Embodiment 1

[0048] This embodiment provides an implementation scheme and an assembly method of a quick positioning tool for tube fins of a heat exchanger.

[0049] This embodiment provides a tube fin positioning tool for heat exchanger, as attached figure 2 As shown, it includes a bracket 101, a driving mechanism and a set of sliders 102 for fixing flat tubes. The slider 102 is installed on the bracket 101 and can move along the axis of the bracket 101 . The sliders 102 are provided with racks 106 , and adjacent sliders are meshed with each other through the racks 106 and gears 107 . attached figure 2 It is only a schematic structural diagram of this embodiment, which has been simplified without affecting the understanding of the technical solutions of the embodiment. The bracket 101 in the figure only shows the fixed shaft connected to the slider, omitting the main body of the bracket and appendix. Similarly, in all the drawings, several tube fins are used to express the technical so...

Embodiment 2

[0061] This embodiment provides an implementation scheme and an assembly method of a quick positioning tool for tube fins of a heat exchanger.

[0062] This embodiment provides a tube fin positioning tool for a heat exchanger, such as Figure 4 As shown, it includes a slider bracket 201 , a set of sliders 202 , a tube holder composed of a bottom plate 203 and a tie rod 204 , a tie rod shaft 205 and a pressure plate 206 . The slider 202, the bottom plate 203, the pull rod 204, the pull rod shaft 205 and the pressing plate 206 together form a driving mechanism for driving the movement of the tube fin.

[0063] The pipe holder is a chute formed by the bottom plate 203 and the pull rod 204. One end of the chute is fixed, and the other end is provided with a wrench which can be turned to change the height of the chute. The width of the pull rod matches the thickness of the installed flat tube, and the flat tube can be fixed by inserting it on the chute. After the fin assembly is c...

Embodiment 3

[0074] This embodiment provides an implementation scheme and an assembly method of a quick positioning tool for tube fins of a heat exchanger.

[0075] This embodiment provides a tube fin positioning tool for heat exchanger, as attached Figure 8 As shown, it includes a bracket 301, a driving mechanism and a set of sliders 302 for fixing the flat tube.

[0076] The slider 302 is installed on the bracket 301 and can move along the axis of the bracket 301 . A slot 303 matching the thickness of the flat tube is also provided on the slider 302 to fix the flat tube 1 of the heat exchanger. A gasket 304 is provided on one side of the slot 303 . Using different thicknesses or numbers of spacers, the thickness of the slots or grooves can be adjusted to accommodate flat tubes of different thicknesses.

[0077] The driving mechanism in this embodiment is composed of a cam 305 between adjacent sliders and a connecting rod 306 connecting the sliders and the cam. Turning the cam 305 dr...

Abstract

The invention relates to a finned tube assembly technique method for manufacturing heat exchangers, provides a finned tube locating fixture of a heat exchanger, and aims to solve the problems that the operation efficiency is low, and dislocation is easy to occur when a group of finned flat tube bundles is tightened and assembled to a collecting tube. The finned tube locating fixture comprises a bracket, a driving mechanism and a group of tube fixators, wherein each tube fixator is provided with at least two locating points; and the tube fixators can be driven to move between a first locating point and a second locating point through the driving mechanism so as to drive each flat tube to reach the position corresponding to the slot of the collecting tube. Each flat tube and fin in the front and back directions are uniformly stressed and tightened through the finned tube locating fixture; the group of finned flat tube bundles is tightened at a set distance and position quickly, accurately and uniformly; the finned tube locating fixture is simple and reasonable in structure; and the production efficiency and precision of a finned tube locating assembly process are improved.

Description

technical field [0001] The invention relates to a manufacturing process of a heat exchanger, in particular to a tube-fin assembly process in the manufacture of a parallel flow heat exchanger. Background technique [0002] The parallel flow heat exchanger is composed of porous flat tubes, cooling fins and headers. Both ends of the flat tube are respectively inserted into the left header and the right header, and separated by partitions arranged on the left header and the right header to form a series channel. The surface of fins and collectors is coated with solder and flux, and the entire core is clamped by a fixture and welded as a whole through a brazing furnace. Parallel flow heat exchangers were mainly used in automobile air conditioners in the early days, and have also been widely used in commercial air conditioners, household air conditioners, coolers and other fields in recent years. [0003] During the processing of the parallel flow heat exchanger, the flat tubes,...
