Njira Yoziziritsa ya NASA Itha Kulola Kulipiritsa Kwapamwamba Kwambiri kwa EV

Matekinoloje ambiri apamwamba opangidwa ndi NASA a mishoni mumlengalenga apeza ntchito pano Padziko Lapansi.Zaposachedwa kwambiri mwa izi zitha kukhala njira yatsopano yowongolera kutentha, yomwe imatha kupangitsa kuti ma EV azilipiritsa mwachangu popangitsa kuti pakhale mphamvu zambiri zotumizira kutentha, komanso kuchuluka kwamphamvu kwamagetsi.

Maulendo angapo amtsogolo a NASA adzaphatikiza machitidwe ovuta omwe amayenera kusunga kutentha kuti agwire ntchito.Mphamvu za nyukiliya za nyukiliya ndi mapampu a kutentha kwa mpweya omwe akuyembekezeka kugwiritsidwa ntchito kuthandizira mautumiki a Mwezi ndi Mars adzafunika kutengera kutentha kwapamwamba.

Gulu lofufuza lothandizidwa ndi NASA likupanga ukadaulo watsopano womwe "sadzangokwaniritsa kuwongolera kwakukulu pakutengera kutentha kuti zitheke kuti machitidwewa azikhala ndi kutentha koyenera mumlengalenga, komanso zithandizira kuchepetsa kukula ndi kulemera kwa hardware. .”

Izi zikumveka ngati chinthu chomwe chingakhale chothandiza kwa DC wamphamvu kwambirimalo opangira.

Gulu lotsogozedwa ndi Pulofesa wa Yunivesite ya Purdue, Issam Mudawar, apanga Flow Boiling and Condensation Experiment (FBCE) kuti athandizire kuyesa kwa magawo awiri amadzimadzi ndi kusamutsa kutentha kuchitidwe mu chilengedwe cha microgravity pa International Space Station.

Monga momwe NASA ikulongosolera: "FBCE's Flow Boiling Module imaphatikizapo zida zopangira kutentha zomwe zimayikidwa m'makoma a tchanelo momwe zimaperekera zoziziritsa kukhosi zitakhala madzimadzi.Zida zimenezi zikamatenthedwa, kutentha kwa madzi mumchenga kumawonjezeka, ndipo pamapeto pake madzi oyandikana ndi makomawo amayamba kuwira.Madzi otentha amapanga tinthu ting'onoting'ono pamakoma omwe amachoka pamakoma pafupipafupi, nthawi zonse amatulutsa madzi kuchokera mkati mwa njira yopita ku makoma a ngalande.Njira imeneyi imasamutsa kutentha bwino pogwiritsa ntchito mwayi wocheperako kutentha kwa madziwo komanso kusintha kwa kagawo kuchokera kumadzi kupita ku nthunzi.Izi zimatsitsimutsidwa kwambiri pamene madzi operekedwa ku njira ali mu subcooled state (ie bwino pansi pa kuwira).Izi zatsopanokuwira kwa subcoolednjira imapangitsa kuti kutentha kukhale kothandiza kwambiri poyerekeza ndi njira zina. ”

FBCE idaperekedwa ku ISS mu Ogasiti 2021, ndipo idayamba kupereka data yowira ya microgravity koyambirira kwa 2022.

 

Posachedwa, gulu la Mudawar lidagwiritsa ntchito mfundo zomwe adaphunzira kuchokera ku FBCE potengera njira yolipirira EV.Pogwiritsa ntchito ukadaulo watsopanowu, choziziritsa chamadzi cha dielectric (chosayendetsa) chimapopedwa kudzera pa chingwe cholipiritsa, pomwe chimatengera kutentha kopangidwa ndi kondakitala wonyamula pakali pano.Kutentha kocheperako komwe kunapangitsa kuti zidazo zichotse kutentha kwa 24.22 kW.Gululi likuti makina ake olipira amatha kupereka ma amps a 2,400.

Ndilo dongosolo lamphamvu kwambiri kuposa ma 350 kapena 400 kW omwe CCS yamphamvu kwambiri masiku ano.ma chargerchifukwa magalimoto onyamula anthu amatha kukwera.Ngati makina a FBCE-inspired charging angasonyezedwe pazamalonda, adzakhala m'gulu lomwelo ndi Megawatt Charging System, yomwe ndi mulingo wamphamvu kwambiri wa EV wacharging mpaka pano (umene tikuwudziwa).MCS idapangidwa kuti ikhale ndi mphamvu zokulirapo za 3,000 amps mpaka 1,250 V—yothekera 3,750 kW (3.75 MW) yamphamvu kwambiri.Pachionetsero mu June, chojambulira cha MCS chinatsika ndi MW imodzi.
