Technical Field

[0001] The utility model particularly relates to a dustproof system of an air-conditioning outdoor unit and an air-conditioning outdoor unit. Background Art

[0002] In existing technology, during daily operation, the fins at the heat dissipation outlets of computer room air conditioner outdoor units accumulate a large amount of dust and lint, which affects the heat dissipation of the outdoor units and may cause the compressor of the computer room air conditioner to shut down due to high pressure. Furthermore, the fins are layered, making manual cleaning and flushing time-consuming and potentially damaging the fins during cleaning.

[0003] To prevent dust, catkins, and other debris from accumulating on the fins and causing blockage, which could affect heat dissipation, two common protection and management schemes are currently used for air conditioner outdoor units in computer rooms. The first scheme consists of five protective surfaces sewn together into a rectangular outer cover: front, rear, left, right, and top. The protective surfaces are made of waterproof fabric. The front and rear protective surfaces are each reserved for an air outlet and air inlet that match the air inlet and outlet of the air conditioner outdoor unit. A wiring port is reserved on one side to match the wiring port. Covers are attached to these reserved ports using adhesive tape. The second scheme consists of a rectangular cover slightly larger than the air conditioner outdoor unit. The bottom of the cover is hollow, and the sides have slots to allow for the refrigerant pipes.

[0004] The above two solutions have the following problems: First, dust or fluff on the outer surface of the outer shell in the first solution or the cover in the second solution may accumulate over a period of time (for example, when the air is full of concentrated fluff), requiring a lot of manpower to maintain and clean, otherwise it will affect the heat dissipation effect of the air conditioner outdoor unit; Second, the outer shell in the first solution or the cover in the second solution are fixed on the air conditioner outdoor unit, which is difficult and costly to disassemble, causing great inconvenience to the daily maintenance work of the air conditioner outdoor unit.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by various orientation terms are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] Some embodiments of the present invention provide a dust prevention system for an air conditioner outdoor unit, such as Figures 1 to 3 As shown, the dust prevention system 00 of the air conditioner outdoor unit (hereinafter referred to as the dust prevention system 00) includes a dust prevention device 11 and a flushing device 12. The dust prevention device 11 is detachably mounted on the frame outside the heat dissipation port 101 of the air conditioner outdoor unit. The flushing device 12 is arranged near the frame outside the heat dissipation port of the air conditioner outdoor unit 10. The flushing device 12 includes a water pipe 121 and a water flow control device 122. One end of the water pipe 121 is connected to a water source, and a portion of the water pipe 121 located near the frame outside the heat dissipation port 101 of the air conditioner outdoor unit is provided with a plurality of water outlets 123. The water flow control device 122 is arranged on the water pipe 121, and the water flow control device 122 is used to control the water flow from the water source into the water pipe 121, and to make water flow out from the plurality of water outlets 123 to flush the dust prevention device 11.

[0029] As can be understood, the dustproof device 11 is disposed on the frame outside the heat dissipation port 101 of the air conditioner outdoor unit. Thus, the dustproof device 11 can isolate the heat dissipation port 101 from external dust, fluff, etc., thereby preventing dust, fluff, etc. from accumulating on the fins and causing blockage, thereby affecting the heat dissipation effect of the air conditioner outdoor unit. Since the dustproof device 11 is detachably mounted on the air conditioner outdoor unit, it can be easily removed when routine maintenance of the air conditioner outdoor unit is required, facilitating maintenance by personnel.

[0030] Exemplarily, the dustproof device 11 can be detachably mounted on the air conditioner outdoor unit by means of a snap connection, a hinge connection, a magnetic attraction, or the like.

[0031] It is understandable that when dust, fluff, etc. accumulate on the dustproof device 11, the flushing device 12 can flush away the dust, fluff, etc. without affecting the heat dissipation of the fins. Maintenance personnel can remotely control the water flow control device 122 to regularly flush the dustproof device 11 to ensure that there is no accumulation of fluff or dust on the outside of the dustproof device 11, further reducing the maintenance workload of maintenance personnel. After the flushing device 12 stops flushing, there will be residual moisture on the dustproof device 11. The hot air blown out from the fins can evaporate the moisture remaining on the dustproof device 11, and the mixture of water, dust, and fluff will not be caused to clog the dustproof device 11. In addition, the evaporation of moisture remaining on the dustproof device 11 can carry away heat, which helps to improve the heat dissipation effect of the air conditioner outdoor unit.

[0032] It can be understood that one end of the water pipe 121 is connected to the water source, and the other end can be closed or not. For example, some computer rooms have many air-conditioning outdoor units, and multiple air-conditioning outdoor units can share a water pipe to achieve simultaneous flushing of the dust device 11 set at the heat dissipation outlet 101 of each air-conditioning outdoor unit.

[0033] It is understood that the water flow control device 122 can be set to turn the water flow on and off at a fixed time, thereby achieving periodic flushing of the dustproof device 11. In this way, the dustproof device 11 can be maintained and repaired during maintenance or inspection of the air conditioner outdoor unit, without requiring much manpower. For example, the water flow control device 122 can be a water flow control device used in a garden irrigation system.

[0034] In some embodiments, as Figure 4 As shown, the dustproof device 11 includes a frame 111 and a multi-mesh yarn 112, and the multi-mesh yarn 112 is fixed in the frame 111. The frame 111 is detachably mounted on the frame outside the heat dissipation outlet 101 of the air conditioner outdoor unit so that the multi-mesh yarn is arranged outside the heat dissipation outlet 101 of the air conditioner outdoor unit.

[0035] In some embodiments, the area of ​​the multi-mesh yarn 112 is greater than or equal to the area of ​​the heat dissipation outlet 101 of the air conditioner outdoor unit.

[0036] For example, Figure 2 As shown, some computer room air conditioners have extremely high requirements for heat dissipation, and the size of the air conditioner outdoor unit is limited. The heat dissipation port of the computer room air conditioner outdoor unit almost fills the entire back of the computer room air conditioner outdoor unit. When the dustproof device 11 completely covers the heat dissipation port, the area of ​​the multi-mesh yarn 112 is equal to or almost equal to the area of ​​the heat dissipation port 101 of the air conditioner outdoor unit.

[0037] For example, Figure 5 As shown, the heat dissipation vents of some common air conditioners or some machine room air conditioners do not fill one surface of the entire air conditioner outdoor unit (for example, do not fill the back of the air conditioner outdoor unit). A dustproof device 11 slightly larger than the heat dissipation vent can be provided to ensure a better dustproof effect.

[0038] In some embodiments, the frame 111 is an aluminum alloy frame.

[0039] Understandably, the advantages of aluminum alloy frames include: light weight, high strength, corrosion resistance, strong plasticity, sustainability, and good cost-effectiveness. For example, light weight: The density of aluminum alloy is about one-third of that of iron. It is light weight and high strength. This allows aluminum alloy to withstand greater forces without deformation under the same size, and is widely used in vehicles and building structures. High strength: Aluminum alloy has high strength, especially 6061-T6 aluminum alloy profiles, which have strength comparable to steel. It can withstand strong winds and impacts, providing better safety. Corrosion resistance: Aluminum alloy has good corrosion resistance and can be used for long-term without damage in harsh environments such as moisture and corrosive environments, reducing the frequency of maintenance and replacement and lowering the cost of use. Strong plasticity: Aluminum alloy has excellent plasticity and can be made into parts of various shapes and sizes through methods such as extrusion, stretching, rolling, and forging. The surface can be treated in a variety of ways to meet different design requirements. Sustainability: Aluminum alloy is a recyclable material and is environmentally friendly, reducing resource consumption and waste generation, and meeting environmental protection requirements. Cost-effectiveness: Although the initial cost of aluminum alloy may be higher, its long service life and the need for frequent maintenance and replacement make it more cost-effective in the long run.

[0040] In some embodiments, as Figure 6 As shown, a plurality of magnet pieces 113 are fixedly mounted on one side of the frame 111. The frame 111 is adsorbed on the frame outside the heat dissipation outlet 101 of the air conditioner outdoor unit through the plurality of magnet pieces 113.

[0041] It can be understood that the air conditioner outdoor unit is made of metal, and the magnet sheet can be attracted to the air conditioner outdoor unit. The frame 111 is adsorbed on the frame outside the heat dissipation port 101 of the air conditioner outdoor unit through multiple magnet sheets 113. When the staff performs maintenance work on the air conditioner outdoor unit, they can easily remove the dustproof device 11 from the air conditioner outdoor unit.

[0042] For example, a multi-mesh yarn of approximately the same size as the fin frame is designed and installed on the rear side of the air conditioner outdoor unit, that is, the fin side. The multi-mesh yarn is fixed with an aluminum alloy frame on all sides, and multiple magnets are attached to one side of the aluminum alloy frame. The size of the aluminum alloy frame and the magnets can be set according to the size of the air conditioner outdoor unit. The aluminum alloy frame can be magnetically attracted to the air conditioner fin frame. The dust-proof device configured in this way has a light structure and is easy to disassemble and maintain later.

[0043] In some embodiments, as Figure 1 and Figure 2 As shown, the water pipe 121 is arranged above the frame outside the heat dissipation outlet 101 of the air conditioner outdoor unit. A plurality of water outlet holes 123 are evenly distributed at the bottom of the water pipe 121 and face the dustproof device 11.

[0044] It can be understood that such an arrangement can utilize gravity to allow water to flow out naturally downward, and can accurately and evenly rinse the multi-mesh yarn 112.

[0045] It can be understood that the number and size of the water outlets in the plurality of water outlets 123 can be set according to the transverse length of the heat dissipation port. For example, 15-25 0.5cm diameter holes are set according to the transverse length of the heat dissipation port 101 of the air conditioner outdoor unit.

[0046] In some embodiments, as shown in Figure 7 The water pipe 121 is fixedly arranged in the clamping piece 124, and the clamping piece 124 is fixed above the frame outside the heat dissipation port 101 of the air conditioner outdoor unit.

[0047] It can be understood that such arrangement can protect and fix the water pipe 121, and can increase the service life of the water pipe 121 and the stability of the water flow from the plurality of water outlets 123 during use.

[0048] In some embodiments, as shown in Figure 8 The water flow control device 122 includes a valve 1221 and a water outlet controller 1222. The valve 1221 is arranged on the water pipe 12 and located between the water source 13 and the plurality of water outlets 123. The water outlet controller 1222 is connected with the valve 1221 and used for controlling the on-off of the water flow in the water pipe 121.

[0049] It can be understood that under normal use, the valve 1221 can be kept in an open state, and the on-off of the water flow is controlled by the water outlet controller 1222, and when maintenance or maintenance is needed, the valve 1221 can be closed. Exemplarily, the water outlet controller 1222 can adopt a double-pass timing irrigation machine with a model of DLXDQ-04-22 of Delixi Electrical.

[0050] In some embodiments, as shown in Figure 9 The water flow control device 122 further includes a pressure boosting valve 1223, which is arranged between the water outlet controller 1222 and the plurality of water outlets 123, and the pressure boosting valve 1223 is used for pressurizing the water flow flowing into the water pipe 121.

[0051] It can be understood that under the condition of low water pressure, the water outlet pressure at the plurality of water outlets 123 becomes small, which affects the flushing effect on the multi-eye yarn 112. At this time, the pressure boosting valve 1223 is used to pressurize the water flow, so that the water outlet pressure at the plurality of water outlets 123 can be increased, and the flushing effect on the multi-eye yarn 112 can be ensured, and the accumulation of dust, willow catkins and the like can be avoided to affect the heat dissipation effect of the air conditioner outdoor unit 10.

[0052] Some embodiments of the utility model provide an air conditioner outdoor unit, and the heat dissipation port of the air conditioner outdoor unit is provided with the dust prevention system of the air conditioner outdoor unit in any one of the above embodiments.

[0053] The specific solutions and beneficial effects of the air-conditioning outdoor unit provided by some embodiments of the present invention can be referred to the relevant description of the dust-proof system 00 of the air-conditioning outdoor unit mentioned above, which will not be repeated here.

[0054] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
