Problems solved by technology

[0004] The disadvantages of this spiral bond processing technology are: 1. When the rotary stretching device is driven to rotate, the pitch of the sheet is affected by factors such as the rotating speed of the rotary stretching device, the number of revolutions, and the conveying speed of the sheet, and the final spiral bond is formed. Several screw pitches (equivalent to the turbulence unit referred to below) are not exactly the same. After such helical ties are installed in the tu

Abstract

The invention belongs to the technical field of heat exchanger equipment and relates to a machining process for flow spoiler bands. The machining process comprises the steps of edge cutting treatment, preheating treatment, sheet material prewire crush-cutting, twisting treatment, reversed twisting treatment, air-cooling sizing and final trimming. Firstly, prewires are adopted for the machining process to standardize the length of flow spoiler units, the flow spoiler units of a finished flow spoiler band are the same in length, the turbulent flow force on fluid in different positions in a tube bundle is the same after the flow spoiler band is mounted in the tube bundle, and heat exchanging is more even; secondly, according to the scheme, a conventional rotary stretching device is omitted so that the situation that a sheet material is twisted off due to a conventional rotary stretching method is avoided; and thirdly, due to the fact that a cross section is formed in the process of sheet material prewire crush-cutting, the overall superficial area of the sheet material is increased, the contact area between the molded flow spoiler band and cold air is larger when the molded flow spoiler band passes by an air cooling mechanism, and the cooling effect of the flow spoiler band is improved.
