Ukushaja imoto kagesi kuya ngokushesha ngenxa yobuchwepheshe obusha, futhi kungase kube isiqalo.
Ubuchwepheshe obuningi obuthuthukisiwe obuthuthukiswe yi-NASA bemishini yasemkhathini bathole izinhlelo zokusebenza lapha eMhlabeni.Okwakamuva kwalokhu kungase kube indlela entsha yokulawula izinga lokushisa, engenza ama-EV ashaje ngokushesha ngokunika amandla amandla amakhulu okudlulisa ukushisa, kanjalo namazinga aphezulu okushaja.

Imishini eminingi yesikhathi esizayo ye-NASA izobandakanya izinhlelo eziyinkimbinkimbi okufanele zigcine amazinga okushisa athile ukuze zisebenze.Amasistimu wamandla e-nuclear fission namaphampu okushisa okucindezela umhwamuko okulindeleke ukuthi asetshenziselwe ukusekela ohambweni lweNyanga ne-Mars azodinga amandla athuthukile okudlulisa ukushisa.
Ithimba labacwaningi elixhaswe yi-NASA lenza ubuchwepheshe obusha "okungeke nje kufinyelele ukuthuthukiswa kwe-oda-of-magnitude ekudluliseleni ukushisa ukuze lezi zinhlelo zikwazi ukugcina izinga lokushisa elifanele endaweni, kodwa futhi kuzovumela ukuncipha okukhulu kosayizi nesisindo se-hardware. .”
Lokho kuzwakala njengokuthile okungaba usizo ku-DC enamandla amakhuluiziteshi zokushaja.
Ithimba eliholwa nguSolwazi weNyuvesi yasePurdue u-Issam Mudawar lenze i-Flow Boiling and Condensation Experiment (FBCE) ukuze ivumele ukugeleza koketshezi oluyizigaba ezimbili nokuhlolwa kokudlulisa ukushisa kwenziwe endaweni ye-microgravity ku-International Space Station.
Njengoba i-NASA ichaza: “I-FBCE's Flow Boiling Module ihlanganisa nezinto eziphehla ukushisa ezibekwe eduze kwezindonga zomzila ogeleza lapho okokupholisa kunikezwa kusesimweni soketshezi.Njengoba lezi zisetshenziswa zishisa, izinga lokushisa loketshezi esiteshini liyakhula, futhi ekugcineni uketshezi oluseduze nezindonga luqala ukubilisa.Uketshezi olubilayo lwakha amabhamuza amancane ezindongeni asuka ezindongeni nge-frequency ephezulu, ehlala edonsa uketshezi endaweni engaphakathi yesiteshi ukuya ezindongeni zesiteshi.Le nqubo idlulisela kahle ukushisa ngokusebenzisa kokubili izinga lokushisa eliphansi loketshezi kanye noshintsho olulandelayo lwesigaba ukusuka oketshezini kuya kumhwamuko.Le nqubo yenziwa ngcono kakhulu lapho uketshezi olunikezwa umzila lusesimweni sokuphola kancane (okungukuthi ngaphansi kwephuzu lokubilisa).Lokhu okushaukubila kwe-subcooledumphumela uholela ekusebenzeni okuthuthukisiwe kokudlulisa ukushisa uma kuqhathaniswa nezinye izindlela. ”
I-FBCE yalethwa ku-ISS ngo-Agasti 2021, futhi yaqala ukuhlinzeka ngedatha ebilayo yokugeleza kwe-microgravity ekuqaleni kuka-2022.
Muva nje, ithimba lika-Mudawar lisebenzisa izimiso ezifundwe ku-FBCE kunqubo yokushaja kwe-EV.Kusetshenziswa lobu buchwepheshe obusha, isipholile se-dielectric (esingabambi) simpontshwa ngekhebuli yokushaja, lapho sithwebula ukushisa okukhiqizwa i-conductor ephethe manje.Ukubilisa okugeleza okungapholile kuvumela okokusebenza ukuthi kususe kufika ku-24.22 kW wokushisa.Ithimba lithi uhlelo lwalo lokushaja lunganikeza amandla akhona afinyelela ku-2,400 amps.
Lokho ukuhleleka kobukhulu kunamandla angaphezu kuka-350 noma 400 kW iCCS yanamuhla enamandla kakhulu.amashajangoba izimoto zabagibeli zingabutha.Uma isistimu yokushaja egqugquzelwe yi-FBCE ingaboniswa esikalini sezentengiso, izoba esigabeni esifanayo ne-Megawatt Charging System, okuyizinga lokushaja le-EV elinamandla kakhulu okwamanje elithuthukisiwe (esilaziyo).I-MCS yakhelwe umkhawulo wamanje wama-amps angu-3,000 kufika ku-1,250 V—amandla angaba ngu-3,750 kW (3.75 MW) wamandla aphezulu.Embukisweni wangoJuni, ishaja eyisibonelo ye-MCS yaphuma ngaphezu kwe-MW eyodwa.
