12世纪末在西欧出现了*批风车。有些人认为，无锡风力风机制造有限公司在巴勒斯坦参加了十字军东侵的士兵们回家时带回了关于风车的信息。但是，西方风车的设计与叙利亚的风车迥然不同，因而它们可能是独立发明出来的。典型的地中海风车有着圆形石塔和朝向盛行风安装的垂直翼板。它们仍用于磨碎谷物。1862年，英国的圭贝尔发明离心风机，其叶轮、机壳为同心圆型，机壳用砖制，木制叶轮采用后向直叶片，效率仅为40%左右，主要用于矿山通风。1880年，人们设计出用于矿井排送风的蜗形机壳，和后向弯曲叶片的离心风机，结构已比较完善了。892年法国研制成横流风机；1898年，爱尔兰人设计出前向叶片的西罗柯式离心风机，并为各国所广泛采用；19世纪，轴流风机已应用于矿井通风和冶金工业的鼓风，但其压力仅为100～300帕，效率仅为15～25%，直到二十世纪40年代以后才得到较快的发展。 （图/文http://www.wxfengli.com/）

At the end of twelfth Century appeared in Western Europe in the first batch of windmill. Some people think that, in Palestine participated in the crusade of the soldiers home brought about the information. However, the Western windmill design and windmills in Syria be totally different, so they may be independently invented. Typical Mediterranean windmills with round towers and the prevailing wind is mounted for vertical wing plate. They are still used to grind corn. In 1862, Britain's Goebel invention centrifugal fan, the impeller, the casing is concentric circle type, casing with brick, wooden impeller using backward straight blades, efficiency of only about 40%, mainly used for mine ventilation. In 1880, people design for mine exhaust air scroll casing, and backward curved blade centrifugal fan, structure has a relatively perfect. 892 years of French developed into a cross-flow fan;1898, the Irish design prior to the San Siro Ke blade centrifugal fan, and used by the countries widely; nineteenth Century, axial flow fan has been applied to the mine ventilation and metallurgical industrial blast, but the pressure is only 100 ~300 kPa, efficiency is only 15~ 25%, until twentieth Century40 time later to get rapidder development.
