Abstract (en)

[origin: GB2328732A] A heat exchanger comprises at least one layer (13, 33) of substantially parallel conduits laid on a base plate (11). Two sidewalls (12A, 12B) are positioned on the base plate (11) with the conduits (13) lying between and substantially parallel to the sidewalls (12A, 12B). The sidewalls are formed by stacking a plurality of flat shims (12C, 12D, 12E) on the base plate (11) and the height of the sidewalls (12A, 12B) so formed is such that the conduits (13) extend above the sidewalls (12A, 12B). Atop plate (20, 40) is positioned on the so-extending upper surfaces of the conduits (13, 33). Heat and loading are applied to the composite structure so formed while in a vacuum to deform the conduits (13, 33) to reduce their height, whereby the conduits bond to the plates (11, 20, 40). The conduits may be arranged in a plurality of groups (figure 5) separated by spacer bars (206).
