[0036] The following is for reference. Figures 1-3 The cooling fan assembly 100 according to the present invention can reduce the waste of cooling capacity, improve the utilization rate of cooling capacity, reduce the energy consumption of the cooling fan assembly 100, and improve the user experience and comfort.

[0037] like Figures 1-3As shown, a cooling fan assembly 100 according to an embodiment of the present invention includes: a cooling fan impeller 1, a wet curtain 2, a main water tank 4, and a second water tank 5.

[0038] The fan impeller 1 is constructed as a cross-flow impeller. The wet curtain 2 and the fan impeller 1 are distributed along the airflow direction of the fan impeller 1, and the wet curtain 2 is located on the air inlet side of the fan impeller 1. The main water tank 4 is used to supply water to the second water tank 5, and the second water tank 5 is equipped with a cold source 53. The top of the wet curtain 2 is equipped with a first water storage tank 6, the second water tank 5 is used to supply water to the first water storage tank 6, the first water storage tank 6 is used to supply water to the wet curtain 2, and the bottom of the wet curtain 2 is equipped with a second water storage tank 7. The second water storage tank 7 is used to collect water from the wet curtain 2 and also to supply water to one of the first water storage tank 6 and the main water tank 4.

[0039] Among them, the air cooler, also known as the air conditioning fan, is a type of air conditioner. The air cooler is equipped with a cold source 53 and has an internal refrigeration system. Water or refrigerant is cooled by passing through the cold source 53, such as ice crystals (usually a special gel or crystal). The airflow delivered by the air cooler impeller 1 can flow through the cooled water or refrigerant, thereby cooling the airflow and allowing the air cooler to blow out cold air, thus achieving the cooling effect. In addition, the air cooler is energy-saving and environmentally friendly, easy to move and carry, can increase indoor humidity, and ensure a good user experience.

[0040] Specifically, the air cooler assembly 100 is provided with an air cooler impeller 1, and the air cooler impeller 1 is correspondingly provided with a drive motor 31. The output shaft of the drive motor 31 is connected to the air cooler impeller 1. When the drive motor 31 runs, it can transmit power to the air cooler impeller 1 through the output shaft to make the air cooler impeller 1 rotate. When the air cooler impeller 1 rotates, it can drive the air around it to circulate. A motor mounting base 3 is provided in the air cooler assembly 100, and the drive motor 31 is fixedly installed in the motor mounting base 3. The output shaft of the drive motor 31 extends out of the motor mounting base 3 to connect with the air cooler impeller 1, ensuring the reliability of the operation of the drive motor 31 and the air cooler impeller 1.

[0041] Furthermore, the air cooler assembly 100 is also equipped with a wet curtain 2. Water cooled by the cold source 53 can flow through the wet curtain 2. The wet curtain 2 and the air cooler impeller 1 are distributed along the airflow direction of the air cooler impeller 1. When the air cooler impeller 1 is running, it can drive the airflow, which can flow through the wet curtain 2. The wet curtain 2, which is soaked in low-temperature water, can cool the airflow. The cooled airflow can be delivered to the room through the air cooler impeller 1 to cool the room. This ensures the environmental friendliness of the air cooler assembly 100 and increases the humidity of the airflow flowing through the wet curtain 2 to ensure the humidity of the indoor environment and improve the user's comfort.

[0042] Furthermore, the air cooler impeller 1 is constructed as a cross-flow impeller, which extends vertically, allowing airflow to pass through the impeller and thus increasing the airflow delivery distance and ensuring uniform airflow for a better user experience. In addition, the length of the cross-flow impeller can be adjusted according to different specifications, increasing the flexibility of the installation. The wet curtain 2 is located on the air inlet side of the air cooler impeller 1, meaning that the air cooler impeller 1 drives the airflow to flow into the air cooler assembly 100. The airflow can flow through the wet curtain 2, where it is cooled before flowing back to the air cooler impeller 1, and then being delivered to the outside of the air cooler assembly 100 by the air cooler impeller 1 to cool the environment, ensuring the reliability of airflow cooling.

[0043] In addition, the air cooler assembly 100 is equipped with a main water tank 4 and a second water tank 5. The main water tank 4 is larger in volume and can hold more water, which can reduce the number of times the user needs to add water to the air cooler assembly 100, improve the convenience of use, and thus improve the user experience. The second water tank 5 can be set close to the main water tank 4, so that the main water tank 4 can be directly connected to the second water tank 5 through the fourth water outlet 42. Alternatively, the second water tank 5 can be set away from the main water tank 4, so that the second water tank 5 can be connected to the main water tank 4 through the first pipe 42, allowing the main water tank 4 to supply water to the second water tank 5. The second water tank 5 can be equipped with insulation materials, etc., and its smaller size can reduce installation costs. The second water tank 5 is equipped with a cold source 53, which can cool the water in the second water tank 5. The smaller water volume in the second water tank 5 can increase the cooling speed of the water in the second water tank 5 by the cold source 53.

[0044] In this way, the proportion of water that absorbs cold energy and participates in the refrigeration cycle can be increased, thereby reducing the waste of cold energy in low-temperature water, improving the utilization rate of cold energy, reducing the energy consumption of the air cooler assembly 100, and increasing the cooling speed of the air cooler assembly 100 on the airflow. In addition, the main water tank 4 can supply water to the second water tank 5. The main water tank 4 is set to be larger in volume, which can reduce the total water storage in the air cooler assembly 100, thereby reducing the number of times the user needs to replenish water, improving the convenience of use, and thus improving the user experience.

[0045] Meanwhile, the air cooler assembly 100 is also equipped with a first water storage tank 6, which is located on top of the evaporative cooling pad 2. That is, the first water storage tank 6 is located above the evaporative cooling pad 2, and the evaporative cooling pad 2 is located below the first water storage tank 6. The second water tank 5 can supply water to the first water storage tank 6, and the first water storage tank 6 can supply water to the evaporative cooling pad 2. That is, the low-temperature water that has been cooled in the second water tank 5 can be transported to the first water storage tank 6, and the low-temperature water in the first water storage tank 6 can be discharged from the first water storage tank 6 under the action of gravity, and then flow to the top of the evaporative cooling pad 2 located below the first water storage tank 6. The evaporative cooling pad 2 is arranged in a vertical direction, so that the low-temperature water can flow from the top of the evaporative cooling pad 2 to the bottom of the evaporative cooling pad 2 under the action of gravity. This allows the low-temperature water to fill the evaporative cooling pad 2 only under the action of gravity, reducing the installation cost and the operating energy consumption of the air cooler assembly 100, and ensuring the reliability of use.

[0046] Furthermore, the cooling fan assembly 100 is also equipped with a second water storage tank 7, which is located at the bottom of the wet curtain 2. The top of the second water storage tank 7 can be opened towards the bottom of the wet curtain 2, so that at least part of the bottom of the wet curtain 2 can be placed in the second water storage tank 7. The low-temperature water in the second water tank 5 can flow through the first water storage tank 6 to the top of the wet curtain 2, and under the action of gravity, it flows from the bottom of the wet curtain 2 to the second water storage tank 7 for temporary storage, so that the second water storage tank 7 can collect water from the wet curtain 2. The volume of the second water storage tank 7 can be set to be smaller than that of the main water tank 4 and the second water tank 5.

[0047] In addition, the second water storage tank 7 can supply water to one of the first water storage tank 6 and the main water tank 4. That is, the water flowing from the first water storage tank 6 through the wet curtain 2 can be temporarily stored in the second water storage tank 7. When the cooling capacity of the water in the second water storage tank 7 is low, the water can flow directly into the main water tank 4. When the water in the second water storage tank 7 flows into the main water tank 4, the main water tank 4 can recycle the water, which reduces the water in the second water tank 5. When the water in the second water tank 5 is insufficient, the main water tank 4 can continue to supply water to the second water tank 5, reducing the number of times the user needs to replenish water, improving the convenience of use, and realizing the first water circulation.

[0048] The water in the second water storage tank 7 can also be transported to the first water storage tank 6. That is, the water flowing through the wet curtain 2 is temporarily stored in the second water storage tank 7. When the cooling capacity of the low-temperature water after flowing through the wet curtain 2 is still high, the low-temperature water can be circulated back into the first water storage tank 6. In this way, the cooling capacity in the low-temperature water can be reused, reducing energy consumption. It can also realize a second water circulation, which is highly flexible in setting, reduces the waste of cooling capacity, improves the utilization rate of cooling capacity, and reduces the energy consumption of the air cooler assembly 100.

[0049] In this way, when there is sufficient cooling capacity in the water flow after passing through the wet curtain 2, the water in the second water storage tank 7 can flow back into the first water storage tank 6 to complete the second water cycle. This allows for full utilization of the cooling capacity in the water flow, reducing waste and lowering the energy consumption of the air cooler assembly 100. When there is insufficient cooling capacity in the water flow after passing through the wet curtain 2, the water in the second water storage tank 7 can flow into the main water tank 4 to complete the first water cycle. This ensures the cooling effect of the air cooler assembly 100, guarantees the user experience, and improves user comfort.

[0050] Meanwhile, when the water in the second water tank 5 decreases due to evaporation or other reasons, the main water tank 4 can supply water to the second water tank 5, thereby ensuring the reliability of the second water tank 5 and reducing the number of times users need to replenish water, thus improving the user experience. Furthermore, the cold source 53 is located in the second water tank 5, and low-temperature water is supplied directly from the second water tank 5 to the wet curtain 2, which can improve the cooling effect of the evaporative cooling fan assembly 100, ensure the user experience, and improve user comfort.

[0051] In actual use, the water in the air cooler assembly 100 can be replaced with refrigerant, etc., and the cold source 53 can be set as ice crystals, etc. Ice crystals are a special kind of gel or crystal that can cool water or refrigerant, etc., with low setup cost and improved environmental friendliness.

[0052] According to an embodiment of the present invention, the air cooler assembly 100, by circulating water between the main water tank 4, the second water tank 5, the first water storage tank 6, and the second water storage tank 7 in a first water circulation and between the first water storage tank 6 and the second water storage tank 7 in a second water circulation, can increase the proportion of water in the second water tank 5 that has absorbed cold energy participating in the refrigeration cycle. This can reduce the waste of cold energy, improve the utilization rate of cold energy, reduce the energy consumption of the air cooler assembly 100, and improve the cooling effect of the air cooler assembly 100, ensuring the user experience, improving user comfort, and providing better performance and wider applicability.

[0053] In some embodiments, the second water tank 5 is located above the wet curtain 2, and the first water storage tank 6 is located between the top of the wet curtain 2 and the second water tank 5. The second water tank 5 is provided with a first water outlet 51 that supplies water to the first water storage tank 6, and the first water storage tank 6 is provided with a second water outlet 61 that supplies water to the top of the wet curtain 2.

[0054] Specifically, the second water tank 5 is located above the wet curtain 2 and is used to supply water to the first water storage tank 6. The second water tank 5 is provided with a first water outlet 51, which is open to the first water storage tank 6. That is, the first water outlet 51 can be located below the second water tank 5. The water in the second water tank 5 that has been cooled by the cold source 53 can be discharged through the first water outlet 51 under the action of gravity. The discharged low-temperature water can flow to the top of the wet curtain 2 under the action of gravity. The low-temperature water in the wet curtain 2 can flow from the top to the bottom of the wet curtain 2 under the action of gravity, so that the entire wet curtain 2 can be filled with low-temperature water. This allows the airflow flowing through the wet curtain 2 to be cooled, ensuring the reliability of airflow cooling. Furthermore, by placing the second water tank 5 above the wet curtain 2, the low-temperature water can fill the wet curtain 2 only under the action of gravity, reducing the installation cost and the operating energy consumption of the cooling fan assembly 100, while ensuring the reliability of use.

[0055] In addition, such as Figures 1-2 As shown, the first water storage tank 6 is vertically positioned between the second water tank 5 and the wet curtain 2, and the first water storage tank 6 is also provided with a second water outlet 61. The second water outlet 61 is located at the bottom of the first water storage tank 6, so that the low-temperature water flowing into the first water storage tank 6 through the first water outlet 51 can flow to the bottom of the first water storage tank 6 under the action of gravity, and the low-temperature water in the first water storage tank 6 can be discharged from the first water storage tank 6 through the second water outlet 61 under the action of gravity.

[0056] Furthermore, the second water outlet 61 is open towards the top of the wet curtain 2, allowing the low-temperature water in the first water storage tank 6 to flow through the second water outlet 61 towards the top of the wet curtain 2. Since the volume of the first water storage tank 6 is smaller than the volume of the second water tank 5, some of the low-temperature water in the second water tank 5 can flow into the first water storage tank 6 for temporary storage, and then supply water to the wet curtain 2 through the first water storage tank 6. This allows most of the water in the second water tank 5 to be kept warm in the second water tank 5, with only a portion of the low-temperature water participating in the refrigeration cycle, thereby reducing the waste of cooling capacity, improving the utilization rate of cooling capacity, and reducing the energy consumption of the evaporator assembly 100.

[0057] In some embodiments, a second water valve 511 is provided at the first water outlet 51, and the second water valve 511 is used to selectively open or close the first water outlet 51.

[0058] Specifically, the second water tank 5 is provided with a first water outlet 51, and the first water outlet 51 is located at the bottom of the second water tank 5, with the first water outlet 51 open towards the first water storage tank 6, so that the low-temperature water in the second water tank 5 can be transported to the first water storage tank 6, and as... Figure 1As shown, a second water valve 511 is provided at the first water outlet 51. The second water valve 511 can be used to selectively open or close the first water outlet 51. That is, when the second water valve 511 is opened, the first water outlet 51 is open, and the low temperature water in the second water tank 5 can flow into the first water storage tank 6 through the first water outlet 51. When the second water valve 511 is closed, the first water outlet 51 is closed to cut off the connection between the second water tank 5 and the first water storage tank 6, thereby stopping the second water tank 5 from supplying water to the first water storage tank 6.

[0059] Furthermore, a cold source 53 is provided in the second water tank 5. When the air cooler assembly 100 is running, the second water valve 511 is closed, the main water tank 4 supplies water to the second water tank 5, and the cold source 53 can cool the water in the second water tank 5 to the required temperature. At this time, the second water valve 511 can be opened, so that the low temperature water can flow through the first water storage tank 6 to the wet curtain 2 under the action of gravity to cool the airflow flowing through the wet curtain 2. When the amount of cold water flowing into the second water storage tank 7 is large, the water flow in the second water storage tank 7 can be returned to the first water storage tank 6 to ensure that the air supply temperature meets the user's needs and improve the utilization rate of cold energy, thereby reducing the operating energy consumption of the air cooler assembly 100 and improving the user experience.

[0060] In some embodiments, a first water pump 72 is provided in the second water storage tank 7, and the first water pump 72 is used to pump water from the second water storage tank 7 to the first water storage tank 6.

[0061] Specifically, the second water storage tank 7 is located at the bottom of the evaporative cooling pad 2. The low-temperature water in the evaporative cooling pad 2 cools the airflow and then flows into the second water storage tank 7 for temporary storage. Figures 1-2 As shown, a first water pump 72 is installed in the second water storage tank 7, and a second pipeline 62 connected to the second water storage tank 7 is installed thereto. The first water pump 72 can transport the low-temperature water in the second water storage tank 7 to the second pipeline 62.

[0062] Furthermore, such as Figure 1 As shown, one end of the second pipe 62 is connected to the second water storage tank 7, and the other end of the second pipe 62 is connected to the first water storage tank 6. The first water pump 72 can transport the low-temperature water in the second water storage tank 7 to the second pipe 62, and then transport the low-temperature water to the first water storage tank 6 through the second pipe 62. When the low-temperature water in the first water storage tank 6 flows to the wet curtain 2, the low-temperature water has a large amount of cooling capacity, and only a portion of the cooling capacity can be used to cool the airflow. This results in the low-temperature water flowing to the second water storage tank 7 still having some cooling capacity. This low-temperature water can flow back to the first water storage tank 6 through the second pipe 62, and then flow to the wet curtain 2 again, so as to make full use of the cooling capacity of the low-temperature water, reduce the waste of cooling capacity, and improve the utilization rate of cooling capacity.

[0063] In some embodiments, the second water storage tank 7 is provided with a third water outlet 71, which is used to supply water to the main water tank 4.

[0064] Specifically, the water flowing through the wet curtain 2 can be temporarily stored in the second water storage tank 7, and the second water storage tank 7 is provided with a third water outlet 71. The third water outlet 71 is located at the bottom of the second water storage tank 7. The water in the wet curtain 2 can flow into the second water storage tank 7, and under the action of gravity, the low temperature water can be temporarily stored at the bottom of the second water storage tank 7. The third water outlet 71 is provided at the bottom of the second water storage tank 7, so that the water in the second water storage tank 7 can be discharged from the second water storage tank 7 through the third water outlet 71 under the action of gravity. That is, when the cooling capacity of the water flowing through the wet curtain 2 is small, the water can be directly discharged from the second water circulation to ensure the cooling effect of the air cooler assembly 100.

[0065] Furthermore, the second water storage tank 7 is positioned above the main water tank 4, and as... Figure 1 As shown, the third water outlet 71 can be opened towards the main water tank 4, so that the low-temperature water in the second water storage tank 7 can be supplied to the main water tank 4 through the third water outlet 71. When the low-temperature water in the wet curtain 2 cools the airflow, its internal cooling capacity decreases, and then flows into the second water storage tank 7. When the water in the second water storage tank 7 is at the same temperature as the water in the main water tank 4, that is, when the cooling capacity of the water is too low, this part of the water can be directly supplied to the main water tank 4 through the third water outlet 71, avoiding this part of the water from continuing to undergo the second water circulation, which would affect the cooling effect of the air cooler assembly 100. In addition, the water can be recycled and reused, reducing the number of water replenishments, improving the environmental friendliness and ease of use, and improving the user experience.

[0066] In some embodiments, the third water outlet 71 is provided with a first water valve 711, and the second water storage tank 7 is provided with a temperature detection element. The first water valve 711 is used to control the third water outlet 71 to selectively open or close according to the temperature detection value of the temperature detection element.

[0067] Specifically, the bottom of the second water storage tank 7 is provided with a third water outlet 71, so that the water in the second water storage tank 7 can be discharged into the main water tank 4 through the third water outlet 71, and as... Figure 1 As shown, the third outlet 71 is equipped with a first water valve 711. The first water valve 711 is used to selectively open or close the third outlet 71. That is, when the first water valve 711 is open, the third outlet 71 is open, and the water in the second water storage tank 7 can be discharged into the main water tank 4 through the third outlet 71. When the first water valve 711 is closed, the third outlet 71 can be closed, thereby cutting off the connection between the second water storage tank 7 and the main water tank 4.

[0068] Furthermore, a temperature detection device can be installed in the second water storage tank 7. The temperature detection device can detect the water temperature in the second water storage tank 7, thereby detecting the cooling capacity of the water in the second water storage tank 7. When the temperature detection device detects that the water temporarily stored in the second water storage tank 7 is low-temperature water, that is, the cooling capacity of the low-temperature water is sufficient, the first water valve 711 can be controlled to close, that is, the third water outlet 71 can be closed. The second water storage tank 7 can be connected to the first water storage tank 6 through the second pipeline 62, so that the low-temperature water in the second water storage tank 7 can be transported to the second pipeline 62 through the first water pump 72, and then transported to the first water storage tank 6. This allows the low-temperature water to flow again to the wet curtain 2 to cool the airflow, forming a second water circulation. The water flow path in this circulation is shorter, which can reduce the loss of cooling capacity and reduce the operating energy consumption.

[0069] Furthermore, a third pipe 73 is provided below the second water storage tank 7. The third pipe 73 is configured to connect with the third water outlet 71 and extends towards the main water tank 4. When the temperature detection device detects that the water temporarily stored in the second water storage tank 7 is at room temperature, that is, the amount of cold water in the water is small, the first water valve 711 can be controlled to open, that is, the third water outlet 71 can be opened, and the second water storage tank 7 can be connected to the main water tank 4 through the third pipe 73, so that the room temperature water in the second water storage tank 7 can flow back to the main water tank 4 under the action of gravity, so as to recycle the water.

[0070] The third pipe 73 extends into the main water tank 4 to ensure that the water in the second water storage tank 7 can flow accurately into the main water tank 4, preventing water from flowing into the rest of the cooling fan assembly 100 and ensuring the operational reliability of the cooling fan assembly 100.

[0071] In some embodiments, the second water tank 5 is located at the bottom of the wet curtain 2.

[0072] Specifically, such as Figures 1-3 As shown, the second water storage tank 7 is located at the bottom of the wet curtain 2. The top of the second water storage tank 7 can be opened towards the bottom of the wet curtain 2, so that at least part of the bottom of the wet curtain 2 can be placed in the second water storage tank 7. The low-temperature water in the second water tank 5 can flow to the top of the wet curtain 2 through the first water storage tank 6 under the action of gravity. Under the action of gravity, the low-temperature water can flow down the wet curtain 2 from the top of the wet curtain 2 until it flows to the bottom of the wet curtain 2. The bottom of the wet curtain 2 is placed in the second water storage tank 7, so that the low-temperature water flowing to the bottom of the wet curtain 2 can flow to the second water storage tank 7 for temporary storage under the action of gravity. There is no need to set up an extra water flow delivery structure, which can reduce the operating energy consumption of the cooling fan assembly 100 and ensure the user experience.

[0073] In some embodiments, the second water tank 5 is located at the bottom of the main water tank 4, and the bottom of the second water tank 5 is also provided with a third water storage tank 8, and the second water tank 5 supplies water to the first water storage tank 6 through a third water pump 81 in the third water storage tank 8.

[0074] Specifically, such as Figure 3 As shown, the second water tank 5 can also be set at the bottom of the main water tank, that is, both the second water tank 5 and the main water tank 4 can be installed below the wet curtain 2. The main water tank 4 can be provided with a fourth water outlet 43, which is set at the bottom of the main water tank 4 and connected to the second water tank 5, so that the water in the main water tank 4 can flow into the second water tank 5 under the action of gravity, without the need to set up an extra water flow delivery structure, which can reduce the operating energy consumption of the cooling fan assembly 100.

[0075] Furthermore, a third water storage tank 8 is provided at the bottom of the second water tank 5. The third water storage tank 8 is openable upwards, and the lower part of the second water tank 5 can be placed inside the third water storage tank 8. The first water outlet 51 of the second water tank 5 faces the third water storage tank 8. When the first water outlet 51 is open, the second water tank 5 can deliver low-temperature water into the third water storage tank 8. A third water pump 81 is provided inside the third water storage tank 8. The third water pump 81 can be connected to the first pipeline 42, so that the third water pump 81 can deliver the low-temperature water in the third water storage tank 8 to the first pipeline 42, and then to the first water storage tank 6, so that the water in the first water storage tank 6 can flow through the wet curtain 2, thereby cooling the airflow and ensuring reliable use.

[0076] In addition, in actual installation, both the second water tank 5 and the main water tank 4 can be installed below the wet curtain 2, and the second water tank 5 can be set above or to one side of the main water tank 4. In this case, a water pump or other water conveying structure needs to be installed inside the main water tank 4 or at the connecting pipe between the main water tank 4 and the second water tank 5 to ensure the reliability of the main water tank 4 supplying water to the second water tank 5.

[0077] In some embodiments, the main water tank 4 is located at the bottom of the wet curtain 2 and is configured to open toward the wet curtain 2.

[0078] Specifically, the main water tank 4 is located at the bottom of the wet curtain 2. The main water tank 4 can supply water to the second water tank 5. The water in the second water tank 5 can flow through the wet curtain 2 to the second water storage tank 7. The water in the second water storage tank 7 can flow back into the main water tank 4 through the third pipe 73. The top of the main water tank 4 can be set to be open towards the wet curtain 2. The second water storage tank 7 is located between the wet curtain 2 and the main water tank 4, that is, the main water tank 4 can be open towards the second water storage tank 7, so that the water in the second water storage tank 7 can flow into the main water tank 4.

[0079] And such as Figures 1-2As shown, the main water tank 4 has a large opening, and the vertical projections of the first water storage tank 6, the wet curtain 2, and the second water storage tank 7 are all aligned with the opening of the main water tank 4. This ensures that the water overflowing from the first water storage tank 6, the wet curtain 2, and the second water storage tank 7 can flow into the main water tank 4 under the action of gravity, preventing water from flowing to other parts of the cooling fan assembly 100, thus ensuring the reliability and operational stability of the cooling fan assembly 100.

[0080] In some other embodiments, a second water pump 41 is provided in the main water tank 4, which is used to pump water from the main water tank 4 to the second water tank 5.

[0081] Specifically, the main water tank 4 and the second water tank 5 can be connected through the first pipe 42, so that the main water tank 4 can supply water to the second water tank 5, and so on. Figures 1-2 As shown, a second water pump 41 is installed in the main water tank 4. The second water pump 41 is used to transport water in the main water tank 4 to the second water tank 5. That is, when the second water pump 41 is running, the water in the main water tank 4 can be transported to the first pipeline 42 through the second water pump 41, and then transported to the second water tank 5 through the first pipeline 42. When the air cooler assembly 100 is initially running and when the water volume in the second water tank 5 decreases to the minimum standard, the second water pump 41 can be turned on to supply water from the main water tank 4 to the second water tank 5, so as to ensure the reliability of the operation of the air cooler assembly 100.

[0082] In some embodiments, the cold source 53 is constructed as ice crystals; or, the cold source 53 is constructed as a cooling semiconductor connected to a cooling system.

[0083] Specifically, a cold source 53 is installed inside the second water tank 5, such as... Figures 1-2 As shown, the cold source 53 can be set as ice crystals. Ice crystals are a special gel or crystal that can cool the water in the second water tank 5. The top of the second water tank 5 is removable, so that when the ice crystals in the second water tank 5 are depleted, the user can open the top cover of the second water tank 5 to replenish the ice crystals, ensuring the reliable operation of the cooling fan assembly 100; or, as... Figure 2 As shown, the cold source 53 can also be configured as a cooling semiconductor connected to the refrigeration system, which can automatically cool the water in the second water tank 5. The temperature is electrically controlled, improving accuracy and automation. Furthermore, as shown... Figure 3 As shown, the second water tank 5 can be configured as a tank with an electronic ice chamber, which can meet different production needs and improve the flexibility of the setup.

[0084] In some embodiments, the second water tank 4 is provided with a vent 52.

[0085] Specifically, such as Figures 1-3As shown, the second water tank 5 is also provided with a vent 52. The vent 52 can be set at the top of the second water tank 4, so that the vent 52 can discharge the gas in the second water tank 5, ensuring the reliability of the water supply to the second water tank 5. Setting the vent 52 at the top of the second water tank 5 can prevent the water in the second water tank 5 from overflowing from the vent 52, so as to ensure the reliability of the operation of the cooling fan assembly 100. In addition, the user can also add water to the second water tank 5 through the vent 52, improving the convenience of use.

[0086] In some embodiments, the main water tank 4 and the second water tank 5 are both located at the bottom of the wet curtain 2 and stacked in the vertical direction, and the position of the vent 52 is higher than that of the main water tank 4; or, the second water tank 5 is located at the top of the cooling fan impeller 1.

[0087] Specifically, such as Figure 3 As shown, both the main water tank 4 and the second water tank 5 are located at the bottom of the wet curtain 2 and are stacked vertically. That is, in the vertical direction, the second water tank 5 can be positioned above or below the main water tank 4. The vent 52 on the upper part of the second water tank 5 must be positioned higher than the main water tank 4. Specifically, when the second water tank 5 is positioned above the main water tank 4, the vent 52 of the second water tank 5 must be positioned higher than the main water tank 4. When the second water tank 5 is positioned below the main water tank 4, as shown... Figure 3 As shown, the upper part of the second water tank 5 can be provided with an upwardly extending exhaust pipe, and the end of the exhaust pipe away from the second water tank 5 forms an exhaust hole 52, so that the position of the exhaust hole 52 is also higher than that of the main water tank 4, thereby ensuring that the water in the second water tank 5 will not overflow from the exhaust hole 52, so as to ensure the reliability of the operation of the cooling fan assembly 100.

[0088] In addition, the second water tank 5 can also be installed on the top of the fan impeller 1. The first outlet 51 of the second water tank 5 can be connected to the first water storage tank 6 through pipes, etc., to supply water to the first water storage tank 6, thereby improving the flexibility of the installation.

[0089] like Figure 1 and Figure 4 As shown, the complete operation process of the air cooler assembly 100 is as follows:

[0090] Specifically, when the cooling fan assembly 100 starts, the second water valve 511 of the first water outlet 51 is closed, and the second water pump 41 in the main water tank 4 starts to supply water to the second water tank 5. When the second water tank 5 reaches the set water volume or is full, the second water pump 41 stops running to stop the main water tank 4 from filling the second water tank 5. The water volume in the second water tank 5 can be detected by adding a float-type detection switch or other liquid level detection device to the second water tank 5. When the liquid level reaches the preset value, a signal is sent to the control system, and the control system controls the main water tank 4 to stop supplying water. The accuracy is high, and the time required for the second water tank 5 to be filled or reach the preset water level can be calculated based on the flow rate of the second water pump 41. When the time is reached, the main water tank 4 stops supplying water. The setup cost is low.

[0091] Furthermore, the water in the second water tank 5 can be cooled by the cold source 53. The cold source 53 can be set as ice crystals or a refrigeration semiconductor connected to the refrigeration system. When the cold source 53 is a refrigeration semiconductor connected to the refrigeration system, the refrigeration system can be turned on after the second water tank 5 is filled with water or reaches the preset water level. When the cold source 53 is ice crystals, the user can be prompted to add ice crystals after the second water tank 5 is filled with water or reaches the preset water level. When the water temperature in the second water tank 5 drops to the preset water temperature, the first water valve 711 of the third water outlet 71 closes and the second water valve 511 of the first water outlet 51 opens. If the water supply time of the second water tank 5 is longer than the preset time, the second water valve 511 closes and the first water pump 72 in the second water storage tank 7 is turned on, so that the low temperature water can circulate between the first water storage tank 6, the wet curtain 2 and the second water storage tank 7, which can reduce the loss of cold energy, improve the refrigeration effect and improve the user comfort.

[0092] Furthermore, when the temperature of the low-temperature water is greater than or equal to the temperature of the water in the main water tank 4, the first water valve 711 of the third outlet 71 can be opened to allow the water in the second water storage tank 7 to flow to the main water tank 4. At this time, the second water valve 511 of the first outlet 51 is closed. After the water is discharged, the second water valve 511 of the first outlet 51 can be opened to continue discharging low-temperature water into the first water storage tank 6 to repeat the second water cycle, i.e., internal circulation. When the water in the second water tank 5 is depleted or reaches the preset water level, the second water pump 41 of the main water tank 4 is turned on, allowing the main water tank 4 to fill the second water tank 5 with water until the water level in the second water tank 5 reaches the preset water level or is full, thus completing the first water cycle, i.e., external circulation. This avoids wasting cooling capacity, reduces operating costs, and improves the user experience, ensuring user comfort.

[0093] like Figure 2 and Figure 5 As shown, the complete operation process of the air cooler assembly 100 is as follows:

[0094] Specifically, when the air cooler assembly 100 starts, if the cold source 53 in the second water tank 5 is a refrigeration semiconductor connected to the refrigeration system, the first water outlet 51 is equipped with a second water valve 511, which is in a closed state, so that the water temperature in the second water tank 5 can be discharged only after it drops to the set temperature, thus ensuring the cooling effect. If the cold source 53 is ice crystals, a second water valve 511 can be installed at the first water outlet 51, or the second water valve 511 can be omitted. Users can add ice crystals to the second water tank 5 before the air cooler assembly 100 starts.

[0095] The second water pump 41 in the main water tank 4 is turned on to supply water to the second water tank 5. Once the second water tank 5 reaches the set water volume or is full, the second water pump 41 stops running to stop the main water tank 4 from filling the second water tank 5. The water volume in the second water tank 5 can be detected by adding a float-type detection switch or other liquid level detection device to the second water tank 5. When the liquid level reaches the preset value, a signal is sent to the control system, which controls the main water tank 4 to stop supplying water. This method is highly accurate and can also calculate the time required for the second water tank 5 to fill with water or reach the preset water level based on the flow rate of the second water pump 41. Once the time is reached, the main water tank 4 stops supplying water. This method has low setup costs.

[0096] Furthermore, the low-temperature water in the second water tank 5 can flow through the first outlet 51 to the first water storage tank 6, and then be evenly distributed onto the wet curtain 2 through the second outlet 61 of the first water storage tank 6. The water then flows from the wet curtain 2 to the second water storage tank 7. At this time, the first water pump 72 of the second water storage tank 7 is running, so that the water in the second water storage tank 7 can flow into the first water storage tank 6. This allows the low-temperature water to circulate between the first water storage tank 6, the wet curtain 2, and the second water storage tank 7, which can reduce the loss of cooling capacity, improve the cooling effect, and improve the user comfort, until the water in the main water tank 4 is exhausted.

[0097] When the main water tank 4 is low on water, the second water tank 5 may be full, meaning the cooling fan assembly 100 can still run for a period of time. If the water in the main water tank 4 is not replenished, the second water tank 5 will run out of water and report that the second water tank 5 is low on water. The cooling fan assembly 100 will then be unable to work properly, reminding the user to add water in time.

[0098] like Figure 3 As shown, the complete operation process of the air cooler assembly 100 is as follows:

[0099] Specifically, when the cooling fan assembly 100 starts, the fourth outlet 43 of the main water tank 4 opens to supply water to the second water tank 5. Once the second water tank 5 reaches the set water volume or is full, the fourth outlet 43 closes. The water volume in the second water tank 5 can be monitored by adding a float-type detection switch or other liquid level detection device to the second water tank 5. When the liquid level reaches the preset value, a signal is sent to the control system, which then controls the fourth outlet 43 to close. The second water tank 5 is equipped with an electronic ice tank, and the first outlet 51 is equipped with a second water valve 511, which is in a closed state. This ensures that the water temperature in the second water tank 5 drops to the set temperature before being discharged, thus guaranteeing the cooling effect.

[0100] Furthermore, the low-temperature water in the second water tank 5 can flow to the third water storage tank 8 through the first water outlet 51. The third water storage tank 8 is equipped with a third water pump 81, which can transport the low-temperature water to the first water storage tank 6. Then, it can be evenly distributed onto the wet curtain 2 through the second water outlet 61 of the first water storage tank 6, and then flow from the wet curtain 2 to the second water storage tank 7. At this time, the first water pump 72 of the second water storage tank 7 is running, so that the water in the second water storage tank 7 can flow into the first water storage tank 6. This allows the low-temperature water to circulate between the first water storage tank 6, the wet curtain 2, and the second water storage tank 7, which can reduce the loss of cold energy, improve the cooling effect, and improve the user comfort.

[0101] like Figure 6 As shown, the complete operation process of the air cooler assembly 100 is as follows:

[0102] Specifically, when the cooling fan assembly 100 starts, the second water valve 511 of the first water outlet 51 is closed, and the second water pump 41 in the main water tank 4 starts to supply water to the second water tank 5. When the second water tank 5 reaches the set water volume or is full, the second water pump 41 stops running to stop the main water tank 4 from filling the second water tank 5. The water volume in the second water tank 5 can be detected by adding a float-type detection switch or other liquid level detection device to the second water tank 5. When the liquid level reaches the preset value, a signal is sent to the control system, and the control system controls the main water tank 4 to stop supplying water. The accuracy is high, and the time required for the second water tank 5 to be filled or reach the preset water level can be calculated based on the flow rate of the second water pump 41. When the time is reached, the main water tank 4 stops supplying water. The setup cost is low.

[0103] Furthermore, the water in the second water tank 5 can be cooled by the cold source 53. The cold source 53 can be set as ice crystals or a cooling semiconductor connected to the refrigeration system. When the cold source 53 is a cooling semiconductor connected to the refrigeration system, the refrigeration system can be turned on after the second water tank 5 is filled with water or reaches the preset water level. When the cold source 53 is ice crystals, the user can be prompted to add ice crystals after the second water tank 5 is filled with water or reaches the preset water level. When the water temperature in the second water tank 5 drops to the preset water temperature, the liquid level detection device in the first water tank 6 or the second water tank 7 can be used to determine whether there is water in the first water tank 6 or the second water tank 7, and thus determine whether the air cooler assembly 100 is being started for the first time.

[0104] When the air cooler assembly 100 is not being started for the first time, the second water valve 511 should be kept closed and the first water valve 711 of the third outlet 71 should be opened so that the water in the second water tank 7 can flow to the main water tank 4. This will allow the stagnant water in the second water circulation to be discharged to the main water tank 4, preventing the water in the first water tank 6 and the second water tank 7 from overflowing when the second water tank 5 replenishes water to the second water circulation, thus ensuring the reliability of the air cooler assembly 100.

[0105] When the cooling fan assembly 100 is started for the first time, the first water valve 711 of the third water outlet 71 can be closed and the second water valve 511 of the first water outlet 51 can be opened. When the water supply time of the second water tank 5 is longer than the preset time, the second water valve 511 is closed and the first water pump 72 in the second water storage tank 7 is turned on, so that the low temperature water can circulate between the first water storage tank 6, the wet curtain 2 and the second water storage tank 7, which can reduce the loss of cold energy, improve the cooling effect and improve the comfort of use.

[0106] Furthermore, when the temperature of the low-temperature water is greater than or equal to the temperature of the water in the main water tank 4, the first water valve 711 of the third outlet 71 can be opened to allow the water in the second water storage tank 7 to flow to the main water tank 4. At this time, the second water valve 511 of the first outlet 51 is closed. After the water is discharged, the second water valve 511 of the first outlet 51 can be opened to continue discharging low-temperature water into the first water storage tank 6 to repeat the second water cycle, i.e., internal circulation. When the water in the second water tank 5 is depleted or reaches the preset water level, the second water pump 41 of the main water tank 4 is turned on, allowing the main water tank 4 to fill the second water tank 5 with water until the water level in the second water tank 5 reaches the preset water level or is full, thus completing the first water cycle, i.e., external circulation. This avoids wasting cooling capacity, reduces operating costs, and improves the user experience, ensuring user comfort.

[0107] This utility model also proposes an air conditioner.

[0108] The air conditioner according to the present utility model includes a cooling fan assembly 100 of any of the above-mentioned components, wherein the air conditioner may be configured as a cooling fan or the like.

[0109] According to the embodiment of this utility model, the air conditioner is provided with a cooling fan assembly 100. The cooling fan assembly 100 has a second water tank 5 above the wet curtain 2, and the cold source 53 is placed in the second water tank 5. This can increase the proportion of water participating in the refrigeration cycle after absorbing cold energy, thereby reducing the waste of cold energy, improving the utilization rate of cold energy, and reducing the energy consumption of the cooling fan assembly 100. Furthermore, placing the second water tank 5 above the wet curtain 2 can shorten the length of the water transportation process after absorbing cold energy, thereby reducing the loss of cold energy during transportation. This improves the cooling effect of the cooling fan assembly 100, ensures the user experience, improves the comfort of use, and has a better performance and wider applicability.
