Heatsinks ua lub luag haujlwm tseem ceeb hauv kev ua kom txias hluav taws xob thiab khoom siv tshuab. Lawv ua raws li passive heat exchangers, hloov cov cua sov los ntawm cov khoom kub mus rau cov kua nruab nrab.
Muaj ntau yam sib txawv ntawm cov dab dej kub. Qee qhov heatsinks yog tsim los ntawm tooj liab thiab qee qhov yog ua los ntawm txhuas. Tab sis, feem ntau, cov dab dej kub yog tsim los ntawm cov txheej txheem ntawm aluminium extrusion. Thiab cov extruded cua sov dab dej no kuj nquag anodized.
Cov txheej txheem Anodizing yog dab tsi?
Txoj kev zoo tshaj plaws ntawm kev ua tiav hauv cov tshuab hluav taws xob txias yog qhov saum npoo anodizing. Anodizing yog ib qho kev nyab xeeb ntawm cov txheej txheem electrochemical, uas tsis zoo li tha xim lossis hmoov txheej, tsis muaj ib yam dab tsi siv rau lub dab dej kub ntawm aluminium. Hloov chaw, anodizing thickens thiab toughens qhov tshwm sim tiv thaiv oxide txheej ntawm qhov chaw ntawm cov hlau. Anodizing tuaj yeem hloov qhov kev ntxhib los mos ntawm cov hlau, ua rau lub ntsej muag ruaj khov, corrosion thiab huab cua resistant.
Cov txheej txheem anodizing ua haujlwm li cas?
Koj cov aluminium extrusion heatsinks tau muab tso rau hauv lub da dej electrolytic.
Nyob rau hauv tus txheej txheem, lub extrusion kub dab dej hlau tsim cov anode (zoo electrode) ntawm ib tug electrolytic Circuit Court. Los ntawm cov kua qaub electrolytic, cov hluav taws xob tam sim no tso tawm hydrogen ntawm lub cathode (qhov tsis zoo electrode) thiab cov pa oxygen ntawm qhov chaw ntawm lub dab dej kub hlau anode (qhov zoo electrode), txhim kho qhov tso nyiaj ntawm hlau oxide. Cov kua qaub ua haujlwm yog sib npaug nrog tus nqi oxidation los ua ib txheej nrog qee qhov microscopic pores, {{0}} nm inch. Lub thickness ntawm lub dab dej kub hlau oxide nyob ntawm txoj kev anodizing thiab nyob nruab nrab ntawm 0.5 thiab 115 microns. Nws yog tswj los ntawm electrolyte concentration, acidity, kub, thiab cov txheej txheem hluav taws xob tam sim no thiab voltage.
Cov txiaj ntsig ntawm Anodized Heat Sink yog dab tsi?
1. Txhim kho Corrosion Resistance (Kev ntsuam xyuas acetic ntsev tsuag ntawm ISO 9227 cia siab tias anodized txhuas tsis pom pitting tom qab 24 teev)
2. Txhim kho hnav tsis kam (tshwj xeeb tshaj yog nyuaj anodizing)
3. Kev sib cais hluav taws xob ntau ntxiv (Kev tawg hluav taws xob sib txawv ntawm ob peb mus rau ob peb puas volts, nyob ntawm cov hlau thiab ntawm qhov xwm thiab tuab ntawm zaj duab xis)
4. Nce emissivity (siab dua hluav taws xob nyob rau hauv ntuj convection)
5. Kho kom zoo nkauj zoo nkauj / xim
Anodizing txhim kho corrosion kuj, hnav tsis kam, thiab hluav taws xob cais tawm, vim tias cov thickness ntawm cov oxide txheej.
Puas yog Anodizing Xim cuam tshuam rau kev ua haujlwm kub kub?
Anodized kub dab dej tuaj yeem dyed hauv cov xim xws li dub, xiav, ntsuab, thiab lwm yam. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov, txawm li cas los xij, tsuas yog qhov cuam tshuam tiag tiag ntawm cov xim yog qhov pom. Txawm li cas los xij ntawm cov xim, kev hloov pauv kub yuav tsis cuam tshuam. Qhov ntshiab anodized nto muaj tib yam emission yam ntxwv raws li dub anodized nto. Cov txiaj ntsig tseem ceeb ntawm cov dyes yog lawv qhov kev pom zoo.
Nws tseem yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias koj yuav tsum tsis txhob pleev xim los yog hmoov txheej thaum tshav kub kub dab dej. Cov coatings no yuav ua raws li cov insulator. Lawv yuav cuam tshuam tsis zoo rau kev hloov hluav taws xob.
