[0030] Example:
[0031] The microchannel fin heat exchanger includes a microchannel fin module, which has a continuous "S"-shaped curved structure. When manufacturing the microchannel fin module, it is necessary to process the columnar aluminum wire into a continuous S-shaped curved structure and use a specific processing mold to improve production efficiency. The columnar aluminum wire (the material is selected according to the use requirements) is wound around the processing mold to form a continuous S-shaped curved microchannel fin module to improve production efficiency. At the same time, the shape and size of the microchannel fin module produced by the mold are more standardized and more consistent.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a microchannel fin heat exchanger processing mold includes a main body 1, the main body 1 includes a base 10, and a processing assembly 20 is provided on the base 10. The processing assembly 20 includes a plurality of first positioning columns 21 and a plurality of second positioning columns 22 arranged at intervals. The first positioning columns 21 and the second positioning columns 22 are arranged in a one-to-one correspondence, and a groove 23 is formed between the first positioning columns 21 and the second positioning columns 22.
[0033] Specifically, in one embodiment, an integrated structure is adopted between the base 10 and the processing assembly 20, that is, the microchannel fin heat exchanger processing mold is integrally cast from metal material or other applicable materials, the plurality of first positioning columns 21 are arranged at equal intervals, and the plurality of second positioning columns 22 are also arranged at equal intervals, and the spacing between the first positioning columns 21 is equal to the spacing between the second positioning columns 22. The plurality of first positioning columns 21 are arranged one-to-one with the plurality of second positioning columns 22, that is, each first positioning column 21 is arranged opposite to a second positioning column 22, and a groove 23 is formed between the first positioning column 21 and the second positioning column 22, and the groove 23 is an equidistant straight groove, that is, the spacing between each pair of first positioning columns 21 and second positioning columns 22 (a first positioning column 21 and a second positioning column 22 arranged correspondingly) on both sides of the groove 23 is equal. The gaps between the first positioning posts 21 and the gaps between the second positioning posts 22 are used to allow the columnar aluminum wire to pass through the gaps and wrap around the first positioning posts 21 and the second positioning posts 22 when winding the microchannel fin module. The grooves 23 are used to place the spacer 2 after a complete winding. When in use, a winding direction is set, and winding from the first first positioning post 21 in the set winding direction along the gap to the last second positioning post 22 is considered to be a complete winding.
[0034] As a way to achieve this, Figure 2 , Figure 4 and Figure 5 As shown, the main body 1 is formed by a plurality of first limiting plates 11 and a plurality of second limiting plates 12 which are staggered and stacked with each other, the first limiting plates 11 and the second limiting plates 12 both include a substrate forming the base 10, the first limiting plate 11 includes a first substrate 111 forming the base 10, the second limiting plate 12 includes a second substrate 121 forming the base 10, the first substrate 111 and the second substrate 121 are provided with mounting holes 13 for connecting the plurality of first limiting plates 11 and the plurality of second limiting plates 12 and forming the processing mold main body 1, the plurality of first limiting plates 11 and the plurality of second limiting plates 12 are connected and fixed by arranging fastening bolts 3 in the mounting holes 13 in the plurality of first limiting plates 11 and the plurality of second limiting plates 12, one end of the fastening bolt 3 is provided with a bolt head, the bolt head is clamped on the outside of the mounting hole 13, the other end of the fastening bolt 3 is provided with an external thread, the first limiting plate 11 and the second limiting plate 12 arranged on the fastening bolt 3 are fixed by the external thread cooperating with a fastening nut provided with an internal thread. In other embodiments, the fastening bolt 3 includes a double-headed screw passing through both ends of the mounting hole 13 and a fastening nut threadedly connected to both ends of the double-headed screw, and a plurality of first limiting plates 11 and a plurality of second limiting plates 12 passing through the double-headed screw are fixed by the fastening nuts at both ends.
[0035] Specifically, Figure 4The first limiting piece 11 includes a first substrate 111 and a first positioning column 21 and a second positioning column 22 located at the edge of the first substrate 111 and extending outward, and a groove 23 is formed between the first positioning column 21 and the second positioning column 22. In a specific embodiment, the first positioning column 21 and the second positioning column 22 are symmetrically arranged with respect to the longitudinal center axis of the first substrate 111, and the first positioning column 21 and the second positioning column 22 are arranged in parallel and perpendicular to the edge of the first substrate 111. In other embodiments, the first positioning column 21 and the second positioning column 22 can also be arranged at other positions on the edge of the first substrate 111. Figure 5 The second limiting piece 12 includes a second substrate 121, and the first limiting piece 11 and the second limiting piece 12 are staggered and stacked with each other, that is, a second limiting piece 12 is arranged between every two first limiting pieces 11. Since the second limiting piece 12 only includes the second substrate 121, a gap is formed between the first positioning column 21 and the second positioning column 22 arranged on one first limiting piece 11 and the first positioning column 21 and the second positioning column 22 arranged on another first limiting piece 11, and the gap distance is equal to the thickness of the second limiting piece 12 (the thickness of the first positioning column 21 and the second positioning column 22 is consistent with the thickness of the first substrate 111). Therefore, when a plurality of first limiting pieces 11 and a plurality of second limiting pieces 12 are staggered and stacked with each other, a plurality of first positioning columns 21 are arranged at equal intervals, and a plurality of second positioning columns 22 are also distributed at equal intervals with the same intervals.
[0036] As another implementation, Figure 6 , Figure 7As shown, the first limiting piece 11 includes a first substrate 111 forming the base 10 and a first positioning column 21 forming the processing assembly 20, and the second limiting piece 12 includes a second substrate 121 forming the base 10 and a second positioning column 22 forming the processing assembly 20. The first limiting piece 11 and the second limiting piece 12 are symmetrical to each other (the positioning holes are not set at symmetrical positions in the figure. In actual use, the positioning holes can be set to be left-right symmetrical, so that the first limiting piece 11 and the second limiting piece 12 are symmetrical to each other), that is, the first positioning column 21 is set on the first substrate 1 11 (the direction in the figure, the actual direction is determined by the placement position of the processing mold) edge, and is perpendicular to the upper edge of the first substrate 111, the second positioning column 22 is set on the upper edge of the second substrate 121, and is perpendicular to the upper edge of the second substrate 121, the first substrate 111 of the first positioning column 21 and the second substrate 121 of the second positioning column 22 are set to the same structure, the position of the first positioning column 21 on the first substrate 111 and the position of the second positioning column 22 on the second substrate 121 are symmetrical about the longitudinal center axis of the substrates (first substrate 111 / second substrate 121). The cross-stacked first limiting plates 11 and the second limiting plates 12 are fixed and formed into a whole by tightening bolts 3. The thickness of the first limiting plates 11 is the same as that of the second limiting plates 12. Therefore, the first positioning columns 21 of the first limiting plates 11 and the second positioning columns 22 of the second limiting plates 12 respectively form a first positioning column 21 column and a second positioning column 22 column arranged at equal intervals. The first positioning column 21 column and the second positioning column 22 column are staggered, that is, the first positioning column 21 is opposite to the gap between the second positioning column 22, and the second positioning column 22 is opposite to the gap between the first positioning column 21, so that the columnar wire is conveniently wound in an "S" shape along the first positioning column 21 and the second positioning column 22 when in use.
[0037] Specifically, the first limiting plate 11 and the second limiting plate 12 are metal plates of the same thickness and are an integrally formed structure. A groove 23 is formed between the first positioning columns 21 and the second positioning columns 22 , and a plurality of spacer plates 2 are arranged in the groove 23 .
[0038] When in use, the microchannel fin heat exchanger processing mold is placed forward (the base 10 is at the bottom and the processing tool is at the top), and a spacer 2 is first placed in the groove 23, and the columnar wire is wound along the first positioning column 21 and the second positioning column 22 and passes through each positioning column (the first positioning column 21 / the second positioning column 22). After completing one winding, a columnar wire with a continuous S-shaped bend is formed, and then the spacer 2 is placed above the columnar wire and a second winding is performed on the spacer 2, and so on. Finally, a microchannel fin heat exchanger module is formed. The microchannel fin heat exchanger module produced by the microchannel fin heat exchanger processing mold of this embodiment has the advantages of high heat exchange efficiency, good drainage performance and low cost.
[0039] In summary, the microchannel fin heat exchanger processing mold of the present embodiment quickly forms a microchannel fin heat exchanger module by winding aluminum wire in an S shape between the first positioning column 21 and the second positioning column 22, thereby improving the efficiency of producing the microchannel fin heat exchanger; the processing tool is formed by a first limit plate 11 and a second limit plate 12 of a sheet structure cross-stacked with each other, which is convenient for assembling, adjusting the size and repairing the processing tool; by arranging a plurality of first positioning columns and a plurality of second positioning columns at equal intervals, the columnar wire distribution of the microchannel fin heat exchanger module produced by the mold is more uniform, the heat dissipation performance is better, and the module is neater and more beautiful.
