Description

"EVACUATED PANEL FOR THERMAL INSULATION OF A BODY HAVING NON-PLANAR SURFACES"
The present invention relates to an evacuated panel which enables the thermal insulation of a body having non-planar surfaces to be obtained.
Evacuated panels, and particularly those made with plastic materials, are being increasingly used in all the fields wherein thermal insulation at temperatures lower than about 100 °C is required. As examples of applications can be mentioned the walls of domestic and industrial refrigerators, of the drink dispensing machmes (wherein thermal insulation is required above all in order to separate the portion of the hot drinks, generally at about 70 °C, from that of the cold drinks) or of the containers for isothemial transportation, for instance of drugs or cold or frozen food. Further, applications of these panels in the building field or in the car industry are studied. As is it known, an evacuated panel is formed of an envelope' wherein a filling material is provided. The envelope has the function of preventing (or reducing as much as possible) the entrance of atmospheric gases into the panel, so as to maintain a vacuum level compatible with the degree of thermal insulation required by the application. To this purpose, the envelope is made with so-called "barrier" sheets, characterized by having a gas permeability being as low as possible, which can be formed of a single component but more frequently are multi-layers of different components. In the case of the multi-layers the barrier effect is conferred by one of the component layers, whereas the other layers generally have functions of mechanical support and protection of the barrier layer. The filling material mainly has the function of spacing apart the two opposite faces of the envelope when vacuum is created in the panel, further to other features which will be pointed out in the following. This material can be inorganic, such as silica powder, glass fibers, aerogels, diatomaceous earth, etc.; or organic, such as rigid foams of polyurethane or polystyrene, both in the form of boards and of powders. The filling material must be anyway porous or discontinuous, so that the porosities or the interstices can be evacuated. Since the permeation of traces of atmospheric gases inside the panel is practically unavoidable, these panels contain in most cases also one or more materials (generally referred to as getter materials) capable of sorbing these gases so as to maintain the pressure inside the panel at the desired values. Because of the rigidity of the materials they are made of, the known panels have generally a planar conformation, and therefore can be used for the insulation of substantially parallelepiped bodies having planar surfaces, but they are not suitable for bodies having curved surfaces, such as bath-heaters or the pipings used for oil transport in the arctic regions, or bodies which are provided with superficial depressions and relieves.
One of the methods used so far for realizing the thermal insulation of bodies having non-planar surfaces consists in connecting to each other several flat panels in the shape of bands, for example by sticking together the edges thereof by means of a glue, so as to obtain a composite structure which can be bent along the junction lines so as to adapt it to the shape of the body which has to be insulated. However, in this kind of structures made of planar panels connected to each other, heat transfers take place at the junctions, and therefore the quality of the heat insulation offered by such structures is scarce.
Patent application WO96/32605 in the name of the British company ICI describes evacuated rigid panels having a non-planar shape and a method for the manufacture thereof, which consists in making in the filling material, prior to the evacuating step, grooves arranged in the desired direction and having suitable width and depth. Subsequently, the filling material is inserted into an envelope and the assembly is subjected to the evacuating step, by means of which the panels bend along the grooves and take on the final, non-planar shape. Finally, the evacuated panel is sealed.
However, it has been observed that in the course of said evacuation the envelope adheres to the filling material and gets at least partially inserted into said grooves so that, when the evacuation is completed, the thickness of the panel is not regular in all the parts thereof, being lower at the bendmg lines with respect to the planar portions of the same panel. Consequently, also the thermal insulation properties are not uniform, but are reduced along these bending lines.
Another drawback of the known non-planar panels consists in the risk that the envelope, which is pressed inside the grooves, breaks thus enabling the passage of atmospheric gases towards the inside of the panel which compromises permanently the properties of thermal insulation of the panel itself.
A further drawback of the known non-planar panels consists in that their curving is made necessarily during the evacuating step, that is, during the process of manufacture of the panels. The accomplishment of said curving notably increases the volume occupied by the panels, whereas it would be convenient to carry it out at the time of the final application of the panel, so as to reduce the difficulties and the costs for transport and storage thereof.
Therefore, object of the present invention is providing an evacuated panel for thermal insulation of bodies having non-planar surfaces which is free from said drawbacks. Said object is achieved by an evacuated panel whose main features are specified in the first claim and other features are specified in the following claims.
An advantage of the evacuated panel according to the present invention consists in that, thanks to the particular structure of the filling material, it can be bent until it adheres to the walls of the body which is to be insulated, with no grooves in the filling material being necessary.
Another advantage of the evacuated panel according to the present invention consists in that, during the curving, the several creases which are formed on the internal side of the curve cannot, because of their small entity, cause a breaking of the envelope itself nor a resulting permeation of atmospheric gases towards' the inside of the panel.
Further, the evacuated panels according to the present invention are manufactured, stored and transported to the place of the final application in the flat form, and only subsequently they are curved so that they adhere to the body wliich has to be insulated. A further advantage of the evacuated panel according to the present invention consist in that it can be manufactured with various thickness values, by using a variable number of boards of filling material of a single kind.
Another advantage of the evacuated panel according to the present invention consists in that on the main faces thereof can be made, simply and without carrying out milling operations, one or more depressions complementary to the relieves possibly present on the surfaces of the body which has to be insulated.
Further advantages and features of the evacuated panel according to the present invention will be evident to those skilled in the art from the following detailed description of some embodiments thereof with reference to the accompanying drawings, wherein: - figure 1 shows a cross-sectional view of an evacuated panel according to a first embodiment of the present invention in the flat conformation thereof; - figure 2 shows a cross-sectional view of the evacuated panel of figure 1 in the curved conformation thereof, and - figure 3 shows a cross-sectional view of an evacuated panel according to a second embodiment of the present invention. With reference to figure 1, there is shown that the evacuated panel according to a first embodiment of the present invention comprises an envelope 1 of known kind, formed for example of two barrier sheets welded along their edges, and a plurality of thin boards 2 of a filling material, equal to each other and placed one above the other inside said envelope 1. The total thickness of the assembly of boards 2 corresponds to the desired panel thickness, provided with only one board of filling material in the panels known so far.
Said boards 2 are preferably made of an open cell polymeric material, and their thickness must be sufficiently low so as to enable the curving thereof. Depending on the polymeric material used, the thickness of the boards can vary between about 2 and 8 mm. It is preferred, as filling material, the use of boards of polyurethane foam having a thickness of about 4-6 mm. These thickness values can be achieved by cutting the boards usually employed for the manufacture of panels of the known kind horizontally, that is, parallely to their main faces. Alternatively, the thickness of said boards can be reduced by compression, according to a process known in the field.
With reference to figure 2, there is shown that the evacuated panel according to the present invention has been curved and placed over the lateral surface of a cylindrical body 3, so as to cover it. Curving the panel is possible thanks to the low thickness and to the resulting flexibility of the single boards 2 which it comprises. During the curving step, said boards 2 slide on each other, thus reaching a different final bending radius, and consequently their ends are not aligned any more. In order to favor the reciprocal sliding of the various boards 2, and therefore the panel curving, plastic sheets can be inserted between each pair of adj acent boards.
In figure 3 there is shown an evacuated panel according to a particular embodiment of the present invention, placed on the non-planar surface of a body 4. In the particular case here represented, said non-planar surface is a curved surface comprising for instance a relief 5. The evacuated panel is formed of an envelope 1 containing a plurality of boards 2 of filling material, in this case four. Carvings, having shape and size equal to those of relief 5 of said non-planar surface, have been made in two adjacent boards 2', one of which is next to the envelope 1. Because of the evacuation, the envelope is adherent to the outer surface of the filling material and therefore, at the carvings, to the surface of the internal board 2 which is not carved, hi this way one of the main faces of the panel has a depression 6 exactly complementary to said relief 5.
Obviously, the number of the carved boards 2' and the size of the carvings depend on the shape of the depression which is desired on one face of the panel. The panels according to the invention may contain one or more getter materials, that is materials suitable for chemically sorbing moisture and other atmospheric gases. Preferred is the use of systems of two or three getter materials, containing at least one moisture chemical sorber and at least one component selected among a transition metal oxide (having the main function of sorption of hydrogen, CO, and hydrocarbons) and an alloy based on barium and lithium (having the main function of nitrogen sorption). Various getter systems of this kind are sold by the applicant under the name COMBOGETTER , among which in particular systems containing a moisture sorber and powder of alloy based on barium and litlu'um, described in patent EP-B-769117; and getter systems containing a moisture sorber and a transition metal oxide, with the optional addition of powder of alloy based on barium and litlrium, described in patent application EP-A-757920.
