Heat exchanger tube with optimized plates

The heat exchanger tube (1) as claimed in claimed 2, wherein the partial blocking means (12) is defined by the shape of flow disturbers (15, 15a, 16, 16a) each with respect to the others in the circulation duct.

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 duot 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), wherein the partial blocking means (12) is defined by the shape of flow disturbers (15, 15a, 16, 16a) placed on both plates (4, 5) and wherein the plates (4, 5) are securely attached by the flow disturbers (15, 15a, 16, 16a).

A tube for a heat exchanger fanned from at least two plates connected to each other, the interior of the tube defining a circulation duct having at least one fluid inlet orifice and at least one fluid outlet orifice, wherein the interior of the tube comprises a means for partially blocking the circulating duct through which a fluid flows, to keep the cross section of the partially blocked circulation duct substantially constant between the at least one inlet orifice and the at least one outlet orifice, wherein the means for partially blocking the circulating duct are flow disturbers and wherein the flow disturbers are positioned such that the axes of the flow disturbers are offset along a vertical axis in the circulation direction of the fluid and the passage cross section is constant.
