Custom Heat Sink-Stacked Fin Heat Sink
Folded fin heat sinks are specialized thermal management components designed to dissipate heat efficiently from electronic devices or systems. They are commonly used in applications where compactness, lightweight design, and effective cooling are crucial. The folded fin heat sink's distinctive design features fins that are created by folding and stacking thin sheets of thermally conductive material, such as aluminum or copper.
These fins significantly increase the surface area available for heat transfer, allowing for enhanced thermal dissipation through conduction and convection. The folded fin structure creates a labyrinth-like pathway for airflow, which improves the cooling efficiency by promoting better heat exchange between the heat sink and the surrounding air.
Folded fin heat sinks are particularly beneficial in situations where traditional finned heat sinks might be too bulky or inefficient due to space limitations. Their compact design and high surface area-to-volume ratio make them suitable for various applications, including high-power electronic devices like CPUs, GPUs, power amplifiers, and LED lighting systems. The folding of the fins also provides structural rigidity, helping to maintain the integrity of the heat sink while withstanding vibrations and shocks.

The Process of Heat Sink Production
Our Packaging
Our folded fin heat sinks offer thinner fins compared to extruded and bonded fin heat sinks. These lightweight folded fin heat sinks also deliver improved airflow while remaining cost-effective.
In the production of folded fin heat sinks, various fin shapes are affixed to a separate base, allowing the fins and base to be made from different metals. This type of heat sink configuration is especially advantageous when seeking a combination of lightweight, slim folded fins, and diverse base materials.
Our folded fin heat sinks, offered by Heatell, present an optimal solution for scenarios where a lightweight and thin folded structure paired with a dissimilar base material is required. By opting for our folded fin heat sinks, you can effectively reduce tooling costs and material expenses.
Our folded fin heat sinks boast fin thicknesses as low as 0.010 inches, heights reaching up to 1 inch, and inter-fin gaps spanning 0.060 inches. The soldering and brazing processes are executed within vacuum furnaces, ensuring impeccable quality. Furthermore, our folded fin design guarantees an elevated aspect ratio compared to traditional extrusions.
If you find yourself uncertain about which heat sink aligns with your specific needs, there's no need to worry. We extend a wide array of services encompassing detailed and conceptual thermal design, testing, prototyping, manufacturing, and consultancy for thermal management solutions.
