HEAT EXCHANGER

摘要

A heat exchanger, particularly useful as a packed bed catalytic reactor, comprises a stacked assembly of plates, the stack having an inlet (12) and an outlet (14) for a first fluid and an inlet (24) and an outlet (34) for a second fluid, characterised in that a first portion of the assembly is formed of one or more perforated plates (26), each first perforated plate (26) having two alternating series of slots (36, 46), whereby the series of slots (36, 46) define two separate passageways for said two fluids, the first series of passageways being connected to said inlet (12) and outlet (14) for the first fluid, a second portion of the assembly being formed of one or more second perforated plates (20, 22, 20A) having first (36A, 36B) and second (46A, 46B) series of slots corresponding to the slots of the first plate(s), each slot (46A, 46B) of the second series opening at one of its two ends into a feeder slot (50, 50B) extending across the second plate, the feeder slot(s) being connected to an inlet (24) or an outlet (34) for the second fluid.
