Catalogue of Standard Profiles for Heatsinks

Custom Machining and Surface Treatment on Demand

Extruded and machined (CNC) heatsinks to dissipate heat from an electronic component or assembly

Standard Extrudes Heatsink - Profil de dissipateur standard - Compelma

About heatsinks for electronic projects:
Using a standard extrusion profile for your heatsink is a good balance between custom and standard production. The profile of the heatsink is used to extrude the raw heatsink. Then we use CNC to adapt it to your specification and to your mechanical setup. When the heatsink is finished, we can add a surface treatment (Surtec 650 or anodization).
Keep in mind that Surtec 650 protects against oxydation AND is conductive. Surface treatment with anodization is not conductive.
‍
We can deliver the part directly assembled with the fitting thermal interface. Or delivering the thermal interface apart, with the right dimensions. using a thermal interface material between the heatsink and the component will ensure a full contact between the component and the heatsink (without air, which is a thermal insulator). You can also consult our article about how to choose the best thermal interface material.
If you do not find the profile fitting for your project, get in touch with us. We can design the profile reaching your thermal target with the required dimensions. We can deliver a thermal report on demand.
Compelma provides heatsinks from prototyping to mass production.
