Vorrichtung zur Zirkulation eines Fluids

摘要

A heat exchanger casing (1) has a square or rectangular end opening into an inlet or outlet plenum for flowing fluid, the plenum wall being made up of at least one section (20A) of a sphere or ellipsoid and a plurality of sectors (22A) of cones welded together tangentially to each other and to casing (1). The heat exchanger comprises an array of parallel flat plates separating alternate spaces for respective fluid flows, one set of spaces opening into the plenum to connect these spaces with inlet or outlet (27).
