Abstract
A heat exchanger for counterflow and parallel flow is comprised of a plurality of stacks of form-stamped individual plates that are combined to pairs and the pairs are assembled atop one another to form the stacks. A first flow channel for a first medium is formed between the plates of each pair, and a second flow channel for the second medium is formed between adjacent pairs. The stacks are arranged directly adjacent to one another to form a stack assembly. Each first and second flow channel has an inlet and an outlet arranged diagonally opposite one another. The inlets and outlets of the first flow channels are arranged atop one another as are the inlets and the outlets of the second flow channels. The inlets and the outlets of the first flow channels are staggered relative to the inlets and outlets of the second flow channels by half a height of the pairs. Each stack has separating walls extending over the entire height of the stack for separating the inlets and outlets of the first flow channels from the inlets and outlets of the second flow channels. Cover plates connect the separating walls of neighboring stacks to form common collecting channels. The common collecting channels, including inlets and outlets at end faces of the stack assembly, are alternately connected to the inflow sockets and the outflow sockets of each medium so as to provide a separate flow passage for the first and the second medium.
