Yeyiphi eyona nkqubo yokuvelisa isitingi sobushushu?

Kukho iinkqubo ezininzi zokuvelisa ezisetyenziselwaisinki yobushushuimveliso, kwaye eyona ilungileyo ixhomekeke kwiimfuno ezithile kunye neempawu ze-heat sink.Nangona kunjalo, ezinye iinkqubo zokwenza isinki sobushushu eziqhele ukusetyenziswa zibandakanya i-extrusion, i-forging ebandayo, ukutyibiliza, ukuphosa ukufa, kunye ne-CNC machining.Nantsi isishwankathelo senkqubo nganye:

1.Extrusion: Itekhnoloji ye-Aluminiyam yokukhulisa itekhnoloji ithetha nje ukufudumeza i-ingot ye-aluminium kubushushu obuphezulu obumalunga ne-520-540 ℃, ivumela ulwelo lwe-aluminium ukuba luqukuqelele kwi-mold ye-extrusion kunye ne-grooves phantsi koxinzelelo oluphezulu ukwenza i-sink yokuqala yobushushu, kwaye emva koko ukusika kunye nokugrumba okokuqala. isinki yobushushu ukwenza isinki yobushushu esetyenziswa ngokuqhelekileyo.Itekhnoloji ye-Aluminiyam ye-extrusion kulula ukuyiphumeza kwaye ineendleko zezixhobo ezisezantsi, eyenze ukuba isetyenziswe ngokubanzi kwimarike esezantsi kwiminyaka edlulileyo.Izinto ezisetyenziswa ngokuqhelekileyo ze-aluminium extrusion yi-Al 6063, ene-conductivity efanelekileyo ye-thermal kunye ne-processability.Nangona kunjalo, ngenxa yokulinganiselwa kwezinto zayo, umlinganiselo wobunzima ukuya kubude be-heat dissipation fins ayikwazi ukudlula i-1:18, okwenza kube nzima ukunyusa indawo yokutshatyalaliswa kobushushu kwindawo encinci.Ngoko ke, umphumo wokutshatyalaliswa kobushushu be-aluminiumi-extruded heat sinksuhlwempuzekile ngokwentelekiso,.Izinto eziluncedo: Utyalo-mali oluphantsi, umda ophantsi wobugcisa, umjikelo omfutshane wophuhliso, kunye nemveliso elula;Iindleko zokungunda eziphantsi, iindleko zemveliso, kunye nemveliso ephezulu;Inoluhlu olubanzi lwezicelo, kwaye ingasetyenziselwa ukwenza zombini iifins zokuchitha ubushushu kunye neenxalenye ze-fin ze-sink ezidibeneyo zokushisa.

2.Ukubumba okubandayo: Cold forging yinkqubo yokuvelisa apho i-aluminiyam okanyeisitya sobushushu sobheduyenziwa ngokusebenzisa amandla acinezelekileyo asekuhlaleni.Ii-arrays ezigqityiweyo zenziwe ngokunyanzela imathiriyeli ekrwada kwi-molding die by punch.Inkqubo iqinisekisa ukuba akukho amaqamza omoya, porosity okanye nabuphi na obunye ukungcola obuvaleleke ngaphakathi kwesixhobo kwaye ngaloo ndlela kuvelise iimveliso ezikumgangatho ophezulu kakhulu.Iinzuzo zezi: iindleko eziphantsi zokucwangcisa kunye nomthamo ophezulu wemveliso.Umjikelo wemveliso yokungunda udla ngokuba ziintsuku eziyi-10-15, kwaye ixabiso lokungunda liphantsi.Ifanelekile ukusetyenzwa kwee-cylindrical finsebandayo yokubumba i-sink yobushushu .Ukungalungi kukuba ngenxa yokulinganiselwa kwenkqubo yokubumba, akunakwenzeka ukuvelisa iimveliso ezinemilo enzima.

3.Ukutyibiliza: Inkqubo ekhethekileyo yokwenza isinyithi eyona nto ithembisayo kwisicelo esikhulu ekubunjweni okudibeneyoi-copper heat sinks.Indlela yokucubungula kukusika isiqwenga esipheleleyo seprofayili yentsimbi njengoko kufuneka.Ukusebenzisa isicwangcisi esikhethekileyo esilawulwa ngokuchaneka ukusika amashiti abhityileyo obungqingqwa obukhankanyiweyo, kwaye emva koko uwagobe anyukele kwimo ethe tye ukuze abe ziitsinki zobushushu.Izinto eziluncedo: Eyona nzuzo inkulu yetekhnoloji yokutyibiliza echanekileyo ilele kulwakhiwo oludityanisiweyo lokufunxa ubushushu ezantsi kunye namaphiko, kunye nendawo enkulu yoqhagamshelo (umlinganiselo woqhagamshelo), akukho nto i-interface impedance, kunye neefins ezityebileyo, ezinokuthi zisebenzise ngokufanelekileyo indawo yokushisa ubushushu. ;Ukongezelela, iteknoloji ye-skiving echanekileyo inokunqumla iindawo ezinkulu zokulahla ubushushu ngomthamo weyunithi (ukwandisa ngaphezu kwe-50%).Umphezulu wei-skived heat sinkukusikwa ngetekhnoloji yokutyibilika echanekileyo kuya kwenza amasuntswana arhabaxa, anokwenza indawo yokunxibelelana phakathi kwe-heat sink kunye nomoya ube mkhulu kwaye iphucule ukusebenza kakuhle kokutshabalalisa ubushushu.Ukungalungi: xa kuthelekiswa nokuqulunqwa kweenkqubo ezifanelekileyo kwimveliso emikhulu efana ne-aluminium extrusion, izixhobo ezichanekileyo zokutyibilika kunye neendleko zabasebenzi ziphezulu.Ii-Fins zinokuthi zigqwetheke kunye neendawo ezinzima.

4.Ukuphosa ukufa: Inkqubo esetyenziswa ngokubanzi yokusetyenzwa kweemveliso zealluminiyamu nganye.Inkqubo yokuvelisa ibandakanya ukunyibilikisa i-aluminium alloy ingot ibe yimeko yolwelo, ukuyizalisa kwi-die, usebenzisa umatshini wokuphosa ukuwenza ngexesha elinye, kwaye emva koko ukupholisa kunye nonyango olulandelayo ukuvelisa afa ukuphosa i-sink yobushushu.Inkqubo ye-die-casting idla ngokusetyenziselwa ukucubungula amacandelo anemilo enzima kakhulu.Nangona isenokubonakala igqithile ekusetyenzweni kwamaphiko okutshabalalisa ubushushu, iyakwazi ukuvelisa iimveliso ezinoyilo olukhethekileyo lolwakhiwo.I-alloy ye-aluminiyam eqhele ukusetyenziswa kwi-die-casting processing yi-ADC 12, eneempawu ezintle zokubunjwa kwe-die-casting kwaye ifanelekile ukuvelisa i-castings encinci okanye eyinkimbinkimbi.Nangona kunjalo, ngenxa yokungahambi kakuhle kwe-thermal, i-Al 1070 i-aluminium ngoku isetyenziswa ngokuqhelekileyo njengento yokuphosa e-China.Inomgangatho ophezulu we-thermal conductivity kunye nefuthe elihle lokutshatyalaliswa kobushushu, kodwa kukho iziphene malunga neempawu zokubumba i-die-casting xa kuthelekiswa ne-ADC 12. Izinto ezilungileyo: Ukuqulunqwa okudibeneyo, akukho impedance ye-interface;Amaphiko abhityileyo, ashinyeneyo, okanye antsonkothileyo anokwakheka, okwenza kube lula ukuphumeza uyilo olukhethekileyo.Ukungalungi: Iimpawu zomatshini kunye ne-thermal yezinto eziphathekayo azikwazi ukulinganisa.Iindleko zokubumba ziphezulu, kwaye umjikelezo wokuvelisa i-mold ubude, ngokuqhelekileyo kuthatha iintsuku ezingama-20-35.

 5.CNC Machining: Le nkqubo ibandakanya ukusika ibhloko eqinileyo yemathiriyeli usebenzisa umatshini olawulwa ngekhompuyutha ukwenza imilo ye-heat sink.Umatshini we-CNC ulungele ukuvelisa izixa ezincinci zeesinki zobushushu ezinoyilo oluntsonkothileyo, ezihlala zisetyenziselwa ukulungelelanisa amasinki obushushu amancinci.

Ekugqibeleni, eyona nkqubo yokuvelisa ingcono iya kuxhomekeka kwizinto ezifana nokusebenza okufunayo, ubunzima, umthamo, kunye neendleko.Xa uyilo lugqityiwe, kufuneka sihlalutye imeko ethile kwaye sikhethe eyona nkqubo ifanelekileyo yokuvelisa ukuhlangabezana neendleko kunye nokusebenza kwemveliso.
