Abstract: A cooling device for a system for cooling electronic components partially immersed in a dielectric fluid, including a first heat exchanger. The first heat exchanger is configured to be partially immersed in the dielectric fluid and includes a first circuit for a first heat-transfer fluid. The cooling device also includes a second heat exchanger configured to be in contact with a part of the electronic components, the second heat exchanger being fluidically connected to the first heat exchanger in such a way that the first heat exchanger and the second heat exchanger together form a second circuit for a second heat-transfer fluid.

Abstract: A heat exchanger including a cooling plate configured to be in contact with electronic components and includes a circulation channel for a first heat-transfer fluid, and includes a two-fluid exchanger with a first fluid circuit in fluidic communication with the circulation channel of the cooling plate to form a circulation loop for the first heat-transfer fluid, and a second fluid circuit configured to receive a second heat-transfer fluid. The heat exchanger can also include an additional cooling plate arranged in contact with the two-fluid exchanger, and at least one heat-transfer element arranged between the additional cooling plate and a second part of the electronic components.

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.

Abstract: Thermal regulation circuit for a vehicle, said circuit comprising first (2) and second (4) heat exchangers that are situated in series along a direction of circulation of an air flow intended to pass through them in this order, said circuit comprising a third heat exchanger (6) intended to be passed through by an ambient air flow, said circuit being configured to allow a refrigerant to circulate in series in the first (2) and third (6) heat exchangers and a heat-transfer fluid to circulate in the second heat exchanger (4).

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).
