Rolled aluminium fin khoom feem ntau muaj cov tuab tuab thiab haum rau qee qhov xwm txheej uas yuav tsum tau tiv taus siab dua lossis hnyav dua., xws li kev tsim kho, tsheb, machinery thiab lwm yam kev lag luam. Cov ntaub ntawv zoo li aluminium fin khoom yog nyias nyias thiab muaj cov thermal conductivity thiab electromagnetic shielding zog, yog li nws feem ntau siv hauv electronics, kev sib txuas lus, aerospace thiab lwm yam.
Aluminium fins feem ntau yog siv los ua cov khoom tseem ceeb hauv cov khoom siv hluav taws xob, tub yees, thiab automotive cua txias tshuab uas tso siab rau aluminium fins kom ua kom sov siab tshaj plaws. Kev xaiv ntawm aluminium alloys rau cov fins yog qhov tseem ceeb vim yog cov kev cai tshwj xeeb rau lub zog, corrosion kuj, thermal conductivity, thiab formability.
Aluminium yog dav xaiv rau fins vim nws cov thermal conductivity zoo heev, corrosion kuj, kev kaj, thiab tus nqi-zoo. Nyob rau hauv tshav kub exchangers, aluminium fins txhim khu cov cua kub dissipation los ntawm kev nce qhov chaw saum npoo muaj rau kev sib pauv cua sov. Kev xaiv ntawm aluminium alloy nyob ntawm ntau yam
Thermal conductivity: High thermal conductivity ua kom muaj kev hloov pauv hluav taws xob zoo. Corrosion kuj: Extens lub neej kev pab, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej lossis tshuaj lom neeg nruj heev. Mechanical zog: Lub zog txaus thiab kav ntev yog tsim nyog los tiv thaiv kev ntxhov siab ntawm cov neeg kho tshuab. Formability: Cov hlau yuav tsum txhawb nqa cov ntawv ci nyias thiab cov duab nyuaj yam tsis muaj kev tawg. Nqi-zoo: Hauv cov ntawv thov loj, kev xaiv nyiaj txiag feem ntau nyiam.
Muaj ntau ntau aluminium alloys feem ntau siv rau cov ntawv ci thiab fin daim ntaub ntawv. Cov alloys no feem ntau yog los ntawm cov 1000, 3000, thiab 8000 series:
Kev sib xyaw thiab cov khoom: Cov 1000 series yog ze li ntawm ntshiab txhuas, nrog dhau 99% cov ntsiab lus aluminium. Alloys xws li 1050, 1060, thiab 1100 yog dav siv rau lawv zoo heev thermal thiab hluav taws xob conductivity. Qhov zoo: High Thermal conductivity: Ze li ntawm cov ntshiab aluminium muaj thermal conductivity zoo heev, uas yog qhov tseem ceeb rau kev hloov cov cua sov kom zoo. Corrosion Resistance: High purity ua kom muaj zog tiv thaiv corrosion. Formability: Cov alloys no tsis tshua muaj ductile thiab haum rau nyias foils. Qhov tsis zoo: Tsawg zog: Cov alloys no muaj cov neeg kho tshuab tsis tshua muaj zog thiab tsis haum rau cov ntawv thov kev ntxhov siab. Txwv tsis pub hnav tsis kam: Ntshiab aluminium yog mos thiab raug hnav. Daim ntawv thov: 1000 series alloys feem ntau yog siv hauv cov cua txias, radiators, thiab evaporators, uas yuav tsum tau high thermal efficiency thiab tsawg zog.
Kev sib xyaw thiab cov khoom: Cov 3000 series muaj xws li alloys xws li 3003, 3102, thiab 3104, nrog manganese ua lub ntsiab alloying. Qhov zoo: Lub zog nruab nrab: Manganese txhim kho txhua yam khoom piv rau cov 1000 series. Corrosion Resistance: Zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig humid los yog ntsev. Zoo thermal conductivity: Tsim nyog cov khoom siv thermal rau feem ntau cov cua sov sib pauv tshuab. Qhov tsis zoo: Thermal conductivity me ntsis: Me ntsis thermal conductivity piv rau cov 1000 series vim alloying ntsiab. Tus nqi siab dua: Lub xub ntiag ntawm cov ntsiab lus alloying nce cov nqi khoom. Daim ntawv thov: Feem ntau siv nyob rau hauv automotive tshav kub exchangers, tub yees tshuab, thiab cua txias fins, qhov twg yuav tsum muaj qhov sib npaug ntawm lub zog thiab conductivity.
Kev sib xyaw thiab cov khoom: 8000 series alloys (xws li 8011 thiab 8079) muaj me me ntawm cov hlau thiab silicon. Cov alloys no feem ntau siv rau kev ntim khoom thiab cov ntawv ci, tab sis kuj tuaj yeem siv rau hauv kev tsim khoom fin. Qhov zoo: Zoo thermal conductivity: Ntxiv cov hlau thiab silicon optimize conductivity thiab lub zog. Siab corrosion kuj: Haum rau qhov nyuaj ib puag ncig. Zoo heev formability: Tso cai rau kev tsim cov ntawv nyias nyias. Qhov tsis zoo: Lub zog nruab nrab: Cov alloys no tsis muaj zog li cov 3000 series alloys. Daim ntawv thov: Siv nyob rau hauv industrial tshav kub exchangers thiab HVAC systems.
8011 aluminium alloy yog ib qho kev xaiv rau cov cua kub exchanger fin blanks, tshwj xeeb tshaj yog rau cov cua txias thiab tub yees. Nws yog aluminium-hlau-silicon alloy nrog zoo corrosion kuj thiab formability.
