Heat exchanger of plate stack structure

摘要

The heat exchanger consists of several plates which have openings and are stacked one above the other. It has flow channel plate units (1) with one or more flow channel openings (1a) against each other, extending between two plate side zones. There are also connecting channel openings (1b) which are separate from the flow channel openings. The heat exchanger also has connecting cover plate units (2) with connecting channel openings (2a-2d). The flow channel plate units and connecting cover plate units are stacked alternately above each other.
