Vacuum insulated umbhobho(VIP) idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zobuchwepheshe obuphezulu, ngakumbi kwiinkqubo ze-molecular beam epitaxy (MBE).MBEbubuchule obusetyenziselwa ukwenza iikristale ze-semiconductor ezikumgangatho ophezulu, inkqubo ebalulekileyo kwizinto zombane zanamhlanje, kubandakanywa izixhobo ze-semiconductor, iteknoloji yelaser, kunye nezixhobo eziphambili. Ukugcina ubushushu obuphantsi kakhulu ngexesha lezi nkqubo kubalulekile, kwaye vacuum insulated umbhobhoiteknoloji iqinisekisa uthutho olusebenzayo lwe-cryogenic liquids ukugcina ezo meko ziyimfuneko. Le blog iya kuphonononga indima kunye nokubalulekavacuum insulated umbhobhokwiinkqubo ze-MBE.

Yintoni i-Molecular Beam Epitaxy (MBE)?

I-molecular beam epitaxy (MBE) yinkqubo elawulwa kakhulu yokukhulisa iifilimu ezibhityileyo zezinto eziphathekayo, ezihlala zisetyenziselwa ukuveliswa kwee-semiconductors. Inkqubo yenzeke kwindawo ephezulu ye-vacuum, apho imiqadi yee-athomu okanye iamolekyu iqondiswe kwi-substrate, evumela ukukhula kwe-layer-by-layer ye-crystals ngolawulo oluchanekileyo. Ukugcina ingqibelelo yale nkqubo, amaqondo obushushu aphantsi kakhulu ayafuneka, kulapho kevacuum insulated umbhobhoiteknoloji iba yimfuneko.

Indima yeVacuum Insulated Pipe in MBE Iinkqubo

Vacuum insulated umbhobhoisetyenziswa kwiMBEiinkqubo zokuthutha ulwelo cryogenic, ezifana ulwelo nitrogen okanye helium engamanzi, ukupholisa amacandelo ngaphakathi kwinkqubo. Olulwelo lwe-cryogenic lubalulekile ekugcineni i-vacuum ephezulu kakhulu kunye nolawulo lobushushuMBEIinkqubo zifuna ukusebenza ngokugqibeleleyo. Ngaphandle kwe-insulation esebenzayo, i-cryogenic liquids iya kufudumala ngokukhawuleza, okubangela ukungazinzi kweqondo lokushisa kunye nokunciphisa umgangatho wokukhula kwe-epitaxial.

Ivacuum insulated umbhobhoiqinisekisa ilahleko encinci ye-thermal ngexesha lokuthuthwa kwezi zimanzi ze-cryogenic. I-vacuum layer phakathi kwemibhobho yangaphakathi nangaphandle isebenza njenge-insulator esebenza kakhulu, inciphisa ukuhanjiswa kobushushu ngokusebenzisa i-convection kunye ne-convection, ezona zizathu eziphambili zokuguquguquka kweqondo lokushisa kwiinkqubo ze-cryogenic.

NgobaVacuum Insulated Pipe Ibalulekile kwiMBE Iinkqubo

Ukuchaneka okuphezulu okufunekayo kwiMBEiinkqubo zenzavacuum insulated umbhobho imfuneko. Ubuchwephesha be-VIP bunciphisa umngcipheko wokubilisa ulwelo lwe-cryogenic, olunokuphazamisa ukupholisa kwenkqubo kunye nokuzinza kwe-vacuum. Ukongeza, ukusetyenziswa kwe-vacuum insulated imibhobho kunceda ukunciphisa iindleko zamandla ngokunciphisa imfuno yamandla ongezelelweyo okupholisa, ukuphucula ukusebenza kakuhle kwenkqubo.

Enye inzuzo yokusebenzisavacuum insulated umbhobhokwiMBEiinkqubo kukuthembeka kwayo kwexesha elide. Imibhobho yenzelwe ukugcina ukugqunyelelwa kwe-thermal kwithuba elongeziweyo, iqinisekisa ukusebenza okungaguqukiyo kwiindawo ezinovakalelo kakhulu njengeMBE.

Isiphelo:Vacuum Insulated Pipe IyaphuculaMBE Ukusebenza kweNkqubo

Ukudityaniswa kwevacuum insulated umbhobhokwiMBEIinkqubo zibalulekile ekugcineni ukuchaneka okuphezulu kunye nokuzinza kwezi nkqubo zifunwayo. Ngokunciphisa ukutshintshwa kobushushu, iteknoloji ye-VIP iqinisekisa ukuba i-cryogenic liquids ihlala kumaqondo aphantsi afunekayo, ukukhuthaza ukukhula okufanelekileyo kwe-semiconductor kunye nokunciphisa iindleko zokusebenza. NjengokoMBEiteknoloji iyaqhubeka ukuqhubela phambili, indima yevacuum insulated umbhobhoekuxhaseni ezi nkqubo ziya kuhlala ziyimfuneko.
