Description
Vacuum insulating panel
[0001 ] The present invention relates to a vacuum insulating panel (VIP) and a method for manufacturing vacuum insulating panels.
[0002] Vacuum insulating panels are commonly used for thermal insulation, notably for refrigeration systems such as refrigerators or refrigerated transport containers. They may also be used for building insulation, especially when low thermal conductivity in combination with small thickness is desired.
[0003] Vacuum insulating panels usually consist of a core material retained within a sealed envelope. Conventionally, the panel cores are inserted into prefabricated bags and subsequently evacuated and sealed along the open side. One or more sealing flaps of the finished panel project from end and/or side faces; these sealing flaps are folded against the panel and fixed with adhesive tape. The sealing flaps at end and/or side faces of the vacuum insulation panels the flaps may interfere with sealing of the panel into an opening and/or contribute to undesired thermal conduction at the panel edges. US 201 1/0129637 discloses a method for manufacturing vacuum insulating panels in which sealing flaps are folded towards each other at a major surface of the panel.
[0004] One aim of the present invention is to provide a construction of vacuum insulating panel which is simple and inexpensive to manufacture whilst providing low thermal conductivity. [0005] According to one of its aspects, the present invention provides a vacuum insulating panel as defined in claim 1. Additional aspects are defined in other independent claims. The dependent claims define preferred and/or alternative embodiments.
[0006] Folding of the sealing flaps in the same direction facilitates manufacture of the panel, notably high speed manufacture; for example by allowing, in some configurations, a single roller moving in a single direction or moving in a continuous path to sequentially fold each of the sealing flaps. Folding of the sealing flaps in the same direction also facilitates installation of the vacuum insulating panels in a frame or support, notably when installation comprises sliding the vacuum insulating panel into a support; in this case, the vacuum insulating panel is preferably slid into its support from a leading edge of the vacuum insulating panel which is substantially parallel to the length of the sealing flaps to a trailing edge of the vacuum insulating panel with the sealing flaps configured such that they are folded in a direction from the leading edge towards the trailing edge of the of the vacuum insulating panel. In this way, the vacuum insulating panel may be slid in to position with minimal risk of snagging of the sealing flaps thus increasing assembly efficiency and productivity. The vacuum insulating panel may be secured in a frame or support, for example a wall of a refrigerator, using a foam or adhesive, for example a polyurethane foam, which is injected on the assembly line. A further advantage of folding the sealing flaps in the same direction, notably folding the sealing flaps in a direction from a leading edge towards a trailing edge of the vacuum insulating panel, is to facilitate flow of foam or adhesive injected in a direction from the leading edge towards the trailing edge in a way that minimises obstruction to flow caused by the sealing flaps. This is particularly useful to facilitate the flow of a mixture of for example
isocynate and polyol to encapsulate the vacuum insulation panel completely before polymerization to polyurethane (PU) takes place with the vacuum insulation panel being positioned in such way that the flow of the reacting mixture is not obstructed by the sealing flaps [0007] The core of the vacuum insulating panel may comprise a mineral fibre insulating material for example comprising mineral wool, glass wool, rock wool or combinations thereof. Preferably, the fibre insulating material comprises glass fibres.
[0008] The fibres of the core may be bound together, notably at intersections between fibres, for example by means of a binder, preferably an inorganic binder and/or by treatment with an acid, notably a dilute acid, for example sulphuric acid or nitric acid. Such acid treatment may create fusion points between individual fibres. The vacuum insulating panel may have a density which is < 250 kg/m3 , preferably < 200 kg/m3, more preferably < 180 kg/m3 and/or which is≥ 50 kg/m3, preferably≥ 100 kg/m3, more preferably≥ 120 kg/m3.
[0009] The vacuum insulating panel may have a substantially parallelepiped shape. It may have:
- a length which is≥ 10 cm,≥ 20 cm or≥ 30 cm and/or which is < 120 cm, < 100cm or < 80 cm; and/or
- a width which is≥ 10 cm,≥ 20 cm or≥ 30 and/or which is < 100 cm, < 80 cm or < 60 cm; and/or
- a thickness which is≥ 0.5 cm,≥ 1 or≥ 1.5 and/or which is < 5 cm, < 4 cm or < 3 cm.
[0010] The vacuum insulating panel may have a thermal conductivity of < 10 mW/m-K, preferably less < 8 mW/m-K, more preferably < 6 mW/m-K. The level of vacuum in the vacuum insulating panel may be < 3 mbar, < 2 mbar, < 1 .5 mbar, < 1 mbar, < 0.5 mbar or < 0.1 mbar. [001 1 ] The first and/or second film sections may have a thickness >100pm, preferably ≥50μπΊ, more preferably >20pm.
[0012] The first and/or second film section may comprise a plurality of stacked layers, for example comprising an adhesive layer, a barrier layer notably a metal barrier layer, and/or a surface protection layer, notably in this sequence. The adhesive layer may provide a layer facing the core of the panel; the surface protection layer may provide an exposed layer at the external side of the panel. The adhesive layer on one film may provide a layer adapted to be thermally welded to the other film, for example by heat sealing, notably to provide a seal and maintain a vacuum.
[0013] The surface layer may comprise a structure in which a polyethylene terephthalate (PET) film and a nylon film are stacked. The PET film may have a thickness between 5 and 20μηΊ, preferably from 10 to 15pm; the surface layer may have a thickness of between 15 m to 50pm, preferably from 20 to 30μιτι. The surface layer may comprise a strengthening vinyl resin which may be applied to an upper side of a PET film, and the vinyl resin may include polyvinyl chloride (PVC), polyvinyl acetate (PVA), polyvinyl alcohol (PVAL), polyvinyl butyric (or PVB), polyvinylidene chloride (PVDC) or combinations thereof.
[0014] A metal barrier layer of the film section may comprise aluminium (Al) foil. The metal barrier layer may have a thickness of between 5 and 10pm, preferably from 6 to 7pm; it may serve to block gas permeation through the film and/or protect the core material.
[0015] An adhesive layer of the film section may comprise at least one plastic film selected from polyethylene (PE), high-density polyethylene (HOPE), low-density polyethylene (LDPE). linear low-density polyethylene (LLDPE), polypropylene (PP), cast polypropylene (CPP), oriented polypropylene (OPP), polyvinylidene chloride (PVDC), polyvinyl chloride (PVC), ethylene vinyl acetate (EVA) copolymer, and ethylene vinyl alcohol (EVOH) copolymer films. The adhesive layer may have a thickness of at least 1 m, at least 20pm, at least 50pm; at least 75μιη or at least 95pm.
[0016] The surface protection layer, the metal barrier layer, and the adhesive layer of the cover material may be bonded to each other, notably by a polyurethane resin.
[0017] The vacuum insulating panel may comprise a getter, notably enclosed inside the vacuum insulating panel, comprising one or more materials capable of absorbing moisture and/or absorbing one or more gasses. The getter serves to help maintain the degree of vacuum in the vacuum insulation panel. The getter may comprise calcium oxide, preferably calcium oxide powder notably having a purity of at least 90 % packed in a pouch; the pouch may be formed of nonwoven fabric which may be impregnated with crepe paper and polypropylene (PP). A quantity of ≥ 10g and/or < 50 g of calcium oxide is generally appropriate. The getter may have a moisture absorptivity of at least 20%, preferably at least 25%.
[0018] In one embodiment, the first film portion of the envelope is wrapped around the core leaving an uncovered portion at one major surface, notable at a central portion of one major surface. The second film portion, suitably dimensioned, may be arranged at this previously uncovered portion and the adjacent peripheries of the first and second film portions assembled together to form flaps projecting away from the core which are subsequently sealed. Alternatively, the second film portion may be arranged at the panel core and the first film portion subsequently wrapped around the core. The same dimension of the first film portion may be used for different dimensions of vacuum insulating panels with different dimensions for the second film portion. A tautly fitting envelope may be achieved by pulling adjacent peripheries of the first and second films towards each other prior to sealing the flaps. The second film portion may be stretched over a forming chute for connection with the first film portion.
[0019] An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawing of which:
Fig 1 is a schematic end view of a vacuum insulation panel before sealing in which the flaps are folded in the same direction.
[0020] Fig. 1 shows an embodiment of a vacuum insulation panel 10 comprising a core 1 1 enclosed by an envelope which consists of a first 21 and second 41 film section. In practice the envelope lies tightly against the surface of the core 1 1 but is illustrated in an exploded view for clarity.
[0021 ] The core 1 1 of the vacuum insulating panel is produced by:
- mixing loose glass wool fibres in a dilute sulphuric acid solution to produce a slurry;
- transferring the slurry on to a perforated conveyor belt;
- removing moisture from the slurry through the conveyor belt, notably via gravity and applied suction, and further drying the fibres remaining from the slurry, notably by passage through a drying oven;
- cutting to desired length and width dimensions. [0022] The envelope around the core 1 1 is produced by:
- arranging a first film section 21 around the core so that it entirely covers one major surface 31 of the core, covers the two side faces 32, 33 of the core and covers peripheral sections
34, 35 of the other major surface 36 of the core;
- arranging a second film section 41 at the central portion of the other major surface 36 of the core which is not covered by the first film section 21 such that, at each of the two portions at the other major surface 36 where the first 21 and second 41 film sections meet, a flap 51 , 52 is formed from contact between the undersides of peripheral portions of the first and second film sections;
- sealing the first and second film sections together along each of the flaps.
[0023] The first and second film sections 21 , 41 are a laminate comprising a top layer of a 12 pm polyvinylidene chloride (PVDC)/polyethylene terephthalate (PET) film, a 25 pm nylon film, a 6 pm aluminium foil, and, as a lower layer facing the core material a 50 pm low- density polyethylene (LDPE) film.
[0024] Base sections of the first 21 and second 41 films which form the flaps are pulled together under tension prior to heat sealing of the flaps to facilitate tight fitting of the envelope against the surface of the core. Fig 1 illustrates the flaps 51 , 52 being folded in the same direction so that they lie flat against the major surface 36. Once folded against the major surface, the flaps 51 , 52 are held in place by welding, adhesive or adhesive tape.
[0025] Subsequently, a first end (not shown) of the envelope is sealed, air is evacuated from the core and the second end 62 is sealed to provide the vacuum insulating panel. Folding of the flaps 51 , 52 against the major surface 36 may be carried out prior to or subsequent to evacuation of the panel.
[0026] The absence of flaps at the side faces 32, 33 facilities close abutment of adjacent panels and/or cooperation of the side faces 32, 33 with a housing.
