A kind of deformation process of aluminum alloy S-shaped fin tube

Abstract

A deformation process for producing aluminum alloy finned tubes. The fins of the aluminum alloy fin tube are folded or curled during extrusion molding, and the fins are rolled flat by special machinery after extrusion. An airfoil with the same performance will use a smaller mold, so that the airfoil can be produced thinner and save material.

Description

Technical field [0001] The invention relates to a deformation process for producing an aluminum alloy fin tube. It is used for extruding aluminum alloy finned tubes by extruders. It belongs to the international patent class F28F3 / 00 "general heat exchange or parts of heat exchange equipment". Background technique [0002] At present, the production method of aluminum alloy finned tube is extrusion molding. During the forming process, the minimum thickness of the airfoil is related to the diameter of the mold. The minimum thickness of fins with larger molds is limited during production. For example, when making a single-sided fin of 90 mm according to the traditional process, the root is 1.5 mm and the end is about 1.0 mm. [0003] The optimal size of the theoretical calculation of the fins on the aluminum alloy finned tube used in the evaporator is 1 mm in thickness at the root and 0.3 mm in the end.
