Custom Heatsink Types

Custom Machined Heatsinks
A machined custom heatsink uses GFSCNC's highly versatile machining capabilities. With low set-up costs, and machined custom heatsinks are ideal for low to medium volumes. Radian provides high precision machined heatsinks with complex features, contours, cut-outs and through-holes.

Custom extruded Heatsink
Aluminum Extrusions have conventionally been the predominant approach for low cost custom heatsink production.

Investment Casting, Casted custom heatsink
The Investment Casting process can cost-effectively produce complex custom heatsink designs in a short amount of time. Investment Casting is ideally suited for producing prototypes and short to medium volume runs.

Die-Cast Custom heatsink
Aluminum offers a cost effective Die-Cast custom heatsink solutions for medium, to large production volumes. GFSCNC uses Thermocast which is a proprietary technology to die-cast a high thermal conductivity Aluminum alloy with a thermal conductivity 0f ~160 W/m-k.

Custom Forged Heatsink
A Forged custom heatsink can be manufactured using special open die tooling and intense pressure to form thin-sectioned, high precision heatsinks. High aspect ratios can be achieved using Precision Forging.

Custom Skived Heatsink
A Skived custom heatsink combines special cutting tools and a controlled shaving technique to produce a heatsink from a single block of material, such as copper or aluminum. The typical result is a thin-finned heatsink, with a dense population of uniformly shaped and distributed fins.

Custom stamped fin heatsinks
A Stamped Fin custom heatsink is made from sheets of aluminum or copper, where the metal is stamped into a particular configuration based on the intended application. For maximum design flexibility, fins can be stamped into a broad range of geometries and thicknesses. A stamped Fin custom heatsink is a useful approach for medium to high volume production

Copper heatsink or Aluminum heatsink

The aluminum heatsinks are quite efficient in a variety of applications and very low cost, but there are circumstances in which the use of copper heatsinks is necessary due to the greater level of thermal conductivity one can achieve with it.

The copper heatsink conducts two times the amount of thermal energy as aluminum heatsink due to the material difference.Copper is able to be refined as a heatsink, put through die-casting and even bound together in the form of plates. However, there are certain downsides this metal, including it being more expensive, heavier and less malleable than the aluminum heatsink alternative. Furthermore, the production of extruded heatsinks is not possible with copper.

For this reason, the copper heatsink is worth mentioning that one very advantageous use of copper is found through the process of Skived Fin Technology. In this production method, a single block of copper is carved out of and ultimately a unified heatsink is created. The benefits to skiving copper are experienced through the increased efficiency created by having the heat source base attachment integrally connected to the cooling fins. In addition, copper's increased rate of thermal conveyance makes a skiving solution an extremely desirable heatsink design.

Another common alternative to all-copper heatsinks is the joining together of copper and aluminum in a single heatsink. This can be achieved by affixing multiple aluminum fins to a copper heatsink base. With this design for partially copper heatsinks, the designer will be rewarded by a high initial thermal transmission from the heat source which is then quickly conveyed to the aluminum fins. Such a system for copper heatsinks is ideal because it combines the benefits of both materials; while high conductivity is needed at the base of the heatsink, the light weight, extrusion capability and affordability of aluminum can be exploited by choosing this metal for use in the heatsink fins.
