Kev sib piv ntawm tsib hom cua sov dab dej rau LED teeb Fixtures

Jul 29, 2024|

Qhov kev sib tw loj tshaj plaws tam sim no ntsib LED teeb pom kev zoo yog qhov teeb meem ntawm cov cua sov dissipation. Tsis zoo cua sov dissipation ua rau LED tsav tsheb fais fab mov thiab electrolytic capacitors ua bottlenecks nyob rau hauv lub ntxiv kev loj hlob ntawm LED teeb pom kev zoo fixtures, raws li zoo raws li qhov ua rau ntawm ntxov ntxov laus ntawm lub LED teeb qhov chaw.

 

Tam sim no, thaum lub teeb pom kev zoo ntawm LED yog siv, li ntawm 30% ntawm cov hluav taws xob hluav taws xob tau hloov mus rau lub teeb lub zog, thiab qhov seem yog hloov dua siab tshiab rau hauv thermal zog. Yog li ntawd, sai sai dissipating no loj npaum li cas ntawm tshav kub yog qhov tseem ceeb technical nam ntawm LED fixture structural tsim. Thermal zog yuav tsum tau dissipated los ntawm tshav kub conduction, tshav kub convection, thiab tshav kub tawg. Tsuas yog los ntawm cov cua sov sai sai tuaj yeem ua rau cov kab noj hniav kub hauv lub teeb pom kev zoo txo ​​qis, tiv thaiv lub zog hluav taws xob los ntawm kev ua haujlwm nyob rau hauv ib puag ncig kub kub, thiab tiv thaiv lub teeb ci LED los ntawm kev laus ntxov vim kev ua haujlwm kub ntev.

 

Cia peb ua raws li ZP HEAT SINK los tshawb txog cov cua sov txoj hauv kev ntawm LED teeb pom kev zoo:

Txij li cov teeb pom kev hauv LED tsis muaj infrared lossis ultraviolet rays, lawv tsis muaj hluav taws xob hluav taws xob tawg. Yog li ntawd, txoj kev tshav kub dissipation ntawm LED teeb pom kev zoo tsuas yog tso siab rau cov dab dej kub ua ke nrog LED teeb hlaws board kom dissipate tshav kub. Thaum tshav kub kub dab dej yuav tsum muaj lub luag hauj lwm ntawm cov cua kub conduction, cua sov convection, thiab tshav kub tawg.

 

Txhua lub dab dej kub, ntxiv rau kev ua kom kub sai sai los ntawm qhov chaw tshav kub mus rau saum npoo ntawm lub dab dej kub, feem ntau yog nyob ntawm convection thiab hluav taws xob kom dissipate cua sov rau hauv huab cua. Thaum tshav kub kub conduction tsuas yog hais txog txoj kev hloov mus, thaum tshav kub kub convection yog lub luag haujlwm tseem ceeb ntawm lub dab dej kub. Kev ua tau zoo ntawm cov cua sov dissipation yog tsuas yog txiav txim siab los ntawm qhov chaw tshav kub dissipation, cov duab, thiab lub peev xwm ntawm natural convection. Thaum tshav kub kub hluav taws xob tsuas yog ua lub luag haujlwm ntxiv.

 

Cov txheej txheem kub dissipation muaj xws li tuag-cam khwb cia txhuas cua sov dab dej, extruded aluminium heat sinks, stamped aluminium heat sinks, aluminium-yas composite heat sinks, thiab high thermal conductivity yas heat sinks.

 

Tuag-cam khwb cia aluminium kub dab dej
Tus nqi tsim khoom yog tswj tau, tab sis cov fins cua txias tsis tuaj yeem ua nyias, ua rau nws nyuaj rau qhov ua kom sov siab tshaj plaws. Cov ntaub ntawv txhuas tuag-casting rau LED teeb lub dab dej kub yog ADC10 thiab ADC12.

Stamped Aluminium Heat Sink
Siv cov punch xovxwm thiab pwm, steel lossis aluminium alloy daim hlau yog stamped thiab kos rau hauv lub khob zoo li lub dab dej kub. Sab hauv thiab sab nraud ntawm cov khoom siv hluav taws xob kub stamped yog du, tab sis qhov kub dissipation cheeb tsam yog txwv vim tsis muaj fins. Cov ntaub ntawv aluminium alloy feem ntau yog 5052, 6061, thiab 6063. Stamped qhov chaw yog lub teeb yuag thiab muaj kev siv cov khoom siv siab, ua qhov no yog cov nqi qis.

Lub thermal conductivity ntawm aluminium alloy cua sov dab dej yog qhov zoo tagnrho, ua rau lawv tsim nyog rau kev sib cais hloov cov khoom siv hluav taws xob tas li. Rau cov khoom siv hluav taws xob tsis raug rho tawm tam sim no, cov qauv tsim ntawm lub teeb yuav tsum xyuas kom muaj kev sib cais ntawm AC thiab DC, cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob kom dhau CE lossis UL daim ntawv pov thawj.

 

Aluminium-Plastic Composite Thaum tshav kub kub dab dej
Qhov no yog lub dab dej kub nrog lub plhaub yas thermal thiab ib qho txhuas core. Lub thermal yas thiab aluminium kub dab dej tub ntxhais yog molded nyob rau hauv ib kauj ruam ntawm ib tug txhaj tshuaj molding tshuab, nrog rau cov aluminium kub dab dej core pre-processed ua ib feem. Cov cua sov los ntawm LED teeb hlaws yog ua sai sai rau cov yas thermal los ntawm aluminium kub dab dej tub ntxhais. Lub thermal yas tsim cov cua convection nrog nws ntau tis kom dissipate tshav kub thiab radiates ib feem ntawm cov cua sov los ntawm nws nto.

 

Aluminum-Plastic Composite led Heat Sink

 

Thermal Plastic Density piv rau Die-Cast Aluminium thiab Ceramics
Qhov ntom ntawm cov yas thermal yog 40% tsawg dua li ntawm txhuas thiab ceramics tuag. Rau cov dab dej kub ntawm tib lub cev, qhov hnyav ntawm ib qho txhuas-yas sib xyaw ua kom sov tuaj yeem raug txo los ntawm ze li ib feem peb. Piv rau tag nrho-aluminium heat sinks, tus nqi ua haujlwm qis dua, lub voj voog ua haujlwm luv dua, thiab kev ua haujlwm kub qis dua. Cov khoom tiav tsis yooj yim tawg. Cov neeg siv khoom tuaj yeem siv lawv tus kheej txhaj tshuaj molding tshuab los tsim cov teeb pom kev zoo nrog cov qauv sib txawv. Aluminium-yas composite heat sinks muaj cov khoom zoo rwb thaiv tsev thiab yooj yim dhau cov qauv kev nyab xeeb.

 

High Thermal Conductivity Plastic LED Heat Sink1

 

High Thermal Conductivity Yas Thaum tshav kub kub dab dej
Lub siab thermal conductivity yas kub dab dej yog ib lub dab dej kub uas muaj cov thermal conductivity coefficient ntau dua li cov yas zoo tib yam, ncav cuag 2-9 W/m·K. Nws muaj cov thermal conduction zoo heev thiab muaj peev xwm tiv thaiv hluav taws xob. Nws yog ib yam tshiab ntawm insulating tshav kub dissipation khoom siv rau ntau lub hwj chim teeb, dav siv nyob rau hauv LED teeb xws li 1W txog 200W.

High thermal conductivity yas muaj qhov tiv taus qhov hluav taws xob txog li AC 6000V, haum rau kev siv nrog cov khoom siv hluav taws xob tsis raug rho tawm tam sim no thiab HVLED high-voltage linear cov khoom siv hluav taws xob tas li. Qhov no ua rau nws yooj yim rau cov teeb pom kev zoo li no kom dhau cov kev ntsuam xyuas kev nyab xeeb xws li CE, TUV, thiab UL. HVLED ua haujlwm nyob rau hauv high voltage (VF=35-280VDC)) thiab tsis tshua muaj tam sim no (IF=20-60mA), uas txo cov cua sov tsim los ntawm HVLED teeb hlaws board. High thermal conductivity yas kub dab dej tuaj yeem tsim los ntawm kev txhaj tshuaj molding thiab extrusion tshuab.

 

Nyob rau hauv lub siab thermal conductivity yas kub dab dej, nano-qhov loj me hlau ions yog densely faib ntawm PLA molecules, uas yuav txav tau ceev ceev ntawm kub kub, nce tshav kub hluav taws xob zog. Nws cov dej num yog superior rau cov khoom siv hlau ua cua sov. High thermal conductivity yas kub dab dej yog resistant rau kub kub, tsis tawg los yog deforming tom qab tsib teev ntawm 150 degree. Thaum siv nrog high-voltage linear tas li tam sim no IC tsav schemes, lawv tsis xav tau electrolytic capacitors thiab loj inductors, ho txhim kho lub neej ntawm tag nrho LED teeb. Cov phiaj xwm tsis muaj hluav taws xob cais tawm muaj kev ua haujlwm siab thiab tus nqi qis, ua rau lawv tshwj xeeb tshaj yog haum rau cov ntawv thov hauv cov raj fluorescent thiab cov hluav taws xob muaj zog thiab cov teeb pom kev zoo.

 

High thermal conductivity yas cua sov dab dej tuaj yeem tsim nrog ntau qhov txias txias fins. Cov fins cua txias tuaj yeem ua rau nyias nyias thiab ntau heev, nthuav dav cov cua sov hauv cheeb tsam. Cov fins txias cia li tsim cov cua convection kom dissipate tshav kub thaum ua hauj lwm, ua rau cov cua sov dissipation zoo. Lub tshav kub los ntawm LED teeb hlaws yog ncaj qha mus rau lub txias fins los ntawm lub siab thermal conductivity yas thiab sai sai dissipated los ntawm huab cua convection thiab nto hluav taws xob.

 

Qhov ntom ntawm cov thermal conductivity yas kub dab dej yog sib dua li txhuas. Qhov ceev ntawm txhuas yog 2700 kg / m³, thaum lub zog ntawm cov yas yog 1420 kg / m³, kwv yees li ib nrab ntawm txhuas. Yog li ntawd, rau cov dab dej kub ntawm tib lub cev, qhov hnyav ntawm cov yas cua sov yog tsuas yog ib nrab ntawm txhuas. Ntxiv mus, kev ua haujlwm yog yooj yim, nrog lub voj voog molding shortened los ntawm 20-50%, uas kuj txo tus nqi.

 

Cov saum toj no yog qhia los ntawm ZP HEAT SINK pab pawg neeg. Thov txuas ntxiv ua raws ZP HEAT SINK rau cov ntsiab lus txaus siab ntxiv.
