Description

Technical Field

[0001] The utility model relates to the technical field of condenser tubes, and in particular to a three-dimensional low-fin composite fin condenser tube. Background Art

[0002] In the fields of petrochemicals, air conditioning, refrigeration, etc., the condensation of steam from different media on the outer surface of the tube bundle is often involved. In the condensation heat transfer process, the condensate generated by the condensation of steam forms a liquid film to cover the wall surface. Therefore, the condensation of steam can only occur on the surface of the condensate. The latent heat released during condensation must pass through this liquid film to be transferred to the cold wall. However, when the thermal resistance of steam condenses outside the tube is large, the condensation effect will be reduced. Therefore, the thermal resistance of condensation heat exchange is mainly concentrated outside the heat exchange tube. Therefore, the research on enhanced condensation heat exchange tubes is mainly aimed at condensation outside the tube, and the outer fins of the finned tube can destroy the continuity of the condensation liquid film, thereby enhancing the condensation heat transfer performance outside the tube.

[0003] After searching, a Chinese patent with publication number CN 220119934 U discloses a three-dimensional low-wing composite fin condenser tube, which is relatively simple to process and prepare, is suitable for low temperature and corrosive environments, and has a good condensation effect; it includes a condenser tube body, the condenser tube body includes a steel inner tube and an aluminum outer tube, the aluminum outer tube is tightly sleeved on the outer periphery of the steel inner tube, and continuous spiral fins are rolled circumferentially on the outer wall of the aluminum outer tube, the fin height is 0.5mm~2.0mm, and the fin width is 0.3mm~1.5mm.

[0004] Although the above-mentioned three-dimensional low-fin composite fin condenser is relatively simple to process and manufacture and is suitable for low-temperature and corrosive environments, it is difficult to replace the fins if they are deformed or corroded, and when the condenser is connected to the external pipeline, leakage often occurs due to insufficient sealing of the connection.
