System or module for exchanging thermal energy between two flowing media, particularly for decentralized ventilation of work rooms, has folding heat exchanger with folded surface profile that passes through in folding direction as piecewise

摘要

The system or module has a folding heat exchanger with a folded surface profile. The folded surface profile passes through in folding direction as piecewise under a direction. The folded surface profile encloses an angle of greater than 0 degree, particularly 90 degrees with the direction. A component also extends piecewise in a direction. The folding height of an individual fold of the folded surface profile varies.
