Parallel tube heat exchanger having a baffle to modify direction and flow rate of an incoming process fluid

摘要

The heat exchanger 10 has a bundle of tubes 12 extending in parallel with one another between an intake header 13 and a discharge header, and an intake pipe 15 connected to the intake header. The intake pipe extends transversely to the axes of the tubes and has a first end opening into the header and a second end connectable to a process fluid supply pipe. A baffle 20 is arranged to modify the direction and flow rate of a process fluid through the intake header. The baffle is located at least partially within the intake pipe and is secured to the intake pipe adjacent the second end of the intake pipe, preferably by mounting spigots 22 connected to spacers 24 of a connection flange 16. The baffle may comprise a plurality of slats 26 extending between two runners 28 and may be rotatable about an axle (122, figures 5 and 6).
