Ukudluliselwa kwe-LN₂: Iinkqubo ezifakwe i-Vacuum Insulated ze-High-Purity Liquid Nitrogen

Iinkqubo zokudlulisa i-nitrogen engamanzi kulindeleke ukuba zenze into enye kakuhle kakhulu: ukugcina i-LN₂ ibanda kwaye izinzile ukusuka kwitanki yokugcina ukuya kwindawo yokusetyenziswa. Kwiindawo zoshishino zokwenyani, ngakumbi ukusetyenziswa kwegesi ye-semiconductor kunye ne-high-purity, nokuba kukungena kobushushu okuncinci kunokudala ukwakheka komphunga, ukungazinzi koxinzelelo, okanye iimeko zokuhamba okungahambelaniyo.

At Ii-HL Cryogenics, siyilaumbhobho ogqunyiweyo we-vacuumkwayeipayipi eguquguqukayoiinkqubo ngokukodwa zokudluliselwa kwe-LN₂ kumgama omde kunye nokulahleka okuncinci kobushushu. Ngokudibanisa i-vacuum insulation egcinwe ngokuguquguqukayo,iivalvu ezigqunyiweyo zokucoca ulwelokunyeiteknoloji yokwahlula isigaba, iinkqubo zethu ziyakwazi ukugcina ukuhanjiswa kolwelo oluzinzileyo lwesigaba esinye kwiinethiwekhi zokusasazwa kwe-cryogenic ezintsonkothileyo.

Kutheni i-Vacuum Insulation ibalulekile xa kudluliswa i-LN₂

I-nitrogen engamanzi isebenza malunga ne--196 °C. Xa amaqondo obushushu ehlala engaphezulu kwe-25 °C, umahluko wobushushu eludongeni lombhobho ungadlula i-200 °C. Ngaphandle kobushushu obusebenzayo, ubushushu bungena ngokukhawuleza kwinkqubo ngokuhambisa, ukuhambisa, kunye nemitha, okuvelisa igesi yokubilisa kunye nokuhamba okungazinzanga kwezigaba ezibini.

Zethuumbhobho ogqunyiweyo we-vacuumIinkqubo zisebenzisa isakhiwo sentsimbi engenasici esinodonga oluphindwe kabini esinesithuba esiphezulu se-vacuum annular esihlala sigcinwa ngaphantsi kwe-1 × 10⁻⁵ mbar. Phantsi kwale meko, ukuhanjiswa kwegesi kunye ne-convection phantse ziphelile. I-Multilayer insulation (MLI) inciphisa ngakumbi ukudluliselwa kobushushu ngokubonisa amandla e-infrared kude nombhobho wangaphakathi obandayo.

Xa kuthelekiswa nokugquma kwe-foam eqhelekileyo, ukuhanjiswa kobushushu okusebenzayo kuphantsi kakhulu, okuvumela i-LN₂ ukuba idluliselwe ngaphezulu kwamakhulu eemitha ngelixa igcina imeko yolwelo kunye noxinzelelo oluzinzileyo.

Inkqubo yePompo yeDynamic VacuumUzinzo Lwexesha Elide

Enye yeengxaki eziqhelekileyo kwi-cryogenic insulation kukonakala kancinci kancinci kwe-vacuum ngokuhamba kwexesha. Ukuphuma kwegesi eseleyo kwiindawo zentsimbi engagqwaliyo, izinto zokufaka ubushushu, kunye nokuphuma kwegesi encinci kunyusa kancinci uxinzelelo lwe-annulus, kunciphisa ukusebenza kobushushu.

Ukujongana nale nto,Ii-HL Cryogenicsidibanisa iInkqubo yePompo yeDynamic Vacuumkwinethiwekhi yokudlulisa. Inkqubo iqhubeka okanye ikhupha isithuba se-annular ukugcina iimeko zokungasebenzi kakuhle zizinzile kulo lonke ixesha lokusebenza.

Imodyuli ye-vacuum idla ngokuquka:

• Iimpompo zomoya owomileyo okanye i-turbomolecular vacuum
• Iigeyiji zokujonga umatshini wokuhlamba impahla
• Iiyunithi zokufunxa isihluzo semolekyuli
• Iivalvu zokuzahlula kunye nezokungabuyisi

Le ndlela yokugcinwa kwe-vacuum esebenzayo igcina ukusebenza kwe-insulation kuhambelanayo kwiminyaka yokusebenza kwaye ibaluleke kakhulu kwiindawo ze-semiconductor apho ukuzinza kobushushu be-LN₂ kuchaphazela ngokuthe ngqo ukuphindaphinda kwenkqubo.

Ukuhanjiswa okuzinzileyo kweSigaba esinye kunyeIivalvu ezifakwe i-vacuumkwayeAbahluli beSigaba

Kwiinkqubo zokudlulisa amanzi amdaka, ukugcina ukuhamba kolwelo lwesigaba esinye kubalulekile. Iipokotho zomphunga ngaphakathi kombhobho zinokukhokelela ekuhambeni okungazinziyo, ukuxinana kwamanzi, ukuguquguquka koxinzelelo, kunye nokuthembeka kwenkqubo okunciphileyo.

Zethuiivalvu ezigqunyiweyo zokucoca ulweloZenzelwe iibhonethi ezifakwe ijacket ye-vacuum ukuze kuncitshiswe ukungena kobushushu kwindawo ethile emzimbeni wevalvu. Ukupakisha isiqu kubekwe ngaphandle kwendawo ekrwada ukuthintela ukubanda nokuqinisekisa ukusebenza okuthembekileyo ngexesha lokujikeleza ngokuphindaphindiweyo.

Ezantsi komlambo,izahluli zesigaba ezigqunyiweyo nge-vacuumsusa umphunga oqulunqwe ngexesha lokudluliselwa. I-LN₂ ingena kwi-separator ngendlela ethe tyaba, ivumela ii-gas kunye ne-liquid phases ukuba zahlukane ngokufanelekileyo ngaphambi kokuba ulwelo luqhubeke lusiya ezantsi.

Olu didi lunceda ukugcina uxinzelelo oluzinzileyo kwaye luqinisekisa ukuba izixhobo ezisezantsi zifumana i-nitrogen engamanzi ecocekileyo, epholileyo.

Ukuhlanganiswa kweTanki encinci kwiiNethiwekhi zeLN₂ ezisasaziweyo

Kwizakhiwo ezinemfuno eguquguqukayo okanye izikhululo ezininzi zokusetyenziswa, ukubethelela okuphakathi kunokuphucula kakhulu uzinzo lwenkqubo.

ZethuUthotho lweTanki elincinci, ukusuka kwi-100 L ukuya kwi-3 000 L, ibonelela ngendawo yokugcina i-LN₂ kufutshane nezixhobo zokusebenza. Itanki nganye isebenzisa i-vacuum insulation kunye ne-low-conductivity yangaphakathi yokuxhasa ukunciphisa uxinzelelo oluzilawulayo kunye nokulahleka kobushushu.

Xa isebenza ngokoqobo, iiMini Tanks ziyanceda:

• Funxa ukuguquguquka koxinzelelo

Olu lwakhiwo lusetyenziswa kakhulu kwiifektri ze-semiconductor, iilebhu, kunye neenkqubo zokusasazwa kwegesi kwimizi-mveliso.

Ukusebenza kwenkqubo kunye noyilo lobuNjineli

IsiqheloIi-HL CryogenicsInkqubo yokudlulisa i-LN₂ isebenza phakathi kwe-3 kunye ne-10 bar kunye nesantya sokuhamba esifikelela kwi-8 m/s.

Iqinileumbhobho ogqunyiweyo we-vacuumidla ngokusetyenziselwa ukubaleka okuthe tye ixesha elide, ngelixai-vacuum egqunyiweyo eguquguqukayoIinxalenye zepayipi zifakelwe kwiindawo zokudibanisa izixhobo, iindawo zokwandisa, okanye kwiindawo ezifuna imbuyekezo yokuhamba.

Phantsi kweemeko zokusebenza ezizinzileyo, ukuvuza kobushushu ngokubanzi kungancitshiswa kube malunga ne-0.25–0.5 W/m ngokuxhomekeke kulwakhiwo lomgca. Kwiiprojekthi ezininzi, oku kuvumela i-nitrogen engamanzi ukuba ihambe amakhulu eemitha ngokuveliswa komphunga okuncinci.

Amacandelo e-flexible hose asebenzisa ii-cores zangaphakathi ze-stainless steel ezingama-316L ezidityaniswe nee-strainer braids zangaphandle zokumelana noxinzelelo kunye nobomi benkonzo ende.

Isicelo seSemiconductor Fab eMpuma Asia
