Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit cooling technology, specifically to a centralized spray cooling device for air conditioner outdoor units. Background Technology

[0002] Precision air conditioning refers to specialized air conditioning units designed for computer rooms, capable of fully meeting the environmental requirements of such rooms. Also known as constant temperature and humidity air conditioning, it is a relatively new type of unit that has gradually developed over the past 30 years. Compared to comfort air conditioners with the same cooling capacity, precision air conditioners have approximately twice the airflow volume, while their enthalpy difference is only half. Furthermore, precision air conditioners typically do not require dehumidification during operation. With a larger airflow volume, the unit operates above the air dew point, unlike comfort air conditioners which must cool the air below the dew point to cope with humidity loads. Therefore, the unit can improve its thermal efficiency by increasing the refrigerant evaporation temperature, thereby enhancing its operational economy. In existing technologies, prolonged operation in high-temperature weather, coupled with exposure to direct sunlight, leads to slow heat dissipation of the outdoor unit of the air conditioner, making it prone to shutdown. This, in turn, affects indoor cooling. In summer, when ambient temperatures are high (average temperature 30-35℃, and high temperatures can reach 40℃), the equipment frequently shuts down for protection purposes, affecting production.

[0003] Therefore, a centralized spray cooling device for air conditioner outdoor units is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a centralized spray cooling device for air conditioner outdoor units, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including an air conditioner outdoor unit, wherein a spraying mechanism is mounted on the back of the air conditioner outdoor unit; The spraying mechanism includes a fixed frame, a clamp, a connecting pipe, a spray pipe, a first flange, a second flange, a connector, a support frame, and a guide plate. The fixed frame is bolted to the back of the air conditioner outdoor unit. The clamp is fixedly connected to the back of the fixed frame. The connecting pipe is fixedly connected to the inner wall of the clamp. The spray pipe is fixedly connected to the bottom of the arc-shaped surface of the connecting pipe. The first flange is fixedly connected to the outer wall of the arc-shaped surface of the spray pipe. The upper surface of the second flange is bolted to the lower surface of the first flange. The outer wall of the arc-shaped surface of the connector is fixedly connected to the inner wall of the arc-shaped surface of the second flange. The lower surface of the support frame is fixedly connected to the outer wall of the arc-shaped surface of the connector. The guide plate is hinged to the inner wall of the support frame. A drive assembly for moving the guide plate is mounted on the back of the air conditioner outdoor unit.

[0006] Preferably, the drive assembly includes a connecting rod, a rotating rod, an impeller, and a drive rod. The connecting rod is fixedly connected to the inner wall of the arc-shaped surface of the connector, and the rotating rod is rotatably connected to the lower surface of the connecting rod via a bearing.

[0007] Preferably, the impeller is fixedly connected to the outer wall of the arc-shaped surface of the rotating rod, the drive rod is fixedly connected to the lower surface of the impeller, and the connecting member is internally equipped with a limiting component for improving the stability of the impeller.

[0008] Preferably, a hemisphere is fixedly connected to the lower surface of the drive rod to improve the smoothness of sliding with the guide plate.

[0009] Preferably, the limiting component includes a slide rail and a slider, the slide rail being formed on the inner wall of the arc-shaped surface of the connector, and the slider being slidably connected to the inner wall of the slide rail.

[0010] Preferably, there are three impellers, and the three sliders are respectively fixedly connected to the outer wall of the arc-shaped surface of the impeller.

[0011] Preferably, there are six connecting pipes in total, and a water collection tray is placed at the bottom of the outdoor unit of the air conditioner.

[0012] Compared with the prior art, this utility model provides a centralized spray cooling device for air conditioner outdoor units, which has the following beneficial effects: 1. When the outdoor unit of an air conditioner is working in high temperatures, the temperature of its heat dissipation fins will rise. Water sprayed through the spray pipes sprays water onto the outer wall and back fins of the outdoor unit. The drive component moves the guide plate up and down, allowing the spray pipes to spray water onto different positions on the outer wall and back fins of the outdoor unit. Water absorbs a large amount of heat during evaporation because water has a large latent heat of vaporization. When water evaporates on the surface of the outdoor unit, it can effectively carry away the heat generated by the outdoor unit, thereby reducing the temperature of the outdoor unit and improving its heat dissipation efficiency.

[0013] Second, the water sprayed from the spray pipe can rinse the fins on the back of the air conditioner outdoor unit. During the long-term operation of the air conditioner outdoor unit, dust, dirt and other impurities will accumulate on the fins. These impurities will affect the heat dissipation performance of the fins. By spraying and rinsing, the dirt on the fins can be effectively removed and the heat dissipation performance of the fins can be restored.

[0014] Third, the water collection tray placed at the bottom of the air conditioner outdoor unit can collect the water sprayed from the spray pipe. This collected water can be used for purposes such as flushing toilets, realizing the reuse of water resources. In areas where water resources are relatively scarce, it can effectively save water and has great environmental significance. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Example See Figures 1-6 This embodiment provides a centralized spray cooling device for air conditioner outdoor units, including an air conditioner outdoor unit 1, and a spray mechanism 2 is mounted on the back of the air conditioner outdoor unit 1; The spray mechanism 2 includes a fixed frame 21, a clamp 22, a connecting pipe 23, a spray pipe 24, a first flange 25, a second flange 26, a connector 27, a support frame 28, and a guide plate 29. The fixed frame 21 is fixedly installed on the back of the air conditioner outdoor unit 1 by bolts. The clamp 22 is fixedly connected to the back of the fixed frame 21 by bolts. The connecting pipe 23 is fixedly connected to the inner wall of the clamp 22. The spray pipe 24 is fixedly connected to the bottom of the arc-shaped surface of the connecting pipe 23. The first flange 25 is fixedly connected to the outer wall of the arc-shaped surface of the spray pipe 24. The upper surface of the second flange 26 is fixedly connected to the lower surface of the first flange 25 by bolts. A sealing gasket is installed between the first flange 25 and the second flange 26. The outer wall of the arc-shaped surface of the connector 27 is fixedly connected to the inner wall of the arc-shaped surface of the second flange 26. The lower surface of the support frame 28 is fixedly connected to the outer wall of the arc-shaped surface of the connector 27. The guide plate 29 is hinged to the inner wall of the support frame 28. A drive assembly for moving the guide plate 29 is installed on the back of the air conditioner outdoor unit 1.

[0019] Connect the connecting pipe 23 to an external water source. Water from the source is pumped into the connecting pipe 23 by a water pump and a booster pump. The water inside the connecting pipe 23 is pressurized by the booster pump and sprayed out from the spray pipe 24. As the water flows, the guide plate 29 moves up and down through the drive assembly, raising the spray pipe 24 to spray and cool the outer wall of the air conditioner outdoor unit 1. At the same time, it can also wash the fins on the back of the air conditioner outdoor unit 1 and wash away the dirt on the fins. If the drive component is damaged, the bolts of the first flange 25 and the second flange 26 can be removed, the connecting piece 27 can be removed, and a new drive assembly can be installed.

[0020] The drive assembly includes a connecting rod 210, a rotating rod 211, an impeller 212, and a drive rod 213. The connecting rod 210 is fixedly connected to the inner wall of the arc-shaped surface of the connector 27, and the rotating rod 211 is rotatably connected to the lower surface of the connecting rod 210 through a bearing.

[0021] Impeller 212 is fixedly connected to the outer wall of the arc-shaped surface of rotating rod 211, drive rod 213 is fixedly connected to the lower surface of impeller 212, and limiting component for improving the stability of impeller 212 is installed inside connector 27.

[0022] A hemisphere is fixedly connected to the lower surface of the drive rod 213 to improve the smoothness of sliding with the guide plate 29.

[0023] The water flow drives the impeller 212 to rotate, which in turn drives the rotating rod 211 to rotate. As the impeller 212 rotates, it drives the drive rod 213 to rotate, which in turn drives the hemisphere to rotate. When the drive rod 213 rotates to the bottom, the guide plate 29 will be perpendicular to the ground due to gravity. At this time, the water will spray onto the bottom of the outdoor unit 1. When the drive rod 213 drives the hemisphere to contact the guide plate 29, it will squeeze the guide plate 29, causing the guide plate 29 to rotate clockwise around the hinge point. At this time, the guide plate 29 does not guide the water flow, but the water flow can spray and rinse the high part of the back of the outdoor unit 1.

[0024] The limiting component includes a slide rail 214 and a slider 215. The slide rail 214 is formed on the inner wall of the arc-shaped surface of the connector 27, and the slider 215 is slidably connected to the inner wall of the slide rail 214.

[0025] When the impeller 212 rotates, it drives the slider 215 to slide inside the slide rail 214, thereby improving the stability of the impeller 212 during rotation.

[0026] There are three impellers 212, and three sliders 215 are fixedly connected to the outer wall of the arc-shaped surface of the impeller 212. The three impellers 212 can drive the drive rod 213 to rotate without generating much resistance to the water flow.

[0027] There are six connecting pipes 23 in total. A water tray 3 is placed at the bottom of the outdoor unit 1. The six connecting pipes 23 completely cover the area of ​​the outdoor unit that needs to be cooled and rinsed. The water tray 3 can collect the water sprayed from the spray pipe 24, realizing resource reuse.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
