Abstract

The invention discloses a cooling device for a vehicle. The cooling device may include a heat exchanger provided to cool an engine of the vehicle, a radiator provided near a side of and in parallel with the heat exchanger to cool an inside of the vehicle, and a cooling fan provided near a side of the radiator to coercively introduce external air into the heat exchanger and the radiator, wherein the cooling fan includes a hub connected to a driving shaft, and a plurality of blades radially arranged on an outer circumferential surface of the hub, wherein the plurality of blades are arranged so that a spaced area between two neighboring blades is different from a spaced area between other two neighboring blades, and wherein a sum of all vectors for the plurality of blades is not zero, the vector being reached from the center of the hub to a reference point of each blade.

Description

[0001] This formal application claims priority from Korean Patent Application No. 10-2009-0059301 filed on Jun. 30, 2009, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention is directed to the field of cooling vehicles, and more particularly, the present invention is directed to a cooling device for a vehicle having a cooling fan that forcibly introduces external air into a cooling system provided in the vehicle for convective heat exchange. heat exchangers and radiators. Background technique [0003] Generally, in order to cause convective heat transfer, a vehicle includes a cooling fan that forcibly introduces outside air into a heat exchanger provided for cooling an engine accommodated in an engine compartment, and a radiator. A radiator is provided for cooling the interior of the vehicle. [0004] The cooling fan includes a hub connected to a drive shaft, and a plurality of blades provided on an outer circumf...
