Cooling system for a vehicle lighting module

A vehicle lighting module comprising at least one cooling system including at least one heat sink and at least one axial-circulation member for axially circulating a fluid, the heat sink including a first heat-dissipating surface which extends in a first plane of extension and a second heat-dissipating surface which extends in a second plane of extension secant with the first plane of extension, at least a thermal-dissipation member projecting from the first dissipating surface, at least one wall which, with the axial-circulation member and with the second dissipating surface, at least partially delimits a fluid-circulation chamber for the fluid, which opens via a fluid outlet onto the thermal-dissipation member or members, and at least a first light source thermally connected to the first dissipating surface and at least a second light source thermally connected to the second dissipating surface, with the heatsink including a first wall having an upper face that forms the first dissipating surface and a lower face opposite the upper face, the first light source or sources being borne by the first dissipating surface, a second wall having a front face and a rear face opposite the front face, the second light source or sources being borne by the front face and the rear face forming the second dissipating surface, the lower face adjacent to the front face.
