Abstract:
A modular, aerogel-based vacuum insulated pipe section (10) comprising an outer conduit (12); an inner conduit (22) concentrically disposed within the outer conduit (12) with aerogel insulation (30) and a condensable gas being disposed in the insulation space (20) between the concentric conduits (12, 22). As a stand-alone pipe section (10), the insulation space (20) is at a pressure within the range of from about 100 microns Hg to about 1000 microns Hg. However, in operation, when a cryogenic fluid is traversing the inner conduit (22), the condensable gas condenses and the pressure within the insulation space (20) is further reduced to range of from about 1 microns Hg to about 5 microns Hg. The vacuum insulated pipe section (10) further includes a coupling arrangement disposed on a first end (52) of the inner conduit (22) and a second end (54) of the inner conduit (22), the coupling arrangement configured to engage or mate with a corresponding end of another modular vacuum insulated pipe section.
Abstract:
An appliance includes an outer wrapper, an inner liner, a trim breaker having a channel that receives at least one of a wrapper edge of the outer wrapper and a liner edge of the inner liner, and a composite encapsulation system that hermetically seals an insulating cavity defined between the outer wrapper and the inner liner. The composite encapsulation system includes a base adhesive and an outer adhesive, wherein the base adhesive defines a structural adhesive component and the outer adhesive defines a sealing adhesive component.
Abstract:
An article includes walls defining an insulating space therebetween and a vent forming an exit for gas molecules during evacuation of the space. A distance separating the walls is variable in a portion adjacent the vent such that gas molecules are directed towards the vent imparting a greater probability of molecule egress than ingress such that deeper vacuum is developed without requiring getter material. The variable-distance portion may be formed by converging walls. Alternatively, a portion of one of the walls may be formed such that a normal line at any location within that portion is directed substantially towards a vent opening in the other wall.

Изобретение относится к атомной энергетике. Устройство электрообогрева ванны для дезактивации вертикального исполнения содержит размещенный на наружной поверхности ванны для дезактивации нагреватель из проволоки с высоким удельным электрическим сопротивлением с токоподводами и соединительными муфтами и блоки тепловой изоляции. Блоки тепловой изоляции выполнены в виде коаксиальных металлических экранов, которые установлены с воздушным зазором от нагревателя. Нагреватель с токоподводами выполнен в герметичном исполнении. Каждый блок тепловой изоляции дополнен коаксиальным металлическим защитным кожухом. Воздушный зазор между блоком тепловой изоляции и защитным кожухом в верхней части закрыт крышкой с козырьком. На сплошной крышке верхнего защитного кожуха установлена герметичная соединительная муфта. В верхней и нижней части боковой поверхности защитного кожуха выполнены сквозные отверстия. Изобретение позволяет повысить надежность, снизить материалоемкость устройства и упростить монтаж и ремонт устройства.
Abstract:
An appliance includes a metallic outer wrapper having sidewalls, a wrapper backwall and a machine wall. At least one metallic inner liner has liner walls and a liner backwall, wherein the metallic outer wrapper and the at least one metallic inner liner are coupled together at a trim breaker to define a structural cabinet having a hermetically sealed interior cavity defined between the metallic outer wrapper and the at least one metallic inner liner. The trim breaker defines a front face of the structural cabinet. At least one trim breaker conduit extends through the wrapper and liner backwalls wherein the trim breaker conduit defines a conduit through the structural cabinet, and wherein the structural cabinet is hermetically sealed at the trim breaker conduit.
Abstract:
An appliance includes an outer wrapper, an inner liner, a trim breaker having a wrapper channel that receives a wrapper edge of the outer wrapper and a liner channel that receives a liner edge of the inner liner, and an insulation material disposed within an insulating cavity defined therebetween. A multi-component thermal encapsulation material defines pre-mix, application and sealing states. The pre-mix state is defined by the distinct components of the thermal encapsulation material being separated from one another, the application state defined by the distinct components combined together into an uncured state of the thermal encapsulation material, and the sealing state defined by the thermal encapsulation material disposed within the wrapper and liner channels and surrounding the wrapper and liner edges, respectively, in the sealing state that defines a hermetic seal between the trim breaker and the outer wrapper and the inner liner.
Abstract:
A presente invenção refere-se a ARCOS ESPIRAIS METÁLICOS DE ALTO DESEMPENHO DE CONSERVAÇÃO DE ENERGIA, com sistema interno de sustentação e resistência ao amassamento, para aplicação em equipamentos, tubulações e ramais de aquecimento, isentas totalmente de isolantes térmicos tipo massa, como lã de rocha, lá de vidro, fibra cerâmica, perlita, silicato de cálcio, aerogel, etc. de alta resistência térmica, destacável, ou removível. O objeto desta invenção são os ARCOS ESPIRAIS METÁLICOS DE ALTO DESEMPENHO DE CONSERVAÇÃO DE ENERGIA, que foram concebidos e desenvolvidos a partir dos modelos matemáticos de curvas próprias das conhecidas espirais de Arquimedes e as de Newton, Euler, ou Fibonacci, etc. Assim torna-se, seguramente, possível manter, em excelentes níveis, a temperatura e as características físico-químicas dos fluidos ao longo das tubulações e nos equipamentos devido a baixíssima condutividade térmica efetiva do sistema aplicado.
