Vacuum insulated ipayipi(VIP) idlala indima ebalulekile emikhakheni ehlukahlukene yobuchwepheshe obuphezulu, ikakhulukazi ezinhlelweni ze-molecular beam epitaxy (MBE).MBEkuyindlela esetshenziselwa ukwakha amakristalu e-semiconductor ekhwalithi ephezulu, inqubo ebalulekile ku-electronics yesimanje, okuhlanganisa amadivaysi e-semiconductor, ubuchwepheshe be-laser, nezinto ezithuthukisiwe. Ukugcina amazinga okushisa aphansi kakhulu phakathi nalezi zinqubo kubalulekile, futhi vacuum insulated ipayipiubuchwepheshe buqinisekisa ukuthuthwa okuphumelelayo koketshezi lwe-cryogenic ukuze kugcinwe lezo zimo ezidingekayo. Le bhulogi izohlola indima nokubaluleka kwayovacuum insulated ipayipiezinhlelweni ze-MBE.

Iyini i-Molecular Beam Epitaxy (MBE)?

I-epitaxy ye-molecular beam (MBE) kuyinqubo elawulwa kakhulu yokukhula kwamafilimu amancane ezinto zokwakha, avame ukusetshenziswa ekukhiqizeni ama-semiconductors. Inqubo yenzeka endaweni ye-vacuum ephezulu, lapho imishayo yama-athomu noma ama-molecule iqondiswe ku-substrate, okuvumela ukukhula kongqimba nongqimba lwamakristalu ngokulawula okunembile. Ukugcina ubuqotho bale nqubo, amazinga okushisa aphansi kakhulu ayadingeka, okuyilaphovacuum insulated ipayipiubuchwepheshe buba bubalulekile.

Iqhaza likaVacuum Insulated Pipe in MBE Amasistimu

Vacuum insulated ipayipiisetshenziswa kuMBEamasistimu okuthutha uketshezi lwe-cryogenic, njenge-nitrogen ewuketshezi noma i-helium ewuketshezi, ukupholisa izingxenye ngaphakathi kwesistimu. Lezi ziphuzo ze-cryogenic zibalulekile ekugcineni i-vacuum ephezulu kakhulu kanye nokulawula izinga lokushisa lokhoMBEamasistimu adinga ukusebenza kahle. Ngaphandle kokufakwa okusebenzayo, uketshezi lwe-cryogenic lungafudumala ngokushesha, okuholela ekungazinzini kwezinga lokushisa futhi kubeke engcupheni ikhwalithi yokukhula kwe-epitaxial.

Ivacuum insulated ipayipiiqinisekisa ukulahlekelwa okuncane okushisayo ngesikhathi sokuthutha lawa ma-cryogenic fluids. Isendlalelo se-vacuum phakathi kwamapayipi angaphakathi nangaphandle sisebenza njengesivikeli esisebenza kahle kakhulu, sinciphisa ukudluliswa kokushisa nge-conduction kanye ne-convection, okuyizimbangela eziyinhloko zokuguquguquka kwezinga lokushisa ezinhlelweni ze-cryogenic.

KunganiVacuum Insulated Pipe Ibalulekile kuMBE Amasistimu

Ukunemba okuphezulu okudingekayo kuMBEamasistimu enzavacuum insulated ipayipi isidingo. Ubuchwepheshe be-VIP bunciphisa ubungozi bokubilisa uketshezi lwe-cryogenic, okungaphazamisa ukupholisa kwesistimu nokuzinza kwe-vacuum. Ukwengeza, ukusetshenziswa kwamapayipi afakwe i-vacuum insulation kusiza ukunciphisa izindleko zamandla ngokunciphisa isidingo samandla okupholisa engeziwe, kuthuthukise ukusebenza kahle jikelele kwesistimu.

Enye inzuzo yokusebenzisavacuum insulated ipayipiphakathiMBEamasistimu ukwethembeka kwayo kwesikhathi eside. Amapayipi aklanyelwe ukugcina ukufakwa kwe-thermal esikhathini eside, ukuqinisekisa ukusebenza okungaguquki ezindaweni ezibucayi kakhulu njengeMBE.

Isiphetho:Vacuum Insulated Pipe IyathuthukisaMBE Ukusebenza Kwesistimu

Ukuhlanganiswa kwevacuum insulated ipayipiphakathiMBEamasistimu abalulekile ekugcineni ukunemba okuphezulu nokuzinza kwalezi zinqubo. Ngokunciphisa ukudluliswa kokushisa, ubuchwepheshe be-VIP buqinisekisa ukuthi uketshezi lwe-cryogenic luhlala emazingeni okushisa aphansi adingekayo, lukhuthaze ukukhula kwe-semiconductor okulungile nokunciphisa izindleko zokusebenza. NjengobaMBEubuchwepheshe buyaqhubeka nokuthuthuka, indima yevacuum insulated ipayipiekusekeleni lezi zinqubo kuzohlala kudingekile.
