<p>A heat exchanger comprises a plurality of substantially similar plates provided with dimples or other projections (42) in opposite directions from both faces and with a pair of ports (50, 52) each plate (10) being turned at 90° relative to the adjacent one so that the ports (50, 52) align to provide a pair of separate series of flow paths which are interleaved between the plates (10), the angular alignment being controlled by the square shape and the axial spacing of the plates (10) by the projections (42) contacting one another. The plates are clamped together and sealed for example by furnace brazing.</p> |
