A heat exchanger comprises a stack of spaced plates such that elongate plane-parallel fluid-conduit systems are established between adjacent pairs of plates, the plane-parallel conduit systems being in two sets, with the conduit system of one set being interposed between two conduit systems of the other set. Between adjacent plates, a conduit system is closed along its two laterally opposite edges, by rail-like spacers between the involved adjacent plates. The conduit system of at least one set comprises corrugated structures taking the form of extruded sections and having ridges which are connected to the lateral-edge closures of the involved conduit system.
