Abstract:
1. A vaporizer comprising: a vessel; a plurality of U-shaped tubes contained in the vessel, each tube having two ends, the U-shaped tubes being arranged in at least one plane; a plate disposed on one side of the vessel, the plate configured to close off said side of the vessel, wherein the plate has as many openings as there are tube ends, the openings comprising top openings and bottom openings, each U-shaped tube being linked by a top end to a top opening of the plate and by a bottom end to a bottom opening of the plate; and a dome covering the plate on a side opposite to that of the U-shaped tubes, the dome being delimited by a wall orthogonal to the plane of the U-shaped tubes to form an intake chamber and an exhaust chamber; wherein the intake chamber is divided into two parts by a partition at right angles to the plane of the U-shaped tubes and to the wall to form a liquid inlet chamber between the plate and the partition and an auxiliary chamber on the other side of the partition, a liquid inlet originating from outside the vaporizer and the liquid inlet opening into the inlet chamber and the auxiliary chamber being arranged to receive only a liquid originating from the inlet chamber so that the liquid originating from the outside arriving in the inlet chamber enters into the U-shaped tubes through the bottom openings only; wherein the partition comprises an opening toward its bottom edge to allow for a small circulation of the liquid between the partition and the dome.
