I-Electronic yabathengi

Isinki sobushushu sidlala indima ebalulekileyo ekulawuleni ubushushu obuveliswa zizixhobo zombane okanye zoomatshini, ukuqinisekisa ukuba zisebenza ngaphakathi kwemida yazo yobushushu ekhuselekileyo. Sisitshintshi sobushushu esingenakwenziwa esidlulisa ubushushu ukusuka kwisixhobo ukuya kwindawo yolwelo, efana nomoya okanye isisipholisi solwelo, apho sinokuchithwa ngokusebenzayo.

Kwimeko yeekhomputha, i-heat sinks isetyenziswa ngokuqhelekileyo ukupholisa iiyunithi ze-processor central (CPUs), iiyunithi ze-graphics processing (GPUs), ii-chipsets, kunye neemodyuli ze-RAM. Ezi zixhobo zivame ukuvelisa inani elibalulekileyo lobushushu ngexesha lokusebenza, kwaye ngaphandle kokupholisa okufanelekileyo, banokutshisa ngokukhawuleza, okukhokelela ekuthotyweni komsebenzi okanye ukungaphumeleli kwecandelo. Uyilo kunye nokwakhiwa kwendawo yokutshisa ukushisa kubaluleke kakhulu ekugqithiseni ubushushu ngokufanelekileyo. Uninzi lwezitsini zobushushu zisebenzisa ulwakhiwo oluphothiweyo olwenziwa ngemathiriyeli ye-thermal conductive njenge-aluminiyam okanye ubhedu. Amaphiko anyusa indawo yomphezulu wesitya sobushushu, evumela unxibelelwano olukhulu nolwelo olujikelezileyo kunye nokuphucula ukuhanjiswa kobushushu. Xa isixhobo sombane sisebenza, ubushushu buveliswa kwinqanaba lecandelo, njenge-CPU okanye i-GPU. Ukushisa kuqhutyelwa ngomzimba wesixhobo, kwaye ukukhusela ukufudumala, kufuneka kukhutshwe kwindawo engqongileyo. Apha kulapho i-heat sink ingena khona. I-heat sink ifakwe kwi-party eshushu, esebenza njengendlela yokushisa ukushisa ubushushu ukusuka kwinxalenye ukuya kwindawo yokushisa. Emva kokuba ubushushu budluliselwe kwi-heat sink, kufuneka buchithwe ngokufanelekileyo ukugcina ubushushu besixhobo kwimida ekhuselekileyo. Ukupholisa umoya yindlela eqhelekileyo, apho i-heat sink ibonakaliswe emoyeni ojikelezayo. Ummandla omkhulu we-heat-sink fins uvumela ukuchithwa kobushushu ngokufanelekileyo ngokusebenzisa i-convection. Umoya ojikelezileyo ufunxa ubushushu kwaye uyabuthwala, upholisa i-heat sink kunye necandelo eliqhotyoshelweyo. Kwizicelo ezifuna kakhulu okanye xa ujongene nobushushu obuphezulu kakhulu, ukupholisa ulwelo kungasetyenziswa. Isipholisi solwelo sijikeleza kwisinki yobushushu, sifunxa ubushushu, size ke sibuthwale busise kwiradiyetha apho bunokuchithwa khona. Ukupholisa ulwelo kunikezela nge-thermal conductivity ephezulu kunokupholisa komoya, okuvumela ukongezwa kokutshatyalaliswa kobushushu kunye namaqondo obushushu okusebenza anokuba ngaphantsi. Iintsini zobushushu aziphelelanga kwiikhompyuter; zikwasetyenziswa kakhulu kwizixhobo ze-semiconductor ezinamandla aphezulu ezifana ne-transistors yamandla, iilaser, kunye nee-LEDs. Ezi zixhobo zivelisa ukushisa okukhulu ngexesha lokusebenza, kwaye ngaphandle kokulawulwa kokushisa okusebenzayo, ukusebenza kwabo kunye nokuthembeka kungaphazamiseka. Iisinki zobushushu kwezi zicelo ngokuqhelekileyo ziyilwe ukuhlangabezana neemfuno ezithile zokushisa kwesixhobo.

Ukuqukumbela, ukucwiliswa kobushushu zizinto ezibalulekileyo kwiinkqubo zombane kunye nezomatshini, ezilawula ubushushu bezixhobo ngokugqithisela ngokufanelekileyo kunye nokuchitha ubushushu. Nokuba kwiikhompyuter, ii-transistors zamandla, okanye i-optoelectronics, iisinki zobushushu zidlala indima ebalulekileyo ekugcineni ukusebenza kwesixhobo, ukuthintela ubushushu obugqithisileyo, kunye nokuqinisekisa ubude obude kunye nokuthembeka kwamacandelo.
