Description

Technical Field

[0001] This utility model relates to the field of evaporative air coolers, and in particular to an evaporative air cooler that is easy to maintain. Background Technology

[0002] Evaporative air coolers are widely used cooling devices in industrial fields. They utilize the principle of water evaporation and heat absorption to achieve efficient cooling of air or fluids. Their structure typically includes a fan, heat exchange tube bundle, spray system, and fresh air inlet. The fresh air inlet is the key channel for external air to enter the equipment, while the fresh air inlet protective net is used to prevent dust, debris, and other contaminants from entering the equipment, ensuring heat exchange efficiency and long-term stable operation. The main function of the fresh air inlet protective net is to prevent foreign objects from entering the evaporative air cooler, avoiding blockage of the heat exchange tube bundle or damage to core components such as the fan. However, due to long-term exposure to the external environment, the protective net easily accumulates pollutants such as dust, leaves, and insects. These pollutants not only reduce the equipment's ventilation efficiency but may also cause corrosion or bacterial growth, thus affecting the equipment's performance and lifespan. Therefore, regular cleaning and maintenance of the fresh air inlet protective net is a necessary measure to ensure the efficient operation of the evaporative air cooler.

[0003] In traditional evaporative air coolers, the fresh air inlet protective mesh is typically fixed to the fresh air inlet of the equipment with multiple bolts. While this fixing method is structurally simple, it has significant shortcomings in actual maintenance. When cleaning or replacing the protective mesh is required, maintenance personnel must use tools to disassemble each fixing bolt individually, a cumbersome and time-consuming operation that increases the difficulty and workload of maintenance. These problems make cleaning and maintaining traditional fresh air inlet protective meshes quite troublesome. Therefore, there is an urgent need for an evaporative air cooler that is easy to maintain to solve these problems. Utility Model Content

[0004] The main objective of this invention is to provide an evaporative air cooler that is easy to maintain, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-maintain evaporative air cooler includes an evaporative air cooler with a limiting component fixedly installed at one end. The limiting component consists of a fixed U-shaped frame, a fixed spring, and connecting plates. The fixed spring is fixedly installed on the inner wall of the fixed U-shaped frame. Two connecting plates are symmetrically fixedly installed at the inner end of the fixed U-shaped frame. A movable connecting component is slidably installed on the fixed U-shaped frame. The movable connecting component consists of a movable U-shaped frame and connecting shafts. Four connecting shafts are symmetrically fixedly installed at the upper and lower ends of the movable U-shaped frame. An air inlet protective net is installed inside the evaporative air cooler, and the air inlet protective net is rotatably installed on the connecting shafts.

[0007] Preferably, the evaporative air cooler has multiple fresh air inlets.

[0008] Preferably, the limiting component is located between two adjacent fresh air inlets, and the connecting fixing plate is fixedly installed at one end of the evaporative air cooler by bolts.

[0009] Preferably, two mounting slots are symmetrically formed on one side wall of the movable U-shaped frame on the movable connecting assembly. The movable U-shaped frame is slidably mounted on the fixed U-shaped frame through the two mounting slots, and the movable U-shaped frame is located inside the fixed spring.

[0010] Preferably, the air inlet protective net consists of a protective net body, an L-shaped connecting frame, and an installation sleeve. There are two L-shaped connecting frames that are symmetrically fixedly installed at the outer end of the protective net body. There are two installation sleeves that are respectively fixedly installed at one end of the two L-shaped connecting frames. The installation sleeves are rotatably installed on the connecting shaft. The protective net body is movably installed inside the fresh air inlet opened on the evaporative air cooler.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By installing a limiting component on the evaporative air cooler and a movable connecting component on the limiting component, the air inlet protective net can be rotatably installed on the movable connecting component. When removing the air inlet protective net from the fresh air inlet, no tools are needed; it can be done by hand, and the disassembly process is relatively simple and convenient, thus facilitating the cleaning and maintenance of the air inlet protective net. At the same time, the combination of the limiting component and the movable connecting component makes it easy and convenient to install the air inlet protective net into the fresh air inlet, thereby reducing the workload of staff and improving work efficiency.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 As shown, an easy-to-maintain evaporative air cooler includes an evaporative air cooler 1. A limiting component 2 is fixedly installed at one end of the evaporative air cooler 1. The limiting component 2 consists of a fixed U-shaped frame 6, a fixed spring 7, and connecting fixing plates 8. The fixed spring 7 is fixedly installed on the inner wall of the fixed U-shaped frame 6. Two connecting fixing plates 8 are symmetrically fixedly installed at the inner end of the fixed U-shaped frame 6. A movable connecting component 3 is slidably installed on the fixed U-shaped frame 6. The movable connecting component 3 consists of a movable U-shaped frame 9 and connecting shafts 11. Four connecting shafts 11 are symmetrically fixedly installed at the upper and lower ends of the movable U-shaped frame 9. An air inlet protective net 4 is installed inside the evaporative air cooler 1. The air inlet protective net 4 is rotatably installed on the connecting shafts 11. Multiple fresh air inlets 5 are opened on the evaporative air cooler 1. When it is necessary to clean and maintain the air inlet protective net 4, the movable connecting component 3 is pulled by hand away from the evaporative air cooler 1. The movable U-shaped bracket 9 is moved on the upper part of the air inlet. At this time, the movable U-shaped bracket 9 will compress the fixed spring 7 on the limiting component 2. At the same time, the movable connecting component 3 will drive the air inlet protective net 4 to move. After the air inlet protective net 4 moves out of the fresh air inlet 5, the air inlet protective net 4 will be rotated outward about the connecting shaft 11. Then, the movable U-shaped bracket 9 can be released to clean and maintain the air inlet protective net 4 with water or compressed air. After the air inlet protective net 4 is cleaned and maintained, the movable U-shaped bracket 9 is pulled to compress the fixed spring 7. Then, the air inlet protective net 4 will be rotated inward about the connecting shaft 11. When the air inlet protective net 4 is parallel to the evaporative air cooler 1, the movable U-shaped bracket 9 is released. At this time, under the elastic force of the fixed spring 7, the movable connecting component 3 and the air inlet protective net 4 will move towards the evaporative air cooler 1 until the air inlet protective net 4 is embedded in the fresh air inlet 5.

[0020] Specifically, the limiting component 2 is located between two adjacent fresh air inlets 5. The connecting fixing plate 8 is fixedly installed at one end of the evaporative air cooler 1 by bolts. Two mounting slots 10 are symmetrically opened on one side wall of the movable U-shaped frame 9 on the movable connecting component 3. The movable U-shaped frame 9 is slidably installed on the fixed U-shaped frame 6 through the two mounting slots 10, and the movable U-shaped frame 9 is also located inside the fixed spring 7. The air inlet protective net 4 consists of a protective net body 12, an L-shaped connecting frame 13, and a mounting sleeve 14. There are two L-shaped connecting frames 13, which are symmetrically fixedly installed at the outer end of the protective net body 12. There are two mounting sleeves 14, which are respectively fixedly installed at one end of the two L-shaped connecting frames 13. The mounting sleeves 14 are rotatably installed on the connecting shaft 11. The protective net body 12 is movably installed on the fresh air inlet of the evaporative air cooler 1. Inside the inlet 5, the protective net body 12, L-shaped connecting bracket 13, and mounting sleeve 14 on the air inlet protective net 4 can rotate around the connecting shaft 11. The size design of the protective net body 12 is adapted to the fresh air inlet 5. When the protective net body 12 is embedded in the fresh air inlet 5, the edge of the protective net body 12 is tightly fitted with the inner wall of the fresh air inlet 5, which restricts the rotation of the protective net body 12 around the connecting shaft 11. At the same time, the thickness of the protective net body 12 and the depth of the fresh air inlet 5 are also precisely designed to ensure that after the protective net body 12 is embedded in the fresh air inlet 5, its outer surface is flush with or slightly lower than the outer wall of the evaporative air cooler 1, further ensuring that the protective net body 12 will not easily rotate due to external force and is stably installed inside the fresh air inlet 5, effectively blocking dust, debris, etc. from entering the interior of the evaporative air cooler 1.

[0021] Finally, by setting a limiting component 2 on the evaporative air cooler 1 and a movable connecting component 3 on the limiting component 2, the air inlet protective net 4 is rotatably installed on the movable connecting component 3. When removing the air inlet protective net 4 from the fresh air inlet 5, no tools are needed; it can be done by hand, and the removal process is relatively simple and convenient, thus facilitating the cleaning and maintenance of the air inlet protective net 4. At the same time, the cooperation between the limiting component 2 and the movable connecting component 3 makes it relatively simple and convenient to install the air inlet protective net 4 into the fresh air inlet 5, thereby reducing the workload of staff and improving work efficiency.
