Abstract:
1. A heat exchanger for vaporizing a liquid by exchanging heat with a second fluid, the heat exchanger comprising: a parallelepipedal body formed of an assembly of parallel vertical plates and lateral bars defining between the parallel vertical plates a multitude of flat passageways and the lateral bars closing off the passageways to the outside, wherein the lateral bars extend vertically with the parallel vertical plates and are perpendicular to the parallel vertical plates; means for sending the liquid into a first set of passageways and the second fluid into the remaining passageways; and a packing element configured to distribute the liquid at the top end of the passageways of said first set, over the whole horizontal length of said passageways, by a fine distribution over the whole length of these passageways; wherein at least one of the lateral bars has, toward the inside of the exchanger, a rounded profile over most of its length and a flat profile over a portion of its length, wherein the flat profile is disposed on the lateral bars away from the inside of the exchanger as compared to the rounded profile thereby creating a cutout, and in that one edge of the packing element extends past the rounded profile and into the cutout.
