Tube Register for Indirect Heat Exchange

摘要

A register for the indirect heat exchange between a utility fluid containing interfering components and a heat transfer fluid has at least one tube row with at least one flow channel with a small channel width and at least one flow channel with a large channel width. Additionally, in at least one tube row there is provided at least one flow channel with a narrow section defined by a small channel width as well as a wide section defined by a large channel width. The large channel width produces a large flow velocity of the utility fluid and the small channel width produces a small flow velocity of the utility fluid.
