Abstract (en)
[origin: EP0449783A2] The heat exchanger (10) consists of congruent planar elements (16) stacked one upon another at a distance (a) by means of inserted or integral projecting spacers. For the purpose of forming inflow cross-sections (30), these planar elements are cantered twice at right angles in the same direction on the mutually opposite sides, and turned by 90<o> to one another in each case. The cantered limbs (16') embrace the nearest planar element (16). Three of these planar elements (16) form in each case two adjacent flow ducts (34, 36) having flow directions (20, 22) intersecting at right angles. At least on the inlet side (E) of the medium flows (20, 22), the inflow cross-sections (30) are folded in for the most part without changing the external dimensions of the heat exchanger (10). The inflow cross-sections (30) remain unfolded only in the region of the edges (28) extending vertically relative to the planar elements (16). In each case, at least one adjoining planar element (16) is clamped in a sealing fashion in the longitudinal fold (24). <IMAGE>
