[0002] With the development of science and technology, environmental and energy issues are becoming increasingly prominent, making energy conservation and emission reduction imperative. Evaporative cooling technology has received widespread attention due to its high economic efficiency, energy saving, environmental friendliness, and ability to improve air quality.

[0003] When the evaporative cooler is working, air is drawn in from the bottom of the evaporative cooler and passes through the gaps in the horizontally arranged heat transfer tube bundles. Some dust in the air will remain on the surface of the evaporative cooler, which will cause the performance of the evaporative cooler to degrade. Therefore, in order to ensure the cooling performance of the evaporative cooler, it is necessary to clean the evaporative cooler regularly.

[0004] Currently, cleaning evaporative coolers is mainly done manually, which makes it difficult to effectively clean the inner heat transfer tube bundles and is time-consuming and labor-intensive. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing evaporative coolers are difficult to clean effectively during the cleaning process of the inner heat transfer tube bundles, which is time-consuming and labor-intensive.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, an evaporative cooler cleaning device includes a base plate 1, a fixed frame 2 installed on the top of the base plate 1, a support frame 3 installed at the rear end of the fixed frame 2, a cleaning mechanism installed inside the support frame 3, and a dust collection mechanism installed on the fixed frame 2.

[0022] The dust removal mechanism includes a mounting plate 4 installed inside the support frame 3. A horizontally arranged electric guide rail 5 is installed at the front end of the mounting plate 4. A lifting assembly is installed at the output end of the electric guide rail 5. A spray pipe 11 is detachably installed at the output end of the lifting assembly. Several through holes are opened on the surface of the spray pipe 11, and cleaning brushes 12 are installed on both sides of the spray pipe 11. The lifting assembly includes a column 6. A groove is opened on the front end face of the column 6. A motor 7 is installed on the top. A lead screw 8 is rotatably installed in the groove. The top of the lead screw 8 is connected to the output shaft of the motor 7. A mounting seat 9 is slidably connected to the front end of the column 6. A protrusion extending into the groove is provided on the inner side of the mounting seat 9. The lead screw 8 passes through and is threadedly connected to the protrusion. A positioning seat 10 is fixedly connected to the front end of the mounting seat 9. The spray pipe 11 has an L-shaped structure and is installed through the positioning seat 10. A threaded hole is opened on the side of the positioning seat 10, and a set bolt is installed in the threaded hole. The end of the set bolt abuts against the spray pipe 11.

[0023] Place the evaporator cooler to be cleaned on the base plate 1 and directly below the dust collection hood 14. Connect the spray pipe 14 to the liquid nitrogen supply tank through the conduit. Open the valve on the liquid nitrogen supply tank. The liquid nitrogen is sprayed onto the surface of the evaporator cooler through the through hole on the spray pipe 11. The low temperature of the liquid nitrogen causes the dust to solidify and peel off from the surface of the evaporator cooler. Use the cleaning brush 12 to scrub the surface of the evaporator cooler to improve the cleaning effect. The operation of the electric guide rail 5 causes the spray pipe 11 and the cleaning brush 12 to move horizontally. The motor 7 drives the lead screw 8 to rotate, causing the mounting base 9 to drive the positioning base 10, the spray pipe 11 and the cleaning brush 12 to move vertically, which can complete the cleaning of the surface of the evaporator cooler.

[0024] The dust collection mechanism includes a vacuum cleaner 13 mounted on the top of the fixed frame 2. The vacuum cleaner 13 is connected to a dust collection hood 14 via a hose. The dust collection hood 14 is movably mounted inside the fixed frame 2. The fixed frame 2 has symmetrically opened sliding grooves on both sides. Fixed blocks 15 are fixed to both ends of the dust collection hood 14. Threaded rods 16 that pass through the sliding grooves are fixed to the sides of the fixed blocks 15. Nuts are installed on the threaded rods 16. Limiting strips 17 are symmetrically fixed to the ends of the dust collection hood 14 on both sides of the fixed blocks 15. Limiting blocks 18 are fixed to the ends of the limiting strips 17. Limiting grooves are opened on the inner side of the limiting blocks 18, and the limiting blocks 18 are engaged with the outer side of the fixed frame 2 through the limiting grooves.

[0025] The height of the dust collection cover 14 can be adjusted by sliding it up and down along the slide groove and then tightening the nuts and bolts. When the vacuum cleaner 13 is working, an upward airflow is generated below the dust collection cover 14, and the dust that has been cleaned can follow the airflow and enter the dust collection chamber inside the vacuum cleaner 13 through the hose under the action of the dust collection cover 14.

[0026] In practical use, the evaporative cooler to be cleaned is placed on the base plate 1 and located directly below the dust collection hood 14. The dust collection hood 14 is adjusted to a suitable height. The operation of the electric guide rail 5 causes the spray nozzle 11 and cleaning brush 12 to move horizontally. The motor 7 drives the lead screw 8 to rotate, causing the mounting base 9 to drive the positioning base 10, spray nozzle 11 and cleaning brush 12 to move vertically. This allows the heat transfer tube bundle to be cleaned row by row. The cleaning brush 12 is used to scrub the surface of the heat transfer tube bundle, improving the cleaning effect. The vacuum cleaner 13 is turned on, allowing the cleaned dust to enter the dust collection chamber inside the vacuum cleaner 13 through the hose under the action of the dust collection hood 14.
