In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the prior art, in order to further reduce the temperature of the wind, an ice box or the like is generally placed in the water tank of the cooling fan to cool the water that is about to soak the wet curtain to achieve the purpose of sending out cold air. However, this method requires the user to take the ice box out of the cooling fan and put it into the refrigerator for freezing, and then put the frozen ice box into the cooling fan again. The operation is complicated, and there is a problem that the user forgets to freeze the ice box and the refrigeration requirement cannot be met, which seriously affects the user experience.

[0032] To this end, the present application provides a Figures 1 to 5 The wet curtain assembly shown includes: a wet curtain body 1; a semiconductor refrigeration sheet 2, which is arranged on the wet curtain body 1; and a cooling sheet 3, which is inserted into the wet curtain body 1 and connected to the cold end of the semiconductor refrigeration sheet 2. The cold end of the semiconductor refrigeration sheet 2 is used for cooling, and the gas passing through the wet curtain assembly is directly cooled, which can effectively ensure the cooling effect, avoid the problem of the prior art that an ice box is needed and the user needs to operate, which affects the user experience. In addition, a cooling sheet 3 is provided to transfer the cold generated by the semiconductor refrigeration sheet 2 to the middle of the wet curtain assembly, thereby ensuring that different positions of the wet curtain assembly can cool water, improving the cooling uniformity of the wet curtain assembly, and thus improving the cooling effect of the wet curtain assembly and the cold fan.

[0033] Since the cold end of the semiconductor refrigeration sheet 2 generates cold energy and the hot end generates heat when it is working, in order to ensure the normal operation of the semiconductor refrigeration sheet 2, the wet curtain assembly also includes a heat dissipation structure 7, and the heat dissipation structure 7 is arranged at the hot end of the semiconductor refrigeration sheet 2. The heat generated by the semiconductor refrigeration sheet 2 is dissipated by the heat dissipation structure 7, so that the cold end of the semiconductor refrigeration sheet 2 can continuously generate cold energy, thereby ensuring the cooling effect of the wet curtain assembly.

[0034] When the wet curtain assembly is working, it is necessary to supply water to the wet curtain body 1 from above the wet curtain body 1. For this purpose, the wet curtain assembly further includes a water supply trough 4, which is arranged above the wet curtain body 1, and is provided with a first water supply hole 41 and a second water supply hole 42. The water supply trough 4 is connected to the wet curtain body 1 through the first water supply hole 41, and the water supply trough 4 is connected to the heat dissipation structure 7 through the second water supply hole 42. Water is dripped onto the wet curtain body 1 through the first water supply hole 41 on the water supply trough 4, and water can flow on the wet curtain body 1 by gravity. When the air passes through the wet curtain body 1, it will be humidified and cooled by this part of water, thereby achieving a cooling effect. The second water supply hole 42 supplies water to the heat dissipation structure 7, and uses this part of water to take away the heat on the heat dissipation structure 7, thereby ensuring the heat dissipation efficiency of the heat dissipation structure 7, and also preventing the heat dissipation structure 7 from dissipating heat into the air around the wet curtain assembly to affect the cooling effect of the wet curtain assembly, thereby ensuring the cooling reliability of the wet curtain assembly.

[0035] The wet curtain assembly also includes a water tank 5, which is arranged below the wet curtain body 1, and the water tank 5 can receive the drainage of the wet curtain body 1 and the drainage of the heat dissipation structure 7. The water tank 5 is used to recycle the water flowing out of the wet curtain body 1 and the water flowing out of the heat dissipation structure 7, so that it can be supplied to the water supply tank 4 for use again. Since the volume of the water tank 5 is large, the heat in the heat dissipation structure 7 will be diluted by a large amount of water in the water tank 5, so that the temperature of the water sent to the water supply tank 4 again will not change, thereby ensuring the cooling effect of the wet curtain assembly.

[0036] Preferably, there are multiple cooling fins 3, and all the cooling fins 3 are arranged in parallel along the height direction of the wet curtain body 1. By arranging multiple cooling fins 3, cooling can be provided at multiple points in the height direction of the wet curtain body 1, thereby ensuring the cooling effect of the wet curtain assembly.

[0037] Since there are multiple cooling fins 3 and they are arranged in the height direction, and the area size of the semiconductor refrigeration sheet 2 is small, it is impossible to contact all the cooling fins 3 at the same time to provide cooling. For this reason, the wet curtain assembly also includes a cooling strip 6, which is arranged on the wet curtain body 1, and the cold end of the semiconductor refrigeration sheet 2 is connected to all the cooling fins 3 through the cooling strip 6. The cooling strip 6 is used to transfer the cold of the semiconductor refrigeration sheet 2 to all the cooling fins 3, thereby ensuring the cooling efficiency of all the cooling fins 3 and further ensuring the cooling effect of the wet curtain assembly.

[0038] There are multiple semiconductor refrigeration sheets 2, and the cold end of each semiconductor refrigeration sheet 2 is arranged at the connection position between the cooling strip 6 and one of the cooling strips 3. The cooling effect is further improved by arranging multiple semiconductor refrigeration sheets 2, and arranging them at the connection position between the cooling strip 3 and the cooling strip 6, which can not only ensure the cooling efficiency of each cooling strip 3, but also use the cooling strip 6 to average the cooling between the multiple semiconductor refrigeration sheets 2, thereby ensuring that the overall cooling effect of the wet curtain assembly is uniform and reliable.

[0039] As an embodiment, the wet curtain body 1 has two opposite side walls, and the semiconductor refrigeration sheet 2 is arranged on both side walls, and the end of the cooling plate 3 is located on the corresponding side wall and connected to the corresponding semiconductor refrigeration sheet 2. That is, multiple semiconductor refrigeration sheets 2 are arranged on both sides of the wet curtain body 1 to ensure the cooling efficiency of the wet curtain assembly, and at the same time, both ends of the cooling plate 3 are directly or indirectly connected to the corresponding semiconductor refrigeration sheet 2, so as to ensure that any position of the cooling plate 3 obtains cooling, avoid the problem of supplying cooling only at a single end of the cooling plate 3 while the other end cannot be effectively cooled, ensure the cooling reliability of the cooling plate 3, and then ensure the cooling effect of the wet curtain assembly.

[0040] A cooling fan comprises the wet curtain assembly mentioned above.

[0041] The cooling fan also includes a fan blade, which is located on one side of the wet curtain assembly, and a shielding structure is arranged between the hot end of the semiconductor refrigeration sheet 2 and the fan blade. The temperature of water soaking the wet curtain will decrease after contacting the cooling sheet 3. When the fan blade is working, it can make the gas flow to the wet curtain body 1, and after passing through the wet curtain after cooling, the temperature of the blown wind is simultaneously reduced, thereby achieving a better technical effect. At the same time, the shielding structure can prevent the airflow of the fan blade from blowing to the hot end of the semiconductor refrigeration sheet 2 and blowing out the heat generated by the semiconductor refrigeration sheet 2, thereby ensuring the working reliability of the cooling fan.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
