ABSTRACT:
The invention relates to a multi-channel flat tube for heat exchangers that contains at least two channels extending along its length and arranged essentially adjacent to each other along its width passable by fluid, or at least two channel sections formed by one or several of said channels, whereby between the channels or the channel sections over the length of the flat tube one region of reduced heat transmission in each case is provided, characterized by that the region of reduced heat transmission is defined by a connecting web and isolating channels arranged on both sides of the connecting web. The transverse heat conduction within the flat tube is reduced by this arrangement.
