ABSTRACT:
The invention relates to a heat exchanger for two fluid media, especially liquids, having a housing which can be closed with a cover and which has a core for separately carrying the two media under heat exchange, at least the core being able to be produced by pressure casting. The core (3) is formed essentially of a train of walls in a meandering configuration which form the passages for the two media in the form of tall, narrow chambers, while the one medium and the other flow alternately through adjacent chambers. The chambers are divided into partial chambers disposed in two planes through which the fluid flows successively, by a common partition wall (34) which divides all the chambers vertically and is integral with the train of walls.
