Designed by Elektrosil: Intelligent seat cooling for cars

A proactive seat cooling in summer heat – with the development of the ventilation solution for passenger car seats, Elektrosil has demonstrated how complex and efficient such a technology can be.

The challenge

The customer wanted a sophisticated ventilation system based on condensation cooling. The requirements were clearly defined: High-performance, minimal noise and vibration, and robust material without plasticisers. The cooling should be effective, but not too powerful.

The solution

Elektrosil decided on a new development based on the required fitting dimensions. In comprehensive measurement and tests they confirmed the required ventilation system performance, cooling, noise level and minimal vibration. The behaviour of the individual components was agreed in close collaboration with the customer in a simulated installed state.

For intelligent control, the fan was incorporated via a LIN-bus interface and connected to the central controller and operating panel. In addition to the operating functions, the team also programmed various safety features. A great deal of skill was required when designing the printed circuit board: All components were positioned on just a few square centimetres, and EMC specifications and numerous design wishes were considered.

Furthermore, Elektrosil optimised the fan housing by adding a stable guard bracket for mechanically protecting the blower. This measure replaced the separate steel bracket which was previously required and therefore reduced the production costs.

“Superb – you can really count on Elektrosil!” The customer was impressed by Elektrosil’s commitment, flexibility and dedication.
