Abstract (en)

The exchanger has pipes that are helically wound in multiple concentric pipe bearings (4, 7) around a core barrel. A casing limits an outer area around the pipes and is designed in such a manner that heat is transferred between two fluids in operation, where the fluid flows through interior of one of the pipes and through the outer area. Non-heat transferring flexible units (1a, 1b) are arranged in the interior of the exchanger and connected with the pipes, where the units are designed as spiral springs.
