Dab tsi yog vapor chamber heatsink
Hais txog Vapor Chamber:
Vapor Chamber Heatsink yog tsim los ntawm cov phaj tooj liab kaw thiab ntim nrog cov kua me me xws li cov kua de-ionized uas tso cai rau cov cua sov kom sai sai ntawm qhov chaw. Sab hauv lub chamber nyob ib qho kev txhawb nqa sab hauv los tiv thaiv lub buckling ntawm chamber phab ntsa. Classified formalized li ibcov kav dej kub, lub vapor chamber yog ib qho ntawm qhov zoo tshaj plaws tshav kub kis kev xaiv ntawm lub hauv paus ntawm lub heatsink; thiab feem ntau yog siv rau cov khoom siv hluav taws xob siab. Thaum ua ke nrogstamped finsnws tsim cov cuab yeej siv hluav taws xob siab kawg uas tuaj yeem kis tau sai sai ntawm qhov chaw me me mus rau thaj chaw loj.
Vapor chamber heatsink ua haujlwm li cas:
Lub vapor chamber yog lub tshuab nqus tsev vacuum nrog cov qauv zoo ntawm cov phab ntsa sab hauv, uas feem ntau yog ua los ntawm tooj liab. Thaum tshav kub kis tau los ntawm qhov chaw tshav kub mus rau qhov chaw evaporation, lub coolant nyob rau hauv kab noj hniav pib vaporize tom qab tau rhuab nyob rau hauv ib puag ncig uas tsis muaj lub tshuab nqus tsev vacuum. Thaum lub sij hawm no, nws absorbs tshav kub zog thiab nthuav sai heev. Cov pa roj-theem cua txias nruab nrab sai ua rau tag nrho cov kab noj hniav. Thaum cov roj-theem ua haujlwm nruab nrab hu rau thaj chaw txias, condensation yuav tshwm sim. Thaum tshav kub kub evaporation yog tso tawm los ntawm condensation tshwm sim, thiab cov condensed coolant yuav rov qab mus rau lub evaporation tshav kub qhov chaw los ntawm microstructure capillary yeeb nkab. Qhov kev ua haujlwm no yuav rov ua dua hauv kab noj hniav.
Qhov zoo ntawm kev siv vapor chamber heatsink:
VC heatsink tuaj yeem txhim kho kev ua haujlwm thermal los ntawm 10- 30 feem pua ntawm cov tooj liab, thiab cov yeeb nkab cua sov raws li kev daws teeb meem. Hauv kev siv lub hom phiaj tseem ceeb, nws tsis tsuas yog txo qhov kub ntawm ntau degrees, tab sis kuj qee zaum tshem tawm qhov xav tau ntawm lub kiv cua saum lub heatsink, uas txhim kho qhov kev ntseeg siab ntawm lub cev thiab tshem tawm cov suab nrov.
Tsis tas li ntawd, tnws lub ntim me me tuaj yeem ua rau lub heatsink module tswj kom nyias raws li qhov nkag-theem qis zog noj; Thaum tshav kub kub conduction yog ceev, uas tsis tshua muaj feem yuav ua rau cov cua kub tsub kom. Cov duab tsis txwv, thiab tuaj yeem yog square, puag ncig, thiab lwm yam., uas yog tsim rau ntau yam cua sov dissipation ib puag ncig.
Kawg tab sis tsis kawg,lub vapor chamber yog ntau sib dua li cov khoom tooj liab, vim nws cov qauv sab hauv chamber. Feem ntau, lub vapor chamber raws li heatsink hnyav zoo ib yam li extruded aluminium heatsink, tab sis ua haujlwm zoo dua li tooj liab heatsink.
Yuav ua li cas kuaj yuav tsum tau mus rau loj ntau lawm:
Zoo li cov kav dej kub, vapor chambers yog cov khoom siv thermal txhim khu kev qha. Tsis muaj cov tshuab lossis tshuaj degradation nyob rau lub sijhawm Cov kev ntsuam xyuas hauv qab no tau ua niaj hnub ua kom paub meej tias cov kav ntev thiab rov ua dua.kev lav phib xaub ntawm vapor chambers:
Thermal Shock Test
Accelerated Life Test
Freeze Thaw Test
Kev ntsuam xyuas tawg
Cosmetic Degradation Test
Vim tias cov thev naus laus zis paub tab thiab tus nqi qis ntawm thermal module ntawm cov yeeb nkab cua sov, qhov tam sim no kev lag luam kev sib tw ntawm vapor chamber tseem qis dua ntawm cov yeeb nkab cua sov. Txawm li cas los xij, vim yog cov yam ntxwv ntawm cov cua kub sai sai ntawm lub vapor chamber nws daim ntawv thov yog tsom mus rau kev lag luam uas lub zog noj ntawm cov khoom siv hluav taws xob xws li CPU lossis GPU ntau dua 80W ~ 100W. Yog li ntawd, vapor chamber feem ntau yog cov khoom lag luam customized, uas yog tsim rau cov khoom siv hluav taws xob uas xav tau cov ntim me me lossis cov cua kub sai sai. Tam sim no, nws yog tsuas yog siv nyob rau hauv servers, high-end graphics phaib thiab lwm yam khoom. Nyob rau hauv lub neej yav tom ntej, nws kuj yuav siv tau nyob rau hauv lub tshav kub dissipation ntawm high-end telecommunications khoom thiab high-power LED teeb pom kev zoo.
