Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to an air cooler assembly. Background Technology

[0002] With the improvement of people's living standards, air purifiers have become an indispensable appliance in daily life. Current air purifiers typically use a water pump to draw water from a bottom tank to a top temporary chamber. A drain hole at the bottom of the top temporary chamber allows water to flow onto a cooling pad. The fan draws air in from the side of the cooling pad, and the air passes through the cooling pad, completing the heat exchange between the air and the water. To achieve better cooling, ice crystals are usually added to the bottom tank to lower the water temperature. However, the bottom tank is an open tank. After adding ice crystals, the ice crystals quickly exchange heat with the surrounding water and air, and the cold water is also quickly displaced by the surrounding air, resulting in rapid loss of cooling capacity. The cold water quickly becomes room temperature, leading to a decrease in cooling effect and room for improvement. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The following is for reference. Figures 1-4 The cooling fan assembly 100 according to the present invention can cool the water in the second water tank 4 and reduce the heat exchange between the low-temperature water after absorbing cold energy and the external environment, thereby effectively improving the cooling effect of the cooling fan assembly 100, ensuring user experience, improving user comfort, reducing the waste of cold energy in the low-temperature water, improving the utilization rate of cold energy, and reducing the energy consumption of the cooling fan assembly 100.

[0032] like Figure 1 As 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 3, and a second water tank 4.

[0033] The wet curtain 2 and the cold air impeller 1 are distributed along the airflow direction of the cold air impeller 1; the main water tank 3 is connected to the second water tank 4. The main water tank 3 is used to supply water to the second water tank 4. The second water tank 4 is located below the wet curtain 2. The second water tank 4 is equipped with a cooling component. The second water tank 4 supplies water to the top of the wet curtain 2 through the first connecting pipe 42.

[0034] Specifically, a evaporative air cooler, also known as an air conditioning fan, is a type of air conditioner. It is equipped with a cooling component that cools the water. The airflow delivered by the evaporative air cooler can exchange heat with the cooled water, allowing the evaporative air cooler to blow out cool air, thereby achieving a cooling effect. In addition, evaporative air coolers are energy-saving and environmentally friendly, easy to move and carry, can increase indoor humidity, and ensure a good user experience.

[0035] The air cooler assembly 100 includes an air cooler impeller 1, and a drive motor 8 is correspondingly mounted on the air cooler impeller 1. The output shaft of the drive motor 8 is connected to the air cooler impeller 1. When the drive motor 8 runs, it transmits power to the air cooler impeller 1 through the output shaft, causing the air cooler impeller 1 to rotate. When the air cooler impeller 1 rotates, it drives the surrounding air to circulate. A motor mounting bracket 81 is provided inside the air cooler assembly 100, and the drive motor 8 is fixedly installed in the motor mounting bracket 81, ensuring the reliable operation of the drive motor 8 and the air cooler impeller 1. Figure 4 As shown, the air cooler assembly 100 is provided with an air outlet 9, which is used to connect the interior of the air cooler assembly 100 with the exterior. The air outlet 9 is positioned directly opposite the air cooler impeller 1, so that the air cooler impeller 1 can drive airflow to be sent out from the air outlet 9, thereby realizing the cooling function of the air cooler assembly 100.

[0036] Furthermore, the air cooler assembly 100 is also equipped with a wet curtain 2. Low-temperature water cooled by the cooling components 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, so that the airflow driven by the air cooler impeller 1 can flow through the wet curtain 2. In this way, 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.

[0037] In addition, the air cooler assembly 100 is equipped with a main water tank 3 and a second water tank 4. The main water tank 3 is connected to the second water tank 4 and is used to supply water to the second water tank 4. The main water tank 3 has a larger 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. Moreover, the second water tank 4 is equipped with a cooling component to cool the water in the second water tank 4. The second water tank 4 can be made of heat-insulating material to reduce the heat exchange between the low-temperature water after absorbing cold energy and the external environment, thereby effectively improving the cooling effect of the air cooler assembly 100, reducing the waste of cold energy in the low-temperature water, improving the utilization rate of cold energy, and reducing the energy consumption of the air cooler assembly 100.

[0038] It should be noted that the cooling component can be a cold source 41, which can be set as ice crystals, etc. Ice crystals are a special kind of gel or crystal that can cool water. This reduces the installation cost and improves the environmental friendliness of the product. Alternatively, the cooling component can be an active cooling system such as a semiconductor or compressor. The water temperature can be accurately controlled by the active cooling system. Furthermore, the second water tank 4 has a smaller volume, which can reduce the amount of insulation material used, lower the installation cost, and increase the cooling speed of the water in the second water tank 4 by the cooling component. This, in turn, can increase the cooling speed of the airflow of the 100-air cooling fan assembly, thereby improving the user experience.

[0039] Meanwhile, the second water tank 4 is located below the wet curtain 2, and the second water tank 4 supplies water to the top of the wet curtain 2 through the first connecting pipe 42. That is, the first connecting pipe 42 can transport the low-temperature water in the second water tank 4 to the top of the wet curtain 2, so that the low-temperature water can flow from the top of the wet curtain 2 to the bottom of the wet curtain 2 under the action of gravity, so that the entire wet curtain 2 is fully soaked with low-temperature water, so that the airflow flowing through the wet curtain 2 can be cooled, ensuring the reliability of cooling the airflow.

[0040] Furthermore, after the air cooler assembly 100 has been working for a period of time, that is, after the water in the second water tank 4 has decreased, the main water tank 3 can supply water to the second water tank 4, thereby ensuring the reliability of the second water tank 4. Moreover, since the cooling component is located in the second water tank 4, low-temperature water can be supplied directly from the second water tank 4 to the wet curtain 2, which can reduce the loss of cooling capacity, improve the cooling effect of the air cooler assembly 100, ensure the user experience, and improve the comfort of use.

[0041] It should be noted that the low-temperature water in the second water tank 4 needs to flow upward along the first connecting pipe 42 to the top of the wet curtain 2. A water pump can be installed in the second water tank 4 or on the first connecting pipe 42 to ensure the reliability of the low-temperature water flowing upward to the top of the wet curtain 2.

[0042] According to the embodiment of the present utility model, the cooling fan assembly 100, by setting a second water tank 4 and setting a cooling component in the second water tank 4, can cool the water in the second water tank 4, and can reduce the heat exchange between the low-temperature water after absorbing cold energy and the external environment, thereby effectively improving the cooling effect of the cooling fan assembly 100, ensuring the user experience, improving the comfort of use, reducing the waste of cold energy in the low-temperature water, improving the utilization rate of cold energy, and reducing the energy consumption of the cooling fan assembly 100.

[0043] In some embodiments, the main water tank 3 is located above the second water tank 4.

[0044] Specifically, the main water tank 3 is used to supply water to the second water tank 4. By placing the main water tank 3 above the second water tank 4, the main water tank 3 and the second water tank 4 can be set vertically, so that the setting height of the main water tank 3 is higher than that of the second water tank 4. This allows the water in the main water tank 3 to flow into the second water tank 4 under the action of gravity. There is no need to set up other components to drive the water in the main water tank 3 to flow into the second water tank 4, which can reduce the water supply cost from the main water tank 3 to the second water tank 4, and thus help to reduce the overall setting cost of the air cooler assembly 100.

[0045] In some embodiments, the main water tank 3 and the second water tank 4 are connected by a connecting pipe 31, and a control valve is provided in the connecting pipe 31 to control the opening and closing of the connecting pipe 31.

[0046] Specifically, the main water tank 3 is used to supply water to the second water tank 4. The main water tank 3 and the second water tank 4 are connected by a connecting pipe 31, so that the water in the main water tank 3 can flow to the second water tank 4 along the connecting pipe 31. A control valve is installed in the connecting pipe 31 to control the opening and closing of the connecting pipe 31. That is, the connection or disconnection between the main water tank 3 and the second water tank 4 can be controlled by the control valve. When the control valve is open, the connecting pipe 31 is open, the main water tank 3 and the second water tank 4 are connected, and the main water tank 3 can supply water to the second water tank 4. When the control valve is closed, the connecting pipe 31 is disconnected, the main water tank 3 and the second water tank 4 are disconnected, and the main water tank 3 will not supply water to the second water tank 4.

[0047] Therefore, when the water level in the second water tank 4 is sufficient, the control valve can be closed to prevent the main water tank 3 from supplying too much water to the second water tank 4, which would cause the water in the second water tank 4 to overflow. This also prevents the water in the second water tank 4 from exchanging heat with the water in the main water tank 3, thus ensuring the cooling effect of the refrigeration components on the water in the second water tank 4. When the water level in the second water tank 4 is low, the control valve can be opened to supply water to the second water tank 4 through the main water tank 3, ensuring that the water level in the second water tank 4 is sufficient, thus ensuring the reliable operation of the cooling fan assembly 100.

[0048] It should also be noted that when using the active cooling system to cool the water in the second water tank 4, the active cooling system can be set between the main water tank 3 and the second water tank 4, so that the water in the main water tank 3 can first enter the active cooling system, be cooled by the active cooling system, and then enter the second water tank 4. Furthermore, the control valve can be set between the active cooling system and the second water tank 4. When the water in the second water tank 4 is sufficient, the control valve can be closed to disconnect the connection between the active cooling system and the second water tank 4, which can ensure the cooling effect of the active cooling system on the water in the second water tank 4.

[0049] In some embodiments, the cooling fan assembly 100 further includes a control module, the second water tank 4 is provided with a liquid level detection element, and both the control valve and the liquid level detection element are electrically connected to the control module. The control module is used to control the control valve to open when the water level detected by the liquid level detection element is lower than a set height.

[0050] Specifically, the water level in the second water tank 4 has a set height. When the water level is higher than the set height, the water volume in the second water tank 4 is sufficient, and no water supply is required. When the water level is lower than the set height, the water volume in the second water tank 4 is low, and water supply is required. A liquid level detection device is installed in the second water tank 4 to detect the water level. Both the control valve and the liquid level detection device are electrically connected to the control module, so that the detection result of the liquid level detection device can be sent to the control module. The control module can then control the control valve according to the detection result of the liquid level detection device, so that when the water level detected by the liquid level detection device is lower than the set height, the control valve is opened, allowing the main water tank 3 to supply water to the second water tank 4.

[0051] Furthermore, when the level detection device detects that the water level in the second water tank 4 is lower than the set height, the control module can control the control valve to open, so as to connect the main water tank 3 and the second water tank 4, allowing the main water tank 3 to supply water to the second water tank 4. When the level detection device detects that the water level in the second water tank 4 is higher than the set height, the control module can control the control valve to close, so as to disconnect the main water tank 3 from the second water tank 4, preventing the main water tank 3 from supplying too much water to the second water tank 4, causing the water in the second water tank 4 to overflow.

[0052] In some embodiments, the main water tank 3 is located below the cooling fan wheel 1.

[0053] Specifically, the main water tank 3 is used to supply water to the second water tank 4, and the second water tank 4 is located below the main water tank 3. By placing the main water tank 3 below the cooling fan impeller 1, both the main water tank 3 and the second water tank 4 can be placed below the cooling fan impeller 1. This means that both the main water tank 3 and the second water tank 4 can be placed at the lower part of the cooling fan assembly 100, which can improve the overall stability of the cooling fan assembly 100, prevent it from tipping over, and make the distance between the main water tank 3 and the second water tank 4 closer, so that the main water tank 3 can supply water to the second water tank 4, which helps to reduce water supply costs. In addition, it can also prevent the main water tank 3 from obstructing the cooling fan impeller 1, that is, to avoid obstructing the airflow driven by the cooling fan impeller 1, which would result in poor cooling effect of the cooling fan assembly 100.

[0054] In other embodiments, such as Figure 1As shown, when using the cold source 41 to cool the water in the second water tank 4, a first connection port 32 can be provided in the main water tank 3. The first connection port 32 can connect the inside of the main water tank 3 to the outside, so that the water in the main water tank 3 can flow out from the first connection port 32. A second connection port 43 can be provided in the second water tank 4. The second connection port 43 can connect the inside of the second water tank 4 to the outside, so that the water outside can flow into the second water tank 4 from the second connection port 43. The first connection port 32 and the second connection port 43 are connected through the connecting pipe 31, so that the water in the main water tank 3 can flow from the first connection port 32 to the connecting pipe 31, and then enter the second water tank 4 from the connecting pipe 31 through the second connection port 43, thereby realizing the supply of water from the main water tank 3 to the second water tank 4.

[0055] It should be noted that the first connection port 32 can be located on the side wall or below the main water tank 3, and the second connection port 43 can be located on the side wall or above the second water tank 4. The first connection port 32 and the second connection port 43 can be connected through the connecting pipe 31 to realize the connection between the main water tank 3 and the second water tank 4. Furthermore, by setting the second water tank 4 below the main water tank 3, the second water tank 4 can be moved closer to the main water tank 3, thereby reducing the length of the connecting pipe 31 and helping to reduce the installation cost. Moreover, the setting positions of the first connection port 32 and the second connection port 43 can be flexibly set according to specific circumstances.

[0056] Furthermore, when using the active cooling system to cool the water in the second water tank 4, a first connection port 32 can be provided in the main water tank 3. The first connection port 32 can be connected to the active cooling system through a cooling pipe, so that the water in the main water tank 3 can enter the active cooling system from the first connection port 32 along the cooling pipe, and then enter the second water tank 4 from the active cooling system, thereby realizing the supply of water to the second water tank 4 and the cooling of the water in the second water tank 4.

[0057] In some embodiments, the main water tank 3 is detachably connected to the second water tank 4; and / or, the second water tank 4 is provided with a vent 44, which communicates with the atmosphere.

[0058] Specifically, the main water tank 3 is used to supply water to the second water tank 4. The main water tank 3 and the second water tank 4 are detachably connected, which makes it easy to connect or separate the main water tank 3 and the second water tank 4. Thus, when the water volume in the second water tank 4 is low and water needs to be supplied to the second water tank 4, the main water tank 3 can be connected to the second water tank 4 so that the main water tank 3 can supply water to the second water tank 4. Or, when water needs to be added to the main water tank 3, the main water tank 3 can be separated from the second water tank 4 so that water can be added to the main water tank 3, ensuring the reliability of the main water tank 3.

[0059] Meanwhile, the second water tank 4 is equipped with a vent 44, which allows the second water tank 4 to remain open to the atmosphere. This allows the interior of the second water tank 4 to be connected to the outside, so as to balance the pressure inside the second water tank 4 and prevent the second water tank 4 from deforming or cracking due to excessively high or low pressure. Moreover, by balancing the pressure, it can be ensured that the second water tank 4 operates within a safe pressure range, thus extending its service life.

[0060] In some embodiments, a top-opening member 51 is provided between the second water tank 4 and the main water tank 3. The bottom of the main water tank 3 is provided with a water outlet 33 and a sealing member 34 is provided at the water outlet 33. When the main water tank 3 is installed on the second water tank 4, the top-opening member 51 opens the sealing member 34 and makes the water outlet 33 face the second water tank 4 to supply water.

[0061] Specifically, such as Figure 2 As shown, a water outlet 33 is provided at the bottom of the main water tank 3. The water outlet 33 can connect the inside of the main water tank 3 with the outside, so that the water in the main water tank 3 can flow out from the water outlet 33. A sealing element 34 is provided at the water outlet 33. The sealing element 34 is used to open or close the water outlet 33. The sealing element 34 can be constructed to be movable relative to the main water tank 3, so that the water outlet 33 can be opened or closed at the same time. At the same time, a top opening element 51 is provided between the second water tank 4 and the main water tank 3. The top opening element 51 is used to open the sealing element 34 when the main water tank 3 is installed in the second water tank 4. The top opening element 51 can be constructed to extend in the vertical direction, so that when the main water tank 3 is installed in the second water tank 4, the top opening element 51 can press against the sealing element 34 and push the sealing element 34 to move relative to the main water tank 3 to open the water outlet 33, thereby realizing the connection between the main water tank 3 and the second water tank 4, so that the main water tank 3 can supply water to the second water tank 4.

[0062] Furthermore, when the cold source 41 is used to cool the water in the second water tank 4, a connecting water tank 5 can be provided in the second water tank 4, that is, the connecting water tank 5 is connected to the second water tank 4, and the water in the connecting water tank 5 can enter the second water tank 4. The connecting water tank 5 is located below the main water tank 3. The top opening member 51 can be provided in the connecting water tank 5, so that when the main water tank 3 is installed in the second water tank 4, the top opening member 51 can push the sealing member 34 to move relative to the main water tank 3 to open the water outlet 33, thereby realizing the connection between the main water tank 3 and the connecting water tank 5, so that the water in the main water tank 3 can enter the connecting water tank 5 from the water outlet 33, and then enter the second water tank 4.

[0063] It should be noted that, for example Figure 2As shown, the main water tank 3 is located above the connecting water tank 5, and the outlet 33 is located at the bottom of the main water tank 3, so that the main water tank 3 is connected to the connecting water tank 5 through the outlet 33. This allows the main water tank 3 to control the water level in the connecting water tank 5. The connecting water tank 5 is connected to the second water tank 4, and the second water tank 4 is open to the atmosphere through the vent 44. This allows the water level in the second water tank 4 to be controlled by the water level in the connecting water tank 5 using the principle of communicating vessels, thus enabling the main water tank 3 to replenish the second water tank 4 in a timely manner.

[0064] Furthermore, when using the active cooling system to cool the water in the second water tank 4, an outlet 33 can be provided at the bottom of the main water tank 3, and a top opening 51 can be provided in the cooling pipeline so that the top opening 51 can be used to control the connection and disconnection between the main water tank 3 and the active cooling system, thereby controlling the water supply from the main water tank 3 to the second water tank 4. The first connection port 32 and the outlet 33 can be constructed as the same, so that the connection and disconnection between the main water tank 3 and the active cooling system can be controlled by the top opening 52.

[0065] In some embodiments, the air cooler assembly 100 further includes an elastic member 35, a limiting portion 36 is provided in the water outlet 33, the elastic member 35 elastically presses against the limiting portion 36 and the sealing member 34 respectively, and is used to push the sealing member 34 to close the water outlet 33.

[0066] Specifically, a limiting part 36 is provided at the water outlet 33. The sealing member 34 can cooperate with the limiting part 36 to open or close the water outlet 33. When the sealing member 34 is in contact with the limiting part 36, the water outlet 33 can be closed. When the sealing member 34 is separated from the limiting part 36, the water outlet 33 can be opened. The two ends of the elastic member 35 are elastically pressed against the limiting part 36 and the sealing member 34 respectively. The elastic member 35 can be placed between the limiting part 36 and the sealing member 34, so that the elastic member 35 can push the sealing member 34 to move to close the water outlet 33.

[0067] Among them, such as Figure 2 As shown, the sealing member 34 is constructed in an I-shape. One end of the sealing member 34 extends into the interior of the limiting part 36, and the other end is located outside the limiting part 36. The two ends of the elastic member 35 are respectively pressed against the limiting part 36 and the end of the sealing member 34 located outside the limiting part 36. When the main water tank 3 is installed on the second water tank 4, the opening member 51 can press against the end of the sealing member 34 located outside the limiting part 36 to make the sealing member 34 move into the main water tank 3 to open the outlet 33. At this time, the elastic member 35 is compressed by force. When the main water tank 3 is removed from the second water tank 4, the opening member 51 separates from the sealing member 34. At this time, the elastic member 35 can push the sealing member 34 to move out of the main water tank 3 under the action of restoring force to close the outlet 33, which can prevent the water in the main water tank 3 from flowing out accidentally.

[0068] In some embodiments, the cooling fan assembly 100 further includes a first temporary receiving cavity 6, which is located above the wet curtain 2 and communicates with the upper end of the first connecting pipe 42, and the bottom of the first temporary receiving cavity 6 is provided with a drain hole; and / or, it further includes a second temporary receiving cavity 7, which is located below the wet curtain 2 and communicates with the second water tank 4 through the second connecting pipe 71.

[0069] Specifically, the first temporary containment cavity 6 can be used to contain low-temperature water. The first temporary containment cavity 6 is located above the wet curtain 2 and is connected to the upper end of the first connecting pipe 42, so that the water in the second water tank 4 can flow along the first connecting pipe 42 into the first temporary containment cavity 6. A water leakage hole is provided at the bottom of the first temporary containment cavity 6, which is used to allow the low-temperature water in the first temporary containment cavity 6 to drip onto the wet curtain 2 for heat exchange with the airflow, so that the cooling fan assembly 100 can blow out cold air.

[0070] Meanwhile, the second temporary containment chamber 7 can be used to contain low-temperature water. The second temporary containment chamber 7 is located below the wet curtain 2 so that excess water on the wet curtain 2 can drip into the second temporary containment chamber 7 to collect the excess water on the wet curtain 2, which can avoid water dripping on the ground and causing inconvenience to users. The second temporary containment chamber 7 is connected to the second water tank 4 through the second connecting pipe 71. The two ends of the second connecting pipe 71 are connected to the second temporary containment chamber 7 and the second water tank 4 respectively, so that the water in the second temporary containment chamber 7 can flow to the second water tank 4 along the second connecting pipe 71.

[0071] Therefore, during the use of the air cooler assembly 100, the low-temperature water in the second water tank 4 can first flow along the first connecting pipe 42 to the first temporary receiving cavity 6, and drip from the drain hole at the bottom of the first temporary receiving cavity 6 onto the wet curtain 2 to exchange heat with the airflow. The excess low-temperature water on the wet curtain 2 can drip into the second temporary receiving cavity 7, and enter the second water tank 4 from the second temporary receiving cavity 7 along the second connecting pipe 71, which can realize the circulation of low-temperature water. Moreover, the low-temperature water in the second temporary receiving cavity 7 can re-enter the circulation after entering the second water tank 4, thereby reducing resource waste.

[0072] In some embodiments, the second water tank 4 is provided with a first insulation layer; and / or, the first connecting pipe 42 is provided with a second insulation layer.

[0073] Specifically, the second water tank 4 can be made of heat-insulating material to reduce heat exchange between the low-temperature water after absorbing cold energy and the external environment. A first heat-insulating layer is provided outside the second water tank 4. The first heat-insulating layer can be made of heat-insulating material and can be wrapped around the second water tank 4 to isolate external heat, reduce heat exchange between the low-temperature water in the second water tank 4 and the external environment, and improve the cooling effect of the air cooler assembly 100. At the same time, a second heat-insulating layer can be provided outside the first connecting pipe 42. The second heat-insulating layer can be made of heat-insulating material and can be wrapped around the first connecting pipe 42 to isolate external heat, reduce heat exchange between the low-temperature water in the second water tank 4 and the external environment during the flow of the low-temperature water in the second water tank 4 along the first connecting pipe 42 to the first temporary receiving cavity 6, and further improve the cooling effect of the air cooler assembly 100.

[0074] It should be noted that both the first and second insulation layers can be used to insulate against external heat. In actual design, the first and second insulation layers can also be constructed as an air layer to reduce installation costs.

[0075] And, it should be noted that, such as Figure 1 As shown, when using the cold source 41 to cool the water in the second water tank 4, a selectively openable cold source inlet 45 can be provided on the second water tank 4 to add the cold source 41 into the second water tank 4. The cold source inlet 45 can be opened when it is necessary to add the cold source 41 to the second water tank 4 to add the cold source 41 to cool the water. The cold source inlet 45 can be closed after the cold source 41 has been added or when it is not necessary to add the cold source 41, so as to seal the second water tank 4 and reduce the heat exchange between the low temperature water and the external environment.

[0076] Furthermore, when using an active cooling system to cool the water in the second water tank 4, the number of cold source inlets 45 can be reduced, thus improving the sealing performance of the second water tank 4.

[0077] And, such as Figure 3 The flowchart shown is for this application. At the beginning, the cooling fan assembly 100 is started, and the cooling components begin to cool. At the same time, the liquid level detection device monitors the water level in the second water tank 4 in real time. When the water level is detected to be lower than the set height, the control valve can be opened to supply water from the main water tank 3 to the second water tank 4. After the water supply is completed, the water pump can be turned on to start water circulation, thereby realizing the cooling function of the cooling fan assembly 100. After the cooling fan assembly 100 has been working for a period of time, when the water in the second water tank 4 is consumed to the point that the water level is lower than the set height, water can be selectively supplied to the second water tank 4. After water supply, water circulation can continue. If the water in the second water tank 4 is not replenished within a specified time, the cooling fan assembly 100 is turned off, and the entire process ends.

[0078] If an active cooling system is used to cool the water in the second water tank 4, the water temperature in the second water tank 4 also needs to be detected. When the water temperature is lower than the preset temperature, water circulation is activated.

[0079] Furthermore, this application places the second water tank 4 below the main water tank 3, allowing gravity to be used to fill the second water tank 4, resulting in lower overall costs. In actual design, the second water tank 4 can also be placed above the main water tank 3 or even on the top of the entire unit, which would bring the second water tank 4 closer to the wet curtain 2 and reduce cooling loss. In both of these arrangements, the main water tank 3 does not directly participate in the water circulation, so the water in the main water tank 3 will always be clean, making it convenient for users to clean the main water tank 3.
