Kugwiritsa ntchito zida za SiC pamalo otentha kwambiri

Pazamlengalenga ndi zida zamagalimoto, zida zamagetsi nthawi zambiri zimagwira ntchito pakutentha kwambiri, monga injini zandege, injini zamagalimoto, zoyendera zamlengalenga zomwe zimayendera pafupi ndi dzuŵa, ndi zida zotentha kwambiri m'masetilaiti. Gwiritsani ntchito zida za Si kapena GaAs zomwe zimagwiritsidwa ntchito nthawi zonse, chifukwa sizigwira ntchito kutentha kwambiri, choncho zipangizozi ziyenera kuyikidwa pamalo otsika kutentha, pali njira ziwiri: imodzi ndiyo kuyika zipangizozi kutali ndi kutentha kwakukulu, ndiyeno kupyolera. amatsogolera ndi zolumikizira kuti alumikizane ndi chipangizo kuti chiziwongoleredwa; China ndi kuika zipangizozi m’bokosi lozizirirapo kenako n’kuziika pamalo otentha kwambiri. Mwachiwonekere, njira zonsezi zimawonjezera zida zowonjezera, kuwonjezera ubwino wa dongosolo, kuchepetsa malo omwe alipo ku dongosolo, ndikupanga dongosolo losadalirika. Mavutowa akhoza kuthetsedwa pogwiritsa ntchito mwachindunji zipangizo zomwe zimagwira ntchito kutentha kwambiri. SIC zipangizo akhoza opareshoni mwachindunji pa 3M - cail Y popanda kuzirala pa kutentha.

Zamagetsi za SiC ndi masensa zitha kukhazikitsidwa mkati ndi pamwamba pa injini za ndege zotentha ndikugwirabe ntchito pansi pazikhalidwe zowopsa izi, kuchepetsa kwambiri kuchuluka kwa dongosolo lonse ndikuwongolera kudalirika. Dongosolo la SIC-based distributed control system limatha kuthetsa 90% ya zowongolera ndi zolumikizira zomwe zimagwiritsidwa ntchito pamakina owongolera zishango zamakompyuta. Izi ndizofunikira chifukwa mavuto otsogolera ndi olumikizira ndi ena mwamavuto omwe amakumana nawo panthawi yopuma mu ndege zamasiku ano zamalonda.

Malingana ndi kuwunika kwa USAF, kugwiritsa ntchito zipangizo zamakono za SiC mu F-16 zidzachepetsa kulemera kwa ndege ndi mazana a kilogalamu, kupititsa patsogolo kayendetsedwe kake ndi mafuta, kuonjezera kudalirika kwa ntchito, ndikuchepetsa kwambiri mtengo wokonza ndi kuchepetsa nthawi. Mofananamo, magetsi a SiC ndi masensa amatha kupititsa patsogolo kayendetsedwe ka ndege zamalonda, ndi phindu lowonjezera lazachuma mu mamiliyoni a madola pa ndege iliyonse.

Momwemonso, kugwiritsa ntchito SiC kutentha kwambiri kwamagetsi zamagetsi ndi zamagetsi mu injini zamagalimoto kumathandizira kuyang'anira ndi kuwongolera kuyatsa bwino, zomwe zimapangitsa kuyaka koyera komanso kothandiza kwambiri. Komanso, makina oyendetsa magetsi a injini ya SiC amagwira bwino ntchito pamwamba pa 125 ° C, zomwe zimachepetsa chiwerengero cha otsogolera ndi zolumikizira mu chipinda cha injini ndikuwongolera kudalirika kwa nthawi yayitali kwa kayendetsedwe ka galimoto.

Masetilaiti amasiku ano amalonda amafuna ma radiator kuti athetse kutentha kopangidwa ndi zipangizo zamagetsi za m’mlengalenga, komanso zishango zoteteza zamagetsi za m’chombocho ku cheza cha mlengalenga. Kugwiritsa ntchito magetsi a SiC pa ndege kungachepetse kuchuluka kwa mayendedwe ndi zolumikizira komanso kukula ndi mtundu wa zishango zama radiation chifukwa zida zamagetsi za SiC sizingagwire ntchito pakutentha kwambiri, komanso kukhala ndi kukana kwamphamvu kwa matalikidwe-radiation. Ngati mtengo wotsegulira satellite kupita ku Earth orbit ukuyezedwa muunyinji, kuchepetsedwa kwakukulu pogwiritsa ntchito zida zamagetsi za SiC kumatha kupititsa patsogolo chuma komanso mpikisano wamakampani a satana.

Zombo zapamlengalenga zogwiritsa ntchito zida za SiC zolimbana ndi kutentha kwambiri zitha kugwiritsidwa ntchito pochita ntchito zovuta kwambiri kuzungulira dzuŵa. M'tsogolomu, pamene anthu adzachita utumwi mozungulira dzuwa ndi pamwamba pa mapulaneti mu dongosolo la dzuwa, zipangizo zamagetsi za SiC zokhala ndi kutentha kwambiri komanso kukana kwa radiation zidzagwira ntchito yofunika kwambiri kwa ndege zomwe zimagwira ntchito pafupi ndi dzuwa, kugwiritsa ntchito SiC electronic. zida zimatha kuchepetsa chitetezo cha ndege ndi zida zotayira kutentha, Chifukwa chake zida zambiri zasayansi zitha kuyikidwa mugalimoto iliyonse.
