VERTICAL COUNTERFLOW HEAT EXCHANGER APPARATUS A counterflow heat exchanger is described with two sets of heat exchanger passages separated by heat exchanger plates disposed in substantial parallelism within the exchanger and supported so that the passages extend substantially vertically. The heat exchanger may be employed as an air-to-air or as an air-to-water heat exchanger and can be used to remove moisture or pollutants from hot exhaust air by condensation within the exchanger passages. When employed as an air-to-water heat exchanger, the water is sprayed onto the surfaces of the upper ends of one set of passages so that it flows down their length, while air is transmitted into inlets at the lower end of the other set of passages and caused to flow upward out of outlets at the upper end thereof. The ends of the heat exchanger plates are split into two end portions separated by a divider member and joined to different exchanger plates on opposite sides thereof to form the two sets of passages which allow the air and water to flow in opposite directions through such passages for counterflow heat exchange by direct lateral transfer through the thickness of the exchanger plate. |
