Ultra-high fin density for maximum thermal performance.
Zipper Fin heat sinks use individual stamped fins mechanically zipped together and bonded to a base. The result is very high fin density and aspect ratio in a compact envelope — ideal where every degree of ΔT matters.
The product range
A closer look at the materials we supply.
Individual aluminium or copper fins stamped and zipped together for a very high fin density.
Fin stack soldered or epoxy bonded to a machined base tailored to your component footprint.
Fins folded into a 'C' profile to form an integral airflow duct for optimised forced convection.
Fins pressed onto embedded heat pipes to spread heat evenly across the full stack.
High fin density
Pack more surface area into the same footprint than folded or extruded designs.
Large aspect ratio
Tall, thin fins increase surface area without stealing board real estate.
Strong forced-air performance
Optimised for use with fans or system airflow — very low thermal resistance.
Flexible geometries
Base sizes and fin heights tuned to your specific thermal and mechanical envelope.
Copper or aluminium
Material choice to balance thermal performance, weight and cost.
Combine with heat pipes
Embed heat pipes in the base to spread heat evenly across the fin stack.
Key benefits
- Maximum surface area per unit volume
- Aluminium or copper construction
- Optional embedded heat pipes
- Custom base geometries to your drawing
