Extruded Heat Sinks

Extruded heat sinks are the most common heat sinks used for thermal management. Extruded heat sinks are generally used in medium power systems both in natural and forced convection. The extrusion process, pushing hot raw aluminium through a steel extrusion die to create the desired profile allows for innumerable complex shapes to be manufactured. Many standard shapes are available but modifying the profile shape changes the surface in contact with the air and consequently the heat dissipation capability. Fodor Technology can supply standard profiles or engineer a heat sink shape to achieve optimal performance in the space available. After cooling and ageing, the material is cut to the final heat sink length and any additional features such as holes or pockets can be added.

Extruded heat sinks can be supplied raw or with a finish, such as anodizing, electrophoresis or powder coating. Certain finishes can alter the emissivity, which can enhance thermal performance.

We have some existing aluminum extuded molds, if you need further detail information, please send inquiry to us.
