Advanced Thermal Solutions Zipper Fin Heat Sink

High Fin Density Heat Sinks, Pre-Tooled, No NRE

Advanced Thermal Solutions provides pre-tooled zipper fin heat sinks engineered for high-efficiency cooling and cost savings, particularly in large-scale production. These lightweight solutions offer a reliable alternative to conventional high-density heat sink designs and come with no non-recurring engineering (NRE) charges.

Crafted from stamped aluminum or copper sheets, the interlocking fins are formed and securely attached to a metal base, creating an effective thermal interface. A typical design pairs a copper base with aluminum fins to achieve optimal heat spreading with minimal weight. The use of high aspect ratio fins increases the available surface area, enhancing heat dissipation.

For applications requiring active airflow, these zipper fin heat sinks can be customized with heat pipes or integrated ducts. In such setups, the base acts as the evaporator while the fins serve as the condenser, delivering a lightweight and high-performance thermal management solution suitable for demanding electronic systems.
