Description

Technical Field

[0001] This utility model relates to the field of atomizing cooling equipment for air conditioner outdoor units, specifically a highly available atomizing cooling system. Background Technology

[0002] In environments such as computer rooms and laboratories where ambient temperature control is crucial, precision air conditioning is typically used. Computer rooms and laboratories often operate continuously for extended periods, sometimes exceeding a year, requiring indoor temperature fluctuations to remain within acceptable limits throughout this timeframe.

[0003] During this period, precision air conditioners experience high outdoor temperatures in summer. These high temperatures reduce the temperature difference between the working fluid inside the outdoor condenser of the direct-expansion precision air conditioner and the outdoor air, resulting in insufficient heat dissipation from the condenser. This leads to an increase in compressor outlet pressure. When the compressor's high-pressure switch reaches its limit pressure, the high-pressure switch protection trips, causing the compressor to stop working and the precision air conditioning system to cease cooling. This poses a significant threat to the safe operation of the data center. With the increasing frequency of extreme high temperatures in summer, and given that water mist devices are typically located near the outdoor condenser of the precision air conditioner in harsh working environments, device malfunctions are frequent during extreme heat.

[0004] Therefore, how to ensure the cooling of the fins of precision air conditioners during the high temperatures of summer, thereby ensuring the control and regulation capabilities of precision air conditioners for the indoor environment, has become an urgent problem to be solved in the field of air conditioner outdoor unit atomization cooling equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies where the heat dissipation efficiency of the air conditioner outdoor unit decreases due to the high outdoor temperature during long-term operation. This invention provides a highly available atomized cooling system. By setting up a spray host and a backup host that can be switched or used simultaneously, the spray nozzles can continuously spray and cool the fins of the air conditioner outdoor unit, thereby ensuring the safe operation of the air conditioner outdoor unit.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] A highly available atomizing cooling system includes several spray nozzles, each of which is connected to a spray host and / or a backup host. Valves are provided between the spray nozzles and the spray host, and between the spray nozzles and the backup host.

[0008] The spray nozzle can be connected to the main spray unit or the backup main unit via the valve;

[0009] Both the main spray unit and the backup spray unit are connected to a water supply system.

[0010] Currently, precision air conditioning typically employs two methods for cooling: external spray systems and condensate circulation cooling. Essentially, both methods involve direct heat exchange with the fins of the outdoor unit to cool them. By ensuring the outdoor unit's fins don't overheat for extended periods, air conditioner failure can be prevented, thus guaranteeing high availability for extended periods. High availability means minimizing system downtime through design; in this invention, it means reducing the time the outdoor unit's fins cannot be cooled.

[0011] In existing technologies, when the cooling of the fins of an air conditioner outdoor unit is achieved through an external spray system, the high availability of the external spray system is required to ensure the cooling needs of the outdoor unit due to the reliability requirements of continuous operation. However, since the external ambient temperature is always high when the outdoor unit needs to be cooled, the probability of failure of the existing external spray system will increase significantly under long-term operation. When the external spray system fails, the cooling of the outdoor unit will fail, resulting in the loss of the air conditioning control capability.

[0012] When the fins of an air conditioner's outdoor unit are cooled by condensate, the condensate needs to come into contact with the fins to achieve heat exchange. Therefore, it is necessary to pump the condensate onto the fins or build water pipes to form heat exchange. This not only greatly increases operating costs, but also requires equipment that can work continuously for long periods of time to continuously cool the fins, from the production of condensate to the pumping process. There is also a risk of failure in high-temperature environments, which may lead to the failure of the air conditioning's control capabilities.

[0013] This invention uses spray cooling of air conditioner outdoor unit fins as its basis. By setting up a main spray unit and a backup spray unit, the spray nozzle is equipped with at least two water supply paths. This ensures that the spray nozzle can effectively maintain its spraying capacity during long-term operation, achieving the purpose of cooling the air conditioner outdoor unit fins. The spray nozzle can be connected to the main spray unit or the backup spray unit through the valve. Therefore, the spray source of the spray nozzle in this invention can be switched by controlling the valve. The spray nozzle can be supplied by the main spray unit, the backup spray unit, or both the main spray unit and the backup spray unit simultaneously. This ensures that the spray nozzle can maintain its supply even when the main spray unit fails, the backup spray unit fails, or both the main spray unit and the backup spray unit experience partial failures. This greatly improves the availability of the spray nozzle during operation and ensures that it can maintain its spraying state during long-term operation.

[0014] In this invention, both the main spray unit and the backup main unit are connected to a water supply system. Therefore, when the water supply in the main spray unit is insufficient, the backup main unit can be switched to provide water supply assistance, or a backup main unit can be added directly to increase the water supply capacity. This avoids a decrease in spray volume due to insufficient water supply, thereby ensuring the continuous operation of the spray nozzles and preventing the outdoor unit of the air conditioner from overheating.

[0015] This invention, through the design of several spray nozzles, avoids the imbalance in cooling capacity of the air conditioner outdoor unit fins caused by nozzle damage. Furthermore, by setting up two main units—a spray host and a backup host—it can ensure that the spray host and backup host operate simultaneously or switch flexibly during long-term operation. This ensures that the invention can continuously cool the air conditioner outdoor unit fins even in high-temperature environments without cooling failure due to overheating of the main unit or spray supply issues. Therefore, this invention provides highly available atomized cooling for the air conditioner outdoor unit fins.

[0016] Furthermore, the spray nozzle includes a main body base, which is connected to the spray host and / or the backup host;

[0017] A nozzle support base is provided on the main body base, and a connecting pipe is provided between the nozzle support base and the main body base. One end of the connecting pipe is connected to the nozzle support base, and the other end is connected to the main body base.

[0018] A lifting track is fixed on the nozzle support base, and a lifting sliding base is embedded in the lifting track. The lifting sliding base can slide freely along the lifting track. A water-air mixing base is fixed on the lifting sliding base, and a high-pressure nozzle is fixed on the water-air mixing base. The water-air mixing base is connected to the connecting pipe, and the high-pressure nozzle is connected to the water-air mixing base.

[0019] In this invention, the spray nozzle is connected to a spray supply pipe via a main base, thereby connecting to the main spray unit and / or a backup main unit to continuously supply water mist to the high-pressure nozzle. The nozzle support base is used to support the weight, and the connecting pipe is made of rigid material, which can both transport water mist and bear weight. A lifting track on the nozzle support base is used to mount the lifting sliding base, which is used to mount the water-air mixing base. The water-air mixing base is used to install and support the high-pressure nozzle, and the high-pressure nozzle can be connected to the connecting pipe through the water-air mixing base, so that the high-pressure nozzle can mix part of the air and obtain water mist through the water-air mixing base.

[0020] The lifting track and the lifting sliding base are used to adjust the height of the high-pressure nozzle to adapt to the position of the fins. The water-air mixing base is used to draw in air and mix it with water mist before delivering it into the high-pressure nozzle. The high-pressure nozzle is used to spray mist onto the fins.

[0021] Furthermore, the top of the lifting track is provided with an end limiting component, which is used to prevent the lifting sliding base from detaching from the lifting track.

[0022] In this invention, the end limiting component is located at the top of the lifting track, thereby preventing the lifting sliding base from detaching from the lifting track with the high-pressure nozzle and losing its height adjustment capability.

[0023] Furthermore, the end limiting assembly includes a limiting end head, a telescopic rod is fixed below the limiting end head, a limiting spring is sleeved on the telescopic rod, one end of the telescopic rod is fixed to the limiting end head, and a collision plate is fixed to the other end of the telescopic rod.

[0024] In this utility model, the limiting end serves as a fixed support for the end limiting assembly. The extension and retraction of the telescopic rod, in conjunction with the limiting spring, buffers the impact of the lifting sliding base. The collision plate is used to increase the contact area, thereby allowing the buffering capacity of the limiting spring to be fully released.

[0025] Furthermore, the top of the lifting track is provided with an extension end, and a wind direction and speed detector is fixed on the extension end. The main body base is rotatably connected to the connecting pipe, and a drive mechanism for driving the connecting pipe to rotate is provided inside the main body base. The connecting pipe is fixedly connected to the nozzle support base.

[0026] In this invention, the extended end is used to extend the height of the wind direction and speed detector, thereby preventing the spray from the high-pressure nozzle from affecting the wind direction and speed detection results. The wind direction and speed detector in this invention adopts the wind direction instrument installation device and wind direction detection component disclosed in the prior art (CN211728931U), thus ensuring the effectiveness of the wind direction and speed detection results of this invention. In high-temperature environments, even with wind force, it is difficult to meet the heat dissipation requirements of the air conditioner outdoor unit fins, so it is necessary to continuously supply water mist to the fins to achieve the purpose of cooling. However, when the actual wind direction and speed are detected, the nozzle bearing base can be rotated in time by adjusting the connecting pipe of the main base, thereby realizing the angle rotation of the high-pressure nozzle and preventing the water mist from the high-pressure nozzle from not being sprayed on the fins.

[0027] Furthermore, the main body base includes a water-guiding layer, and a steering layer is fixed below the water-guiding layer. The water-guiding layer is used to connect the connecting pipe, and the end of the connecting pipe extends into the steering layer. The steering layer is used to drive the connecting pipe to rotate.

[0028] In this invention, the water-guiding layer is used to connect to an external water mist delivery pipe, thereby effectively ensuring the water mist supply. The turning layer is independent of the water-guiding layer. The turning layer is connected to the end of the connecting pipe, thereby driving the rotation of the connecting pipe within the turning layer, avoiding mutual interference between the rotation driving process and the water mist delivery process.

[0029] Furthermore, the water-guiding layer includes a water-guiding shell, the connecting pipe extends into the water-guiding layer, a connecting end is fixed to the side of the connecting pipe, a corrugated pipe is connected to the connecting end, one end of the corrugated pipe is connected to the connecting end, and the other end is connected to the water-guiding pipe.

[0030] A return spring is provided on the side of the connecting pipe. One end of the return spring is fixed to the connecting pipe, and the other end is fixed to the inner wall of the water inlet shell.

[0031] The steering layer includes a steering housing, an adjusting gear is provided inside the steering housing, the adjusting gear is fixed to the end of the connecting pipe, a drive gear is provided on the side of the adjusting gear, the drive gear meshes with the adjusting gear, a drive motor is connected to the shaft of the drive gear, and the drive motor is fixed to the steering housing.

[0032] In this invention, the water-guiding shell is used to protect the water-guiding layer. After the connecting pipe extends into the water-guiding layer, it communicates with the corrugated pipe through the connecting end. The corrugated pipe can twist or extend, so that it can follow the connecting end when it rotates, avoiding the connection state between the connecting end and the water-guiding pipe being affected by the rotation of the connecting pipe. The return spring can restore the original position of the connecting pipe by its own elasticity in the natural state, thereby resetting the high-pressure nozzle.

[0033] The steering housing protects the steering layer. The adjusting gear is directly fixed to the end of the connecting pipe. When the adjusting gear rotates, the connecting pipe also rotates synchronously. Therefore, the driving gear drives the adjusting gear to rotate, which in turn drives the connecting pipe to rotate. The driving gear is driven by the driving motor. When the driving motor is in working condition, it maintains the driving force on the driving gear and can maintain the position of the driving gear. When the driving motor is in a neutral state, the driving gear loses external force. Under the action of the return spring, the connecting pipe can drive the adjusting gear and the driving gear to rotate and return to their original positions.

[0034] Furthermore, the nozzle support base includes a connecting part, the upper part of which is fixed to the lifting rail, a reinforcing rib is fixed on the connecting part, the bottom of the reinforcing rib is fixed to the connecting part, and the side of the reinforcing rib is fixed to the lifting rail;

[0035] A support portion is fixed below the connecting portion, the support portion is fixed to the connecting pipe, and the connecting pipe passes through the support portion and the connecting portion and communicates with the water-air mixing base;

[0036] The lifting track includes a support plate, which is perpendicular to and fixedly connected to the connecting part. A guide rail is fixed on the support plate, and the axis of the guide rail is perpendicular to the connecting part.

[0037] In this utility model, the connecting part of the nozzle support base is used to connect with the lifting rail. In order to ensure the stability of the lifting rail, a reinforcing rib is provided on the lifting rail for reinforcement. The reinforcing rib can effectively improve the anti-tipping ability of the lifting rail on the connecting part. The support part is used to bear the weight and drive all the components above it to rotate synchronously when the connecting pipe rotates.

[0038] The lifting track supports the weight of the entire track through the bearing plate, and the plate as the main load-bearing body can effectively avoid shear stress damage, thereby improving the service life of this utility model. The guide rail is used to guide and limit the trajectory of the lifting sliding base.

[0039] Furthermore, the water-air mixing base includes an outer frame, which is fixed to the lifting and sliding base. A mixing chamber is fixed inside the outer frame, and a plurality of air inlet ducts are provided inside the mixing chamber. The air inlet ducts extend outside the mixing chamber to form air inlets.

[0040] The mixing chamber and the high-pressure nozzle are connected.

[0041] In this invention, the outer frame of the water-air mixing base is used to protect and can be fixed to the lifting sliding base so as to follow the position movement of the lifting sliding base. The water-air mixing base and the connecting pipe can be connected by a hose or telescopic pipe, so as to avoid the change of position of the water-air mixing base from affecting the water mist supply.

[0042] The air inlet duct is used to connect to the outside world, and the mixing chamber is used to draw in air from the air inlet duct and mix it with water mist. After the air is drawn in, it is mixed with water mist and supplied to the high-pressure nozzle.

[0043] Furthermore, the connecting pipe is fitted with an anti-tipping cone, and the anti-tipping cone is filled with solid material.

[0044] The connecting pipe is rotatably connected to the anti-tipping cone via a bearing.

[0045] In this invention, to ensure the stability of the connecting pipe, an anti-tipping cone is installed on the outer sleeve of the connecting pipe, and the solid-filled anti-tipping cone provides lateral support for the connecting pipe. The connecting pipe and the anti-tipping cone are rotatably connected by bearings, which can effectively improve the flexibility of the connecting pipe and avoid excessive pulling or squeezing of the connecting pipe by the anti-tipping cone. Thus, the flexibility of the connecting pipe can be maintained while protecting its stability.

[0046] In summary, this utility model has the following advantages compared with the prior art:

[0047] (1) By designing several spray nozzles, this utility model can avoid the imbalance in cooling capacity of the air conditioner outdoor unit fins caused by damage to the spray nozzles. By setting up two main equipment sets, the spray host and the backup host, it can ensure that the spray host and the backup host work simultaneously or switch flexibly during long-term operation. This ensures that this utility model can continuously cool the air conditioner outdoor unit fins in high-temperature environments without cooling failure due to overheating of the main equipment or cooling failure due to spray supply problems. This allows this utility model to provide highly available atomized cooling for the air conditioner outdoor unit fins.

[0048] (2) In this utility model, the water-guiding shell is used to protect the water-guiding layer. After the connecting pipe extends into the water-guiding layer, it is connected to the corrugated pipe through the connecting end. The corrugated pipe can twist or extend, so that it can follow the connecting end when the connecting end rotates, so as to avoid the connection state between the connecting end and the water-guiding pipe being affected by the rotation of the connecting pipe. The reset spring can restore the original position of the connecting pipe by its own elasticity in the natural state, so that the high-pressure nozzle is reset.

[0049] (3) In this utility model, in order to ensure the stability of the connecting pipe, an anti-tipping cone is installed on the outer sleeve of the connecting pipe, and the solid-filled anti-tipping cone provides lateral support for the connecting pipe. The connecting pipe and the anti-tipping cone are connected by a bearing to effectively improve the flexibility of the connecting pipe and avoid the anti-tipping cone from causing excessive pulling or squeezing of the connecting pipe, thereby maintaining the flexibility of the connecting pipe while protecting its stability.

[0056] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0057] Example:

[0058] like Figures 1-4As shown, this embodiment relates to a high-availability atomizing cooling system, including a plurality of spray nozzles A, each of which is connected to a spray host C and / or a backup host D. Valves B are provided between the spray nozzles A and the spray host C, and between the spray nozzles A and the backup host D.

[0059] The spray nozzle A can be connected to the spray host C or the backup host D through the valve B;

[0060] Both the main spray unit C and the backup main spray unit D are connected to a water supply system.

[0061] This embodiment is actually applied to the spray cooling operation of the outdoor unit fins of an air conditioner in a high-temperature environment. When maintaining the precision air conditioner to work continuously for a long time, it is necessary to continuously cool the fins of the outdoor unit in order to avoid the air conditioner's ability to regulate temperature failing due to excessively high fin temperatures in a high-temperature environment.

[0062] In this embodiment, maintaining the high availability of the spray nozzle A is crucial to ensuring the high availability of the cooling effect on the fins. In actual operation, multiple spray nozzles A are used to prevent the loss of continuous cooling due to the malfunction of some nozzles A.

[0063] In addition, it is necessary to ensure that the water mist supply of the spray nozzle A is sufficient to ensure that the spray nozzle A can continuously spray and cool the fins. However, relying solely on the spray host C for water mist supply carries the risk of spray host C failure. Therefore, in this embodiment, a backup host D is set up on the basis of the spray host C to avoid cooling failure caused by the failure of the spray host C.

[0064] Based on this, there are also significant hidden dangers in the water supply problem in high-temperature environments. Therefore, in this embodiment, both the spray host C and the backup host D are connected to the water supply system. In this embodiment, the spray host C and the backup host D can be connected to the same water supply system or to different water supply systems.

[0065] When the backup host D and the spray host C are connected to the same water supply system, the water supply capacity can be reduced due to problems such as scale during long-term operation. When the water supply capacity of the spray host C decreases, the spray supply can be ensured by turning on the backup host D and using the backup host D to supply spray together. The pipeline can also be maintained by periodically switching between the spray host C and the backup host D, thereby avoiding a reduction in the spray supply.

[0066] When the backup host D and the spray host C are connected to different water supply systems, they can switch to the other water supply system in time if there is a problem with one of the water supply systems, so as to avoid water supply problems. When the water pressure is low, the spray supply can also be guaranteed by the dual system water supply.

[0067] The water supply system in this embodiment is an external water supply system, which adopts the existing technology of water supply, such as internal water supply in the factory or tap water supply, etc. This embodiment does not involve any improvement to the water supply system.

[0068] In this embodiment, both the spray host C and the backup host D are existing devices used to produce water mist. The specific models are selected based on actual work requirements to facilitate large-scale procurement, thereby enabling this embodiment to be mass-produced.

[0069] In this embodiment, valve B is a ball valve or butterfly valve, which can be purchased on a large scale in the existing technology. It can ensure the sealing performance in the closed state and the smooth flow in the open state, thereby enabling this embodiment to be mass-produced.

[0070] Furthermore, the spray nozzle A includes a main body base 9, which is connected to the spray host C and / or the backup host D;

[0071] A nozzle support base is provided on the main body base 9, and a connecting pipe 10 is provided between the nozzle support base and the main body base 9. One end of the connecting pipe 10 is connected to the nozzle support base, and the other end is connected to the main body base 9.

[0072] A lifting rail 2 is fixed on the nozzle support base. A lifting sliding base 5 is embedded in the lifting rail 2. The lifting sliding base 5 can slide freely along the lifting rail 2. A water-air mixing base 4 is fixed on the lifting sliding base 5. A high-pressure nozzle 3 is fixed on the water-air mixing base 4. The water-air mixing base 4 is connected to the connecting pipe 10. The high-pressure nozzle 3 is connected to the water-air mixing base 4.

[0073] In practical applications, the main body base 9 is used to support the overall spray nozzle A and connect the spray host C and / or the backup host D. The nozzle support base is used to support the lifting rail 2 and the components mounted on the lifting rail 2.

[0074] When it is necessary to adjust the high-pressure nozzle 3 to align with the fins of the air conditioner outdoor unit, the position of the lifting sliding base 5 is adjusted so that it can slide on the lifting track 2, thereby driving the water-air mixing base 4 and the high-pressure nozzle 3 to slide, thus adjusting the height of the high-pressure nozzle 3 so that it can align with the fins. The sliding of the lifting sliding base 5 can be achieved by a motor and rollers. Because the lifting sliding base 5 is embedded in the lifting track 2, it is only necessary to install a motor on the lifting sliding base 5 and cooperate with rollers to drive the lifting sliding base 5 to slide on the lifting track 2. Alternatively, a winch can be used to pull and the lifting sliding base 5 can be slid by its own weight to adjust the height of the lifting sliding base 5 on the lifting track 2. In this embodiment, the power supply for driving the lifting sliding base 5 to slide on the lifting track 2 is provided by existing technology, thereby ensuring the stability of the lifting sliding base 5 sliding on the lifting track 2.

[0075] Furthermore, the top of the lifting track 2 is provided with an end limiting component 1, which is used to prevent the lifting sliding base 5 from dislodging from the lifting track 2.

[0076] Furthermore, the end limiting component 1 includes a limiting end 12, a telescopic rod 14 is fixed below the limiting end 12, a limiting spring 13 is sleeved on the telescopic rod 14, one end of the telescopic rod 14 is fixed to the limiting end 12, and a collision plate 15 is fixed to the other end.

[0077] Furthermore, the top end of the lifting track 2 is provided with an extension end 11, and a wind direction and wind speed detector 16 is fixed on the extension end 11. The main body base 9 is rotatably connected to the connecting pipe 10. The main body base 9 is provided with a driving mechanism for driving the connecting pipe 10 to rotate. The connecting pipe 10 is fixedly connected to the nozzle support base.

[0078] In this embodiment, the end limiting component 1 can restrict the lifting sliding base 5 within the lifting track 2, thereby preventing the lifting sliding base 5 from coming out of the lifting track 2. The extension end 11 is used to extend the position of the wind direction and wind speed monitor, thereby preventing the water mist sprayed by the high-pressure nozzle 3 from affecting the detection of wind direction and wind speed.

[0079] In this embodiment, the detection of wind direction and speed is achieved through existing technology. The purpose is to obtain the detection results of wind direction and speed. After obtaining the detection results of wind direction and speed, the height of the lifting sliding base 5 can be adjusted by manual or electric start to spray onto the fins based on the wind direction and speed.

[0080] Furthermore, the main body base 9 includes a water-guiding layer 91, and a steering layer 92 is fixed below the water-guiding layer 91. The water-guiding layer 91 is used to connect the connecting pipe 10, and the end of the connecting pipe 10 extends into the steering layer 92. The steering layer 92 is used to drive the connecting pipe 10 to rotate.

[0081] Furthermore, the water-guiding layer 91 includes a water-guiding shell 911, the connecting pipe 10 extends into the water-guiding layer 91, a connecting end 913 is fixed on the side of the connecting pipe 10, a corrugated pipe 914 is connected to the connecting end 913, one end of the corrugated pipe 914 is connected to the connecting end 913, and the other end is connected to the water-guiding pipe 915.

[0082] A return spring 912 is provided on the side of the connecting pipe 10. One end of the return spring 912 is fixed to the connecting pipe 10, and the other end is fixed to the inner wall of the water inlet shell 911.

[0083] The steering layer 92 includes a steering housing 923, inside which is an adjusting gear 924. The adjusting gear 924 is fixed to the end of the connecting pipe 10. A drive gear 921 is provided on the side of the adjusting gear 924. The drive gear 921 meshes with the adjusting gear 924. A drive motor 922 is connected to the shaft of the drive gear 921. The drive motor 922 is fixed to the steering housing 923.

[0084] Furthermore, the connecting pipe 10 is fitted with an anti-tipping cone 101, and the anti-tipping cone 101 is filled with solid material.

[0085] The connecting pipe 10 and the anti-tipping cone 101 are rotatably connected by bearings.

[0086] After measuring the wind direction and speed, the factors affecting the water mist effect on the fins include not only the height of the high-pressure nozzle 3, but also the spraying angle of the high-pressure nozzle 3. In this embodiment, by setting the main body base 9 as a water-guiding layer 91 and a deflecting layer 92, both the water-guiding requirements of the water mist and the angle adjustment requirements of the high-pressure nozzle 3 can be met.

[0087] When it is necessary to adjust the angle of the high-pressure nozzle 3 or to adaptively adjust the angle of the high-pressure nozzle 3 according to the wind speed and direction detection results, the steering layer 92 will drive the nozzle support base and all the components mounted on the nozzle support base to turn by rotating the connecting pipe 10, that is, to turn the high-pressure nozzle 3.

[0088] In this embodiment, the water mist delivery of the connecting pipe 10 is achieved by connecting the connecting end 913 and the water inlet pipe 915 through the corrugated pipe 914. The water inlet pipe 915 is connected to the spray host C and / or the standby host D, thereby realizing the delivery of water mist. The corrugated pipe 914 can utilize its own extensibility and bendability to effectively connect the water inlet pipe 915 and the connecting end 913 when the connecting pipe 10 drives the connecting end 913 to rotate, thus avoiding the interruption of water mist delivery.

[0089] The return spring 912 continuously applies elastic restoring force to the outer wall of the connecting pipe 10. When the connecting pipe 10 rotates, the return spring 912 can provide elastic restoring force to the connecting pipe 10. When the drive motor 922 acts on the drive gear 921, the drive motor 922 can control the drive gear 921 to avoid reverse rotation through its own torque, thereby continuously limiting the rotation angle of the connecting pipe 10, which also limits the spraying angle of the high-pressure nozzle 3.

[0090] When the drive motor 922 stops running, the torque on the drive gear 921 disappears. At this time, the connecting pipe 10 returns to its original position under the action of the return spring 912, and drives the adjusting gear 924 and the drive gear 921 to rotate and return to their original positions.

[0091] In this embodiment, the drive motor 922 is a model of motor that can control the amount of rotation in the prior art, thereby controlling the amount of rotation of the drive gear 921 and achieving the purpose of controlling the rotation angle of the connecting pipe 10.

[0092] In this embodiment, the drive motor 922 can also adopt an angle adjustment device in the prior art, so that the rotation amount of the drive gear 921 can be controlled to achieve the purpose of controlling the rotation amount of the adjustment gear 924, and the rotation angle of the connecting pipe 10 can be determined according to the rotation amount of the adjustment gear 924.

[0093] Furthermore, the nozzle support base includes a connecting part 7, the upper part of the connecting part 7 is fixed to the lifting rail 2, a reinforcing rib 6 is fixed on the connecting part 7, the bottom of the reinforcing rib 6 is fixed to the connecting part 7, and the side of the reinforcing rib 6 is fixed to the lifting rail 2;

[0094] A support part 8 is fixed below the connecting part 7. The support part 8 is fixed to the connecting pipe 10. The connecting pipe 10 passes through the support part 8 and the connecting part 7 and communicates with the water-air mixing base 4.

[0095] The lifting track 2 includes a support plate 22, which is perpendicular to and fixedly connected to the connecting part 7. A guide track 21 is fixed on the support plate 22, and the axis of the guide track 21 is perpendicular to the connecting part 7.

[0096] In this embodiment, the connecting part 7 in the nozzle support base is used to connect the lifting rail 2 and provide a accommodating position for the lifting rail 2. The reinforcing rib 6 on the connecting part 7 can effectively improve the stability of the lifting rail 2 on the nozzle support base. The support part 8 is used to bear the weight and adjust the angle according to the rotation of the connecting pipe 10, thereby achieving the purpose of adjusting the spray angle of the high-pressure nozzle 3 mounted on it.

[0097] The support plate 22 is perpendicular to the connecting part 7, so the lifting track 2 can be adjusted to a wider range of heights. The guide track 21 is used to support the lifting sliding base 5 and to provide a sliding trajectory limit for the lifting sliding base 5. The connection between the connecting pipe 10 and the water-air mixing base 4 is achieved through a flexible hose or telescopic pipe, thereby avoiding the impact of the lifting of the water-air mixing base 4 on the water mist delivery.

[0098] Furthermore, the water-air mixing base 4 includes an outer frame 41, which is fixed to the lifting sliding base 5. A mixing box 42 is fixed inside the outer frame 41. The mixing box 42 is provided with a plurality of air inlet ducts 43, which extend to the outside of the mixing box 42 to form an air inlet 44.

[0099] The mixing chamber 42 is connected to the high-pressure nozzle 3.

[0100] In this embodiment, the water mist concentration produced in the spray host C or the backup host D is relatively high, which can effectively improve the water mist delivery efficiency. However, when the water mist with high water content is sprayed onto the fins, it will form a partial dripping state, which will cause a large loss in the actual water mist delivery process, resulting in a large waste. In this embodiment, by setting a water-air mixing base 4 in front of the high-pressure nozzle 3, the water mist delivered to the high-pressure nozzle 3 is mixed with air, thereby reducing the water content of the sprayed water mist. This ensures the water mist delivery efficiency and also allows more water mist to form an evaporative cooling effect when sprayed onto the fins, thereby avoiding resource waste, improving the resource utilization rate of this embodiment in practical applications, and forming higher economic benefits.

[0101] The fins of air conditioner outdoor units are usually made of aluminum. The main reason for avoiding corrosion is that a dense oxide film forms on the surface of the fins with the air. However, if the fins are immersed in water mist with high water content for a long time, there is also a risk of corrosion. In this embodiment, the water content of the water mist sprayed onto the fins is reduced by mixing some air into the water mist with high water content in the mixing chamber 42. This reduces the time that the liquid stays on the fins and reduces the risk of damage to the oxide film on the surface of the fins. Thus, the purpose of protecting the fins for long-term continuous use is achieved while ensuring the cooling effect.

[0102] In this embodiment, a water mist with a high moisture content is introduced into the mixing chamber 42 through the connecting pipe 10, and sufficient air is introduced from the air inlet 44 through the air inlet duct 43. After the air and water mist are mixed, the water mist with a suitable moisture content is sprayed onto the fins of the air conditioner outdoor unit through the high-pressure nozzle 3 to achieve cooling. In this embodiment, air is pumped into the mixing chamber 42 at the location of the air inlet duct 43 using an existing air pump. The air pump adopts existing technology.

[0103] In this embodiment, the high-pressure nozzle 3 adopts a high-pressure atomizing nozzle that can spray water mist in the prior art, so as to maintain the stability of the high-pressure nozzle 3 while spraying water mist to cool the fins of the air conditioner outdoor unit, thereby improving the high availability of this embodiment.

[0104] In this embodiment, the anti-tipping cone 101 effectively provides lateral support to the connecting pipe 10. The anti-tipping cone 101 is connected to the outer wall of the connecting pipe 10 via a bearing, ensuring that the anti-tipping cone 101 provides lateral support without affecting the rotational behavior of the connecting pipe 10. This embodiment, by using the anti-tipping cone 101, not only improves the stability of the connecting pipe 10 and prevents it from being damaged by shear stress, but also effectively enhances the overall load-bearing capacity of the connecting pipe 10.
