Chip cooling with the aid of heat sinks usually requires a lot of space and is not only heavy but also expensive. The specialists at SEPA EUROPE have developed a chip cooler with minimum space requirements for compact designs. The core component of the compact cooler is the ultra-flat blower HY40H that is combined with a Kühligel® of pure aluminium. The special feature of the new cooling solution is its variability which means that the size and shape of the heat sink can be freely chosen. Users can thus assemble the cooler to optimally fulfil their requirements. With a thermal resistance of a mere 2.5 K/W, the new chip cooler withstands a power dissipation of up to 15 W and in doing so guarantees the operational safety of the entire embedded system. The blower is equipped with the highly durable Magfix® sleeve bearing and has an impressive service life expectancy of von 210 000 h (MTBF) at 40 °C.

The significance of air quality measurements whether in industry, households or in vehicles is constantly increasing. Manufacturers therefore, should equip their applications with the optimal sensor fan and in this respect SEPA EUROPE is exactly the right partner! SEPA EUROPE has complemented its range of microfans with the radial fan HY20A with the dimensions of 20 x 20 x 6.3 mm. The air intake of the radial fan which is on one side is 2 l/min and with a sound pressure level of 5dB(A) at a distance of 1m, it is virtually inaudible. As is the case with all microfans, the HY20A is equipped with the reliable Magfix sleeve bearing and has a service life of 400 000 h (MTBF) or 50 000 h (L10) at 40°C. The tachometer output constantly monitors the speed at which the fan is running. The HY20A is also an interesting solution for the cooling of hot spots in embedded applications. This compact blower ensures that optimal use is made of limited installation space.

One of the most popular SEPA EUROPE fans is the axial fan with the dimensions 40x40x10 mm and the popular Magfix® sleeve bearing. This year it underwent complete revision and further development. The new fan generation is known as the LF40P and with the same external dimensions is installed in the same way as the previous model. The new and currently unique rotor geometry is obvious at first sight. It is completely different from the previous shape and layout. Thanks to the distinctive rotor blade with a cut, either a clear noise reduction can be achieved at the same speed or the same noise level as previous generations with 25% more air performance. The current model is equipped with the SEPA MagFix® bearing and PWM input with which the speed can be set to meet the necessary requirements. The LF40P is an excellent example for the permanent further development of products at SEPA EUROPE.

The new super flat active chip cooler of the cooling specialist SEPA EUROPE is a convincing solution for applications in the embedded computing sector, in particular for single board computers. The HZ25B05 with its dimensions of 25x25x6.5 mm can be installed even in flat applications and ensures highly effective heat dissipation. The size of this super flat design is not its only advantage, but also its exceptionally low noise level. The heat sink is made of high-purity aluminium and has low thermal resistance. The integrated micro fan is also equipped with a special, highly durable MagFix® sleeve bearing designed for operating temperatures of up to 80°C. Particularly noteworthy is the fact that the micro fan which is operated with a voltage of 5VDC, has a power input of only 0.3 W and a life expectancy of 400000 hours. The fan can also be equipped, if necessary, with a tacho output for monitoring the function. Both and the fan and the heat sink are available separately.

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.

The fan and cooling specialist SEPA EUROPE has now added three further models to its slimline radial fan series. The latest additions impress with their compact dimensions of 38 x 40 x 5 mm, 54 x 52 x 6 mm and 45 x 45 x 4 mm and have more than deserved the name „slimline“. All fans are equipped with the reliable Magfix sleeve bearings and have a service life of 210 000 h (MTBF) and 40 000 h /L10) at 40 °C. The PWM input in combination with the tacho output enables the speed to be controlled and monitored. It is not obvious at first glance, but the Model HY45AB05PNK00A tops with a pressure of 143 Pa. The new models will be included in the standard range and will therefore be available shortly from stock. SEPA EUROPE specializes in customized cooling solutions. Thanks to over 25 years of experience, SEPA EUROPE can offer you the appropriate solution for virtually every task.

As the need for fans that are used in applications subject to high temperatures is constantly on the increase, SEPA EUROPE 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.

By mounting an axial fan, the effectiveness of the new Kühligel® can be increased considerably. Fanless solutions require a lot of space. They are heavy and expensive. For cooling with active coolers by SEPA EUROPE however, the new Kühligels are not only small and light but also extremely inexpensive. Thanks to intensive development work, SEPA EUROPE was able to construct a heat sink that enables fan mounting without extensive reworking using conventional screws. The choice of the suitable fan (size, sleeve or ball bearings, 5, 12, or 24 VDC, tacho, connector) enables the best possible combination that is required for the application in question. The fans used have a MTBF of up to 350000h (40°C) and thus meet the highest requirements. Thanks to its light weight, the Kühligel® can usually be mounted using double-sided adhesive heat conduction pads (TCTxx) or thermally conductive two-component adhesive (Hernon 746) which are both available from the SEPA EUROPE product range.

Thanks to the intelligent combination of DC fans with a fully integrated AC/DC converter, AC fans can now be operated at speeds that are independent of the power frequency. Up to 4500 rpm can be realized and the flow rate significantly increased if required. The EC generation in the dimensions 80mm to 280mm and with several different speeds replaces the previous AC fans in situtations where there is no DC voltage available and requires less power in the process. The previous AC fans can be replaced without restriction as the EC fans have identical dimensions and thickness. The versions that are smaller than 180mm have a wide-range input and can be connected without problem, worldwide to all AC voltage networks without need for further adaptation. This is underlined by the UL approval of the entire fan series.

The fan and cooling specialist SEPA EUROPE unveils a true innovation this year: The RaAxial fan. This created term is a combination of the words radial and axial. The microfan with its dimensions of 17x17x4.5mm is ideal for compact, embedded applications and offers numerous possibilities, e.g. as an axial fan for the ventilation of housings or as a radial fan for blowing air onto the heat sink. A tailor-made „Kühligel®“ has already been developed for the latter which makes the cooling of hotspots child’s play when space is limited. Reliability has top priority at SEPA EUROPE. For this very reason the new fan is equipped with the tried and tested Magfix® bearing system. The life expectancy at 40 °C is 210 000 h (MTBF) or 40 000 h (L10).

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.

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.

With the purge air method, heat recovery for balanced air mass flows can be determined for alternating, decentralised ventilation units. The uncertainties of the direct measuring method used so far due to inhomogeneous velocity and temperature profiles at the outlet of the ventilation units are circumvented by the scavenging air method and the measuring accuracy is higher. With the optional humidity conditioning the moisture recovery can also be determined. Further thermal performance indicators are the air volume flow in alternating operation and the balance, which can also be determined with the test bench. The test stand is equipped with an auxiliary fan so that continuously operating ventilation units can also be measured with the direct measuring method.
