1. A device for thermally regulating an electrical component, the temperature of which needs to be regulated, said electrical or electronic component being liable to release heat during its operation, the thermal regulation device comprising:
a housing that extends along a longitudinal axis and is configured to accommodate at least the electrical or electronic component;
an air flow outside of the housing along the longitudinal axis;
a circuit for a dielectric fluid;
a device for spraying said dielectric fluid onto the electrical or electronic component, wherein the phase-change temperature of the dielectric fluid is such that it is able to vaporize on contact with the electrical or electronic component;
a condensation wall, formed by a portion of the housing, having an internal face and an external face, wherein the condensation wall is configured to condense the dielectric fluid in its vaporized form using internal reliefs and external reliefs,
wherein the internal reliefs protrude or are recessed from a plane in which the internal face of the condensation wall is inscribed and are configured to increase a heat exchange surface area of the internal face thereby optimizing a first heat transfer between the dielectric fluid in its vaporized form and the condensation wall, and
wherein the external reliefs protrude or are recessed from a plane in which the external face of the condensation wall is inscribed and are configured to increase a heat exchange surface area of the external face thereby optimizing a second heat transfer between the condensation wall and the air flow outside of the housing.
