Thermal Design ntawm Tub Rog Cov Khoom Siv Hluav Taws Xob
Nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, cov cuab yeej siv hluav taws xob tau koom nrog hauv kev ua haujlwm ntawm kev tiv thaiv lub teb chaws thiab cov cuab yeej ua tub rog tau dhau los ua qhov nyuaj, ntse thiab ntse.
Nyob rau tib lub sijhawm, vim cov kev xav tau ntawm kev siv tub rog rau cov khoom siv me me, lub teeb yuag, kev hloov kho thiab kev ntseeg siab, cov engineers tau ntsib nrog millimeter-wave electromagnetic compatibility thaum tsim cov txheej txheem, conduction txias nyob rau hauv high heat flux density, thiab sealing nyob rau hauv hnyav. ib puag ncig. Ib qho kev sib tw.
Thermal tsim teeb meem ntawm cov khoom siv tub rog
(1) Qhov chaw ua haujlwm ntawm cov cuab yeej siv tub rog yog qhov nyuaj Altitude, kub siab, tsis tshua muaj kub, av noo, kub poob siab, hnub ci thermal hluav taws xob, poob siab vibration, icing, thiab ntau yam hnyav ib puag ncig (fungus, suab puam, plua plav, soot, thiab lwm yam) tag nrho. muaj ntau theem ntawm kev cuam tshuam rau nws cov thermal tsim.
Ntxiv nrog rau txoj kev ciam teb nyuaj, qhov kev sib tw loj tshaj plaws hauv kev tswj xyuas thermal ntawm cov khoom siv hluav taws xob hauv kev lag luam tiv thaiv yog lub sij hawm luv luv thermal shock.
Cov khoom siv hluav taws xob no feem ntau raug rau ib puag ncig thermal heev.
Piv txwv li, lub dav hlau fighter nres nyob rau hauv lub hiav txwv Caribbean tam sim no yuav ua ib lub hom phiaj.
Lub dav hlau yog nyob rau hauv hiav txwv theem ntawm lub sij hawm no, thiab qhov kub thiab av noo yog heev haum.
Thaum lub dav hlau tawm mus, nws yuav nyob rau hauv qhov chaw siab tshaj, qis dua qhov kub thiab txias ib puag ncig, thiab ciam teb ntawm cov khoom siv hluav taws xob yuav hloov tsis pub dhau feeb lossis ob peb feeb. Yog li ntawd, cov khoom siv hluav taws xob hauv lub dav hlau yuav tsum muaj peev xwm ua haujlwm nyob rau hauv ntau qhov chaw ua haujlwm kub.
(2) Kev ua haujlwm loj thiab kub kub tsim
Vim yog lub luag haujlwm ntawm kev ua tub rog, cov khoom siv hluav taws xob no yuav ua rau muaj kev cuam tshuam loj ntawm cov ntaub ntawv, thiab tib lub sijhawm yuav tsum tau ua cov ntaub ntawv ceev ceev, sib xws, qis, thiab cov khoom siv hluav taws xob siv hluav taws xob yuav nce siab.
Yog li ntawd, qhov hnyav ib puag ncig thiab kev siv hluav taws xob sai sai ntawm cov nti ua rau kev tswj xyuas thermal ntawm cov khoom siv hluav taws xob hauv kev lag luam tiv thaiv ntsib cov teeb meem loj.
(3) Lub teeb yuag thiab zoo meej kev ntseeg tau nce qhov nyuaj ntawm thermal tsim Rau cov khoom siv hluav taws xob hauv huab cua lossis qhov chaw sab nrauv, qhov hnyav yog qhov tseem ceeb heev.
Qhov sib dua qhov hnyav, qhov ntev ntawm cov khoom yuav ua haujlwm ntxiv, thiab tus nqi qis dua. Obviously, vim yog cov yam ntxwv uas twb muaj lawm ntawm dav hlau fighters, missiles, tso tsheb hlau luam, thiab lwm yam, cov khoom hluav taws xob nyob rau hauv ib tug hnyav thermal ib puag ncig, yog li ntawd lub thermal kev cia siab ntawm cov khoom siv hluav taws xob nyob rau hauv kev tiv thaiv kev lag luam yog ib qho tseem ceeb heev.
Vim yog siv cov khoom siv hluav taws xob ua tub rog thiab qhov chaw ua haujlwm hnyav, lawv feem ntau nthuav tawm cov cua kub ntau dua. Zoo ib yam li lwm cov khoom siv hluav taws xob, lawv yuav tsum muaj qhov cua txias zoo, thiab qhov chaw loj, qhov hnyav, kev siv hluav taws xob, thiab kev siv hluav taws xob ntawm cov khoom siv yuav tsum raug txiav txim siab. Electromagnetic shielding thiab lwm yam kev xav tau.
Tam sim no, ntau tus engineers nyiam siv hybrid txias txoj kev rau thermal tsim ntawm cov khoom siv hluav taws xob.
Cov khoom siv hluav taws xob feem ntau siv cov cua txias cua txias, thiab cov khoom siv hluav taws xob cua txias yog siv rau cov khoom siv uas siv cua sov ntau.
Tab sis rau cov khoom siv hluav taws xob hauv qhov chaw dav hlau los yog qhov chaw sab nrauv, cov txheej txheem cua sov no tsis pom zoo, thiab yuav tsum tsim kom muaj cov kua dej txias ntau dua.
Piv txwv li, kev siv cov khoom siv thermal conductivity substrate, VC niaj hnub kub daim hlau, cov kav dej kub, TEC embedded nyob rau hauv nti Die, dav hlau txias los yog ncaj qha immersion kua txias, kom cov cua sov yuav kis tau mus rau cov kua, thiab ces mus rau cov kua. cooling system Nyob rau hauv lub tshav kub exchanger.
Tam sim no, cov khoom cua kub dissipation siv nyob rau hauv cov cuab yeej siv tub rog thiab cov cuab yeej siv hluav taws xob yog txhua yam tswj los ntawm lub taub hau kev lag luam.
Nws cia siab tias cov khoom siv hluav taws xob ntau dua nrog cov thermal conductivity ntau dua thiab kev ua haujlwm zoo dua yuav tshwm sim hauv lub tebchaws nyob rau ob peb xyoos tom ntej no, yog li lawv tuaj yeem tsis tsuas yog ua tau raws li cov cua kub dissipation ntawm tub rog cov khoom siv hluav taws xob, tab sis kuj muab kev lees paub thiab kev tiv thaiv. ib txwm ua haujlwm ntawm tub rog cov khoom siv hluav taws xob, thiab tuaj yeem txhawb nqa dav. Thiab siv los daws cov thermal tswj kev lag luam ntawm high-end pej xeem cov cuab yeej, thiab txhawb kev koom ua ke ntawm kev ua tub rog thiab pej xeem technology.
