Thermal heat sink simulation saves time and money

How we use thermal simulation to cool your electronics in a cost-optimised way
Preventing performance losses and heat death
This can quickly become very expensive if prototypes or even series devices become too hot during operation and time-consuming development steps have to be repeated.
With thermal simulation in virtual environments, EKL offers you a realistic method to run through a variety of best-case and worst-case scenarios in the shortest possible time - and without using any materials. Our specialisation in electronic heat sinks and 30 years of experience in their development and production helps us to approach the selection of alternative coolers for the simulation in a targeted and results-oriented manner.

State-of-the-art simulation software based on CFD methods
As a result, you receive a selection of cooling solutions that provides you with a valid basis for decision-making based on parameters such as
- Size
- Production technology
- design
Simulation of heat sink alternatives in the system design
- Size reduction with the same performance
- Changed arrangement of components on the circuit board / in the device
- Size and number of ventilation slots in the housing
- Optimisation of air intake and air removal
Example simulation: Material comparison of a forced-cooled finned heat sink


Evaluation and basis for decision-making

Your advantages of simulating heat dissipation processes:
- Early detection and elimination of thermal problems
- Varying the materials and fans
- Determination of a cost-optimised cooling solution
- No material and prototype costs
- No unnecessary development loops and additional labour costs
- No unnecessary loss of time in the time-to-market
Example simulation: Increasing cooling capacity by comparing alternative manufacturing processes




Evaluation and basis for decision-making

Example simulation: New product development with early inclusion of the cooling solution
Especially if you want to offer a device in different performance classes. Low power generally generates less power loss that needs to be cooled. This allows you to install a less expensive cooling solution, which is reflected in a more favourable product costing.
If the performance of the device increases, the cooling capacity and cost increase should remain in balance. Your electronic product should not only function reliably, but also remain competitively priced.
Variation of component design and cooling solutions

Large heat sink with long fins
One fan on the heat sink
An additional fan on the housing
5 x Ø6 mm heatpipes
(long heatpipes = power loss)

Shorter heat sink = less pressure loss
The additional fan has now been mounted on the heat sink
5 x Ø6 mm heatpipes
(shorter heatpipes = less power loss)

Shorter heat sink (less pressure loss)
The additional fan has now been mounted on the heat sink
2 x Ø6 mm heatpipes
3 x Ø8 mm heatpipes

Get to know more EKL expertise
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!
