1. A device (2) for transferring heat comprising:
a thermally conductive plate (30) capable of capturing the heat from a zone placed on a first side (32) of the plate (30),
at least one fin (35) placed on a second side (34) of said plate (30) opposite to the first side (32), said at least one fin including;
a conduit (36) extending in a longitudinal direction (L) between a first end (38) connected to said plate and a second end (40) opposite to the first end and which opens out,
a plurality of wall elements extending laterally from said conduit and forming at least one Venturi-effect neck (42) for supplying cooling air into the conduit through at least one orifice in the conduit, said Venturi-effect neck (42) being formed in the vicinity of the first end of said conduit and of said plate.
