Muaj pes tsawg hom kev kho cua sov saum npoo?

Muaj ntau ntau txoj kev kho deg rau cov dab dej kub, nrog rau kev txau, anodizing, electrophoretic txheej, thiab electroplating thiab lwm yam. Ntawm lawv, electroplating txheej tuaj yeem txhim kho cov thermal conductivity ntawm lub dab dej kub, cov tshuaj tsuag txheej tuaj yeem ua rau lub ntsej muag roughness ntawm lub dab dej kub, anodizing. tuaj yeem txhim kho qhov corrosion kuj ntawm lub dab dej kub, thiab polishing tuaj yeem ua kom lub ntsej muag ci thiab zoo nkauj ntawm lub dab dej kub. Tam sim no cia peb kuaj xyuas tus yam ntxwv ntawm txhua qhov kev kho saum npoo.

 

Txau yog ib qho yooj yim thiab yooj yim txoj kev kho deg uas tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm lub dab dej kub, uas muaj qee yam kev tiv thaiv corrosion thiab kav ntev. Tsis tas li ntawd, muaj kev hloov pauv zoo hauv cov xim thiab cov txheej txheem xaiv.

 

Anodizing yog tus txheej txheem ntawm kev tsim cov yeeb yaj kiab dense oxide nyob rau saum npoo ntawm cov cua sov los txhim kho nws txoj kev tawm tsam rau oxidation thiab corrosion. Ntxiv mus, qhov saum npoo ntawm lub dab dej kub kho los ntawm anodizing feem ntau nthuav tawm cov xim zoo nkauj heev, thiab tuaj yeem txuas nrog cov xim.

 

 

Electrophoretic txheej yog ib txoj hauv kev tso cov txheej txheem ntawm cov khoom siv hluav taws xob rau saum npoo ntawm lub dab dej kub, uas muaj kev sib khi zoo thiab hnav tsis kam. Daim ntawv thov hluav taws xob kuj tseem pab kom muaj kev sib faib ntawm cov txheej txheem.

 

 

Electroplating yog ib txoj hauv kev tso ib txheej ntawm cov hlau rau saum npoo ntawm lub dab dej kub kom txhim kho nws cov tawv tawv thiab corrosion kuj. Feem ntau siv electroplated hlau muaj xws li tooj liab, nickel, thiab chromium.

 

Nyob rau hauv luv luv, txhua txoj kev kho saum npoo muaj nws cov yam ntxwv tshwj xeeb thiab kev siv, thiab xaiv cov txheej txheem kho saum npoo uas tsim nyog tuaj yeem muab kev tiv thaiv zoo rau kev ua haujlwm thiab kev zoo nkauj ntawm lub dab dej kub.

 

Kev kho deg feem ntau muaj kev cuam tshuam rau peb yam hauv qab no:
1. Hnav tsis kam: Qhov saum npoo ntawm cov khoom siv txhuas zoo tib yam (txawm nws yog lub casing lossis lub tshuab hluav taws xob) muaj cov xim " txhuas" xim (natural aluminium). Piv txwv li, tom qab txhuam koj txhais tes, feem ntau koj yuav pom cov cim dub ntawm koj txhais tes, uas yog ib qho microlayer ntawm txhuas thiab nws cov oxides. Aluminium yog ib yam hlau uas tsis tshua muaj hnav thaum tsis kho. Tom qab electrolytic oxidation (anodizing) nto kho, txhuas tsim ib txheej oxide uas yog thicker dua li uas ua nyob rau hauv tej yam kev mob. Lub deposited Al2O3 yog ib yam khoom nyuaj heev, yog li cov txheej no yog hnav heev resistant.

 

2. Tshuaj tiv thaiv: Aluminium alloys paub tias yuav tsum tau muab cais ua "corrosion resistant" cov ntaub ntawv nyob rau hauv qhov chaw huv si thiab qhuav. Txawm li cas los xij, txhuas nws tus kheej reacts yooj yim nrog ntau cov kua qaub thiab cov hauv paus, thiab txawm tias cov ntiv tes, yog tias tsis tshem tawm lub sijhawm, nws txaus los ua rau lawv oxidize tom qab ib ntus. Tab sis qhov saum npoo tom qab anodizing yuav tiv taus corrosion ntau dua, txawm tias nyob rau hauv cov xwm txheej hnyav, nws tuaj yeem tiv thaiv aluminium nto, uas yog vim li cas txhuas qhov chaw siv sab nraum zoov yog ib txwm anodized.

 

3. Kev ua kom txias txias: qhov kawg thiab qhov tseem ceeb tshaj plaws. Nto gloss Un kho tej yam ntuj tso txhuas muaj ib tug tsis tshua muaj emissivity (emissivity yog ib tug parameter ntawm lub peev xwm ntawm ib tug nto rau radiate tshav kub). Feem ntau cov ntaub ntawv muaj qhov emissivity ntawm li 0.95, thiab ntuj txhuas muaj anemissivity ntawm tsuas yog hais txog 0.05, uas txhais tau hais tias ib tug aluminium kub dab dej yuav ua tau zoo heev yog hais tias nws dissipated cua sov tsuas yog los ntawm hluav taws xob. Txawm li cas los xij, lub ntuj anodized heat sink nto muaj qhov emissivity ntau dua li lub ntuj txhuas, kwv yees li 0.80 siab dua. Tau kawg, convection kuj tseem yuav pab hloov cov cua sov, nyob ntawm seb qhov loj ntawm lub dab dej kub thiab qhov cua sov li cas lub dab dej kub.
