Taw qhia
Copper heat sinks yog ib qho tseem ceeb hauv kev tswj xyuas thermal niaj hnub no, tshwj xeeb tshaj yog thaum koj xav tau kev txav mus los sai. Nov yog nws ua haujlwm li cas: lub dab dej kub rub tawm cov cua sov ntawm cov khoom xws li cov khoom siv semiconductor thiab muab pov tseg rau hauv huab cua ib puag ncig nws. Nws ua tau zoo npaum li cas qhov no feem ntau yog los ntawm cov khoom siv thermal conductivity, ntom, thiab nws tau tsim li cas.
Tooj liab yeej ci ntawm no. Nws cov thermal conductivity hits ib ncig ntawm 385 mus rau 400 watts ib 'meter' -kelvin, uas tshuab aluminium tawm hauv dej. Uas cia tooj liab nplawm cua sov kom deb ntawm cov khoom me me sai dua, yog li koj tsis tshua muaj peev xwm khiav mus rau qhov kub dhau los yog qhov system tsoo.
Tias yog vim li cas koj thiaj li yuav pom tooj liab kub dab dej hauv hluav taws xob hluav taws xob, xov tooj cua iav, tsheb hluav taws xob, thiab siab - khoos phis tawj ua tau zoo - qhov tseem ceeb, nyob qhov twg koj tab tom cuam tshuam nrog cov cua sov. Tseeb, tooj liab hnyav dua thiab raug nqi ntau dua li txhuas, tab sis nyob rau hauv cov xwm txheej nyuaj, cov nyiaj them poob haujlwm yog tsim nyog.
Tau kawg, engineers tsis yog xaiv tooj liab xwb. Lawv saib qhov kev khiav hauj lwm kub, ntau npaum li cas lub hwj chim tau ntim rau hauv ib qho chaw me me, chav tsev ntau npaum li cas lawv tau txais, thiab cov peev nyiaj ua ntej yuav daws cov khoom zoo tshaj plaws.
Copper vs Aluminium: Qhov sib txawv tseem ceeb hauv Kev Ua Haujlwm Thermal
Yog tias koj tab tom sim xaiv ntawm tooj liab thiab txhuas cov cua sov, qhov loj tshaj plaws uas dhia tawm yog thermal conductivity. tooj liab yeej ntawm no- nws cov thermal conductivity yog li 60% siab dua txhuas, uas feem ntau ntog ntawm 200 thiab 235 watts ib meter -kelvin. Yog li, tooj liab kis cua sov sai dua, ob qho tib si hla lub hauv paus thiab mus rau hauv cov fins.
Tab sis aluminium los nrog nws tus kheej perks. Rau ib qho, nws yog txoj kev sib dua - txog ib feem peb qhov hnyav ntawm tooj liab. Qhov ntawd tseem ceeb heev yog tias koj yuav tsum khaws cov khoom txav tau yooj yim lossis tsis xav hnyav koj tus qauv tsim. Aluminium kuj yooj yim dua rau kev ua haujlwm nrog hauv khw. Cov neeg tsim khoom tuaj yeem extrude nws mus rau hauv txhua yam ntawm cov duab puab, thaum tooj liab yog qhov mob ntau dua. Ua hauj lwm nrog tooj liab feem ntau txhais tau tias cov kauj ruam ntxiv xws li machining, skiving, los yog kev sib txuas, uas tsuas yog ntxiv sij hawm thiab nqi ntau dua.
Corrosion kuj yog lwm yam uas yuav tsum tau xav txog. Aluminium ib txwm tsim cov txheej txheem oxide tiv thaiv, yog li nws tsis xeb yooj yim. Copper, ntawm qhov tod tes, qee zaum xav tau kev kho saum npoo, nyob ntawm seb koj siv nws.
Thaum kawg ntawm hnub, nws yeej los rau qhov koj lub cev xav tau tshaj plaws -kev ua haujlwm kub, lossis qee yam sib dua, pheej yig dua, thiab yooj yim dua los tsim. Txhua lub hlau muaj nws qhov chaw.

Thaum xaiv tooj liab hla Aluminium
Thaum koj nyob nraum tom qab qhov txias tshaj plaws nyob rau hauv ib qho chaw kaw ntom nti, tooj liab cua sov dab dej yog tawv kom yeej. Cov khoom siv zoo li siab -CPUs kawg, IGBTs, laser diodes, thiab cov inverters ceev tag nrho tso tawm ib tuj ntawm tshav kub hauv ib cheeb tsam me. Tooj liab yeej ci ntawm no- nws kis tau cua sov sai, ua kom sov, thiab hnov mob sai thaum tej yam kub. Nws yog qhov tshwj xeeb tshaj yog siv rau hauv cov tshuab uas koj tsis tuaj yeem suav rau ntau qhov cua, txij li tooj liab tau txais cua sov los ntawm lub hauv paus mus rau cov fins zoo dua li lwm cov ntaub ntawv.
Yog tias koj tab tom cuam tshuam nrog qhov kub thiab txias ambient los yog iav uas ua haujlwm nyuaj txhua lub sijhawm, tooj liab muab kev nyab xeeb rau koj. Ntxiv rau, hybrid cua sov dab dej- qhov twg lub hauv paus tooj liab raws li txhuas fins - tawm tsam qhov sib npaug zoo ntawm sab saum toj -notch conductivity thiab sib dua. Tseeb, tooj liab raug nqi ntau dua ua ntej. Tab sis nws them nyiaj los ntawm kev txiav cov kev ua tsis tiav thiab ua rau koj lub cev muaj kev ntseeg siab dua, uas tseem ceeb heev hauv kev teeb tsa tseem ceeb uas lub sijhawm poob qis tsis yog qhov kev xaiv.

Kev xav txog kev tsim thiab kev tsim khoom
Yog tias koj xav tau lub dab dej kub tooj liab uas ua tau nws txoj haujlwm, koj yuav tsum tau ua tib zoo mloog rau cov hauv paus -puab, thaj chaw saum npoo, thiab koj yuav txuas nws li cas. Muaj ob peb txoj hauv kev los ua cov khoom no, xws li CNC machining, skiving, stamping, lossis soldering fins txoj cai mus rau hauv paus. Skived tooj liab kub dab dej sawv tawm vim lawv carve nyias, nruj nreem ntim fins los ntawm ib qho thaiv ntawm tooj liab. Uas ua kom cov cua sov ntws zoo los ntawm lub hauv paus mus rau fin nrog tsis muaj kev tiv thaiv.
Tau kawg, tooj liab tsis yog lub teeb. Nws qhov ntom ntxiv hnyav hnyav, yog li koj yuav tsum tau noj cov khoom siv mounting xwb kom txhua yam ruaj khov. Tsis txhob hnov qab txog cov ntaub ntawv thermal interface, ib yam nkaus. Cov khaubncaws sab nraud povtseg me me ntawm qhov chaw tshav kub thiab lub hauv paus cua sov ua rau muaj qhov sib txawv loj -lawv txo qis kev tiv thaiv thiab txhawb kev ua haujlwm zoo.
Engineers yuav tsum xav txog ntau tshaj li cov hlau, ho. Airflow tseem ceeb. Koj yuav tsum tau saib seb huab cua txav mus los ntawm cov fins, qhov sib nrug deb npaum li cas ntawm cov fins, thiab txawm tias tag nrho cov txheej txheem kaw li cas yog tias koj xav tau qhov txias tshaj plaws. Thiab thaum nws los txog rau kev teeb tsa ua kua txias, tooj liab tseem mus - rau cov phaj txias. Nws tau txais sab saum toj -notch thermal conductivity thiab ua haujlwm zoo nrog txhua yam ntawm cov dej txias.
Tseeb, ntau tus neeg xaiv aluminium vim nws pheej yig dua thiab sib dua. Tab sis thaum koj tsis tuaj yeem them taus kev cuam tshuam ntawm kev ua tau zoo, tooj liab yog qhov tseem ceeb heev.
Kev ua tau zoo ntawm kev ua tau zoo thiab tus nqi ntev
Kev xaiv tooj liab tsis yog txhuas tsis yog kev xaiv cov khoom siv xwb- nws yog qhov ntse txav thaum koj mob siab txog kev ua tau zoo thiab ntev - lub sijhawm ua haujlwm. Copper heat sinks rub cov cua sov sai dua, ua kom kub tsis tu ncua, thiab cia li tuav tau zoo dua thaum cov khoom tawv. Koj yuav pom lawv muab tso ua haujlwm hauv tsheb fais fab, kev teeb tsa hluav taws xob tauj dua tshiab, cov tshuab ua lag luam, thiab cov khoos phis tawj ceev ceev- qhov chaw uas koj tsis tuaj yeem muaj feem cuam tshuam nrog cua sov.
Tseeb, tooj liab raug nqi ntau dua ua ntej. Tab sis nws them nyiaj los ntawm kev txo qis ntawm kev saib xyuas thiab pab koj cov cuab yeej siv tau ntev dua. Nws nres thermal qaug zog thiab ua kom qhov chaw tsis txhob poob rau lub sijhawm. Thiab yog tias koj tsim nws txoj cai thiab kho qhov chaw, tooj liab kub dab dej cia li mus, xyoo tom qab xyoo.
Raws li peb cov khoom siv me me thiab muaj zog dua, peb xav tau txoj hauv kev zoo dua los daws cov cua sov. Qhov ntawd yog qhov tooj liab tiag tiag ci. Nws nyob ntawm no kom nyob twj ywm raws li kev mus- rau cov khoom siv kom txias txias txhua txoj hauv kev.
