Botolo la cryogenic Dewar, lopangidwa ndi Sir James Dewar mu 1892, ndi chidebe chosungira. Amagwiritsidwa ntchito kwambiri poyendetsa ndi kusungira sing'anga wamadzi (madzi asafe, mpweya wamadzi, madzi a argon, ndi zina zambiri) komanso kuzizira kwa zida zina za firiji. Dewar ya cryogenic imakhala ndi mabotolo awiri, imodzi imayikidwa mzake ndikulumikizana pakhosi. Kusiyanitsa pakati pa mabotolo awiriwo kumatsitsa mpweya pang'ono, ndikupangitsa kuti pakhale zotulutsa pang'ono, zomwe zimachepetsa kwambiri kutentha kwanyumba kudzera pakupitilira kapena kugundika.

Ubwino mankhwala:

1.It zimagwiritsa ntchito mayendedwe ndi kusunga mpweya madzi, nayitrogeni madzi, madzi argon ndi liquefied gasi
2. Mkulu zingalowe multilayer kutchinjiriza mbali zipangitsa otsika mlingo evaporation, ndi polowera vavu chida kumathandiza ntchito bwino
3. evaporator yokhazikika imangopereka 9nm3 / h mpweya wokhazikika mosasunthika
4. Gasi loponderezedwa kwambiri limagwiritsidwa ntchito mu makina opumira
5. Pole yokhala ndi cholumikizira cha CGA wapadziko lonse lapansi
6. Makina osanja a mphete amatha kukwaniritsa zofunikira zoyendera pafupipafupi

Mabotolo a cryogenic Dewar akhala akugwiritsidwa ntchito kwambiri pokonza makina, kudula kwa laser, zomangamanga, zamankhwala, zoweta ziweto, semiconductor, chakudya, mankhwala otentha, malo ogulitsira, magulu ankhondo ndi mafakitale ena. Mtundu wogwiritsa ntchito uli ndi maubwino osungira kwakukulu, mtengo wotsika wa mayendedwe, chitetezo chabwino, kuchepetsa kuwonongeka kwa gasi ndi kuwongolera kosavuta.

Nthawi zambiri, botolo la Dewar limakhala ndi mavavu anayi, omwe ndi ma valve ogwiritsira ntchito madzi, valavu yogwiritsa ntchito gasi, valavu yotulutsa mpweya ndi valavu yolimbikitsira. Kuphatikiza apo, pali gauge yamagetsi yamagetsi ndi gauge yamafuta amadzi. Botolo la Dewar sikuti limangopatsidwa valavu yachitetezo, komanso ndi disc yophulika [6]. Kuthamanga kwa gasi mu silinda kupitilira kuthamanga kwa valavu yachitetezo, valavu yachitetezo imangodumpha ndikungotulutsa ndikuzimitsa mavuto. Valavu yachitetezo ikalephera kapena silinda yawonongeka mwangozi, kuthamanga kwa silinda kumakwera kwambiri pamlingo winawake, mbale yolimbirana yophulika imangoduka zokha, ndipo kuthamanga kwa silinda kumachepetsedwa kukhala kupsinjika kwam'mlengalenga munthawi yake. Mabotolo a Dewar amasunga mpweya wamankhwala wamankhwala, womwe umakulitsa kwambiri kusungira mpweya.
