Porous blocker bar for plate-fin heat exchanger

摘要

A plate-fin heat exchanger adapted to reduce thermal fatigue is described. The plate-fin heat exchanger includes a cold fluid pathway running along a first axis, a hot fluid pathway running along a second axis perpendicular to the first axis, and at least one porous blocker bar running along the first axis. The porous blocker bar includes a set of pores adapted to control the flow along the hot fluid pathway and coupled to an inlet of the hot fluid pathway.
