Aluminium siv yog yam tsis muaj nyob rau hauv maximized EV lub teeb.
NEV tam sim no tau nyob rau hauv ib qho kev loj hlob sai, tshwj xeeb tshaj yog nyob rau hauv Tuam Tshoj, UK, Fabkis thiab Norway. Hauv lub tebchaws no, EV thiab Hybrid Tsheb muaj ntau pom ntawm txoj kev. Ford, GE, JAGUAR, Volkswagen, Volvo tam sim no tau tshaj tawm lawv EV's Plan.
Aluminium siv yog yam tsis muaj nyob rau hauv maximized EV lub teeb. Hais txog lub teeb yuag, tag nrho cov txheej txheem yog siv aluminium alloy nyob rau hauv cov xwm txheej ntawm kev ua raws li kev ruaj ntseg cov cai thiab cov cuab yeej technology. Txawm li cas los xij, Magnesium lossis lwm yam khoom siv sib xyaw kuj muaj peev xwm ncav cuag lub hom phiaj ntawm lub teeb yuag. Tab sis nyob rau hauv cov nqe lus ntawm kev sib koom ua yeeb yam thiab tus nqi zoo, aluminium alloy tseem yog cov kev xaiv zoo tshaj plaws, thiab tus ntoo khaub lig piv ntawm txhuas nrog lwm cov khoom siv tseem niaj hnub.
1 EV thiab nws cov txhuas extrusion thov
EU tau hais tias, CO2 emission yuav tsum tau nyob rau hauv 2050, feem ntau ntawm cov tsheb tam sim no alloyed siv fossil fuels. Hauv qhov xwm txheej no, txog 2050, 80% ntawm cov tsheb hauv Tebchaws Europe yuav tsum yog hluav taws xob. Txhawm rau kom ncav cuag lub hom phiaj no, EV muag ntawm cov tsheb yuav tsum nce mus txog 50%. Kev hloov tsheb kev lag luam rau EV tsis yog qhov xav tau lossis cov lus qhia, nws yog qhov tsim nyog. Tuam Tshoj, Tebchaws Europe thiab Tebchaws Asmeskas tam sim no tau ua luam dej nrog cov dej ntws, nws tsis yog qhib kev tsim kho tshiab xwb tab sis kuj suav nrog kev tsim khoom.
Nyob rau hauv qhov kev ncua deb mus txawv tebchaws, lub zog noj yog sib npaug rau EV's Curb Vehicle Weight, uas kuj txhais tau tias qis dua CVW yog qhov tsim nyog. Los ntawm txo cov roj teeb rooj plaub thiab tag nrho CVW, nws raug nquahu kom siv aluminium extrusion.
Tsis ntev los no, CRU tau nqa cov kev tshawb fawb thiab kev kwv yees ntawm qhov kev thov rau txhuas extrusion EV lub cev thiab cov qauv tsim. Nws tau xaus lus tias txog 2030, thoob ntiaj teb kev thov yog nyob ib ncig ntawm 10 lab metric tons. Qhov piv ntawm ob qho txhuas extrusion yog 80% txhuas daim hlau ntxiv rau 20% ntawm txhuas seem. Hauv lwm lo lus, aluminium seem kom muaj nuj nqis yuav yog 2 lab metric tons. Hauv EV, lub cev qauv tseem ceeb muaj nyob ib ncig ntawm 10-11% ntawm cov ntu txhuas.
2 Aluminium extrusion alloy hauv EV daim ntawv thov.
2.1 Roj teeb rooj plaub thiab parapets
Rau cov ntaub ntawv roj teeb, cov khoom siv yuav tsum ua kom zoo thiab siv tau zoo. Tam sim no, txhuas yog qhov kev xaiv zoo tshaj plaws, uas zoo dua li cov hlau hlau thiab CFRP.
Yuav luag txhua lub tuam txhab tsheb tau siv txhuas extrusion rau cov ntaub ntawv roj teeb, xws li BMW, Audi, Volvo. Lub sijhawm ntawd, qee cov tuam txhab tau nthuav tawm kev txaus siab rau Tesla CTC thev naus laus zis thiab pib xyaum, xws li i20 EV los ntawm BMW, e-tron los ntawm Audi, EQ los ntawm Mercedes. Keeb kwm, Audi siv aluminium casting alloy rau cov ntaub ntawv roj teeb, thiab tam sim no tau hloov mus rau aluminium extrusion nrog rau BEVs thiab PHEVs.
2.2 Aluminium tuab daim hlau txias rooj plaub
Xyoo 2018, Constelium thawj zaug tau tsim cov qauv tshiab ntawm cov ntaub ntawv roj teeb hu ua 'Cooling Aluminium', uas muaj kev ua tau zoo ntawm kev ua kom txias. Los ntawm kev siv cov qauv no, tsis tas yuav rub txoj hlua vuam txuas. Cov txiaj ntsig tau hais tias, cov ntawv txias txias nruj txuas nrog tsis muaj qhov xau thiab teeb tsa yooj yim. Thaum lub sij hawm sim, nws tau pom qhov ua tau zoo txias txias, thiab qhov sib txawv ntawm qhov kub yog ± 2 ℃. Nws txuas lub roj teeb siv lub neej thiab ua kom muaj kev nyab xeeb. Case cov khoom seem yog khoov txhuas extrusion tsis muaj qhov punch, vuam, thiab tag nrho qhov hnyav yog 15% tsawg dua ua ntej.
Los ntawm kev txhim kho cov khoom siv aluminium innovation, tsheb-siv txhuas thiab EV yog complementary ntawm ib leeg thiab sustainably tsim ua ke. Lub sijhawm ntawd, xoom kuab paug yuav yog qhov tshwm sim tiag tiag nyob ze yav tom ntej.
