    Foldable heat reflector
    The present invention relates to a foldable heat reflector which comprises at least one reflective layer and at least one carrier layer and is designed such that it comprises at least two plate-shaped parts, which are connected together foldable via at least one hinge point.
    Heat reflectors and their use are known for example from DE 20 2004 017378 U1. A heat reflector is placed behind a radiator or between the wall and radiator to reflect heat and in particular infrared radiation that is emitted to the wall into the room. In this case, the radiated heat is reduced to penetrate into the masonry. As a result, the heat emitted by the radiator or infrared radiation can be used better and more efficiently. A room can thus be heated better and more efficiently. As a result, the heating costs can be reduced if necessary.
    According to the state of the art, heat reflectors are provided and used in plate form or as rollers.
    The heat reflectors are glued to the non-reflective side thanks to an adhesive to the wall, with the reflective side facing the radiator.
    Plates can be conveniently glued because of their flatness. The dimensions of the plates are usually 50 cm x 50 cm. Thus, if necessary, several plates must be laid / mounted behind a radiator. The transitions between the plates, especially if not done very carefully and accurately, reduce the efficiency of the heat reflection and possibly even represent thermal bridges. A clean, precise and precise work is therefore very important, on the one hand to achieve a full-surface bonding and on the other hand to avoid gaps and adhesive residues at the transitions. This can be very expensive to attach the heat reflector plates due to the precision required when working. Furthermore, the plates can preferably detach again at the transitions. For many transitions, therefore, after some time very often at least partially detached plates are observed. Larger sized panels are harder to handle and store or take up more storage space. In addition, plates with larger dimensions may need to be adjusted more frequently and to a greater extent in terms of their dimensions. For this, the plates must be cut to fit each. If appropriate, this can lead to a high outlay, for example when installing / applying a plurality of heat reflectors, in particular if different dimensions are required in each case.
    Rolls can reduce the number of transitions. This can simplify attachment. In the case of rolls, however, it is aggravating that rolls are more difficult to glue. The rolled goods deformed by the rolling up are subject to tension, so that the material is not easy to process. In fact, due to these stresses, rolled products still have a certain curvature after unrolling, which makes bonding difficult. This can therefore also lead to a high cost when attaching heat reflectors. In addition, due to the tension caused by the deformation during rolling up, rolled goods may be more strongly released from the wall. The roll product also has the disadvantage that storage space is used inefficiently due to the roll shape.
    There is therefore a need for a heat reflector that can be easily, quickly and conveniently mounted between the wall and radiator.
    This is made possible by a foldable heat reflector according to the invention. The subclaims describe further possible embodiments of a foldable heat reflector according to the invention.
    A foldable heat reflector according to the invention may in particular comprise, for example, at least one reflective layer and at least one carrier layer and be designed such that it comprises at least two plate-shaped parts which are connected to one another foldable via at least one hinge point. This can ensure that the heat reflector in unfolded state can form a flat / flat surface that can be glued quickly and easily. In addition, it can thus be achieved that the heat reflector in the folded state can be stored as compact and space-saving as possible. Tensions in the heat reflector, which can occur due to deformation during rolling, are thereby completely avoided. In addition, thanks to the possibility of compactly folding a 'foldable heat reflector according to the invention, for example, it is easily possible to handle and store foldable heat reflectors according to the invention with larger dimensions. The use of foldable heat reflectors according to the invention, which can easily have relatively large dimensions when unfolded, contributes to the fact that preferably a largely continuous attachment / installation of the heat reflector (s) is made possible. As a result, the number of transitions / gaps between the attached foldable heat reflectors according to the invention can be reduced, and in particular, for example, the heat reflection and the thermal insulation can be improved.
    A reflective layer may be at least one layer which reflects heat and in particular infrared radiation. A reflective layer may according to the invention preferably comprise, for example, at least one metal layer and / or metal foil and in particular at least one aluminum layer or at least one aluminum foil. A reflective layer may, for example, also comprise at least one metal-coated film and in particular at least one aluminum-coated film. In particular, a reflective layer may comprise, for example, at least one metal or aluminum coated polyethylene, polypropylene or PET film. A reflective layer may preferably also comprise, for example, at least one metal- or aluminum-coated biaxially oriented polypropylene film (BOPP film). Furthermore, a reflective layer may also comprise at least one metal-paper composite and in particular an aluminum paper composite or at least one aluminum kraft paper composite. As a result, the highest possible heat reflection (or the reflection of infrared rays) can be achieved.
    A carrier layer may be at least one layer which supports the reflective layer and improves the mechanical stability of the reflective layer. As a result, the stability / rigidity of the heat reflector can be increased and the gluing can be simplified if necessary.
    The carrier layer and the reflective layer can be connected to one another. The carrier layer and the reflective layer may preferably be connected to one another, for example by gluing.
    In addition, the carrier layer may also preferably comprise at least one layer of thermal insulation material. As a result, the reflection of heat or infrared rays and the thermal insulation of a wall, to which the heat reflector is glued, can optionally be improved.
    A carrier layer may in particular comprise, for example, at least one layer of a polymer material and / or at least one foam layer of a polymer material. This can optionally be achieved, for example, a good thermal insulation. A foam layer makes it possible, if appropriate, to achieve, for example, a particularly good heat reflection and / or thermal insulation.
    The polymer material may comprise, for example, at least one bio-based polymer, polyethylene, polyurethane, ethylene vinyl acetate (EVA), polystyrene, in particular an expanded polystyrene foam (EPS) or an extruded polystyrene foam (XPS) and / or copolymers or mixtures thereof.
    If desired, at least one expanded polystyrene foam with one or more additives, such as, for example, graphite, may also be used as the polymer material. As a result, it is optionally possible, for example, to achieve a further improved heat reflection and / or thermal insulation.
    A carrier layer may optionally comprise, for example, at least one layer of a material of renewable raw materials and in particular of an insulating material of renewable raw materials, such as wood or natural fibers, wood chips or wool.
    The thickness of the carrier layer may usually be, for example, between 0.1 mm and 50 mm, preferably between 0.2 mm and 30 mm, more preferably between 0.5 mm and 20 mm, more preferably between 1 mm and 15 mm, more preferably between 1.5 mm and 10 mm, more preferably between 1.75 mm and 5 mm, more preferably between 2 mm and 4 mm. A greater thickness of the carrier layer contributes, for example, to a better heat reflection and / or thermal insulation and / or to a higher mechanical stability or rigidity.
    A joint may be, for example, a point at which the thickness of at least one carrier layer and preferably all
    Carrier layers is reduced. A reduction of the thickness of the carrier material can be achieved, for example, by at least one kink, a cut, a fold line or a notch / groove. A notch / groove can be achieved, for example, by a stamping process. In addition, in at least one cut, the entire carrier layer can be severed, so that at the hinge point, where appropriate, only the reflective layer remains to connect at least two plate-shaped parts of a heat reflector together. Thereby, the foldable heat reflector according to the invention can be conveniently folded to allow easy storage. Furthermore, this results in the folding no stresses that lead to a permanent curvature of the heat reflector. Thus, the foldable heat reflector according to the invention can remain flat to allow easy and convenient bonding.
    A hinge point can be arranged, for example, vertically or horizontally.
    A hinge point may preferably be arranged, for example, parallel to an edge of the foldable heat deflector according to the invention. In addition, a hinge point may preferably extend, for example, along the entire length and / or width of the foldable heat reflector according to the invention. Optionally, for example, a foldable heat reflector according to the invention may comprise both horizontally and vertically arranged hinge points. As a result, the foldable heat compensator according to the invention can be folded even more conveniently to allow easy storage.
    In addition, a foldable heat reflector according to the invention may, for example, also comprise at least one predetermined breaking point. A joint point can for example also correspond to a predetermined breaking point. For example, a perforated parting line may represent a predetermined breaking point that may be obtained by perforation. As a result, if appropriate, at least one plate-shaped part of a foldable heat collector according to the invention can be conveniently separated from the rest of the foldable heat collector according to the invention in order to change the dimensions of the heat collector quickly and conveniently.
    In addition, a foldable heat reflector according to the invention may, for example, also comprise at least one predetermined breaking point that does not correspond to a hinge point. Such a predetermined breaking point, which does not correspond to any joint, may preferably be arranged, for example, vertically or horizontally. Such a predetermined breaking point, which does not correspond to a hinge point, may preferably, for example, parallel to a
    Be arranged edge of the foldable heat deflector according to the invention. In addition, such a predetermined breaking point, which corresponds to no joint, preferably, for example, along the entire length and / or width of the foldable heat reflector according to the invention extend. A foldable heat reflector according to the invention may optionally comprise, for example, both horizontally and vertically arranged predetermined breaking points. As a result, if appropriate, at least one plate-shaped part of a foldable heat collector according to the invention can be easily separated from the rest of the foldable heat collector according to the invention in order to adapt the dimensions of the heat collector quickly and conveniently.
    For example, a foldable heat reflector according to the invention may be more preferably at least five plate-shaped parts, more preferably at least six plate-shaped parts, more preferably at least seven plate-shaped parts, more preferably at least eight plate-shaped parts, more preferably at least nine plate-shaped parts, more preferably at least ten plate-shaped parts at least eleven plate-shaped parts, more preferably at least twelve plate-shaped parts, more preferably at least thirteen plate-shaped parts, more preferably at least fourteen plate-shaped parts, more preferably at least fifteen plate-shaped parts, more preferably at least sixteen plate-shaped parts, more preferably at least seventeen plate-shaped parts, more preferably at least eighteen plate-shaped parts, more preferably at least nineteen plate-shaped parts, more preferably at least twenty plate-shaped parts, we It prefers at least twenty-one plate-shaped parts, more preferably at least twenty-two plate-shaped parts, more preferably at least twenty-three plate-shaped parts, more preferably at least twenty-four plate-shaped parts, more preferably at least twenty-five plate-shaped parts, more preferably at least thirty plate-shaped parts, more preferably at least thirty-five plate-shaped parts preferably comprise at least forty plate-shaped parts.
    All plate-shaped parts may optionally have, for example, the same dimensions. In particular, all plate-shaped parts may for example have the same width. Alternatively, certain plate-shaped parts may also have different dimensions and in particular a different width. A plate-shaped part may preferably have, for example, a rectangular shape. The high flexibility with regard to the shape, the number and the dimensions of the plate-shaped parts contributes to the fact that preferably a largely continuous attachment / laying of the heat reflectors is made possible. As a result, the number of transitions / gaps between the attached foldable heat reflectors according to the invention can be reduced, and in particular, for example, the heat reflection and the thermal insulation can be improved.
    The number of hinge points (N-1) of a heat reflector according to the invention may preferably correspond, for example, to at least the number of plate-shaped parts (N) minus one.
    Each plate-shaped part may, for example, have a width between 10 mm and 500 mm, preferably between 50 mm and 300 mm, more preferably between 100 mm and 250 mm, more preferably between 125 mm and 150 mm.
    Each plate-shaped part may preferably, for example, have a length which corresponds to the width of the foldable heat reflector according to the invention.
    A great flexibility in the choice of the dimensions of the plate-shaped parts helps that preferably a largely continuous attachment / installation of the heat reflectors is made possible. This can reduce the number of transitions / gaps between the attached inventive foldable heat reflector and in particular, for example, the heat reflection and the thermal insulation can be improved.
    A foldable heat reflector according to the invention can, for example, have the unfolded state, preferably, for example, a rectangular shape. As a result, a foldable heat reflector according to the invention can be adapted as conveniently as possible to the shape of a radiator.
    In the unfolded state, for example, a foldable heat reflector according to the invention may have a length of 20 cm, preferably 30 cm, more preferably 50 cm, more preferably 100 cm, further preferably 200 cm, more preferably 250 cm, further preferably 300 cm, further preferably 400 cm, more preferably 500 cm, more preferably 600 cm, further preferably 700 cm, more preferably 800 cm, further preferably 900 cm, further preferably 1000 cm, further preferably 1100 cm, more preferably 1250 cm, further preferably 1500 cm.
    A foldable heat reflector according to the invention can, for example, when unfolded, have a width of 10 cm, preferably 15 cm, more preferably 20 cm, more preferably 25 cm, further preferred 30 cm, further preferred 40 cm, further preferred 50 cm, further preferred 60 cm, more preferably 70 cm, more preferably 75 cm, further preferably 80 cm, further preferred 90 cm, further preferred 100 cm, further preferred 110 cm, further preferred 125 cm, further preferred 130 cm, further preferred 140 cm, further preferred 150 cm, more preferably 160 cm, more preferably 175 cm, further preferably 180 cm, more preferably 190 cm, further preferably 200 cm, further preferably 250 cm, further preferably 300 cm.
    A foldable heat reflector according to the invention can, for example, in unfolded state in the dimensions 10 mx 0.5 m, 10 x 0.75 m, 10 x 0.25 m, 5 mx 0.5 m, 5 mx 0.25 m, 5 mx 0.75 m, 2.5 mx 0.5 m, 2.5 mx 0.25 m or 2.5 mx 0.75 m.
    Foldable heat reflectors according to the invention can easily have relatively large dimensions when unfolded. Larger dimensions and / or great flexibility in the choice of dimensions preferably contribute to the fact that a largely continuous attachment / installation of the heat reflectors is made possible. As a result, the number of transitions / gaps between the attached foldable heat reflectors according to the invention can be reduced, and in particular, for example, the heat reflection and the thermal insulation can be improved.
    A foldable heat reflector according to the invention may, for example, also comprise at least one additional adhesive layer, which may preferably be applied to the side facing away from the reflective layer. This adhesive layer can also be protected, for example, by a suitable release liner and / or release paper. As a result, the foldable heat reflector according to the invention can be attached very easily and conveniently. The release liner and / or the release paper are thereby removed only from the additional adhesive layer,
