A method of manufacturing a layered structure of a plate-fin heat exchanger comprises stacking (figure 8) a first sheet 150, second sheet 154 and third sheet 152 such that the third sheet 152 is positioned between the first 150 and second sheets 154. Regions of the third sheet 152 are bonded to the first sheet 150 and the second sheet 154. Recesses 162 are provided in an outer surface of the first sheet 150 and/or the second sheet 154 at a position corresponding to the respective regions bonded to the third sheet 152. The first sheet 150, second sheet 154 and third sheet 152 are placed in a die and a hollow structure is formed (figure 9) so that the third sheet 152 spans a gap between the first 150 and second sheets 154 to define channels of the heat exchanger. The first 150 and/or second sheet 154 are pressed against a surface of the die so as to remove the recesses therefrom (see figure 10). |
