Vim li cas Aluminium Dominates Computer Enclosures
Computer manufacturers choose aluminum sheet for casings, panels and heat-management components because it combines low density, good thermal conductivity, high stiffness per unit weight and a premium surface finish. Lub thawv hlau tseem thaiv cov khoom siv hluav taws xob sab hauv los ntawm kev cuam tshuam electromagnetic zoo dua li cov yas. Cov khoom no tso cai rau cov neeg tsim qauv tsim cov khoom siv nyias, lub teeb, nruj uas ua rau cov cua sov ntawm cov txheej txheem niaj hnub tsis muaj cov khoom siv txias txias.
Alloy xaiv rau Computer Parts
Feem ntau cov alloys yog 5052 thiab 6061. 5052 daim ntawv zoo rau stamped thiab bent casings, resists corrosion thiab anodizes rau ib tug txawm xim, uas yog vim li cas nws yog standard rau unibody -style enclosures thiab panels. 6061 nyob rau hauv lub T6 temper muab siab zog rau CNC-machining thav duab, thiab cov keyboards 6} decks. ncej thiab rails. Ntshiab 1xxx alloys tshwm nyob rau hauv tshav kub- cov ntawv nthuav tawm qhov siab tshaj plaws thermal conductivity thiab lub zog yog qhov thib ob.
Thermal Management
Lub thermal conductivity ntawm txhuas alloys nyob ntawm kwv yees li 140 txog 230 W ib meter ib kelvin nyob ntawm cov hlau, nrog 6061 ntawm li 167 thiab ntshiab txhuas siab tshaj 200. Daim ntawv thiab phaj yog machined los yog stamped rau hauv cov dab dej kub, vapor{5}}chamber npog thiab cua sov- tawm ntawm cov kiv cua los yog GPU. Vim hais tias lub casing nws tus kheej ua raws li lub tshav kub exchanger, nyias txhuas vaj huam sib luag yuav tsum tau tsim kom muaj kev sib cuag nto thiab airflow paths.
Nto Finishing
Anodizing yog kos npe tiav ntawm cov ntaub ntawv hauv computer: nws ua kom tawv nqaij, tiv thaiv cov ntiv tes, thiab ua kom pom tseeb, xim dub, nyiaj thiab qhov chaw - xim grey pom ntawm cov khoom siv zoo tshaj. Txhuam ua ntej anodizing tsim cov kab zoo nkauj zoo nkauj ntawm lub laptop hau, thaum sandblasting muab qhov muag muag muag. PVD thiab xim tshuab yog siv rau cov xim tshwj xeeb. Kev tswj kev kam rau siab thaum tsim thiab ua haujlwm, feem ntau nyob rau hauv qhov ntau ntawm ntxiv lossis rho tawm 0.05 mus rau 0.1 hli rau cov khoom sib dhos, yog qhov tseem ceeb rau qhov sib txawv thiab qhov dej ntws tawm.
Cov txheej txheem Fabrication
Enclosure qhov chaw yog tsim los ntawm stamping, dabtsi yog khoov, CNC milling, laser txiav thiab nto tiav nyob rau hauv ib theem zuj zus. Daim ntawv thickness feem ntau yog 0.8 mus rau 1.5 hli rau panels thiab 2 mus rau 4 hli rau machined ntas. Tight tolerances yuav tsum muaj kev ntxhov siab-cov khoom siv tau yooj yim thiab ua tib zoo tsim kho kom zoo, vim tias nyias aluminium yog qhov nkag mus rau qhov seem ntawm kev ntxhov siab thiab clamping distortion. Ntug kev kho mob, suav nrog chamfering thiab polishing, tiv thaiv cov ces kaum ntse thiab txhim kho qhov pom zoo ntawm cov khoom tiav.
FAQ
Q: Vim li cas lub laptops siv txhuas es tsis txhob yas?
A: Txhuas muab cov cua kub zoo dua, kev nruj dua ntawm cov phab ntsa nyias nyias, kev xav zoo siab thiab ntuj EMI shielding, uas ua rau nws tus nqi siab dua rau cov khoom siv hwm.
Q: Dab tsi alloy yog siv rau anodized laptop lub cev?
A: 5052 yog qhov ntau tshaj plaws rau lub cev stamped vim nws ua tau zoo thiab anodizes uniformly . 6061 yog siv qhov twg CNC machining thiab siab zog yuav tsum tau.
Q: Puas yog anodizing txo thermal kev ua haujlwm?
A: Cov zaj duab xis anodic yog nyias thiab muaj kev cuam tshuam me me ntawm kev ua los ntawm cov hlau. Nws cov nyhuv loj dua yog nyob rau saum npoo emissivity, uas tuaj yeem pab tau hluav taws xob kub ntawm lub casing.
Q: Cov ntawv txhuas puas tuaj yeem siv rau cov dab dej kub?
A: Yog. Ntshiab aluminium thiab 6061 daim ntawv yog skived, stamped los yog machined rau hauv cov dab dej kub thiab cov hluav taws kub, nrog rau kev ua haujlwm thermal nyob ntawm cov hlau thiab cov fin tsim.
Q: Yuav ua li cas yog cov txhuam hniav zoo nkauj ua ntej anodizing?
A: Ib txoj siv tawv los yog lub tshuab txhuam hniav tsim ib qho kev coj ua zoo rau ntawm daim ntawv, thiab ib feem yog tom qab ntawd degreased, etched thiab anodized kom cov kev ntxhib los mos yog khaws cia hauv cov yeeb yaj kiab anodic.
