Example Embodiment

[0024]The present invention is mainly aimed at the internal components of the tube side, so the shell side and working process are not described in detail in the implementation scheme, and the single-sided spiral insert has no specific requirements for the selection of the heat exchanger.

[0025]The installation process of the present invention: firstly, the double-sided spiral tie 1 and the single-sided spiral tie 2 are extruded by an extruder, and then the support frame 3 is inserted into the steel wire 10 to continue the subsequent extrusion process; The spiral tie 1 and the unilateral spiral tie 2 are put into the tube pass 7. The bilateral spiral tie 1 is close to the end of the tube pass, and the spiral tie 1 plays a role of supporting at the end. It should be ensured that the inner unilateral spiral tie 2 is in the tube pass. Keep stable in the process 7; finally fix the two ends of the steel wire 10 to the ends of the tube.

[0026]The working mode of the present invention is that w

Abstract

The invention discloses a novel low-water-resistance plug-in unit. The novel low-water-resistance plug-in unit mainly comprises a steel wire, a single-side spiral link and supporting frames. A plug-inunit body is the single-side spiral link with a certain length, a water inlet and a water outlet adopt a small part of double-side spiral links, and the middle portion of the plug-in unit body adoptsa certain number of supporting frames to fix the links at the position of a tube pass. The novel heat exchanger plug-in unit has the beneficial effects that the heat exchange efficiency is not influenced as much as possible, meanwhile, the resistance of the links to water flow is reduced, the energy consumption problem caused by the links is greatly reduced, meanwhile, the edge structure of the single-side spiral plug-in unit is improved, and the abrasion consumption of the edge of the single-side spiral plug-in unit during working is reduced; and then the energy loss of the whole process isreduced, and the overall efficiency is improved. According to the novel low-water-resistance plug-in unit, in the working process of the single-side spiral link, the tube pass can still drive fluid micelles to do spiral motion under the action of the links, and the purpose and effect of enhancing heat exchange are achieved.
