Hluav taws xob ntaus ntawv thermal tsim
Tam sim no, cov khoom siv hluav taws xob tau tsim los ntawm miniaturization, kev sib koom ua ke siab thiab kev ua haujlwm siab, uas txhim kho cov khoom siv hluav taws xob zoo, thiab qhov loj ntawm cov khoom siv hluav taws xob kuj tseem txhim kho mus rau miniaturization. Qhov no ua rau thermal tsim ntawm cov khoom siv hluav taws xob nyuaj dua. Cov khoom siv hluav taws xob yog tsim los ntawm ntau lub tsev modules. Thaum cov cuab yeej siv hluav taws xob, cov khoom siv hluav taws xob no yuav ua kom muaj cua sov ntau, Thiab qhov kub thiab txias hauv cov cuab yeej yuav nce sai heev. Yog tias cov cua sov tsis tuaj yeem kis tau thiab tawm hauv lub sijhawm, nws yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, thiab txawm tias nws puas tsuaj. Yog li ntawd, kev tsim cov cua kub dissipation yog ib qho tseem ceeb heev ntawm cov qauv tsim ntawm cov khoom siv hluav taws xob.
Txoj kev ntawm tshav kub hloov:
Feem ntau, muaj peb hom kev ua cua sov: conduction, convection thiab hluav taws xob.
Kev xaiv hom cua txias:
Vim tias cov khoom siv hluav taws xob muaj ntau yam khoom siv hluav taws xob, cov qauv ntawm cov khoom siv kuj yog qhov nyuaj. Muaj ntau hom kev hloov hluav taws xob sab hauv ntawm cov khoom siv hluav taws xob, thiab hauv ntau qhov xwm txheej, ntau qhov sib koom ua ke. Yog li ntawd, qhov tsis zoo ntawm cov khoom siv hluav taws xob thiab ib puag ncig ua haujlwm yuav tsum tau xaiv cov txheej txheem cua sov dissipation. Cov khoom siv hluav taws xob siv nyob rau hauv qhov chaw ntub dej yuav tsum tau txais kev tsim qauv kaw kom dissipate cua sov. Rau cov khoom siv hluav taws xob uas tsis xav tau kev tsim qauv kaw, lub tshuab hluav taws xob cua sov yog xaiv raws li cov txheej txheem cua sov dissipation, Txawm li cas los xij, rau cov khoom siv uas tsim kom muaj cua sov ntau, nws yog ib qho tsim nyog los txhawb cov cua kub dissipation los yog siv cua txias kom dissipate cua sov.
Feem ntau Thermal Design:
Ntuj convection cua txias: siv cov khoom siv plhaub ua lub tshuab hluav taws xob, kho cov cuab yeej cua sov ntawm lub plhaub, thiab ncaj qha hloov cov cua sov mus rau huab cua. Cov cua txias yog tsim nyog rau cov khoom siv hluav taws xob tsawg.
Forced convection cua txias: nws tsis yog tsuas yog yooj yim hauv kev tsim, tab sis kuj yooj yim thiab kev siv nyiaj txiag, thiab nws siv ntau dua vim nws muaj kev ntseeg siab.
Ua kua txias: vim nws cov kev ua haujlwm siab thiab kev cog lus, nws tau dav siv los ua kom txias hluav taws xob nrog cov thermal fluidity siab, thiab tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thermal tsim. Cov kua txias tuaj yeem yog ib-theem lossis ob-theem, feem ntau suav nrog kev ua kom txias ncaj qha lossis tsis ncaj qha.
TEC Txias: Nws qhov zoo yog tsis muaj suab nrov thiab kev vibration, compact qauv, yooj yim rau kev khiav lag luam thiab txij nkawm, tsis muaj tub yees, thiab lub peev xwm txias thiab txias ceev tuaj yeem hloov kho tam sim no. Nws yog dav siv nyob rau hauv cov tshuab nrog qhov kub thiab txias thiab lub zog ceev, thiab nws kuj tseem siv tau los ua kom txias qis-kub superconducting hluav taws xob.
Microchannel cua txias:
Ntawm anisotropic silicon wafers lossis substrates, anisotropic etching yog siv los tsim cov nplais. Thaum cov kua ntws los ntawm qhov chaw channel, cov kua tuaj yeem ua kom sov lossis ncaj qha nqus hluav taws xob. Lub sijhawm no, cov kua dej nyob hauv lub xeev tsis sib npaug, thiab lub zog hloov hluav taws xob yog qhov loj. Tsis tas li ntawd, kev sim qhia tau hais tias txawm tias thaum lub coolant ntws los ntawm microchannel nyob rau hauv ib theem, nws cov nyhuv txias yog zoo dua li ntawm kev siv cov kua boiling kom txias.
Nyob rau hauv xyoo tas los no, kev tshawb fawb txuas ntxiv hais txog kev tsim thev naus laus zis thev naus laus zis tau ua tiav. Thaum tsis tu ncua tsim ntau cov ntaub ntawv nrog cov thermal conductivity, kev siv dav ntawm cov ntaub ntawv no yuav ua kom zoo dua tam sim no cov cua sov dissipation technology ntawm cov khoom siv hluav taws xob.
