Rörslingvärmeväxlare

A rörslingvärmeväxlare, or coiled tube heat exchanger, is a type of heat exchanger where fluid flows through a series of bent tubes or coils. These coils are typically arranged within a shell or a larger vessel. The primary function of this design is to facilitate efficient heat transfer between the fluid inside the tubes and another fluid or medium surrounding them.

The coiled structure maximizes the surface area available for heat exchange within a compact volume. This increased surface area allows for more rapid and effective transfer of thermal energy. The fluid path is often a continuous, winding tube, minimizing the number of connections and potential leak points.

Rörslingvärmeväxlare are commonly used in applications where space is limited or where high thermal efficiency is required. They can be found in industrial processes, HVAC systems, and even in some specialized chemical applications. The materials used for the tubes and shell depend on the specific fluids being handled and the operating temperatures and pressures. Common materials include various metals like stainless steel, copper, or titanium. The design allows for relatively easy maintenance and cleaning, although the complexity of the coiling can sometimes present challenges. The flow arrangement, whether parallel or counter-current, is a key factor in optimizing performance.
