Ibhodlela le-cryogenic Dewar, elenziwa nguSir James Dewar ngo-1892, liyisiqukathi sokugcina izinto. Isetshenziswa kabanzi ekuthuthweni nasekubekweni kokuphakathi okuwuketshezi (i-nitrogen ewuketshezi, i-oxygen engamanzi, i-argon ewuketshezi, njll.) Kanye nomthombo obandayo weminye imishini yesiqandisi. I-cryogenic Dewar inamabhodlela amabili, elinye libekwe kolunye futhi lixhunywe entanyeni. Igebe eliphakathi kwamabhodlela amabili liwuthulula kancane umoya, lenze i-vacuum eseduze, eyehlisa kakhulu ukudluliswa kokushisa ngokuqhutshwa noma ukuhanjiswa.

izinzuzo zomkhiqizo:

I-1.Kusetshenziselwa kakhulu ukuthuthwa nokugcinwa komoya-mpilo, uketshezi lwe-nitrogen, i-argon ewuketshezi kanye negesi engokwemvelo
2. Uhlangothi oluphakeme lwe-vacuum multilayer luqinisekisa izinga eliphansi lokuhwamuka, futhi ithuluzi le-valve lokungena liqinisekisa ukusebenza okuhle
3. I-evaporator eyakhelwe ngaphakathi inikezela nge-9nm3 / h igesi eqhubekayo eqhubekayo
4. Isikhala segesi sokucindezela ngokweqile sisetshenziswa kudivayisi mpintsha
5. I-Pole enesixhumi esijwayelekile se-CGA
6. Idizayini eyingqayizivele yokwakheka kwendandatho ingahlangabezana nezidingo zokuhamba njalo

amabhodlela e-cryogenic Dewar asetshenziswe kabanzi ekusetshenzisweni kwemishini, ukusika i-laser, ukwakha umkhumbi, ezokwelapha, ukufuya izilwane, i-semiconductor, ukudla, amakhemikhali asezingeni eliphansi, i-aerospace, amasosha nezinye izimboni nezinsimu. Imodeli yokusetshenziswa inezinzuzo zomthamo omkhulu wokugcina, izindleko zokuhamba eziphansi, ukuphepha okuhle, ukunciphisa ukungcoliswa kwegesi nokuphathwa okulula.

Ngokuvamile, ibhodlela likaDewar linama-valve amane, okungukuthi i-valve yokusetshenziswa ketshezi, i-valve yokusebenzisa igesi, i-valve ye-vent kanye ne-booster valve. Ngaphezu kwalokho, kunegeji yomfutho wegesi negeji yeleveli yamanzi. Ibhodlela le-Dewar alihlinzekwa kuphela nge-valve yokuphepha, kepha futhi ne-disc eqhumayo [6]. Lapho ingcindezi yegesi esesilinda yeqe ingcindezi yohambo ye-valve yokuphepha, i-valve yokuphepha izogxuma ngokushesha futhi ikhiphe ngokuzenzekelayo futhi iqede ingcindezi. Uma i-valve yezokuphepha ihluleka noma isilinda sonakele ngengozi, ingcindezi esesilinda ikhuphuka kakhulu ezingeni elithile, isethi yamapuleti okuqhuma izokwehla ngokuzenzakalela, futhi ingcindezi ekulesi silinda izokwehliswa ibe ingcindezi yasemkhathini ngesikhathi. Amabhodlela eDewar agcina i-oxygen liquid liquid, eyandisa kakhulu umthamo wokugcina umoya-mpilo.
