Description

Technical Field

[0001] This utility model belongs to the field of air cooler technology, and specifically relates to an air cooler that is easy to maintain. Background Technology

[0002] An air cooler is a device that uses ambient air as the cooling medium and achieves heat exchange between a hot fluid (such as steam, high-temperature gas, or liquid) and the air through forced convection, thereby completing the fluid cooling or condensation process. Air coolers play an indispensable role in industrial production, the energy sector, and special environmental applications. Its core working principle is as follows: the hot fluid flows inside the pipes, transferring heat to the air outside the pipes through the pipe walls and fins. The air, driven by a fan, is forced to flow, thus carrying away heat and lowering the temperature of the hot fluid. This process requires no additional cooling water, relying solely on ambient air, making it particularly suitable for areas with water scarcity or poor water quality.

[0003] However, in practical use, the installation and maintenance of air coolers present certain inconveniences. Specifically, air coolers are typically fixed to mounting plates with bolts, and the outer casing is also connected with screws. To ensure a secure connection, multiple screws are often required. However, during maintenance, these screws must be removed one by one before the outer casing can be disassembled to expose the internal electrical components for inspection. This design not only makes the disassembly and assembly process time-consuming and laborious, but also, if the screws are stripped, it further increases the difficulty of disassembly and assembly, thereby increasing the overall complexity and workload of maintenance.

[0021] 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.

[0022] Please see Figures 1-4The present invention provides the following technical solution: an air cooler that is easy to maintain, including a housing 1, a fan 2 installed inside the housing 1, a protective filter 3 installed at the front end of the housing 1, a cover 4 provided at the top of the housing 1, mating recesses 5 connected to both sides of the cover 4, rectangular blocks 6 connected to both sides of the housing 1, a guide rod 7 installed inside the rectangular block 6, a guide block 9 sleeved on the surface of the guide rod 7, a spring 8 sleeved on the surface of the guide rod 7, a lever 10 connected to the front end of the guide block 9, a clamping block 11 connected to the top end of the guide block 9, a plug-in rod 12 connected to the side wall of the clamping block 11, a first magnetic block 13 connected to one side of the plug-in rod 12, and a second magnetic block 14 connected to the top end of the rectangular block 6.

[0023] In practical use, the air cooler mainly consists of a casing 1, a fan 2, a protective filter 3, and a cover 4. The fan 2 circulates air, allowing it to exchange heat with the medium being cooled, such as hot fluids or heat-generating equipment, thereby removing heat and achieving the cooling purpose. The model of this air cooler is DD60.

[0024] Preferably, the spring 8 is located between the two guide blocks 9, and the spring 8 is connected to the guide blocks 9. The guide blocks 9 can be elastically telescopically connected to the guide rod 7 through the spring 8. The mating recess 5 can be elastically engaged with the rectangular block 6 through the clamping block 11, the plug rod 12, the guide block 9, the lever block 10, the spring 8, and the guide rod 7. The plug rod 12 can be magnetically connected to the second magnetic block 14 through the first magnetic block 13.

[0025] In practical use, during disassembly, the operator needs to pinch the two levers 10 and bring them closer together. As the levers 10 move, they will also bring the guide blocks 9 closer together. During this process, the approaching guide blocks 9 will apply pressure to the spring 8, causing it to contract. Then, the movement of the guide blocks 9 will further displace the clamping block 11, and the displacement of the clamping block 11 will pull the plug rod 12 to move as well. The movement of the plug rod 12 ultimately causes the first magnetic block 13 to separate from the second magnetic block 14. Subsequently, the plug rod 12 moves out of the mating hole of the mating recess 5, thereby releasing the connection with the mating recess 5. At this point, the mating recess 5 and the rectangular block 6 can be easily separated, making it easier for the operator to separate the cover 4 from the housing 1, exposing the electrical components inside the air cooler, greatly facilitating subsequent maintenance work and significantly improving maintenance efficiency.

[0026] During installation, the operator must hold the two levers 10 close together to align the mating recess 5 with the rectangular block 6. After alignment, release the levers 10; under the force of the spring 8, the insertion rod 12 will automatically insert into the mating hole of the mating recess 5. Subsequently, the first magnetic block 13 and the second magnetic block 14 will attract each other, thus firmly securing the cover 4 to the housing 1.

[0027] Preferably, a fixing block 15 is connected to the front surface of the housing 1, a threaded rod 16 is installed inside the fixing block 15, a threaded sleeve 17 is threadedly connected to the surface of the threaded rod 16, and a limiting block 18 is connected to the top of the threaded sleeve 17. The limiting block 18 can form a threaded drive with the threaded rod 16 through the threaded sleeve 17, and the limiting block 18 can be adapted to the mounting lug size of the protective filter 3. The protective filter 3 can be detachably and fixedly connected to the housing 1 through the limiting block 18.

[0028] In practical use, the operator rotates the threaded rod 16, causing it to rotate stably along the inner ring of the bearing. As the threaded rod 16 rotates, the threaded sleeve 17 moves along the threads on the surface of the threaded rod 16. Because the opening size of the threaded sleeve 17 matches that of the fixed block 15, the threaded sleeve 17 does not rotate with the threaded rod 16 during movement. Subsequently, the threaded sleeve 17 drives the limiting block 18 to move together. The movement of the limiting block 18 disengages from the mounting ear of the protective filter 3, thereby enabling convenient installation and removal of the protective filter 3. This design makes cleaning dust and impurities on the protective filter 3 simple and easy, effectively preventing the problem of airflow and cooling effect being affected by excessive dirt on the protective filter 3.

[0029] During installation, the operator must ensure that the protective filter 3 is tightly fitted to the front end of the housing 1. Then, rotate the threaded rod 16 to cause the threaded sleeve 17 to move the limiting block 18 closer to the mounting ear of the protective filter 3 until the limiting block 18 is securely connected to the mounting ear, thus completing the fixing of the protective filter 3.

[0030] Working principle: The air cooler uses a fan 2 to drive airflow, facilitating heat exchange between the air and the cooled medium, such as hot fluids or heat-generating equipment, thereby removing heat and achieving a cooling effect. When maintenance is required, the operator pinches the two levers 10 and brings them close together. As the levers 10 move, they cause the guide blocks 9 to also move closer together, applying pressure to the spring 8 and causing it to contract. Next, the movement of the guide blocks 9 further displaces the clamping block 11, which in turn pulls the plug rod 12 to move as well. The movement of the plug rod 12 eventually causes the first magnetic block 13 to separate from the second magnetic block 14, and then the plug rod 12 moves out of the mating hole of the mating recess 5, thus disengaging from the mating recess 5. At this point, the mating recess 5 and the rectangular block 6 can be easily separated, allowing the operator to easily separate the cover 4 from the housing 1 for subsequent maintenance.

[0031] If the protective filter 3 needs to be disassembled for cleaning, the operator needs to rotate the threaded rod 16 to make it rotate stably along the inner ring of the bearing. As the threaded rod 16 rotates, the threaded sleeve 17 will move along the threads on the surface of the threaded rod 16. Since the opening size of the threaded sleeve 17 is adapted to the fixed block 15, the threaded sleeve 17 will not rotate with the threaded rod 16 during the movement. Subsequently, the threaded sleeve 17 will drive the limiting block 18 to move together. The movement of the limiting block 18 will disengage from the mounting ear of the protective filter 3, thereby realizing convenient disassembly and assembly of the protective filter 3. This design makes cleaning dust and impurities on the protective filter 3 simple and easy, effectively avoiding the problem of air circulation and cooling effect being affected by the protective filter 3 being too dirty.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
