Thaum cov lag luam txuas ntxiv tshawb nrhiav cov kev daws teeb meem hluav taws xob huv dua, cov kua hydrogen (LH2) tau tshwm sim los ua cov roj zoo rau ntau yam kev siv. Txawm li cas los xij, kev thauj mus los thiab khaws cia cov kua hydrogen xav tau cov thev naus laus zis siab heev los tswj nws lub xeev cryogenic. Ib qho thev naus laus zis tseem ceeb hauv thaj chaw no yoglub raj xa dej nqus tsev vacuum, uas ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua tau zoo ntawm kev xa cov kua hydrogen mus deb.
Nkag Siab Txog Cov Yeeb Nkab Uas Muaj Lub Tshuab Nqus Tsev
Cov kav dej nqus tsev(VJP) yog cov kav dej tshwj xeeb uas tsim los thauj cov kua dej cryogenic, xws li cov kua hydrogen, thaum txo qhov hloov pauv cua sov. Cov kav dej no muaj ib lub kav dej sab hauv, uas tuav cov kua dej cryogenic, thiab ib txheej sab nraud uas muaj lub tshuab nqus tsev uas ua haujlwm ua lub thaiv cua sov. Lub tshuab nqus tsev ntawm cov txheej sab hauv thiab sab nraud yog qhov tseem ceeb hauv kev txo cov cua sov nkag thiab tswj qhov kub qis uas xav tau rau cov kua hydrogen kom nyob hauv nws daim ntawv cryogenic.
Qhov Xav Tau Rau Kev Rwb Thaiv Zoo Hauv Kev Thauj Khoom Hydrogen Ua Kua
Cov kua hydrogen yuav tsum tau khaws cia rau qhov kub qis heev (kwv yees li -253°C lossis -423°F). Txhua qhov cua sov nkag, txawm tias me me xwb los xij, tuaj yeem ua rau vaporization, ua rau poob qhov ntim thiab kev ua haujlwm.lub raj xa dej nqus tsev vacuumua kom cov kua hydrogen nyob twj ywm ntawm qhov kub xav tau, tiv thaiv kev ua kom tsis txhob muaj dej noo thiab ua kom cov hydrogen nyob twj ywm hauv cov kua rau lub sijhawm ntev dua. Qhov kev rwb thaiv tsev zoo no yog qhov tseem ceeb rau cov ntawv thov xws li cov txheej txheem xa roj rau kev tshawb nrhiav qhov chaw, cov tsheb siv hydrogen, thiab kev siv hauv kev lag luam.
Cov txiaj ntsig ntawm Cov Kav Dej Nqus Tsev hauv Cov Ntawv Thov Cryogenic
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmcov kav dej nqus tsev vacuumHauv kev thauj cov kua hydrogen yog lawv lub peev xwm los txo qhov kub nce yam tsis tas yuav siv cov ntaub ntawv rwb thaiv tsev loj lossis tsis yooj yim. Qhov no ua rau lawv yog qhov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov uas xav tau cov txheej txheem compact, txhim khu kev qha, thiab pheej yig. Tsis tas li ntawd, qhov kev tiv thaiv thermal siab uas muab los ntawm lub tshuab nqus tsev rwb thaiv tsev ua kom muaj qhov chaw ruaj khov thiab muaj kev nyab xeeb rau kev khaws cia thiab hloov pauv cov kua hydrogen, txawm tias nyob rau hauv cov xwm txheej sab nraud nyuaj.
Yav Tom Ntej ntawm Cov Kav Dej Nqus Tsev hauv Cov Khoom Siv Hydrogen
Raws li qhov kev thov rau hydrogen nce ntxiv, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm kev hloov pauv zog, lub luag haujlwm ntawmcov kav dej nqus tsev vacuumhauv cov khoom siv hydrogen ua kua yuav tsuas loj hlob xwb. Kev tsim kho tshiab hauv kev tsim cov yeeb nkab, xws li cov ntaub ntawv zoo dua rau kev rwb thaiv tsev thiab cov thev naus laus zis tiv thaiv kev xau, yuav txuas ntxiv txhim kho kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov kab ke no. Hauv xyoo tom ntej, peb tuaj yeem cia siab tiascov kav dej nqus tsev vacuumlos ua lub luag haujlwm tseem ceeb dua hauv kev tsim lub neej yav tom ntej ntawm kev khaws cia thiab faib cov hydrogen.
Xaus lus,cov kav dej nqus tsev vacuumyog qhov tseem ceeb rau kev thauj cov kua hydrogen kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Thaum lub zog hydrogen txuas ntxiv mus thoob ntiaj teb, cov kav dej siab heev no yuav yog qhov tseem ceeb hauv kev txhawb nqa cov khoom siv uas xav tau los xa cov kev daws teeb meem hluav taws xob huv thiab ruaj khov.
