The two different media can flow reversely (or in the same direction) in the tube pass to achieve the heat exchange effect, and the inner tube in the concentric sleeve is used as the heat exchanger of the heat transfer element. Two kinds of pipes with different diameters are sleeved together to form a concentric sleeve, each section of sleeve is called one-pass, the inner pipe (heat transfer pipe) of the pass is connected in a row by a short pipe in sequence by a U-shaped elbow, and the outer pipe is fixed on a bracket. Heat is transferred from one fluid to another through the inner tube wall. Typically, hot fluid (A fluid) is introduced from the upper portion, while cold fluid (B fluid) is introduced from the lower portion. The two ends of the outer tube in the sleeve are welded or flanged with the inner tube. The inner tube is connected with the multipurpose flange of the U-shaped elbow, so that the heat transfer tube is convenient to clean and increase and decrease. The effective length of each heat transfer tube is 4-7 meters.
