The working principle of bellows self-adjustable J-T refrigerator are as follows: high pressure gas reaches throttle orifice by heat-exchange tube 40
500, high pressure gas rapid spatial expansion after small holes, pressure drastically reduces, according to Joule-Thomson effect principle, pressure drop
Gas afterwards substantially cools down, then the cooling detector chip 2 being set on Dewar 20 is formed by fin on heat-exchange tube 40
Gap discharge.Gas is cooled rapidly in inflatable chamber simultaneously, or even liquefaction causes its pressure reduction, thus at the beginning of breaking bellows 70
The balance of beginning compressive state, bellows 70 do stretching motion, drive drive rod 90 mobile, 10 needle point of needle-valve is made to protrude into throttle orifice
In 500, throttle orifice 500, which becomes smaller, is even switched off to control the consumption of gas.Gas pressure after temperature increases, in inflatable chamber
Power increases, and compresses bellows 70, and needle-valve 10 removes from throttle orifice 500, opening throttle orifice 500, realizes repeatedly pair
The self-aligning action of gas flow.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
