The invention relates to a method for manufacturing a metal foam provided with at least one channel and intended, in particular, for the manufacture of a heat exchanger from a preform (1) of beads. A central portion (2), consisting of a core (3) and a coating made of a low-temperature meltable material is arranged in a casting mold, then the preform is arranged around the central portion while establishing close contact with said central portion, the low-temperature meltable material is then removed via heating, the molten metal mass is then poured into the mold in order to fill in the free spaces between the beads and between the beads and the core (3), and then the beads are finally removed. |
