MULTI-SHELL FLUID COLLECTOR FOR HEAT EXCHANGER WITH CIRCULATION OF THE FLUID COLLECTED BETWEEN THE SHELLS

摘要

The present invention relates to a heat exchanger fluid collector, in particular for a heat exchanger of a nuclear reactor, forming part of a first circuit of the heat exchanger. 'heat exchanger and comprising at least two adjacent shells separated by a plurality of studs which delimit a free volume, each free volume opening out by one of its ends on a first passage and by the other of its ends in a second passage, so that the fluid of the first circuit of the exchanger constitutes a cooling or heating fluid for the collector.
