  • Patent number: 12384223
    Abstract: A thermal regulation circuit for a vehicle includes a first heat exchanger, a second heat exchanger, and a third heat exchanger. The first and the second heat exchangers are situated in series such that an ambient air flow passes through the first heat exchanger prior to passing through the second heat exchanger. The ambient air flow also passes through the third heat exchanger. The thermal regulation circuit is configured to allow a refrigerant fluid to circulate through the first heat exchanger and then the third heat exchanger. The thermal regulation circuit is configured to allow a heat-transfer fluid to circulate through the second heat exchanger.

  • Patent number: 11059354
    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).
