Vacuum insulated yeeb nkab(VIP) yog ib qho tseem ceeb hauv kev thauj cov kua dej cryogenic, xws li liquefied natural gas (LNG), kua hydrogen (LH2), thiab kua nitrogen (LN2). Qhov kev sib tw ntawm kev khaws cov kua dej no ntawm qhov kub tsis tshua muaj siab yam tsis muaj kev hloov pauv kub tseem ceeb yog daws los ntawm kev siv tshuab nqus tsev rwb thaiv tsev. Qhov blog no yuav piav qhia li cas lub tshuab nqus tsev insulated yeeb nkabmuab thermal rwb thaiv tsev thiab nws qhov tseem ceeb hauv kev lag luam uas vam khom rau cov tshuab cryogenic.

Dab tsi yog aVacuum Insulated Yeeb Nkab?

A lub tshuab nqus tsev insulated yeeb nkabmuaj ob lub kav dej sib txuas: cov yeeb nkab sab hauv uas nqa cov kua cryogenic thiab cov yeeb nkab sab nraud uas kaw cov yeeb nkab sab hauv. Qhov chaw nruab nrab ntawm ob cov kav dej no tau khiav tawm los tsim lub tshuab nqus tsev, uas ua haujlwm zoo heev thermal insulator. Lub tshuab nqus tsev minimizes tshav kub hloov ntawm conduction thiab convection, uas pab tswj cov kua ntawm nws qhov kub thiab txias.

Lub tshuab nqus tsev rwb thaiv tsev ua haujlwm li cas

Tus yuam sij rau thermal efficiency ntawm alub tshuab nqus tsev insulated yeeb nkab yog lub tshuab nqus tsev. Thaum tshav kub kub hloov feem ntau tshwm sim los ntawm peb txoj kev tseem ceeb: conduction, convection, thiab hluav taws xob. Lub tshuab nqus tsev tshem tawm cov conduction thiab convection vim tias tsis muaj cua molecules hauv qhov chaw nruab nrab ntawm cov kav dej kom hloov cov cua sov. Ntxiv nrog rau lub tshuab nqus tsev, cov yeeb nkab feem ntau suav nrog kev tiv thaiv kev tiv thaiv sab hauv lub tshuab nqus tsev, txo cov cua sov hloov ntawm hluav taws xob.

Vim li casVacuum Insulated Yeeb Nkab Nws yog qhov tseem ceeb rau Cryogenic Systems

Cryogenic kua yog rhiab heev rau qhov kub nce me me, uas tuaj yeem ua rau lawv vaporize, ua rau cov khoom poob thiab muaj peev xwm txaus ntshai.Vacuum insulated yeeb nkabxyuas kom meej tias qhov kub ntawm cov kua dej cryogenic xws li LNG, LH2, lossis LN2 tseem nyob ruaj khov thaum lub sijhawm thauj mus los. Qhov no txo ​​qis cov roj boil-off (BOG) tsim, tswj cov kua hauv nws lub xeev xav tau rau lub sijhawm ntev.

Daim ntawv thov ntawmVacuum Insulated Yeeb Nkab

Vacuum insulated yeeb nkabyog siv nyob rau hauv ntau yam lag luam, nrog rau lub zog, aerospace, thiab kev kho mob teb. Hauv kev lag luam LNG, VIPs tau ua hauj lwm los hloov cov roj liquefied ntawm cov tso tsheb hlau luam thiab cov chaw nres tsheb nrog cov thermal poob tsawg. Hauv kev lag luam aerospace, VIPs ua kom muaj kev nyab xeeb ntawm cov kua dej hydrogen, tseem ceeb heev rau lub foob pob hluav taws. Ib yam li ntawd, hauv kev kho mob, kua nitrogen yog thauj siv VIPs los khaws cov khoom siv roj ntsha thiab txhawb kev siv tshuaj kho mob.

Xaus: Kev Ua Haujlwm ntawmVacuum Insulated Yeeb Nkab

Lub luag haujlwm ntawmlub tshuab nqus tsev insulated yeeb nkab nyob rau hauv cryogenic kua thauj tsis tau overstated. Los ntawm kev txo qis kev hloov hluav taws xob los ntawm cov txheej txheem rwb thaiv tsev siab, VIPs ua kom muaj kev nyab xeeb thiab kev thauj mus los ntawm cov kua cryogenic, ua rau lawv qhov tseem ceeb rau kev lag luam uas nyob ntawm cov thev naus laus zis kub. Raws li qhov kev thov rau cov ntawv thov cryogenic loj hlob, qhov tseem ceeb ntawmlub tshuab nqus tsev insulated kavyuav nce ntxiv, kom ntseeg tau tias thermal efficiency thiab kev nyab xeeb hauv kev ua haujlwm tseem ceeb.
