Product information "Extruded Heat Sinks"
Broad variety of profile geometries; Width 15 mm to 473 mm; Height 11 mm to 135 mm; Rth 0.019 °C/W to 3.347 °C/W; Weight 0.249 kg/m to 30.80 kg/m
Extruded aluminium heat sink profiles are safe for a lifetime, as fins and base plate are a single piece extrusion. The aluminium extrusion process can be used to produce a large number of different profile shapes. With modifying the profile shape, the surface that comes into contact with the air is also changed, and thus the ability to dissipate heat. Extruded heat sinks are mainly used in systems with medium electrical power, both with natural and forced convection by fans. The heat sinks utilise different surface enlargement geometries to match pressure head and flow rate of fans and blowers.

Bonded Fins Heat Sinks
Basic carrier profile fitted with cooling fins using bonding technology; Width 200 mm to 500 mm; Height 84 mm to 180 mm; max Length 700 mm; Rth 0.039 °C/W to 0.040 °C/W; Weight 25.55 kg/m to 46.55 kg/m
Bonded fins heat sinks are characterized by a special joining technique in which the fins are applied to the base of the heat sink using a highly thermally conductive epoxy resin. Designed for forced convection applications, this family of heat sinks offers high thermal performance with maximum dimensional flexibility. Bonded fins heat sinks do not require a special extrusion tool as they are made from standard metal sheets and plates. They also offer the possibility of combining different materials such as copper and aluminium.

Brazed Fins Heat Sinks
Basic carrier profile fitted with cooling fins using brazing technology; Width 200 mm to 1000 mm; Height 85 mm to 132 mm; max Length 1,000 mm; Rth 0.011 °C/W to 0.06 °C/W; Weight 17.85 kg/m to 78.51 kg/m
Not always does one of the many extruded, monolithic standard aluminium profiles meet the requirements of a very special heat dissipation project. Therefore, a production technique in which a basic carrier profile is fitted with cooling fins using brazing technology offers particularly flexible possibilities for manufacturing a customer-specific heat sink. Depending on the requirements of the project, different alloys can even be used without the limitations typical of extruded profiles. There is no need to design and manufacture new extrusion dies, nor are there any restrictions on size, overlong delivery times or minimum order quantities. This technology offers maximum flexibility and short response times in prototype and series production. Contact us or send us a request for a comprehensive consultancy for your custom brazed fins heat sink solution.

Clip System Heat Sinks
Ideal for cooling TO-220, TO-247 or similar package types; Width 36 mm to 75 mm; Height 19 mm to 40 mm; Rth 0.673 °C/W to 2.448 °C/W; Weight 0.76 kg/m to 2.61 kg/m
Heat sinks that are designed for being mounted with a clamp clip are mainly used for cooling power semiconductors in TO-220 or TO-247 packages or similar package types, mounted on a printed circuit board (PCB). Compared to a conventional screw-based assembly system, the clip system can provide similar thermal resistance values between the component and the heat sink. At the same time, however, it offers clear technical advantages, especially for the assembly process. Clip systems not only ensure a central, even contact pressure on the semiconductor component, but also simplify initial assembly as well as disassembly and re-assembly for maintenance purposes. Contact us now to find out more about our line of heat sinks allowing mounting electronic devices with a clamping clip.

Heat Sinks for Double-sided Mounting
Profiles can carry power semiconductors on two opposite sides; Width 64 mm to 180 mm; Height 45 mm to 105 mm; max Length 300 mm; Rth 0.020 °C/W to 0.2 °C/W; Weight 2.6 kg/pc. to 5.25 kg/pc.
Some extruded aluminum heat sink profiles are designed in a way that heat sources can be mounted on both heat sink bases while forced air from a fan or blower flows through the hollow heat sink with internal fins. A narrow fin spacing provides the necessary very large cooling surfaces. This kind of heat sink profiles for double-sided mounting is available in lengths up to 300 mm. For detailed information on heat sinks for double-sided mounting and the many options for defining a custom solution, please contact us.

Special Profile Heat Sinks
Highly configurable to meet custom specifications; Width 100 mm to 800 mm; Height 40 mm to 135 mm; max Length 3,000 mm; Rth 0.008 °C/W to 0.028 °C/W; Weight 5.21 kg/m to 144.42 kg/m
Selected manufacturers are able to offer fully customised heat sinks using special profiles, but with specifications of standard solutions. Both mechanical mounting of base plate and cooling fins as well as monolithic construction are available as manufacturing processes. In this way, good thermal conduction can be achieved with customer-specific mechanical dimensions. The achievable thermal resistances are at least comparable with those of the widely used standard profiles. Our thermal management specialists will be happy to help you design a tailor-made solution for your project. Contact us or send us your request for a customized solution.

Welded Heat Sinks
Ideal for cooling TO-220, TO-247 or similar package types; Width 36 mm to 75 mm; Height 19 mm to 40 mm; Rth 0.673 °C/W to 2.448 °C/W; Weight 0.76 kg/m to 2.61 kg/m
By joining two or more extruded standard profiles by friction stir welding, robust, stable finned heat sinks with widths of up to 1000 mm can be produced. This manufacturing process can be very flexibly adapted to custom dimensional requirements and can be used for many modifications to standard extruded profiles. While friction stir welding has the advantage that no additional welding material is required, we can also provide special profiles that are pre-bevelled during production and which thus allow an efficient TIG or MIG welding process. Please contact us for detailed information on the selection of profiles that can be joined together through welding process.
