Abstract (en)
[origin: WO2016113491A1] In a diode lighting module (10) comprising an array of diodes (12) mounted on a support plate (14) and heat dissipation means for dissipating heat released by the diode array, a metal plate (22) is provided, an external face of which is in contact with said support plate and an internal face supports a metallic honeycomb foam (24) comprising a plurality of graded holes (24A) crossing each honeycomb cell in two perpendicular directions and a housing (26) forming a vessel, filled with the metallic honeycomb foam and for which the metal plate constitutes the cover, the housing comprising inlet and outlet openings crossing the housing in order to receive a cooling liquid and a separator (28) defining, in the metallic honeycomb foam, two separate circulation regions for the cooling fluid, one region for the inflow of the cooling fluid and one region for the back-flow of the cooling fluid, the passage from one region to the other taking place at a cut-out (28A) in the separator.
