Dab tsi yog high-density fins aluminium heat sink?
Dab tsi yog qhov high-density fins aluminium heat sink?
High-density fins aluminium heat sink muaj ntau qhov chaw tshav kub kub ntau dua li cov khoom siv hluav taws xob zoo ib yam. Lub high-density fins aluminium heat sink tsub kom lub tshav kub dissipation cheeb tsam thiab txo cov thermal kuj ntawm lub dab dej kub thiab cua kom ua tau zoo dua tshav kub dissipation. Qhov loj dua qhov chaw sib cuag nrog huab cua, qhov ceev ntawm cov cua kub dissipation, tab sis lub thickness txiav txim siab npaum li cas ntawm cov cua sov hloov.
Qhov zoo ntawm high-density fins aluminium kub dab dej
1) Qhov zoo ntawm thermal conductivity ntawm high-density fins aluminium kub dab dej: lub thermal conductivity ntawm txhuas kub dab dej yog 237w / mk, siab tsis kam, thiab high hlau tshav kub. Raws li kev ntsuam xyuas ntawm National Testing Center, nws cov hlau thermal lub zog yog 2.27W / Kg degree, thiab nws cov cua kub dissipation zoo dua li cov khoom siv hluav taws xob zoo tib yam.
2) Cov tsos thiab qauv zoo ntawm high-density fins aluminium kub dab dej: vim yog siv dav ntawm aluminium alloy kub dab dej profiles, muaj zog artistic cawv tau ntxiv rau hauv txoj kev loj hlob, thiab qib siab, elegant, zoo nkauj, fashionable thiab lwm yam. cov ntsiab lus tau raug txhaj rau hauv cov noob ntawm aluminium alloy cua sov dab dej, tseem niaj hnub no kev lag luam ntau zuj zus, thiab tau txais tos los ntawm ntau tus neeg uas nrhiav lub neej zoo.
3) Lwm qhov zoo ntawm high-density fins aluminium heat sink: aluminium profile heat sinks yog sib dua hauv qhov hnyav, yooj yim rau kev thauj thiab nruab, thiab yuav luag xoom qhov yuav tsum tau ua rau cov dej tsis zoo, thiab tsis tas yuav muaj kev tu dej tag nrho. Aluminium profile cua sov dab dej siv lub hauv paus ntsiab lus ntawm lub chimney kom dissipate cua sov, thiab cov cua qhia nyob rau hauv tsev, uas yog opposite rau phab ntsa. Nws tseem hu ua lub dab dej kub uas tsis haus luam yeeb ntawm phab ntsa.
4) Qhov zoo ntawm kev ua thiab kev tsim cov txheej txheem ntawm d high-density fins aluminium heat sink: cov txheej txheem ntawm aluminium profile heat sink profiles yog complex, thiab cov txheej txheem ntawm aluminium profile heat sink profile manufacturers suav nrog extrusion, laus, straightening, nto kev kho mob thiab lwm yam txheej txheem ntau lawm. Vim nws qhov zoo ntawm qhov yooj yim rau extrude, nws tuaj yeem raug extruded rau hauv ntau yam duab, yog li nws muaj qhov zoo nkauj zoo nkauj thiab muaj zog kho kom zoo nkauj. Tsis tas li ntawd, tom qab kev kho saum npoo, aluminium alloy profile cua sov dab dej yog coated nrog electrophoretic xim, thiab xim yog puag ncig thiab zoo nkauj.
Dab tsi yog graphite cua sov dab dej?
Graphite heat sink yog ib qho khoom siv ntawm LED txoj kev teeb thiab lub ntsiab ntawm LED tshav kub dissipation. Thaum LED txoj kev teeb yog teeb, nws yuav tsim kom muaj cua sov ntau. Yog hais tias nws tsis dissipate, nws yuav hlawv tawm lub Circuit Court board. Lub sijhawm no, graphite cua sov dab dej yuav los ua ke. Nrog txoj kev loj hlob sai ntawm LED thev naus laus zis, ntau cov khoom lag luam hauv kev lag luam zoo li yuav tsum tau ua me me, tshwj xeeb tshaj yog miniaturization ntawm high-power LED khoom.
Qhov zoo ntawm graphite cua sov dab dej
Graphite muaj thermal conductivity zoo heev, nrog rau thermal conductivity ntawm {{{0}}w/(mk) (sib npaug rau 2 mus rau 3 npaug ntawm tooj liab thiab 3 mus rau 5 npaug ntawm txhuas, thiab nws thermal conductivity deb tshaj. ntawm cov ntaub ntawv hlau xws li tooj liab thiab txhuas), thiab nws qhov hnyav kuj sib dua li ntawm tooj liab Aluminium yog lub teeb, nrog qhov ceev ntawm 0.85-1.9g / cm3 (qhov ntom yog sib npaug li 1/4 rau 1/10 ntawm tooj liab, thiab 1/1.3 rau 1/3 ntawm txhuas). Cov khoom ua tiav los ntawm ntuj graphite muaj cov thermal conductivity zoo dua li cov ntaub ntawv txhuas thiab tooj liab. Kev ruaj ntseg ntawm cov tshuaj lom neeg thiab lub cev muaj zog, cov khoom siv hluav taws xob zoo heev, yog cov khoom siv hluav taws xob uas muaj hluav taws xob zoo heev.
