Isici se-LED Cold Forged Heat Sink

Ukufosha nokucindezela ekamelweni lokushisa (eliphansi kunezinga lokushisa le-recrystallization lensimbi) kubangela ukunemba okuphezulu ekubunjweni komkhiqizo nosayizi, ukuminyana okuhle kwangaphakathi, amandla aphezulu, indawo ebushelelezi, nezinyathelo ezimbalwa zokucubungula, okwenza kube lula ukukhiqizwa okukhulu.

1. Good conductivity ezishisayo

Amasinki okushisa akhiwe ngamakhazaingakhishwa kusetshenziswa i-aluminium ehlanzekile engu-AL1070 ne-1050 ngesiqeshana esisodwa.I-thermal conductivity ye-aluminium ehlanzekile ye-AL1070 ingu-226W/mk, i-alloy aluminium (6063) ine-thermal conductivity engu-180W/mk, kuyilapho i-aluminium ye-die cast aluminium evamile (A380) ine-conductivity eshisayo engu-96W/mk kuphela. ngokushesha ukushisa okukhishwe ama-LED kungadluliswa, okwenza kube ngcono ukushabalaliswa kokushisa okuphelele kwezibani ze-LED.

2. Izinketho zezinto ezibonakalayo eziningi

Isikhunta sokubumba esibandayo singasebenzisa izinto zochungechunge lwe-AL1050, noma izinto zochungechunge lwe-AL6063 ukwenza ama-heatsink.Lezi zinto ezimbili zingabelana ngeqoqo lesikhunta ukwandisa ukukhetha kwamakhasimende futhi zihlangabezane nezidingo ezahlukene!

3. Isakhiwo esihle kakhulu sokukhipha ukushisa

Ipuleti lesisekelo (ipuleti eliphansi) le-heatsink eyakhiwe ebandayo lakhiwe ngokuhlangene namafins, futhi alikho igebe phakathi kwawo.Ukushisa okuvela ku-substrate kungadluliselwa kuma-fins okukhipha ukushisa ngaphandle kokuvinjelwa.Kodwa-ke amanye amasinki okushisa ahlanganisiwe noma aqinile, ama-substrate awo okukhipha ukushisa kanye nama-fins okukhipha ukushisa ayahlinzwa noma ahlanganiswe ndawonye ngemva komshini, kufanele abe nezikhala phakathi kwawo;Ukumelana ne-thermal okungaqondile kuyakhiqizwa.Ngesikhathi esifanayo, ukwanda okushisayo ngesikhathi sokusetshenziswa kwezibani kuzophinde kuholele esizukulwaneni nasekwandiseni izikhala, okuzokwandisa ukumelana nokushisa futhi akuhambisani nokushisa ukushisa.

4. Isakhiwo somkhiqizo esingavamile

Izingxenye ezingenhla nezingezansi zepuleti elingezansi zingakhiwa zibe izakhiwo ze-anisotropic ngokusebenzisaubuchwepheshe bokubumba obubandayo, futhi izinhlangothi zombili zingagxivizwa zibe yizimo ezikhethekile

5. Indawo enkulu yokukhipha ukushisa

Ugqinsi lwamaphiko okukhipha ukushisa osinki wokushisa obandayo lungafinyelela ku-0.7mm, futhi isikhala singafinyelela ku-1mm.Amaphiko amancane futhi amaningi okukhipha ukushisa akhulisa kakhulu indawo yokuxhumana nomoya, okuvumela kakhulu ukuguquguquka komoya kanye nokukhipha ukushisa.

6. Amaphiko ahlukahlukene

Inqubo yokubumba ebandayo ingahlangabezana nezimo ezihlukahlukene zamaphiko, njenge-cylindrical, ukwakheka kweshidi, ikholomu yesikwele, ikholomu ene-hexagonal, njll.

7. Isinki sokushisa esinosayizi omkhulu

Inqubo yokubumba ebandayo kanye nemishini yokucindezela komkhathi engaphezu kwamathani angu-3000 ingakhiwa ngesikhathi esisodwa ukuze ihlangabezane nosayizi abakhulu abangu-260 * 260 noma ngaphezulu,

8. I-aspect ratio ephezulu

Isici sesilinganiso samaheatsink akhiwe abandayo singaphezulu kwe-1:50, kuyilapho usinki wokushisa we-extrusion ngokuvamile uzungeze u-1:25.

9. I-multi directional inlet kanye ne-outlet air

I-air inlet kanye nesiqondiso sokuphuma kwe-heatsink ebandayo yokufaka izinhlangothi ezintathu.I-extrusion evamile iwukugeleza komoya okunezinhlangothi ezimbili kanye nokuphuma komoya ukuzivumelanisa kangcono nemvelo futhi kuzuzwe ukulahlwa kokushisa okungcono.

10. I-anisotropy yesakhiwo

I-cold forging heat sink yenziwa ngokubumba nokucindezela isikhunta, ngakho-ke ingacutshungulwa ekubunjweni ukuze kuqinisekiswe ukubukeka kwe-heterostructure ngemuva kwe-substrate, ukuze kuhlanganiswe kangcono nento yokushisa.

11. Usayizi omncane nesisindo esincane

Uma kuqhathaniswa ne-die-casting,ama-heatsinks e-extrusionkanye nezingxenye eziqinile, amasinki okushisa aqinile e-aluminium abandayo anezinzuzo ezingenhla.Amasinki okushisa evolumu afanayo nomumo angasetshenziselwa ukulahla ukushisa kwezibani zamandla aphezulu (njengamaheatsink endabuko angu-5W, kuyilapho amaheatsink e-aluminium ahlanzekile anevolumu efanayo nomumo angafinyelela ku-7W).Ngakho-ke, ukusebenzisa amasinki okushisa aqinile e-aluminium abandayo kuzonciphisa isisindo kanye nevolumu yezibani ze-LED, kunciphise izidingo zokubukeka njengamakholomu amalambu, futhi kuzuze ukuncipha kwezindleko zizonke, okwenza umkhiqizo uqhudelane kakhulu!

12. Ukubukeka okuhle

Izinto ze-heatsink ziyi-aluminium, futhi ubuso bungenziwa nge-anodized ukuze kuzuzwe ukubukeka okubushelelezi nokuhle.Imibala ehlukene (isiliva, emhlophe, emnyama, njll.) nayo ingafakwa nge-anodized ngokwezidingo zamakhasimende.Ingaphezulu le-aluminiyamu ye-die-casting ilukhuni futhi idinga ukwelashwa kokufafaza, okungahambisani nokuqeda ukushisa.

13. Ukusebenza okuphezulu

I-conductivity ephezulu, ukunemba okuphezulu kobukhulu nokuzinza, ukusebenza okuzinzile, nokuphathwa kalula kwendawo.Ngokwezilinganiso, ukusebenza kokushabalaliswa kokushisa kwe-aluminium ehlanzekile yokubumba okubandayo kuphakeme ngokuphindwe izikhathi ezi-2 kunohlobo olufanayo lwemikhiqizo yokusakazwa ngokufa, futhi isikhathi esingu-1 siphakeme kunesohlobo olufanayo lwemikhiqizo yephrofayili ye-aluminium.Njengamanje iyisixazululo esingcono kakhulu sokunqanyulwa kokushisa kwezinto zokukhanyisa ze-LED ezinamandla amakhulu.
