Definitions

  • the present invention concerns a solar heating unit including at least one absorber element with a hot part/side where a liquid is heated by sunrays, and with a cold part/side where a liquid is conducted to an inlet at the hot part/side, where the heated liquid is conducted to a container for storage or for direct or indirect use.
  • the invention concerns a solar heating unit including at least one absorber element with a hot part/side and a cold side/part.
  • the at least one absorber element of the solar heating unit may advantageously include a first side and a second side where said sides are interconnected, preferably via a number of walls, whereby at least the hot part/side of the absorber element appears with a number of elongated channels.
  • channels may extend throughout the length of the absorber element, but may also be broken channels that e.g. have a length of 20 cm followed by an area or a length without channels/channel walls, or with channels with another dimension.
  • the channels can be broken in their longitudinal direction in the same area across the width of the absorber element, but they may also be made such that a given overlap is provided between channel walls and/or the area without channel walls.
  • circulation may be produced in the liquid flowing in the channels which may entail a better heat transmission and thereby a better efficiency of the absorber element.
  • the term elongated channels is applied in a broad meaning, as these channels can be closed channels running in parallel, but may also be with broken walls between the channels, where these breaks can be arranged side by side or staggered in the flow direction of the liquid. In one embodiment, it may even be so that the channels are formed by punctiform joints. Finally, the said channels may be arranged such that the liquid flows a longer way than the direct way. This may be achieved by providing the channels in an oblique, and possibly in an oblique or straight and shifting direction.
  • the absorber element is made in the main of plate-shaped plastic, for example extruded or pultruded plastic.
  • the hot part/side as well and the cold part/side can be made as mentioned and therefore consist of a long shaped channel plate constituting the hot part/side and the cold part/side.
  • two channel plates may be used as well which are joined in a manifold at the front edge of the absorber element.
  • the cold part/side is constituted by a number of hoses or tubes and thus not consisting plate with elongated channels.
  • the absorber element may advantageously be made of polyethylene, polypropylene or polyurethane, or another suitable type of plastic which may be decomposed after use.
  • all or parts of the solar heating unit may be made of plastic which is fibre reinforced; by this is meant i.a. fibres of glass or carbon, but also various plant fibres or other suitable fibre types.
  • a solar heating unit according to the invention entirely or partly of other materials, including metal such as e.g. aluminium or stainless steel.
  • metal such as e.g. aluminium or stainless steel.
  • some parts can be made of one material, while other materials are advantageously made of another material.
  • the parts of the solar heating unit in selected areas of e.g. the absorber element can be made of a plastic material in which is admixed one or more materials with increased thermal conductivity. This may e.g. be the case with regard to the entire item, but may also be on selected areas of the item.
  • An item, as e.g. the absorber member, may therefore advantageously be provided with an increased thermal conductivity on the areas where solar energy is collected, corresponding to the hot part of the absorber element, while these additions do not serve any purpose on the cold back side of the absorber member.
  • the absorber element in the main is made of plate-shaped metal, where the absorber element is formed by to layers of metal sheets where at least one of these layers of metal sheeting is provided with corrugations forming a number of connections between the metal sheets. These corrugations thus constitute walls between the two layers of metal sheeting.
  • the metal sheets are joined longitudinally by the corrugations, and hereby elongated channels are formed and possibly broken elongated channels between the two layers.
  • the broken channels and/or channel walls may in principle be compared with broken lines arranged side by side, where the line is interrupted at the same position on the length of all lines, or where there is a given offset between the interruptions.
  • the absorber element is constituted by to layers of metal sheeting, where only one of the layers are of metal sheets, while the other layer e.g. may be constituted by a plastic sheet with corrugations or projections which together with an additional sheet form channels, preferably elongated channels between the two sheet layers.
  • the absorber element is made of two layers of plate-shaped metal, where the hot part/side of the absorber element is formed by one sheet, this sheet constituting the first side, a manifold at the front edge of the absorber element and further constituting the second side of the hot side/part of the absorber element, where corrugations and/or embossings are provided on at least the part of the metal sheet constituting the second side. It is thus possible to make an absorber element of one piece of sheet material.
  • an absorber element can be made with an insert with corrugations or embossings that are inserted between the two previously mentioned sheets, whereby this insert together with at least one of the sheets form channels for flowing liquid.
  • the insert can be made of plastic, metal or other suitable material, and in a preferred embodiment the insert is fixed to the sheet by bonding or welding. This variant is particularly preferable when the absorber element is made in one piece of sheeting as it may be expensive and provide further challenges to make embossings and/or corrugations in the same sheet which is also to be bent and constitute an absorber element without traversing joints.
  • An insert as mentioned can be with channels that are rectilinear, broken, convoluted, oblique, varying in cross-section or designed in other ways such that a liquid may flow through the absorber element.
  • it may be an insert with a wire-netting look, where this insert is fixed to the outer/first side and to the inner/second side on the absorber element.

Water that has given off heat back to the absorber element for re-heating is conducted through these tubes.
  • a profiled insert may advantageously be used between the outer/first side and the inner/second side of the absorber element by which channels for the flowing liquid are formed.
  • the required joints be they either between the first and the second side of he hot part/side of the absorber element, the first side and an insert, or in connection with mounting of end pieces, may be provided by using welding, soldering, gluing, pressing or other suitable method.
  • the absorber element may furthermore include a number of absorber channels in the form of copper tubes which advantageously may be provided with ribs extending along the side of the copper tubes, where ribs as well as copper tubes act as absorber means. At one or both ends of these copper tubes, advantageously there may be applied a manifold by which respective tubes - via manifold - are connected to the container and/or channels, respectively, in the cold part/side.
  • the channels in the absorber element may be provided with one or more projections and/or recesses causing that the channels appear with an uneven surface.
  • a kind of "disturbed” flow may hereby be achieved in the channels, whereby the liquid may absorb heat more easily, as in principle it is circulated while flowing in the channel.
  • it may be a kind of grooves in respective channels where there are either rectilinear or convoluted projections or recesses on whole or parts of the inner surface of the channel.
  • the solar heating unit may be provided with an integrated liquid container, where the cold part/side as well as the hot part/side of the absorber element are directly connected to the container. It is thus an integrated container, and the solar heating unit in this variant appears as one assembled unit to which only flow and return are to be connected.
  • a solution is simple and thus with advantages on some markets and under some other conditions where a simple and completely uncomplicated solution is desired.
  • no other elements are to be mounted, and therefore no connecting hoses or tubes are provided between the absorber element and the container as in the prior art solutions.
  • a greater efficiency is hereby achieved due to lesser heat loss, and at the same time, the total solar heating unit is less vulnerable to leaks and possible actions from outside.
  • a solar heating unit according to the invention may advantageously be adapted such that the liquid can be circulated with forced as well as natural circulation according to wish; however, the thermal conditions in the heated liquid makes natural circulation very advantageous since it does not require energy supplied to a pump.
  • the absorber element and the external surfaces of the container are each substantially made in one piece, constituting a jacket, where this jacket is at least covered by one or more insulating members that together form an insulating jacket which at least surrounds the surfaces on the cold part/side of the absorber element and on a possible integrated liquid container, as the insulating jacket is with a geometry corresponding to the absorber element and alternatively also corresponding to the external contour of the container.
  • insulating members may typically be foamed insulating material, e.g. PUR arranged surrounding the said elements, corresponding to the bottom of the absorber element, and along the periphery of the container.
  • a solar heating unit according to the invention may advantageously be made with wedge shape wherein the hot side of the absorber element e.g. has an inclination between 5 and 30° in relation to the cold side.
  • a solar heating unit according to the invention may also be used with or on a support.
  • an absorber element which according to the invention can be made of a shaped channelled plate with wedge-shape, a cutout of an insulating core is typically provided between the cold part/side and the hot part/side of an absorber element.
  • this insulating core typically made of a foamed plastic material, the desired shape of the absorber element is fixed.
  • the solar heating unit may at least consist of an absorber element and alternatively include a container where the absorber element and the container, which are interconnected, are closed with end profiles, where these end profiles close the ends on the absorber element as well on the container.
  • a solar heating unit according to the invention may advantageously include a protective jacket at least surrounding the surfaces at the cold part/side of the absorber element and on a possible integrated liquid container.
  • This protective jacket is the outermost surface on at least large parts of the solar heating unit, forming a stable and secure construction.
  • the protective jacket covers and protects the previously mentioned insulation provided on the cold part/side of the absorber element and on a possible container.
  • a solar heating unit may advantageously include a transmission plate arranged above and spaced apart from the hot part/side of the absorber element.
  • This transmission plate may be formed of glass, polycarbonate, acrylic or other suitable plastic, ensuring that the sunrays are conducted into a cavity between the transmission plate and the hot part/side of the absorber element from where the heat is absorbed by the circulating liquid.
  • This transmission plate may advantageously be provided with the previously mentioned protective jacket such that it further covers and protects the surface on the hot part/side of the absorber element against cooling, thus simultaneously acting as a transmission plate.
  • a transmission plate In order to attain the best effect of a transmission plate it has to be arranged at a given distance from the absorber element. This may be achieved in several ways, but in a preferred variant the transmission plate rests on at least part of the insulation surrounding the absorber element and a possible container. Moreover, between the transmission plate and the hot part/side of the absorber element, spacing means may be arranged for maintaining a given spacing between the hot part/side of the absorber element and the back side of the transmission plate. These spacing means may be fixed to the hot part/side of the absorber element as well as to the back side of the transmission plate.
  • an end profile may be adapted with one or more projecting parts, where these projecting parts when an end profile is mounted extend into the above mentioned insulating core by which the projecting part causes positioning of the end profile in the absorber element.
  • One variant of the invention may be provided with an absorber element with a distribution manifold such that the liquid conducted from the cold side/part to channels on the hot side/part of the absorber element may be distributed.
  • This manifold may advantageously be arranged at the pointed end of a wedge-shaped absorber element where the liquid turns, and may in its simplest form be a simple chamber at the front edge of the absorber element.
  • the liquid flowing along the cold side/part of the absorber element may freely be distributed to the channels on the hot side/part of the absorber element.
  • the manifold may in yet a variant be designed with a more specific conduction of liquid from e.g. one channel to four lesser channels for a better and easier heating of the liquid.
  • the solar heating unit may include an adapter piece by which two or more sections may be connected, each section consisting of a jacket with absorber element with insulating core and alternatively a container.
  • the parts of the solar heating unit exposed to the sunrays may advantageously be made of a plastic material which is black or with a surface which is technically black, while at the same time it is obvious that the used material should be resistant to ultraviolet light, at least for a given time.
  • Such a solar heating unit is simple to produce and may be produced in low- technological regions. Particularly by the variant with integrated container there is a very good insulating capacity as thermal bridges between the absorber element and the container are eliminated causing increased efficiency. It is mentioned above that a solar heating unit according to the invention may be arranged on a support. Such a support may advantageously be adapted with adjustable legs or other adjustable means by which the inclination of the absorber element or elements in the solar heating unit may be regulated.
  • the entire solar heating unit is made as a sandwich construction, beginning with the channel plates/absorber channels in which the liquid flows, and further including the insulating core, insulating jacket and protective jacket, all constituting layers that are joined to a finished sandwich construction.
  • a heating element may be arranged in a container, typically an electric heating element that may supplement the solar heat or be used for as a safeguard against frost in the circulated liquid.

  • the mentioned expansion tank may be a pressurised expansion tank which may be arranged under the absorber element and which via a pipe connection, e.g. a helical tube, is connected to the part of the unit in which liquid is flowing.
  • a pipe connection e.g. a helical tube
  • the said pipe connection may advantageously be with a volume substantially corresponding to the total liquid volume in the solar heating unit, which e.g. may be from about 3 to 15 litres.
  • the hot liquid does thus not get into the pressurised expansion tank which is typically equipped with a rubber diaphragm that does not very well resist the high temperatures attained by the liquid in connection with boiling arising in the unit.
  • great certainty is advantageously ensured against opening of a safety valve, thereby discharging liquid from the unit by a pressure reduction.
  • the fact that liquid is discharged from the system requires regular service of the unit, which the user does not gives much attention to in general. In other words, it is very common that such solar heating units are not very efficient due to the fact that a sufficient amount of water is not present in the system.
  • a unit according to the invention may thus be used with a minimum of inspection and at the same time fulfil the customer's demand for efficiency, regardless of situations that may arise when boiling occurs in the unit.
