HEAT EXCHANGER

摘要

The invention relates to a heat exchanger (1) for vaporising a liquid by exchanging heat with a fluid, comprising: a body including an assembly of plates (3) disposed parallel to a pre-determined direction (11) defining therebetween a plurality of passages (4, 5), comprising a first group of passages (4) intended for the flow of the liquid and a second set of passages (5) intended for the flow of the fluid; a retention tank (2) for receiving the liquid; elements (6) for the primary distribution of the liquid, designed to distribute the liquid from the retention tank (2) to the first group of passages (4); elements (7a) for the secondary distribution of the liquid, located in the first group of passages (4); and means for establishing fluid connections between particular zones (14) and a gas tank located outside the exchanger (1), such as to allow pressure balancing between the tank and the zones (14).
