Description

Technical Field

[0001] The invention particularly relates to a processing device for a refrigerator evaporator. Background Art

[0002] The refrigerator evaporator is one of the core components of the refrigerator refrigeration system. It is responsible for absorbing heat from the inside of the refrigerator to lower the temperature. The evaporator is usually made of copper tubes or aluminum tubes, with fins on the surface to increase the heat exchange area. The fins are mostly set on one side of the pipe. In order to increase the heat dissipation area, some fins are formed by cutting on both sides of the pipe.

[0003] In the existing process of processing the fins of the evaporator, the two ends of the evaporator are fixed to limit the random movement of the evaporator during cutting. However, when cutting an evaporator with a longer length, the middle part of the evaporator will be compressed and bent, resulting in quality problems and poor processing results. In addition, when processing the fins on both sides of the evaporator, it is necessary to rotate and turn over the evaporator body after processing one side. At this time, it is necessary to release the clamping force at both ends of the evaporator in advance and then clamp and fix it after turning over. The operation is relatively cumbersome. For this reason, we propose a processing device for a refrigerator evaporator. Summary of the invention
