Pre-Cree CXB3070/3590/Citizen CLU048/058 /Bridgelux V22/V29
Pre drilled for Cree (35070/3590)/ Bridgelux (V22/V29)/Citizen (CLU048/049) are free， The material of our pin fin
heat sink is warm age-hardened aluminum alloy according to EN AW 99.5(Aluminum 1070) Our standard surface
treatments are raw degreased aluminum (Al) and black anodize (A3). On request, we anodize clear natural (A1)
or decorative in any color that is technically possible.
Splayed pin fin heat sinks are relatively new derivatives of the standard pin fin heat sink. Unlike standard pin fin heat sinks, which contain an array of vertically oriented pins, splayed pin fins features pins that gradually bend outward.Curving the pins in this way increases the spacing between the pins and allows surrounding air streams to enter and exit the pin array more efficiently without sacrificing surface area.he impact of increased pin spacing on heat sink performance is magnified at lower air speeds because weak air streams have less power to penetrate the array of pins.
In low air speed environments and in natural convection, the increased spacing between the pins reduces the
heat sink’s thermal resistance by up to thirty percent versus a standard pin fin heat sink. As a result, splayed pin fins are recommended for low and moderate airspeed environments and for natural convection cooling.
We believe that superior equipment makes for superior products,We believe strict quality pays off in the long run.
