Cov qauv thiab kev siv ntawm Vapor Chamber
Copper mesh diffusion bonding thiab composite microstructure
Sib txawv ntawm cov yeeb nkab cua sov, cov khoom siv hluav taws xob zoo li qub yog thawj lub tshuab nqus tsev thiab tom qab ntawd txhaj cov dej ntshiab kom puv tag nrho cov microstructures. Qhov nruab nrab filling tsis siv methanol, cawv, acetone, thiab lwm yam, tab sis siv cov dej ntshiab degassed, yuav tsis muaj teeb meem tiv thaiv ib puag ncig, thiab kev ua tau zoo thiab ua haujlwm ntawm cov phaj kub zoo tuaj yeem txhim kho. Muaj ob lub ntsiab ntawm microstructures nyob rau hauv lub teeb kub phaj: hmoov sintering thiab multilayer tooj liab mesh, ob qho tib si muaj cov nyhuv tib yam. Txawm li cas los xij, cov hmoov zoo thiab sintering zoo ntawm cov hmoov sintered microstructure tsis yooj yim los tswj, thiab ntau txheej tooj liab mesh microstructure yog siv nrog diffusion bonding cov nplooj ntawv tooj liab thiab tooj liab meshes ntawm cov phaj kub, thiab nws qhov pore loj sib xws thiab tswj tau. zoo dua cov hmoov sintering Lub microstructure thiab zoo yog qhov ruaj khov. Lub siab sib xws tuaj yeem ua rau cov kua dej ntws zoo dua, uas tuaj yeem txo qhov tuab ntawm microstructure thiab txo cov thickness ntawm cov phaj ntub dej. Kev lag luam twb muaj phaj tuab ntawm 3.00mm nrog lub peev xwm hloov hluav taws xob ntawm 150W. Siv tooj liab hmoov sintered micro-structured soaking phaj, vim hais tias qhov zoo tsis yooj yim los tswj, tag nrho cov tshav kub dissipation module feem ntau yuav tsum tau supplemented los ntawm kev tsim cov kav dej kub.
Lub zog sib txuas ntawm diffusion-bonded multilayer tooj liab mesh yog tib yam li cov khoom siv hauv paus. Vim yog huab cua-tightness siab, tsis xav tau solder, thiab yuav tsis muaj microstructure blockage thaum lub sij hawm sib txuas cov txheej txheem. Zoo dua thiab durability. Tom qab siv txoj kev diffusion bonding, yog tias lub qhov ntws tawm, nws kuj tuaj yeem kho los ntawm kev ua haujlwm hnyav. Ntxiv nrog rau kev sib koom ua ke ntawm ntau cov txheej tooj liab mesh los ntawm diffusion, lub hierarchical tsim ntawm kev koom nrog tooj liab mesh nrog ib tug me me aperture nyob ze ntawm lub tshav kub qhov chaw kuj yuav ua rau lub evaporation cheeb tsam cov dej ntshiab replenish sai sai, thiab cov kev ncig ntawm tag nrho cov uniform kub phaj yog smoother. Cov neeg siab dua ua rau micro-structure modularization raws li cov qauv tsim hauv cheeb tsam, uas tuaj yeem siv rau cov cua sov dissipation tsim ntawm ntau qhov chaw tshav kub. Yog li ntawd, cov phaj kub sib txawv tsim los nrog kev sib txuas sib txuas thiab cov qauv hauv cheeb tsam hierarchical zoo heev ua rau cov cua sov hauv ib cheeb tsam, thiab cov nyhuv hloov hluav taws xob zoo dua li ntawm sintered microstructure uniform kub phaj.
Daim ntawv thov ntawm uniform kub board ntawm lub computer
Raws li cov cua sov yeeb nkab txias module tshuab yog qhov paub tab thiab tus nqi qis, kev lag luam tam sim no kev sib tw ntawm qhov kub thiab txias sib npaug phaj tseem qis dua rau cov yeeb nkab kub. Txawm li cas los xij, vim yog cov yam ntxwv ntawm cov cua kub ceev ceev ntawm cov phaj kub, nws daim ntawv thov tam sim no yog tsom rau kev lag luam uas lub zog siv hluav taws xob xws li CPU lossis GPU siab dua 80W-100W. Yog li ntawd, qhov kub thiab txias sib npaug phaj feem ntau yog cov khoom siv kho kom haum, uas yog tsim rau cov khoom siv hluav taws xob uas xav tau lub ntim me me los yog xav tau kom sai sai dissipate kub. Tam sim no, nws yog tsuas yog siv rau hauv cov khoom xws li servers thiab high-end graphics phaib. Nyob rau hauv lub neej yav tom ntej, nws kuj yuav siv tau nyob rau hauv high-end telecommunications khoom, high-power brightness LED teeb pom kev zoo, thiab lwm yam rau tshav kub dissipation.
Kev txhim kho yav tom ntej ntawm lub rooj tsav xwm kub tsis sib xws
Tam sim no, txoj hauv kev tseem ceeb rau kev tsim cov khoom siv hluav taws xob ntawm ob sab ntawm cov hluav taws kub dissipation capillary ntawm cov phaj kub tsis yog tsuas yog sintering, tooj liab mesh, tab sis kuj grooves thiab hlau nyias zaj duab xis. Nyob rau hauv cov nqe lus ntawm kev txhim kho thev naus laus zis, yuav ua li cas ntxiv txo cov thermal tsis kam ntawm cov phaj ntub dej thiab txhim kho nws cov kev ua kom sov kom haum rau cov fins sib zog xws li txhuas ib txwm yog lub hom phiaj ntawm R& D cov neeg ua haujlwm. Kev tsim cov khoom lag luam ntau ntxiv hauv kev tsim khoom thiab nrhiav kev txo tus nqi ntawm tag nrho cov cua sov dissipation daws yog tag nrho cov lus qhia ntawm kev lag luam' s txoj kev loj hlob. Nyob rau hauv cov nqe lus ntawm daim ntawv thov cov khoom, lub soaking phaj tau nthuav dav los ntawm ib-seem mus rau ob-dimensional tshav kub conduction piv rau cov cua sov yeeb nkab. Nyob rau hauv lub neej yav tom ntej, los daws tau lwm cov kev siv hluav taws xob dissipation, cov tshuaj so hauv phaj yog tsim los ntawm ib qho tom qab. Kev xyaum hais lus nyob rau theem tam sim no, yuav ua li cas nthuav dav daim ntawv thov kev lag luam rau cov khoom lag luam uas tau tsim los yog txoj haujlwm tseem ceeb tshaj plaws rau txhua qhov kev lag luam nruab nrab ntawm qhov ntsuas kub tam sim no.
Cia' s khob rau ntawm lub blackboard dua los sau cov ntsiab lus thiab daim ntawv thov scenarios ntawm 3D uniform kub board:
Cov phaj kub tsis sib xws yog ib hom ntawm cov yeeb nkab cua sov, uas tuaj yeem hloov pauv sai thiab nthuav tawm cov cua sov ntws los ntawm qhov chaw ntawm cov cua sov mus rau thaj tsam loj ntawm qhov chaw condensing, yog li txhawb kev tawg ntawm cov cua sov thiab txo cov cua kub ceev. nyob rau saum npoo ntawm cov khoom.
Cov qauv ntawm qhov sib npaug ntawm qhov kub thiab txias: cov kab noj hniav kaw tag nrho yog tsim los ntawm cov phaj hauv qab, cov ncej thiab cov phaj npog. Sab hauv phab ntsa ntawm kab noj hniav yog nruab nrog cov kua-absorbing capillary core qauv. Lub capillary core qauv tuaj yeem yog hlau hlau mesh, micro groove, thiab fiber ntau. Nws tuaj yeem yog cov hmoov hlau sintered core thiab ntau yam kev sib txuas ua ke. Yog tias tsim nyog, cov kab noj hniav yuav tsum tau nruab nrog cov qauv kev txhawb nqa kom kov yeej qhov deformation los ntawm kev nyuaj siab thiab kub nthuav dav vim lub tshuab nqus tsev tsis zoo.
Qhov zoo ntawm qhov kub thiab txias sib npaug phaj: qhov me me tuaj yeem ua rau lub tshuab hluav taws xob tswj kom nyias nyias raws li qhov nkag-theem qis zog noj; lub tshav kub conduction yog ceev ceev, thiab nws tsis tshua muaj feem yuav ua rau kub tsub zuj zuj. Cov duab tsis txwv, nws tuaj yeem yog square, puag ncig, thiab lwm yam., yoog mus rau ntau yam cua sov dissipation ib puag ncig. Tsawg pib kub; ceev hloov cua sov; zoo kub uniformity; siab tso zis zog; tus nqi tsim khoom tsawg; lub neej ua haujlwm ntev; lub teeb nyhav.
Daim ntawv thov ntawm lub rooj tsav xwm kub tsis sib xws hauv lub tshuab computer: Feem ntau cov khoom kub tsis sib xws yog cov khoom siv kho mob, uas tsim nyog rau cov khoom siv hluav taws xob uas xav tau cov ntim me me lossis xav tau kom sai sai rau cov cua sov. Tam sim no, nws yog tsuas yog siv nyob rau hauv servers, ntsiav tshuaj computers, high-end graphics phaib thiab lwm yam khoom. Nyob rau hauv lub neej yav tom ntej, nws kuj yuav siv tau nyob rau hauv high-end telecommunications khoom, high-power brightness LED teeb pom kev zoo, thiab lwm yam rau tshav kub dissipation.
