves are formed. Two crests are in 1 by way of example with the reference numbers 25 and 26 while one between these combs 25 . 26 lying gutter with the reference number 24 is marked. The two crests 25 . 26 and the gutter are over sloping flanks 27 and 29 connected with each other. The combs can be pointed, rounded or flattened, as is the embodiment of the 1 provides. Also concave combs are possible, which adhere to the contour of the pipes of the pipe system 21 let adjust.
  • On the combs 25 . 26 the reflector plate 20 is the serpentine pipe system 21 arranged in which a heat transfer medium such as water flows. The front cover 11 is sun-translucent, for example, designed as glass, so that solar radiation through the front cover 11 on the preferably shiny surface of the reflector plate 20 can fall. This reflects the radiation on the pipe system 21 , whereby the heat transfer medium flowing therein heats up. The pipes of the pipe system 21 may consist of copper, while the reflector plate 20 also made of copper or may preferably be formed of aluminum. The reflector plate 20 can also be referred to as an aluminum insert.
  • On the back of the reflector plate 20 are several insulation strips 30 ... 38 attached on which the reflector plate 20 with the bottoms of their gutters 24 rests. In the embodiment of 1 is provided under each groove an insulation strip, but for example, could the stripes 30 . 34 and 38 also sufficient to achieve the desired effect, namely that the reflector plate 20 no direct contact to the back 16 of the housing has.
  • In the embodiment of the 1 are two lateral end areas 22 and 23 the reflector plate 20 provided, which in the direction of the front cover 11 seen over the ridges of the reflector plate 20 stick out. These lateral end regions are formed in particular by two outer, extended flanks. The reflector plate 20 thus does not end with a flank, which rests with its edge on an insulating strip, but by a second flank, a further groove is formed, the second flank is longer than that of the last comb of the reflector plate 20 enough. Preferably, these two extended flanks protrude 22 . 23 almost completely into the corners, which through the front cover 11 and the side walls 12 and 13 be formed. The reflector plate 20 but has no contact with these components of the housing.
  • Preferably, the end regions end 22 . 23 the reflector plate 20 about 2-5 mm in front of the case. The reflector plate 20 itself, for example, has a material thickness of 80-500 μm, preferably of about 120 μm. The height of the entire structure of heat insulation and reflector plate 20 is for example between 20-50 mm, in particular between 25-40 mm. The thickness of the rear thermal insulation and thus the insulation strip 30 ... 38 is on the order of about 10 mm, and the material thickness of the housing and in particular the rear wall 16 is at least 2 mm, preferably at least 3 mm.
  • So that the reflector plate 20 can not move within the housing and thereby still touch the side walls, at least one insulation strip is designed so that it the reflector plate 20 inside the case. This is from the further schematic cross section of 2 can be seen, which is a section along the line AA in 1 represents. On the cut insulation strip 36 lies the wave-shaped reflector plate 20 with the underside of one of their gutters. In the area of the side walls 14 and 15 who are now in 2 can be seen, the insulation stretches 36 to the area between the reflector plate 20 and these side walls 14 . 15 into it. The isolation strip 36 this is done slightly angled upwards so that the reflector plate 20 can not move in the direction of their crests anymore. To prevent a movement across the crests, is the insulation strip 36 according firmly between the reflector plate 20 and the side walls 15 and 16 trapped. So can the reflector plate 20 not even between the side walls 12 and 13 move, which is easily ensured that the lateral end portions 22 and 23 the reflector plate 20 these sidewalls 12 . 13 do not touch, but the set distance is maintained. Also a movement in the direction of the front cover 11 can be prevented this way.
  • The isolation strip 36 Although in the area between the reflector plate 20 and the side walls 14 . 15 also further up towards the front cover 11 stick out to the side walls 14 and 15 to completely insulate, but a minimum length for the clamping action would also be sufficient. Furthermore, all or only some of the insulation strips used can be designed for this clamping action. In particular, two lateral insulation strips 30 and 38 with clamping action would possibly for a fixation of the reflector plate 20 be sufficient inside the housing.
  • 3 shows this first embodiment of a solar collector 10 in a schematic plan view, wherein the serpentine running pipe system 21 it can be seen that a feed 40 and a process 41 for the heat transfer medium flowing therein. The cross section of the 1 corresponds to a section along the line BB in 3 , However, the number of routed lines is reduced for ease of illustration and more turns are usually used. The pipe system 21 is located above the wave-shaped reflector plate 20 with several combs 25 . 26 and intervening channels 24 , of which again only the gutter example 24 between the crests 25 and 26 which is on the insulation strip 37 rests. While the reflector plate 20 not up to the side walls 14 and 15 protrudes, all insulation strips extend 30 ... 38 below the reflector plate 20 up to these side walls 14 . 15 and can be trapped between them. We already mentioned, but only single insulation strips 30 . 34 and 38 be designed for a clamping action.
  • On the other two side walls 12 and 13 are the top edges of the two extended end portions 22 and 23 the reflector plate 20 to recognize. These also do not protrude to the side walls 12 . 13 but end shortly before this.
  • Of the 4 is a schematic cross section through a second embodiment of a solar collector according to the invention 10 ' can be seen, with the insulation strips across the crests 25 . 26 or gutters 24 the reflector plate 20 run. The remaining features correspond to the embodiment of the 1 - 3 , There is an insulation strip 30 shown cut. To the reflector plate 20 to keep within the housing, this and other insulation strips can be made slightly angled upwards at the ends. Due to the sloping flanks through which the extended end portions 22 and 23 are formed, the clamping action in the direction of the side walls 12 and 13 but limited. Therefore, two outer insulation strips are preferably designed to be the reflector plate 20 between the other two side walls 14 and 15 can pinch. This is in the cross section of 5 shown a section along the line AA in 4 represents. The ends of the two outer insulation strips 31 and 32 formed angled so that the reflector plate 20 between the side walls 14 and 15 is trapped. Again, the clamping is carried out according to so that thereby also a movement of the reflector plate 20 between the side walls 12 and 13 is prevented, so that the extended end portions 22 and 23 the reflector plate 20 not the side walls 12 . 13 and / or the front cover 11 can touch.
