LED Cold Forged Heat Sink Makhalidwe

Kupanga ndi kukanikiza kutentha kwa firiji (kutsika kuposa kutentha kwa zitsulo) kumapangitsa kuti zikhale zolondola kwambiri mu mawonekedwe a mankhwala ndi kukula kwake, kachulukidwe kabwino ka mkati, mphamvu yamphamvu, pamwamba yosalala, ndi masitepe ochepa okonzekera, kuti zikhale zosavuta kupanga zazikulu.

1. Good matenthedwe madutsidwe

Zozizira zopangira kutentha zimamiraakhoza extruded ntchito zotayidwa koyera AL1070 ndi 1050 mu chidutswa chimodzi.The matenthedwe madutsidwe wa koyera zotayidwa AL1070 ndi 226W/mk, aloyi zotayidwa (6063) ali madutsidwe matenthedwe matenthedwe 180W/mk, pamene wamba kufa cast aluminiyamu (A380) ali madutsidwe matenthedwe kokha 96W/mk Kuchulukira kwa matenthedwe madutsidwe, ndi mofulumira kutentha komwe kumatulutsidwa ndi ma LED kungathe kufalitsidwa, zomwe zimathandiza kwambiri kuti kutentha kwa nyali za LED kuwonongeke.

2. Zosankha zambiri zakuthupi

Kuzizira kopangira nkhungu kumatha kugwiritsa ntchito zida za AL1050, kapena zida za AL6063 zopangira ma heatsinks.Zida ziwirizi zimatha kugawana zisankho kuti ziwonjezere zosankha zamakasitomala ndikukwaniritsa zosowa zosiyanasiyana!

3. Mapangidwe abwino kwambiri opangira kutentha

Chimbale choyambira (mbale yapansi) ya heatsink yozizira yokhazikika imapangidwa ndi zipsepse, ndipo palibe kusiyana pakati pawo.Kutentha kochokera ku gawo lapansi kumatha kufalikira ku zipsepse zotulutsa kutentha popanda chopinga.Komabe ena omangika kapena brazed kutentha akumira, amene kutentha dissipate gawo lapansi ndi kutentha dissipation zipsepse ndi riveted kapena brazed palimodzi pambuyo Machining, ayenera kukhala mipata pakati pawo;Kukaniza kwa kutentha kosalunjika kumapangidwa.Panthawi imodzimodziyo, kuwonjezereka kwa kutentha panthawi yogwiritsira ntchito nyali kudzatsogoleranso ku mbadwo ndi kukulitsa mipata, zomwe zidzawonjezera kukana kwa kutentha ndipo sizikugwirizana ndi kutentha kwa kutentha.

4. Mapangidwe azinthu zachilendo

Kumtunda ndi kumunsi kwa mbale yapansi kumatha kupangidwa kukhala ma anisotropicteknoloji yozizira yopangira, ndipo mbali ziwirizo zikhozanso kusindikizidwa mu mawonekedwe apadera

5. Malo aakulu otaya kutentha

Kukhuthala kwa zipsepse zoziziritsa kutentha kwa sinki yoziziritsa kuzizira kumatha kufika 0.7mm, ndipo katayanidwe kake kamafikira 1mm.Zipsepse zopyapyala komanso zochulukirapo zowotcha zimachulukitsa kwambiri malo olumikizana ndi mpweya, zomwe zimapangitsa kuti mpweya uziyenda komanso kutulutsa kutentha.

6. Zipsepse zosiyanasiyana

The ozizira forging ndondomeko akhoza kukumana akalumikidzidwa zosiyanasiyana zipsepse, monga cylindrical, pepala zooneka, lalikulu ndime, hexagonal ndime, etc.

7. Kutentha kwakukulu kwakuya

Kuzizira kozizira komanso zida zamphamvu zam'mlengalenga zopitilira matani 3000 zitha kupangidwa munthawi imodzi kuti zikwaniritse kukula kwakukulu kwa 260 * 260 kapena kupitilira apo,

8. Chiŵerengero chapamwamba

Chiyerekezo cha ma heatsinks oziziritsa ozizira ndi pamwamba pa 1:50, pomwe kuzama kwa kutentha kwa extrusion nthawi zambiri kumakhala mozungulira 1:25.

9. Njira zambiri zolowera ndi kutulutsa mpweya

Malo olowera mpweya ndi njira yotulutsiramo thecold forging heatsink ndi yamitundu itatu.Extrusion wamba ndi mbali ziwiri zolowera ndi kutuluka kwa mpweya kuti zigwirizane ndi chilengedwe ndikukwaniritsa kutentha kwabwinoko.

10. Structural anisotropy

Kutentha kozizira kozizira kumapangidwa ndi kukakamiza ndi kukanikiza nkhungu, kotero kuti ikhoza kukonzedwa pa nkhungu kuti iwonetsetse maonekedwe a heterostructure kumbuyo kwa gawo lapansi, kuti agwirizane bwino ndi kutentha.

11. Kukula kochepa ndi kulemera kochepa

Poyerekeza ndi kufa-kuponya,ma heatsinks a extrusionndi mbali zolimba, zoziziritsa kukhosi za aluminiyamu zoziziritsa kuzizira zili ndi zabwino zomwe zili pamwambapa.Ma voliyumu omwewo ndi mawonekedwe otentha otentha amatha kugwiritsidwa ntchito pakuyatsa kutentha kwa nyali zamphamvu kwambiri (monga ma heatsinks achikhalidwe a 5W, pomwe ma heatsinks opangidwa ndi aluminiyamu omwe ali ndi voliyumu ndi mawonekedwe omwewo amatha kukwaniritsa 7W).Chifukwa chake, kugwiritsa ntchito zitsulo zoyera za aluminiyamu zoziziritsa kuzizira kudzachepetsa kulemera ndi kuchuluka kwa nyali za LED, kuchepetsa zofunikira pakuwoneka ngati mizati ya nyali, ndikukwaniritsa kutsika kwa mtengo wonse, kupangitsa kuti malondawo akhale opikisana!

12. Maonekedwe okongola

Zida za heatsink ndi aluminiyumu, ndipo pamwamba pake imatha kudzozedwa kuti iwoneke bwino komanso yokongola.Mitundu yosiyanasiyana (siliva, yoyera, yakuda, etc.) imathanso kusinthidwa malinga ndi zosowa za makasitomala.Pamwamba pa aluminiyumu yakufa ndi yovuta ndipo imafuna kupopera mankhwala, zomwe sizingathandize kuti kutentha kuwonongeke.

13. Kuchita bwino kwambiri

High conductivity, kulondola kwapamwamba kwambiri komanso kukhazikika, magwiridwe antchito okhazikika, komanso chithandizo chosavuta chapamtunda.Malingana ndi miyeso, kutentha kwa kutentha kwa aluminiyamu ozizira kuzizira ndi 2 kuwirikiza kawiri kuposa mtundu womwewo wa zinthu zoponyedwa ndi kufa, ndi nthawi imodzi kuposa zomwezo zamtundu wa aluminiyamu.Pakalipano ndi njira yabwino yothetsera kutentha kwa magetsi amphamvu kwambiri a LED.
