Description

Technical Field

[0001] This utility model relates to the field of air-cooled outdoor unit technology, specifically to an air-cooled outdoor unit for refrigeration engineering that is easy to install. Background Technology

[0002] The basic principle of refrigeration technology is to utilize the physical properties of refrigerants to absorb or release heat through phase changes (such as vaporization and liquefaction) under specific conditions. Common refrigeration methods include vapor compression refrigeration, absorption refrigeration, jet refrigeration, and adsorption refrigeration. In refrigeration engineering, air-cooled outdoor units are indispensable and important equipment. As the name suggests, air-cooled outdoor units are refrigeration devices that use air to cool the condenser. They use a fan to draw in air and blow it across the condenser, thereby carrying away the heat inside the condenser and achieving a cooling effect.

[0003] While existing air-cooled outdoor units offer numerous advantages during use, they still suffer from several drawbacks. The installation and removal of filters is not sufficiently robust. Air-cooled outdoor units require filters to protect the air vents, but prolonged exposure to the environment leads to the accumulation of foreign matter, necessitating regular disassembly and cleaning. However, the traditional screw-fixing method, with its multi-point installation and disassembly, results in low efficiency and makes filter installation inconvenient. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an easy-to-install air-cooled outdoor unit for refrigeration engineering.

[0005] The technical solution adopted by this utility model to solve its technical problem is a convenient air-cooled outdoor unit for refrigeration engineering, including a unit body, a connecting ring, and a linkage rod. Exhaust pipes are welded to both sides of the upper outer wall of the unit body. A bearing is embedded in one side of the inner wall of the exhaust pipe. A connecting ring is rotatably installed inside the bearing. A connecting pipe is welded to the upper outer wall of the connecting ring. A filter screen is placed on the upper outer wall of the connecting pipe. Fixing blocks are welded to both outer walls of the filter screen. Limiting holes are opened inside both the fixing blocks and the exhaust pipe. Slots are opened on both outer walls of the exhaust pipe. A linkage rod is installed inside the limiting holes. A linkage plate is welded to the outer wall of one end of the linkage rod. A magnet is embedded in the outer wall of the linkage plate.

[0006] By adopting the above technical solution, the filter screen can block the exhaust pipe, preventing foreign objects from falling into the exhaust pipe and protecting the internal components of the exhaust pipe. The staff can manually take the filter screen and place it on the upper end of the connecting pipe, and the fixing block enters the limiting block. The connecting ring and the connecting pipe are connected by bearings to ensure the stability and smoothness of the circumferential rotation position at the upper end of the exhaust pipe. The position of the boss can be adjusted, and the linkage rod can be pushed or retracted by the magnet and the linkage plate, so that the linkage rod is controlled to enter the limiting hole of the fixing block. This ensures that the filter screen is stably positioned at the upper end of the connecting pipe and the exhaust pipe, and the filter screen is controlled and fixed, ensuring that the filter screen is easy to install.

[0007] Specifically, the outer wall of the unit body is provided with equally spaced parallel air intake filter plates, and a base is welded to the lower outer wall of the unit body.

[0008] By adopting the above technical solution, the air inlet filter plate can further filter the air entering the unit body, reducing the impact of impurities on the unit body. At the same time, the base design not only increases the stability of the unit body, but also facilitates the installation and fixing of the unit body.

[0009] Specifically, an exhaust mechanism is provided on one side of the inner wall of the exhaust pipe. The exhaust mechanism consists of a support frame, an impeller, and a drive motor. The support frame is welded to the lower end of the inner wall of the exhaust pipe. The impeller is rotatably installed inside the support frame. The drive motor is installed on the lower outer wall of the support frame and is connected to the impeller.

[0010] By adopting the above technical solution, the exhaust mechanism realizes the forced exhaust function inside the unit body. This design can ensure that the unit body can have enough cooling air passing through during operation, thereby improving the heat dissipation effect of the unit body, ensuring the stable operation of the unit body, and the rotation of the connecting ring will not affect the impeller.

[0011] Specifically, the connecting pipe is located at the upper end of the exhaust pipe, and the inner and outer diameters of the connecting pipe and the exhaust pipe are the same.

[0012] By adopting the above technical solutions, the smoothness and sealing of the air duct during connection are ensured, wind resistance and air leakage are reduced, and the efficiency and stability of the air duct are improved.

[0013] Specifically, limit blocks are welded to the outer walls of both sides of the exhaust pipe, the limit blocks are located corresponding to the limit holes, and the limit blocks are located inside the limit blocks.

[0014] By adopting the above technical solution, the design of the limiting block ensures the stable position of the linkage rod within the limiting hole and facilitates the initial fixing position of the filter screen by the staff, preventing the linkage rod from shaking and falling off during the movement process, thereby ensuring the stability and reliability of the filter screen.

[0015] Specifically, buckles are installed on both sides of the outer wall of the connecting pipe, and the buckles are engaged with the slots.

[0016] By adopting the above technical solution, the buckle and slot make the connection between the connecting pipe and the exhaust pipe more secure and stable. Furthermore, by setting different slot positions, the rotation angle of the boss can be controlled to ensure the push-out and retraction stroke of the boss on the linkage rod, and to ensure the stability of the position control of the linkage rod.

[0017] Specifically, both sides of the outer wall of the connecting ring are welded with bosses, which are located at the lower end of the bearing and are in contact with the outer wall of the magnet.

[0018] By adopting the above technical solution, the magnetic force of the magnet ensures that the linkage plate and the boss are attracted to each other, and that the linkage plate is always located outside the boss. When the operator manually rotates the connecting ring, the linkage plate can be pushed or pulled back according to the arc surface of the boss, so that the linkage rod is controlled to enter the limiting hole of the fixing block, thereby realizing the controlled fixing of the filter screen. This changes the traditional screw connection method, and can fix multiple points at the same time, realizing the rapid fixing and disassembly of the filter screen, and improving the maintenance efficiency of the filter screen.

[0019] The beneficial effects of this utility model are:

[0020] (1) The air-cooled outdoor unit for refrigeration engineering described in this utility model ensures that the filter screen is located in a stable position at the upper end of the connecting pipe and the exhaust pipe, so that the filter screen is controlled and fixed, and the filter screen is easy to install.

[0021] (2) The air-cooled outdoor unit for refrigeration engineering described in this utility model is easy to install and achieves controlled fixing of the filter screen. It changes the traditional screw connection method and can fix multiple points at the same time, realizing the quick fixing and disassembly of the filter screen and improving the maintenance efficiency of the filter screen.

[0029] 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.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention discloses a convenient air-cooled outdoor unit for refrigeration engineering, comprising a unit body 1, a connecting ring 2, and a linkage rod 3. Exhaust pipes 11 are welded to both sides of the upper outer wall of the unit body 1. A bearing 15 is embedded in one side of the inner wall of the exhaust pipe 11. The connecting ring 2 is rotatably mounted inside the bearing 15. A connecting pipe 21 is welded to the upper outer wall of the connecting ring 2. A filter screen 22 is placed on the upper outer wall of the connecting pipe 21. Fixing blocks 23 are welded to both outer walls of the filter screen 22. Limiting holes 13 are opened inside both the fixing blocks 23 and the exhaust pipe 11. Slots 14 are opened on both outer walls of the exhaust pipe 11. A linkage rod 3 is installed inside the limiting holes 13. A linkage plate 31 is welded to the outer wall of one end of the linkage rod 3. A magnet 32 ​​is embedded in the outer wall of the linkage plate 31.

[0031] In use, the filter screen 22 can block the exhaust pipe 11, preventing foreign objects from falling into the exhaust pipe 11 and protecting the internal components of the exhaust pipe 11. The staff can manually take the filter screen 22 and place it on the upper end of the connecting pipe 21, and the fixing block 23 enters the limiting block 16. The connecting ring 2 and the connecting pipe 21 are connected by the bearing 15 to ensure the stability and smoothness of the circumferential rotation position at the upper end of the exhaust pipe 11. The position of the boss 25 can be adjusted, and the linkage rod 3 can be pushed or retracted by the magnet 32 ​​and the linkage plate 31, so that the linkage rod 3 is controlled to enter the limiting hole 13 of the fixing block. This ensures that the filter screen 22 is stably positioned at the upper end of the connecting pipe 21 and the exhaust pipe 11, and the filter screen 22 is controlled and fixed, ensuring that the filter screen 22 is easy to install.

[0032] For filtering gases, exemplarily, such as Figure 1As shown, the outer wall of the unit body 1 is provided with equally spaced parallel air intake filter plates 12, and a base is welded to the lower outer wall of the unit body 1.

[0033] When in use, the air inlet filter plate 12 can further filter the air entering the unit body 1, reducing the impact of impurities on the unit body 1. At the same time, the base design not only increases the stability of the unit body 1, but also facilitates the installation and fixing of the unit body 1.

[0034] To drive airflow, for example, such as Figure 2 As shown, an exhaust mechanism is provided on one side of the inner wall of the exhaust pipe 11. The exhaust mechanism consists of a support frame, an impeller and a drive motor. The support frame is welded to the lower end of the inner wall of the exhaust pipe 11. The impeller is rotatably installed inside the support frame. The drive motor is installed on the lower outer wall of the support frame and is connected to the impeller.

[0035] During use, the exhaust mechanism enables forced exhaust within the unit body 1. This design ensures that the unit body 1 has sufficient cooling airflow during operation, thereby improving the heat dissipation effect of the unit body 1, ensuring stable operation of the unit body 1, and the rotation of the connecting ring 2 will not affect the impeller.

[0036] For smooth airflow, for example, such as Figure 2 As shown, the connecting pipe 21 is located at the upper end of the exhaust pipe 11, and the inner and outer diameters of the connecting pipe 21 and the exhaust pipe 11 are the same.

[0037] During use, it ensures smooth connection and airtightness of the air duct, reduces air resistance and leakage, and improves the efficiency and stability of the air duct.

[0038] For the purpose of limiting, for example, such as Figure 5 As shown, limit blocks 16 are welded to the outer walls on both sides of the exhaust pipe 11. The limit blocks 16 are located in the corresponding positions of the limit holes 13 and are located inside the limit blocks 16.

[0039] During use, the design of the limiting block 16 ensures the stable position of the linkage rod 3 within the limiting hole 13, and facilitates the initial fixing position of the filter screen 22 by the staff, preventing the linkage rod 3 from shaking and falling off during the movement, thereby ensuring the stability and reliability of the filter screen 22.

[0040] To limit the rotation angle, for example, such as Figure 4 As shown, buckles 24 are installed on both outer walls of the connecting pipe 21, and the buckles 24 are engaged with the slots 14.

[0041] In use, the buckle 24 and the slot 14 make the connection between the connecting pipe 21 and the exhaust pipe 11 more secure and stable. By setting different positions of the slot 14, the rotation angle of the boss 25 can be controlled to ensure the extension and retraction stroke of the boss 25 on the linkage rod 3, and to ensure the stability of the position control of the linkage rod 3.

[0042] To drive movement, for example, such as Figure 4 As shown, bosses 25 are welded to both outer walls of the connecting ring 2. The bosses 25 are located at the lower end of the bearing 15 and are in contact with the outer wall of the magnet 32.

[0043] During use, the magnetic force of magnet 32 ​​ensures that the linkage plate 31 and the boss 25 are attracted to each other, ensuring that the linkage plate 31 is always located outside the boss 25. When the operator manually rotates the connecting ring 2, the linkage plate 31 can be pushed or pulled back according to the arc surface of the boss 25, so that the linkage rod 3 is controlled to enter the limiting hole 13 of the fixing block 23, thereby realizing the controlled fixation of the filter screen 22. This changes the traditional screw connection method and can fix multiple points at the same time, realizing the quick fixation and disassembly of the filter screen 22, and improving the maintenance efficiency of the filter screen 22.

[0044] When using this utility model, the staff manually places the filter screen 22 on the upper end of the connecting pipe 21 to ensure that the filter screen 22 and the connecting pipe 21 are tightly fitted. At this time, the fixing blocks 23 on both sides of the filter screen 22 will enter the interior of the limiting block 16 and be located outside the limiting hole 13 inside the exhaust pipe 11.

[0045] The operator manually rotates the connecting ring 2, and the bearing 15 ensures that the connecting ring 2 rotates in a circular position at the upper end of the exhaust pipe 11. The position of the connecting ring 2 is adjusted so that the boss 25 contacts the outer wall of the magnet 32. The linkage plate 31 is pushed or pulled back according to the arc surface of the boss 25. As the connecting ring 2 rotates, the boss 25 pushes the linkage plate 31, so that the linkage rod 3 is controlled to enter the limiting hole 13 of the fixing block 23. The magnetic force of the magnet 32 ​​will maintain the adsorption state between the linkage plate 31 and the boss 25, ensuring that the filter screen 22 is firmly fixed to the upper end of the connecting pipe 21 and the exhaust pipe 11.

[0046] When the power supply to the drive motor is turned on, the exhaust mechanism is started, and the airflow is smooth through the exhaust pipe 11 and the air inlet filter plate 12, and sufficient cooling air is ensured to pass through the unit body 1.

[0047] When the filter screen 22 needs to be cleaned or replaced, the operator manually rotates the connecting ring 2 to separate the boss 25 from the linkage plate 31, while keeping it in the position of the slot 14. This allows for control of different rotation angles of the connecting ring 2. Under the action of the magnet 32, the linkage plate 31 will drive the linkage rod 3 to exit from the limiting hole 13 of the fixing block 23, and the operator can easily remove the filter screen 22 from the upper end of the connecting tube 21.
