Compostion thiab Daim Ntawv Thov ntawm LED Kub Sinks

LED luminaire cua sov dab dej yog ib qho hluav taws kub dissipation qauv tsim los ntawm lub hauv paus ntawm LED kub dab dej fins thiab ob peb fins. Tsis zoo li ib tus neeg fins, nws lub tshav kub dissipation unit muaj U-shaped los yog V-shaped channels tsim los ntawm khub ntawm cov fins uas nyob ib sab thiab lub hauv paus. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xav txog qhov cuam tshuam ntawm qhov sib nrug thiab tus naj npawb ntawm fin ribs ntawm kev ua haujlwm kub dissipation.

Raws li cov tswv yim lub zog ntawm cov nti txuas ntxiv mus ntxiv, cov kev xav tau siab dua tau muab tso rau ntawm lub tshuab ntim khoom ntawm cov hluav taws xob-hom LEDs.

 

Niaj hnub no, cov cua kub dissipation tau dhau los ua ib qho tseem ceeb txwv txoj kev loj hlob ntawm high-power LEDs. Tshwj xeeb tshaj yog rau cov ntawv thov nyob rau hauv automotive headlights, lub tshav kub dissipation ib puag ncig ntawm LED luminaires yog ntxiv aggravated vim lub structural designs uas yuav tsum tau ua raws li aesthetic txwv ntawm lub tsheb qauv. Yog li ntawd, kev txiav txim siab tshwj xeeb yog xav tau rau cov teeb meem kub dissipation ntawm LED luminaires.

 

 

 

Aluminium tshav kub fins yog ib qho kev siv hluav taws xob ua kom sov rau LED kub dissipation, siv txhuas cov cua sov fins ua ib feem ntawm lub casing los ua kom cov cua sov dissipation cheeb tsam.

1. Cov khoom siv hauv LED Kub Sinks
LED kub dab dej feem ntau yog tsim los ntawm cov khoom siv thermal conductivity, xws li txhuas thiab tooj liab. Aluminium yog qhov kev xaiv nrov vim nws lub teeb yuag thiab zoo thermal conductivity. Tooj liab, txawm tias hnyav dua, txawm tias muaj txiaj ntsig zoo hauv kev ua cua sov.

 

2. Kev txiav txim siab tsim
Kev tsim ntawm LED lub dab dej kub yog qhov tseem ceeb rau kev ua kom muaj cua sov zoo. Cov yam ntxwv xws li cov duab thiab qhov loj ntawm fins, kev teeb tsa ntawm cov fins, thiab cov qauv tag nrho ua lub luag haujlwm tseem ceeb. Optimizing cov qauv tsim kom ua kom txias txias thiab ua kom lub neej ntev ntawm LED.

 

3. Active vs. Passive Cooling
LED kub dab dej tuaj yeem ua haujlwm los ntawm passive lossis active txias txoj kev. Passive txias cia siab rau lub dab dej kub tsim thiab ntuj convection kom dissipate cua sov. Kev ua kom txias, ntawm qhov tod tes, koom nrog cov txheej txheem ntxiv xws li cov kiv cua lossis cov kua ua kua txias kom txhim kho cov cua sov, tshwj xeeb tshaj yog nyob rau hauv high-power LED daim ntaub ntawv.

 

4. Thermal Interface Materials (TIM)
Lub interface ntawm LED thiab lub dab dej kub yog qhov tseem ceeb. Cov khoom siv hluav taws xob sib txuas, xws li thermal paste lossis cov ntaub qhwv, feem ntau yog siv los txhim kho cov thermal conductivity ntawm LED thiab lub dab dej kub. Qhov no ua kom zoo dua cov cua sov hloov thiab kev ua haujlwm tag nrho.

 

5. Daim ntawv thov-Kev txiav txim siab tshwj xeeb
Cov ntawv thov sib txawv muaj cov kev xav tau sib txawv rau LED cov dab dej kub. Piv txwv li, nyob rau sab nraum zoov LED teeb pom kev zoo, lub dab dej kub yuav tsum tau tsim los tiv thaiv ib puag ncig yam xws li noo noo thiab kub hloov pauv. Kev nkag siab txog cov kev xav tau tshwj xeeb ntawm daim ntawv thov yog qhov tseem ceeb hauv kev tsim cov kev daws teeb meem kom zoo.

 

6. Kev nce qib hauv LED Cooling Technology
Kev tshawb fawb tsis tu ncua thiab kev txhim kho ua rau muaj kev nce qib hauv LED txias tshuab. Qhov no suav nrog cov qauv tsim hluav taws xob tshiab, cov khoom siv txhim kho, thiab cov txheej txheem ua kom txias dua. Kev hloov kho tshiab ntawm cov kev nce qib no yog qhov tseem ceeb rau cov tuam txhab tsim khoom thiab cov neeg tsim qauv los koom nrog cov thev naus laus zis tshiab rau hauv lawv cov khoom.

 

Nco ntsoov, qhov ua tau zoo ntawm LED lub dab dej kub tsis yog tsuas yog hais txog nws lub peev xwm los ua kom cua sov tab sis kuj hais txog qhov nws ua tau zoo npaum li cas nrog rau tag nrho cov qauv tsim thiab daim ntawv thov.
