The utility model relates to a heat dissipation aluminum tube used in an automobile engine intercooler, in particular to a high-frequency welding intercooler heat dissipation aluminum tube. The high-frequency welding intercooler heat dissipation aluminum tube comprises a heat dissipation aluminum tube body, wherein the heat dissipation aluminum tube body is provided with a compound brazing layer, the inner portion of the heat dissipation aluminum tube body is provided with a turbulent flow inner fin, the turbulent flow inner fin and the heat dissipation aluminum tube body are melt into a whole through the compound brazing layer, and the turbulent flow inner fin enables a single lengthways wave to be divided into a plurality of staggered waves by a wave-shaped inner fin conducting a plurality of across cutting, overcomes the defect that air flow of the heat dissipation aluminum tube is sacrificed in order to achieve larger heat absorption area of the inner fin, and realizes the purpose of saving raw material.
