LED Cold Forged Heat Sink Characteristic

Kugadzira uye kudzvanya pane tembiricha yekamuri (yakaderera pane tembiricha yerecrystallization yesimbi) inokonzeresa kurongeka kwepamusoro muchimiro chechigadzirwa uye saizi, kunaka kwemukati density, kusimba kwepamusoro, nzvimbo yakatsetseka, uye mashoma ekugadzirisa matanho, zvichiita kuti zvive nyore kugadzirwa kwakakura.

1. Good thermal conductivity

Cold forged heat sinksinogona kubudiswa uchishandisa yakachena aruminiyamu AL1070 uye 1050 muchidimbu chimwe.Thermal conductivity ye pure aluminium AL1070 is 226W/mk, alloy aluminium (6063) ine thermal conductivity ye180W/mk, nepo yakajairwa die cast aluminium (A380) ine thermal conductivity ye 96W/mk chete Iyo yakakura thermal conductivity, iyo nekukurumidza kupisa kunoburitswa ne LEDs kunogona kufambiswa, izvo zvinonyanya kubatsira pakupisa kwese kwemarambi e LED.

2. Zvisarudzo zvezvinhu zvakawanda

Iyo inotonhora yekuumba mold inogona kushandisa AL1050 akatevedzana zvinhu, kana AL6063 akatevedzana zvinhu kugadzira heatsinks.Izvo zvinhu zviviri zvinogona kugovera seti yezviumbwa kuwedzera sarudzo dzevatengi uye kusangana nezvinodiwa zvakasiyana!

3. Yakanakisa kupisa kupisa chimiro

Iyo base plate (yepasi ndiro) yeinotonhora forged heatsink inoumbwa pamwe chete nemafins, uye hapana gaka pakati pavo.Iko kupisa kubva kune substrate kunogona kuendeswa kune kupisa kupisa zvimbi pasina kuvhiringidza.Zvisinei mamwe akasungwa kana brazed kupisa sinks, ane kupisa kupisa substrate uye kupisa dissipation zvimbi zvinorivheterwa kana brazed pamwechete mushure mekugadzira, anofanira kunge ane maburi pakati pawo;Iyo indirect thermal resistance inogadzirwa.Panguva imwecheteyo, kuwedzera kwekushisa panguva yekushandiswa kwemarambi kuchaitawo kuchizvarwa uye kuwedzera kwezviputi, izvo zvichawedzera kupisa kwekushisa uye hazvibatsiri kupisa kupisa.

4. Chimiro chechigadzirwa chisina kujairika

Nzvimbo dzepamusoro uye dzepasi dzeplate yepasi dzinogona kuumbwa kuita anisotropic zvimiro kuburikidzainotonhora yekuumba tekinoroji, uye mativi maviri anogona zvakare kudhindwa kuita akakosha maumbirwo

5. Nzvimbo huru yekupisa kupisa

Ukobvu hwemafins ekupisa ekupisa kweinotonhora yekugadzira singi yekupisa inogona kusvika 0.7mm, uye nzvimbo yacho inogona kusvika 1mm.Iyo yakaonda uye yakawanda inopisa kupisa zvimbi inowedzera zvakanyanya nzvimbo yekusangana nemhepo, iyo inonyanya kubatsira kune mhepo convection uye kupisa kupisa.

6. Zvimbi zvakasiyana-siyana

Iyo inotonhora yekugadzira nzira inogona kusangana neakasiyana maumbirwo ezvimbi, senge cylindrical, sheet rakaumbwa, square column, hexagonal column, nezvimwe.

7. Hukuru hukuru hwekupisa sink

Iyo inotonhora yekuumba maitiro uye yemhepo yekumanikidza midziyo inopfuura mazana matatu ezviuru matani inogona kuumbwa mune imwe kuenda kusangana nehukuru hukuru hwe260 * 260 kana kupfuura,

8. High aspect ratio

Chiyero chechiyero cheanotonhora forged heatsinks chiri pamusoro pe1:50, nepo extrusion yekupisa sink inowanzo kutenderedza 1:25.

9. Multi directional inlet uye outlet mhepo

Iyo mhepo inopinza uye yekubuda nzira yeinotonhora yekugadzira heatsink ine matatu-dimensional.Ordinary extrusion ndeye maviri-dimensional inlet uye outlet mhepo inoyerera kuti igadzirise zvirinani kunharaunda uye kuwana zvirinani kupisa kupisa.

10. Structural anisotropy

Iyo inotonhora yekugadzira kupisa sink inoumbwa nekugadzira uye nekutsikirira mold, saka inogona kugadziriswa pane mold kuti ive nechokwadi chekuonekwa kweheterostructure kuseri kwe substrate, kuitira kuti ibatane zvirinani nechinhu chinopisa.

11. Ukuru hudiki uye uremu huremu

Kuenzaniswa nekufa-kukanda,extrusion heatsinksuye zvikamu zvebrazed, yakachena aluminium inotonhora yekupisa inonyura ine zvakanakira zviri pamusoro.Vhoriyamu imwechete uye maumbirwo ekupisa anonyura anogona kushandiswa kupisa kupisa kwemarambi ane simba-akakwirira (senge echinyakare 5W heatsinks, nepo aruminiyamu yakachena yakagadzira heatsinks ine vhoriyamu yakafanana uye chimiro chinogona kuwana 7W).Naizvozvo, kushandisa yakachena aruminiyamu inotonhora yekubikira kupisa sinks kunoderedza huremu uye vhoriyamu yemarambi eLED, kuderedza zvinodikanwa zvekutaridzika senge mbiru dzemwenje, uye kuwana kudzikiswa kwemutengo wakazara, zvichiita kuti chigadzirwa chiwedzere kukwikwidza!

12. Chitarisiko chakanaka

Iyo heatsink zvinhu ndeye aluminium, uye iyo yepamusoro inogona kudzorwa kuti iwane yakatsetseka uye yakanaka kutaridzika.Mavara akasiyana (sirivha, chena, dema, nezvimwewo) anogonawo kudzorwa zvinoenderana nezvinodiwa nevatengi.Iyo yepamusoro ye-die-casting aluminium yakaoma uye inoda kupfapfaidza kurapwa, iyo isingakodzeri kupisa kupisa.

13. Kuita kwepamusoro

Yakakwira conductivity, yakakwira dimensional kurongeka uye kugadzikana, kuita kwakagadzikana, uye nyore kurapwa kwepamusoro.Zvinoenderana nezviyero, kupisa kwekudziya kwealuminiyamu inotonhora yekubikira kwakakwirisa kakapetwa kaviri pane iyo yemhando imwechete yezvigadzirwa zvinofa, uye ka1 yakakwirira kupfuura yemhando imwechete yezvigadzirwa zvealuminium profiles.Parizvino ndiyo yakanakisa mhinduro yekupisa kupisa kwepamusoro-simba ma LED mwenje zvigadziriso.
