Inspired by customer inquiries, SEPA EUROPE has developed a new, modular assembly for the efficient cooling of chips. The core component is a SEPA axial fan that is mounted on a 40 mm pure aluminium heat sink – a so-called Kühligel®. It is equipped with a finger guard and a double-sided adhesive heat pad for screwless mounting on the housing or inside the device. Thanks to the compact design, the light weight and the screwless mounting, this assembly enables accurate positioning and thus effective cooling of the hot spot. The chip cooler HXB40FGK is equipped with a high precision ball bearing and can be used at ambient temperatures between -10 and +85 °C thus opening up a wide range of application possibilities. A further advantage is the long service life of the fan with 350 000 h (MTBF) at 40°C. The chip cooler assembly HXB40FGK is supplied as a standard component. It can however, be customized.

A roof fan can be the same name referring to two different types of fans. On the one hand, it is the classic fan that is mounted indoors in homes and spins around to create an air flow in a room (these are also called HVLS fans (High-Volume Low-Speed)). And partly it is the type of fans that we work with – i.e. fans that are mounted outdoors on roofs belonging to e.g. apartment buildings, schools or industrial premises. A roof fan is a fan that is part of the ventilation system and has the task of extracting hot air, moisture and pollution from the indoor space and blowing them outside. The fans are usually designed to be robust and weather resistant as they are mounted on the roof. Of course, there are a variety of material designs adapted to the application needs.

In the fluid dynamics laboratory of our Wasserburg competence centre, we design new fan wheels and turbines and optimise existing systems for performance, energy efficiency and noise emissions. We also develop complete systems of wheels with power units. Our range of tests includes suction operation, pressure operation and also unpressurised measurements. Revolutions up to 40,000 r/min and diameters of up to 250mm are possible. In our prototype department, we are able to simulate or modify the environmental circumstances of the fan wheels or turbines, thus achieving optimal operational conditions. Furthermore, we carry out mould-flow analysis, use ANSYS from external partners for the flow simulation and establish the fault probability and fault effect with FPFEs. New: Development of blower systems and optimization of ventilation systems.
