The invention relates to a flat tube heat exchanger, in particular to a high-temperature flat tube heat exchanger for gaseous media, comprising a closed housing (5) having a tube bundle space (50) and a tube bundle, arranged in the tube bundle space (50) of the housing (5), comprising multiple flat tubes (2), there being arranged, in the flat tubes (2) and in the tube bundle space (50) between the flat tubes (2), corrugated strips (3, 6) having peaks (30, 60) and troughs (31, 61) extending in the longitudinal direction of the flat tubes (2), wherein the peaks (30, 60) and troughs (31, 61) respectively bear internally and externally against flat sides (200) of the flat tubes (2), and wherein there is provided a device for externally applying a surface pressure to the housing (5), at least in the region of the tube bundle space (50), this pressure being higher than a pressure (p1, p2) of the media guided in the flat tubes (2) or around the flat tubes (2).
A flat-tube heat exchanger, in particular for gaseous media, comprising a closed housing having a tube bundle space and a tube bundle which is arranged in the tube bundle space of the housing and which comprises a plurality of flat tubes, wherein corrugated bands having peaks and troughs extending in a longitudinal direction of the flat tubes are arranged in the flat tubes and in the tube bundle space between the flat tubes, wherein the peaks and troughs bear internally or externally against flat sides of the flat tubes, and in that provision is made of an apparatus which is suitable, and configured, for externally applying a surface pressure to the housing, at least in the region of the tube bundle space said surface pressure being higher than a pressure of the media guided in the flat tubes or around the flat tubes.
