[0028] Hereinafter, the embodiments of the present invention will be described in detail. An example of these embodiments is shown in the drawings. The embodiments described below with reference to the accompanying drawings are illustrative and are for explaining the present invention, but are not to be understood as limiting the present invention.

[0029] Hereinafter, a method for manufacturing a heat exchanger according to an embodiment of the present invention will be described with reference to the drawings.

[0030] As shown in FIGS. 1-11, the method for fabricating a heat exchanger according to an embodiment of the present invention includes the following operations.

[0031] In S100, a heat exchange module 200 is provided, the heat exchange module 200 including a plurality of micro-channel flattened tubes.

[0032] In S200, at least a part of the heat exchange module 200 is placed on the first platform 10, and a plurality of flat tubes are installed at intervals in the thickness direction (left-right direction in FIG. 1). Specifically, there is a gap between adjacent flat tubes. In addition, the first flow collecting tube 310 of the heat exchanger is provided at one end (rear end) of the flat tube of the heat exchange module 200 in the length direction (front-rear direction in FIG. 1), and the second flow collecting tube 320 of the heat exchanger is provided at the other end (front end) of the flat tube of the heat exchange module 200 in the length direction.

[0033] In S300, the position of the heat exchange module 200 is restricted in the width direction (front-rear direction in FIG. 1) of the first platform 10. As shown in FIG. 1, a portion of the heat exchange module 200 is placed on the first platform 10, and the rear end of the heat exchange module 200 is restricted in position by the first positioning tool 30.

[0034] In S400, the heat exchange module 200 is positioned in the length direction of the first platform 10. As shown in FIG. 1, the second positioning tool 40 protrudes upward or has a larger size in the vertical direction, and the second positioning tool 40 is inserted into the gap between the adjacent flat tubes of the heat exchange module 200 to position the heat exchange module 200. Specifically, there are multiple second positioning tools 40, and the multiple positioning tools are installed at intervals in the left-right direction, and there is a gap between the adjacent second positioning tools 40, and one flat tube is placed between two adjacent second positioning tools 40. In other words, the multiple second positioning tools 40 and the multiple flat tubes are installed at intervals in sequence, that is, there is one flat tube between two adjacent second positioning tools 40, and the second positioning tool 40 can move up and down.

[0035] In S500, a fin module 400 is prepared, the fin module 400 includes a plurality of fins, the plurality of fins are spaced apart in the length direction of the flat tube, the fin includes a plurality of slots spaced apart in the thickness direction of the flat tube, the slots penetrate the fin in the thickness direction of the fin, the flat tube is inserted into the fin slots, and the fin module 400 is moved so that one flat tube is inserted into one slot. As shown in Figures 2-5, while the fin module 400 is moving in the width direction of the flat tube (the vertical direction in Figure 1), the fin module 400 is placed on the first lever 50, and the first lever 50 penetrates the slots of the plurality of fins. After the flat tube contacts the second positioning tool 40, the second positioning tool 40 moves in the thickness direction of the first platform 10 (the vertical direction in Figure 1), or the size of the second positioning tool 40 in the thickness direction of the first platform 10 changes, so that the fin module 40 can continue to move in the width direction of the flat tube.

[0036] In S600, the pressing member 20 is used to press the heat exchange module 200, thereby moving the flat tubes a predetermined distance in the width direction of the first platform 10, the predetermined distance being equal to or greater than the maximum size of the first platform 10 of the fin module 400 in the width direction.

[0037] In S700, the pressing member 20 is used to press the heat exchange module 200, thereby moving the flat tubes a predetermined distance in the longitudinal direction of the first platform 10, the predetermined distance being equal to or greater than the maximum size of the fin module 400 in the longitudinal direction of the first platform 10.

[0038] For example, by using the pressing member 20 to press the heat exchange module 200, the flat tubes are moved a predetermined distance in the width direction of the first platform 10 (front-rear direction in FIG. 1), the predetermined distance being equal to or greater than the maximum size of the first platform 10 in the width direction of the fin module 400. Also, for example, by using the pressing member 20 to press the heat exchange module 200, the flat tubes are moved a predetermined distance in the length direction of the first platform 10 (left-right direction in FIG. 1), the predetermined distance being equal to or greater than the maximum size of the first platform 10 in the length direction of the fin module 400.

[0039] As shown in Figure 6, when the first drive component 2 is driven, the pressing member 20 moves to the right (left and right as viewed in Figure 6, which direction is also the width direction of the first platform, i.e., the front-to-back direction shown in Figure 1), and when pressed by the pressing member 20, the flat tube moves a predetermined distance to the right (i.e., forward in Figure 1), and the portion of the flat tube where the fins are assembled moves above the support assembly 70.

[0040] In S800, operations S500 and S600 are repeated, or operations S500 and S700 are repeated, until the installation of N fin modules 400 and one heat exchange module 200 is completed, where N is 2 or more.

[0041] In a processing method for a heat exchanger according to an embodiment of the present invention, after positioning the heat exchange module 200, one fin module 400 is assembled to a part of the heat exchange module 200, and a pressing member 20 is used to press the heat exchange module 200, and another fin module 400 is attached to another part of the heat exchange module 200 until the assembly of N fin modules 400 and the heat exchange module 200 is completed.

[0042] In the processing method for a heat exchanger according to an embodiment of the present invention, the fins required for one heat exchange unit or heat exchanger are attached by dividing them into flattened tubes, and the flattened tube group is moved to adjust the attachment position of each fin, so that fins can be attached without much restriction on the length or number of the flattened tubes.In addition, since the pressure received when dividing the fins into flattened tubes and attaching them is small, deformation of the fins can be reduced and crushing can be prevented.

[0043] As a result, the method for manufacturing a heat exchanger according to the embodiment of the present invention has the advantages of being highly versatile and having high assembly efficiency.

[0044] In addition, the operation symbols in the present invention are for the convenience of explanation and are not intended to limit the order of execution of each operation. In the present invention, the above operations can be performed in any order without conflict, and two or more operations can be performed simultaneously.

[0045] In some embodiments, as shown in FIGS. 2-5, operation S500 includes the following steps.

[0046] In S501, the fin module 400 is placed on the first lever 50, and the multiple fins contact the first lever 50. There are multiple first levers 50, and when the multiple fins contact the first lever 50, the first lever 50 passes through the multiple fin slots in sequence. Specifically, the fin slots open to one side in the fin width direction, and as shown in Fig. 1, the lower side of the fin slot is open, so that the flat tube can be inserted into the fin slot.

[0047] In S502, the first lever 50 and the fin module 400 are moved in the width direction of the flat tube. As shown in Fig. 4, the first lever 50 and the press-fitting tool 60 are simultaneously driven downward by an external force, so that the fin module 400 is moved downward.

[0048] In S503, the multiple fins of the fin module 400 contact the second positioning tool 40, and then the first lever 50 and the fin module 400 are separated. As shown in Fig. 5, after the multiple fins of the fin module 400 contact the second positioning tool 40, the first lever 50 moves to the left (i.e., rearward in Fig. 1) by the drive of the third drive component 5 until the first lever 50 is separated from the fin module 400.

[0049] In S504, the fin module 400 continues to move in the width direction of the flattened tube, and the flattened tube is inserted into the slot of the fin, while the second positioning tool 40 moves in the thickness direction of the first platform 10. As shown in Fig. 5, while the fin module 400 continues to move downward, the second positioning tool 40 moves downward by being driven by the second driving component 4, and while the fin module 400 moves downward, the flattened tube is inserted into the slot of the fin.

[0050] 3 and 11, in operation S501, or after operation S501 and before operation S502, the fins are arranged so that the gap between adjacent fins satisfies a predetermined value. Specifically, the fin module 400 is placed between the first plate 61 and the second plate 62, and the first plate 61 is moved to the right (i.e., forward in FIG. 1) to narrow the fins and arrange the fins so that the gap between adjacent fins satisfies a predetermined value, which is advantageous for positioning when attaching the fins.

[0051] In another embodiment, as shown in FIGS. 2-5, operation S500 includes the following steps.

[0052] In S501, the fin module 400 is placed on the first lever 50, and the multiple fins come into contact with the first lever 50. There are multiple first levers 50, and when the multiple fins come into contact with the first lever 50, the first lever 50 passes through the multiple fin slots in sequence. Specifically, the fin slots open to one side in the fin width direction, and as shown in Fig. 1, the lower side of the fin slot is open, so that the flat tube can be inserted into the fin slot.

[0053] In S502, the first lever 50 and the fin module 400 are moved in the width direction of the flat tube. As shown in Fig. 4, the first lever 50 and the press-fitting tool 60 are simultaneously driven downward by an external force, so that the fin module 400 is moved downward.

[0054] In S503, the multiple fins of the fin module 400 contact the second positioning tool 40, and then the first lever 50 and the fin module 400 are separated. As shown in Fig. 5, after the multiple fins of the fin module 400 contact the second positioning tool 40, the first lever 50 moves to the left (i.e., rearward in Fig. 1) by the drive of the third drive component 5 until the first lever 50 is separated from the fin module 400.

[0055] In S504, the fin module 400 continues to move in the width direction of the flat tube, and the flat tube is inserted into the slot of the fin, while the size of the first platform 10 in the thickness direction of the second positioning tool 40 decreases. In an embodiment of the present invention, while the fin module 400 continues to move downward, the size of the first platform 10 in the thickness direction of the second positioning tool 40 decreases, and the second positioning tool 40 may be a stretchable member, or may be another part or structural member that allows the size of the first platform 10 in the thickness direction to be changed.

[0056] Hereinafter, a heat exchanger processing apparatus 100 according to an embodiment of the present invention will be described with reference to the drawings.

In other words, the multiple second positioning fixtures 40 and the multiple flat tubes are installed at intervals in sequence, that is, there is one flat tube between two adjacent second positioning fixtures 40, and the second positioning fixtures 40 are movable up and down.
