The utility model relates to a heat radiation aluminum pipe arranged on an automobile generator intercooler, in particular to an intercooler high frequency welding rectangular aluminum pipe. The intercooler high frequency welding rectangular aluminum pipe comprises a heat radiation aluminum pipe and an inner fin. A composite brazing layer is arranged on the surface of the heat radiation pipes and/or the inner fin. The inner fin is zigzag-shaped and arranged inside the heat radiation aluminum pipe and integrated with the heat radiation aluminum pipe composite brazing layer. Compared with an extrusion harmonica aluminum pipe, under the same technical requirement, the intercooler high frequency welding rectangular aluminum pipe is capable of saving raw materials by 20-30 percents, lighter than the extrusion harmonica aluminum pipe, high in production efficiency (50/70 meters m/min) and low in electric power consumption and the like, capable of needing no addition of brazing materials and simplifying processing t
