High performance heat sink customised and cost-conscious for your product
Features of modern high-performance heat sinks
Outstanding cooling performance at manageable costs is achieved with modular heat sinks, which are designed by combining standard modules in a performance-orientated and cost-conscious way. This results in customised units, for example with densely arranged cooling fins and long, thin fins. These heat sinks are compact yet have a very large surface area.
Depending on the requirements, EKL combines various production methods to join the modules into an efficient heat sink, including bonding, pressing, soldering, skived fins and friction stir welding.
If the calculated cooling capacity is still not sufficient, embedded heat pipes or liquid heat sinks can be used to achieve the desired power dissipation.

The advantages of modular EKL heat sinks:
- Wide range of standard modules available
- Customisable to your specific application
- Customised solution with minimal or no tooling costs
- Combination of aluminium and copper materials possible
- Low thermal contact resistance
- Cost-effective alternative to heat sinks with liquid cooling

Examples of coolers from EKL's manufacturing technologies
Bonded fins
The connection between the base plate and the fins is made using a special adhesive. The special adhesive is cold-curing and therefore avoids possible material distortion... Learn more
Embedded heatpipes
The thermally highly conductive copper tubes work by means of phase change of the contained medium and can effectively and very quickly dissipate hotspots in your system to a suitable heat sink... learn more
Pressed cooling fins
An extrusion profile serves as the basis for the swaged process (pressed cooling fins). Depending on the complexity, either a standard or a customised profile is used. This profile can then be pressed together as often as required... Learn more
Friction stir welding (FSW)
In friction stir welding, a rotating pin is pressed into the butt joint of two cooling profiles and moved along the joint line. The material is heated by the friction and stirred by the rotation of the pin so that the materials join in a hot forming process.
Liquid heat sinks
A significant improvement can be achieved with heat sinks through which liquid flows. Due to their good thermal conductivity, copper or aluminium alloys are used as the plate material. To further reduce thermal resistance, the plates are made as thin as possible and have many channels running through them.
Skived fin heat sinks
The "scraped" ribs are seamlessly connected to the base plate and thus guarantee high-performance heat transfer. Even small batches can be realised thanks to inexpensive tools.
EKL: Your specialist for economical high-performance cooling
To keep your product innovations in the ideal temperature range, we offer efficient heat sink modules that ensure excellent heat dissipation. In addition to heat pipe solutions, pressed or bonded cooling fins, friction stir welding and skived fin heat sinks, liquid heat sinks are also an excellent option.
With over 30 years of experience in cooling high-performance electronic assemblies, we are your reliable partner. When designing the ideal cooling solution for your application, we not only take into account the cooling capacity required from the available installation space. Depending on the required quantity, we design not only the best but also the most cost-optimised cooling solution for you.

High-performance heat sinks in the application
High heat generation must be counteracted by efficient cooling, particularly in the areas of power electronics. This includes
- Cooling of diac (bidirectional diode) when controlling thyristors
- Cooling of bipolar power transistors used in switching power supplies and DC/DC converters
- Cooling of power MOSFETs (metal-oxide-semiconductor field-effect transistors), which are also installed in switching power supplies and DC/DC converters
- Cooling of GTO thyristors (IGCT) in high-power converters
- Cooling of semiconductor switching devices in general, such as transistors, diodes and thyristors, which are considered essential components in power electronics
- Cooling of circuit types such as rectifiers, inverters, DC/DC converters and DC/AC converters, whose reliable function is of central importance in the field of renewable energies and electromobility

EKL - Everything from a single source
The temperature of electronic components must remain within the tolerated range, as excessive heating can shorten their service life and impair their performance. EKL provides you with expert support in solving these heat problems efficiently and economically using passive heat sinks, fans, heat pipes, liquid heat sinks or other thermal management technologies.
EKL is therefore your perfect solution partner for cost-optimised temperature regulation of all components in your electronic device. We are at your side in every project phase, from the initial idea, design and prototype construction through to series production - and beyond!

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.
