The utility model discloses a header pipe, including the sandwich layer aluminum pipe and the pipe of brazing, the sandwich layer aluminum pipe is seamless aluminum alloy tube, brazing, closely the parcel is on seamless aluminum alloy tube's outer wall or inner wall through the aluminium strip material of brazing for the pipe, and the both sides reason that the aluminium strip material of just brazing is relative forms the tubulose through welded connection. The utility model discloses a thermal treatment and physics mode combined tensile extrusion of high pressure and high temperature thermaltreatment technology to make the sandwich layer and the layer of brazing combine closely simultaneously earlier stage to realize the seamless purpose of sandwich layer, fundamentally has avoided because the flog soldering joint that the high -frequency soldering caused is revealed, improves header pipe's mechanical properties and resistance to corrosion. 本实用新型公开了种集流管，包括芯层铝管和钎焊管，所述芯层铝管为无缝铝合金管，所述钎焊管通过钎焊铝带材紧密包裹在无缝铝合金管的外壁或内壁
