<p>A flat-plate heat exchanger having first and second groups of the plates (10 and 11), the plates of one group being interleaved with those of the other group. Each of the plates (10 and 11) is formed within one face with a fluid flow passage (13 and 20), the passage (13, 20) being constituted by a plurality of channels (18 and 25) which are formed within the thickness of the plate (10, 11). The fluid flow passages (13) within the first group of plates (10) extend between side edges (15 and 17) of the plates (10, 11) and, in so doing, the passages (13, 20) make an odd number of transverse passes across the width of the plate (10, 11), and headers (27 and 28) are located at the respective side edges of the heat exchanger for directing a first heat exchange fluid into and from the fluid flow passages (13) in the first group of plates (10). The fluid flow passages (20) in the second group of plates (11) extend from one end (22) of the plates (11) to the other end (24), in a linear direction.</p> |
