Nyob rau hauv lub ntiaj teb ntawm cryogenics, qhov xav tau ntawm cov cua sov thiab txhim khu kev qha cov cua sov thiab txhim khu kev qha tshwj xeeb, tshwj xeeb yog thaum nws los txog rau cov kua roj hmab.Lub tsev txhij cov kav dej(Vjp) yog qhov tseem ceeb thev naus laus zis hauv kev hloov kua cua kub thiab ua kom cov kua roj hmab zoo li cov kua roj helium nyob ntawm qhov kev xav tau qis thaum lub sijhawm thauj mus los. Cov ntawv no tshawb nrhiav lub luag hauj lwm tseem ceeb ntawm lub tshuab nqus tsev uas kav dej uas kav dej hauv cov khoom siv helium.

Dab tsi yog lub tshuab nqus tsev jackinged kav?

Lub tsev txhij cov kav dej, tseem hu ua cov kav dej insulated, yog cov kav dej tshwj xeeb uas muaj lub tshuab nqus tsev ua haujlwm nruab nrab ntawm ob lub phab ntsa yeeb nkab. Lub nqus plua plav ua kev ua raws li qhov kev siv hluav taws xob ua kom muaj txiaj ntsig zoo heev, tiv thaiv kev hloov pauv ntawm tshav kub rau lossis los ntawm cov ntsiab lus ntawm cov yeeb nkab. Rau cov kua helium, uas rhaub ntawm qhov kub ntawm ib puag ncig 4.2 kelvin (-268.95 ° C), tswj cov kub tsawg thaum lub sijhawm hla dej thiab tsis muaj khoom.

Qhov tseem ceeb ntawm lub tshuab nqus tsev jackinged kav rau hauv cov kua helium helium

Cov kua helium tau siv ntau yam hauv kev lag luam xws li kev kho mob (rau cov tshuab muag tshuaj), hauv kev tshawb fawb (rau kev tshawb xyuas txias txias). Thauj cov kua helium nyob deb deb yam tsis muaj kev nce qib ntxiv hauv qhov kub yog qhov tseem ceeb rau kev txo qis thiab ua kom cov txheej txheem ua haujlwm.Lub tsev txhij cov kav dejyog tsim los ua kom cov kua ntawm nws qhov yuav tsum tau kub los ntawm kev hloov pauv kub.

Txo tshav kub kub thiab evaporation tsis tau

Ib qho ntawm cov ntsiab lus tseem ceeb ntawmLub tsev txhij cov kav dejNyob rau hauv cov kua helium helium yog lawv lub peev xwm los tiv thaiv kev kub. Lub tshuab nqus plua plav txheej muab yuav luag thaiv kom muaj cua sov sab nraud, muaj ntau txo tus nqi boil-tawm. Qhov no yog qhov tseem ceeb rau kev tswj hwm lub xeev ua kua ntawm helium thaum lub sijhawm kev thauj mus los ntev. Yog tsis muaj kev siv lub tshuab nqus tsev rwb thaiv tsev, helium yuav sai sai evaporate, coj mus rau ob qho tib si poob thiab ua haujlwm tsis zoo.

Durability thiab hloov tau

Lub tsev txhij cov kav dejSiv nyob rau hauv cov kua helium helium yog tsim rau durability, feem ntau tsim nrog stainless hlau lossis lwm cov ntaub ntawv uas tuaj yeem tiv taus huab cua sov thiab kev ntxhov siab. Cov kav dej no tseem tuaj yeem hloov kho tau yooj yim, tso cai rau cov khoom yooj yim hauv cov tshuab uas yuav xav tau txoj kev nkhaus lossis txoj kev nkhaus. Qhov kev hloov pauv no ua rau lawv zoo tagnrho rau cov txheej txheem nyuaj xws li chaw soj ntsuam, cryogenic tso tsheb hlau luam, thiab tsheb ntiav.

Lub tsev txhij cov kav dejUa si lub luag haujlwm tseem ceeb hauv kev thauj mus los ntawm cov kua roj hmab uas cua sov ua kom muaj kev kub ntxhov ntau heev thiab txo qis. Los ntawm kev tswj hwm kev ncaj ncees ntawm cov kua roj cryogenic, cov kav dej no pab muaj nqis peev muaj nqis helium thiab txo cov nqi ua haujlwm. Raws li kev lag luam txuas ntxiv mus rau Innovate thiab xav tau ntau dua cryogenic tshuab, lub luag haujlwm ntawmLub tsev txhij cov kav dejyuav tsuas yog loj hlob hauv qhov tseem ceeb. Nrog lawv cov khoom siv tsis sib haum cua sov thiab cov kav ntev,Lub tsev txhij cov kav dejNyob twj ywm ib qho tseem ceeb thev naus laus zis nyob rau hauv lub teb ntawm cryogenics, tshwj xeeb rau cov khoom siv helium.

Hauv kev xaus,Lub tsev txhij cov kav dej(Vjp) yog qhov tseem ceeb hauv cov khoom siv helium thiab muaj kev thauj tau yooj yim, txo cov khib nyiab, thiab ua kom muaj kev nyab xeeb thiab ntseeg tau ntawm cryogenic tshuab.
