Ehlabathini le-cryogenics, imfuno yokufakelwa kwe-thermal esebenzayo kunye nethembekileyo iyona nto ibalulekileyo, ngakumbi xa kuziwa ekuthuthweni kwe-supercooled liquids njenge-helium yolwelo.Vacuum imibhobho yeebhatyi(VJP) iteknoloji ephambili ekunciphiseni ukuhanjiswa kobushushu kunye nokuqinisekisa ukuba i-cryogenic fluids efana ne-helium yamanzi ihlala kumaqondo okushisa aphantsi afunwayo ngexesha lokuthutha. Eli nqaku liphonononga indima ebalulekileyo yemibhobho ye-vacuum jacketed kwizicelo ze-helium yolwelo.

Yintoni imibhobho yeJacket yeVacuum?

Vacuum imibhobho yeebhatyi, ekwaziwa njengemibhobho egqunyiweyo, yimibhobho ekhethekileyo ebonisa umaleko wokugquma phakathi kweendonga ezimbini zemibhobho enzulu. Olu luhlu lwe-vacuum lusebenza njengesithintelo se-thermal esisebenza ngokugqithisileyo, esithintela ukuhanjiswa kobushushu ukuya okanye kwimixholo yombhobho. Kwi-helium engamanzi, ebilisa kwiqondo lobushushu elimalunga ne-4.2 Kelvin (-268.95°C), ukugcina amaqondo obushushu aphantsi ngolo hlobo ngexesha lokuhamba kubalulekile ukunqanda ukuguquka kwamanzi kunye nokulahleka kwezinto.

Ukubaluleka kweMibhobho yeJacket yeVacuum kwiiNkqubo ze-Liquid Helium

I-helium yolwelo isetyenziswa kakhulu kumashishini afana nokhathalelo lwempilo (oomatshini be-MRI), uphando lwezenzululwazi (kwii-accelerators zamasuntswana), kunye nokuhlola indawo (kumacandelo okupholisa iziphekepheke). Ukuthuthwa kwe-helium engamanzi ukunqumla imigama ngaphandle kokunyuka okubonakalayo kobushushu kubalulekile ekucutheni inkunkuma kunye nokuqinisekisa ukusebenza kakuhle kwenkqubo.Vacuum imibhobho yeebhatyiziyilelwe ukugcina ulwelo kwiqondo lobushushu obufunekayo ngokunciphisa ngokubonakalayo utshintshiselwano lobushushu.

UkuNcitshiswa kokuFumana koBubushushu kunye nokuLahleka koMphunga

Enye yeenzuzo eziphambili zeimibhobho yokufunxa ibhatyikwiinkqubo ze-helium elulwelo kukukwazi kwabo ukuthintela ukungena kobushushu. Umaleko wevacuum ubonelela ngomqobo ophantse ugqibelele kwimithombo yobushushu yangaphandle, unciphisa kakhulu amazinga okubila. Oku kubalulekile ekugcineni imeko yolwelo lwe-helium ngexesha lothutho kwimigama emide. Ngaphandle kokusetyenziswa kwe-vacuum insulation, i-helium iya kunyuka ngokukhawuleza, ekhokelela kwilahleko yemali kunye nokungasebenzi kakuhle.

Ukuqina kunye nokuguquguquka

Vacuum imibhobho yeebhatyiezisetyenziswe kwiinkqubo ze-helium zamanzi zenzelwe ukuqina, zihlala zakhiwe ngensimbi engenasici okanye ezinye izinto ezinokumelana nokushisa okukhulu kunye noxinzelelo lomatshini. Le mibhobho nayo iza kuyilo oluguquguqukayo, ivumela ukufakwa lula kwiinkqubo ezinokufuna iindlela ezigobileyo okanye eziguquguqukayo. Oku bhetyebhetye kubenza balungele iziseko ezingundoqo ezifana neelebhu, itanki yokugcina i-cryogenic, kunye nothungelwano lwezothutho.

Ukuqukumbela

Vacuum imibhobho yeebhatyiidlala indima ebaluleke kakhulu ekuthuthweni kwe-helium engamanzi, inikezela ngokufakwa kwe-thermal okusebenzayo okucutha ukufumana ubushushu kunye nokunciphisa ilahleko. Ngokugcina ingqibelelo ye-cryogenic liquids, le mibhobho inceda ukugcina i-helium ebalulekileyo kunye nokunciphisa iindleko zokusebenza. Njengoko amashishini eqhubeka nokuvuselela kwaye afuna iinkqubo eziphambili ze-cryogenic, indima yeimibhobho yokufunxa ibhatyiiya kukhula kuphela ukubaluleka. Ngokusebenza kwazo okungenakuthelekiswa nanto kunye nokuqina,imibhobho yokufunxa ibhatyihlala iteknoloji ephambili kwintsimi ye-cryogenics, ngakumbi kwizicelo ze-helium yolwelo.

Ukuququmbela,imibhobho yokufunxa ibhatyi(VJP) ziyimfuneko kwizicelo ze-helium engamanzi, ivumela uthutho olusebenzayo, ukunciphisa inkunkuma, kunye nokuqinisekisa ukhuseleko kunye nokuthembeka kweenkqubo ze-cryogenic.
