no. 1 example

[0074] will now refer to Figures 1 to 2b The first embodiment is described.

[0075] According to this first embodiment, at least one distribution flap 19 is arranged inside the associated atomizing duct 9 so as to move between the following positions:

[0076] - at least one closed position blocking the first air flow F1 (see Figure 2a );and

[0077] - Multiple locations called open locations (an open location in Figure 2b shown in ), which allows adjustment of the flow rate of the air flow F1 carrying the droplets of the atomized liquid for the respective associated air outlet 7 .

[0078] In particular, at least as many distribution flaps 19 as air outlets 7 are provided. More particularly, according to this first embodiment, at least one distribution flap 19 is arranged within each atomizing duct 9 associated with an air outlet 7 . The distribution flaps 19 are respectively configured to regulate the flow rate of the air flow F1 carrying the droplets of the liquid ...

no. 2 example

[0084] The second example is Figures 3 to 4c shown. refer to Figures 1 to 2b The description of the first embodiment applies to the same components. Differences between the first and second embodiments will now be described.

[0085] Unlike the first embodiment, in which the same amount of air flows in the first duct 9 or in the second duct 15 irrespective of the position of the distribution flap 19, the air cooling device 1 according to the second embodiment allows both in and inside The amount of air circulating in the first duct 9 and the second duct 15 associated with a given area is adjusted without affecting the air circulating in the first duct 9 and the second duct 15 associated with another area in the interior , or even vary or remain constant at other locations.

[0086] More particularly, according to this second embodiment, the cooling device 1 is configured differently for each air outlet 7 and thus for each diffuser 8 ( Figures 3 to 4c not shown in ), di...

no. 3 example

[0120] The third embodiment is for example Figure 5 shown. refer to Figures 1 to 4c The descriptions of the first and second embodiments are applicable to the same components. The points of difference of the third embodiment will now be described as compared to the foregoing embodiments.

[0121] according to Figure 5 In the example shown, the control cooling device 1 comprises two first ducts 91 and 92 associated with second ducts 151 , 152 respectively. In this third embodiment, the configuration of the air cooling device 1 differs in particular from the other embodiments in that it comprises an air flow feed channel 125 having:

[0122] - a first branch 127 which splits to form said two first ducts 91 and 92; and

[0123] - A second branch 129 which divides to form said two second ducts 151 and 152 .

[0124] Furthermore, in this third embodiment, the single distribution flap 119 allows the flow of the first air flow F1 carrying the droplets of the liquid to be ato...

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 (F1, F2) 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 (F1) 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 (F1) 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; 91, 92).

Description

technical field [0001] The invention relates to an air cooling device for a motor vehicle. The invention also relates to a heating, ventilation and / or air conditioning installation comprising such an air cooling device. Background technique [0002] In order to ensure the thermal comfort of the vehicle occupants, for example, motor vehicles often include ventilation and / or air conditioning facilities which allow a lower temperature to be established inside than the outside temperature. [0003] These ventilation and / or air conditioning facilities exchange cooled air to provide thermal comfort for the vehicle occupants. A first disadvantage of such installations is that the air being cooled is dry. Furthermore, the seats located in the rear of the interior are generally not so well ventilated so that they are not cooled well. It should also be noted that not all vehicles are necessarily provided with an air conditioner. [0004] In order to improve the situation, it is kn...
