Zipper Fins Heat Sinks

Zipper fins provide greater flexibility in design and high aspect ratios. They are economical for larger production runs.
Strong structural stability, both top and bottom fins interlocked. Reliable mechanical support, fins held together on top and bottom.
Bespoke integrated systems with fans, ducting, and heat pipes. Enhance performance. Suitable for high-performance applications with larger production runs.
Zipper Fin heat sinks are perfect for air cooling high-powered forced convection applications at large scale production. Employing interlocked sheet metal fins that are stamped, folded, and zipped together in the zipper fin stack. The length of fins and gaps in the stack can vary by stamping dies, and fins can be open or closed according to airflow needs.

What are Zipper Fins Heat Sinks

Zipper fin heat sinks, also known as zipper fin heat sinks, are a cooling technology primarily used in electronic devices to manage thermal performance. They are designed to maximize surface area and enhance airflow for more efficient cooling. Zipper fin radiators are made from thin sheets of metal, usually made of aluminum or copper. These pieces of metal are stamped or machined to create an interlocking "zipper" shape. The fins are then assembled mechanically, allowing them to interlock or "zip" together to form a dense array of fins with a high surface area. The interlocking fins are usually attached to a solid base plate, which is also usually made of a thermally conductive material, such as aluminum or copper.
