Yintoni iPipe efakwe iVacuum Insulation?
A umbhobho ogqunyiweyo we-vacuumngokusisiseko yinkqubo enamacala amabini eyakhelwe ukuhambisa ulwelo oluyi-cryogenic ngelixa igcina ubushushu bungekho kangangoko kunokwenzeka.
Yenziwe ngamacandelo amathathu aphambili:
Okokuqala, kukho umbhobho wangaphakathi — odla ngokuba yintsimbi engatyiwayo — apho ulwelo oluqhekekayo luhamba khona. Okulandelayo, unembhobho wangaphandle, osebenza njengejakethi yokukhusela nokugcina umbhobho wangaphakathi. Phakathi kwezi, kukho umaleko wokukhusela umbhobho, indawo engenanto enomoya ophumayo, onciphisa kakhulu ukudluliselwa kobushushu.
Ngokukhupha umoya kuloo ndawo, imibhobho egqunywe nge-vacuum insulation ithintela ubushushu ukuba bungangeni nge-conduction okanye nge-convection. Ngaphezu koko, abantu badla ngokongeza i-insulation ekhethekileyo, efana ne-multilayer insulation (MLI), ngaphakathi kwi-vacuum jacket ukuthintela ubushushu obungakumbi obuvela kwimitha.
Iipayipi eziqhelekileyo ezigqunyiweyo azinakukhuphisana — iipayipi ezigqunyiweyo nge-vacuum zivumela ubushushu obuncinci. Oko kuzenza zibaluleke naphi na apho ufuna khona ukugcina ulwelo olubandayo ixesha elide.
Nantsi indlela abasebenza ngayo, ngokucacileyo:
1. Ukumisa ukuHanjiswa koMoya kunye nokuHanjiswa koMoya
Kwimibhobho eqhelekileyo, ubushushu buvuza nge-insulation kunye nomoya okwindawo ejikeleze ulwelo. Ngemibhobho efakwe i-vacuum insulation, umaleko we-vacuum ususa phantse zonke iimolekyuli zomoya, ngoko ke akukho ndlela yokuba ubushushu bungene ngayo ngezo ndlela.
2. Ukunciphisa ukuKhutshwa kweMisebe
Nokuba kukwi-vacuum cleaner, ubushushu bunokudlula njengemitha. Ukujongana nale meko, iinkqubo eziphambili zisebenzisa izinto ezifana ne-multilayer insulation, iileya ze-reflective foil, kunye nezinye izinto ezingakhuphi ubushushu obuninzi ukugcina ubushushu buphantsi.
3. Ukubambelela kumaqondo obushushu aphantsi kakhulu
Ukudibanisa i-vacuum insulation kunye nezithintelo ezibonisa ukukhanya kwenza le mibhobho igcine ulwelo olukhanyayo lubanda kakhulu njengoko luhamba ukusuka kwenye indawo ukuya kwenye.
Umzekelo:
- I-LNG kufuneka ihlale malunga ne--162°C (-260°F)
- I-nitrogen engamanzi ikufutshane ne -196°C (-321°F)
- I-hydrogen engamanzi kufuneka ihle malunga ne--253°C (-423°F)
Imibhobho egqunywe nge-vacuum inceda ukugcina la manzi kubushushu obuphezulu, inciphise ukulahleka kokubila, kwaye yenze yonke inkqubo isebenze ngakumbi.

Ukuba unikezelo aluthembekanga, iinkqubo zemveliso ezibuthathaka azinakwenzeka.
I-aerospace kunye ne-hydrogen energy nazo ziyawunyusa umdlalo wazo we-cryogenic. I-hydrogen engamanzi ngequbuliso iyinkwenkwezi yamandla acocekileyo kwiirokethi kwaye mhlawumbi nakwiimoto zexesha elizayo. Kodwa i-hydrogen inzima—kufuneka ihlale ibanda ngaphezu kwayo nayiphi na enye into, kwaye inovelwano kakhulu kubushushu. Yiyo loo nto, ukuze ugcine okanye uhambise i-LH2, udinga imibhobho egqunywe nge-vacuum. Akukho nto iya kugcina amaqondo obushushu esezantsi ngokwaneleyo.
Amacandelo ezonyango kunye nokhathalelo lwempilo axhomekeke kwiipayipi ezigqunywe nge-vacuum ngezizathu zawo. Uyabona naphi na apho i-nitrogen engamanzi idlala khona: ukugcina iisampulu zebhayoloji, ukusebenzisa iinkqubo zokugcina i-cryogenic, ukuxhasa uphando lwezonyango, kwanakwezinye iindlela zonyango lomhlaza. Iipayipi ezithembekileyo apha zithetha ukuba i-LN2 ihlala ibanda kwaye ayinalahleko ingako—ibalulekile xa ujongene nempilo okanye uphando.
Emva koko kukho ukucubungula ukutya kunye neminye imisebenzi yemizi-mveliso. Iigesi ze-cryogenic zisingatha izinto ezifana nokutya okuqandisa i-flash okanye ukuxhasa amanyathelo okuvelisa okukhethekileyo. Ezi mizi-mveliso zisebenzisa imibhobho egqunywe nge-vacuum ukuqinisekisa ukuba unikezelo luhlala luzinzile kwaye iindleko zokusebenza azinyuki ngenxa yegesi echithwayo.
