Pipe forming part of a heat exchanger and heat exchanger comprising such a pipe

Abstract

The subject matter of the invention is a pipe ( 2 ) forming part of a heat exchanger. The pipe ( 2 ) is delimited by at least one wall ( 4, 7 ) for separating a fluid ( 3 ) circulating in the pipe ( 2 ) and an external medium ( 6 ). The wall ( 4, 7 ) is equipped with means ( 8 ) of deforming the wall ( 4, 7 ). These arrangements are such that at least one of the walls ( 4, 7 ) of the pipe ( 2 ) is actively deformed, in a precise and controlled manner, by the deformation means ( 8 ) in order to precisely conform and configure said, wall ( 4, 7 ), the use of the deformation means ( 8 ) being in particular placed under the influence of control means in relationship with the deformation means ( 8 ).
