The invention relates to a device (10, 50) intended for modifying the temperature of an object (1) including at least two areas (2, 3) brought to different temperatures, said device (10, 50) including a heat-transfer fluid and at least one plate (11, 51) crossed by said fluid and intended for coming into contact with said object (1). The main feature of a device according to the invention is that the plate (11, 51) comprises means for circulating said fluid making it possible to differentiate at least two separate portions (12, 13, 52, 53) of said plate (11, 51) each having its own capacity to vary the temperature of one of the areas (2, 3) of said object (1), said plate (11, 51) coming into contact with the object (1) so as to reduce the temperature differences between the various areas (2, 3) of said object (1).
