Abstract:
A core of a vacuum insulation member and a vacuum insulation member using the same are disclosed. The core of a vacuum insulation member includes: a plurality of plates which are spaced apart from each other; and a support member supporting the plurality of plates between the plates.
Abstract:
The invention relates to a fixing system for an insulating pipe of a dual insulating pipe type used for feeding liquefied LNG or liquid nitrogen, comprising an inner pipe through which the material for feeding passes, insulating material surrounding the inner pipe, and an outer pipe for protecting the insulating material surrounding the inner pipe. The insulating pipe fixing system for inserting and fixing an insulating pipe according to the invention is characterized in that the body of the fixing system is provided with a vacuum area for insulation. Therefore, according to the invention, it is easy to connect and disconnect pipes and this invention can be widely applied to connections of dual insulating pipes. Since the inside of the body is provided with an insulating section, the inner pipe area which is not surrounded by the insulating material can be insulated, so that overall insulation effect can be maximized.
Abstract:
The invention relates to the determination of the gas pressure in an evacuated thermal insulating board (9) having an insulating core (1) covered by a film (2). The inventive device comprises an assembly, which is integrated between the insulating core and the covering film of the thermal insulating board and which has a body that acts as a heat sink (3) (Al, Co, Fe, ceramic), and the body's thermal conductivity and thermal capacity relative to volume are greater than those of the insulating core. Said assembly also comprises a test layer (4) (0.3 mm nonwoven fabric made of plastic and glass fibers), which is arranged between the heat sink and the covering film and has a defined thermal conductivity that changes according to the gas pressure inside the evacuated thermal insulating board. From the exterior, a sensor device is applied to or pressed against the test device, which is placed inside the evacuated thermal insulating board and which is covered by the covering film. Said sensor device comprises a body (5) (coppered steel 78 DEG C, thermoelement (6)) having a distinctly different temperature than that of the test device (heat sink) whereby creating a heat flux, which is influenced by the thermal conductivity of the test layer, said thermal conductivity varying according to the gas pressure inside the thermal insulating board, and the magnitude of this heat flux is metrologically determined. The heat sink (3) can be provided in the form of a bottom part of a container for a getter material.
Abstract:
An evacuated panel for thermal insulation of a body (3, 4) having non-planar surfaces provided with two main faces and comprising a flexible envelope (1), made with one or more barrier sheets, and a filling material formed of at least two boards (2; 2') of an open cell polymeric foamed, laying one over the other, each one having a thickness comprised between about 2 and 8 mm.
Abstract:

Abstract:
The invention relates to a coupling for vacuum-insulated conduits or hose pipes which are provided for guiding one or more cryogen media. The inventive coupling consists of a single-core or multi-core coupler plug (S). The cryogen medium/media is/are supplied or discharged to or from said plug by means of a single-core or multi-core supply line (7) or by means of several supply lines. The inventive coupling also comprises a coupler socket (D). A conduit pipe (8) of the coupler plug (S) is designed in the axial direction and in such a way that said conduit pipe can move in relation to the coupler plug. Said conduit pipe (8) extends over the parting plane and into the coupler socket (D) when the coupling is in the coupled state. According to the invention, the supply line/s (7) is/are laterally connected to the coupler plug (S) or can be connected thereto. The invention enables essentially shorter overall lengths of such couplings, in addition to a reduction of the weight thereof and better operation of said couplings. Moreover, the torque exerted on the fixing of the coupling half that faces the vehicle can be reduced.
