Hauv cov ntawv thov xws li lub zog lasers, cov khoom siv hluav taws xob hluav taws xob, thiab kev sib txuas lus, kev siv hluav taws xob ntau ntxiv thiab kev sib koom ua ke tau ua rau kev tswj xyuas thermal yog qhov tseem ceeb cuam tshuam rau cov khoom lag luam, kev ua neej, thiab kev ntseeg siab. Nrog rau micro-channel cua txias,macro-channel cua txiastau tshwm sim raws li cov tswv yim ua kua-txias kua. Nws cov qauv yooj yim dua, tus nqi qis dua, thiab kev saib xyuas yooj yim ua rau nws tsim nyog rau ntau yam xwm txheej.
1. Macro-Channel Cooling yog dab tsi?
Macro-channel cua txias suav nrog kev siv cov dej txias ntau dua (feem ntau nyob rau hauv millimeter ntau) ua rau hauv cov phiaj cua txias lossis cov qauv. Cov channel no qhia cov kua dej txias-feem ntau deionized dej, glycol-raws li kev daws teeb meem, lossis lwm yam kev lag luam coolants-los ntawm lub kaw lus kom tshem tawm cov cua sov thaum lub sijhawm ua haujlwm. Thaum ua ke nrog lub voj voog dej-txias, qhov kev teeb tsa no ua rau muaj kev tswj xyuas kom tsis tu ncua thiab ua haujlwm zoo.
2. Macro-Channel vs. Micro-Channel: Qhov txawv tseem ceeb
| Feature | Macro-Channel Txias | Micro-Channel Txias |
| Channel Loj | millimeter-scale (1mm mus rau ntau mm) | Micrometer-scale (teev mus rau pua pua μm) |
| Fabrication Complexity | Tsawg heev | Yuav tsum tau high-precision machining |
| Flow Resistance | Tsawg, kua ntws yooj yim | Siab, xav tau lub twj tso kua mis siab dua |
| Thaum tshav kub kub Exchange Efficiency | Nruab nrab, haum rau nruab nrab kub flux | High, zoo tagnrho rau huab cua kub flux |
| Nqi | qis | Siab dua |
| Daim ntawv thov | Nruab nrab-rau-tsawg tshav kub flux, siab ntseeg siab tshuab | High-power density, localized tshav kub qhov chaw |
3. Qhov zoo ntawm Macro-Channel Cooling
Txawm hais tias nws cov thermal efficiency qis dua micro-channel kev daws teeb meem, macro-channel cua txias muaj ntau yam txiaj ntsig zoo:
①Kev ntseeg siab:
Cov kab dav dav tsis tshua muaj kev cuam tshuam, muab kev ruaj ntseg ntev ntev-zoo tagnrho rau kev lag luam txuas ntxiv.
②Tsawg tus nqi tsim khoom:
Cov qauv yooj yim thiab ntau yam kev xaiv fabrication ua rau nws haum rau ntau lawm.
③Yooj yim ntawm kev saib xyuas:
Kev tu ncua sij hawm ntev, tus nqi tu qis, thiab tsawg dua cov kev xav tau ntawm kev ua kom huv huv.
④Muaj peev xwm ua kom txias txaus:
Rau cov khoom siv nrog cov cua kub nruab nrab, macro-channel txias ua haujlwm zoo tswj qhov kub thiab txias thiab ua kom ntev lub neej ntawm cov cuab yeej.
4. Daim ntawv thov Scenarios
Macro-channel cua txias yog dav siv hauv cov hauv qab no:
①Laser modules:
Tshwj xeeb tshaj yog rau nruab nrab-rau-lub zog qis lossis CW-hom lasers, macro-channel systems tuaj yeem yooj yim tuav cov thermal load.
②Lub zog hluav taws xob modules:
Xws li rectifiers, DC-DC converters, thiab IGBT modules.
③Fais fab amplifiers hauv kev sib txuas lus thiab radar systems:
Qhov zoo tshaj plaws rau cov cheeb tsam nyuaj uas xav tau kev ua haujlwm ntev, ruaj khov.
④Cov tshuab cua txias hauv cov khoom siv kho mob thiab kev lag luam:
Xws li semiconductor laser kho cov cuab yeej, laser npav tshuab, thiab lwm yam.
5. Kev txiav txim siab tsim tseem ceeb rau Macro-Channel Txias
Kev ua tiav macro-channel txias txias yuav tsum tau saib xyuas rau cov hauv qab no:
①Channel layout:
Yuav tsum tau ua kom zoo raws li cov cuab yeej siv hluav taws xob sib faib kom ua tiav qhov txias txias.
②Kev xaiv khoom:
Tooj, stainless hlau, lossis txhuas alloys feem ntau yog siv rau lawv cov thermal conductivity thiab corrosion kuj.
③Flow rate thiab twj tso kua mis compatibility:
Kev tsim kom zoo ntawm cov kua dej ceev thiab cov dej txias txaus kom muaj txiaj ntsig zoo ntawm kev sib pauv cua sov thiab qhov system stability.
④Standardized interfaces:
Ua kom yooj yim kev koom ua ke rau hauv cov neeg siv khoom lossis cov khoom siv.
6. Cov lus xaus
Macro-channel cua txias tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam siv vim nws qhov yooj yim, kev ntseeg tau, thiab kev saib xyuas yooj yim. Nws yog ib qho txiaj ntsig zoo thiab kev daws teeb meem, tshwj xeeb tshaj yog nyob rau hauv cov tshuab nrog nruab nrab mus rau qis thermal densities.
