Abstract:
Tube-block-type heat transfer device, havinga tube block consisting of several tubes which are arranged in a row in the transverse direction side-by-side in a spaced manner and are designed to be flat at least in their end areas,spacing elements which are inserted between two respective adjacent flat tube end areas and are firmly connected with them, andin each case at least one connection duct along each transverse tube block side,wherein the tubes are sealed off on their ends and are provided with transverse openings in their two end areas, which transverse openings are in a connection-duct-forming connection with spacing element transverse openings,wherein at least one pair of separation spacing elements which are situated opposite one another in the same space between adjacent tubes is constructed in a closed manner without a continuous transverse opening and, as a result, on each transverse side of the tube block, at least two mutually separated connection ducts are formed for the separate flowing of plural fluids through pertaining tube block sections, andwherein the spacing elements associated with one tube end are connected together and are disposed at opposite sides of said one tube end with mutual contact of adjacent spacing elements between respective tubes.
