Abstract

A heat exchanger for exchanging heat between first and second fluids, the heat exchanger comprising: a plurality of vertically oriented, spaced apart passage walls defining a plurality of alternating first and second passages located between the passage walls to respectively receive the first and second fluids in an indirect heat transfer relationship; first inlet and outlet means for respectively introducing and discharging the first fluid into and from the first passages; second inlet means for introducing the second fluid into the second passages as a liquid; slotted dividing bars located between the passage walls defining the second passages, the slotted dividing bars having spaced, vertically oriented slots to cause the liquid to flow against the passage walls defining the second passages, thereby to enhance formation of liquid film on the passage walls; and each of the slotted dividing bars having a lengthwise extending peak to cause the liquid to flow towards the slots and second outlet means for discharging the second fluid from the second passages after having indirectly exchanged heat with the first fluid.
