Fan module for a heat exchanger for a transportation vehicle drive

1 . A fan module for a heat exchanger for a drive of a transportation vehicle, the fan module comprising at least the following components:

at least one fan wheel for delivering air in a predetermined delivery direction;

a frame for connection to a heat exchanger and for accommodating the at least one fan wheel; and

positioned in the delivery direction behind at least one of the fan wheel, a guiding device having at least one guide vane for orienting the flow of the air delivered by the particular fan wheel,

wherein at least one of the guiding device imposes, on the flow of the air delivered by the respective fan wheel, an orientation having a first vector component in the cross direction to the delivery direction and a second vector component in the delivery direction,

wherein the first vector component is greater than the second vector component,

wherein the at least one guide vane of the at least one guiding device comprises a first blade section and a second blade section for imposing an orientation on the flow, wherein the first blade section reduces the spin of the flow of the delivered air that is induced by the respective fan wheel,

wherein the at least one guiding device further comprises a guiding element separate from the frame,

wherein the first blade section forms a single piece with the frame and the second blade section forms a single piece with the guiding element, and

wherein the respective orientations imposed on the flow by a plurality of guide vanes are different from each other.

2 . The fan module of claim 1 , wherein the guiding element is fixed by a central mounting of the frame.

3 . The fan module of claim 1 , wherein the delivery direction of the respective fan wheel is opposite a main travel direction of the transportation vehicle.

4 . The fan module of claim 1 , wherein the fan module is configured to be encapsulated with an engine compartment housing at least part of the drive, wherein the configuration of the fan module provides a minimum distance between at least one of the fan wheels of the fan module and a directly adjacent machine unit that is less than 5 cm.

5 . The fan module of claim 4 , wherein the directly adjacent machine unit is a motor or motor unit component.

6 . A transportation vehicle comprising:

a drive for generating a propulsive torque;

an engine compartment for accommodating at least part of the drive;

at least one driving wheel by which the propulsive torque of the drive is transformed into a propulsion of the transportation vehicle;

at least one heat exchanger for temperature control of at least part of the drive; and

at least one fan module for delivering air through the at least one heat exchanger, wherein the at least one fan module including at least one fan wheel for delivering air in a predetermined delivery direction, a frame for connection to the at least one heat exchanger and for accommodating the at least one fan wheel, and positioned in the delivery direction behind at least one of the fan wheel, a guiding device having at least one guide vane for orienting the flow of the air delivered by the particular fan wheel,

wherein at least one of the guiding device imposes, on the flow of the air delivered by the respective fan wheel, an orientation having a first vector component in the cross direction to the delivery direction and a second vector component in the delivery direction,

wherein the first vector component is greater than the second vector component,

wherein the at least one guide vane of the at least one guiding device comprises a first blade section and a second blade section for imposing an orientation on the flow, wherein the first blade section reduces the spin of the flow of the delivered air that is induced by the respective fan wheel,

wherein the at least one guiding device further comprises a guiding element separate from the frame,

wherein the first blade section forms a single piece with the frame and the second blade section forms a single piece with the guiding element, and

wherein the respective orientations imposed on the flow by a plurality of guide vanes are different from each other.

7 . The transportation vehicle of claim 6 , wherein the delivery direction of the at least one fan wheel of the fan module is opposite the main travel direction of the transportation vehicle.

8 . The transportation vehicle of claim 6 , wherein the engine compartment is encapsulated, wherein a minimum distance between at least one of the fan wheels of the fan module and a directly adjacent machine unit is less than 5 cm.

9 . The transportation vehicle of claim 8 , wherein the directly adjacent machine unit is a motor or motor unit components.

10 . The transportation vehicle of claim 6 , wherein the guiding element is fixed by a central mounting of the frame.
