Aluminium feem ntau suav hais tias yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau cov dab dej kub. Vim nws cov thermal conductivity zoo dua, qhov hnyav qis, thiab pheej yig, nws yog qhov kev xaiv zoo rau ntau daim ntawv thov uas yuav tsum tau ua kom sov zoo.
Thaum tshav kub kub conductivity
Thermal conductivity yog ib qho ntawm cov tsis tseem ceeb uas txiav txim siab npaum li cas cov khoom siv hluav taws xob ua kom sov. Lub peev xwm ntawm cov khoom thauj mus rau tshav kub yog hu ua thermal conductivity. Nrog rau cov thermal conductivity ntawm ib ncig ntawm 205 W / m·K, txhuas yog ib yam khoom uas zoo absorbs thiab disperses cua sov los ntawm lub tshav kub qhov chaw.
Aluminium muaj qhov thermal conductivity tsawg dua li lwm cov hlau siv rau cov cua sov, xws li tooj liab (uas muaj thermal conductivity ntawm ib ncig ntawm 401 W / m·K). Nws lwm cov txiaj ntsig, suav nrog kev pheej yig thiab lub teeb yuag, feem ntau dhau qhov kev hloov pauv me me hauv cov hluav taws xob hluav taws xob.
Nature's Lightweight
Nrog rau qhov ceev ntawm ib ncig ntawm 2.7 g / cm³, txhuas yog lub teeb yuag hlau uas zoo meej rau kev siv qhov hnyav yog qhov teeb meem. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov haujlwm xws li electronics, automotive, thiab aerospace, qhov kev txo qhov hnyav yog qhov tseem ceeb rau kev txhim kho tag nrho cov kev ua tau zoo thiab kev siv hluav taws xob.
Vim tias txhuas yog lub teeb yuag, cov dab dej kub tuaj yeem siv tau thiab ntsia tau yooj yim dua, vim li ntawd cov kws tsim khoom thiab cov tuam txhab siv aluminium. Tsis tas li ntawd, aluminium kub dab dej 'qhov hnyav dua yuav ua rau pheej yig dua shipping thiab ntau dua system efficiency.
Nqi-zoo
Kev them taus ntawm txhuas raws li cov khoom siv cua sov yog lwm qhov txiaj ntsig. Aluminium yog pheej yig dua li lwm yam hlau nrog piv thermal conductivity zoo, xws li tooj liab los yog nyiaj, vim nws yog plentiful thiab nkag tau yooj yim.
Vim tias nws cov nqi pheej yig, aluminium yog cov khoom siv tau zoo rau kev siv loj thiab kev tsim khoom loj thaum cov nqi ntim khoom yog qhov kev txhawj xeeb tshaj plaws. Tsis tas li ntawd, aluminium heat sinks tej zaum yuav yog qhov kev xaiv pheej yig dua rau cov tuam txhab thiab cov tib neeg ntawm kev siv nyiaj nruj.
Kev tiv thaiv corrosion
Aluminium resists corrosion zoo vim yog nyias oxide txheej uas accumulates ntawm nws nto lawm. Los ntawm kev ua ib qho kev thaiv, cov oxide txheej no ua rau cov txhuas hauv qab ntawm kev cuam tshuam nrog ib puag ncig.
Cov ntawv thov, qhov twg lub dab dej kub tuaj yeem raug cov dej noo lossis lwm yam corrosive, tuaj yeem tau txais txiaj ntsig zoo tshaj plaws los ntawm qhov kev tiv thaiv corrosion. Nws lav lub dab dej kub ua haujlwm ntev thiab kev cia siab, ua rau nws ua haujlwm txuas ntxiv ntawm nws qhov kev ua haujlwm siab tshaj lub sijhawm. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov, txawm li cas los xij, cov txheej txheem tiv thaiv ntxiv tuaj yeem xav tau nyob rau hauv qee qhov kev ua phem, suav nrog kev lag luam lossis kev lag luam hauv hiav txwv, txhawm rau txhim kho corrosion ntawm aluminium kub dab dej.
Kev tsim tawm
Aluminium muaj ntau yam kev siv ntau yam thiab yooj yim rau kev tsim thiab pwm rau hauv ntau yam ntawm cov dab dej kub. Tej zaum nws yuav yog machined, cam khwb cia, los yog extruded los ntawm cov ntaub ntawv xav tau thiab cov khoom.
Kev ywj pheej tsim ntau dua yog ua tau los ntawm qhov yooj yim ntawm kev tsim khoom, tso cai rau cov engineers los tsim cov dab dej kub uas tau kho kom tau raws li cov ntawv thov tshwj xeeb 'kev xav tau thermal. Aluminium tej zaum yuav yooj yim tsim los ua kom tau raws li qhov xav tau ntawm ntau qhov kev lag luam thiab kev siv, txawm tias nws yog ib qho yooj yim finned tsim los yog sophisticated cua sov yeeb nkab layout.
Drawbacks ntawm Kub Sinks ua los ntawm Aluminium
Txawm hais tias txhuas muaj ntau yam txiaj ntsig raws li cov khoom siv hauv lub dab dej kub, nws tseem ceeb heev uas yuav tsum tau coj mus rau hauv tus account nws qhov tsis zoo thiab. Piv nrog rau lwm cov hlau, aluminium muaj qhov qis dua melting point, uas yog ib qho ntawm nws qhov tsis zoo. Vim nws qhov qis melting point ntawm 660 degrees Celsius, txhuas tej zaum yuav tsis haum rau siv nyob rau hauv cov xwm txheej uas yuav tsum tau ua hauj lwm kub ntau dua.
Tsis tas li ntawd, aluminium tsis muaj zog li cov khoom xws li hlau lossis tooj liab. Yog li, cov ntawv thov uas xav tau lub zog siv tshuab zoo lossis cov uas lub dab dej kub tuaj yeem raug cuam tshuam los ntawm kev vibrations lossis kev ntxhov siab ntawm lub cev tuaj yeem pom cov dab dej kub txhuas tsis zoo. Lwm cov ntaub ntawv uas muaj zog zoo tuaj yeem tsim nyog nyob rau qee qhov xwm txheej.
Hauv cov ntsiab lus
Nyob rau hauv xaus, aluminium lub superior thermal conductivity, lub teeb yuag tsim, affordability, muaj peev xwm tiv taus corrosion, thiab yooj yim ntawm kev tsim khoom ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov dab dej kub. Nws yog ib qho pheej yig, hloov tau qhov kev xaiv uas muab cov cua sov kom zoo.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account qhov kev xav tau tshwj xeeb ntawm txhua daim ntawv thov thiab tshuaj xyuas yog tias aluminium qhov tsis zoo-xws li nws qhov qis melting point thiab txo lub zog-yog qhov tsim nyog rau lub rhaub dej kub lub hom phiaj. Cov kws tshaj lij tuaj yeem txiav txim siab seb cov dab dej hauv aluminium puas tsim nyog rau lub kaw lus los ntawm kev ua tib zoo ntsuas cov khoom siv thiab cov thermal.
Vim tias lawv cov ntaub ntawv pov thawj ntawm kev tswj cov cua sov kom zoo thiab txhim kho kev ua haujlwm ntawm cov tshuab hluav taws xob thiab cov khoom siv, aluminium heat sinks tau siv ntau thiab suav nrog kev ntseeg siab thoob plaws ntau qhov chaw.
