Technical Field
[0001] This utility model relates to the technical field of evaporative air cooler defrosting equipment, specifically an integrated evaporative air cooler defrosting device. Background Technology
[0002] Evaporative air coolers are widely used in many fields such as industrial production, commercial refrigeration, and daily life to achieve the function of cooling and temperature reduction. Evaporative air coolers send out cold air through fans to quickly reduce the ambient temperature and provide a comfortable low-temperature environment for various scenarios. However, in actual operation, evaporative air coolers face a tricky problem - frost formation.
[0003] Traditional defrosting methods for evaporative air coolers have many drawbacks. For example, some methods use manual defrosting, which not only consumes a lot of manpower and time, but also makes it difficult to guarantee the defrosting effect and achieve complete and timely removal of frost. Other methods use single heating defrosting, which can melt the frost to a certain extent, but the heating process may cause thermal damage to other components of the evaporative air cooler. At the same time, the energy consumption is high and the economy is poor. In addition, traditional defrosting devices are often complex in structure, with each component being independent of the others, making installation and maintenance difficult and increasing the overall cost of the equipment.
[0004] It is against this backdrop that an integrated defrosting device for evaporative air coolers was developed. This addresses the various shortcomings of traditional defrosting methods for evaporative air coolers, providing stronger support for their widespread application. Utility Model Content

[0030] Dustproof cartridges 2: Located at the front end of the fan casing 1, three are arranged in a row. The cooling fan 8 is installed inside. When the air cooler is running normally, the dustproof cartridges can prevent dust, debris and other objects from entering the fan, ensuring the normal operation of the cooling fan, and at the same time guiding the cool air to be blown out in an orderly manner.
[0031] Mounting block 3: Located on both sides of the rear surface of the fan housing 1, its main function is to securely install the air cooler in the required position and ensure that the equipment does not shift or shake during operation.

[0043] Scraper 15: Located in the center of the front surface of scraper 12, it works in conjunction with the inclined blade to enhance the scraping effect on the frost layer on the inner surface of the fan housing 1, ensuring thorough defrosting.
[0044] Instructions for use
[0045] During operation, when the air cooler is working normally, the cooling fan 8 operates inside the dustproof casing 2, sending out cool air to achieve the cooling function. However, in some low-temperature and high-humidity environments, frost is easily formed on the inner surface of the fan housing 1. This requires the defrosting component to function. The two drivers 9 inside the fan housing 1 start working, driving the screw 10 connected to them to rotate. Since the screw 10 is threadedly connected to the threaded hole in the center of the slider 14, and the slider 14 is slidably sleeved in the guide groove in the guide block 7, under the guidance of the guide block 7, the rotation of the screw 10 will cause the slider 14 to move linearly along the guide groove. Because the slider 14 is fixed around the outer end of the connecting plate 11, the connecting plate 11 will also move synchronously with the slider 14. The scraper 12 fixedly connected to the front surface of the connecting plate 11 moves with the slider 14. The movement of the scraper 12, along with the inclined blades on its front surface and the central scraper 15, effectively scrapes off the frost from the inner surface of the fan housing 1. The scraped frost falls into the frost collection box 13 fixedly connected to the lower end of the scraper 12, thus collecting the frost. At the same time, the warm air box 4 at the upper end of the fan housing 1 also participates in the defrosting process. Outside air enters through several air inlets 5 arranged on the front surface of the warm air box 4, is heated, and then blown out through several air outlets 6 arranged on the lower surface of the warm air box 4, heating the inside of the fan housing 1 to assist defrosting, accelerate the melting of frost, and improve defrosting efficiency. In this way, through the mechanical scraping of the defrosting components and the heating-assisted defrosting of the warm air box 4, the integrated evaporative air cooler defrosting device can operate efficiently and stably, ensuring that the evaporative air cooler can work normally in various environments.
