Publication number: 20240001469Abstract: A heat exchanger includes a fluid flow tube configured to allow an exchange of heat between the fluid flowing in the tube and an enclosure surrounding the tube. The enclosure is formed from two profiled bars configured to surround the tube over at least one part of its length. Each of the bars includes a recess adapted to receive the tube, and a joint surface configured to form a joint with the other profiled bar. The joint surfaces of the profiled bars form a gap therebetween. As well, the joint surfaces of the profiled bars are arranged in different planes such that the gap forms at least one baffle on each side of the tube.Type: ApplicationFiled: July 5, 2023Publication date: January 4, 2024Applicant: LIEBHERR-AEROSPACE TOULOUSE SASInventors: Julien ROBERT, Stéphane MEUNIER, Arnaud RAMOUSSE
