Abstract: The heat transfer capacity of a cross-flow heat exchanger can be increased by changing or graduating the density of the fins that form a row of hot passages in the direction normal to those fins. In accordance with some embodiments, the fin density in each row of hot passages is lower in a first region near the cold air inlets than it is in a second region located between the first region and the cold air outlets. This has the beneficial effect of increasing the rate of flow of hot air through hot passages adjacent or near to the cold air inlets of the heat exchanger, i.e., where the temperature of the cold air is coldest. As cold air flows along each cold passage, the cold air is heating up, becoming less capable of cooling the hot air in the adjacent hot passages as it gets closer to the cold air outlets. In addition or alternatively, the cold passages may have a non-uniform fin density that increases heat transfer capacity.
