Bonded fin heat sinks yog ib txoj kev molding sib txawv piv rau cov txheej txheem molding ntawm extruded heatsink, stamped fins welded heatsink, thiab lwm yam heatsinks. Nws yog los ntxig cov fins ib qho los ntawm ib qho mus rau hauv lub substrate, yog li hloov cov cua sov rau cov fins.
Cov hauv qab no yog cov khoom raug cai ntawm kev sib txuas fins cua sov dab dej. Peb tuaj yeem pom tseeb tias hauv tooj liab lossis txhuas, muaj qhov sib npaug sib npaug, thiab cov cua sov dissipation fins tau muab tso rau hauv cov grooves ib qho los ntawm ib qho.
Dab tsi yog hom kev sib txuas fins cua sov dab dej? Lawv Qhov Zoo thiab qhov tsis zoo yog dab tsi?
Raws li txoj kev sib txuas ntawm cov fins thiab substrate, nws tuaj yeem muab faib ua hom hauv qab no:
1>Vuam hom: Cov fins thiab substrate yog txuas ua ke los ntawm cov vuam vuam, nrog rau qhov kub-kub brazing thiab qis-kub solder paste vuam;
Vuam muaj kev ua haujlwm zoo thaum tshav kub kub hloov pauv; Vuam aluminium substrate thiab lub dab dej kub nrog cov tshuaj txhuam hniav yuav tsum tau npib tsib xee plating ua ntej, uas yog kim thiab tsis haum rau cov dab dej kub loj loj;
Brazing tsis xav tau nickel plating, tab sis tus nqi vuam tseem siab.
2>Riveting hom: Tom qab cov fin tau muab tso rau hauv qhov yooj yim zawj, qhov zawj yog nias rau hauv nruab nrab los ntawm cov pwm, nruj nreem tuav cov fin kom ua tiav kev sib txuas ceev thiab ruaj khov.
Qhov kom zoo dua ntawm riveting yog qhov ua tau zoo ntawm kev hloov hluav taws xob, tab sis tom qab siv dua, muaj kev pheej hmoo ntawm qhov khoob thiab xoob ntawm cov khoom riveted;
Cov txheej txheem riveting tuaj yeem txhim kho kom muaj kev ntseeg tau, tab sis tus nqi kuj tseem yuav nce ntxiv. Yog li ntawd, riveted bonding fins radiators feem ntau yog siv rau hauv cov xwm txheej uas kev ntseeg siab tsis siab.
3>Adhesive type: Feem ntau, thermal conductive epoxy resin yog siv los ua kom nruj cov fins thiab substrate kom ua tiav cov cua sov.
Cov nplaum hom siv thermal conductive epoxy resin, uas muaj cov thermal conductivity qis dua piv rau vuam, tab sis tsim nyog rau cov dab dej kub nrog cov fins siab.
Kev tsim cov txheej txheem ntawm bonded fins radiator
Kauj Ruam 1: Ua aluminium / tooj liab substrate thiab fins raws li tus qauv tsim, thiab qhib lub substrate. Cov duab thiab haum haum ntawm qhov zawj yuav txawv nyob ntawm txoj kev sib txuas.
Kauj Ruam 2: Splice lub dab dej kub fins thiab substrate rau hauv ib qho tag nrho (vuam los yog kev sib txuas siv tau raws li kev tsim qauv)
Kauj Ruam 3: Tom qab kho lub substrate thiab lub dab dej kub, tom qab drilling, tapping, thiab milling ntawm ntau yam ntawm cov fins tuaj yeem ua tiav. Thaum kawg, kev kho deg sib xws tuaj yeem ua tiav los ua cov khoom tiav ntawm cov khoom sib txuas fin kub dab dej.
Daim ntawv thov ntawm Insert fins heat sink
Thawj qhov tshwm sim ntawm kev sib txuas cov dab dej kub yog los daws qhov teeb meem ntawm cov khoom sib txawv rau cov fins thiab substrates, nrog rau qhov nyuaj ntawm kev sib sau siab, ntom, thiab nyias cov cua sov hauv lwm txoj kev.
Tab sis nrog kev txhim kho thev naus laus zis, ntau lub tshuab hluav taws xob plug-in tau raug hloov los ntawm cov txheej txheem skiving fins.
Txawm hais tias nws yog ua ntej grooving, riveting, los yog vuam, cov txheej txheem ntawm kev sib raug zoo fin radiator yog qhov nyuaj thiab kim; Thiab cov skivied fins tuaj yeem ua tiav thinner, siab dua, thiab me me qhov sib nrug tshaj li kev sib txuas, thiab cov fins yog qhov tseem ceeb, nrog rau kev ua haujlwm kub zoo thiab kev ua haujlwm yooj yim. Nws kuj tuaj yeem daws teeb meem nrog cov ntaub ntawv sib txawv (xws li siv tooj liab aluminium composite daim hlau).
Raws li cov txheej txheem tsim rau cov dab dej kub, cov khoom siv hluav taws xob sib koom ua ke tseem muaj qhov txiaj ntsig tsis tuaj yeem hloov pauv hauv qee qhov xwm txheej lossis cov xwm txheej tsim tshwj xeeb. Piv txwv li, peb yuav tsum tau ntxig cov phaj nthuav dav rau hauv dej txias substrate, los yog ntxig lub ultra-thin vapor chamber rau hauv cov dej txias substrate, los yog ntxig cov yeeb nkab rau hauv cov tooj liab substrate. Qhov tseeb, peb txhua tus siv cov txheej txheem sib txuas fins.
xaus
Tsis muaj qhov sib txawv ntawm kev siv tshuab zoo thiab tsis zoo, thiab qhov tsim nyog tshaj plaws thiab tus nqi tsim nyog rau cov khoom lag luam yog cov thev naus laus zis zoo.
