Abstract
A cooling device having a surface configured to allow the circulation of a heat-transfer fluid along the surface in a first direction D1, an exchange of heat being able to take place by convection between the cooling device and the fluid, the device includes n cooling fins, n being an integer greater than or equal to one, each cooling fin forming a protuberance of the device, extending primarily in a plane (P) containing the first direction (D1), in each fin, at least two inserts having a tube form and a dimension characteristic of a section of the tube and extending primarily in a second direction (D2) of the plane P distinct from the first direction (D1), the inserts having, over their greater length, a thermal resistance lower than the thermal resistance of the cooling fin along the same length, each insert being distant in the first direction (D1) from another insert by a length equal to or greater than the characteristic dimension of the section of the tube of the insert.
