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 efficiency of a rörirörväxlare depends on factors like the surface area for heat transfer, the flow
