摘要:
An insulating panel and shapes each having an outer, continuous membrane, an internal rigid frame, and an enclosed vacuum space. The outer continuous membrane is made up of a top membrane and a bottom membrane each having a plurality of biaxially curved, concave surface which are loaded in tension when the top or bottom membranes are exposed to ambient atmospheric pressure. Between each biaxially curved, concave surface is an arcuate path through which differential tension loadings on the adjacent biaxially curved, concave surfaces are offset, thereby reducing the structure requirements on the internal rigid frame. A second embodiment has an expansion joint means, the top or bottom membrane which enable the panel to maintain the tension stress loadings on the top and bottom surfaces when thermal contraction or expansion occurs in the top or bottom membranes, a corner shape, an inside corner shape, and a container embodiment are also disclosed herein.
摘要:
A refrigeration appliance having a vacuum insulation system wherein a combination of vacuum thermal insulating panels and polyurethane foam provide the thermal insulating properties as well as structural support. The panels are to be spaced apart from one another with a space between the cabinet and appliance liner so that the foam will lock the panels in place. Also the panels are to be spaced from the corners of the cabinet to permit the foam to flow into the corners. The panels can be applied directly to the cabinet or they can be spaced between the cabinet and liner, held by spacers. In either case, an adhesive is used to hold the liners in position prior to introduction of the foam.
摘要:
The present invention relates to a composite core material for a vacuum insulation panel which exhibits excellent initial insulation and long-term durability, a method of manufacturing the same, and a vacuum insulation panel using the same. The vacuum insulation panel includes a composite core material formed of glass fiber wool and a glass fiber board, and an outer skin material having a layered structure comprising a surface protective layer, a metal barrier layer, and a bonding layer from the outside to vacuum-package the core material.

摘要:
The present invention relates to a core material for a vacuum insulation panel that is formed with a phenolic resin, a vacuum insulation panel using the core material, and a method for manufacturing the vacuum insulation panel. More particularly, the core material is formed with a cured phenolic resin foam having a closed cell content of 20% or less. The cured phenolic resin foam includes cells whose average diameter is adjusted to 50 to 500 µm. The cells have fine holes with an average diameter of 0.5 to 30 µm on the surfaces thereof to allow the cured phenolic resin foam to have a void content of at least 50%. The use of the cured phenolic resin foam ensures high thermal insulation performance and improved structural strength of the core material, and enables the production of the core material at reduced cost.
摘要:
The present invention relates to a vacuum insulation panel (1) comprising a core material (2) with open porous structure and a barrier (3) that holds the core material (2) together. The open porous core material (2) is filled into a barrier (3) preferably together with a getter material, depending on the material properties forming the core material (2) and vacuumed. Thus, a vacuum insulation panel (1) is realized comprising the open porous core material (2) having low thermal conductivity coefficient, with increased insulation effectiveness.

The present invention provides a thermal insulation panel (10) having two outer concaved layers (14, 16) and an inner tension (24) member formed by two substantially parallel panels (26,28). The peripheries of the layers and panels are secured to a thermal barrier (22) extending around the periphery of the panel (10) and a vacuum seal (25) seals the edge. In operation, a partial vacuum is created within the panel which causes concaved layers (14, 16) to flatten and tension panels (26, 28) to be placed under tension. This tensional loading creates a strong and rigid structure without the need for internal supports which can create thermal inefficiency.

Die Erfindung betrifft ein Vakuumdämmelement (10) aus einer mit einer ersten Umhüllung (18) gasdicht umhüllten inneren Füllkammer (12) und einer zweiten, äußeren gasdichten Umhüllung (28) die eine oder zwei äußere Füllkammern (32) ausbildet. Die innere Füllkammer (12) enthält ein grobporöses oder grob strukturiertes Dämmmaterial (14), Wasserstoffgas und ein mit Gettermaterial gefülltes Heizelement (16) zur Absorption und Desorption von Wasserstoff und weist eine schaltbare Wärmeleitfähigkeit auf.
摘要:
The present invention relates to a core material for a vacuum insulation panel and a method of manufacturing the same. The method includes (a) preparing a solution of an inorganic binder; (b) dipping glass wool into the inorganic binder solution; (c) loading the glass wool on an upper portion of a chamber; (d) creating a vacuum in the chamber to discharge the inorganic binder solution from the glass wool into the chamber; and (e) drying and molding the glass wool into the form of a core material for manufacturing a vacuum insulation panel, thereby enhancing long term-durability of the vacuum insulation panel.
摘要:
A vacuum insulation panel (1) improves heat transfer performance while improving durability of a core material (10) and a manufacturing method thereof. The vacuum insulation panel includes a gas-interception sheathing (12) material to cover a core material (10). The interior of the sheathing material is decompressed so that the sheathing material is hermetically sealed. The core material is formed of a lump of fiber, and the fiber has a hollow part formed therein.
