Problems solved by technology

[0002] The edges and corners of the heat exchanger are usually protected by angle aluminum. The existing angle aluminum is generally formed by bending. During the bending process, the corners of the angle aluminum are prone to cracks, which reduces the quality of the angle aluminum and has a great impact on heat transfer. The protection effect of the device is not good

Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , figure 2 Shown, a kind of manufacturing method of heat exchanger angle aluminum comprises the following steps:

[0016] The first step: the angle aluminum body formed by bending the first panel 1 and the second panel 2 is obtained from the blank;

[0017] The second step: finely grinding the bending parts of the first panel 1 and the second panel 2 to form the thickened part 3 .

[0018] Step 3: Carry out fine grinding on the connection between the thickened part 3 and the first panel 1 and the second panel 2 again, and process the arc-shaped transition part 4, which avoids the stress at the edge of the thickened part 3 Concentrate, improve the quality of the angle aluminum.

[0019] The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of t...

Abstract

The invention relates to a manufacturing method for angle aluminum of a heat exchanger. Due to the fact that a thickening part is arranged at the bent position of the angle aluminum manufactured through the method, the phenomenon that the angle aluminum cracks during bending machining is avoided, the quality of the angle aluminum is improved, the service life of the angle aluminum is prolonged, and the effect on protecting the edges and corners of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the field of heat exchanger processing equipment, in particular to a method for manufacturing heat exchanger angle aluminum. Background technique [0002] The edges and corners of the heat exchanger are usually protected by angle aluminum. The existing angle aluminum is generally formed by bending. During the bending process, the corners of the angle aluminum are prone to cracks, which reduces the quality of the angle aluminum and has a great impact on heat transfer. The protective effect of the device is not good. Contents of the invention [0003] In view of the above existing problems, the applicant has carried out research and improvement, and provides a method for manufacturing a heat exchanger angle aluminum. The heat exchanger angle aluminum used for the support of the method of the invention has high quality, long service life, and is suitable for heat exchangers. It has the characteristics of good edge protection ef...
