Heat exchanger such as plate-, straight-tube- or coiled heat exchanger for indirectly exchanging the heat between natural gas and heating- or cooling fluid, has passages for gaseous or liquid fluids, bundles of tubes, and container shell

摘要

The heat exchanger such as plate heat exchanger, straight-tube heat exchanger or coiled heat exchanger for indirectly exchanging the heat between natural gas and heating fluid or cooling fluid, comprises passages for gaseous or liquid fluids, bundles of tubes, which are coiled around a core tube in concentric layers of tubes, and a container shell, which limits an outer space around the tube. The passage has flow resistance present at the lower and/or upper ends in the interior of the passage. The flow resistance is a mechanical component, which clogs the flow of the gaseous or liquid fluids.

The passage has flow resistance present at the lower and/or upper ends in the interior of the passage. The flow resistance is a mechanical component, which clogs the flow of the gaseous or liquid fluids flowing in the passage. The tube has a flow resistance present at the lower and/or upper ends in the interior of the tube and at the tube inlet and/or tube outlet. The tubes of the outer, the middle and/or the inner tube layers have the flow resistance at the lower and/or the upper tube ends.
