Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger that is easy to maintain. Background Technology

[0002] In traditional heat exchangers, elbows are commonly used to connect the heat dissipation tubes, and all connections are fully welded. This connection method necessitates the additional welding of sealing plates at pressure-bearing points. If a leak occurs, repairs become extremely difficult. Locating the weld at the pressure-bearing point requires cutting the sealing plate, which is not only complex and time-consuming but also causes significant damage to the overall structure of the heat exchanger.

[0003] After repair, the sealing plate needs to be re-welded, which makes it difficult to restore the appearance of the heat exchanger. The welding process may even damage the sealing plate, affecting the heat exchanger's sealing performance and service life. This series of problems makes the maintenance of traditional heat exchangers costly and difficult, becoming a major challenge for both users and manufacturers. Utility Model Content
