Abstract
The invention discloses a dual-moving piston cryo refrigerator, relates to the field of devices of cryogenic cooling, superconductive cooling and the like, and in particular relates to a cryo refirigerator reaches minus 270 DEG C which is used for the cooling of superconductors and other devices. The refrigerator is composed of a driving piston, a power supply, a main radiator, a regenerator, a refrigerator element, a laminor flow device, a second radiator and a phase modulation piston. The driving piston is suspended in a main air cylinder by adopting a flexible bearing and is driven by electromagnetic force; the changes of the volume in the air cylinder are leaded by the motion of the piston, consequently the pressure and the temperatue of air in the air cylinder are changed; the air flows out of the air cylinder when the air is compressed, enters the regenerator after heat dissipation by a heat exchanger, and then enters the refrigerator element through the laminor flow device; and the phase modulation piston is suspended in a second air cylinder by adopting the flexible bearing, and is driven by eletromagnetic force which has a certain phase difference with a main piston, the characteristics of motion for the piston is regulated, the pressure waves and volume wave phase position in the refrigerator element are optimized, thus the refrigerating effect is optimized, and the efficiency of the refrigerator is improved as well as lower temperature is obtained.
Description
Technical field
The present invention relates to be used for device fields such as sub-cooled, superconduction cooling, high vacuum, industrial gasses industry, specifically is the refrigeration machine that can reach subzero 270 degree, and low temperature cold source is provided.
Technical background
Common small-sized Cryo Refrigerator need have moving piston in low-temperature end, because Cryo Refrigerator must not have oil in the low temperature part, causes piston wear serious, and refrigerating efficiency descends, and needs periodic maintenance, and the life-span is restricted.
Goal of the invention
The present invention is directed to serious, the inefficient weak point of refrigeration machine of low temperature piston wear in the above-mentioned technology, a kind of new Cryo Refrigerator has been proposed, this refrigeration machine has been avoided the moving piston of low temperature part, introduce second moving piston at indoor temperature end, both avoided the moving piston of low-temperature end, optimize the performance of Cryo Refrigerator again, improved the whole efficiency of refrigeration machine.Realize that technical scheme of the present invention is as follows: this refrigeration machine has compressor.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure, 1 is active piston (compression piston), and 2 is flexible bearing, and 3 is the phase modulation piston, and 4 is compression chamber, 5 is the phase modulation chamber, and 6 is hot junction laminar flow device, and 7 is cooling module, and 8 is hot end heat exchanger, 9 is regenerator, and 10 is tube connector, and 11 is cold junction laminar flow device, and 12 is cool end heat exchanger.
The specific embodiment
6,11 laminar flow devices are made up of porous metal medium or multiple layer metal silk screen, with the inwall of cooling module excellent contact is arranged, it mainly acts on is the working medium homogenising as far as possible on the cross section of cooling module that will enter cooling module, suppress because cross section of fluid channel changes the turbulent flow that brings, make the working medium fluidized bed fluidisation in the pipe, reduce the various losses that turbulent flow brings, hot junction laminar flow device is also realized the function of the working medium heat transferred environment that will flow through simultaneously.8, the 12nd, heat exchanger, its structure is an airtight small sircle hole on the red copper element, the diameter of circular hole is according to exchanging the mobile frequency and the thermal penetration depth of working medium.Element 8 main heat transferred surrounding environment with working medium.Element 11 and 12 mainly is to be used for cooling off cooled body.
