Abstract: 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.

Abstract: The invention relates to a plate heat exchanger (1) configured for a heat exchange between a first fluid flowing in a first pass and a second fluid flowing in a second pass, the fluids flowing between two external plates (2), comprising a plate exchanger block comprising a plurality of internal plates (12, 14) arranged substantially in parallel with each other, said internal plates being arranged substantially in parallel with the external plates (2), characterized in that it comprises at least one lateral encapsulation plate (20) extending substantially orthogonally to said internal plates, each lateral encapsulation plate being fixed in contact with said external plates (2) so as to laterally close said second pass.
