Definitions

  • the invention according to a first aspect thereof relates to an insulation wall panel comprising a central layer with one or several mutually adjoining insulation panels, each insulation panel having a panel surface on either side and a circumferential edge, wherein the central layer is provided at each of its mutually opposing sides with a core layer of insulation plates that has a circumferential edge.
  • a "circumferential edge" in the present document is understood to be an edge that extends between the two surfaces located at the two mutually opposing sides of a panel or plate across the thickness of the respective panel or plate.
  • the insulation panels and insulation plates may differ from one another, but alternatively they may be (substantially) identical. The reason for the distinguishing use of the two terms is merely one of clarification, so as to make a distinction between the central layer and the core layers.
  • insulation in the present document denotes thermal insulation.
  • Such an insulation wall panel is known and is used, for example, in domestic freezer cabinets. Because of its high insulation value, the insulation panel used herein is a VIP (Vacuum Insulation Panel), i.e. a panel filled with insulating material and subsequently evacuated.
  • the known insulation wall panel or VIP is coated with a synthetic resin foam, which does have an additional insulating effect, but is mainly designed for preventing damage to the VIP panel, or at least reducing the risk thereof. Indeed, if the wall of a VIP panel is pierced, the vacuum will be lifted and a major portion of the insulating effect will be lost forever.
  • the known insulation panel's application possibilities are limited because of its vulnerability.
  • an alternative insulation panel other than a VIP may be used, for example one made of synthetic resin foam.
  • the insulation value may be comparatively low, but the consequences of damage are less serious than with a VIP panel.
  • Insulation walls panels are also known from the documents US 3,573,144 , US 2004/0031794 A1 and JP 2009 019089 A , the latter disclosing an insulation wall panel according to the preamble of claim 1.
  • the present invention aims to improve an insulation wall panel as described in the introduction such that it has wider application possibilities, especially as a construction panel.
  • the present invention provides an insulation wall panel as described in the introduction, wherein each core layer is provided with a skin layer at its side facing away from the central layer, wherein a reinforcement layer is provided between the central layer and each of the adjoining core layers, wherein at least a reinforcement rib extends around the circumferential edge of the or each insulation panel between the two reinforcement layers, and wherein at least a reinforcement rib extends around the circumferential edge of one or more insulation plates between a reinforcement layer and the adjoining skin layer.
  • the interconnection of the reinforcement layers and ribs gives the wall a structure such that it has a monolithic character.
  • the two skin layers are protective layers that shield the core layers, which may be easily penetrable, against the introduction into these core layers of objects that come into contact with the insulation wall panel.
  • the skin layer may comprise a plastic or a composite material.
  • the skin layer could comprise a metal for the purpose of reinforcement, but such an insulation wall panel would provide a less satisfactory insulation than one with a plastic.
  • the reinforcement layers and reinforcement ribs provide the insulation wall panel with a high bending stiffness.
  • the construction of the insulation wall panel according to the present invention as described above provides an improvement in the mechanical and thermal insulation characteristics as compared with those of the known insulation wall panel described further above.
  • the reinforcement layers and ribs but also the skin layers positioned at a distance to one another contribute to the required bending stiffness of the panel. The degree to which they contribute thereto depends inter alia on the material from which these skin plates are manufactured. An increase in the stiffness of these skin plates directly increases also the bending stiffness of the panel. If the skin plates are constructed from fibre-reinforced plastic, the bending stiffness can be increased in a direction in which the greatest flexural stresses will occur by choosing a suitable fibre orientation. The fibre reinforcement can be optimally utilized in this manner.
  • the central layer comprises one or several Vacuum Insulation Panels, denoted VIP panels hereinafter.
  • VIP panels are known for their comparatively high insulation value when used as insulation panels.
  • VIP panels have a comparatively high stiffness since they are panels having filled vacuum chambers.
  • the VIP panels preferably have a rectangular circumferential edge. The panels can then be readily positioned next to one another, while substantially constant interspacings can be realized.
  • a core layer comprises insulation plates having a rectangular circumferential edge. Again, it is advantageous that the insulation plates can be provided next to one another with constant interspacings.
  • reinforcement ribs are provided between the reinforcement layers in a staggered arrangement with respect to reinforcement ribs provided between a reinforcement layer and a skin layer.
  • the mutual staggering of the relevant ribs provides a comparatively long cold bridge between the two skin layers as compared with reinforcement ribs that lie aligned with one another and bridge a comparatively short distance between the two skin layers.
  • a reinforcement rib between the reinforcement layers extends substantially in the centre of an insulation plate and/or that a reinforcement rib between a reinforcement layer and a skin layer extends substantially in the centre of an insulation panel. A maximum length of a cold bridge between the two skin layers is obtained in this manner at all times.
  • a core layer comprises insulation plates made of a foam material.
  • Foam material for example plastic foam, is a comparatively inexpensive insulation material. If the central layer already gives the insulation wall panel a high insulation value, it may suffice to provide a comparatively inexpensive core layer of lower insulation value.
  • a core layer may comprise high-grade insulation plates, for example in the form of VIP insulation plates.
  • the core layer may alternatively comprise insulation plates of a solid material. This may contribute to a high stiffness of an insulation wall panel.
  • a reinforcement layer is a fibre reinforced plastic layer.
  • a fibre reinforced plastic layer can be generated in a simple manner in an insulation wall panel according to the present invention, as will be described further below in the present document. Given a correct choice of plastic and fibres, a core layer can be created in this manner which provides the insulation wall with a very high stiffness.
  • a very stiff core layer can be obtained after curing of synthetic resin when the fibre reinforced plastic layer comprises mats, fabrics and/or patterns of fibres.
  • fibres in the form of mats, fabrics and/or patterns can be applied in a simple manner and to a defined thickness.
  • the fibres of the fibre reinforced plastic layer comprise glass fibres, carbon fibres and/or aramid fibres. These types of fibres enhance the stiffness of the plastic layer.
  • the reinforcement ribs comprise a plastic.
  • the reinforcement ribs may be provided in the form of separate elements between the reinforcement layers, or they may alternatively be integral with the reinforcement layers, for example in that plastic is injected by a method to be discussed further below. If the reinforcement ribs comprise a fibre reinforced plastic, this will contribute to the stiffness of the insulation wall panel.
  • Connecting the reinforcement ribs integrally to one or both of the reinforcement layers prevents the ribs from shifting relative to the reinforcement layers, thus providing an additional stiffness against shearing.
  • the reinforcement ribs comprise a reinforcement element made of a solid material, an excellent stiffness will be obtained between two mutually adjoining reinforcement layers.
  • the present invention relates to the use of an insulation wall panel according to the first aspect of the invention as a wall of a container, in particular a sea container.
  • Sea containers for cooled transport also denoted reefers
  • An insulating material for example PUR foam
  • a specific problem that manifests itself in reefers is a delamination of the core layer. This is caused by the considerable forces to which the containers are exposed.
  • the containers are arranged in high stacks on board a ship.
  • varying and strong forces are exerted on the containers, inter alia owing to the motion of the travelling vessel, which forces are greater in proportion as a container is lower down in a stacked column.
  • the insulation value of an insulation wall is severely diminished by this delamination.
  • the present invention aims to provide a wall for use in a reefer container which has at least the insulation value of a known reefer container and which eliminates, or at least reduces to a large extent, the problem of delamination caused by said major shear forces.
  • This object is achieved by the use of an insulation wall panel according to the first aspect of the invention as a wall for a reefer container.
  • the reinforcement ribs of an insulation wall according to the present invention provide a mechanically strong connection and thus generate a higher shear resistance between the skin plates.
  • the reinforcement ribs provide an additional stiffness against shearing because they limit the relative shearing deformations of the layers interconnected by the respective reinforcement ribs.
  • reinforcement ribs are integrally joined to one or both of the reinforcement layers, it is prevented that the ribs can shift relative to the reinforcement layers, thus providing an additional stiffness that counteracts shearing.
  • a thermally well insulated container wall with a good resistance to shearing is thus provided thereby.
  • a container constructed in this manner especially if at least one layer, for example the central layer, comprises insulation panels or plates with a high insulation value, for example VIP panels or plates, will have a thermal insulation that is at least as good as that of the known reefer container wall.
  • the present invention relates to a thermally insulated sea container comprising an upper wall, a lower wall, a front wall, a rear wall, and two side walls.
  • Such containers are known as so-termed reefers.
  • a rear wall of a known reefer is provided with doors that give access to the container.
  • a reefer may comprise its own cooling device at the front wall or it may be connected to an external cooling device.
  • a cooling device may be accommodated in a frame that covers the entire front wall.
  • the walls of known reefers are insulated by means of sandwiched constructions so as to minimize unnecessary energy consumption. This sandwiched construction in the known reefers consists of two thin metal outer skins and a core of thermally insulating foam in between.
  • the present invention aims to provide a reefer that is better insulated against heat transfer than known reefers.
  • This is achieved by the present invention in that at least the side walls comprise an insulation wall panel according to the first aspect of the present invention.
  • Such a sea container or reefer is thermally very well insulated.
  • the upper and/or lower wall of the reefer preferably also comprise such an insulation wall panel.
  • the front and/or rear wall comprise such an insulation wall panel which may constitute a complete wall or which may be provided as a hinging door panel for providing access to the container.
  • a fibre reinforced reinforcement layer has a thickness lying in a range of between 0.5 and 3.0 mm.
  • a fibre reinforced reinforcement rib has a thickness lying in a range of between 0.5 and 3.0 mm.
  • a core layer comprises strips of plastic foam having a thickness lying in a range of between 10 and 30 mm.
  • a core layer comprises strips of VIP panels having a thickness lying in a range of between 10 and 25 mm.
  • the present invention relates to a method of manufacturing an insulation wall panel according to the first aspect of the present invention, which method comprises the following steps:
  • the method according to the present invention for manufacturing an insulation wall panel is based on a vacuum injection technology under foil, which is known to those skilled in the art.
  • dry reinforcement materials and dry core layers are placed in an airtight planar mould.
  • the entire assembly is then covered with an airtight foil, an underpressure is generated under the foil, and synthetic resin is injected under the foil.
  • the synthetic resin is cured and a fibre reinforced plastic panel has been created.
  • the manufacture of an insulation wall panel with the staggered reinforcement ribs as described above is achieved in that the panels and plates of mutually adjoining layers are provided in a staggered arrangement relative to one another each time.
  • the method of manufacturing an insulation wall panel is a time-consuming method because an insulation wall panel cannot be taken from the mould until the synthetic resin has been completely cured.
  • the curing time is several hours for an insulation wall panel that is to be used as a reefer wall panel.
  • the provision of the fibres is steps d), f) and/or h) is effected in that in the respective preceding step an insulation plate or panel, as applicable, surrounded by a fibre mat is provided, whereby the number of steps is reduced and a reinforcement layer and/or reinforcement rib of a defined thickness can be realised in a simple manner.
  • a VIP panel is provided as the insulation wall panel or insulation plate.
  • a first step is to place the reinforcement layers of the first skin plate in the mould.
  • the first core layer comprising PUR foam is realized in that strips of PUR foam are first enveloped all around in a fibre mat and then placed on top of a possibly first fibre layer for reinforcement of the first skin plate.
  • This layer is then covered with a fibre layer which will form a reinforced layer later between the first core layer and a central layer that is to be subsequently provided.
  • the VIP panels which are again in the form of strips, preferably enveloped in fibres, and which are to form the central layer, are placed strip by strip on the stack realized thus far.
  • the dimensions of the strips of said PUR foam layers and of the VIP panels are such that the lateral edges thereof, which constitute the partition walls owing to their envelopment in reinforcement layers, are in a staggered arrangement relative to one another.
  • a fresh fibre layer is applied, whereupon the second core layer of PUR foam is provided, which may again be similarly constructed from layers of PUR foam enveloped all around in fibre layers.
  • the assembly may be covered with a fibre layer that is to form the other skin layer of the insulation wall panel.
  • the assembly of "dry" components in the mould is then ready for being injected with synthetic resin by the method of vacuum injection under foil referred to above.
  • FIG. 1 is a diagrammatic front elevation of an insulation wall panel 1 according to the present invention constructed as a reefer container wall.
  • the side wall 1 in this example has a length of 5700 mm and a height of 2400 mm.
  • full lines drawn in the container wall 1 indicate vacuum insulation panels (VIP panels) present inside the container wall 1.
  • VIP panels 2 In vertical direction there are two VIP panels 2 each time. It is prevented thereby that any damage to the container wall 1, causing a leak in a VIP panel 2, will render a column leaky over the full height of the container wall 1, whereby its insulation value would be considerably impaired.
  • the VIP panels are each sandwiched between two PUR plates lying on either side of the relevant VIP panel 2.
  • the VIP panels 2 and the PUR plates 3 are of equal width but they are arranged such that a plate always covers two panels over half the width thereof, and vice versa.
  • the PUR plates 3 extend over the full height of the container wall 1. This is because a local spot of damage in a PUR plate 3 has no impact on the insulation value in a different region of this PUR plate 3, in contrast to a VIP panel 2. It is not visible in figure 1 that the VIP panels 2 and the PUR plates 3 are mutually separated each time by a fibre reinforced plastic. This will be explained in more detail with reference to figure 2 .
  • FIG. 2 is a diagrammatic cross-sectional view of an insulation wall panel 11 according to the present invention.
  • the insulation wall panel 11 is built up from a number of layers which will be described below in their order from top to bottom.
  • the layer of the insulation wall panel 11 shown as uppermost in figure 2 is a skin layer 12 manufactured from a cured gel coating. Below this there is a protective layer 13 of glass fibre reinforced plastic.
  • the next layer is a core layer 14 manufactured from polyurethane (PUR) plates 25 lying next to one another and mutually separated by reinforcement ribs 21 manufactured from glass fibre reinforced plastic.
  • Below the core layer 14 there is a next reinforcement layer 15, also manufactured from glass fibre reinforced plastic.
  • a reinforcement layer 17 of glass fibre reinforced plastic lies below the central layer 16.
  • a next core layer 18 manufactured from polyurethane (PUR) plates 27 lying next to one another and mutually separated by reinforcement ribs 23.
  • a reinforcement layer 19 manufactured from glass fibre reinforced plastic.
  • the bottom layer finally, is a skin layer 20 which is again manufactured from a cured gel coating.
  • the PUR plates 25, 27 on the one hand and the VIP panels 26 on the other are not stacked such that the plates 25, 27 and panels 26 overlap by their halves each time.
  • These reinforcement layers 14, 16, 18 and ribs 21, 22, 23, give the insulation wall panel an improved shear resistance.
  • the reinforcement ribs 21, 22, 23 together with the reinforcement layers 15, 17 form a cold bridge because the reinforcement ribs 21, 22, 23 and layers 15, 17 are interconnected.
  • the cold bridge is lengthened by the sum of the horizontal distances between the relevant ribs 21, 22, and 22, 23, respectively (actually the horizontal distance between the ribs 21 and 23).
  • This lengthening of the cold bridge owing to the staggered positions of the reinforcement ribs 21, 22, 23 results in comparatively little thermal leakage being caused by this cold bridge.
  • the cold bridges are longest in a container wall 11 as shown in figure 1 , where the PUR plate 3 and the VIP panels 2 always overlap by half.
  • the cold bridges are shortest in a situation in which the reinforcement ribs 21, 22, 23 are mutually aligned and in fact form a direct connection between the reinforcement layer 13 and the reinforcement layer 19.
  • the VIP panels 2 are of the same width as the PUR plates 3. However, the VIP panels 2 and the PUR plates 3 may be of different widths.
  • Figure 3 diagrammatically shows the construction of an insulation wall panel according to the present invention suitable for serving as a wall of a reefer container, wherein the various layers are diagrammatically indicated with (thickness) ratios that need not necessarily correspond to the actual (thickness) ratios.
  • a first mould part 31 is provided into which a 350 ⁇ m thick gel coating layer 32 of an isolphthalic acid polyester is introduced. This layer is to form the outer side of the insulation wall panel and may be provided with a pigment.
  • the gel coating 32 forms an uninterrupted whole and will form one of the outer walls of the insulation wall panel, comparable to a skin layer in figure 2 , after the insulation wall panel has been manufactured.
  • CSM chopped strand mat
  • First core layer portions are deposited on this stack.
  • These first core layer portions comprises PUR foam strips 34, corresponding to PUR plates in figure 2 , with a thickness of 20 mm and a density of 35 kg/m 3 , enveloped all around in a layer of 150 g/m 2 of CFM 33.
  • VIP panels 35 for the central layer are subsequently placed hereon, also enveloped all around in a layer of 150 g/m 2 of CFM 33.
  • the VIP panels 35 are 15 mm thick and have a density of 200 kg/m 3 . Since the surfaces of the PUR foam strips 34 mentioned above and of the VIP panels 35 are both coated with the 150 g/m 2 CFM 33, the thin, reinforced plastic intermediate layer is automatically created thereby after an injection with synthetic resin. As was the case with the previous layer, the fibre reinforced synthetic resin partition walls are again created in that the edges of the VIP panels 35 are coated with 150 g/m 2 CFM 33 and the packed panels are laid tightly against one another.
  • Second core layer portions are provided on this package. These core layer portions are also formed by PUR foam strips 34 with a thickness of 20 mm and a density of 35 kg/m 3 , enveloped all around in a layer of 150 g/m 2 CFM 33.
  • the assembly is finally covered with two layers of unidirectional (UD) glass fibre patterns 32c of 800 g/m 2 each and also 1x CFM 32b of 150 g/m 2 .

  • the layers may alternatively be provided in the form of smaller mats, patterns or sheets.
  • the PUR foam strips 34 and the VIP panels 35 may be covered by a glass fibre mat also at their end faces, if so desired.
  • a filled mould closed on all sides is obtained in this manner.
  • a synthetic resin is subsequently injected into the mould through the inlet opening. If necessary, a recess is provided in the adjoining skin layer 32 at the level of the inlet opening.
  • the assembly is evacuated (to approximately 0.5 bar underpressure) and injected by a standard injection method with a standard orthophthalic acid polyester resin. After curing, the product is unmoulded, the foil and the peelply fabric are removed, and the edges are trimmed.
  • the synthetic resin penetrates into the free spaces and in between the fibres of the glass fibre mats 32, 33. Once the mould has been completely filled, there is a waiting period until the synthetic resin has been cured into a plastic, whereupon the mould parts 31, 36 can be separated.
  • An insulation wall panel according to the present invention has thus been created, suitable for use as an insulating wall panel of a reefer and capable of absorbing the concomitant forces without the risk, or at least with a very small risk, of delamination through shea
  • the description of the figures mentions specific materials for the various layers and ribs each time.
  • the present invention is obviously not limited to these materials.
  • Glass fibres may be replaced with alternative fibres such as carbon fibres, aramid fibres or the like.
  • An insulation material other than PUR may be used for the insulation plates.
  • Alternative, preferably comparatively strongly insulating insulation plates may be used instead of VIP panels.
  • the reinforcement ribs and reinforcement layers are integrally connected to one another and made from the same material in figure 2 , and so they are implicitly also in an insulation wall panel manufactured by a method according to figure 3 .
