摘要： The invention relates to a fan (1), comprising: a central hub (2); a plurality of blades (3) connected to this hub (2) and extending at least more or less in radial direction, which blades (3) take a form such that when driven rotatably round the axis of the hub (2) an air displacement occurs; and drive means (7, 8, 9) for rotatably driving the blades with the hub round the axis of the hub. The invention provides a fan of the stated type which has the feature that the end zones (4) of the blades are connected by a ring (5), which ring (5) is supported rotatably in a housing; and the drive means comprise a motor (7) which is placed at a distance from the hub outside the air flow generated by the driven blades (3).
摘要翻译：本发明涉及一种风扇（1），包括：中心毂（2）; （2）连接并且至少在径向方向上延伸的多个叶片（3），所述叶片（3）采取这样的形式，使得当围绕轮毂（2）的轴线可旋转地围绕时，空气排出量发生; 以及驱动装置（7,8,9），用于以所述轮毂围绕所述轮毂的轴线旋转驱动所述叶片。本发明提供一种所述类型的风扇，其特征在于，叶片的端部区域（4）通过环（5）连接，该环（5）可旋转地支撑在壳体中; 并且驱动装置包括马达（7），马达（7）被放置在由从动叶片（3）产生的气流外侧距离轮毂一定距离处。

摘要： A combination of a fan (2), a heat exchanger (3) and a housing (4); which fan (2) comprises: a central hub (5); a plurality of blades (6) connected to this hub (5) and extending at least more or less in radial direction, which blades take a form such that when driven rotatably round the axis of the hub an air displacement occurs; drive means (10) for rotatably driving the blades with the hub round the axis of the hub, which heat exchanger (3) comprises: a plurality of hollow panels (13) placed at a mutual distance, for instance substantially parallel to each other, in one spiral form or substantially coaxially, through which panels (13) medium can flow, and which have a medium inlet (31) and a medium outlet (32); which housing (4) comprises: a casing (16) with a tubular passage in which the fan (2) and the heat exchanger (4) are placed such that air flow generated by the fan (2) flows through the spaces between the hollow plates for heat exchanging contact via the walls of these plates between the air in the air flow and the medium flowing through the hollow plates.
