Kev paub yooj yim ntawm cov txheej txheem heatsink anodized
Aluminium yog cov khoom siv thermal conductivity zoo, yog li nws feem ntau yog siv los tsim cov heatsinks. Aluminium heatsink feem ntau hu ua aluminium radiator. Tag nrho cov txhuas profiles ntawm no tsis yog tsuas yog rau txhuas, tab sis kuj rau txhuas alloy khoom. Aluminium muaj cov khoom muag muag thiab tsis zoo corrosion kuj, yog li qee qhov tsim nyog kev kho mob yuav tsum tau nqa tawm rau aluminium profile heatsink. Anodizing yog txoj kev kho saum npoo dav dav.
Anodizing feem ntau yog hais txog oxidation ntawm sulfuric acid, uas yog cov txheej txheem ntawm kev tsim cov oxide zaj duab xis ntawm txhuas cov khoom raws li cov khoom siv electrolyte thiab cov txheej txheem tshwj xeeb. Cov oxide zaj duab xis no txhim kho qhov tawv tawv thiab hnav tsis kam ntawm aluminium alloy, yog li nthuav dav daim ntawv thov ntau thiab ua kom lub neej ntev ntawm aluminium heatsink.
Cov txiaj ntsig ntawm extrusion Anodizing heatsink:
1. Lub siab thermal conductivity ntawm aluminium profile yog qhov kev txiav txim siab kom tswj tau cov cua sov kom zoo thiab qhov nruab nrab zoo tshaj plaws rau kev hloov hluav taws xob. Nws yog tus yam ntxwv los ntawm tsawg lub sij hawm, cua kub ceev, high efficiency, lightness, cleverness thiab ua tau yooj yim. Rau heatsinks ntawm tib qhov tshwj xeeb, qhov hnyav ntawm txhuas profile yog 1/3 ntawm cov hlau radiator.
2. Alumina tsim tom qab txhuas oxidation yog qhov zoo tshaj plaws tiv thaiv zaj duab xis, uas tuaj yeem zam nws cov oxidation ntxiv. Yog li ntawd, nws muaj cov tshiab thiab zoo nkauj tsos thiab muaj zog kho kom zoo nkauj.
3. Nyob rau hauv cov nqe lus ntawm heatsink ntau lawm txheej txheem, txhuas profiles yog qhov zoo tshaj plaws kev xaiv ntawm cov ntaub ntawv rau ua heatsinks. Nws muaj qhov zoo ntawm kev ua, nqi thiab qhov hnyav. Lub tshav kub dissipation ntawm cov yeeb nkab steel tsis zoo li ntawm txhuas, thiab txhuas muaj cov nqi tsim khoom qis dua tooj liab. Feem ntau, txhuas yog tsim nyog rau kev ua cua sov dab dej.
