Kodi njira yabwino kwambiri yopangira ma heat sink ndi iti?

Pali njira zingapo zopangira zomwe zimagwiritsidwa ntchitokoziziritsirakupanga, ndipo yabwino kwambiri imadalira zofunikira zenizeni ndi mawonekedwe a sinki ya kutentha.Komabe, njira zina zomwe zimagwiritsidwa ntchito popanga zowuma kutentha zimaphatikizapo extrusion, forging ozizira, skiving, kufa kuponyera, ndi CNC Machining.Nayi chidule cha njira iliyonse:

1.Extrusion: Aluminiyamu extrusion luso zimangotanthauza Kutenthetsa zitsulo zotayidwa ingot pa kutentha kwa pafupifupi 520-540 ℃, kulola zotayidwa madzi kuyenda mu nkhungu extrusion ndi grooves pansi kuthamanga kwambiri kulenga koyamba kutentha lakuya, ndiyeno kudula ndi grooving koyamba. choyimira chotenthetsera kuti apange choyimira chomwe chimagwiritsidwa ntchito kwambiri.Ukadaulo wa aluminium extrusion ndiosavuta kugwiritsa ntchito ndipo uli ndi zida zotsika mtengo, zomwe zapangitsanso kuti zigwiritsidwe ntchito kwambiri pamsika wazaka zam'mbuyomu.Zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu extrusion zakuthupi ndi Al 6063, zomwe zimakhala ndi matenthedwe abwino komanso osinthika.Komabe, chifukwa cha kuchepa kwa zinthu zake zomwe, chiŵerengero cha makulidwe ndi kutalika kwa zipsepse zowononga kutentha sikungathe kupitirira 1:18, zomwe zimapangitsa kuti zikhale zovuta kuonjezera malo opangira kutentha m'malo ochepa.Choncho, kutentha kutaya zotsatira za aluminiyumuextruded kutentha kumamirandi osauka,.Ubwino: Ndalama zochepa, luso lochepa laukadaulo, kadulidwe kakang'ono kachitukuko, komanso kupanga kosavuta;Mtengo wotsika wa nkhungu, mtengo wopangira, ndi kutulutsa kwakukulu;Lili ndi ntchito zosiyanasiyana, ndipo lingagwiritsidwe ntchito popanga zipsepse zamtundu uliwonse wa kutentha ndi zipsepse zazitsulo zophatikizira kutentha.

2.Kuzizira kozizira: Cold forging ndi njira yopangira momwe aluminiyamu kapenamkuwa kutentha lakuyaamapangidwa pogwiritsira ntchito mphamvu zoponderezedwa zokhazikika.Fin arrays amapangidwa ndi kukakamiza zopangira kukhala nkhonya.Njirayi imawonetsetsa kuti palibe thovu la mpweya, porosity kapena zonyansa zilizonse zomwe zimatsekeredwa mkati mwazinthuzo ndipo motero zimapanga zinthu zapamwamba kwambiri.Ubwino wake ndi: mtengo wotsika wopangira komanso mphamvu zambiri zopanga.Nthawi yopanga nkhungu nthawi zambiri imakhala masiku 10-15, ndipo mtengo wa nkhungu ndi wotsika mtengo.Oyenera pokonza zipsepse za cylindricalkuzizira koyambitsa kutentha kwakuya .Zoyipa zake ndikuti chifukwa cha kuchepa kwa njira yopangira, sizingatheke kupanga zinthu zokhala ndi mawonekedwe ovuta.

3.Kusambira: Njira yapadera yopangira zitsulo yomwe ndiyodalirika kwambiri pakugwiritsa ntchito kwakukulu pakuphatikizana kwamkuwa kutentha kumamira.The processing njira ndi kudula chidutswa chonse cha zitsulo mbiri ngati pakufunika.Pogwiritsa ntchito pulani yapadera yoyendetsedwa bwino bwino, kudula mapepala oonda a makulidwe odziwika bwino, ndiyeno nkuwapinda m'mwamba kuti akhale owongoka kuti akhale masinthidwe otentha.Ubwino: Ubwino waukulu waukadaulo wotsetsereka wotsetsereka wagona pakupanga kophatikizika kwa kutentha komwe kumayamwa pansi ndi zipsepse, zokhala ndi malo akulu olumikizirana (chiwerengero cholumikizira), chopanda mawonekedwe, ndi zipsepse zokulirapo, zomwe zimatha kugwiritsa ntchito bwino malo otenthetsera kutentha. ;Kuphatikiza apo, ukadaulo wothamanga kwambiri umatha kudula madera akuluakulu otaya kutentha pa voliyumu iliyonse (kuwonjezeka ndi 50%).Pamwamba paskived heat sinkodulidwa ndi mwatsatanetsatane skiving teknoloji imapanga tinthu tating'onoting'ono, tomwe tingapangitse kukhudzana pakati pa kutentha kwa kutentha ndi mpweya kukulirakulira ndikuwongolera kutentha kwachangu.Zoipa: poyerekeza ndi kupanga njira zoyenera kupanga zazikulu monga aluminiyamu extrusion, zipangizo zoyendetsa bwino komanso ndalama zogwirira ntchito ndizokwera.

4.Kufa kuponya: Njira yomwe imagwiritsidwa ntchito kwambiri pokonza zinthu zamtundu wa aluminiyamu.Kupanga kumaphatikizapo kusungunula aluminium alloy ingot kukhala madzi amadzimadzi, ndikudzaza mu kufa, pogwiritsa ntchito makina oponyera kufa kuti apange nthawi imodzi, kenako kuziziritsa ndi chithandizo chotsatira kuti apangekufa kuponya kutentha sink.Njira yopangira kufa nthawi zambiri imagwiritsidwa ntchito popanga zigawo zomwe zimakhala ndi mawonekedwe ovuta kwambiri.Ngakhale zitha kuwoneka ngati zochulukirapo pakukonza zipsepse zochotsa kutentha, zimatha kupanga zinthu zokhala ndi mapangidwe apadera.Aluminiyamu alloy omwe amagwiritsidwa ntchito kwambiri popangira kufa ndi ADC 12, yomwe ili ndi mawonekedwe abwino opangira ma kufa ndipo ndiyoyenera kupanga zoonda kapena zovuta.Komabe, chifukwa cha kusayenda bwino kwa matenthedwe, aluminiyamu ya Al 1070 tsopano imagwiritsidwa ntchito ngati zida zoponyera kufa ku China.Lili ndi matenthedwe apamwamba a kutentha komanso kutentha kwabwino, koma pali zofooka zina zokhudzana ndi kufa-kuponyedwa kupanga makhalidwe poyerekeza ndi ADC 12. Ubwino: Integrated kupanga, palibe mawonekedwe impedance;Zipsepse zopyapyala, zowundana, kapena zomangika bwino zimatha kupangidwa, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito mapangidwe apadera.Zoyipa: Zomwe zimapangidwira komanso kutentha kwazinthu sizingafanane.Mtengo wa nkhungu ndi wokwera, ndipo nthawi yopangira nkhungu ndi yayitali, nthawi zambiri imatenga masiku 20-35.

 5.CNC makina: Njirayi imaphatikizapo kudula chipika cholimba cha zinthu pogwiritsa ntchito makina oyendetsedwa ndi kompyuta kuti apange mawonekedwe a sinki ya kutentha.CNC Machining ndi oyenera kupanga timiyezi tating'ono ta kutentha tokhala ndi mapangidwe ovuta, omwe nthawi zambiri amagwiritsidwa ntchito posintha masinki ang'onoang'ono otentha.

Pamapeto pake, kupanga bwino kwambiri kumatengera zinthu monga momwe mukufunira, zovuta, kuchuluka, komanso mtengo.Kupanga kukamalizidwa, tiyenera kusanthula momwe zinthu zilili ndikusankha njira yoyenera kwambiri yopangira kuti ikwaniritse mtengo ndi magwiridwe antchito.
