Heat exchanger has blocks multiple exchangers a fluid supply line as a uniform distribution, and the reboiler - condenser comprising such a heat exchanger

摘要

In such a heat exchanger in which the blocks of inlet windows of the fluid communication with the internal space of a manifold which extends against the block and which communicates with at least one box corresponding to a neighboring block to form a line for feeding fluid, in order to equalize the distribution of the fluid between the windows of the blocks, the power supply line contains at least one grid (30) with perforations (301) and of the solid parts (302) distributed in order to create headlosses such that the rates of flow of fluid in the inlet windows downstream of the grid have substantially equal values.
