Aluminium Extrusion Profiles Thaum tshav kub kub dab dej

Aluminium extruded heatsink

Aluminium extruded profiles kub dab dej tseem hu ua lub dab dej kub extrusion los yog extruded aluminium profiles kub dab dej.

Aluminium extrusion heat sink technology yog ua kom sov aluminium ingots mus rau 520 ~ 540 degree ntawm qhov kub thiab txias, nyob rau hauv siab siab kom cia cov kua txhuas ntws los ntawm lub dab dej kub extrusion pwm nrog grooves, ua rau cov khoom siv hluav taws xob extruded. Tom qab ntawd, tom qab txiav lub dab dej kub extrusion khoom, extruded aluminium kub dab dej peb feem ntau pom yog ua.

Aluminium extrusion heat sink technology yog ib qho yooj yim kom paub, thiab cov nqi ntawm cov cuab yeej siv kuj tsawg, yog li nws tau siv dav hauv kev lag luam qis hauv xyoo dhau los.

Vim li cas aluminium yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv cua sov?

Ua ntej, thermal conductivity yog qhov tseem ceeb tshaj plaws hauv kev xaiv cov khoom siv hluav taws xob, thiab cov khoom sib txawv muaj qhov sib txawv thermal conductivity.

Cov ntaub ntawv heatsink tuaj yeem yog pob zeb diamond, nyiaj, tooj liab, txhuas, hlau, thiab lwm yam. Koj tuaj yeem pom lawv cov thermal conductivity raws li hauv qab no:

Obviously, lub pob zeb diamond muaj zoo thermal conductivity. Pob zeb diamond tsis ua hluav taws xob thiab hluav taws xob tsis tuaj yeem txav mus los ywj pheej, yog li nws cov thermal conductivity yeej los ntawm kev nthuav tawm ntawm carbon atom vibrations (uas yog, phonons).

Vim yog qhov me me ntawm cov pa roj carbon atoms thiab muaj zog carbon-carbon daim ntawv cog lus, kev nthuav tawm ntawm kev co hauv pob zeb diamond yog du heev. Vim li no, thermal conductivity ntawm pob zeb diamond zoo heev, yuav luag siab tshaj plaws, thiab yuav luag 5 npaug ntawm cov nyiaj.

Pob zeb diamond tsis tsuas yog muaj ultra-siab thermal conductivity tab sis kuj yog cov khoom zoo heev, kho qhov muag, acoustic, hluav taws xob, thiab tshuaj lom neeg, uas ua rau nws zoo dua rau lwm cov ntaub ntawv nyob rau hauv cov nqe lus ntawm tshav kub dissipation ntawm high-power optoelectronic li.

Tau kawg, tus nqi ntawm pob zeb diamond yog kim heev, uas ua rau nws tsis yog cov khoom siv rau cov khoom siv heatsink.

Cov hlau uas muaj cua sov zoo tshaj plaws yog nyiaj, tab sis nws yog mos heev, uas tsis yog qhov tsim nyog rau kev tsim cov khoom siv high-density xws li cov dab dej kub.

Raws li cov hlau muaj txiaj ntsig, kub tsis yog cov khoom siv heatsink uas tsim nyog vim nws tus nqi kim. Cov khoom siv qis tshaj plaws yog hlau, tab sis nws cov thermal conductivity tsuas yog ib feem peb ntawm cov txhuas, uas tsis yog cov khoom siv heatsink.

Cov xwm txheej no tau coj mus rau tam sim no siv tooj liab lossis txhuas ua cov khoom siv hluav taws xob loj.

Tooj liab muaj thermal conductivity zoo dua li txhuas. Txawm li cas los xij, thaum xav txog thermal conductivity, tus nqi yog lwm yam uas tsis tuaj yeem tsis quav ntsej. Lub thermal conductivity ntawm tooj liab yog ob npaug ntawm txhuas, tab sis nws qhov ntom yog peb npaug ntawm txhuas. Qhov no txhais tau hais tias qhov hnyav ntawm lub dab dej kub uas muab cov cua sov zoo sib xws hauv tooj liab yuav nce li ntawm 50%.

Qhov tseeb, ntau lub dab dej kub tooj liab yog qhov hnyav tshaj qhov tsim txwv ntawm qhov hnyav. Thaum xam tus nqi ib tuj (tooj liab yog tam sim no kwv yees li 3.5 npaug ntawm tus nqi ntawm txhuas), thiab koj yuav pom tias tus nqi ntawm tooj liab yuav ntau dua li cov kev daws teeb meem ntawm txhuas rau tib lub dab dej kub tsim.

Dab tsi yog Aluminium Alloy Koj yuav tsum siv rau koj cov dab dej kub?

Lub thermal conductivity ntawm ntshiab txhuas yog 237 W / m•K, tab sis cov ntshiab txhuas yog cov mos mos hauv cov khoom siv kho tshuab, yog li alloy aluminium feem ntau yog siv los ua cov khoom siv heatsink.

Peb feem ntau yuav xub xav txog kev siv cov khoom siv nrog cov thermal conductivity, xws li 1050 txhuas, uas muaj cov nqi thermal conductivity ntawm 229 W / m•K. Txawm li cas los xij, cov hlau no yog mechanically mos heev rau cov dab dej kub.

Qhov kev xaiv zoo tshaj plaws yog 6000 series alloys rau cov dab dej kub. Cov alloys no muaj dav, muaj zog zoo, thiab zoo li extrude zoo. Daim duab hauv qab no qhia txog kev sib piv.

Alloys zoo li 6061 thiab 6063 yog qee qhov feem ntau hauv 6000 series. Lawv yog cov feem ntau rau extrusion feem ntau. Thiab ib qho yuav ua tau zoo heev rau cov dab dej kub.

Feature:

1. Muaj txiaj ntsig ntau dua li stamping kub dab dej

2. Cov nqi txuag ntau dua li kev ua tshuab

3. Muaj ntau hom qauv thiab ntau thiab tsawg

4. Yooj yim kho dua tooj liab sib dua, pom tseeb zoo

Dab tsi tsis yog koj xav tau los xaiv txoj cai extruded heat sink?

Thermal modeling: Thermal modeling yuav pab koj xaiv lub dab dej kub nrog kev ua tau zoo koj xav tau. Koj tuaj yeem siv computer software lossis nug koj tus neeg muag khoom rau kev ua qauv.

Khoom siv: Kub dab dej tuaj yeem ua los ntawm aluminium alloys. Cov khoom yuav tsum muaj siab thermal conductivity. Aluminium alloys feem ntau yog siv raws li lawv ruaj khov thiab muaj cov thermal zoo.

Fins: Fins tuaj yeem tuaj yeem sib txawv, cov duab, qhov loj thiab qhov chaw. Txhua qhov kev npaj tuaj yeem cuam tshuam kev ua haujlwm ntawm lub dab dej kub. Piv txwv li, flared pins muab thaj chaw loj dua rau cov cua sov kom dissipate.

Fin efficiency: Fins coj cov cua sov los ntawm lub cuab yeej thiab hloov mus rau huab cua lossis dej. Koj tuaj yeem nce qhov ua tau zoo ntawm fins hauv ntau txoj hauv kev. Piv txwv li, koj tuaj yeem nce qhov sib piv lossis txo qhov ntev ntawm cov fins.
