Ndi njira iti yopangira yomwe ili yabwino kwambiri pakuzama kwa kutentha kwa LED

Kufunika kwa sinki yotentha ya LED

Kutentha kwa LEDndi mbale yachitsulo yomwe imagwiritsidwa ntchito pochotsa kutentha, nthawi zambiri imayikidwa pansi pa nyali ya LED.Imatha kumwaza ndikutaya kutentha kopangidwa ndi LED, kusunga kutentha kwa LED mkati mwa malo otetezeka, ndikuwonetsetsa kuti nyali ya LED ikugwira ntchito bwino komanso moyo wautumiki.

Kuwala ndi moyo wautali wa nyali za LED zimadalira kwambiri kutentha kwa LED.Kutentha kwapamwamba kumatha kuchepetsa kuwala ndi moyo wautali wa nyali za LED, ndipo ngakhale kupangitsa kulephera kwawo.Chifukwa chake, kuzama kwa kutentha kwa LED ndikofunikira pakuchita komanso kudalirika kwa nyali za LED

Njira yayikulu yopangira sinki yotentha ya LED

Nazi njira zingapo zomwe zimagwiritsidwa ntchito popanga masinki otentha a LED:

1. Sinki yotentha yotuluka

Sinki yotenthetseraamapangidwa ndi kukankhira zitsulo zotentha za aluminiyamu kudzera muzitsulo zomwe zimafunidwa pamtanda, kenaka kudula kapena kuziwona mpaka kutalika komwe mukufuna kutentha.Njira ya extrusion iyi imalola kuti mapangidwe a zipsepse zovuta apangidwe.

2. Kuzizira kosungirako kutentha kwakuya

Chipinda chozizira chozizira kutenthaamapangidwa ndi njira yozizira yopangira, mapini apini amapangidwa pokakamiza aluminiyamu kapena zopangira zamkuwa kuti zipangike kufa ndi nkhonya pa kutentha kwanthawi zonse, mapini apitirire kuchokera pansi.

3. Kufa kuponyera kutentha sinki

Die casting ndi njira yopangira jakisoni wachitsulo chosungunula chamadzimadzi mopanikizika kwambiri mu nkhungu yolondola kwambiri.Nthawi zambiri amagwiritsidwa ntchito popanga misampha yamitundu itatu yokhala ndi mawonekedwe atsatanetsatane

Ndi njira iti yopangira yomwe ili yabwino kwambiri pakuyikira kutentha kwa LED?

Ngati LED kutentha kumira ndi maonekedwe ofanana, mitengo ya nkhungu zopangira kufa ndi yokwera, nkhungu zoziziritsa zoziziritsa kukhosi ndizochepa, ndipo mitengo ya nkhungu zotulutsa ndi yotsika.

Kuchokera pamalingaliro amitengo yopangira, mtengo wa extrusion profile Machining ndi wokwera, mtengo wa kufa-casting ndi wocheperapo, ndipo mtengo wopangira ndi kukanikiza ndi wotsika mtengo.

Kuchokera pakuwona ndalama zakuthupi, mtengo wazinthu ndi wotsika mtengo wa ADC12 kufa-casting, pomwe A6063 ndi yokwera mtengo kwambiri pakutulutsa ndi kupangira zida.

Tengani mawotchi otentha a LED nthawi zambiri amakhala ngati mpendadzuwa mwachitsanzo.

ngati extrusion ndondomeko, zinthu zambiri ntchito A6063, ubwino ndi kuti kutentha dissipation zotsatira za mankhwala ndi zabwino, ndi mankhwala pamwamba mankhwala yomalizidwa, monga anodizing, ndi zosavuta.Kuzungulira kwa nkhungu kumakhala kochepa nthawi zambiri masiku 10-15, ndipo mtengo wa nkhungu ndi wotsika mtengo.

Choyipa ndichakuti mtengo wa post Machining ndi wokwera ndipo zotulutsa zake ndizotsika.

Pogwiritsa ntchito kuponyera kufa kuti apange ma radiator a LED, zinthu za ADC12 zimagwiritsidwa ntchito ngati zinthu.

Ubwino wake ndi: kutsika mtengo wopangira, kutulutsa kwakukulu, komanso kuthekera kopanga ma radiator amitundu yosiyanasiyana ngati nkhungu ilola.

Zoipa: Mtengo wa nkhungu ndi wokwera, ndipo nthawi yopangira nkhungu ndi yayitali, nthawi zambiri imatenga masiku 20-35.

Kuzama kwa kutentha kwa LED kopangidwa ndi kuzizira kozizira kumatha kupangidwa mwazinthu zilizonse.

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.

Choyipa ndichakuti chifukwa cha kuchepa kwa njira yopangira, sikutheka kupanga zinthu zokhala ndi mawonekedwe ovuta.

Mwachidule, ngati kuwala kwa LED kumakhala ndi mawonekedwe ovuta komanso kuchuluka kwakukulu, tikulimbikitsidwa kugwiritsa ntchito njira yoponyera kufa, ngati choyimira cha kutentha kwa LED chili ndi mawonekedwe osavuta komanso ochulukirapo, tikulimbikitsidwa kugwiritsa ntchito njira yoziziritsa kuzizira,

Apo ayi, nthawi zambiri timagwiritsa ntchito extruded process kuchita.Panthawi imodzimodziyo, tiyenera kusanthula momwe zinthu zilili ndikusankha njira yoyenera kwambiri yopangira mtengo ndi ntchito zamalonda
