The bent evaporators may not meet the process requirements, such as uneven copper tubes that make it impossible to assemble the bent tubes, and misalignment of the screw holes on the side plates that makes it difficult to drive the screws. These problems affect the next process and seriously reduce production efficiency. Utility Model Content
