Cov kua cryogenic siv rau ntau yam lag luam, suav nrog kev kho mob, aerospace, thiab lub zog. Cov kua txias heev no, xws li kua nitrogen thiab kua helium, feem ntau yog khaws cia thiab thauj mus rau hauv cov thawv tshwj xeeb uas tsim los tswj lawv qhov kub qis. Hom thawv feem ntau siv los tuav cov kua cryogenic yog lub raj mis Dewar.
Cov raj mis Dewar, tseem hu ua lub raj mis nqus tsev lossis lub raj mis thermos, yog tsim tshwj xeeb los khaws thiab thauj cov kua cryogenic ntawm qhov kub qis heev.Feem ntau lawv yog ua los ntawm cov hlau tsis xeb lossis iav thiab muaj ob phab ntsa nrog lub tshuab nqus tsev ntawm cov phab ntsa. Lub tshuab nqus tsev no ua haujlwm ua lub rwb thaiv cua sov, tiv thaiv kom tsis txhob muaj cua sov nkag mus rau hauv lub thawv thiab ua kom cov kua dej cryogenic sov.
Phab ntsa sab hauv ntawm lub raj mis Dewar yog qhov chaw khaws cov kua cryogenic, thaum phab ntsa sab nraud ua haujlwm ua ib qho kev tiv thaiv thiab pab kom ntxiv rwb thaiv cov ntsiab lus. Sab saum toj ntawm lub raj mis feem ntau muaj lub hau lossis lub hau uas tuaj yeem kaw kom tiv thaiv kev khiav tawm ntawm cov kua cryogenic lossis roj.
Ntxiv rau Dewar flasks, cov kua cryogenic kuj tseem tuaj yeem khaws cia rau hauv cov thawv tshwj xeeb xws li cov tank cryogenic thiab cov thooj voos kheej kheej. Cov thawv loj dua no feem ntau siv rau kev khaws cia ntau lossis rau cov ntawv thov uas xav tau kev siv cov kua cryogenic ntau, xws li hauv cov txheej txheem kev lag luam lossis cov chaw kho mob.
Cov tank cryogenicFeem ntau yog cov hlab loj, ob phab ntsa uas tau tsim los khaws thiab thauj cov kua dej cryogenic ntau, xws li kua nitrogen lossis kua oxygen. Cov tank no feem ntau siv rau hauv kev lag luam xws li kev kho mob, qhov chaw uas lawv siv los khaws thiab thauj cov kua dej cryogenic qib kho mob rau cov ntawv thov xws li cryosurgery, cryopreservation, thiab kev thaij duab kho mob.
Cov thooj voos kheej kheej cryogenic, ntawm qhov tod tes, yog cov thawv me me, nqa tau uas tsim los rau kev khaws cia thiab thauj cov kua cryogenic me me. Cov thooj voos kheej kheej no feem ntau siv rau hauv chaw soj nstuam, chaw tshawb fawb, thiab chaw ua haujlwm uas xav tau lub thawv me dua, nqa tau ntau dua rau kev thauj cov kua cryogenic.
Txawm yog hom thawv twg siv los xij, kev khaws cia thiab tuav cov kua dej cryogenic yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thiab cov txheej txheem tuav kom raug. Vim tias qhov kub qis heev, yuav tsum tau ceev faj tshwj xeeb kom tiv thaiv kev mob frostbite, kub hnyiab, thiab lwm yam kev raug mob uas tuaj yeem tshwm sim thaum tuav cov kua dej cryogenic.
Ntxiv rau qhov txaus ntshai ntawm lub cev, cov kua dej cryogenic kuj tseem muaj kev pheej hmoo ntawm kev ua pa tsis taus yog tias lawv raug tso cai kom ua pa thiab tso tawm ntau cov pa roj txias. Vim li no, yuav tsum muaj cov txheej txheem cua thiab kev nyab xeeb kom zoo kom tiv thaiv kev sib sau ua ke ntawm cov pa roj cryogenic hauv qhov chaw kaw.
Zuag qhia tag nrho, kev siv cov kua dej cryogenic tau hloov pauv ntau yam lag luam, txij li kev kho mob mus rau kev tsim hluav taws xob. Cov thawv tshwj xeeb siv los khaws cia thiab thauj cov kua dej txias heev no, xws li Dewar flasks,cov tank cryogenic, thiab cov thooj voos kheej kheej, ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov khoom muaj nqis no. Thaum thev naus laus zis txuas ntxiv mus, kev tsim cov qauv thawv tshiab thiab zoo dua yuav ua rau muaj kev nyab xeeb thiab kev ua haujlwm zoo ntawm kev khaws cia thiab thauj cov kua dej cryogenic.
