The utility model relates to a cross-gap multichannel aluminium pipe extrusion die. The cross-gap multichannel aluminium pipe extrusion die comprises an upper die 1, a die core 2 and a lower die 3, wherein the die core is embedded in the upper die through interference fit; a head of the die core is cone-shaped; three feeding holes are formed in the upper die; when mounting the die, one die bridge faces to a continuously-extruded plug. The cross-gap multichannel aluminium pipe extrusion die is a cross-hole aluminium pipe extrusion die which has the following advantages that the number of welding lines of an extrusion aluminium pipe is 3; when mounting the die, one die bridge faces to the continuously-extruded plug, so that metal flows more evenly; the metal is great in deformation in a deformation area and high in temperature, so that the extrusion speed can be improved; a cross-gap multichannel aluminium pipe can be directly extruded.
