Abstract
A plate-fin heat exchanger having alternating layers for exchanging heat between fluids to be warmed against fluids to be cooled. One or both of the layers is subdivided into flow passages to allow for the flow of two or more fluids flowing through one of the layers to engage in indirect heat transfer with one or more fluids flowing through another adjacent layer. The flow through the heat exchanger is parallel to the width of the heat exchanger. The first and second layers 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 with layers thereof dedicated to the flow of each of the fluids.
