The invention relates to a ram air duct for an aeroplane air conditioning system having an inlet channel which can be closed by an inlet valve and in which at least one heat exchanger is arranged, having a blower arranged in a blower chamber and an outlet passage closable by an outlet valve. In accordance with the invention, the outlet passage is divided into two separately extending passages of which one is guided as a blower outlet passage up to the blower into the blower chamber and the other is designed as a bypass passage. The outlet valve only closes the bypass passage in the closed state.

1. A ram air duct for an aeroplane air conditioning system having an inlet channel, an inlet valve structured and arranged to close the inlet channel, and at least one heat exchanger arranged in said duct, said heat exchanger having a blower chamber, a blower arranged in the chamber,
1. A ram air duct for an aeroplane air conditioning system having an inlet channel, an inlet valve structured and arranged to close the inlet channel, and at least one heat exchanger arranged in said duct, said heat exchanger having a blower chamber, a blower arranged in the chamber, an outlet passage, and an outlet valve structured and arranged to close the outlet passage, wherein the outlet passage is divided into two separately extending passages, one of said outlet passages being guided as a blower outlet passage up to the blower and into the blower chamber, and the other of said outlet passages being structured and arranged as a bypass passage to direct flow therethrough bypassing said blower and blower chamber, and the outlet valve is structured and arranged to only close the bypass passage and not the blower outlet passage. 2. A ram air duct in accordance with claim 1, wherein the blower outlet passage has a guide vane grid in its outlet.3. A ram air duct in accordance with claim 2, wherein the impeller is structured and arranged to direct fluid flow therethrough in a direction of its drive.4. A ram air duct in accordance with claim 2, wherein the impeller is structured and arranged to direct fluid flow therethrough counter to a direction of its drive.5. A ram air duct in accordance with claim 2, additionally comprising a control apparatus for the separate controlling of the inlet valve or the outlet valve.6. A ram air duct in accordance with claim 2, wherein the blower outlet passage and the bypass passage are disposed next to one another and are separated by a common partition wall.7. A ram air duct in accordance with claim 1, wherein the impeller is structured and arranged to direct fluid flow therethrough in a direction of its drive.8. A ram air duct in accordance with claim 7, additionally comprising a control apparatus for the separate controlling of the inlet valve or the outlet valve.9. A ram air duct in accordance with claim 1, wherein the impeller is structured and arranged to direct fluid flow therethrough counter to a direction of its drive.10. A ram air duct in accordance with claim 1, comprising a control apparatus for the separate controlling of the inlet valve or the outlet valve.11. A ram air duct in accordance with claim 1, wherein the blower outlet passage and the bypass passage are disposed next to one another and are separated by a common partition wall.12. A ram air duct in accordance with claim 1, wherein the blower outlet passage and the bypass passage are guided as separate lines.13. A ram duct in accordance with claim 11, wherein the partition wall extends up to the end of the blower outlet passage and the bypass passage.14. A ram air duct in accordance with claim 11, wherein the partition wall is shorter than the blower outlet passage and the bypass passage.15. A ram air duct in accordance with claim 1, additionally comprising a manifold structured and arranged such that air conveyed by the impeller flows radially into the manifold.16. A ram air duct in accordance with claim 1, wherein the blower outlet passage is structured and arranged to be closed by a separate valve.17. A ram air duct in accordance with claim 1, wherein a jet pump is additionally integrated in the blower outlet passage.18. A ram air duct in accordance with claim 1, comprising a motor as a drive for the impeller and structured and arranged to operate as a generator when the impeller is driven by circulating fluid.19. A ram air duct is accordance with claim 1, additionally comprising at least one turbine to drive the impeller.20. A ram air duct in accordance with claim 19, additionally comprising a compressor blade in the turbine.
