Copper Heat Sink Fabrication

Taw qhia

Tooj tooj cua kub dab dej yog qhov tseem ceeb hauv kev ua kom cov khoom siv hluav taws xob niaj hnub txias, tshwj xeeb tshaj yog thaum cov khoom siv hluav taws xob pib kub thaum siv hnyav. Tib neeg xaiv tooj liab rau ib qho laj thawj yooj yim- nws txav tau cua sov zoo kawg. Peb tab tom tham txog thermal conductivity ze li ntawm 400 W / m•K, uas ua rau txoj kev tooj liab ua ntej ntawm txhuas thaum nws los rub cov cua sov tawm ntawm qhov kub. Tias yog vim li cas koj thiaj li pom tooj liab kub dab dej hauv txhua hom khoom siv: CPUs, GPUs, fais fab modules, thiab txawm tias LED systems.

Kev tsim cov dab dej kub no tsis yog ib qho - loj- haum- tag nrho cov txheej txheem, ib yam nkaus. Qee cov qauv tsim tau yooj yim zoo nkauj, thaum lwm tus tau txais kev zoo nkauj, nyob ntawm seb lub gadget xav tau dab tsi thiab nws tuaj yeem raug nqi npaum li cas. Raws li kev siv thev naus laus zis zuj zus thiab lub zog nce ntxiv, qhov xav tau kom ntseeg tau qhov txias txias cia li loj hlob tuaj. Ua siab ncaj, yog tias koj tab tom nrhiav khoom, ntev - kev ua haujlwm ntev, tooj liab kub dab dej yog qhov nyuaj.

Material Properties thiab Design Considerations

Yog tias koj xav tau lub dab dej tooj liab kom ua haujlwm tau zoo, koj yuav tsum tau txais dab tsi ua rau tooj liab zuam - thiab tsim nrog cov cwj pwm hauv siab. Tseeb, tooj liab zoo heev ntawm rub tawm cua sov, nws shrugs tawm corrosion, thiab nws yog tawv txaus kom kav ntev. Kev lag luam - tawm? Nws hnyav dua thiab raug nqi ntau dua li txhuas. Yog li engineers yuav tsum juggle: ntau npaum li cas thermal kev ua tau zoo tsim nyog qhov hnyav thiab tus nqi?

Cov ntsiab lus tseem ceeb ntawm no. Tej yam zoo li nruj npaum li cas koj ntim cov fins, tuab npaum li cas koj ua lub hauv paus, tag nrho thaj chaw saum npoo av, thiab koj tswj cov huab cua ua rau qhov sib txawv loj. Muab cov fins ze dhau lawm? Koj yuav txav cua sov, tab sis choke lub airflow. Tshaj tawm lawv? Cua glides los ntawm, tab sis koj yuav poob ib co cua txias punch.

Tseem muaj tooj liab softness. Nws ua rau cov hlau yooj yim rau kev tswj hwm, tab sis khoov nws tsis ncaj ncees lawm thaum tsim khoom thiab koj yuav ua rau tag nrho cov qauv tsim. Vim tias tag nrho cov khoom txav no, feem ntau cov neeg tsim qauv siv simulation software los sim thiab tweak lawv cov tswv yim ua ntej ua rau qhov tseeb. Nws yeej kho qhov yuam kev kim tom qab qhov tseeb.

Kev tsim cov txheej txheem rau Copper Heat Sinks

Skiving Fin txheej txheem
Nrog rau cov txheej txheem skiving, koj hlais ultra- nyias fins ncaj nraim tawm ntawm cov khoom siv tooj liab siv lub tshuab txiav. Qhov tshwm sim? Fins thiab hauv paus yog tag nrho ib thooj - tsis muaj kua nplaum los yog pob qij txha - yog li cov cua sov txav mus los ntawm super ceev. Qhov no ua haujlwm zoo rau siab - cov tshuab ua haujlwm uas xav tau ntau cov fins ntim ze ua ke kom tshem tawm cov cua sov sai.

Bonded Fin txheej txheem
Rau kev sib raug zoo fins, koj txuas ib tus neeg tooj liab fins rau lub hauv paus phaj siv cov kua nplaum los yog los ntawm kev sib tsoo. Cov txheej txheem no muab ntau txoj kev xaiv rau koj-koj tuaj yeem tweak qhov chaw nruab nrab ntawm cov fins lossis ua kom lawv siab zoo nkauj yooj yim. Nws yog zoo meej rau cov hauj lwm kev cai. Kev ntes yog, ib txwm muaj me me ntawm thermal kuj qhov twg cov fins ntsib lub hauv paus, yog li nws tsis txias heev li zoo li lub dab dej kub skived.

Folded Fin txheej txheem
Folded fins yog ib hom tsiaj sib txawv. Koj muab cov ntawv nyias nyias, quav lawv rau hauv cov duab, thiab tom qab ntawd kho cov ntawd rau hauv lub hauv paus phaj. Qhov no ua rau cov dab dej kub nrog rau thaj chaw loj loj uas yog qhov hnyav zoo nkauj. Nws yog tus nqi pheej yig thiab ua rau muaj qhov sib npaug zoo rau nruab nrab - cov ntawv thov ntau, txawm hais tias nws tsis ua kom muaj cua sov zoo li kev siv skiving lossis machining txoj kev.

Stamping txheej txheem
Stamping yog yooj yim heev. Koj nias cov nplooj ntawv tooj liab rau hauv cov duab uas siv qhov tuag thiab ntau lub zog. Txoj hauv kev no ci ntsa iab hauv kev tsim khoom loj-xav ntau cov dab dej kub yooj yim, txhua yam zoo ib yam. Nws yog ceev thiab pheej yig, tab sis tsis zoo rau cov duab nyuaj lossis cov ntaub ntawv tuab.

Txheej txheem Forging
Forged heat sinks tau txais lawv cov duab thaum rhuab tooj liab yog jammed rau hauv pwm nrog hnyav siab. Qhov no ua kom nruj rau cov qauv tooj liab, ua rau nws tawv dua thiab muab kev ua haujlwm zoo thermal. Nws yog qhov kev xaiv ntse rau rugged, siab - txhim kho kev ntseeg tau. Qhov downside? Ua cov cuab yeej raug nqi ntau dua, thiab koj tsis tau txais kev ywj pheej ntau npaum li kev xaiv tsim.

CNC Machining txheej txheem
CNC machining yog txhua yam hais txog precision. Khoos phib tawj-cov cuab yeej qhia tau kos cov duab kos raws li koj tus qauv tsim. Koj tuaj yeem tau txais kev muaj tswv yim zoo nrog qhov no - cov duab nyuaj, cov ntsiab lus tsis sib xws, nruj kam rau ua- txhua yam ua tau. Nws yog qhov mus- rau cov qauv lossis cov khoom siv cua sov. Koj ua tiav nrog ntau cov khoom pov tseg thiab cov nqi siab dua piv rau lwm txoj hauv kev, tab sis rau qee txoj haujlwm, qhov tseeb yog tsim nyog.

Kev kho deg thiab kev ua tau zoo

Kev kho deg tseem ceeb heev thaum koj ua tooj liab kub dab dej. Nws yog qhov ua rau lawv nyob ntev dua thiab ua lawv txoj haujlwm zoo dua. Koj yuav pom nickel plating, tin txheej, thiab passivation siv zoo nkauj heev. Ntawm cov no, nickel plating sawv tawm. Nws ua haujlwm zoo ntawm kev txwv cov tooj liab los ntawm oxidizing thiab tiv thaiv corrosion, tag nrho tsis messing nrog cov cua kub zoo li cas los ntawm cov hlau. Thiab yog tias tooj liab oxidizes, nws tsuas yog tsis hloov cua sov ib yam nkaus, yog li koj xav kom zam qhov ntawd. Cov tib neeg kuj xyuam xim rau qhov chaw ntxhib npaum li cas, vim tias qhov ua tiav smoother pab tooj liab haum zoo dua rau lwm yam khoom siv hluav taws xob, ua kom kub hloov tau zoo dua.

Nyob rau sab saum toj ntawm qhov ntawd, cov ntaub ntawv thermal interface- cov pastes lossis cov ntaub qhwv - feem ntau mus nruab nrab ntawm lub dab dej kub thiab cov nti kom txo qis kev tiv thaiv kev tiv thaiv ntxiv. Muaj ntau qhov kev tsim kho tshiab tshwm sim, thiab. Cov txheej txheem txheej txheem tau tsim los txhawb emissivity, uas txhais tau hais tias lub dab dej kub tuaj yeem tshem tawm cov cua sov los ntawm hluav taws xob ntau dua, tshwj xeeb tshaj yog nyob rau hauv qee yam khoom siv.

Daim ntawv thov thiab yav tom ntej Trends hauv Copper Heat Sink Fabrication

Koj yuav pom tooj liab kub dab dej nyob txhua qhov chaw - los ntawm smartphones thiab laptops mus rau telecom iav, tsheb, thiab txawm lub hnub ci vaj huam sib luag. High- cov khoos phis tawj ua tau zoo, tshwj xeeb tshaj yog nyob ntawm cov tooj liab no txhawm rau ua kom muaj cua sov ntxiv thaum lawv muaj zog dua. Hauv tsheb hluav taws xob, tooj liab kub dab dej ua lub luag haujlwm tseem ceeb hauv kev tswj roj teeb thiab hluav taws xob hluav taws xob, pab txhua yam ua haujlwm zoo thiab ua haujlwm zoo.

Saib ua ntej, txoj kev uas peb ua tooj liab kub dab dej yog hloov ceev. Cov txheej txheem tsim khoom tshiab xws li 3D luam ntawv thiab cov txheej txheem hybrid cia cov engineers tsim ntau cov duab uas ua kom txias zoo dua thiab khib nyiab tsawg dua. Raws li txhua yam los ntawm cov khoos phis tawj mus rau EVs tau kub dua thiab muaj zog dua, kev tswj xyuas cov cua sov ntse tseem ceeb dua li ib txwm muaj - thiab tooj liab cua sov yuav ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob tag kis.
