Swaged cooling fins for large aluminium heat sinks
Profile heat sinks connected in series
Swaged cooling fins, also known as swaged cooling fins, are an essential part of the heat dissipation of large electronic components. They are manufactured using an extruded aluminium heat sink, which can be taken from a standard range or customised, depending on requirements. This profile is then pressed together several times in a process known as swaging. This allows not only the length to be customised, but also the width to be scaled as required without additional tooling costs. Profile heat sinks with optimum thermal conductivity and a large surface area can be produced cost-effectively.
Advantages of swaged heat sinks
- Scalable length and combination of different profiles possible
- Good thermal conductivity
- One-off tool costs with customised profile
- Various surface finishes possible
(anodising, chromating, painting, powder coating, etc.)

Added value and extras
Our full service goes beyond the mere development, series production and logistics of your heat sinks. Do you need special holes or milling on your heat sinks? Do you want your heat sink to not only dissipate a lot of heat, but also look stylish? Would you like a product ready-to-plug-in with all accessories?

CNC machining
For prototype construction, small series and customised reworking of heat sinks, we have modern 3- and 5-axis CNC milling machinesat our company headquarters. Complex machined and high-precision radiators are our speciality. Working areas of the machines:
Hermle C 400 (5-axis) 850 x 700 x 500 mm | Mikron VCE1000pro (3-axis) 1000 x 560 x 600 mm | Kondia B1050 (3-axis): 1000 x 500 x 600 mm

Surface finishing
Our range includes various surface finishes to create a durable, corrosion-resistant surface. Nickel plating increases wear resistance and lustre. Chromating and passivation, especially with Surtec 650, provide additional protection against corrosion. Powder coating is another option for a robust and durable coloured surface. Painting and cathodic dip coating round off our wide range of surface colours and textures.
Attachments & accessories
Depending on the application, screws, springs or push pins ensure the secure and stable attachment of the heat sinks. Backplates provide additional stability and improved heat dissipation. Heat-conducting pastes and pads are naturally part of our range to enable optimum heat transfer between the heat sink and the heat source.
Secure packaging for transport
With a focus on optimum protection during transport, we develop packaging that not only fits perfectly but is also robust. Another important aspect of the range is the use of recyclable materials that contribute to sustainability and environmental friendliness.
Swaged cooling fins in typical areas of application
Due to their scalability, pressed aluminium heat sinks are particularly suitable for combining with other cooling technologies. They optimally utilise the physical effects of convection, heat conduction and heat radiation to dissipate heat from electronic components. By integrating them into a comprehensive cooling system that includes liquid cooling or Peltier elements, for example, the overall cooling capacity can be significantly increased.

The EKL project stages for your cooling solutionChoose your entry point!
Our offer is as flexible as your needs. Are you still early in the development phase and want an idea generator for the best cooling solution? Do you have a ready-made device that gets too hot? Or are you simply looking for an alternative or additional supplier for a heat sink already used in series production? In EKL you will always find a flexible, agile and responsible partner for the cooling of your electronic components and complete systems, whatever the project phase. We look forward to your enquiry!
Counselling
Concept
Concept
In personal contact and open dialogue with you, our engineers create the creative space and framework to design the best cooling solution for your requirements from the wealth of options available.
Development
Feasibility / simulation
Feasibility / simulation
We test the idea for your heat sink virtually in the thermal simulation. Realistic computer simulations allow variations in manufacturing processes, system structures and other parameters.
Performance optimisation
Even a well-functioning heat sink can still be optimised. We determine the "how" and "how much" by simulating different materials or cooling technologies, for example, as well as simulating various environmental parameters.
Cost optimisation
An expensive heat sink can often be made significantly cheaper by using an alternative manufacturing process. Whether with the same or application-specific performance: we support your product development in reducing costs.
Production drawing
Prototype construction
Prototype construction
Prototypes from our design department enable early testing and targeted solutions to problems in your device. We create your functional and design prototypes with our in-house CNC production.
Series production
small to large
small to large
By manufacturing in-house and in Asia, we can offer all types of heat sinks from small to large series at competitive unit prices. We impress our long-standing customers with our consistently high quality.
Sampling
Incoming goods inspection
Incoming goods inspection
We make no compromises when it comes to quality: Development takes place in Germany and all series products are analysed by our German test laboratory according to test plans using state-of-the-art methods.
Surface finishing
Anodising, powder coating, painting etc. protect your heat sinks from corrosion and environmental influences. But colour is not just chic, because dark-coloured heat sinks also emit more radiant heat.
Assemblies
Pre-assembly
Pre-assembly
We actively relieve your production with pre-assembled assemblies. This reduces your workload per device and guarantees the highest quality, because as cooling professionals we ensure that the heat sink is optimally attached.
Quality assurance
Test plans
Test plans
We test according to our own and customer-specific test plans using the latest rapid thermal measuring equipment, 3D measuring machines, assembly tests and testing of various application scenarios.
Packaging design
Packaging production
