Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a high-efficiency heat dissipation system for an outdoor unit of an air conditioner. Background Technology

[0002] Air conditioning generally includes several major parts such as cold / heat source equipment, cold / heat medium distribution system, terminal devices, and other auxiliary equipment; the main components include: refrigeration unit, water pump, fan and piping system, while the terminal devices are responsible for using the distributed cold and heat to specifically process the air condition so that the air parameters of the target environment meet certain requirements.

[0003] In related technologies, to achieve intelligent energy-saving and cooling functions in air conditioners, patent CN217357298U provides an intelligent cooling and energy-saving device and air conditioner. In this solution, a condensate collection unit collects and reuses the condensate generated by the air conditioner itself, using it to cool the air conditioner, thereby reducing the operating temperature of the outdoor unit and the temperature of the heat sink. This ensures stable operation of the air conditioner, reduces its failure rate, saves water, and lowers costs. However, in practical applications, the amount of condensate generated is limited, especially in high-temperature environments where the condensate itself contains heat, resulting in limited cooling effect on the condenser of the outdoor unit. Furthermore, due to the slow circulation of condensate, dirt easily accumulates at the bottom of the outdoor unit, requiring regular cleaning, which is inconvenient. To address these technical problems, I have previously filed a utility model patent application with application number 2025214940552, entitled "A Cooling System for an Outdoor Unit of an Air Conditioner." In this patent, a water circulation system is used in conjunction with condensate to cool the condenser. However, I have found that although the above structure can effectively improve the cooling effect of the condenser, the cooling efficiency is not very high in hot weather and needs to be improved.

[0013] Preferably, there are three water curtains, which are respectively arranged on three sides of the outdoor unit of the air conditioner, and the condenser is arranged on the remaining side.

[0014] Preferably, there are four water spray nozzles, three of which are arranged directly above the water curtain, and the remaining one is arranged directly above the condenser.

[0015] Preferably, the first water pipe includes a first main pipe, a first multi-way connector, and several first branch pipes, wherein the first main pipe is connected between the water pump and the first multi-way connector, and the first branch pipes are disposed between the first multi-way connector and the water spray head.

[0022] Compared with the prior art, this utility model has the following beneficial effects:

[0023] 1. The outdoor unit of the air conditioner has air intakes on four sides, with water curtains installed on three sides and a condenser on the remaining side. A water tank, spray nozzles, and a water pump are installed inside the outdoor unit. The water tank is connected to an external tap, which continuously feeds the water into the tank and pumps it to the spray nozzles. Condensate from the indoor unit also enters the spray nozzles. Each spray nozzle continuously sprays water onto the condenser and the water curtain paper. Combined with the continuous outward exhaust from the internal fan, the air inside the outdoor unit experiences accelerated convection, resulting in a faster airflow and velocity. This accelerates the evaporation of water from the water curtain paper, lowering the temperature of the air entering the outdoor unit and reducing or maintaining the water temperature. This effectively cools the condenser, resulting in excellent heat dissipation.

[0024] 2. After the water level in the water tank rises to the overflow port, the water inside will overflow into the main drain pipe through the fourth water pipe, thus ensuring that the water in the water tank continues to circulate and will not be too hot. In conjunction with the water curtain and fan, it can accelerate the cooling of the condenser and help save energy. Attached Figure Description

[0035] Detailed implementation plan: See below Figures 1-4This utility model is a high-efficiency heat dissipation system for an air conditioner outdoor unit 2. A second water pipe 3 is provided between the air conditioner outdoor unit 2 and the air conditioner indoor unit 1. The second water pipe 3 is used to guide the condensate in the air conditioner indoor unit 1 to the air conditioner outdoor unit 2. The air conditioner outdoor unit 2 is equipped with a condenser 21. The high-efficiency heat dissipation system includes:

[0036] Fan 26 is installed at the upper position of outdoor unit 2 of air conditioner;

[0037] At least one water curtain 22 is arranged on the side of the outdoor unit 2 of the air conditioner;

[0038] Several water spray nozzles 23 are fixed inside the outdoor unit 2 of the air conditioner and are respectively arranged directly above the water curtain 22 and the condenser 21;

[0039] The water tank 24 with its opening facing upward is installed inside the outdoor unit 2 of the air conditioner and is located below the water curtain 22 and the condenser 21. The fan 26 is used to continuously exhaust air outward.

[0040] A water pump 251 is installed at the bottom of the water tank 24, and a first water pipe 25 is provided between the water pump 251 and the water spray head 23.

[0041] The third water pipe 4 is connected at one end to the inlet 241 of the water tank 24, and at the other end to the tap water pipeline.

[0042] In a preferred embodiment of this invention, there are three water curtains 22, which are respectively arranged on three sides of the outdoor unit 2 of the air conditioner, and the condenser 21 is arranged on the remaining side.

[0043] Here, since the outdoor unit 2 of the air conditioner is generally rectangular, it has a top surface, a bottom surface, and four sides. Therefore, by setting water curtains 22 on three of the sides and using filters, outside air can enter the outdoor unit 2 through the water curtains 22. Note that in this embodiment, four-sided air intake can be selected, that is, an air inlet is also set on the side where the water spray nozzles 23 are set, and the air outlet of the outdoor unit 2 is set on the upper side of the outdoor unit.

[0044] Then, in this embodiment, there are four water spray nozzles 23, three of which are arranged directly above the water curtain 22, and the remaining water spray nozzle 23 is arranged directly above the condenser 21.

[0045] Please see Figure 1 In this embodiment, the first water pipe 25 includes a first main pipe 252, a first multi-way connector 253 and several first branch pipes 254, wherein the first main pipe 252 is connected between the water pump 251 and the first multi-way connector 253, and the first branch pipes 254 are disposed between the first multi-way connector 253 and the water spray nozzle 23.

[0046] In addition, in this embodiment, the second water pipe 3 includes a second main pipe 32, a second multi-way connector 33 and several second branch pipes 34, wherein the second main pipe 32 is connected between the air conditioner indoor unit 1 and the second multi-way connector 33, and the second branch pipes 34 are disposed between the second multi-way connector 33 and the water spray head 23.

[0047] Here, both the first multi-way connector 253 and the second multi-way connector 33 are five-way connectors. The water pumped by the water pump 251 from the water tank 24 first enters the first main pipe 252, and then flows through the first multi-way connector 253 to each first branch pipe 254, and continues to flow into the water spray head 23.

[0048] Then, the condensate flowing out of the second main pipe 32 is distributed through the second multi-port connector 33 to each of the second branch pipes 34, and continues to flow into the water spray nozzles 23.

[0049] Next, please refer to Figure 1 and Figure 4 In this embodiment, the indoor unit 1 of the air conditioner (cabinet type or wall-mounted type) is provided with a water tank 11 for holding condensate, and the indoor unit 1 of the air conditioner is provided with a drain outlet corresponding to the water tank 11, and one end of the second main pipe 32 is connected to the drain outlet.

[0050] Next, please refer to Figure 1 and Figure 2 As can be seen, in this embodiment, the water tank 24 is also provided with an overflow port 242. The overflow port 242 is located above the water inlet 241. The overflow port 242 is used to connect the fourth water pipe 5. One end of the fourth water pipe 5 extends to the outside of the air conditioner outdoor unit 2.

[0051] Working principle of the cooling system: When it is necessary to enhance the cooling effect of the condenser 21 in the outdoor unit 2 of the air conditioner, the third water pipe 4 is connected to the outdoor unit 2 of the air conditioner, and one end of the third water pipe 4 is connected to a tap. Tap water is continuously supplied to the water tank 24. The water pump 251 located in the water tank 24 draws water from the water tank 24 to the spray nozzles 23. The condensate in the water tank 11 is also continuously supplied to the spray nozzles 23. Each spray nozzle 23 receives the condensate and tap water and sprays it downwards, cooling the condenser 21 and the water curtain paper located directly below the spray nozzles 23. The water flowing down from the spray will fall into the water tank 24. Since it is necessary to keep the water temperature in the water tank 24 low, the water in the water tank 24 needs to be drained in time. When the water level in the water tank 24 reaches the height of the overflow port 242, the water is discharged through the overflow port 242 into the fourth water pipe 5 and continues to be discharged to the outside of the outdoor unit 2 of the air conditioner.

[0052] Here, the outdoor unit 2 of the air conditioner has a total of four air intakes, three of which are equipped with water curtains 22, and the remaining one is equipped with a condenser 21. By installing a water tank 24, water spray nozzles 23 and a water pump 251 inside the outdoor unit 2, and connecting the water tank 24 to an external tap water supply, the external tap water will continuously enter the water tank 24 and be pumped to the water spray nozzles 23 by the water pump 251. The condensate formed in the indoor unit 1 of the air conditioner will also enter the water spray nozzles 23. Each water spray nozzle 23 continuously sprays water onto the condenser 21 and the water curtain 22. With the fan 26 located above continuously drawing air outward, the air inside the outdoor unit of the air conditioner will generate convection acceleration, and the water on the water curtain 21 will evaporate faster. The temperature of the air entering the outdoor unit 2 will decrease, thus better cooling the condenser 21 and achieving good heat dissipation.

[0053] Then, please see Figure 1 As can be seen, in this embodiment, the bottom of the water tank 24 is provided with a drain outlet, which is used to connect to the drain pipe 6. The fourth water pipe 5 and the drain pipe 6 are both connected to the main drain pipe 7. An automatic drain pump 61 is provided on the extension path of the drain pipe 6. The automatic drain pump 61 is installed inside the air conditioner outdoor unit 2.

[0054] The automatic sewage pump 61 and sewage pipe 6 are installed here to periodically drain the dirt remaining at the bottom of the water tank 24. The working principle of the automatic sewage pump 61 is existing technology and will not be explained in detail here. The automatic sewage pump 61 can be operated remotely via a remote control.

[0055] Please see Figure 1 and Figure 2 In order to better see the water level in the water tank 24, a liquid level float ball 27 is installed in the water tank 24 in this embodiment.

[0056] More specifically, in order to more efficiently transport the condensate in the indoor unit 11 of the air conditioner to the spray nozzle 23, in this embodiment, a booster pump 31 is provided on the extension path of the second water pipe 3.

[0057] In addition, the booster pump 31 ensures that when the outdoor unit 2 is installed at a higher height than the indoor unit 1, the condensate formed in the indoor unit 1 can be smoothly delivered to the spray nozzle 23.

[0058] The above description of a high-efficiency heat dissipation system for an outdoor unit of an air conditioner is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
