Txoj Cai Ua Haujlwm Ntawm Vapor Chamber
Vapor chamber feem ntau yog tiaj tus nyob rau hauv tsos, nrog ib tug kaw kab noj hniav nyob rau hauv thiab ua hauj lwm nruab nrab nyob rau hauv. Raws li kev siv sib txawv, tuaj yeem muaj cov qauv capillary lossis tsis muaj cov qauv capillary sab hauv. Nyob ntawm ib puag ncig uas siv lub vapor chamber, qhov nruab nrab ua haujlwm sab hauv yuav txawv.Lub phaj soaking diffuses tshav kub raws lub dav hlau ob sab, uas muaj peev xwm nthuav dav thiab kub dissipation zoo dua li lub tshav kub conduction raj uas diffuses tshav kub raws li. ib-dimensional kev taw qhia, tuaj yeem ua rau qhov kub thiab txias sib txawv, thiab tuaj yeem nqa lub zog thermal ntau dua.
Lub luag haujlwm tseem ceeb ntawm vapor chamber yog ua kom sov, kom cov cua sov diffuses sai thiab zoo li cov khoom sib xws, uas yog hu ua soaking phaj. Thaum cov cuab yeej hloov pauv cov cua kub ntau, qhov kub sib txawv kuj tseem me me, uas yog yuav luag isothermal, yog li nws yog hu ua qhov kub thiab txias sib npaug phaj.Lub vapor chamber diffuses cua sov raws li lub dav hlau ob sab, uas muaj kev nthuav dav zoo dua thiab cua sov. dissipation muaj peev xwm tshaj lub tshav kub conduction raj uas diffuses tshav kub raws li ib tug-dimensional kev taw qhia, yuav ua rau kom kub dissipation ntau yam, thiab muaj peev xwm nqa tau thermal zog ntau dua.
Hais txog cov ntaub ntawv, feem ntau siv vapor chamber yog: tooj liab vapor chamber, titaniumvapor chav, aluminiumvapor chav, stainless hlauvapor chav, lwm
Nyob rau hauv Structurally, nws yuav muab faib ua: capillary qauv thiab tsis muaj capillary qauv. Thevapor chamber nrog cov qauv capillary tuaj yeem muab faib ua sintered capillary vapor chamber, groovedvapor chav, woven meshvapor chav, fiber ntauvapor chavthiab lwm yam. Tsis yog capillary qauvvapor chavtuaj yeem muab faib ua lub ntiajteb txawj nqus pabvapor chav, oscillatingvapor chavthiab lwm yam.
Lub hauv paus ntsiab lus ua haujlwm ntawm vapor chamber nrog cov qauv sib txawv kuj txawv. Rau feem ntau sivvapor chavNrog capillary qauv, cov qauv capillary feem ntau yog teem rau sab hauv ntawm kab noj hniav. Cov kua ua hauj lwm puv rau hauv lub chamber yog kaw nyob rau hauv lub capillary qauv nyob rau hauv qhov kev txiav txim ntawm capillary quab yuam. Cov kab noj hniav uas tsis muaj cov kab noj hniav yog hu ua cov kab noj hniav. Thaum tshav kub kis los ntawm lub plhaub mus rau sab hauv capillary qauv ntawm evaporation cheeb tsam, cov kua ua hauj lwm nyob rau hauv lub capillary qauv pib vaporize tom qab tau rhuab nyob rau hauv ib tug tsawg nqus tsev vacuum, absorbs tshav kub zog thiab nthuav sai heev. Qhov nruab nrab ua haujlwm ntawm vapor theem sai sai ua rau tag nrho cov kab noj hniav. Thaum qhov nruab nrab ua hauj lwm ntawm vapor theem hu rau ib qho chaw txias, nws yuav rov condense rau hauv cov kua thiab tso cov cua sov absorbed thaum lub sij hawm evaporation. Cov kua ua haujlwm condensed yuav rov qab mus rau qhov chaw evaporation los ntawm cov yeeb nkab tsim los ntawm cov qauv capillary thiab nqus cua sov dua rau evaporation.
Vapor hamber nrog cov qauv sib txawv thiab cov txheej txheem muaj ntau yam kev siv:
1. Copper vapor chamber nrog thermal conductivity zoo dua feem ntau yog siv rau cov khoom siv hluav taws xob.
2.Qhov kev lag luam aviation feem ntau xaiv cov khoom sib dua aluminium lossis titanium vapor chamber vim qhov hnyav yuav tsum tau ua.
3.Xav txog tus nqi, lub zog siab IGBT feem ntau xaiv aluminium vapor chamber heatsink los yog aluminium heatsink nrog me me tooj liab chamber.
4.LED teeb pom kev zoo siv aluminium vapor chamber los yog kem soaking rau tus nqi txiav txim siab.
5.Rau cov ntawv thov kub qis, txhuas lossis stainless hlau vapor chamber feem ntau yog xaiv rau thermal conduction lossis lub zog.
6.Rau cov ntawv thov kub dua, tooj liab lossis stainless hlau vapor chamber feem ntau yog xaiv rau thermalconduction los yog zog.
