RW tube bundle heat exchangers consist of a bundle of high-performance corrugated tubes made of copper or copper-nickel, which is brazed into a copper or copper-nickel housing. The special corrugated tubes manufactured by Schmöle have a large number of troughs or corrugations which are stamped into the tube wall from the outside. The resulting structures on the outer and inner surfaces ensure significantly improved heat transfer compared to plain tubes. Deflector plates are used to generate an outer flow around the tubes in the shell space.
RW tube bundle heat exchangers are manufactured in six different capacity sizes, with the outer diameter of the shell tubes and the overall height being the same for all capacity sizes. The construction length, which varies according to the capacity, can be seen in Figs. 1 and 2.
