[0018] The following will further elaborate on the present utility model in combination with the embodiments given in the accompanying drawings.
[0019] Referring to Figures 1 - 6 As shown, a fin forming die device of this embodiment includes an upper die 1 and a lower die 2. Both the upper die 1 and the lower die 2 are arranged on a fin forming machine. The upper die 1 is located above the lower die 2. The upper die 1 and the lower die 2 are divided into a slotted area and a folding area. The slotted area is located at the feeding end of the aluminum coil, and the folding area is located at the discharging end. The upper die 1 has an accommodating groove 11, and the lower die 2 has an opening protrusion 21. The opening protrusion 21 corresponds to the position of the accommodating groove 11. The upper side of the opening protrusion 21 has an inclined guiding part 22, and the accommodating groove 11 has a guiding groove 12 that cooperates with the guiding part 22.
[0020] Through the above technical solution, the folding area punches and folds the fins. The same as a common fin forming machine, this application will not elaborate further. Before folding, heat dissipation holes are punched in the aluminum coil first, and then folding is carried out, so that heat dissipation holes with air guiding parts can be punched. The air guiding parts have a guiding effect, which improves the flow rate of the air flow, and further improves the heat dissipation effect of the produced fins.
[0021] Specifically, the guiding part 22 and the guiding groove 12 punch out a wind guiding part on the aluminum coil, which not only guides the air flow but also expands the contact area between the air flow and the fins, further improving the heat dissipation effect of the fins.
[0022] As a specific embodiment of the improvement, the opening protrusion 21 is divided into a first protrusion 31 and a second protrusion 32, the accommodating groove 11 is divided into a first groove 41 and a second groove 42, the first protrusion 31 corresponds to the first groove 41, the second protrusion 32 corresponds to the second groove 42, and the guiding parts 22 on the first protrusion 31 and the second protrusion 32 face in opposite directions.
[0023] Through the above technical solution, the first protrusion 31 cooperates with the first groove 41, and the second protrusion 32 cooperates with the second groove 42. When stamping, two heat dissipation holes in opposite directions are processed, so that the air flow on both sides of the fins can smoothly pass through and take away heat. When installing the fins, there is no need to adjust the direction, and the installation efficiency is high.
[0024] As a specific embodiment of the improvement, the first protrusions 31 are arranged at intervals in one row, the second protrusions 32 are arranged at intervals in another row, and the row where the first protrusions 31 are arranged is adjacent to the row where the second protrusions 32 are arranged.
[0025] Through the above technical solution, the first protrusion 31 and the second protrusion 32 respectively punch out heat dissipation holes in two adjacent quadrants of the fin. Each corrugated fin is the same, which can provide a good heat dissipation effect.
[0026] Specifically, the heat dissipation holes guide the air flow to pass through multiple fins for heat dissipation, and the heat dissipation effect is better.
[0027] As a specific embodiment of the improvement, the first protrusion 31 and the second protrusion 32 are arranged at intervals in the width direction.
[0028] Through the above technical solution, the first protrusion 31 and the second protrusion 32 are arranged at intervals in the width direction, so that the width of the flow channel between the adjacent fins formed by stamping is large, the air flow passes smoothly, and thus the heat dissipation effect is improved.
[0029] As a specific embodiment of the improvement, one side of the opening protrusion 21 is an opening part 5, and the edge adjacent to the opening part 5 is arranged in an arc shape.
[0030] Through the above technical solution, the edge adjacent to the opening part 5 is arranged in an arc shape, and there is an arc-shaped groove in the accommodating groove 11 that cooperates with it, which improves the stability during the production process, avoids cracking at this position, and the arc-shaped guiding effect is good, the contact area is larger, and further improves the heat dissipation performance of the fins.
[0031] Specifically, the opening parts 5 of the adjacent first protrusion 31 and second protrusion 32 are in the same plane.
[0032] Specifically, the air flow leaving the heat dissipation holes enters the next heat dissipation hole on the opposite side under the guidance of the air guiding part corresponding to the next heat dissipation hole in this quadrant and the air guiding part on the opposite side. The contact area between the air flow and the fins is large, and the heat dissipation effect is better. Moreover, the fins do not need to be adjusted in direction during installation, and the installation efficiency is high.
[0033] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and retouches made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
