Stainless hlau thiab aluminium alloys feem ntau yog siv rau kev tsim kho ntawm lub nkoj sab hauv, thaum carbon hlau feem ntau siv rau lub plhaub sab nraud. Cov ntaub ntawv no tau txais kev soj ntsuam nruj thiab kev tswj xyuas zoo kom ntseeg tau tias lawv tsim nyog rau cov ntawv thov cryogenic.
Kev khaws cia thiab kev thauj mus los ntawm cov tshuaj cryogenic kuj yuav tsum tau siv cov khoom tshwj xeeb thiab cov khoom siv uas tuaj yeem ua haujlwm tau zoo ntawm qhov kub thiab txias. Cov Cheebtsam no yog tsim los tiv thaiv kev xau thiab tswj kev ncaj ncees ntawm lub tank, txawm tias nyob rau hauv huab cua txias ntawm cryogenic cia. Tsis tas li ntawd, cov tso tsheb hlau luam tau nruab nrog cov twj tso kua mis los tiv thaiv kev kub siab dhau thiab ua kom muaj kev nyab xeeb ntawm kev cia khoom.
Lub hauv paus ntsiab lus ua haujlwm ntawm cryogenic cia tso tsheb hlau luam tseem suav nrog kev siv lub tshuab tub yees kom tswj qhov kub qis hauv lub tank. Cov tshuab no tau tsim los txuas ntxiv tshem tawm cov cua sov ntawm lub tank thiab tswj qhov kub ntawm cov roj liquefied kom nws nyob hauv nws lub xeev cov kua. Lub tshuab tub yees tau ua tib zoo tsim thiab saib xyuas kom ntseeg tau tias lawv ua haujlwm tau zoo thiab kev ntseeg tau, vim tias qhov tsis ua haujlwm tuaj yeem ua rau poob ntawm qhov kub thiab txias thiab qhov muaj peev xwm evaporation ntawm cov khoom hauv lub tank.
Hauv kev lag luam xws li kev kho mob, kev ua zaub mov, thiab kev tsim khoom siv hluav taws xob, cov tso tsheb hlau luam cryogenic ua lub luag haujlwm tseem ceeb hauv kev khaws cia thiab thauj khoom xws li kua nitrogen, kua oxygen, thiab kua helium. Cov tshuaj no yog siv nyob rau hauv ntau yam kev siv, los ntawm kev khaws cia cov qauv tshuaj lom neeg thiab cov khoom siv kho mob kom txias superconducting hlau nplaum thiab cov khoom siv semiconductor. Kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov tso tsheb hlau luam cryogenic yog qhov tseem ceeb los xyuas kom muaj thiab zoo ntawm cov tshuaj no rau ntau yam kev lag luam.
Lub hauv paus ntsiab lus ua haujlwm ntawm cryogenic cia tso tsheb hlau luam tseem yog qhov tseem ceeb hauv thaj chaw ntawm lub zog cia thiab kev thauj mus los. Liquefied natural gas (LNG) thiab kua hydrogen yog siv los ua lwm yam roj rau tsheb thiab hluav taws xob. Kev khaws cia thiab kev thauj mus los ntawm cov khoom siv cryogenic no yuav tsum muaj cov tso tsheb hlau luam tshwj xeeb uas muaj peev xwm tswj tau qhov kub thiab txias thiab tswj cov khoom tshwj xeeb ntawm cov kua dej no. Lub hauv paus ntsiab lus ntawm cryogenic cia yog qhov tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab siv tau zoo ntawm cov roj hluav taws xob no.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cryogenic cia tso tsheb hlau luam tseem yog ib qho tseem ceeb hauv kev lag luam aerospace, qhov twg cryogenic propellants xws li kua oxygen thiab kua hydrogen yog siv nyob rau hauv foob pob ua ntxaij propulsion systems. Cov ntxig no yuav tsum tau khaws cia thiab thauj ntawm cryogenic kub kom tswj lawv qhov siab ntev thiab ntseeg tau cov kev sib txuas ua ke thaum lub foob pob hluav taws. Cryogenic cia tso tsheb hlau luam ua lub luag haujlwm tseem ceeb hauv kev muab cov txheej txheem tsim nyog rau kev khaws cia thiab tuav cov khoom siv no hauv kev lag luam aerospace.
Hauv kev xaus, lub hauv paus ntsiab lus ua haujlwm ntawmcryogenic cia tanksyog raws li cov hauv paus ntsiab lus ntawm thermodynamics, engineering, thiab material science. Cov tso tsheb hlau luam no tau tsim los tswj qhov ntsuas kub qis uas yuav tsum tau khaws cia thiab thauj cov roj liquefied, thaum ua kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm lub kaw lus cia. Cov txheej txheem rwb thaiv tsev, cov khoom siv, cov li qub, thiab cov tshuab tub yees siv hauv cov tso tsheb hlau luam cryogenic tau ua tib zoo tsim thiab sim ua kom tau raws li qhov tshwj xeeb ntawm kev tuav cov tshuaj cryogenic. Txawm hais tias nyob rau hauv kev lag luam, lub zog, lossis kev siv dav hlau, cov tso tsheb hlau luam cryogenic yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev nyab xeeb ntawm cov roj liquefied ntawm qhov kub thiab txias.
