Abstract

The invention discloses an expanded tube welding production method of a simple evaporator, which comprises the steps of bending a U-shaped tube, punching, shearing and mounting fins, mounting each component of the evaporator, expanding the tube, welding and the like. The method is simple and rigorous to operate, through a simple and clear self-inspection program, the quality of materials in each step is guaranteed, the yield is increased, and the production cost is reduced; In the welding process, the welding quality is ensured by controlling the temperature and selecting welding rods, and the sealing performance of products is ensured.

Description

technical field [0001] The invention relates to the field of evaporator production and processing, in particular to a simple evaporator expansion tube welding production method. Background technique [0002] Finned evaporator is an important heat exchange device, which is widely used in various heat exchange systems. A finned evaporator is mainly composed of fins and U-shaped tubes interspersed in the fins. Because the U-shaped tubes will pass high-pressure liquid during use, in order to avoid liquid leakage affecting other components of the heat exchange system, for The sealing requirements are very high. In the existing simple evaporator, the tightness of the material and parts often fails to meet the requirements during the expansion tube welding, and the yield rate is low. Contents of the invention [0003] In view of the problem of insufficient sealing of the simple evaporator in the prior art mentioned above, a simple evaporator expansion tube welding production me...
