<p>Indirect heat exchange is effected between media flowing in two or more annular spaces formed between coaxiel tubes extending between upper and lower distributor heads and coupled therewith by annular clips. One medium enters from a port in a distributor end face into a chamber from which it flows into an outer annular space, and also an axially entered in a space reached via a necked sleeve forming an extension from an inner tube. A second medium for co. or counter flow with the first, enters the distributor head via a radial lateral port for delivery into an intermediate annular space. Exchanger tube ends abut against periphery ledges formed in an internal distributor wall or at the broad end of the sleeve. The leads have internal arcuate chambers leading to the inter tube spaces.</p> |
