    • A plate-fin heat exchanger (18) having alternating layers (60, 98) for exchanging heat between fluids to be warmed against fluids to be cooled. One or both of the layers (60, 98) is subdivided into flow passages (116, 118, 120, 122, 124) to allow for the flow of two or more fluids (40a, 40b, 44a, 44, 48a, 48b) flowing through one of the layers (98) to engage in indirect heat transfer with one or more fluids (16) flowing through another adjacent layer (60). The flow through the heat exchanger (18) is parallel to the width of the heat exchanger (18). The first and second layers (60, 98) provide a greater cross-sectional flow area for each of the fluids than otherwise would have been provided had the fluids flow been parallel to the length of the heat exchanger (18) with layers (60, 98) thereof dedicated to the flow of each of the fluids.
    • 具有交替层(60,98)的板翅式热交换器(18),用于在被加热的流体与要冷却的流体之间进行热交换。 层(60,98)中的一个或两个被细分成流动通道(116,118,120,122,124),以允许两个或更多个流体(40a,40b,44a,44,48a,48b)的流动, 流过一个层(98)以与一个或多个流过另一相邻层(60)的流体(16)接合间接传热。 通过热交换器(18)的流动与热交换器(18)的宽度平行。 第一层和第二层(60,98)为每种流体提供更大的横截面流动面积,而不是如果流体与热交换器(18)的长度平行,层(60, 98)专用于每种流体的流动。
