Abstract

A device for guiding air for an air conditioning system of a motor vehicle. The air conditioning system includes air outlets. The device is designed so that it encloses a volume and within the volume at least one air channel extending continuously from an inlet to an outlet is formed. The device is arranged in such a way that can be shifted in a continuously variable manner in a direction between two end positions, wherein the device in the end positions in each case closes an air outlet.
The device may be arranged in an air conditioning system for a motor vehicle with means for conveying, for cooling and for heating an air mass flow, including a housing with a mixing chamber, in which the device for guiding air is arranged.

First claim

What is claimed is:

1. A device for guiding air for an air conditioning system of a motor vehicle, the air conditioning system including a first air outlet and a second air outlet arranged near the device, the device comprising: a first air channel formed within a volume enclosed by the device, the first air channel extending continuously from a first inlet of the volume to a first outlet of the volume, the device continuously slidable along a curvilinear direction between a first end position closing the first air outlet and a second end position closing the second air outlet; and a second air channel arranged separately from the first air channel within the volume, the second air channel extending continuously from a second inlet of the volume to a second outlet of the volume, wherein the air flows both through the first air channel and around a first end of the device to the first air outlet, and through the second air channel and around a second end of the device to the second air outlet, when the device is slidably positioned intermediate to the first and second end positions, wherein the device includes an upper side and a lower side spaced apart from each other in a vertical direction y, wherein the first air channel extends from the upper side of the device to the lower side of the device, and wherein the first inlet is formed on the upper side of the device and the first outlet is formed on the lower side of the device.

2. The device according to claim 1 , wherein the device includes an air guide protruding from the upper side of the device near the first inlet.

3. The device according to claim 2 , wherein the air guide has a width equal to a width of the first inlet.

4. The device according to claim 1 , wherein the first inlet and the first outlet of the first air channel are arranged offset from one another along a horizontal direction x arranged perpendicular to the vertical direction y.

5. The device according to claim 4 , wherein the first inlet and the first outlet are oriented to direct the air in the vertical direction y and the first air channel extends in the horizontal direction x.

6. The device according to claim 1 , wherein the device includes a front side and a back side spaced apart from each other in a horizontal direction x, wherein the second air channel extends from the front side of the device to the back side of the device.

7. The device according to claim 6 , wherein the second inlet is formed on the front side and the second outlet is formed on the back side.

8. The device according to claim 7 , wherein the device includes an air guide protruding therefrom at a transition from the front side to the upper side, the air guide extending along an entirety of a depth of the device measured in a direction z extending perpendicular to each of the vertical direction y and the horizontal direction x.

9. The device according to claim 1 , wherein the device is adjustable along a first direction toward an inlet channel arranged with a static structure, wherein the first air channel of the device at least partially overlaps the inlet channel therein.

10. An air conditioning system for a motor vehicle, comprising: a housing including a first flow path having a first air mass flow having a first temperature directed therethrough, a second flow path having a second air mass flow having a second temperature directed therethrough, a first air outlet, a second air outlet, and a mixing chamber, the first flow path and the second flow path each leading to the mixing chamber, the first air outlet and the second air outlet disposed downstream of the mixing chamber; a device guiding air within the mixing chamber of the housing, the device including a first air channel and a second air channel, the first air channel formed within a volume enclosed by the device, the first air channel extending continuously from a first inlet of the volume located on an upper side of the device, to a first outlet of the volume located on a lower side of the device, the second air channel extending continuously from a second inlet of the volume to a second outlet of the volume, wherein the upper side is spaced apart from the lower side in a vertical direction y, and the device is continuously slidable along a curvilinear direction within the mixing chamber between a first end position closing the first air outlet and a second end position closing the second air outlet, wherein the air flows both through the first air channel and around a first end of the device to the first air outlet, and through the second air channel and around a second end of the device to the second air outlet, when the device is slidably positioned intermediate to the first and second end positions.

11. The air conditioning system according to claim 10 , wherein the first air channel and the second air channel are arranged separately from one another within the volume, and the second inlet formed in a front side of the device and the second outlet formed in a back side of the device, and the front side is spaced apart from the back side in a horizontal direction x arranged perpendicular to the vertical direction y.

12. The air conditioning system according to claim 11 , wherein the device includes a first air guide and a second air guide, the first air guide protruding from the upper side of the device near the first inlet, the second air guide protruding from the device at a transition from the front side to the upper side and extending along an entirety of a depth of the device measured along a direction z extending perpendicular to each of the vertical direction y and the horizontal direction x.

13. The air conditioning system according to claim 12 , wherein the first air guide has a width equal to a width of the first inlet.

14. The air conditioning system according to claim 10 , wherein the device is adjustable along the first direction toward an inlet channel arranged with a static structure, wherein the first air channel of the device at least partially overlaps the inlet channel therein.

15. The air conditioning system according to claim 10 , wherein a temperature flap is disposed downstream of an evaporator in a direction of flow of an entire air mass flow passing through the evaporator, the temperature flap controlling a first portion of the entire air mass flow entering the first flow path as the first air mass flow and a second portion of the entire air mass flow entering the second flow path as the second air mass flow.

16. The air conditioning system according to claim 15 , wherein the second flow path includes a heating heat exchanger of the air conditioning system for heating the second air mass flow.
