Abstract:
An insulating vacuum panel comprising an insulating support member enclosed within a sealed, flexible polymeric envelope, the envelope comprising a polymeric barrier film which minimizes permeation of gas and liquid through the barrier film, the panel having an R value per inch of at least about 20 wherein the enclosed insulated vacuum panel is useful as insulation to maintain an essentially constant temperature in a closed structure, and a system for storing and transporting temperature-sensitive materials wherein the insulated vacuum panels are employed to provide and maintain a constant temperature in the system are described.
Abstract:
An insulation panel comprises a mineral fiber board having a density between 8 and 28 pounds per square foot, the fibers having no organic binder thereon, and between 5 and 40 percent by weight of particulate material packed in the interstices of the board, and a gas-tight envelope encapsulating the board, the envelope being evacuated to a vacuum between 10.sup.-4 Torr and 10 Torr.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Bauteils eines Kühl- und/oder Gefriergerätes, wobei das Bauteil mehrschichtig aufgebaut ist und dadurch hergestellt wird, dass wenigstens eine Schicht, vorzugsweise mehrere oder alle Schichten des Bauteils in eine Form eingebracht werden und im Anschluß daran aushärten, wobei die Schichten aus demselben Material oder aus unterschiedlichen Materialien bestehen.
Abstract:
A vacuum heat-insulating panel comprises outer wrapping material and core material. A getter is provided in the core material. The outer wrapping material is made by compounding wrapped material without aluminum foil on one side or both sides. The core material is made of an aggregate of glass fiber with uniform laminated structure, and the diameter of the glass fiber is 1-3 µm. A method for manufacturing the vacuum heat-insulating panel is also disclosed. Due to very high vacuum degree in the vacuum heat-insulating panel, the heat transferring speed is reduced. And, because of the outer wrapping material without aluminum foil layer, the edge thermal bridge effect is eliminated and the heat insulation effect is very good.
Abstract:
Vacuum heat insulator comprising a laminated core made of a plurality of sheets of inorganic fibers having 10 mu m or smaller in diameter and a certain composition including SiO2 as a main component, Al2O3, CaO, and MgO, a gas barrier enveloping member, and an absorbent. The vacuum heat insulator is characterized by having at least one groove formed therein after fabrication of the vacuum heat insulator. Further, the vacuum heat insulator is characterized by using inorganic fiber core of which a peak of distribution in fiber diameter lies between 1 mu m or smaller and 0.1 mu m or larger, and not containing binding material for binding the fiber material. Electronic apparatuses of the present invention use the vacuum heat insulator. With use of the vacuum heat insulator, electronic and electric apparatuses superior in energy saving and not to present uncomfortable feeling to the user can be provided.

Abstract:
A refrigerator includes a vacuum-insulated cabinet structure enclosing an insulating cavity and including an outer wrapper having a first side wall defining a perimeter, an outer frame portion defined radially inward of the perimeter, and an inner area surrounded and supported by the outer frame portion. The inner area initially defines a first planar level with at least a portion of the outer frame portion extending to a second planar level parallel to and spaced apart from the first planar level in an axially outward direction. The insulating cavity is sealed and has a vacuum drawn therefrom with the outer frame portion deformed such that the inner area is moved axially inward away from the second planar level under a force of the vacuum within the insulating cavity with at least the portion of the outer frame portion remaining at the second planar level.
