The invention relates to a device, comprising at least one flow chamber (20) having an inlet opening and an outlet opening, said flow chamber being provided for the flow of a medium therethrough. The flow chamber (20) is arranged in a single-piece block element (2) and is at least partly delimited by a diathermal wall in order to effect absorption or release of thermal energy through the wall by means of the medium. The at least one flow chamber (20) is formed in the block element (2) from a plurality of first channels (22) spaced apart from each other, which extend straight and parallel to each other, and a plurality of second channels (23) spaced apart from each other, which extend straight and parallel to each other, the first and the second channels (22, 23) each having two ends and being closed at least at one (27) of the two ends. The second channels (23) are arranged at an angle to the first channels (22), the first channels and the second channels thus crossing. Support pillars (21) having a parallelogram-shaped cross-section are present within each flow chamber (20) between the crossing points of two adjacent first channels (22) and two adjacent second channels (23). A turbulent flow of the medium can be produced very effectively in the device according to the invention.

A heat exchanger is disclosed herein that includes three walls that are each shaped in a wave pattern with the waves that extend in both a first lateral direction and a second lateral direction. A second wall is adjacent to and in contact with a first wall with the waves of the second wall being offset from the waves of the first wall by one-half wavelength in the first direction. The third wall is adjacent to and in contact with the second wall with the waves of the third wall being offset from the waves to the second wall by one-half wavelength in the second direction. The first wall and second wall form a first plurality of flow paths extending in the second direction, and the second wall and the third wall for a second plurality of flow paths extending in the first direction.

The present invention puts the first heat exchange plate (1) and the second heat exchange plate (2) in interference connection through the engagement between the snap projection (9) and the snap groove (10), which effectively ensures stability and reliability of the connection, and ensures the airtightness of the connection.

A counter-current cross-flow heat exchanger for heating a first gas and cooling a second gas, includes modules in fluid communication with one another, each module being positioned on a plane, the planes mutually overlapping. Conduits allow entry and exit of the first and second gases into and out of the exchanger. Each module has heat exchange plates, with heating and cooling faces. The plates are orthogonal to the module plane and parallel to define alternating heating and cooling spaces. The first gas crosses each heating space with a direction substantially parallel to the plane of each module and the second gas crosses each cooling space with a direction substantially orthogonal to the plane of each module. The cooling spaces between adjacent modules are in direct fluid communication. The heating spaces between adjacent modules are in fluid communication with one another by conduits/conveyors, creating a serpentine path.
