    • The invention relates to a method for producing a tube for a heat exchanger, in particular for a motor vehicle, in which a long tube, which is provided with turbulence inserts on the surface thereof, is separated into at least two individual tubes. In order to further reduce the production costs and nevertheless achieve a clean cutting surface, a first part of an at least two-part cutting device is introduced into the interior of the long tube through at least one opening of the long tube and the second part of the cutting device is placed against the outer face of the long tube approximately opposite of the inner, first part of the cutting device, wherein the first part and the second part of the cutting device are pressed against one another in order to dividing the long tube.
    • 本发明涉及一种用于制造用于热交换器,特别是用于机动车辆的管的方法,其中在其表面上设置有湍流插入件的长管被分离成至少两个单独的管。 为了进一步降低生产成本并且实现清洁的切割表面,至少两部分切割装置的第一部分通过长管的至少一个开口被引入长管的内部,而第二部分 所述切割装置抵靠所述长管的外表面大致与所述切割装置的所述内部第一部分相对,其中所述切割装置的所述第一部分和所述第二部分被彼此压靠以便将所述长的 管。
