Heatpipe heatsinks manufacturing txheej txheem

Heatpipe heatsinksyog ib qho tseem ceeb ntawm ntau yam khoom siv hluav taws xob thiab cov tshuab kom dissipate cua sov zoo.Cov txheej txheem tsim khoom ntawm cov heatsinks no suav nrog ntau cov kauj ruam sib txawv thiab cov thev naus laus zis uas tso cai rau kev hloov hluav taws xob zoo.Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv cov ntsiab lus ntawm cov heatpipe heatsinks manufacturing txheej txheem, tshawb txog cov theem sib txawv thiab cov technologies siv.

Txhawm rau kom nkag siab txog cov txheej txheem tsim khoom ntawm cov kav dej heatsinks, nws yog ib qho tseem ceeb kom nkag siab ua ntej kom nkag siab tias lub rhaub dej yog dab tsi.Lub raj cua sov yog ib lub raj ntim tooj liab lossis txhuas uas muaj cov kua dej ua haujlwm me me, feem ntau yog dej, cawv, lossis ammonia.Nws tso siab rau cov hauv paus ntsiab lus ntawm kev hloov theem thiab kev ua haujlwm capillary kom hloov cov cua sov kom zoo los ntawm cov cua sov mus rau lub heatsink.

Thawj kauj ruam hauv kev tsim cov khoom siv heatpipe heatsinks yog kev tsim cov kav dej rau lawv tus kheej.Cov khoom siv feem ntau yog tooj liab vim nws cov thermal conductivity zoo heev.Muaj ob txoj hauv kev ua haujlwm rau kev tsim cov kav dej kub: txoj kev sib nqus thiab txoj kev sintering.

Nyob rau hauv txoj kev sib nqus, ntev, hollow tooj liab yeeb nkab tau ntim nrog cov dej ua haujlwm xaiv, tawm hauv qhov chaw me me ntawm qhov kawg rau cov vapor mus nyob.Tom qab qhov kawg ntawm cov kav dej kub yog muab kaw, thiab cov yeeb nkab raug tshem tawm kom tshem tawm cov huab cua lossis impurities.Lub heatpipe ces rhuab ntawm ib kawg kom induce cov kua rau vaporize, tsim siab nyob rau hauv lub raj.Qhov siab no ua rau lub vapor ntws mus rau qhov kawg txias, qhov twg nws condenses thiab rov qab mus rau qhov qub kawg los ntawm capillary nkaus, perpetuating lub voj voog.Cov kav dej kub yog tom qab ntawd kuaj cov dej xau thiab lub zog txhua yam ua ntej mus rau kauj ruam tom ntej.

Txoj kev sintering, ntawm qhov tod tes, suav nrog kev cog cov tooj liab lossis txhuas hmoov rau hauv qhov xav tau ntawm cov kav dej kub.Cov hmoov no yog ces rhuab kom txog thaum nws sinters ua ke, tsim ib tug khoom, ntxeem tau qauv.Tom ntej no, cov kua dej ua haujlwm tau ntxiv los ntawm kev txhaj tshuaj rau hauv cov qauv sintered lossis los ntawm kev muab cov kav dej tso rau hauv cov kua dej kom tso cai rau nws nkag mus rau cov khoom ntxeem tau.Thaum kawg, cov kav dej kub tau kaw, khiav tawm, thiab sim raws li tau hais hauv txoj kev nqus.

Thaum cov kav dej kub tau tsim, lawv txav mus rau theem tom ntej ntawm cov txheej txheem tsim khoom, uas cuam tshuam nrog kev txuas rau cov heatsinks.Lub heatsink, feem ntau yog ua los ntawm txhuas los yog tooj liab, yog lub luag hauj lwm rau dissipating lub tshav kub kis los ntawm lub heatpipes.Muaj ntau txoj hauv kev ua haujlwm los txuas cov kav dej rau lub heatsink, nrog rau kev sib txuas, kev sib txuas, thiab thermal nplaum sib txuas.

Soldering yog ib txoj hauv kev uas feem ntau siv los ntawm kev siv cov tshuaj txhuam hniav rau qhov sib cuag ntawm cov kav dej thiab cov heatsink.Cov kav dej kub yog muab tso rau hauv lub heatsink, thiab cov cua sov yog siv los yaj lub solder, tsim kom muaj kev sib raug zoo ntawm ob qho khoom.Brazing yog cov txheej txheem zoo sib xws rau kev sib tsoo tab sis siv qhov kub siab dua los yaj cov khoom muab tub lim uas tsim cov ntawv cog lus ntawm cov kav dej thiab cov cua sov.Thermal adhesive bonding, ntawm qhov tod tes, yog siv cov nplaum tshwj xeeb uas muaj cov thermal conductivity siab los txuas cov kav dej rau lub heatsink.Txoj kev no yog qhov tshwj xeeb tshaj yog thaum ua haujlwm nrog cov txheej txheem zoo li cov heatsinks.

Thaum cov kav dej tau ruaj ntseg txuas rau lub heatsink, lub rooj sib txoos tau kuaj xyuas kev ua haujlwm thermal thiab kev ua haujlwm zoo.Cov kev ntsuam xyuas no ua kom ntseeg tau tias cov kav dej thiab cov heatsink tau hloov pauv tau zoo thiab tuaj yeem tiv taus cov kev ua haujlwm uas lawv yuav raug.Yog tias muaj teeb meem lossis teeb meem raug kuaj pom thaum lub sijhawm kuaj, lub rooj sibtham raug xa rov qab rau kev rov ua haujlwm lossis muab pov tseg, nyob ntawm qhov hnyav ntawm qhov teeb meem.

Cov theem kawg ntawm kev tsim cov txheej txheem suav nrog kev ua tiav thiab kho saum npoo ntawm cov kav dej heatsinks.Cov kauj ruam no suav nrog cov txheej txheem zoo li polishing, anodizing, los yog txheej txheej heatsink lub ntsej muag txhawm rau txhim kho nws cov peev xwm ua kom sov, txhim kho corrosion, lossis ua tiav qhov zoo nkauj.Qhov kev xaiv ntawm kev ua tiav thiab kev kho saum npoo yog nyob ntawm qhov kev xav tau tshwj xeeb thiab kev nyiam ntawm daim ntawv thov lossis cov neeg siv khoom.

Hauv kev xaus, kev tsim cov txheej txheem ntawm cov kav dej heatsinks yog cov txheej txheem nyuaj thiab meej uas suav nrog ntau cov kauj ruam tseem ceeb thiab thev naus laus zis.Los ntawm kev tsim cov kav dej kom txuas lawv mus rau lub heatsink thiab ua tiav lub rooj sib txoos, txhua theem ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev hloov pauv tau zoo thiab ua haujlwm ntev ntawm lub heatsink.Raws li cov khoom siv hluav taws xob thiab cov tshuab txuas ntxiv mus txuas ntxiv thiab xav tau kev ua haujlwm siab dua thermal, cov txheej txheem tsim cov khoom siv hluav taws xob heatsinks yuav txuas ntxiv mus, tuav cov txheej txheem tshiab thiab cov ntaub ntawv kom tau raws li qhov xav tau ntawm kev lag luam.
