Performance Optimization of Cold-Forged Heat Sinks by COOLTEC
Cold-forged aluminum heat sinks stand out for their robust construction and precise fin geometry, ensuring optimal heat dissipation to the surrounding air. For applications with limited space and high thermal loads, COOLTEC enhances thermal efficiency through the targeted use of innovative heat pipes and copper inserts.
Integrated Heat Pipes
Integrated heat pipes accelerate heat transfer from critical hotspots to the cooling fins. Through a closed loop of evaporation and condensation, heat is evenly distributed – effectively supporting both passive and active air cooling systems.
Copper Inserts as Heat Spreaders
Copper inserts ensure uniform temperature distribution throughout the heat sink thanks to their excellent thermal conductivity. This minimizes local overheating and enhances thermal stability under heavy loads.
What Is a Cold-Forged Heat Sink?
Pinfin heat sinks are cold-forged air-cooling components with vertically oriented pins that create a particularly large surface area. This structure enables efficient convection – ideal for compact designs and multidirectional airflow applications.
The cold-forging process allows complex geometries with high material density. Combined with excellent thermal conductivity (e.g., aluminum EN AW-1050A or copper alloys), it results in a portfolio of cooling solutions that meet the highest thermal demands in the tightest spaces.

Frequently Asked Questions
Cold-forged heat sinks are made from aluminum profiles shaped using the cold-forging process. This method allows complex geometries with increased surface area for efficient heat dissipation.
The heat sinks feature thin fins or pins that provide a large surface area. The increased contact area with air improves convection and enables efficient heat removal from electronic components.
They offer high thermal performance, compact design, and flexible geometries. Cold forging allows for precise and varied shapes, making them ideal for applications with limited space.
The integration of pressed-in heat pipes and copper inserts as heat spreaders ensures faster and more uniform heat distribution, reducing hotspots and extending the lifespan of electronic components.
They are ideal for LED lighting, control electronics, power electronics, and industrial automation – especially where high thermal performance is required in compact designs.
