Heat exchanger and heat transfer in a compact design

Heat exchanger module in a compact configuration, characterized in that (I) at least two planar partition plates (2) of a height dimension (H) and a width extent (B) and at least three between the partition plates (2) located, mutually non-contacting outer (3) and inner (3 ') of spacer plates of respective same depth dimension (T) but different width extent (B) are fixedly connected together, wherein the outer spacer plates (3) throughout its height extent (H) and overall width dimension (B) with the partition plates (2) are in contact, but only on a bonding surface , are fixedly connected to a width dimension of 10 to 90% of the contact surface, (Ii) at least two cross-plates (5) with the partition plates (2) on top of each of the spacer plates (3, 3 ') facing away side are securely connected, wherein the cross-plates (5) with the partition plates (2) (in its entire width dimension B ) and the entire height extent (H) are in contact, but only on a joint surface, (with a height dimension H) of 10 to 90% of the contact surface are rigidly connected, (Iii) two outer boundary plates (6) with greater depth dimension (T) than those of the partition plates (2), with the respective outer lateral plates (5) are firmly connected in the same manner as with the partition plates (2), and (Iv) wherein the bonded firmly together two boundary plates (6, 6 '), two outer spacer plates (3), at least two partition plates (2) and at least two cross-plates (5) a solid frame along with the respective connecting surfaces (10) in the form form an integrated frame.
