## Abstract

A crossmember (20) for a front bumper of a motor vehicle (10) has at least one throughflow opening for air. At least one exit-air opening (51, 52) is provided on a rear side (44) of the crossmember (20) to accommodate a discharge of exit air from a cooler of the motor vehicle.

## Claims

### Claim 1

A crossmember for a front bumper of a motor vehicle, the motor vehicle including a cooler arranged at least partly below the crossmember, the crossmember comprising:
a crossmember main body extending in a direction transverse to a longitudinal direction of the motor vehicle, the crossmember main body having opposite first and second ends with exit-air outlet openings and a cavity extending between the exit-air outlet openings, a rear side with at least one exit-air inlet opening formed in the rear side at a position centrally located between the first and second ends, and a dividing body disposed in the cavity and extending at least partially between the first and second ends in the direction transverse to the longitudinal direction, and closed top, bottom, and front sides;
and
an exit-air guiding device arranged behind the cooler and configured to collect exit-air emerging from the cooler and to direct at least a portion of the exit-air to the exit-air inlet opening for delivery of the exit-air to the exit-air outlet openings of the crossmember.

### Claim 2 (depends on 1)

The crossmember of claim 1, further comprising exit-air ducts extending laterally from the exit-air guiding device below the crossmember.

### Claim 3 (depends on 2)

The crossmember of claim 2, wherein the exit-air ducts extend toward wheel arches.

### Claim 4 (depends on 1)

The crossmember of claim 1, wherein the exit-air outlet openings extend toward wheel wells.

### Claim 5 (depends on 1)

A motor vehicle comprising the crossmember of claim 1.

### Claim 6

A front end of a motor vehicle, comprising:
a crossmember for supporting a front bumper of the motor vehicle, the crossmember including a crossmember main body extending in a direction transverse to a longitudinal direction of the motor vehicle, the crossmember main body having opposite first and second ends with exit-air outlet openings and a cavity extending between the exit-air outlet openings, and a rear side with at least one exit-air inlet opening formed therein, and a dividing body disposed in the cavity and extending at least partially between the first and second ends in the direction transverse to the longitudinal direction;
a cooler arranged at least partly below the crossmember; and
an exit-air guiding device arranged behind the cooler and configured to collect exit-air emerging from the cooler and to direct at least a portion of the exit-air to the exit-air inlet opening for delivery of the exit-air to the exit-air outlet openings of the crossmember.
