Abstract

The present application discloses a device and method for controlling the rotation speed of a cooling fan, wherein the device for controlling the rotation speed of a cooling fan includes: a cooling fan motor that runs the cooling fan; a pump that is connected in series to the cooling fan motor; a relay, One side of it is connected to the cooling fan motor or the pump, and the other side is connected to the battery, so that the power of the battery can be supplied to either of the cooling fan motor or the pump.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2014-0162535 filed on November 20, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to an apparatus and method for controlling the rotational speed of a cooling fan, and more particularly, to an apparatus and method for controlling the rotational speed of a cooling fan by using a pump. Background technique [0004] The temperature of the internal combustion engine of the vehicle increases as the vehicle runs, and the hot engine is usually cooled by an air cooling method or a water cooling method. The air cooling method allows the engine to be exposed to the atmosphere without additional assistance, which avoids cooling water freezing and leakage, etc. However, when the temperature of the outside air is high or the vehicle is parked temporarily, the cooli...
