Tube for a heat exchanger

A heat exchanger comprising at least one tube, the tube having a flattened configuration comprising a first essentially planar face and a second essentially planar face parallel to and spaced from the first face;

• both faces being connected by side walls where at least one face has a plurality of dimples configured according to a pattern that is repeated along the longitudinal direction X-X′ of the tube, where this pattern is configured by means of a plurality of groups of dimple alignments covering the width of the planar face, aligned according to one and the same direction Y-Y′ arranged obliquely between 40° and 50° degrees with respect to the longitudinal direction X-X′, and where it at least comprises:
• a first group which is formed by two dimples, a first elongated dimple extending according to the oblique direction Y-Y′ aligned with a first point dimple such that a first flow channel is established between the elongated dimple and the point dimple,
• a second group which is formed by four point dimples, a second point dimple, a third point dimple, a fourth point dimple and a fifth point dimple, essentially aligned according to the oblique direction Y-Y′, such that a second flow channel is established between the second point dimple and the third point dimple, a third flow channel is established between the third point dimple and the fourth point dimple, a fourth flow channel is established between the fourth point dimple and the fifth point dimple,
• a third group which is formed by two dimples, a sixth point dimple aligned with a second elongated dimple, extending according to the oblique direction Y-Y′, such that a fifth flow channel is established between the sixth point dimple and the second elongated dimple,
• a fourth group which is formed by four point dimples, a seventh dimple, an eighth dimple, a ninth dimple and a tenth dimple, essentially aligned according to the oblique direction Y-Y′, such that a sixth flow channel is established between the seventh point dimple and the eighth point dimple, a seventh flow channel is established between the eighth point dimple and the ninth point dimple, an eighth flow channel is established between the ninth point dimple and the tenth point dimple,
• where the position of the first flow channel is such that the flow going through same in the operating mode is mainly transported towards the third flow channel and the fourth flow channel.
