BONDED FIN HEAT SINKS AND FOLDED FIN HEAT SINKS

What is a bonded fin heat sink?

• Aluminum or Copper base and fins

• High thermal conductivity epoxy to attach fins to base

• Fin heights: .020 to 2.75 inch

• Fin widths: up to 24.0 inches

• Fin Densities: 4 to 38 fins per inch

• Fin material thickness: .008 to .032 (height and densities depends on thickness)

• Fin material types: Aluminum and copper

• .010" to .032" sheet aluminum or copper folded into fins

• Fin heights from .020" to 2.75"

• Fin widths up to 24.0 inches

• Fin densitites: 4 to 38 fins per inch

• The closest fins can be spaced is four times the material thickness

• Aluminum or copper base

• High thermal conductivity epoxy to attach fins to base

• Generally used  in forced air environments

• Ability to dissipate 2-3 times the heat load as an extruded heat sink of the same volume

• Can be used in both natural and forced convection applications

• Lightweight

• Increased surface area to cool more efficiently

• Uninterruptible power supplies (UPS)

• Variable speed motor controls

• Welding units

• Power rectification equipment

• Laser power supplies

• Traction Drives

• High density cooling of power modules

• IGBT's or transistors

• Telecommunications

• Motor Drives

• Automotive electronics
