TEMPERATURE CONTROL DEVICE

The invention relates to a heat exchange and transfer device that consists of a closed cavity containing a biphasic fluid and includes: at least one heat exchange area comprising a flat chamber configured in the shape of a space, the size of which is significantly smaller than the other two, typically at least ten times smaller, said flat chamber having a first capillary structure on all or part of the inner surface thereof, enabling the fluid in the liquid form thereof to wet said first capillary structure, at least one heat transport area configured in the shape of at least one tube having a second capillary structure over all or part of the inner face thereof, said flat chamber and said at least one tube being connected such that the vapor can circulate freely in the entire cavity, and that capillarity continuity is ensured between the first and second capillary structures so that the liquid can wet the entire resulting capillary structure.
