Description
Vacuum insulation panel, fixed, as well as an element for refrigerated furniture that contains, fixed, this vacuum insulating panel.
DESCRIPTION OF THE INVENTION Vacuum insulating panels are commonly used for thermal insulation. The known vacuum insulating panels are composed of a precompressed porous granulate, a porous pressed plate or a hard open cell foam as a substrate, which is wrapped with a gas impermeable film, the film being welded or bonded after the evacuated.
As the filling material of vacuum insulating panels, for example, precipitated and dried silica solids, gelatinous silica, volatile ash, organic-based open cell foams, such as open-cell polyurethane hard foam or polyurethane hard foam agglomerate in powder as described, for example, in DE 4 439 331 and DE 4 439 328. Such vacuum insulating panels are also already used in the production of refrigerated rooms, for example refrigerated cabinets or refrigerated containers, by inserting them between the outer housing and inside and foaming the interstitial space that remains between the outer and inner housing.
REF: 25144 However, the assembly of vacuum insulating panels in refrigerated cabinets causes problems. According to the current state of the art, they are glued on a plate, for example a metallic chassis, by means of an adhesive sheet on both sides. Subsequently, this combined plate can be further processed to a sandwich plate, for example a door for a refrigerated cabinet, the residual hollow space being conventionally foamed (FIG. 1). QJ] on page 1 we see a plate that inclines the spine of RJ (1), an inner reservoir (2), a printable adhesive receptacle (3), E * V (4) and an exterior paced (5).
This is necessary, on the one hand, a complicated process uítietapa, on the other hand the foam (less effective, from the point of view of the insulation technology, compared to the vacuum insulating panel), requires isolation volume. In addition, such provisions are only limitedly free of heat conducting bridges. These disadvantages can be avoided if the vacuum insulating panel is fixed with a polyurethane foam tape, which is applied in the form of liquid reactive mixture (preferably circulating) on the edge of the vacuum insulating panel, on the rigid cover layer or between two rigid cover layers. Therefore, the object of the present invention is a vacuum insulating panel fixed on a rigid plate, which is fixed on the rigid plate by a polyurethane foam applied in the form of a liquid reactive mixture (Figure 2). The vacuum insulating panel is fixed on the rigid plate, for example a metal plate or plastic plate of ABS or polystyrene, placing the vacuum insulating panel on the rigid plate and applying a liquid reactive foam mixture around the insulation panel. of polyurethane so that, in the foaming and hardening, the foam sticks both to the plate and also to the vacuum insulator panel and thus joining the vacuum insulator panel to the plate. With this, in a very simple way the vacuum insulating panel is anchored on the plate advantageously, rigidly and without heat conducting bridges. A metal chassis is preferably used as the rigid plate (FIG. 4). If necessary, the reactive foam mixture can also be applied first and then the vacuum insulating panel inserted into the still liquid reaction mixture. According to the claimed arrangement, a plate with an irregular surface can also be combined easily and economically, for example an evaporator plate of a refrigerating appliance or a profiled sheet with a vacuum insulating panel. According to the invention, the vacuum insulating panel can also be fixed between rigid plates in a sandwich-like construction (FIG. 3). For the vacuum insulator panel they are used, advantageously, open cell recycled rigid plates. By this, the accuracy of adjustment, dimensional stability and leveling of the vacuum insulating panel are ensured. As reactive mixtures of polyurethane foam for fixing the vacuum insulating panel on the rigid plates, all common reactive mixtures of polyurethane foam, such as those common in the construction of refrigerated furniture, can be used. Preferably one-component polyurethane foams are used, for example Assil® (Henkel firm). Another object of the invention is an element for refrigerated furniture, which contains a vacuum insulator panel fixed on a rigid plate with a liquid reactive mixture of polyurethane foam. Such items for refrigerated furniture according to the invention can be used as sides, bottoms or covers of refrigerated furniture. In addition, a vacuum insulating panel can also be fixed on an evaporator (FIG. 5). The following examples should clarify the invention in more detail, but without limiting its scope. Figures Figure 1: Arrangement according to the state of the art (PAV: vacuum insulator panel). Figure 2: Arrangement according to the invention in which the vacuum insulating panel is fixed on a rigid cover layer by surrounding bands of polyurethane foam (side view and plan view). Figure 3: Arrangement according to the -invention with a metal chassis as a rigid cover layer
(side view and plan view). Figure 4: Arrangement according to the invention in which the vacuum insulating panel is fixed between two rigid cover layers (side view). Figure 5: Arrangement according to the invention with refrigerant evaporator unit. EXAMPLES Example 1 Production of a vacuum insulating panel: An open cell PU hard foam plate with a bulk density of 60 kg / m 3, of dimensions 800 x 500 x 25 mm, is vacuum welded (0.5 mbar) in a sheet bag composed of a complex of 3 layers (polyester, aluminum, polyethylene). Is the vacuum insulation panel produced having a thermal conductivity? of 10 W. Example 2 Vacuum insulator panel fixed on a metal chassis: On a metal chassis of dimensions 600 x 800 mm with a grooved contour of 30 mm (see figure 3) a central insulating panel is fitted centrally in the middle. vacuum of dimensions 540 x 740 x 20 mm. The surrounding 30 mm wide slit is filled with one component polyurethane foam. With this, the vacuum insulating panel is rigidly anchored and free of heat conducting bridges. Example 3 Vacuum insulator panel fixed on an aluminum plate: On an aluminum plate of dimensions 400 x 500 x 0.5 mm, 5 mm hard aluminum tubes arranged in the form of a coil are welded. On the face of the sheet to which the tubes are welded, a reactive mixture of polyurethane composed of 100 parts by weight (PP) of a polyether coinitiated by glycerol-sucrose, of OH 400, 2 PP of water, is spread. 10 PP of cyclopentane, 2 PP of dimethylcyclohexylamine, 100 PP of MD polymer. During the foaming process, a vacuum insulating panel of the same dimensions as the aluminum plate is placed on the reactive foam mixture. After hardening the foam, it has rigidly joined the plate loaded with the aluminum tubes with the vacuum insulator panel. It is noted that, in relation to this date, the best method known to the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention. Having described the invention as above, property is claimed as contained in the following:
