Feature
Standard pin fin heat sinks are relatively new derivatives of the Aluminum heat sink. Unlike aluminum extrusion heat sinks, which contain an array of vertically oriented pins, Standard 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.
The 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 forty percent versus a aluminum extrusion profile heat sink. As a result, pin fins are recommended for low and moderate airspeed environments
and for natural convection cooling.

Heat sinks are used to enhance heat dissipation from hot surfaces. A heat sink does this by increasing the surface area that is in contact with the cooling fluid or air.
From board level heat sinks, to LED heat sinks, to high power heat sinks,our goals are to provide you the best heatsink that is the most cost effective and highest quality. Our employees will see that we do whatever we can to make this happen.
