Description

Technical Field

[0001] The utility model relates to the field of fin molding, in particular to a fin molding device for a heat exchanger. Background Art

[0002] Heat exchanger fins are a type of component used to increase the heat exchange area in a heat exchanger. They are usually installed on the outside of the tubes of the heat exchanger to form a finned tube structure. The finned tube heat exchanger increases the surface area of ​​the tube by adding fins, thereby improving the heat exchange efficiency.

[0003] In the process of producing the fins of the heat exchanger, a stamping mold is usually used to stamp the fins to form them into a curved shape. However, when the existing molding device opens the mold, the profile will be subjected to stamping pressure when bending, and the profile will fit together with the module, which will lead to the problem of difficulty in demolding the profile. Utility Model Content

[0014] Furthermore, the support block is fixedly mounted on the top end of the support rod, the top surface of the support block is designed to be U-shaped, and the support block is located between the molding modules.

[0015] Furthermore, one side of the first module and one side of the third module are provided with grooves, and the left and right sides of the second module are provided with the same grooves, and the cross section of the groove is designed to be V-shaped.
