Abstract
A cooling fan module for a motor vehicle. has a first fan motor which is used to drive a first cooling fan and a second fan motor which is used to drive a second cooling fan. A control unit (6, 13) is associated with the first fan motor (2, 11), which operates the first fan motor (2, 11) and the second fan motor (4, 12, 23) simultaneously, in order to provide an economical and compact technical solution for the cooling fan.
Claims14
A cooling fan module for a motor vehicle, comprising a brushless first fan motor for driving a first cooling fan and a second fan motor for driving a second cooling fan, a control unit being assigned to the first fan motor, which, at the same time as operating the first fan motor, also operates the second fan motor.
A method for operating a cooling fan module for a motor vehicle, wherein the cooling fan module has a brushless first fan motor for driving a first cooling fan and a second fan motor for driving a second cooling fan, the method comprising the steps of:
- assigning a control unit to the first fan motor, which, as well as operating the first fan motor also operates the second fan motor at the same time, and
- controlling the first fan motor via the control unit with speed regulation and the speed of the second fan motor being set as a function of the speed of the first fan motor.
A cooling fan module for a motor vehicle, comprising
- a brushless first fan motor driving a first cooling fan and a second fan motor driving a second cooling fan, a control unit being assigned to the first fan motor, the control unit being operable to set the speed of the second fan motor as a function of the speed of the first fan motor.
