Abstract
A method for manufacturing a tubular distributor of a heat exchanger in which the distributor is formed by layers of material between which the ends of heat exchange tubes of a matrix are secured in fluid-tight manner. The layers are made of fibers which are juxtaposed between the tube ends of adjacent rows and the layers are deformed by compression so that they each engage around one-half of the associated row of tubes to form an initially porous structure into which a metallic material is injected to integrate the fibers of the layers with one another and with the ends of the tubes in sealed relation.
