Abstract
In order to create a space-saving, block-like heat exchanger duct bundle 14 from externally wired heat exchanger tubes without additional support structures, the heat exchanger ducts each consist of a core tube 3 having a coiled wire wrapping of wiring 16 extending over the entire length of the core tube (3), the turns of the coil are shaped so that the periphery of the wrapped coil has oppositely situated flat zones 13 to enable the ducts to be packed together. Preferably the peripheries of the wrapped coils are hexagonal in cross-section as shown so that the bundle forms a honeycomb structure.
