Abstract:
A tube (1) for a heat exchanger (2) through which a fluid (3) flows, intended to promote heat exchange between an external medium (7) and said fluid, formed by at least two plates (4, 5) connected to each other in order to define a circulation duct (10), the cross section of which is a cross section (11) for passage of said fluid, said circulation duct having a fluid inlet orifice (13) and a fluid outlet orifice (14), wherein said tube comprises a means (12) for partially blocking the circulation duct (10) to keep the passage cross section (11) of said duct substantially constant between the inlet orifice (13) and the outlet orifice (14) and wherein the partial blocking means (12) is defined by the staggered positioning of flow disturbers (15, 15a, 16, 16a) each with respect to the others such that their cumulated blocking cross sections are substantially constant over the entire length of the circulation duct (10).
