Abstract: The fluid distribution element according to the invention has a very low spatial requirement and simplifies the interlinked connection of multichannel pipes for the purpose of construction of a compact assembly for heat exchange. In particular the fluid distribution element according to the invention can be produced in a constructionally simple manner thus without, as in the state of the art, an increased risk of leakage arising at the interpenetration points. In order to prevent in addition possible pressure losses, the construction of the fluid-conducting device can be effected advantageously by means of the fluid distribution elements such that bionic attachments are followed in the line of the channel.
