About ZIEHL-ABEGG

上海菁园科技有限公司

Ziehl-Abegg (Kuenzelsau, Baden-Wurttemberg, Germany) is one of the leading global companies in the field of ventilation, control and drive technology. Back in the Fifties, Ziehl-Abegg established the basis for modern fan drives: external rotor motors which even today are still seen as state-of-the-art worldwide. Another area of business is electric motors which provide the power, for example, for elevators, medical applications (computer tomography equipment) or deep-sea underwater vehicles. The theme of electro-mobility for motor vehicles was established as part of the Ziehl-Abegg Automotive Team in 2012. 

The high-tech company has an impressive innovative capability. Ziehl-Abegg employs 2,000 personnel in its production plants in Southern Germany. The company has a global workforce of 3,550 spread between 16 production plants, 27 companies and 97 sales locations. The products, approx. 30,000 in all, are sold in more than 100 countries. Turnover in 2016 totalled 484 million euros, with exports accounting for three quarters of the figure.

Emil Ziehl founded the company in Berlin in 1910 as a manufacturer of electric motors. After the Second World War the company’s headquarters were relocated to Southern Germany. Ziehl-Abegg SE is not a listed company but instead is family-owned

早在五十年代,Ziehl-Abegg建立现代风扇驱动的基础:外转子电机,即使在今天仍被视为全球的。另一个领域的业务是电动马达提供动力,例如,电梯,医疗应用程序(计算机断层摄影设备)或深海潜水器。电动车产业的主题建立了机动车辆在2012年作为Ziehl-Abegg汽车团队的一部分。高科技公司拥有一个令人印象深刻的创新能力。Ziehl-Abegg雇佣了2000名人员在德国南部生产工厂。该公司全球员工总数3550差16个生产工厂,97年公司和27日销售位置。产品,大约。30000年,在100多个国家销售。2016年营业额高达4.84亿欧元,出口占四分之三的图。埃米尔Ziehl创立公司于1910年在柏林作为电动汽车的制造商。二战后公司总部迁至德国南部。Ziehl-Abegg本身不是一个上市公司,而是家族

 

Ziehl-Abegg showcased ZAbluefin for central air-conditioning control units at ISH in Frankfurt

 

Once again, Ziehl-Abegg put the spotlight on bionics for many of the visitors at the ISH trade fair in Frankfurt. This time a marine mammal was the idea behind a new fan development. So, a small cinema on the subject of "whale watching" was integrated into the large trade fair stand which was opened by a speech from the whale researcher Dr. Karsten Brensing, with give-aways in the form of a man-sized inflatable whale for the summer holidays.

 

“The trade fair stand was repeatedly inundated with visitors” to the delight of Peter Fenkl, Chairman of the Board of Ziehl-Abegg. The main focus of interest was on the innovative fan ZAbluefin which increases efficiency by up to 15 percent. "That’s why our engineers have clearly underlined their position at the forefront of bionics and as leaders in fan technology" emphasises Fenkl.”

 

The development engineers studied the physical structure and characteristics of the humpback whale in order to transfer elements to the new radial impeller ZAbluefin. It’s also the reason why the marine biologist Dr. Karsten Brensing spoke at the opening of Ziehl-Abegg’s presence at the trade fair. The acknowledged expert on whales explained to visitors how the 30-ton marine mammals live and hunt - and in this context are dependent on being extremely agile. Evolution has optimised the animal’s body for movement through the water so they are also capable of undertaking journeys covering several thousand kilometres with a minimal expenditure of energy.

 

CEO Fenkl explained which elements of the humpback whale are replicated in the radial impeller ZAbluefin: for example, the leading edge of the fan blade has an undulating profile – this is modelled on the golf-ball sized bumps (technical term: tubercle) on the whale’s fins。 This avoids excessive turbulence, reducing both flow losses and noise。 The flow engineers have also taken a close look at the whale’s rear fin, the “fluke”。 The v-shaped contour of the rear section of the wing delays potential flow breaks – enabling the fan to be used for numerous different pressure ranges。 The latest generation of radial fans at Ziehl-Abegg in sizes from 710 mm, is now benefitting from this knowledge which has been gained in the field of bionics。 The product name ZAbluefin comes from the English。

 

The experts at Ziehl-Abegg spent about two years on the new radial impeller for central air conditioning control units and industrial ventilation. A bionic profile has proven very effective in terms of efficiency and low-noise. Unlike hollow blades which are currently commercially available, the bionic profile blades have no gaps that allow dirt or condensation to penetrate and which would not only lead to corrosion but also create an imbalance. The steel is therefore compressed into a corrugated shape using a 600-ton press, creating the bionic profile, giving additional strength and reducing weight. “And a more lightweight design protects the bearings in the motor” adds Fenkl.

 

四川11选5走势图The new radial impeller not only possesses bionic features of the whale. It also incorporates bionic elements of the owl. For example, the trailing edges of the ventilator blades recreate the flight of an owl. “As the quietest bird of prey, we have already used the owl as a model for a number of designs” says Fenkl. Serrated trailing edges on fans have since become one of Ziehl-Abegg’s trademarks.  On the new fan however the edges have been modified and softened. So, the innovative fan combines knowledge gained from aerodynamics (ornithology) as well as hydrodynamics (marine biology).上海菁园科技有限公司!
