Abstract
Description
Technical Field
[0001] The utility model relates to the field of heat exchange, in particular to a fin screening device. Background Art
[0002] The overall width of the heat exchanger is fixed, that is, the fins in the heat exchanger are set on the heat exchange tubes of fixed length. When the fin spacing is set differently, the number of fins should also be changed accordingly. The fins are provided with a single-sided flange. Ideally, the fins are set on the heat exchange tubes in the same direction. Due to the support of the flange, the main body of the fins can achieve an equidistant arrangement effect and be heated evenly.
[0003] However, in the prior art, when manufacturing a heat exchanger, it cannot be ensured that the fins remain in the same direction during the transmission process. As a result, when the fins are mounted on the heat exchange tubes, the bodies of adjacent non-directional fins will stick together, affecting the heating state of the fins. Therefore, it is necessary to rely on manual sorting of the directions of the fins, which consumes manpower and affects the accuracy. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a fin screening device in order to overcome the defect of the prior art that the directions of the fins need to be sorted manually.

[0050] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0051] Example 1
[0052] like Figure 1-Figure 3 As shown, this embodiment provides a fin screening device, which includes a base 1 and a screening part 2. The base 1 includes a conveying part. The conveying part can drive the fins 101 located on the upper surface of the base 1 to move relative to the screening part 2, so that the fins 101 in a direction opposite to the preset direction can be screened out when they move to the screening part 2, without manual sorting. There is at least one accommodating unit space 102 for accommodating the fins 101 above the conveying part. The screening part 2 is located above the base 1. There is a gap between the screening part 2 and the base 1. The height H of the gap is less than the thickness T of the thickest part of the accommodating unit space 102, and greater than the thickness t of the thinnest part of the accommodating unit space 102, so that the fins 101 in different directions can be stuck in front of the screening part 2 by adapting the gap of the fins 101, and the fins 101 in the same direction as the preset direction can pass through the screening part 2.
[0053] In this embodiment, the screening part 2 is connected to the base 1, so that the height of the gap can be kept stable, thereby stably screening out the fins 101 in directions different from or the same as the preset direction. Of course, in other embodiments, the screening part 2 can also be fixed independently.
[0054] In this embodiment, the preset direction of the fin 101 is with the flange facing upward. When the flange of the fin 101 faces upward, the fin 101 can be transferred to the next position through the screening part 2; and when the flange of the fin 101 faces downward, the fin 101 will be stuck in front of the screening part 2.
[0055] In this embodiment, by setting the accommodation unit space 102 as a virtual definition, the screening effect of the gap on the fin 101 can be further ensured. Of course, in other embodiments, the accommodation unit space 102 can also be set as a solid structure that fits the outline of the fin 101 and is surrounded.
[0056] In this embodiment, by setting the screening part 2 as a needle-shaped part, the tip of the screening part 2 corresponds to the accommodating unit space 102, and the fins 101 can be screened with a relatively simple structure.
[0057] Example 2
[0058] like Figure 4-Figure 8 As shown, the overall structure of the fin screening device of this embodiment is basically the same as that of the embodiment 1, except that:
[0059] In this embodiment, by setting the screening part 2 as a plate-shaped member, the fins 101 can be screened with a relatively simple structure.
[0060] In this embodiment, the fin screening device also includes a push rod 3; the base 1 also includes a first through hole 11, and the push rod 3 can be movably inserted into the first through hole 11. When the push rod 3 penetrates into the first through hole 11, the fin 101 stuck in front of the screening part 2 can be pushed up, so that the fin 101 can be flipped around the side close to the screening part 2; the screening part 2 also includes a second through hole 21. When the fin 101 is pushed up by the push rod 3, the fin 101 can pass through the second through hole 21 and flip and fall on the base 1 behind the screening part 2. The second through hole 21 limits the fin 101 to avoid additional displacement or twisting of the fin 101 during the flipping process.
[0061] In this embodiment, the fin 101 can be further limited during the flipping process by setting the shape of the second through hole 21 to correspond to the fin 101. Of course, in other embodiments, the second through hole 21 can be set to any shape that allows the fin 101 to pass through, such as a rectangle.
[0062] In this embodiment, the fin screening device further includes a control unit (not shown in the figure) and a detection unit (not shown in the figure). The control unit, the detection unit, and the push rod 3 are electrically connected. When the detection unit detects that the fin 101 is stuck in front of the screening unit 2, the control unit can control the push rod 3 to penetrate the first through hole 11, so that the automatic flipping of the fin 101 in the opposite direction can be realized, further saving manpower. The electrical connection and control method of the control unit, the detection unit, and the push rod 3 are all prior arts.
[0063] In this embodiment, by setting the base 1 to be inclined toward the rear of the screening part 2, the fin 101 can be pushed to a position perpendicular to the base 1 by the push rod 3 and can be flipped over and fall onto the base 1 behind the screening part 2 under the action of gravity without further action of the push rod 3.
[0064] In this embodiment, by setting the angle α between the screening portion 2 and the base 1 to 90°, the fin 101 can be limited when flipping under the action of gravity, further avoiding additional displacement or twisting of the fin 101 during the flipping process.
[0065] In this embodiment, the fin screening device also includes a fence 4, which is connected to the upper surface of the base 1. The two fences 4 correspond to the two sides of the base 1 respectively, and the two fences 4 clamp the fin 101 in the center. When the fin 101 undergoes relative displacement with the screening part 2, the fin 101 can be limited.
[0066] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
