Abstract

The invention relates to an adiabatic suspension, and discloses a super adiabatic technology based on the structural adiabatic principle. A super adiabatic structure with sufficient mechanical strength is realized through collaborative design of adiabatic material, thermal structure, mechanical structure and applicable functions. The adiabatic suspension is characterized by comprising super adiabatic material (silica aerogel or aluminum oxide aerogel or the like), an adiabatic suspending line (aramid or acrylic fibers, silica cantilevers, metal springs and the like), an adiabatic suspension structure (a right square pyramid suspension, a cube suspension and the like), a rigid suspension bucket (an aluminum alloy casing with the surface provided with an aluminum oxide cladding) and a thermal short circuit structure (a graphite particle painting layer with high thermal conductivity or a soaking film formed by copper foils or silver foils ). The adiabatic suspension can serve as a fundamental paradigm for the thermal engineering technology and the packaging technology, and can be used for designing various new concept products, which can operate under super low temperature or super high temperature, such as adiabatic suspension batteries, adiabatic levitation batteries and adiabatic temperature sensing chips, with super adiabatic performances.

Description

1. Technical field [0001] The present invention "Adiabatic Suspension" [*Patent 1] discloses a "thermal communication and association" technology based on physical connection between different systems in a physical space, which is characterized by the use of "thermal insulation materials and their physical structures" to form A kind of "thermal insulation boundary" between different systems in space, also known as "thermal insulation boundary". This is a "super thermal insulation" technology based on the principle of "structural thermal insulation". It builds a "super thermal insulation structure" with sufficient mechanical strength through the collaborative design of thermal insulation materials, thermal structures, mechanical structures, and application functions. The present invention discloses three typical physical forms of "thermal insulation suspension" and their implementation schemes: first, a kind of "thermal insulation material 'wire' and 'rope' spring used to suspe...
