HeatPipe Assembly heatsink rau lub zog siab LED teeb pom kev zoo
Lub zog hluav taws xob LED teeb pom kev zoo (siab dua 300W) feem ntau yog siv cov yeeb nkab cua sov cua sov rau cov cua sov dissipation, tab sis cov thev naus laus zis cua sov no tseem tab tom ntsib cov kev sib tw los ntawm PC processor heat dissipation.Muaj peb hom kev hloov tshav kub: conduction, convection thiab hluav taws xob. Txhua qhov kev tsim hluav taws kub dissipation yog ib daim ntawv thov ntawm cov qauv no.
Tam sim no, muaj peb txoj kev tshav kub dissipation nyob rau hauv LED kev lag luam: natural heat dissipation, yuam convection heat dissipation thiab kub yeeb nkab kub dissipation. Cov yeeb nkab cua sov dissipation yog qhov zoo tshaj plaws thiab ruaj khov thaum tshav kub kub dissipation ntaus ntawv tam sim no. Nws cov thermal conduction ceev yog kaum ob mus rau pua pua lub sij hawm siab dua li cov tsoos hlau. Qhov no feature yog zoo dua rau LED. Nws tuaj yeem hloov cov cua sov sai sai los ntawm kev coj mus rau lwm qhov chaw hauv txoj kev ceev tshaj plaws, uas yog sai dua thiab zoo dua li lwm txoj kev. Qhov tsis zoo yog tias tus nqi siab. Yog tias peb paub txog tus qauv ntawm cov yeeb nkab kub kub dissipation Tom qab modularization, nws cov nqi yuav tsis muaj teeb meem.
Los ntawm qhov kev xav ntawm kev siv, cov yeeb nkab cua sov muaj qhov zoo ntawm cov cua kub hloov ceev heev. Txhim kho nws hauv lub tshuab hluav taws xob tuaj yeem txo cov thermal tsis kam thiab ua kom cov cua sov ua kom zoo dua. Cov yeeb nkab cua sov, tseem hu ua" thermal superconductor", nws cov haujlwm tseem ceeb yog kev ua kom sov. Nws hloov cov cua sov los ntawm lub vapor-kua theem hloov ntawm kev ua haujlwm nruab nrab hauv lub tshuab nqus tsev kaw tag nrho. Nws muaj cov thermal conductivity siab, uas yog ntau pua lub sij hawm siab dua li cov tooj liab ntshiab.
Los ntawm ib qho kev pom, lub luag haujlwm tseem ceeb ntawm cov yeeb nkab cua sov yog los txhim kho qhov ua tau zoo ntawm kev hloov hluav taws xob thiab sai sai tshem tawm cov cua sov ntawm qhov chaw kub. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov yeeb nkab cua sov yog qhov yooj yim heev. Thaum tshav kub kub yeeb nkab yog muab faib ua evaporation cua sov kawg thiab condensation kawg. Thaum lub cua sov kawg yog rhuab, cov kua nyob ib ncig ntawm cov yeeb nkab phab ntsa vaporizes thiab generates chav. Lub sijhawm no, qhov no ntawm qhov siab nce, thiab cov chav ntws mus rau qhov kawg condensing. Tom qab mus txog qhov kawg ntawm condensing, nws yog txias thiab condensed rau hauv cov kua, thiab cua sov yog tso rau tib lub sij hawm. Thaum kawg, nws rov qab mus rau qhov kawg cua sov nrog kev pab ntawm capillary quab yuam kom ua tiav lub voj voog.

Cov txiaj ntsig ntawm LED heatpipe heatsink:
1.Me me. Ua tau raws li qhov xav tau ntawm miniaturization thiab kev koom ua ke ntawm LED tswj qhov system.
2. High TDP kev txhawb nqa rau LED nrog lub zog siab.
3. Kev ua haujlwm zoo thermal .Qhov thermal tsis kam ntawm cov khoom cua kub dissipation yog qhov me me, uas tuaj yeem tawm sai sai rau cov cua sov ntau hauv qhov chaw txwv, txhawm rau xyuas kom meej tias cov cuab yeej thiab cov khoom siv tuaj yeem ua haujlwm nyob rau hauv ib puag ncig kub tsis tshua muaj sijhawm ntev.
4. Tus nqi zoo txuag nrog lub sijhawm ua haujlwm ntev.
5. Tsis xav tau kev saib xyuas ntxiv.
6. Kev txuag hluav taws xob, tsis xav tau lub zog ntxiv los khiav lub cev.
7. Muaj kev ntseeg siab.
