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.

Multichannel flat tube for heat exchanger

The invention relates to a heat exchanger for vehicles. The heat exchanger includes a core provided with a row of spaced heat exchanger tubes, open at their ends, and at least one dosed container arranged in the tube end regions for the distribution of a medium flowing through the heat exchanger tubes. Each container includes a tube holding element and a container closure element, connected to each other in a sealed manner. The heat exchanger tubes are put through the tube holding element, connected to it and form spaces between each other. The container closure element is rigidly connected to at least one associated container comb, the teeth of which extend toward the heat exchanger core and are located within the container-interior at the spaces between the heat exchanger tubes and are in rigid connection to at least the tube holding element.
