A heat exchanger for exchanging heat between first and second fluids. A plurality of vertically oriented passages are defined between alternating first and second passage walls. The first and second passages are provided for bringing the first and second fluids into a heat transfer relationship. To this end, the first passage incorporates an inlet and an outlet, for instance, to admit gaseous nitrogen into the top of the first passages and to discharge condensed nitrogen from the bottom of the first passages. An inlet is provided to introduce the second fluid into the second passages. The second fluid, which is a liquid is to be at least in part vaporized within the second passages. Liquid film, composed of the liquid, is distributed within the second passages by way of an arrangement of slotted dividing bars having staggered slots along the length of such slotted dividing bars to urge liquid against the passage walls defining the passages. Additionally, or in place of the dividing bar arrangement, a multi-domain corrugated fin material arrangement can be provided to effect a liquid film distribution within the second passages.

[ We claim:] [1.] A heat exchanger for exchanging heat between first and second fluids, said heat exchanger comprising:a plurality of vertically oriented, spaced apart passage walls defining a plurality of alternating first and second passages located between said passage walls to respectively receive said first and second fluids in an indirect heat transfer relationship;first inlet and outlet means for respectively introducing and discharging said first fluid into and from said first passages;second inlet means for introducing said second fluid into said second passages as a liquid;slotted dividing bars located between said passage walls defining said second passages, said slotted dividing bars having spaced, vertically oriented slots to cause said liquid to flow against said passage walls defining said second passages, thereby to enhance formation of liquid film on said passage walls; andeach of the slotted dividing bars having a lengthwise extending peak to cause the liquid to flow towards the slots andsecond outlet means for discharging said second fluid from said second passages after having indirectly exchanged heat with said first fluid.
