However, the above pairs of passages are separated from one another. In case where the above-mentioned basic plates are laid one above another in a predetermined order, the passages within the plate A may communicate with those within another plate A through the passages within the plate B or C and may further communicate with those witin a still lower plate A in series in a helical fashion. The same thing can be said about the passages within the plates B and C. For instance, it is possible to form a three-layer heat exchanger having such structure that the passages within the plate B lie below the plate A and the passages within the plate C lie above the plate A.
