01.10.2018 - Practice-oriented introduction to the cooling of electronics and components

Practice-oriented introduction to the cooling of electronics and components.

Due to the extremely rapid development in all areas of technology, we consider it necessary to re-issue the technical book on „Thermal management for electronic components“ written by Heinrich Cap of SEPA EUROPE. The second edition was comprehensively updated and supplemented and now includes new findings and knowledge relating to state-of-the-art technology.

The volume gives insight into the world of electronics cooling, presents modern ventilation concepts and covers aspects such as noise behaviour and reliability. It provides interesting basic knowledge on active and passive cooling, cooling via heat sinks and much more. Further contents include real-life applications and examples as well as tips for choosing the correct fans.

This indispensable handbook provides the reader with in-depth knowledge of thermal management and is therefore a must-have for all those who require a ready-to-hand extensive guide.

The book is also available in bookshops.

Cap, Heinrich: Wärmemanagement bei Elektronischen Bauteilen (Thermal Management for Electronic Components. Format 17 x 22.5cm, 80 Pages, Hardcover, ISBN 978-3-88778-549-9,

Retail price: 9.80 €.

25.09.2018 - Intelligent solutions for LED cooling by SEPA EUROPE

Passive cooling solutions are usually too big. Small active heat sinks are the ideal solution.

Stable light colours, a high life expectancy and low energy requirements are the unbeatable advantages of LED technology. However, whereas the energetic superiority comes virtually automatically, considerable investment must be made in thermal management to fulfil the demands on the colour values and service life. Only well cooled diodes can keep what they have promised in the long run.

For optimum thermal management, SEPA EUROPE offers not only passive cooling solutions but also active heat sinks. Active cooling concepts usually provide the ideal solution when space is a problem. They are smaller and lighter, can attain the desired service life, are attractively priced and find space virtually everywhere.  SEPA EUROPE already supplies its customers with fans that are adapted to the application in question and in some cases with special waterproof fans.

The cooling experts at SEPA EUROPE will gladly assist you in selecting the correct fan, the design and series production that you require.

04.09.2018 - Varied selection of guards with quick delivery guarantee

SEPA EUROPE, the experts for customized cooling solutions meets the highest expectations with its wide range of guards for axial fans.

Modern high-performance fans operate at high speeds which increase the risk of injury. To enhance safety, SEPA EUROPE offers guards for axial fans in every required dimension.

The well-designed guards of SEPA EUROPE are not only extremely stable but also improve the appearance of each fan. The high-quality surface (chrome-plated, powder-coated, zinc-plated or pure stainless steel V2A or V4A) stands for a longer service life and extensive protection against corrosion. We perfect the product with excellent finishing and a flawless surface without sharp edges.

Additional advantage: The guards of SEPA EUROPE are aerodynamically optimized so that the fans can operate with optimum efficiency.

A further advantage is the simple mounting by screwing to the fan. It is not absolutely necessary to mount the finger guards directly on the fan as they can also be mounted directly on the fan housing irrespective of the size.

The standard guard sizes are available in 25 mm to 220 mm diameter in chrome-plated steel. Each required dimension is available in correspondingly large numbers.

SEPA EUROPE can offer maximum delivery reliability for the guards as standard guards are as a rule available immediately in large numbers ex stock.

09.05.2018 - New sleeve bearing fans with MagFix system for temperatures up to 85 °C

As the need for fans that are used in applications subject to high temperatures is constantly on the increase, SEPA EUROPE – the fan and cooling specialist – is presenting its latest sleeve bearing fan equipped with MagFix technology that can be used for operating temperatures up to 85 °C. An added advantage is the extraordinary high life expectancy of 210.000 h (MTBF). This fan is not only available in the standard sizes but also as a tailor-made solution.

With the high operating temperature of up to 85 °C, this innovative fan generation by SEPA EUROPE opens up a wide range of new applications for the user, not least the automotive sector. The term MagFix stands for magnetic fixation (positioning) of the fan propeller/rotor in sleeve bearing fans.

The sleeve bearing as used in fans only allows for a positioning of the rotor shaft in the radial and not in the axial direction due to its design. Thanks to the use of highly precise and reliable sintered sleeve bearings, it was possible to intelligently solve the problem of the considerable increase in the operating temperature. A special feature of this bearing technology is not only the treatment with thermally stable lubricants but also the magnetic pull that enables smooth running in all installation positions. An additional feature of the fans is the extraordinary high life expectancy of 210.000 h (MTBF). Many of the extremely robust and durable high-temperature fans are available as standard models, however they can be adapted accordingly to meet the individually required parameters (size, tacho output, PWM input, input voltage, connector assembly).

20.03.2018 - High-performance fans for LED cooling – effective customized cooling solutions by SEPA EUROPE

LED lighting provides what today’s customer wants because it is not only energy-efficient but also environmentally friendly and long lasting. However, light-emitting diodes convert a large part of the absorbed power into heat that requires dissipating so that heat management becomes indispensable.

Passive cooling solutions soon reach their limits due to lack of space. Active cooling concepts provide an ideal solution as they are smaller, lighter, enable the required service life and furthermore they are affordable. With its smart compact fans, SEPA EUROPE can provide you with the ideal cooling solution for your LED application.

The round axial fan LF40B12 in combination with a heat sink (Fischer Elektronik) is an example for intelligent heat management made by SEPA EUROPE. It is employed primarily for LED cooling and achieves a remarkable airflow performance despite its compact dimensions. Thanks to the virtually linear fan curve and the extremely low current consumption, the fan is suitable for various applications. It is permanently protected against reverse polarity, blocking and thermal overload. The extremely light-weight rotor is resistant to shock and vibration.

Further features of the LF40B12 fan are its sturdy and dimensionally stable housing of glass-fibre reinforced PBT and the optimised design. The Magfix bearing is renowned for its low noise level and absolute reliability.
