Who is  E-Cooling?

The engineering consultancy company E-Cooling was established in Berlin by  Karim Segond. The E in E-Cooling stands for Electronics, Electricity and Electric Motor.
Ventilation engineer Guenter Zwarg is our expert for heating and cooling of electrical machines while Dr. Guenther Siegl is our expert for the machine dynamics, vibrations and acoustics. We are also partner of the expert network for electrical machines SCO Expert Pool

We are flexible

We work with you to determine the planning and objectives, and perform the calculations ourselves. We are flexible to customer needs: the project can be offered with various options and deadlines can be adjusted based on the project progression. The following options can be arranged: - Training of employees - Software independent consulting regarding calculation methods - Setting up initial simulation model - Handover of the model to the customer for parameter variation calculations - Comparison with test results …

Magnetic field

We can offer magnetic field calculations for a new design or a power increase analysis. The calculated losses are the input of thermal calculations. We calculate the magnetic field of electric machines with Finite Elements in 2D or more detailed and complex in 3D.

Ventilation and cooling of electrical machines

We offer detailed analysis, improvement of existing products or development of new ones, trouble-shooting as well as an expert opinion for problem cases, non-conformities and turnover. We assist in the preparation and evaluation of the corresponding measurements.
In the concept phase or for a fast diagnosis we use flow and thermal networks; for a more detailed design we recommend 3D-CFD thermal and flow calculations.

3D flow Simulations

We are capable of working with any CFD tool; however we prefer to work with software based on cartesian mesh like FloEFD or FloTHERM, as with these it is possible to set up easy and fast heat transfer cases; the resulting costs and price are correspondingly low.
Usually we generate the CAD model with Solidworks. We can either work from our engineering office in Berlin or directly on-site with the customer.

Machine dynamics

We solve the problems of rotating machine dynamics and its interaction with the environment (bearings, complete drive trains, foundations, locomotives and rails) from our experience of own- programming, for the stationary as well as for the transient cases.

Recorded Webinar:
Power Electronics Cooling Calculation at Room Level
you will learn: - what does Room Level mean, - how to asses the working point of a fan, - how to asses the cooling and heating without calculating the heat transfer with the flow.
