A charge air duct for an internal combustion engine includes a housing with at least one entrance and at least one exit for charge air, a first heat exchanger arranged inside the housing to cool the charge air, a bypass arranged on the housing to at least partially circumvent the heat exchanger, and
A charge air duct for an internal combustion engine includes a housing with at least one entrance and at least one exit for charge air, a first heat exchanger arranged inside the housing to cool the charge air, a bypass arranged on the housing to at least partially circumvent the heat exchanger, and an actuator arranged on the housing to influence the charge air flow. The charge air is guided from the entrance to the first heat exchanger in a first position of the actuator and from the entrance to the bypass in a second position of the actuator, and the bypass leads upstream of a second heat exchanger of the charge air duct.

1. A charge air duct for an internal combustion engine, comprising: a housing having at least one inlet and at least one outlet for charge air,wherein a first heat exchanger is disposed in the housing to cool the charge air,wherein a bypass is disposed on the housing to at least partially circumvent the first heat exchanger,wherein an actuator is disposed on the housing to influence the charge air flow,wherein the charge air is guided from the inlet to the first heat exchanger in a first position of the actuator,wherein the charge air is guided from the inlet to the bypass in a second position of the actuator,wherein the bypass leads upstream of a second heat exchanger of the charge air duct, andwherein a second bypass is provided, the second bypass leading from upstream of the first heat exchanger to downstream of the second heat exchanger, to thereby circumvent the first and second heat exchangers. 2. The charge air duct according to claim 1, wherein the first heat exchanger is in the form of a high temperature heat exchanger, and the second heat exchanger is in the form of a low temperature heat exchanger. 3. The charge air duct according to claim 1, wherein the charge air flows from the inlet to the second bypass in a third position of the actuator. 4. The charge air duct according to claim 1, wherein the charge air duct is in the form of an intake manifold of the internal combustion engine. 5. The charge air duct according to claim 1, wherein the actuator is disposed in a duct which is substantially cylindrical, wherein the charge air flow is redirected by approximately 90° in the region of the duct. 6. The charge air duct according to claim 1, wherein the actuator is in the form of a roller which is rotatable about an axis. 7. The charge air duct according to claim 1, wherein the actuator comprises a blocking surface, and wherein the blocking surface has a geometric structure to reduce the flow cross-section. 8. The charge air duct according to claim 1, wherein the housing can be attached to the internal combustion engine via two parallel rows of screw connections, wherein, at least one of the screw connections extends through a part of the housing. 9. The charge air duct according to claim 8, wherein at least one of the heat exchangers is disposed between the parallel rows of screw connections. 10. The charge air duct according to claim 1, wherein the charge air flow is redirected, in particular by 180°, after the heat exchanger of the two that is upstream, and before the heat exchanger of the two that is downstream. 11. The charge air duct according to claim 1, wherein the actuator is disposed substantially in a plane with the two heat exchangers and also in a plane with the outlet of the charge air duct. 12. The charge air duct according to claim 1, wherein the two heat exchangers and the outlet are disposed substantially in a plane, and wherein the actuator is disposed outside of this plane entirely above or entirely below the plane. 13. The charge air duct according to claim 1, wherein a throttle element is provided in addition to the actuator. 14. The charge air duct according to claim 1, wherein the entire actuator is located upstream of the first heat exchanger.
