Taw qhia
Niaj hnub no, kev tsim lub dab dej kub yuav tsum ua raws li cov khoom siv hluav taws xob uas ua kom me me tab sis xav tau ntau lub zog. Nws tsis muaj teeb meem yog tias nws yog lub xov tooj smartphone lossis ib qho ntawm cov cuab yeej ua haujlwm hnyav - tswj kev thermal zoo yog qhov ua rau lawv khiav nyab xeeb thiab ntau xyoo. Kev ntim cov cua txias kom zoo rau hauv qhov chaw me me tsis yooj yim. Koj yuav tsum tau nyem tawm cov cua sov kom ntau li ntau tau yam tsis ua kom lub dab dej kub ua kom loj lossis kim los tsim. Muaj ib txwm ntsuas qhov ntsuas no: sim ua kom haum rau hauv thaj chaw ntau dua kom ua kom txias dua, ua kom huab cua txav mus, tab sis tsis txhob tshuab qhov loj lossis qhov hnyav. Thiab koj tsis tuaj yeem tsis quav ntsej tag nrho cov duab tshwj xeeb, lub zog siab ntom ntom, lossis qhov chaw tsis paub tseeb uas cov khoom siv no nkag mus.
Saib cov khoom xws li CPUs, GPUs, LEDs niaj hnub, thiab lwm yam khoom siv hluav taws xob hluav taws xob-lawv cia li thawb cov txwv, tso tawm cua sov ntau dua hauv qhov chaw tsawg dua. Qhov ntawd yog qhov uas ntse, compact heat sinks tiag tiag qhia lawv tus nqi thiab khaws txhua yam ntawm qhov kub thiab txias. Yog tias koj tsis muaj qhov zoo ntawm kev hloov pauv hauv cov cua sov los yog tsis xaiv cov ntaub ntawv kom zoo, koj tus qauv yuav poob qis. Nws yog txhua yam hais txog kev nkag siab txog cov hauv paus ntsiab lus thiab kev txwv kom tau txais cov khoom siv hluav taws xob sib txuas uas ua haujlwm tau zoo.
Cov Ntsiab Cai Tsim Nyog rau Cov Cuab Yeej Siv Hluav Taws Xob
Thaum koj tab tom tsim ib lub dab dej kom sov, koj tab tom ua haujlwm nrog peb txoj kev tawm cua sov: conduction, convection, thiab hluav taws xob. Ua ntej, conduction txav cua sov los ntawm koj qhov chaw-zoo li lub nti- ncaj nraim rau hauv lub dab dej kub lub hauv paus. Tom ntej no, convection ua haujlwm feem ntau ntawm kev ua haujlwm, thawb lub cua sov tawm mus rau saum huab cua. Radiation NW nyuam qhuav tseem ceeb tshwj tsis yog tej yam kub heev.
Txhawm rau ua kom lub dab dej ua kom sov ua haujlwm tiag tiag, koj yuav tsum ua kom cov cua sov tau yooj yim los ntawm qhov chaw mus rau fins, yog li txo qis hauv cov kev ua haujlwm yog qhov tseem ceeb. Cov duab thiab qhov sib txawv ntawm cov fins tseem ceeb heev rau convection, ib yam nkaus. Nyias fins, ntim ze ua ke, muab koj thaj chaw ntau dua, tab sis yog tias koj mus hla, koj tsuas yog choke tawm ntawm cov cua. Ntau cov fins tuaj yeem ua rau rov qab.
Kev taw qhia kuj tseem ceeb, tshwj xeeb tshaj yog thaum koj tso siab rau lub ntuj convection -lub ntiajteb txawj nqus thiab txoj kev txav ntawm huab cua tuaj yeem hloov pauv lub dab dej kom zoo npaum li cas ntawm cov khoom pov tseg. Nrog cov kiv cua koom nrog, qhov twg koj muab tso rau lawv thiab yuav ua li cas huab cua ntws los ntawm kev teeb tsa tuaj yeem ua rau lossis tawg ua haujlwm. Thiab tsis txhob hnov qab cov ntaub ntawv thermal interface; lawv txuas qhov sib txawv ntawm qhov chaw tshav kub thiab lub dab dej, txo qis ntawm kev sib cuag.
Tag nrho cov ntsiab lus me me no tuaj ua ke los txiav txim siab seb koj lub dab dej ua kom sov ua haujlwm zoo npaum li cas. Nws tsis yog hais txog ib yam nkaus xwb -nws yog cov lej ntawm txhua qhov chaw.

Kev xaiv cov khoom siv thiab kev tsim khoom
Xaiv cov khoom tsim nyog yog qhov tseem ceeb thaum koj tab tom tsim lub dab dej kom sov. Feem ntau, tib neeg xaiv aluminium lossis tooj liab vim tias ob qho tib si ua haujlwm zoo rau kev hloov cua sov. Aluminium sawv tawm vim nws lub teeb, pheej yig, thiab zoo nkauj yooj yim rau cov duab- yog li nws yog qhov nyiam ua ntau qhov chaw ib zaug. Copper tuaj yeem ua kom sov tau zoo dua, tab sis nws hnyav dua thiab pheej yig dua. Nyob rau hauv qhov chaw nruj, nws yog ib qho uas pom tooj liab rau lub hauv paus (qhov twg nws tseem ceeb tshaj plaws), thiab tom qab ntawd aluminium fins kom tag nrho qhov hnyav.
Txoj kev tsim khoom tiag tiag zoo li koj tuaj yeem ua nrog lub dab dej kub. Rau kev tsim qauv ncaj nraim, extrusion tau txais txoj haujlwm tiav. Xav tau ntau cov fins nyias ntim ze ua ke? Skiving ua haujlwm xav tsis thoob, shaving cov fins txoj cai los ntawm ib daim hlau. Yog tias koj xav sib xyaw cov ntaub ntawv lossis txhawb kev ua haujlwm, kev sib koom ua ke fin technology muab kev xaiv rau koj. Tuag casting cia koj ua cov duab nyuaj, thaum CNC machining ntsia hlau cov ntsiab lus rau kev txiav txim. Thiab kev tsim khoom ntxiv-uas yog 3D luam ntawv, qhov tseem ceeb- coj txhua yam ntawm cov tsiaj qus, cov qauv zoo nkauj uas koj nyuam qhuav ua tsis tau ua ntej.
Txhua yam ntawm cov txheej txheem no los nrog nws tus kheej txheej ntawm pros thiab cons. Qee qhov pheej yig dua, lwm tus muab kev hloov pauv kom zoo rau koj, thiab qee qhov ntsuas tau zoo dua rau kev ua haujlwm loj. Kev xaiv qhov yog tiag tiag nyob ntawm seb koj qhov project xav tau dab tsi tshaj plaws.
Thermal Performance Optimization Techniques
Yog tias koj xav kom tau txais txiaj ntsig zoo tshaj plaws ntawm lub tshuab hluav taws xob compact, koj yuav tsum tau sib xyaw cov qauv tsim tweaks nrog cov khoom kuaj. Cov kws ua haujlwm feem ntau vam khom cov kua dej sib txawv, lossis CFD, los qhia seb huab cua txav li cas thiab qhov kub li cas. Qhov no cia lawv pom cov teeb meem me ntsis thiab kho cov duab ntawm cov fins. Ntau qhov chaw saum npoo ntawm cov fins pab tshem tawm cov cua sov sai dua, tab sis yog tias koj ntim lawv nruj dhau, cov cua ntws poob thiab kev ua haujlwm raug mob. Yog li, nws yog txhua yam hais txog kev tawm tsam txoj cai sib npaug.
Qee zaum kev kho deg, zoo li anodizing, tuaj rau hauv kev ua si. Cov no tsis tsuas yog pab nrog thermal tawg tab sis kuj tiv thaiv corrosion. Txhawm rau kom cov cua kub kis mus rau qhov chaw, cov neeg ntxiv cov kav dej kub lossis cov pa vapor chambers -tshwj xeeb tshaj yog rau cov khoom siv uas kub thiab xav tau ntau tshaj qhov kev teeb tsa yooj yim. Airflow tseem ceeb heev. Muab cov kiv cua thiab cov qhov cua tso rau hauv qhov chaw ntse ua kom cov cua sov tawm hauv lub cev. Thiab tsis txhob las mees cov interfaces. Kev siv cov khoom siv thermal zoo ntawm cov khoom siv txiav ua haujlwm thiab txhawb kev ua haujlwm. Thaum kawg, koj tsis tuaj yeem tsim thiab tsis nco qab. Kev sim, tweaking, thiab rov ua dua tshiab tau txais txiaj ntsig tiag tiag hauv kev tsim cov khoom siv hluav taws xob.
Daim ntawv thov thiab yav tom ntej Trends hauv Compact Heat Sink Design
Koj pom cov dab dej kub hauv txhua qhov chaw hnub no -hauv koj lub xov tooj, koj lub laptop, tsheb fais fab, txawm tias cov teeb ci LED hauv tsev. Lawv yog ib qho tseem ceeb rau kev ua kom cov cuab yeej ua haujlwm zoo yam tsis muaj qhov hnyav lossis hnyav. Siv cov tsheb fais fab, piv txwv. Yog tsis muaj cov dab dej kub zoo, cov roj teeb thiab hluav taws xob hluav taws xob yuav ua kom sov tsis dhau sijhawm. Nws yog tib yam deal nrog LED systems; Kev tswj xyuas kom sov zoo ua rau lawv ci ntsa iab rau xyoo.
Raws li thev naus laus zis hloov zuj zus mus, txhua tus tab tom nrhiav cov dab dej kub uas ua ntau dua thaum siv qhov chaw tsawg dua. Qhov ntawd txhais tau hais tias peb tab tom pib pom txhua yam khoom tshiab-zoo li graphene thiab cov khoom zoo nkauj zoo nkauj- uas rub tawm kom sov sai dua thiab hnyav ib yam dab tsi. Kuj tseem muaj ntau qhov buzz nyob ib ncig ntawm kev tsim khoom ntxiv. Nrog nws, koj tuaj yeem tsim cov dab dej kub hauv cov duab txawv txawv, uas ua haujlwm zoo dua li qub -fashioned blocky sawv daws yuav.
Thiab cia peb tsis txhob hnov qab ua kua txias. Nws tau dhau los ua - mus rau qhov kev xaiv rau siab - kev ua tau zoo iav uas ua kom sov. Saib tom ntej, qhov kev ua tiav tiag tiag yuav los ntawm kev sib xyaw cov khoom siv qib siab no, txiav- ntug kev tsim khoom, thiab cov tshuab hluav taws xob ntse uas tuaj yeem hloov kho sai. Ua siab ncaj, cov dab dej kub yuav me me, tab sis lawv yog ib qho loj heev rau kev ua kom tag nrho peb cov khoom siv thiab cov cav tov txias hauv qab.
