Abstract

The invention relates to an air cooling device ( 1 ) for a vehicle, notably a motor vehicle, comprising:—at least a reserve ( 3 ) of liquid, —a device ( 5 ) for nebulizing the liquid, —at least two air outlets ( 7 ) for diffusing at least an air flow (F 1 , F 2 ) intended for the interior of the said vehicle, and—at least two nebulizing ducts ( 9 ) respectively intended to have passing through them an air flow (F 1 ) laden with droplets of nebulized liquid, each nebulizing duct ( 9 ) being arranged in fluidic communication with the reserve ( 3 ) of liquid and with an associated air outlet ( 7 ). According to the invention, the air cooling device ( 1 ) comprises at least one nebulizing regulating member ( 19 ) to regulate the flow rate of the air flow (F 1 ) laden with droplets of nebulized liquid passing along a nebulizing duct ( 9 ) and to be diffused through the air outlet ( 7 ) associated with this nebulizing duct ( 9 ).

First claim

The invention claimed is:

1. An air cooling device for a motor vehicle, comprising:
at least one liquid reserve;
at least one nebulizing device for nebulizing liquid droplets;
at least two air outlets respectively configured for diffusing at least one air flow for an interior of the motor vehicle, wherein at least one air flow from the at least two air outlets mix with the liquid droplets;
at least two nebulizing pipes traversed by an air flow of the at least one air flow laden with the liquid droplets nebulized by the at least one nebulizing device, each nebulizing pipe being arranged in fluidic communication with the at least one liquid reserve and with a corresponding air outlet of the at least two air outlets; and
at least one nebulizing regulating member configured to regulate a flow rate of the air flow laden with the liquid droplets nebulized by the at least one nebulizing device that traverses one of the at least two nebulizing pipes and to be diffused through the corresponding air outlet of the one of the at least two nebulizing pipes,
wherein the at least one nebulizing regulating member is produced in a form of a distribution flap, and
wherein the distribution flap is arranged at a junction of the at least two nebulizing pipes, so as to move between two end positions for closure of either one of the at least two nebulizing pipes, so as to distribute the air flow laden with the liquid droplets nebulized by the at least one nebulizing device for each of the corresponding air outlets of the at least two nebulizing pipes.

2. The air cooling device as claimed in claim 1 , comprising:
at least two first pipes forming the at least two nebulizing pipes intended to be traversed by a first air flow; and
at least two second pipes respectively traversed by a second air flow distinct from the first air flow; and
wherein each second pipe is associated with a corresponding first pipe of the at least two first pipes and is arranged in fluidic communication with the corresponding air outlet.

3. The air cooling device as claimed in claim 2 , wherein each first pipe is at least partially disposed inside a corresponding second pipe of the at least two second pipes.

4. The air cooling device as claimed in claim 3 , comprising:
a sealed separation partition arranged between the at least two second pipes; and
at least two air distribution flaps arranged on either side of the sealed separation partition, respectively configured to distribute, for the corresponding air outlet, the first air flow and the second air flow that circulate in the first pipe and in the second pipe associated with the corresponding air outlet.

5. The air cooling device as claimed in claim 2 , wherein the first air flow and the second air flow are set into motion by a air propulsion component of the air cooling device or of a heating, ventilation and/or air conditioning installation configured to equip the motor vehicle.

6. The air cooling device as claimed in claim 5 , comprising at least one air distribution flap movably arranged so as to distribute an air flow rate between the first air flow and the second air flow.

7. The air cooling device as claimed in claim 6 , comprising an air flow feed canal, the air flow feed canal having:
a first branch dividing into the at least two first pipes; and
a second branch dividing into the at least two second pipes.

8. The air cooling device as claimed in claim 7 , wherein one of the at least two air distribution flaps is arranged between the first branch and the second branch of the air flow feed canal, so as to distribute the first air flow for the at least two first pipes via the first branch and the second air flow for the at least two second pipes via the second branch.

9. The air cooling device as claimed in claim 7 , comprising an additional air distribution flap movably arranged at a junction between the at least two second pipes between two end positions for closure of either one of the at least two second pipes, so as to distribute the second air flow circulating in the second branch between the at least two second pipes respectively associated with a distinct air outlet.

10. A heating, ventilation and/or air conditioning installation comprising the air cooling device as claimed in claim 1 .
