Iyo cryogenic Dewar bhodhoro, rakagadzirwa naSir James Dewar muna 1892, mudziyo wakasungirirwa wekuchengetedza. Inoshandiswa zvakanyanya mukufambisa uye chengetedzo yemvura yepakati (mvura senitrogen, okisijeni emvura, mvura yeargon, nezvimwewo) uye inotonhorera sosi yemimwe midziyo yefiriji. Iyo cryogenic Dewar ine mafirask maviri, imwe yakaiswa mune imwe uye yakabatana pamutsipa. Mukaha uripo pakati pemabhasikoro maviri unodurura mweya, uchigadzira padhuze nemhepo, iyo inoderedza zvakanyanya kupisa kupisa kuburikidza ne conduction kana convection.

chigadzirwa zvakwakanakira:

1.Inonyanya kushandiswa kutakura nekuchengetedza mweya weoxygen, liquid nitrogen, liquid argon uye liquefied gasi chaiyo
2. Yepamusoro vharuvhu multilayer kuputira divi inovimbisa yakaderera kubuda kwemvura mwero, uye inlet vharuvhu chiridzwa chechokwadi kuita kwakanaka
3. Iyo yakavakirwa-mukati evaporator inopa otomatiki 9nm3 / h yakagadzikana inoenderera gasi
4. Iyo gasi nzvimbo inodzvinyirira gasi inoshandiswa mune yekugwinha mudziyo
5. Pole pamwe nedzimwe nyika CGA yakajairwa yekubatanidza
6. Iyo yakasarudzika damping mhete dhizaini inogona kusangana nezvinodiwa zvekugara uchifambisa

cryogenic Dewar mabhodhoro ave achishandiswa zvakanyanya mukugadzirwa kwemishini, kucheka laser, kuvaka ngarava, zvekurapa, kuchengeta mhuka, semiconductor, chikafu, yakadzika-tembiricha chemakemikari, muchadenga, kwemauto uye mamwe maindasitiri neminda. Iyo yekushandisa modhi ine zvakanakira hombe yekuchengetedza inokwana, yakaderera kutakura mutengo, chengetedzo yakanaka, kudzikisira kusvibiswa kwegasi uye nyore manejimendi.

Kazhinji kutaura, Dewar bhodhoro ine mavhavha mana, anoti mvura yekushandisa vharuvhu, gasi rekushandisa vharafu, vent vharafu uye booster vharafu. Uye zvakare, kune iyo gasi yekumanikidza geji uye emvura nhanho geji. Bhodhoro reDewar haringopiwi chete nevhavha yekuchengetedza, asiwo nerekuputika disc [6]. Kana kumwe kumanikidza kwemweya uri musilinda kukapfuura kumanikidza kwerwendo rwevhavha yekuchengetedza, iyo vharuvhu yekuchengetedza ichabva yangosvetuka uye zvobva zvangopedza uye kusunungura kumanikidzwa. Kana iyovhavha yekuchengetedza ikakundikana kana iyo humburumbira ikakuvara netsaona, kumanikidza kuri musilinda kukwira zvakanyanya kune imwe nhanho, iyo yekuputika-chiratidzo ndiro yakaiswa ichatsemuka otomatiki, uye kumanikidza kuri musilinda kuchadzikiswa kusvika kumhepo yekudzvinyirira munguva. Dewar mabhodhoro anochengetedza ekurapa emvura okisijeni, iyo inowedzera zvakanyanya iyo oxygen yekuchengetedza kugona.
