Ukuze ugcine imikhiqizo ezwelayo ebucayi isikhathi eside, ibhodlela le-cryogenic Dewar uhlelo olunikeza indawo ezinzile yokushisa okuphansi ukugcina impilo yamaseli entekenteke. ICryogenic Dewar wuhlobo lomkhumbi ongacindezeli, owenzelwe ngokukhethekile futhi owenziwe, ongamelana nezinto ze-cryogenic ezihlobene ne-liquid nitrogen. I-nitrogen ewuketshezi ayinaphunga, ayinambala, ayinambitheki futhi ayicasuli; ngakho-ke, ayinazici zokuxwayisa futhi idinga ukuphathwa ngokunakekela. Ekushiseni okuphansi kuka - 196 ℃, i-nitrogen engamanzi ibhekwa njengoketshezi lwe-cryogenic, olungasetshenziswa ukugcina izinto eziphilayo ezinomkhawulo.

ngenxa yobukhona be-nitrogen ewuketshezi, ukwakheka kabusha kungenziwa. Ngokulondolozwa kwesikhathi eside kwamaseli we-stem, izicubu kanye namanye amasampula kumabhodlela we-cryogenic Dewar, izinqubo zokwelashwa kanye nocwaningo kungathuthukiswa futhi.

okulandelayo yizinyathelo ezinhlanu zokuvikela i-cryogenic dewar nokuqukethwe kwayo:

1. Sebenzisa uhlelo lokuqapha izinga lokushisa oluthembekile. Ukuze uvimbele noma yikuphi ukuphendula kwamakhemikhali okungadala ukonakala kwamaseli, imikhiqizo ebucayi kakhulu yezinto eziphilayo kufanele igcinwe emazingeni okushisa aphansi kakhulu emazibeni e-cryogenic. Ukushisa kwesitoreji esiphansi (isib - 196? C) kungagcina izimpilo ezinomkhawulo wokuphila ziphila. Indlela ephumelelayo yokuqinisekisa ukuphepha kokuqukethwe okuphansi kukaDewar nokugcina izinga lokushisa eliphansi ukusebenzisa uhlelo lokuqapha izinga lokushisa lokushisa oluthembekile.
3..Gcina izinga lokushisa eliphansi iDewar iqonde ngaso sonke isikhathi. Ama-cryogenic dewars kufanele agcinwe emile ngaso sonke isikhathi ukuqinisekisa ukugcinwa okuphephile. Ukulahla i-dewar noma ukuyibeka ohlangothini lwayo kungadala uketshezi lwe-nitrogen. Ukulimala kwabashubile noma enye into egcinwe kuyo nakho kungenzeka.
4..Akuphathwa kabi. Ukuphathwa kahle kungadala umonakalo omkhulu kumabhodlela wangaphakathi we-cryogenic Dewar nokuqukethwe. Beka ibhodlela le-Dewar, uliphendulele ohlangothini lwayo, bese uthola umthelela omkhulu nokudlidliza, okungaholela ekulahlekelweni okuncane noma okuphelele komshini. Isistimu ye-vacuum insulation inciphisa umthwalo wokudlulisa ukushisa ketshezi lwe-cryogenic futhi igcina okomkhathi kushisa okuphansi ngaso sonke isikhathi. Isitebhisi sokushisa okuphansi singahlangabezana nobungqabavu besidingo esiphansi sokushisa.
5..Gcina idivayisi ihlanzekile futhi yomile. Umshini kufanele ubekwe endaweni ehlanzekile neyomile. Umswakama, amakhemikhali, izinto zokuhlanza ezinamandla nezinye izinto zikhuthaza ukugqwala futhi kufanele zisuswe ngokushesha. Mane uhlanze ibhodlela le-cryogenic Dewar ngamanzi noma isepha elincane bese womisa kahle ukuvimbela ukubola kwegobolondo lensimbi. Ukulimala kwento esetshenziselwe ukwenza okwehla kungabeka into egciniwe engcupheni.
Gcina umoya owanele. Ukungena kwanoma iyiphi i-cryogenic Dewar akumele kumbozwe noma kuvinjelwe ukugwema ukuphazanyiswa ukukhishwa kwegesi. Ama-dewars awacindezelwa, ngakho-ke ukungena umoya ngokwanele kungaholela ekucindezelekeni ngokweqile kwegesi. Lokhu kungadala ukuthi ibhodlela likaDewar liqhume futhi libe yingozi yokuphepha yabasebenzi nezinto eziphilayo ezigciniwe.
