Cooling fan for internal combustion engine having axially adjustable fan rotor
Abstract:
A cooling fan (10) for a vehicle engine (50), having a fan casing (60) and a fan rotor (12) which is movable axially relative to the fan casing during operation. There is an actuator (20) for moving the fan rotor (12) to positions which represent various degrees of protrusion (a) from an end of the fan casing (60) in order to optimise the fan's suction capacity and efficiency on the basis of current operating parameters such as fan speed and vehicle velocity.
Abstract(Chinese):

一种用于车辆发动机（50）的冷却风扇（10），具有风扇壳体（60）和风扇转子（12），该风扇壳体在运行期间可相对于风扇壳体轴向运动。 存在用于将风扇转子（12）移动到从风扇壳体（60）的端部表示不同程度的突出（a）的位置的致动器（20），以便基于以下方式优化风扇的吸入能力和效率 目前的运行参数，如风扇转速和车速。
