China Aluminum Heatsink for LED and Electronics (YLJ70991)
A majority of aluminum extruded heat sink currently in production are made using finned aluminum extrusions. Aluminum is lightweight, has high thermal conductivity and is easily customized & machined to fit a wide variety of applications. Recent improvements in extrusion tooling and pressing processes allow far greater fin density, more cooling surface, than was available just a few years ago. Increased cooling surface with proper air flow reduces semiconductor junction temperatures, increase power output and increases system life.
Standard features of aluminum heatsink:
Best value cost option for high volume production
Ultrahigh extrusions give maximum cooling area with single piece construction
New custom designs are relatively inexpensive to tool
May replace bonded fin parts at lower cost
Various low cost surfaces finishes offer cosmetic and corrosion protection
Design Guidelines
Typical extrusions fit within an 8.0 inch tooling diameter
Larger extrusions, up to 16.0 inch diameter tool, are available
Common extrusion material is 6063-T5 ( k = 201 W/mK)
Ultrahigh extrusion ratios up to as much as 20:1, size dependent
Fin thickness down to 0.020" (0.50 mm) depending on height above base.
Standard commercial extrusion tolerances apply to extruded features.
Many existing tools offer rapid prototypes / short run parts.
