Bondfin Bonded finned heat sinks

Extreme web ratios without limits thanks to inserted and specially joined ribs

  • Exceptional floor-bridge conditions

    Unlike conventional extruded heat sinks, there are virtually no limits with Bondfin technology. Minimal distances between the fins and high fins with low base thicknesses can be realised without any problems.

  • Optimal thermal management

    A large surface area and an excellent thermal connection between fins and base make finned heat sinks of any size suitable for demanding thermal management tasks.

  • Custom machining

    From machining to module assembly. Over 30 partially and fully automated 3-, 4- and 5-axis CNC machining centres enable the shortest cycle and delivery times. Various welding, soldering and bonding technologies enable the in-house production of complex heat sinks of all kinds.

Performance Optimization

The performance optimization of heat sinks maximizes heat dissipation, leading to greater efficiency and extended lifespan of electronic components. This allows devices to operate more stably and energy-efficiently, while also reducing failure rates. Optimized cooling also lowers operating costs and enhances overall performance in demanding applications.

Integrated Heatpipes

Integrated heatpipes improve the performance of air heat sinks by efficiently transferring heat from the heat source to the cooling fins. They work by utilizing a liquid inside the heatpipe, which evaporates upon contact with the heat source and transports the heat along the pipe. The vapor then condenses in cooler areas, releasing the heat to the heat sink, where it is dissipated by airflow. This rapid and even heat distribution boosts cooling performance and prevents overheating.

Copper Inserts as Heat Spreaders

Embedded heat spreaders, often made from alternative materials such as copper, are used to distribute heat optimally. Whether positioned directly beneath fluid-carrying circuits or in other areas, copper inserts enable more stable operating temperatures and extend the lifespan of electronic components.

Portrait of Benedikt Lausberg, Chief Executive Officer

Over 30 years ago, Antje Gornik and Martin Lausberg began producing extruded profile heat sinks and, as founders, laid the foundation for our company today. Today, profiled heat sinks are still an important part of our technology and product family.

Technology & Manufacturing

Brazed, bonded or welded finned heat sinks are innovative solutions for efficient heat dissipation in electronic devices and industrial applications. These heat sinks are characterised by their fin structure, which provides an increased surface area for improved heat transfer. With Bondfin, significantly more demanding base-web ratios can be realised compared to conventional extruded profiles. The permanent connection of the fins to the base plate is achieved either by soldering, welding or gluing, whereby both methods have their own advantages and areas of application.
