Description

Technical Field

[0002] Large radiators are generally used in large engineering machinery or power station machinery and other equipment. The actual power of this type of equipment is large and the heat generated is large. Therefore, the working temperature control system is an important part of the entire equipment. The quality of its products directly affects the overall use effect of the machinery. Therefore, the brazing of the radiator is also very important. If the brazing quality of the radiator is unqualified, the size and structure of the radiator after brazing will change, making it difficult to carry out subsequent processes. At present, a jig frame is used for radiator brazing. Usually, a C-type clip is used to clamp the jig frame and the jig on the radiator core. However, the original clamping method of the jig is relatively complicated, the operation is cumbersome, time-consuming and labor-intensive, which reduces the clamping efficiency of the radiator core and is not practical. In addition, the original clamping device is easy to cause uneven force on the surface of the clamped radiator main plate, causing the radiator main plate to deform. At the same time, the radiator main plate will produce welding deformation during the brazing process. The existing clamping device cannot constrain the welding deformation generated by it, which greatly affects the welding quality of the radiator main plate. Summary of the invention
