Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a water circulation device for auxiliary cooling of an air conditioner outdoor unit. Background Art

[0002] The outdoor unit of the air conditioner refers to the outdoor equipment of the air conditioner. It is an important part of the air conditioning system. It is mainly responsible for transferring indoor heat to the outdoors to achieve the purpose of regulating indoor temperature or humidity. During the operation of the air conditioner, the outdoor unit of the air conditioner acts as a heat dissipation component, and its working efficiency directly affects the overall performance of the air conditioner. When the ambient temperature is high, it is difficult for the outdoor unit of the air conditioner to dissipate heat, which may cause the operating temperature of components such as the compressor to rise, which will not only reduce the cooling efficiency of the air conditioner, but also the compressor and other components may shut down due to overheating protection, affecting the normal use of the air conditioner and even shortening the service life of the air conditioner. Therefore, during the actual operation of the outdoor unit of the air conditioner, it is also necessary to equip it with an auxiliary cooling device to timely assist in cooling the outdoor unit of the air conditioner.

[0003] At present, the auxiliary cooling methods of the air conditioner outdoor unit mainly include increasing the area of ​​the cooling fins, increasing the fan speed and water cooling. Among them, water cooling is to atomize the water and spray it on the heat pipe in a spraying manner, so that the circulating medium inside the heat pipe can exchange heat with the atomized water, thereby improving the heat dissipation efficiency of the heat pipe. However, when the atomized water contacts the heat pipe, due to the single spray direction, there are often spray dead corners on the heat pipe that cannot be contacted by the atomized water, and the atomized water is not easy to adhere evenly to the heat pipe, resulting in poor heat dissipation effect and low water resource utilization.

[0004] Referring to the Chinese patent document with announcement number CN112344447B and announcement date November 5, 2021, entitled A water circulation energy-saving device for air conditioning refrigeration, an adjustable nozzle is used to complete the spraying of atomized water. It can increase the spraying area of ​​atomized water while making the atomized water spray evenly, thereby improving the cooling effect on the air conditioner outdoor unit.

[0005] Referring to the above technical solution, when the atomized water is sprayed onto the heat pipe, due to the surface tension of the atomized water, the atomized water will still adhere to the heat pipe after absorbing heat. In this case, the high-temperature atomized water attached to the surface of the heat pipe may cause the subsequent sprayed low-temperature atomized water to be difficult to adhere normally, and when the subsequent sprayed low-temperature atomized water contacts the high-temperature atomized water attached to the surface of the heat pipe, due to the influence of heat transfer, the temperature of the low-temperature atomized water will rise, which is easy to affect the auxiliary cooling effect of the air conditioner outdoor unit. At the same time, in order to compensate for the temperature increase caused by the high-temperature atomized water, it is necessary to increase the energy input of the cooling system, which will increase energy consumption. Summary of the invention

[0006] In view of this, the present application provides a water circulation device for auxiliary cooling of an air conditioner outdoor unit, which is mainly used to solve the problem that high-temperature atomized water attached to the surface of the heat pipe easily affects the auxiliary cooling effect of the air conditioner outdoor unit.

The two water distribution plates abut against the pressure block on the left side in a conical manner, and the two wiper plates abut against the pressure block on the right side in a conical manner. When the cylinder drives the pressure block to move downward, the two water distribution plates or the two wiper plates abutting against the pressure block will approach each other.

[0012] Optionally, a water storage tank is provided at the bottom of the chassis and is located directly below the heat dissipation pipe. A circulation pipe provided inside the water storage tank is connected to a liquid supply pipe of the atomizing nozzle.

[0013] By adopting the above technical solution, the water storage tank can recycle the atomized water and supply it to the atomizing nozzle again.

[0014] Optionally, a filter screen is provided at the water inlet of the circulation pipe.

[0015] By adopting the above technical solution, the filter can filter out impurities that may exist in the circulating water, so as to prevent the subsequent atomization spraying work from being interfered by the impurities.

[0016] Optionally, the circulation pipe is arranged horizontally at the bottom of the chassis in a piston cylinder shape, and a piston rod that can be abutted by a vertical plate is slidably connected to the inside of the circulation pipe through a spring, so as to back-blow and clear blockages of the filter screen.

[0017] By adopting the above technical solution, when the piston rod is abutted by the vertical plate, it will overcome the elastic force of the spring and move inside the circulation pipe, thereby generating a certain back-blowing force to clean the impurities accumulated on the filter screen.

[0018] Optionally, a vibration component is provided between the circulation pipe and the piston rod to shake off the high-temperature atomized water on the two wiper blades.

[0019] Optionally, the vibration component includes a spiral groove arranged on the inner wall of the circulation tube, the piston rod is provided with a convex pin located inside the spiral groove, and the piston rod is hollow and filled with a plurality of steel balls.

Figure 1-Figure 5 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0027] Reference Figure 1 and Figure 2 This embodiment provides a water circulation device for auxiliary cooling of an air conditioner outdoor unit, including a chassis 1 and an atomizing nozzle 11 arranged inside the chassis 1 and ... Figure 4 ), cooling fan 12, heat dissipation pipe 13, water storage tank 5 and atomized water treatment mechanism. The spraying direction of the atomizing nozzle 11 and the air supply direction of the cooling fan 12 are both facing the heat dissipation pipe 13. The water storage tank 5 is located directly below the heat dissipation pipe 13 and can recycle the atomized water. The circulation pipe 6 arranged inside the water storage tank 5 is connected with the liquid supply pipe of the atomizing nozzle 11. With the cooperation of the external refrigerant, the atomizing nozzle 11 can use the atomized water cooled again inside the water storage tank 5 for the spraying work, thereby realizing the recycling of the atomized water.

[0028] Among them, refer to Figure 2 and Figure 3The atomized water treatment mechanism includes a linear driver 2, a vertical plate 21, two water distribution plates 22, a sponge cover 23, an extrusion plate 24, two wipers 25, a tension spring 3 and a drive assembly 4. The linear driver 2 is arranged inside the chassis 1, the vertical plate 21 is arranged at the execution end of the linear driver 2 and can move laterally along the heat dissipation pipe 13; the two water distribution plates 22 are symmetrically arranged front and back and are connected to the left side of the vertical plate 21 by longitudinal sliding through the tension spring 3, the two water distribution plates 22 are both provided with a sponge cover 23, and the sponge cover 23 can abut the heat dissipation pipe 13 when the two water distribution plates 22 approach each other, the extrusion plate 24 is arranged on the left side of the chassis 1 and can abut the sponge cover 23; the two wipers 25 are symmetrically arranged front and back and are connected to the right side of the vertical plate 21 by longitudinal sliding through the tension spring 3, and the two wipers 25 can abut the heat dissipation pipe 13 when they approach each other; the drive assembly 4 is arranged between the chassis 1 and the vertical plate 21, and is used to drive the two water distribution plates 22 or the two wipers 25 to approach each other.

[0029] Among them, refer to Figure 2 and Figure 3 The driving assembly 4 includes two cylinders 41 arranged on the top of the vertical plate 21, and the execution ends of the two cylinders 41 are provided with pressure blocks 42. The two water distribution plates 22 abut against the pressure block 42 on the left side in a conical manner, and the two wiper plates 25 abut against the pressure block 42 on the right side in a conical manner. When the cylinder 41 drives the pressure block 42 to move downward, the two water distribution plates 22 or the two wiper plates 25 abutting against the pressure block 42 will approach each other.

[0030] When the atomizing nozzle 11 and the cooling fan 12 cooperate to carry out the cooling work on the heat dissipation tube 13, the linear drive 2 operates to drive the vertical plate 21 to move from right to left. In this process, the two water distribution plates 22 can be moved closer to each other through the cooperation of the driving component 4, while the two wiper plates 25 are in a back-to-back state under the action of the tension spring 3, so that the sponge cover 23 can evenly spread the low-temperature atomized water attached to the heat dissipation tube 13; when the vertical plate 21 moves to the leftmost end, the low-temperature atomized water adsorbed in the sponge cover 23 will be squeezed out by the squeezing plate 24 and the vertical plate 21 to avoid The temperature of these low-temperature atomized waters increases as the heat dissipation work proceeds and affects the temperature of the low-temperature atomized water sprayed out subsequently; when the linear actuator 2 drives the vertical plate 21 to move from left to right, the two water distribution plates 22 are in a back-to-back state under the action of the tension spring 3, while the two wiper plates 25 are in a facing state through the cooperation of the drive component 4, so as to scrape off the high-temperature atomized water that has absorbed heat on the heat dissipation pipe 13 and is converted from the low-temperature atomized water, thereby reducing the influence of the high-temperature atomized water attached to the surface of the heat dissipation pipe 13 on the auxiliary cooling effect of the air-conditioning outdoor unit.

[0031] Reference Figure 3 The whole formed by the two wipers 25 is provided with a guide step 251 for guiding the high-temperature atomized water scraped off the heat dissipation pipe 13 by the wipers 25 downward.

[0032] Since the heat dissipation pipe 13 is usually arranged in the form of a serpentine pipe, with the cooperation of the guide step 251, after the wiper 25 scrapes the high-temperature atomized water on the heat dissipation pipe 13, the high-temperature atomized water will directly enter the water storage tank 5 along the guide step 251 to prevent the high-temperature atomized water scraped off the surface of the upper heat dissipation pipe 13 from dripping downwards and re-attaching to the surface of the lower heat dissipation pipe 13.

[0033] Reference Figure 4 and Figure 5 A filter screen 61 is provided at the water inlet of the circulation pipe 6. The circulation pipe 6 is arranged horizontally at the bottom of the chassis 1 in the shape of a piston cylinder, and a piston rod 62 that can be abutted by the vertical plate 21 is slidably connected to the inside of the circulation pipe 6 through a spring 63, which is used to back-blow and clear the filter screen 61.

[0034] When the atomized water collected in the water storage tank 5 is recycled, the filter 61 can filter out impurities that may exist in the circulating water to prevent the subsequent atomization spraying work from being interfered with by the impurities, and during the movement of the vertical plate 21, when the vertical plate 21 abuts against the piston rod 62, the piston rod 62 will overcome the elastic force of the spring 63 and displace inside the circulation pipe 6, thereby generating a certain backblowing force to clean up the impurities accumulated on the filter 61, so as to prevent the filter 61 from being blocked by impurities and affecting its own filtering effect.

[0035] Reference Figure 5 A vibration assembly 7 is provided between the circulation pipe 6 and the piston rod 62, and is used to shake off the high-temperature atomized water on the two wiper blades 25. The vibration assembly 7 includes a spiral groove 71, a convex pin 72 and a steel ball 73. The spiral groove 71 is provided on the inner wall of the circulation pipe 6, the convex pin 72 is provided on the piston rod 62 and is always located inside the spiral groove 71, and the piston rod 62 is hollow and filled with a plurality of steel balls 73.

[0036] While the piston rod 62 moves, the piston rod 62 also rotates by the cooperation of the spiral groove 71 and the protruding pin 72. At this time, the steel ball 73 moves inside the piston rod 62 due to gravity and collides with the inner cavity wall of the piston rod 62. When the vibration generated by the collision is transmitted to the vertical plate 21 and the wiper plate 25, the high-temperature atomized water on the wiper plate 25 will be shaken off, so as to prevent the high-temperature atomized water from dripping onto the heat pipe 13 again when the wiper plate 25 returns and affecting the heat dissipation.

[0037] The implementation principle of a water circulation device for auxiliary cooling of an air conditioner outdoor unit in the embodiment of the present application is as follows: When the atomizing nozzle 11 and the cooling fan 12 cooperate to carry out the cooling work on the heat dissipation tube 13, the linear drive 2 drives the vertical plate 21 to move from right to left. In this process, the two water distribution plates 22 can be moved closer to each other through the cooperation of the driving component 4, while the two wiper plates 25 are in a back-to-back state under the action of the tension spring 3, so that the sponge cover 23 can evenly spread the low-temperature atomized water attached to the heat dissipation tube 13.

[0038] When the vertical plate 21 moves to the leftmost end, the low-temperature atomized water adsorbed inside the sponge sleeve 23 will be squeezed out by the extrusion plate 24 and the vertical plate 21 to prevent the temperature of the low-temperature atomized water from rising as the heat dissipation work proceeds and affecting the temperature of the low-temperature atomized water sprayed out subsequently.

[0039] When the linear drive 2 drives the vertical plate 21 to move from left to right, the two water distribution plates 22 are in a back-to-back state under the action of the tension spring 3, while the two wiper plates 25 are in a facing state through the cooperation of the drive component 4, so as to scrape off the high-temperature atomized water that has absorbed heat on the heat pipe 13 and is converted from the low-temperature atomized water, thereby reducing the influence of the high-temperature atomized water attached to the surface of the heat pipe 13 on the auxiliary cooling effect of the air conditioner outdoor unit.

[0040] When the atomized water collected in the water storage tank 5 is recycled, the filter 61 can filter out impurities that may exist in the circulating water to prevent the subsequent atomization spraying work from being interfered with by the impurities, and during the movement of the vertical plate 21, when the vertical plate 21 abuts against the piston rod 62, the piston rod 62 will overcome the elastic force of the spring 63 and displace inside the circulation pipe 6, thereby generating a certain backblowing force to clean up the impurities accumulated on the filter 61, so as to prevent the filter 61 from being blocked by impurities and affecting its own filtering effect.

[0041] While the piston rod 62 moves, the piston rod 62 also rotates by the cooperation of the spiral groove 71 and the protruding pin 72. At this time, the steel ball 73 moves inside the piston rod 62 due to gravity and collides with the inner cavity wall of the piston rod 62. When the vibration generated by the collision is transmitted to the vertical plate 21 and the wiper plate 25, the high-temperature atomized water on the wiper plate 25 will be shaken off, so as to prevent the high-temperature atomized water from dripping onto the heat pipe 13 again when the wiper plate 25 returns and affecting the heat dissipation.

[0042] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
