Abstract

The invention provides a nonmetal heat regenerator of a Stirling refrigerator with a temperature zone from 160 DEG C below zero to 0 DEG C. The nonmetal heat regenerator comprises a sleeve, wherein aplurality of felt sheets are stacked in the sleeve; the felt sheets are uniformly interwoven by taking nonmetal filaments as warps and wefts; the diameter of the nonmetal filaments is 8-100 microns. Compared with the prior art, a nonmetal material with an appropriate filament diameter is used for weaving felt sheets with appropriate thickness and porosity; the number of the felt sheets is adjustedwhen filling the heat regenerator, namely the filling elasticity is used for controlling the overall porosity of the nonmetal heat regenerator; consistence and high controllability of the overall porosity of the nonmetal heat regenerator can be ensured; the performance and the efficiency of the Stirling refrigerator with the temperature zone can be ensured; the cost of the regenerator is reduced.

Description

technical field [0001] The invention relates to the technical field of Stirling cycle refrigerators, in particular to a non-metal regenerator and a method for manufacturing the non-metal regenerator for a Stirling refrigerator in a temperature range of -160°C to 0°C. Background technique [0002] At present, the working temperature range of the general Stirling refrigerator is around 77K (-196°C). The Tring refrigerator has gradually become a research hotspot, and its requirements for the regenerator are also different from those of the 77K temperature zone refrigerator. [0003] The regenerator is the place where the heat and work of the Stirling refrigerator are converted. After the gas working fluid is compressed by the compressor, it is cooled in the heat exchanger part of the hot end (generally cooled to around 30°C-40°C), and then enters the regenerator for heat exchange. The gas passes through the high-temperature end of the regenerator and gradually flows to the lo...
