Kugwiritsa ntchito zipangizo za SiC pamalo otentha kwambiri

Mu zida zapamlengalenga ndi zamagalimoto, zamagetsi nthawi zambiri zimagwira ntchito kutentha kwambiri, monga mainjini a ndege, mainjini a magalimoto, zombo zamlengalenga zomwe zimagwira ntchito pafupi ndi dzuwa, ndi zida zotentha kwambiri m'ma satellite. Gwiritsani ntchito zida za Si kapena GaAs zomwe zimagwiritsidwa ntchito nthawi zonse, chifukwa sizigwira ntchito kutentha kwambiri, kotero zida izi ziyenera kuyikidwa pamalo otentha kwambiri, pali njira ziwiri: imodzi ndikuyika zida izi kutali ndi kutentha kwakukulu, kenako kudzera mu ma lead ndi zolumikizira kuti mulumikizane ndi chipangizocho kuti chiwongoleredwe; Ina ndikuyika zida izi m'bokosi loziziritsira kenako ndikuziyika pamalo otentha kwambiri. Mwachionekere, njira zonsezi zimawonjezera zida zina, zimawonjezera ubwino wa makinawo, zimachepetsa malo omwe alipo pamakinawo, ndikupangitsa makinawo kukhala osadalirika. Mavutowa amatha kuthetsedwa pogwiritsa ntchito zida zomwe zimagwira ntchito kutentha kwambiri. Zipangizo za SIC zitha kugwiritsidwa ntchito mwachindunji pa 3M - cail Y popanda kuzizira kutentha kwambiri.

Zida zamagetsi ndi masensa a SiC amatha kuyikidwa mkati ndi pamwamba pa injini za ndege zotentha ndipo amagwirabe ntchito pansi pa mikhalidwe yovuta kwambiri yogwirira ntchito, zomwe zimachepetsa kwambiri kulemera kwa makina onse ndikuwonjezera kudalirika. Dongosolo lowongolera logawidwa lochokera ku SIC limatha kuchotsa 90% ya ma lead ndi zolumikizira zomwe zimagwiritsidwa ntchito mumakina olamulira zishango zamagetsi. Izi ndizofunikira chifukwa mavuto a lead ndi zolumikizira ndi ena mwa mavuto omwe amakumana nawo nthawi yogwira ntchito m'ndege zamalonda zamasiku ano.

Malinga ndi kuwunika kwa USAF, kugwiritsa ntchito zida zamagetsi zapamwamba za SiC mu F-16 kudzachepetsa kulemera kwa ndege ndi ma kilogalamu mazana ambiri, kukweza magwiridwe antchito ndi kugwiritsa ntchito bwino mafuta, kuonjezera kudalirika kwa ntchito, ndikuchepetsa kwambiri ndalama zokonzera ndi nthawi yopuma. Mofananamo, zida zamagetsi za SiC ndi masensa zitha kukonza magwiridwe antchito a ndege zamalonda, ndi phindu lina lazachuma lomwe lanenedwa kuti lidzakhala mamiliyoni a madola pa ndege iliyonse.

Mofananamo, kugwiritsa ntchito masensa amagetsi ndi zamagetsi a SiC otentha kwambiri m'mainjini a magalimoto kudzathandiza kuyang'anira bwino kuyaka ndi kuwongolera, zomwe zimapangitsa kuyaka kukhala koyera komanso kogwira mtima. Kuphatikiza apo, makina owongolera zamagetsi a injini ya SiC amagwira ntchito bwino kuposa 125°C, zomwe zimachepetsa kuchuluka kwa ma lead ndi zolumikizira m'chipinda cha injini ndikuwonjezera kudalirika kwa nthawi yayitali kwa makina owongolera magalimoto.

Ma satellite amalonda a masiku ano amafuna ma radiator kuti achotse kutentha komwe kumapangidwa ndi zamagetsi a chombocho, ndi zishango kuti ateteze zamagetsi a chombocho ku kuwala kwa mlengalenga. Kugwiritsa ntchito magetsi a SiC pa chombocho kungachepetse kuchuluka kwa ma lead ndi zolumikizira komanso kukula ndi mtundu wa zishango za kuwala chifukwa magetsi a SiC sangagwire ntchito kutentha kwambiri kokha, komanso amakhala ndi mphamvu yolimbana ndi kuwala kwa amplitude. Ngati mtengo woyambitsa satelayiti mu Earth orbit uyesedwa mu kulemera, kuchepetsa kulemera pogwiritsa ntchito magetsi a SiC kungapangitse kuti makampani a satelayiti akhale ndi chuma komanso mpikisano.

Zombo za mumlengalenga zomwe zimagwiritsa ntchito zipangizo za SiC zopirira kutentha kwambiri zitha kugwiritsidwa ntchito pochita ntchito zovuta kwambiri kuzungulira dongosolo la dzuwa. M'tsogolomu, anthu akamachita ntchito mozungulira dzuwa ndi pamwamba pa mapulaneti omwe ali mu dongosolo la dzuwa, zipangizo zamagetsi za SiC zomwe zili ndi mphamvu zabwino kwambiri zotsutsana ndi kutentha kwambiri komanso kukana kwa kuwala zidzakhala ndi gawo lofunika kwambiri pa zombo za mumlengalenga zomwe zimagwira ntchito pafupi ndi dzuwa, kugwiritsa ntchito zipangizo zamagetsi za SiC kungachepetse chitetezo cha zombo za mumlengalenga ndi zida zochotsera kutentha, kotero zida zambiri zasayansi zitha kuyikidwa mu galimoto iliyonse.
