In particular, when cleaning both sides of the heat exchange fins, it is often necessary to manually flip the heat exchange fins to achieve cleaning on both sides, which is not only time-consuming and labor-intensive, but also easily causes scratches or deformation on the surface of the heat exchange fins, affecting their service life and heat exchange performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1-5The present invention provides a flipping mechanism for cleaning plate heat exchanger plates, comprising a flipping plate 1 and a drive box 2 installed at both ends of the flipping plate 1. The drive box 2 supports the flipping plate 1 and drives the flipping plate 1 to flip the heat exchanger plate body 3.

[0022] Specifically, the flip plate 1 includes a first side plate 11, a second side plate 12, and a limiting frame 13. The lower end of the first side plate 11 is provided with a discharge hole 111. The lower ends of the first side plate 11 and the second side plate 12 are connected by the limiting frame 13. The first side plate 11 and the second side plate 12 form a V-shaped flip groove. When cleaning, the heat exchange plate body 3 first comes into contact with the first side plate 11. As the flip plate 1 changes angle, the first side plate 11 moves in a vertical direction, and the second side plate 12 tends to be flat. The heat exchange plate body 3 flips under its own weight to come into contact with the second side plate 12. The flip plate 1 changes angle in the opposite direction, and the second side plate 12 tends to be vertical. The gravity of the heat exchange plate body 3 overcomes the friction and can slide out of the V-shaped flip groove through the discharge hole 111. During the time when the heat exchange plate body 3 is in contact with the first side plate 11 or the second side plate 12, different surfaces of the heat exchange plate body 3 are cleaned.

[0023] It should be noted that, in order to drain water and avoid wear on the surface of the heat exchanger body 3, the first side plate 11 and the second side plate 12 are both hollow structures to facilitate drainage. At the same time, the contact surfaces between the first side plate 11 and the second side plate 12 and the heat exchanger body 3 are provided with a smooth protective layer to play a role in shock absorption and scratch prevention.

[0024] More specifically, the limiting frame 13 includes a limiting plate 131 and a four-bar linkage 132. Both ends of the four-bar linkage 132 are provided with limiting plates 131. The limiting plates 131 are connected to the first side plate 11 and the second side plate 12, and are movably connected to the drive box 2. The drive box 2 has a movable groove 21 that matches the limiting plate 131. The limiting plate 131 rotates on the drive box 2 through the movable groove 21, and the four-bar linkage 132 is placed inside the drive box 2.

[0025] Furthermore, a drive motor 22 is provided on one side of the drive box 2. The output end of the drive motor 22 is fixedly connected to a drive shaft 23. The two ends of the drive shaft 23 are movably connected to the drive box 2 through bearings. A diagonal rod 231 is provided on the drive shaft 23. The diagonal rod 231 passes through the four-link rod 132. The diagonal rod 231 rotates under the drive of the drive motor 22. The two ends of the diagonal rod 231 rotate out of alignment. Through the misalignment of the two ends of the diagonal rod 231, the four-link rod 132 can be pushed to rotate back and forth, thereby realizing the back and forth swing of the first side plate 11 and the second side plate 12, and flipping the heat exchange plate body 3 in the V-shaped flipping groove.

[0026] Working process: The drive motor 22 drives the drive shaft 23 to rotate, which in turn causes the inclined rod 231 fixed on the drive shaft 23 to rotate. Since the two ends of the inclined rod 231 are misaligned, it can push the four-link rod 132 to swing back and forth during rotation, thereby driving the limit frame 13 and the first side plate 11 and the second side plate 12 connected to it to move synchronously. In the initial state, the first side plate 11 and the second side plate 12 form a V-shaped flip groove. The heat exchange plate body 3 is placed in the V-shaped groove and first adheres to the first side plate 11. With the flip mechanism As the action begins, the first side plate 11 gradually moves vertically, while the second side plate 12 tends to be horizontal. During this process, the surface of the first side plate 11 is cleaned. The heat exchanger body 3 flips under the action of gravity, slides down and adheres to the second side plate 12. At this time, the other side surface of the heat exchanger body 3 can be cleaned. Subsequently, the flipping plate 1 reverses its angle, the second side plate 12 tends to be vertical, and the heat exchanger body 3 overcomes friction due to gravity and slides out of the discharge hole 111 at the lower end of the first side plate 11 into the V-shaped flipping groove, completing the discharge process.
