Nrog rau kev loj hlob ntawm daim ntawv thov ntawm lub zog lasers, RF cov khoom siv, thiab cov khoom siv hluav taws xob ceev ceev hauv kev lag luam xws li kev tsim khoom, kev sib txuas lus, thiab kev kho mob,thermal tswjtau dhau los ua ib qho kev cuam tshuam tseem ceeb cuam tshuam rau kev ua haujlwm thiab kev ntseeg tau. Cov txheej txheem ua kom txias yog nce tsis txaus nyob rau hauv lub ntsej muag ntawm kev nce zog ceev. Nyob rau hauv xyoo tas los no,micro-channel cua txiastau tshwm sim los ua ib qho kev ua kom txias txias, ua lub luag haujlwm tseem ceeb hauv kev kov yeej cov teeb meem no.
1. Micro-channel Cooling yog dab tsi?
Micro-channel cua txias yog hais txog kev siv tshuab ntawm kev tsim cov micron-scale channel cov qauv hauv cov txheej txheem txias-feem ntau yog ua los ntawm tooj liab lossis ceramic. Cov kua dej txias (xws li dej deionized lossis glycol-raws li kev daws teeb meem) ntws los ntawm cov channel no, ua kom muaj txiaj ntsig zoo ntawm cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob sib hloov. Cov channel no feem ntau yog nyob ntawm kaum mus rau ntau pua micrometers hauv qhov dav, yog li lub npe "micro-channel."
2. Qhov zoo ntawm Micro-channel cua txias
Piv nrog rau cov txheej txheem xws li cua txias los yog cov txheej txheem dej-txias daim hlau, micro-channel technology muaj ntau yam txiaj ntsig zoo:
①Tsis tshua muaj kub hloov efficiency:
Qhov loj ntawm thaj tsam ntawm thaj tsam-rau-ntim piv ntawm micro-channels ho txhim kho cov cua sov thiab convection, tso cai rau cov cua sov dissipation ntawm ntau pua watts ib square centimeter lossis ntau dua.
②Zoo heev kub uniformity:
Cov kua dej ntws hauv micro-channels ua kom muaj kev sib faib hluav taws xob, pab kom tsis txhob muaj qhov chaw kub.
③Compact qauv:
Micro-channel coolers tuaj yeem ua ke ncaj qha rau hauv cov khoom ntim, txuag chaw thiab txhawb kev tsim qauv tsim.
④Customizable tsim:
Channel cov duab, suav, thiab tus nqi ntws tuaj yeem raug kho kom haum rau cov khoom siv thermal.
3. Tej yam kev siv ntawm Micro-channel txias
Micro-channel cua txias qhia tau hais tias nws muaj txiaj ntsig zoo hauv ntau yam khoom siv hluav taws xob siab lossis kub kub flux:
①High-power laser arrays (xws li laser bars):
Pab tswj cov chip kub stability, txhim kho optical tso zis zog thiab beam zoo.
②Optical kev sib txuas lus modules (piv txwv li, EDFA amplifiers):
Xyuas kom meej thermal tswj thiab ncua lub neej ntawm cov cuab yeej.
③Lub zog hluav taws xob (xws li IGBT modules, RF amplifiers):
Tiv thaiv overheating nyob rau hauv siab loads, txhim khu kev ntseeg system.
④Kev kho mob thiab kev lag luam laser ua tshuab:
Xyuas kom thermal stability thiab machining raug thaum lub sijhawm ua haujlwm tas mus li.
4. Kev txiav txim siab tseem ceeb hauv Micro-channel Cooler Design
Kev vam meej micro-channel cua txias system yuav tsum xav txog kev tsim qauv:
①Channel geometry:
Cov kev xaiv xws li ncaj, serpentine, lossis staggered channel yuav tsum phim cov khoom siv hluav taws xob faib hluav taws xob.
②Kev xaiv khoom:
Cov khoom siv thermal conductivity siab (xws li tooj liab lossis ceramic composites) txhawb kev hloov pauv sai thiab corrosion kuj.
③Cov dej dynamics optimization:
Flow tus nqi, siab poob, thiab hom coolant yuav tsum sib npaug thermal kev ua tau zoo nrog lub zog noj.
④Fabrication precision thiab sealing:
Micro-channel fabrication xav tau siab precision, thiab zoo sealing yog ib qho tseem ceeb los xyuas kom meej lub sij hawm ntev kev cia siab.
5. Cov ntsiab lus
Micro-channel cua txias tau dhau los ua ib qhomainstream tov rau high-power density electronic device thermal tswj, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas yuav tsum tau npaum, compact, thiab meej txias. Nrog kev nce qib tsis tu ncua hauv kev ntim khoom thiab kev tsim thev naus laus zis, cov kev daws teeb meem micro-channel yuav txuas ntxiv txhim kho, tsav cov cuab yeej ua haujlwm zoo dua thiab ntau lub tshuab compact.
