Flat tube for use in motor vehicle, has parallel lower channels that are connected on both sides of transversal partitions, and bound by walls of tube and separated from each other by partitions

摘要

The tube has a set of parallel lower channels (24, 26) including transversal sections (S1, S2) for controlling fluid pressure existing in the channels, where the channels are connected on both sides of transversal partitions (30) that have uniform thickness. The channels are bound by walls (28, 32) of the tube and separated from each other by the transversal partitions. An independent claim is also included for a heat exchanger including flat tubes.
