The present invention relates to a multi-tube manufacturing device and a method for manufacturing a multi-tube using the same, wherein a header is fabricated by inserting an insertion pipe into a containing pipe and is extruded by a ram using a predetermined extrusion force, the header is heat-treated by a heat treatment unit, and the heat-treated header is drawn by a drawing unit using a predetermined drawing force so as to produce a multi-tube having a desired diameter such that a plurality of tubes are simultaneously coupled mechanically and metallurgically by means of relatively simple configuration and process, thereby producing a multi-tube economically. |
