Kusamalira kutentha ndi chinthu chofunikira kwambiri pakutsimikizira kuti magwiridwe antchito ndi okhazikika komanso kuti zinthu zikhale ndi moyo wautali. Metallurgy imathandizira izi kudzera mu kusankha ndi kupanga heatsink, heat spreader, ndi heat pipe.
Aluminiyamu (Al) imagwiritsidwa ntchito kwambiri pa heatsink chifukwa ndi yopepuka, imatulutsidwa mosavuta m'zipsepse zoziziritsira, komanso yotsika mtengo. Mkuwa, wokhala ndi kutentha kwakukulu, nthawi zambiri umagwiritsidwa ntchito m'zigawo zomwe zimafuna kusamutsa kutentha mwachangu, monga maziko a heatsink kapena mapaipi otenthetsera. Mu mapangidwe ena, heatsink imaphatikiza aluminiyamu ndi mkuwa kuti ikwaniritse bwino magwiridwe antchito a kutentha ndi kulemera/mtengo. Njira yolumikizira zitsulo ziwiri zosiyana izi imafunikanso kuganizira za zitsulo, monga kupewa dzimbiri la galvanic ndikuwonetsetsa kuti kutentha kumalumikizana bwino.
Kuphatikiza apo, chotenthetsera kutentha pa purosesa chimagwiritsa ntchito zinthu zachitsulo zapamwamba komanso zosalala kuti zitsimikizire kuti phala lotentha likugwirizana bwino ndi phala lotentha. Ngakhale phala lotentha lokha nthawi zina limakhala ndi tinthu tachitsulo kapena ceramic kuti liwonjezere kutentha—ngakhale kuti izi zili mkati mwa zinthu zophatikizika, mfundo zachitsulo zimakhalabe zofunikira pakusankha tinthu ndi kukhazikika.
5. Kapangidwe ka makina: chivundikiro, chimango, ndi kukana dzimbiri
Zinthu zomangira nyumba monga ma PC cases, laputopu chassis, ndi ma enclosures amkati zimafuna zinthu zolimba koma zopepuka. Ma desktop cases ambiri amagwiritsa ntchito chitsulo chifukwa cha mphamvu zake komanso mtengo wake, pomwe zipangizo zonyamulika nthawi zambiri zimagwiritsa ntchito aluminiyamu kapena magnesium alloys kuti zikhale zopepuka. Metallurgy imathandiza kudziwa mtundu wa alloy ndi chithandizo chake (monga anodizing aluminiyamu) kuti ziwongolere kuwonongeka ndi kukana dzimbiri komanso kupereka mawonekedwe okongola.
Mu ma laputopu apamwamba kwambiri, ma aluminiyamu opangidwa mwaluso kwambiri amafuna zinthu zofanana komanso zokhazikika. Posankha aloyi, metallurgy imaganizira kuuma, kuthekera kwa makina, komanso kukana kusintha. Ngakhale zinthu zazing'ono monga zomangira ndi ma hinges ndi ntchito za metallurgy: kusankha chitsulo chosapanga dzimbiri kapena aloyi inayake kungapangitse kuti hinge ikhalebe yolimba pambuyo pa kutseguka ndi kutsekedwa kwa zikwi zambiri.
6. Kusunga deta: udindo wa chitsulo mu ma HDD ndi ma SSD
Mu ma hard disk drive (HDDs), metallurgy ndi yofunika kwambiri. Ma HDD plates amapangidwa ndi aluminiyamu kapena galasi yokutidwa ndi zinthu zamaginito zochokera ku alloy yachitsulo (monga cobalt). Mphamvu zamaginito za alloy—kuphatikizapo kukula kwa tirigu ndi momwe kristalo imayendera—zimakhudza kuchuluka kwa malo osungira. Mutu wowerenga-kulemba umagwiritsanso ntchito wosanjikiza woonda kwambiri wachitsulo pogwiritsa ntchito njira zodziwira bwino kwambiri.
Mu ma solid-state drives (SSDs), ngakhale deta imasungidwa pa ma semiconductor chips, chitsulo chimagwirabe ntchito pa njira zolumikizirana, ma connector pads, ndi zotchingira. Kuphatikiza apo, ma SSD ambiri amagwiritsa ntchito aluminiyamu heatsinks kuti asunge kutentha ndikuletsa kuwonongeka kwa magwiridwe antchito chifukwa cha kutentha.
7. Kuteteza maginito ndi kudalirika kwa chizindikiro
Zipangizo zamakompyuta ziyenera kutsatira miyezo ya electromagnetic interference (EMI). Chitsulo chimagwiritsidwa ntchito ngati chotchingira kuti chiteteze kuwala kwa chizindikiro kapena kusokoneza. Zitsanzo zikuphatikizapo zishango zachitsulo pazigawo zina za mamaboard, ma casing amagetsi (PSU), ndi chophimba choteteza pa zingwe. Metallurgy imathandiza kusankha zipangizo zomwe zimaletsa kusokoneza bwino pamene zimakhala zosavuta kupanga.
