rørslangevarmevekslere

Rørslangevarmevekslere, also known as coiled tube heat exchangers or simply tube-in-tube heat exchangers, are a type of heat exchanger where one fluid flows through a series of tubes that are themselves contained within a larger shell through which a second fluid flows. The tubes are often bent into a spiral or coiled shape to increase the surface area for heat transfer within a compact volume. This design maximizes the contact between the two fluids, facilitating efficient heat exchange.

The principle of operation involves the transfer of thermal energy from the hotter fluid to the colder fluid across the tube walls. The fluids are kept separate, preventing any mixing, which is crucial for applications where contamination is a concern. Rørslangevarmevekslere are commonly used in various industrial processes, including chemical processing, food and beverage production, and HVAC systems. They are particularly well-suited for handling viscous fluids or fluids with suspended solids, as the smooth, unobstructed flow path through the tubes minimizes fouling and clogging.

The materials used for the tubes and shell can vary depending on the application and the fluids being handled, with common choices including stainless steel, copper, and various alloys. The efficiency of a rørslangevarmeveksler can be influenced by factors such as the length and diameter of the tubes, the number of coils, and the flow rates of the two fluids. Their robust construction and relatively simple design contribute to their reliability and ease of maintenance in many demanding environments.
