<p>. A heat exchanger, particularly for use in heat pumps, either as evaporator or as condenser or both, comprises for the flow of a refrigerant one or more pipes helically coiled around a core pipe. This structure is mounted inside a mantle-pipe which serves for the flow of a heat carrying medium, such as water, and is helically coiled around a vertical axis or bent to another compacted shape making the center line of the turns of the helically coiled pipe or pipes extend horizontally or at a slight inclination to horizontal. The refrigerant is fed to one end of the helically coiled pipe or pipes and then flows back through the core pipe. The heat carrying medium flows through the mantle-pipe in the same general direction as the flow of refrigerant through the helically coiled pipes.</p> |
