HEAT EXCHANGER

摘要

Thermo acoustic device comprising a heat exchanger for transferring thermal energy between a first fluid in a first fluid circuit and a second fluid in a second fluid circuit. The first fluid circuit and the second fluid circuit are connected to each other in a thermally conductive manner. The first and second fluid circuits are formed by a stack of plate elements (11, 12, 13) which form first channels (6a, 6b) for the first fluid circuit and a plurality of channels (3) for the second fluid circuit. The sum total of cross sections of the plurality of channels (3) takes up at least 25% of a front surface of the second fluid circuit.
