Abstract
A method for manufacturing an annular heat exchanger intended to be mounted on the radially inner or outer face of an annular shell of a casing of a double-flow turbomachine, the method including: obtaining by extrusion a heat exchanger preform by a die shaped so that the preform includes: first pipes for the circulation of a fluid to be cooled, second pipes arranged on either side of the first pipes in a direction perpendicular to the direction of extrusion; making a hole from the outside in the preform, the hole leading into one of the second pipes of the preform; and introducing into the hole of the second given pipe a member for partially closing off its passage cross-section.
