[0015] Beneficial effects of the present invention:

[0016] The rotating scrapers and plates can scrape the heat exchange tubes, the joints between the heat exchange tubes and fins, and the joints between the fixed frame and the heat exchange tubes, thereby pre-cleaning the dust on the difficult-to-clean areas on the heat exchange tubes and fins, and avoiding the situation where the dead corners of the joints between the heat exchange tubes and fins are not cleaned properly.

[0017] The scraper blade is curved on both sides, so when the scraper blade moves to the concave or convex area of ​​the fin, the scraper blade will bend inward, rebound and be squeezed and deformed, so that the scraper blade is always in close contact with the fin, thereby ensuring that the scraper blade can also clean the dust when the fin is deformed, thereby ensuring its cleaning effect.

[0018] The fins are located in the annular grooves, and the hollow cylinder of the fins will not contact the fins at this time, thereby avoiding mutual wear. Since the scraper has the characteristics of bending and deformation, there is no need for additional operation on the scraper. The scraper can always be in close contact with the fins after moving, thereby ensuring the scraping effect of the scraper on dust while avoiding mutual wear between the hollow cylinder and the fins.

[0019] The parts of the hollow cylinder on both sides of the annular groove that contact the fins have different diameters. In the early stage, the side with a smaller diameter contacts the fins. When the fins are worn, the hollow cylinder is controlled to move so that the side with a larger diameter contacts the fins, thereby ensuring that the fins can still play a good heat exchange role after one wear, thereby extending their service life.

[0020] When the scraper and the protrusion 2 come into contact with each other, the scraper will be deformed, and because the fin is thin, the protrusion 2 will also cause the fin to deform and rebound under the squeezing of the scraper, causing the fin to be in a shaking state, and the shaking fins can shake off the newly attached dust, so that the heat exchanger body can also perform simple dust cleaning work during daily use, thereby reducing the amount of dust adhesion when cleaning work is not performed, thereby ensuring the heat exchange efficiency of the heat exchanger body.

[0033] The scraper 5 is provided with a plurality of powder discharge ports 5a, through which dust is discharged.

[0034] It also includes an electric movable plate 6; four electric movable plates 6 are slidably connected to the fixed frame 1a; each electric movable plate 6 is fixedly connected to the corresponding DD motor 2, and the electric movable plate 6 is connected to an external power supply; each hollow cylinder 3 and each fin 1c are provided with an annular groove 3a in the contact area.

[0035] The parts of the hollow cylinder 3 on both sides of the annular groove 3a that contact the fins 1c have different diameters, so that the hollow cylinder 3 can be moved left and right to ensure contact with the fins 1c.

[0036] The cleaning assembly includes an electric guide rail 111, a moving block 112, a fixed plate 113, a rubber rod 114, a brush 115 and a DD motor 116; the front and rear sides of the fixed frame 1a are fixedly connected to two left-right symmetrical electric guide rails 111; each electric guide rail 111 is slidably connected to a moving block 112; all the moving blocks 112 on the same side are fixedly connected to a fixed plate 113; each fixed plate 113 is rotatably connected to a plurality of rubber rods 114, and the rubber rods 114 on the front side are connected to the corresponding rubber rods 114 on the rear side. They are in contact with each other, each rubber rod 114 is provided with a plurality of bristles 115; each fixed plate 113 is provided with an air inlet hole 113a; each rubber rod 114 is provided with a connecting hole 114a, and each rubber rod 114 is also provided with a plurality of air suction holes 114b, and the connecting hole 114a is connected with the corresponding air inlet hole 113a; each fixed plate 113 is fixedly connected with a plurality of DD motors 116; each rotating part of the DD motor 116 is fixedly connected with the corresponding rubber rod 114; the DD motor 116 is connected with an external power supply.

[0037] It also includes a rubber plate 201 and a rubber strip 202; each fixing plate 113 is fixedly connected to four rubber plates 201; each rubber plate 201 is located between two adjacent rubber rods 114; a plurality of rubber strips 202 are fixedly connected to the left and right sides of the rubber plate 201; each rubber plate 201 is provided with a second connecting hole 201a; each rubber plate 201 is also provided with a plurality of second air suction holes 201b; the second air suction hole 201b is connected to the corresponding second connecting hole 201a, and the second connecting hole 201a is connected to the corresponding air inlet hole 113a.

[0038] The rubber plate 201 is in a T-shape, so that the second air suction hole 201b of the rubber plate 201 is away from the bristles 115, thereby preventing the bristles 115 from being inserted into the second air suction hole 201b.

[0039] The specific working steps are:

[0040] The air inlet 113a is connected to an external air intake device.

[0041] When cleaning, first control the DD motor 2 to drive the hollow cylinder 3, the scraper 4 and the scraper 5 to rotate counterclockwise from the left to the right, and the rotating scraper 4 and the scraper 5 can scrape the heat exchange tube 1b, the connection between the heat exchange tube 1b and the fin 1c, and the connection between the fixed frame 1a and the heat exchange tube 1b, so as to pre-clean the dust on the areas that are not easy to clean on the heat exchange tube 1b and the fin 1c, and avoid the situation that the dead corner of the connection between the heat exchange tube 1b and the fin 1c is not cleaned properly. Because the heat exchange tube 1b will directly exchange heat with the outside world, if a tube is directly put on the outer layer of the heat exchange tube 1b, and then the tube is driven to rotate for easy cleaning, the heat exchange efficiency of the heat exchange tube 1b will be reduced, and the hollow cylinder 3 is It is hollow and does not contact the heat exchange tube 1b. The heat exchange tube 1b is cleaned only by the scraper 4, which minimizes the impact on the heat exchange efficiency of the heat exchange tube 1b during cleaning. It should be noted that since the fin 1c is thin, the fin 1c is easily squeezed out and bent and deformed during transportation and installation, and the scraper 4 is curved on both sides, so that when the scraper 4 moves to the curved concave or convex area of ​​the fin 1c, the scraper 4 will bend inward and rebound and be squeezed and deformed, so that the scraper 4 is always in close contact with the fin 1c, thereby ensuring that the scraper 4 can also clean the dust when the fin 1c is deformed, thereby ensuring its cleaning effect, and when the scraper 5 is scraping, dust is likely to remain on the scraper 5, so some dust can be discharged through the powder discharge port 5a to avoid residue.

[0042] Considering that the heat exchange tube 1b needs to contact with the fin 1c through the hollow cylinder 3 so that the fin 1c can play a heat exchange role, but when cleaning, the hollow cylinder 3 and the fin 1c rotate in a contact state, which is easy to cause the hollow cylinder 3 and the fin 1c to wear each other, and then the hollow cylinder 3 and the fin 1c cannot be in close contact, thereby affecting the heat exchange effect. Therefore, before cleaning, the electric moving plate 6 will drive the DD motor 2, the hollow cylinder 3, the scraper 4 and the scraper 5 to move to the left, so that the fin 1c is located in the annular groove 3a, as shown in FIG. Figure 3 In the state shown, the hollow cylinder 3 will not contact the fin 1c, thereby avoiding mutual wear. Since the scraper blade 4 has the characteristic of bending and deformation, there is no need to perform additional operations on the scraper blade 4. The scraper blade 4 can always be in close contact with the fin 1c after moving, thereby ensuring the scraping effect of the scraper blade 4 on dust while avoiding mutual wear between the hollow cylinder 3 and the fin 1c.

[0043] It should be noted that, when cleaning the fins 1c, although the hollow cylinder 3 does not contact the fins 1c, which can avoid wear between the hollow cylinder 3 and the fins 1c during cleaning, when the heat exchanger body 1 is working normally, the hollow cylinder 3 needs to be in contact with the fins 1c for heat exchange. Therefore, after the cleaning work is completed, it is necessary to control the movement of the hollow cylinder 3 so that the hollow cylinder 3 and the fins 1c can be in contact with each other for heat exchange. In the process of the hollow cylinder 3 moving and contacting with the fins 1c, the hollow cylinder 3 and the fins 1c will still be damaged. Mutual extrusion and wear occur. Over time, the hollow cylinder 3 and the fin 1c cannot be in close contact, resulting in a poor heat exchange effect. Therefore, the diameters of the parts of the hollow cylinder 3 on both sides of the annular groove 3a that contact the fin 1c are different. In the early stage, the side with a smaller diameter contacts the fin 1c. When the fin 1c is worn, the hollow cylinder 3 is controlled to move so that the side with a larger diameter contacts the fin 1c, thereby ensuring that the fin 1c can still play a good heat exchange role after one wear, thereby extending its service life.

[0044] When the scraper 4 and the scraper 5 rotate to perform the scraping work, the electric guide rail 111 drives the moving block 112 to drive the fixed plate 113 and its related parts to descend, and at the same time, the DD motor 116 drives the rubber rod 114 and the bristles 115 to rotate, so that the rubber rod 114 and the bristles 115 move from top to bottom while cleaning the dust on the fin 1c, and the rubber rod 114 is deformed after contacting the heat exchange tube 1b, and continues to move downward to perform the cleaning work, and the rubber rod 114 returns to its original shape when passing over the heat exchange tube 1b. During cleaning, the external suction device will make the suction hole 114b have suction through the air inlet hole 113a and the connecting hole 114a, thereby sucking away the floating dust, and the bristles 115 are made of rubber, which will generate static electricity when in contact with the fins 1c during cleaning, and then have a certain adsorption capacity for dust, thereby preventing the dust from being lifted up and attached to the heat exchanger body 1 again. By cleaning the dust attached to the heat exchange tube 1b and the fin 1c, the heat exchange efficiency of the heat exchanger body 1 is prevented from being reduced, thereby achieving the energy-saving function.

[0045] Although the rubber bristles 115 have a certain adsorption capacity for dust when cleaning, their adsorption capacity will be weakened when too much dust is attached, and the dust will be knocked off when it comes into contact with the bristles 115, so the bristles 115 will collide with the rubber strip 202 when rotating, and then knock off the dust attached to the bristles 115, and the external suction device will suck away the knocked-off dust through the air inlet hole 113a, the connecting hole 201a and the suction hole 201b, thereby cleaning the dust on the bristles 115, avoiding the dust from floating again and attaching to the heat exchanger body 1 again after a large amount of dust is attached to the bristles 115 when the bristles 115 are cleaning, and avoiding the bristles 115 The cleaning ability will be greatly reduced when a large amount of dust is attached to the bristles 115.

[0046] Example 2

[0047] On the basis of Example 1, Figure 3 and Figure 5 As shown, it also includes a protrusion 101; the heat exchange tube 1b is fixedly connected to a plurality of protrusions 101 distributed at equal distances.

[0048] It also includes a second protrusion 102; each fin 1c is fixedly connected to a second protrusion 102 on the left front part and the right rear part, and the relatively distributed second protrusions 102 can cause the fin 1c to deform and vibrate to the maximum extent when being squeezed.

[0049] Each scraper blade 4 is provided with a notch 4a to prevent a certain area from being unable to perform scraping work.

[0050] The specific working steps are:

[0051] The scraper 5 will contact with the bump 101 when rotating to scrape off the dust. Since the scraper 5 is provided with a powder discharge port 5a, the scraper 5 will be partially deformed into an arc shape when contacting the bump 101. The dust located at the angle between the scraper 5 and the heat exchange tube 1b will stay beside the bump 101, and the deformed scraper 5 will shake when rebounding over the bump 101, thereby shaking off the attached dust, thereby reducing the residual dust on the scraper 5. Since the bump 101 is located on the upper part of the heat exchange tube 1b, the bristles 115 can directly clean the dust beside the bump 101 during cleaning.

[0052] The heat exchanger body 1 will be cleaned only when a large amount of dust is attached to it. In the process of gradually accumulating dust, the heat exchange effect of the heat exchanger body 1 will gradually decrease. Therefore, after each use of the heat exchanger body 1, the electric moving plate 6 drives the hollow cylinder 3 to move to the left, and then the DD motor 2 drives the hollow cylinder 3, the scraper 4 and the scraper 5 to rotate, so that the scraper 5 scrapes away the dust attached to the heat exchange tube 1b, and the scraper 4 will contact the protrusion 2 102 during rotation. When the scraper 4 and the protrusion 2 102 are in contact with each other, the scraper 4 will be deformed. Since the fin 1c is relatively thin, the protrusion 2 102 will also cause the fin 1c to deform and rebound under the squeezing of the scraper 4, so that the fin 1c is in a shaking state. The shaking fin 1c can shake off the newly attached dust, so that the heat exchanger body 1 can also be simply cleaned during daily use, thereby reducing the amount of dust attached when cleaning is not performed, thereby ensuring the heat exchange efficiency of the heat exchanger body 1.

[0053] It should be noted that, since the second protrusions 102 on the same fin 1c are relatively distributed, when the second protrusions 102 are squeezed, the front and rear parts of the fin 1c are squeezed in opposite directions, which can cause the fin 1c to deform and vibrate to the maximum extent.

[0054] It should be noted that the fin 1c is in a shaking state during cleaning, which is conducive to the bristles 115 to clean the dust attached to the fin 1c.

[0055] The scraper 4 is deformed when it contacts the protrusion 102, and the scraper 4 will not fit with the fin 1c when it is deformed, which will cause the dust in part of the fin 1c to not be cleaned. Therefore, a notch 4a is provided on the other side of the scraper 4, so that when the other side of the scraper 4 passes through the protrusion 102, the protrusion 102 can pass through the notch 4a, so that the uncleaned dust in the area on the other side of the scraper 4 is scraped off to avoid residue. When cleaning, some of the fallen dust can easily enter the scraper 4, and some dust will also enter the scraper 4 at normal times. Therefore, the scraper 4 can shake off the attached dust by vibration when rotating, and then discharge it from the notch 4a, thereby avoiding a large amount of dust adhering to the scraper 4 and preventing some dust from remaining on the fin 1c when the scraper 4 is cleaning.

[0056] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
