Ultralow-temperature vacuum multi-channel combined type dewar

Abstract

The invention discloses an ultralow-temperature vacuum multi-channel combined type dewar which comprises a dewar flask, wherein the dewar flask is internally provided with an air tightness chamber; the side wall of the dewar flask is provided with a multi-channel radio frequency coaxial air-tight seal adapter and a multi-core low frequency air-tight seal connector which are connected to the inner circuits and outer circuits of the dewar, thus the external ports of the dewar flask are reduced, and the integral leakage rate of the dewar is lowered greatly. According to the business necessities, the multi-channel radio frequency coaxial air-tight seal adapter can be distributed on the side wall of the dewar flask by multiple combination methods, the wire cable layout in the dewar flask can be optimized, and the insertion loss and heat dissipation of the wire cable in the dewar can be lowered; and the difficulty of providing an ultralow temperature and long-term high-vacuum degree pressure maintaining working environment is solved effectively, the operation risk occurred during the welding of the multi-channel radio frequency coaxial air-tight seal adapter, the multi-core low frequency air-tight seal connector and the dewar flask is avoided by adopting a flange air-tight connection, the generality and standardization degree of components are improved, the waste product rate is reduced, and the manufacturing, using and maintaining costs of equipment are lowered.

Description

technical field [0001] The invention relates to the field of wireless communication technology using superconducting technology, ultra-low temperature and high vacuum technology, including land and space, mobile and fixed wireless communication. Background technique [0002] Existing wireless communication networks have four major problems that cannot be solved for a long time with existing technologies and equipment. These four major problems are: [0003] 1. Due to the limitations of geographical location (ocean, desert and hills, etc.), environmental protection and rights protection (commercial and residential quarters and cultural relics protection areas, etc.), and station construction conditions (electric power, iron towers, transmission, funds, etc.), it is impossible to solve the communication problem through the new station Coverage hole problem. [0004] 2. Since the wireless terminal equipment is limited by small antenna size, battery capacity, transmission power...

AI Technical Summary

Problems solved by technology

(2) Solve the problem that these components rely on imports, the price is extremely expensive, and the source of goods cannot be guaranteed

(3) Solve the problem that almost no domestic manufacturers can undertake welding, processing and high scrap rate
