rörirörväxlare

A rörirörväxlare, which translates to "pipe-in-pipe heat exchanger" in English, is a type of heat exchanger where one pipe is placed concentrically inside another, larger pipe. The two pipes form separate channels for the flow of two different fluids. Heat transfer occurs between these two fluids as they flow through the exchanger, either in parallel or countercurrent directions. The inner pipe carries one fluid, while the space between the inner and outer pipe carries the other.

This design is particularly effective for transferring heat between liquids or between a liquid and a gas. The construction is relatively simple and robust, making it suitable for a variety of applications. Rörirörväxlare are often used in industrial processes, such as in chemical plants, food processing, and HVAC systems. They can be employed for heating, cooling, condensation, or evaporation tasks.

The efficiency of a rörirörväxlare depends on factors like the surface area for heat transfer, the flow rates of the fluids, and the temperature difference between them. Cleaning and maintenance can be straightforward, as the design often allows for easy access to the fluid channels. Due to their simplicity and reliability, they remain a common choice for many heat exchange needs.
