1. A fan module for cooling motor vehicle engines, comprising: a fan housing,a fan motor disposed in the fan housing,a fan wheel driven by the fan motor, wherein the fan housing has fixed air guiding elements which are arranged in the area of a fan hub of the fan wheel and only partially cover an outlet cross-section defined by the fan housing,fan blades arranged at the fan hub, with a number of fan blades in the area of the fan hub having a fan blade section, which fan blade section is embodied in the manner of a fixed split flap, wherein the fan blade section has the flow opening arranged in the area of the trailing edge of the fan blade. 2. The fan module according to claim 1, wherein the air guiding elements cover an area of 10 to 50 percent of the outlet cross-section. 3. The fan module according to claim 1, wherein air guiding elements are arranged at an angle of attack α relative to the flow direction of the cooling air and that the angular position of the air guiding elements is dependent on the radius of the fan wheel. 4. The fan module according to claim 3, wherein the angle of attack α of the air guiding elements is between α=12° for r=d and α=45° for r=1.3×d, where “r” denotes the radius of the fan wheel and “d” the diameter of the fan hub. 5. The fan module according to claim 1, wherein the outer ends of the air guiding elements are connected to one another by way of an outer race. 6. The fan module according to claim 1, wherein the radial length of the flow opening corresponds to a maximum of 30 percent of the hub radius. 7. The fan module according to claim 1, wherein the width of the flow opening is between 35 and 45 percent of the fan blade width. 8. The fan module according to claim 1, wherein the angle of attack of the fan blade section is 40 to 55 degrees greater than the angle of attack of the fan blade 2. 9. The fan module according to claim 1, wherein the radial length of the flow opening is dimensioned in such a way that the flow opening terminates with the outer race of the air guiding elements. 10. A fan module comprising a fan housing, a fan motor disposed in the fan housing, and a fan wheel driven by the fan motor, wherein the fan housing has fixed air guiding elements which are arranged in the area of a fan hub of the fan wheel and only partially cover an outlet cross-section defined by the fan housing, wherein fan blades are arranged at the fan hub, with a number of fan blades in the area of the fan hub having a fan blade section for the purpose of forming a flow opening, which fan blade section is embodied in the manner of a fixed split flap for the purpose of generating an increased static air pressure close to the fan hub, wherein the fan blade section has the flow opening arranged in the area of the trailing edge of the fan blade. 11. The fan module according to claim 10, wherein the air guiding elements cover an area of 10 to 50 percent of the outlet cross-section. 12. The fan module according to claim 10, wherein air guiding elements are arranged at an angle of attack α relative to the flow direction of the cooling air and that the angular position of the air guiding elements is dependent on the radius of the fan wheel. 13. The fan module according to claim 12, wherein the angle of attack α of the air guiding elements is between α=12° for r=d and α=45° for r=1.3×d, where “r” denotes the radius of the fan wheel and “d” the diameter of the fan hub. 14. The fan module according to claim 10, wherein the outer ends of the air guiding elements are connected to one another by way of an outer race. 15. The fan module according to claim 10, wherein the radial length of the flow opening corresponds to a maximum of 30 percent of the hub radius. 16. The fan module according to claim 10, wherein the width of the flow opening is between 35 and 45 percent of the fan blade width. 17. The fan module according to claim 10, wherein the angle of attack of the fan blade section is 40 to 55 degrees greater than the angle of attack of the fan blade. 18. The fan module according to claim 10, wherein the radial length of the flow opening is dimensioned in such a way that the flow opening terminates with the outer race of the air guiding elements.
