The chip cooler of the HXB series by SEPA EUROPE is a compact combination of fan and heat sink and is an attractively priced combination with an adequate cooling capacity. But the development engineers at SEPA EUROPE wanted to go further and this pushing ahead marked the birth of the 3DQler. The cooperation with the experts of APWORKS provided the decisive impulse. Due to the metal 3D printing, also known as additive manufacturing, APWORKS is in the position to produce geometrically highly complex heat sinks. Without having to change the external dimensions or make the fan more powerful, the additively manufactured version can be realized with 30% more efficient waste heat. With the 3DQler, SEPA EUROPE and APWORKS have developed a modern and active cooling concept that offers numerous advantages: Freedom of design with regard to installation space and a reduction of the manufacturing costs.

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 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).

Even the micro fan MF17B05 from the RaAxial range was a true innovation simply because it can be used not only as an axial fan but also as a radial fan. The micro fan has now a „big brother“– the LF40E05. The LF40E05 provides numerous possibilities for embedded applications. It can be used either as an axial fan with integrated finger guard or as a radial fan in combination with a heat sink. Together with a matching Kühligel® the flat cooling units have a height of approx. 12 mm. In other words, they are ideal for compact applications. In order to achieve the optimum size and heat dissipation, customized dimensions and shapes can be realized. The new model with its 0.15 W power input during operation, is extremely economical with regard to its diverse application possibilities. And that’s not all, the new RaAxial fan has aerodynamically optimized blades that have a significant effect on the noise behaviour. The LF40E05 is thus exceptionally quiet.

Based on the axial fan series MFB60B that has been extremely successful for many years on the market, SEPA EUROPE is now presenting a powerful upgrade with its PLB60B series. The fans of the PLB60B series, with the dimensions 60x60x15 mm have an optimized blade geometry that enables a maximum flow rate of 28 m³/h. The new SEPA fans set new standards in their class and are suitable for reliable CPU cooling in a broad range of applications. The robust ball bearing system guarantees a long service life of 70.000 h L10 and 550.000 h MTBF at 40 °C and ensures a safe and smooth operation over many years. The fail-safe axial fans are available in the operating voltages 5, 12 and 24. A PWM input with which the speed can be adjusted according to requirements is an available option.

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.
