Qhov Yuav Tsum Tau Ua Thaum Cryogenic

Thaum cov kua hydrogen (LH₂) tshwm sim los ua lub hauv paus tseem ceeb ntawm lub zog huv, nws qhov kub -253°C xav tau cov khoom siv uas feem ntau cov ntaub ntawv tsis tuaj yeem ua haujlwm. Qhov ntawd yog qhovlub tshuab nqus tsev rwb thaiv tsev yooj ywm hosethev naus laus zis dhau los ua qhov tsis sib tham. Yog tsis muaj nws? Hais nyob zoo rau qhov txaus ntshai boil off, kev puas tsuaj ntawm cov qauv, thiab kev ua haujlwm zoo tsis zoo.

Kev Ua Haujlwm ntawm Kev Ua Tau Zoo

Hauv nws lub hauv paus, iblub tshuab nqus tsev vacuum jacketed hoseyog ua zoo li lub thermos ntawm steroids:

Ob lub raj xa dej stainless concentric (feem ntau yog qib 304 / 316L)

Lub annulus uas muaj qhov nqus tsev siab (<10⁻⁵ mbar) uas tsis muaj cov pa roj conductive

30+ txheej MLI uas tiv thaiv kev tawg ua rau muaj kev cuam tshuam los ntawm hluav taws xob nyob nruab nrab

Qhov kev tiv thaiv peb-barrier no ua tiav qhovcov kav dej khov khoua tsis tau: khoov yam tsis tawg thaum lub sijhawm sib txuas tanker thaum khaws cov cua sov hloov pauv hauv qab 0.5 W / m·K. Rau kev xam pom - qhov ntawd yog qhov cua sov tsawg dua li koj lub thermos kas fes.

Vim li cas cov kab txheem tsis ua haujlwm nrog LH₂

Cov hydrogen cov molecule atomic-scale nkag mus rau feem ntau cov khoom siv xws li cov dab los ntawm phab ntsa. Cov hoses ib txwm muaj kev txom nyem los ntawm:

✓ Kev tawg ntawm qhov kub thiab txias

✓ Kev poob ntawm kev nkag (>2% ib zaug hloov)

✓ Cov khoom siv uas txhaws dej khov

Lub raj nqus tsev vacuum jacketedcov txheej txheem tawm tsam qhov no los ntawm:

Cov ntsaws ruaj ruaj hlau-rau-hlau (VCR/VCO fittings)

Cov tubing tubing uas tiv taus kev nkag (electropolished 316L SS)
