Introduction
A brazed aluminium plate-fin heat exchanger consists of a block(core) of alternating layers (passages) of corrugated fins. Thelayers are separated from each other by parting sheets and sealedalong the edges by means of side bars, and are provided with inletand outlet ports for the streams. The block is bounded by capsheets at the top and bottom.
An illustration of a multi-stream plate-fin heat exchanger isshown in Figure 1-1.
The stacked assembly is brazed in a vacuum furnace to become arigid core. To complete the heat exchanger, headers with nozzlesare welded to the side bars and parting sheets adjacent to theports.
The size of a brazed aluminium plate-fin heat exchanger shall bespecified by width W, stacking height H and length L of therectangular block. (Figure 1-2).
The three dimensions shall be given always in the same sequenceas W x H x L, e.g. 900 x 1180 x 6100 mm.
