ABSTRACT:
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 the lower end of the other set of passages and caused to flow upward. The ends of the heat exchanger plates are split into two end portions which are 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. In making the exchanger, the exchanger plates are arranged in substantial parallelism and edges joined together with clips which tie the plates together as a unit bundle. A layer comprising a mixture of synthetic plastic resin and reinforcing material is prepared, and the unit bundle of plates is placed with a set of longitudinal edges of the plates in such layer. When the resin hardens, the layer forms a rigid slab extending along such set of edges which seals the edges to the heat exchanger housing with an air tight seal.
