Abstract

An air guide housing, in particular for a ventilation, heating or air conditioning system of a vehicle, with at least one first air inlet opening, wherein the at least one first air inlet opening has a cross sectional area which is arranged substantially vertical to a first axis, and with at least one second air inlet opening, wherein the at least one second air inlet opening has a cross sectional area which is arranged substantially vertical to a second axis, and having at least one air outlet opening, wherein the at least one air outlet opening has a cross sectional area which is arranged essentially vertical to a third axis, and with a fan impeller for suctioning air into the air guide housing. The second axis and the third axis are arranged substantially parallel to one another.

First claim

What is claimed is:

1. An air guide housing for a ventilation, heating or air conditioning system of a vehicle, the air guide housing comprising:
at least one first air inlet opening having a cross sectional area which is disposed substantially vertical to a first axis;
at least one second air inlet opening having a cross sectional area which is arranged substantially vertical to a second axis;
at least one air outlet opening having a cross sectional area which is arranged essentially vertical to a third axis; and
a fan impeller for suctioning air into the air guide housing, the fan impeller disposed in a center of the air guide housing such that the at least one first air inlet opening is located in a direction of rotation of the fan impeller upstream of the at least one second air inlet opening and the at least one second air inlet opening is located in the direction of rotation of the fan impeller upstream of the at least one air outlet opening, and
wherein the second axis and the third axis are arranged substantially parallel to each other.

2. The air guide housing according to claim 1 , wherein the first axis and the second axis are arranged to each other at an angle of about 90°, and wherein the first axis and the third axis are arranged to one another at an angle of about 90°.

3. The air guide housing according to claim 1 , wherein the at least one first air inlet opening is fluidly connected to a fresh air channel, wherein fresh air from the surroundings of the vehicle is suctioned via the fresh air channel through the at least one first air inlet opening into the air guide housing.

4. The air guide housing according to claim 1 , wherein, through the at least one second air inlet opening, circulating air is suctioned from an air circulating duct and/or from a cabin of the vehicle into the air guide housing.

5. The air guide housing according to claim 1 , wherein the fan impeller is rotatably mounted about a fourth axis, wherein the second axis and the fourth axis are arranged to each other substantially at an angle of about 90°.

6. The air guide housing according to claim 5 , wherein the first axis and the fourth axis are arranged substantially parallel to each other, and wherein the third axis and the fourth axis are arranged to each other at an angle of about 90°.

7. The air guide housing according to claim 1 , wherein an air filter is arranged in an air flow direction downstream of the at least one air outlet opening.

8. The air guide housing according to claim 1 , wherein, in the region of the at least one first air inlet opening and/or in the region of the at least one second air inlet opening and/or in the region of the at least one air outlet opening, connecting elements for connecting the air guide housing are formed with a fluid channel array.

9. The air guide housing according to claim 1 , wherein, in the region of the air guide housing and/or in a region adjacent to the air guide housing, at least one air flow control device and/or at least one air flow control assembly for selective and/or partially metered suctioning and/or ventilation of the air guide housing with fresh air and/or circulating air is arranged.

10. A ventilation, heating or air conditioning system, wherein the ventilation, heating or air conditioning system comprises at least one air guide housing according to claim 1 .

11. An air guide housing, comprising:
a first air inlet;
a second air inlet disposed perpendicular to the first air inlet;
an air outlet disposed parallel to the second air inlet and perpendicular to the first air inlet; and
a fan impeller for suctioning air into the air guide housing through the first air inlet and the second air inlet, the fan impeller disposed in a center of the air guide housing such that the first air inlet is located in a direction of rotation of the fan impeller upstream of the second air inlet and the second air inlet opening is located in the direction of rotation of the fan impeller upstream of the air outlet,
wherein an angle between the third axis and the second axis is approximately 180°.

12. The air guide housing according to claim 11 , wherein the first air inlet has a cross sectional area that is disposed vertical to a first axis, the second air inlet has a cross sectional area that is arranged vertical to a second axis and the air outlet has a cross sectional area arranged vertical to a third axis.

13. An air guide housing, comprising:
a first air inlet;
a second air inlet disposed perpendicular to the first air inlet;
an air outlet disposed parallel to the second air inlet and perpendicular to the first air inlet; and
a fan impeller for suctioning air into the air guide housing through the first air inlet and the second air inlet, the fan impeller disposed in a center of the air guide housing such that the first air inlet is located in a direction of rotation of the fan impeller upstream of the second air inlet and the second air inlet is located in the direction of rotation of the fan impeller upstream of the air outlet.
