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

[0030] In addition, it needs to be explained that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

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

[0032] Therefore, the present application provides a wet curtain assembly as shown in Figures 1 to 5 The wet curtain assembly includes a wet curtain body 1, a semiconductor refrigeration sheet 2 arranged on the wet curtain body 1, and a cold guide sheet 3 arranged on the wet curtain body 1 and connected with the cold end of the semiconductor refrigeration sheet 2. The cold end of the semiconductor refrigeration sheet 2 is used for refrigeration, which directly cools the gas passing through the wet curtain assembly, effectively ensures the refrigeration effect, avoids the problem that the ice box needs to be used and the user needs to operate in the prior art, and improves the refrigeration effect of the wet curtain assembly and the cold fan.

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

[0034] When the wet curtain assembly is working, water needs to be supplied to the wet curtain body 1 from above the wet curtain body 1. Therefore, the wet curtain assembly further comprises a water supply tank 4 arranged above the wet curtain body 1, and the water supply tank 4 is provided with a first water supply hole 41 and a second water supply hole 42. The water supply tank 4 communicates with the wet curtain body 1 through the first water supply hole 41, and the water supply tank 4 communicates with the heat dissipation structure 7 through the second water supply hole 42. Water is supplied to the wet curtain body 1 from above through the first water supply hole 41 of the water supply tank 4. The water can flow on the wet curtain body 1 by gravity. When air passes through the wet curtain body 1, it is humidified and cooled by the water, thereby achieving the effect of refrigeration. The second water supply hole 42 supplies water to the heat dissipation structure 7. The heat of the heat dissipation structure 7 is taken away by the water, thereby ensuring the heat dissipation efficiency of the heat dissipation structure 7. At the same time, the heat dissipation structure 7 is prevented from dissipating heat to the air around the wet curtain assembly, thereby affecting the refrigeration effect of the wet curtain assembly and ensuring the refrigeration reliability of the wet curtain assembly.

[0035] The wet curtain assembly further comprises a water tank 5 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, thereby enabling the water to be supplied to the water supply tank 4 again for use. Since the volume of the water tank 5 is large, the heat in the heat dissipation structure 7 is diluted by the large amount of water in the water tank 5, so that the temperature of the water supplied to the water supply tank 4 again does not change, thereby ensuring the refrigeration effect of the wet curtain assembly.

[0036] Preferably, the number of the cold conducting sheets 3 is multiple, and all the cold conducting sheets 3 are arranged in parallel along the height direction of the wet curtain body 1. By arranging multiple cold conducting sheets 3, multiple points for cooling can be provided in the height direction of the wet curtain body 1, thereby ensuring the refrigeration effect of the wet curtain assembly.

[0037] Since the number of the cold conducting sheets 3 is multiple and arranged in the height direction, and the area size of the semiconductor refrigeration sheet 2 is small, it is impossible for the semiconductor refrigeration sheet 2 to contact all the cold conducting sheets 3 at the same time for cooling. Therefore, the wet curtain assembly further comprises a cold conducting strip 6 arranged on the wet curtain body 1, and the cold end of the semiconductor refrigeration sheet 2 is connected to all the cold conducting sheets 3 through the cold conducting strip 6. The cold conducting strip 6 is used to transfer the cold of the semiconductor refrigeration sheet 2 to all the cold conducting sheets 3, thereby ensuring the refrigeration efficiency of all the cold conducting sheets 3 and further ensuring the refrigeration effect of the wet curtain assembly.

[0038] The number of the semiconductor refrigerating sheets 2 is multiple, and the cold end of each semiconductor refrigerating sheet 2 is arranged at the connecting position of the cold strip 6 and one cold sheet 3. By arranging multiple semiconductor refrigerating sheets 2, the refrigeration effect is further improved, and by arranging the semiconductor refrigerating sheets 2 at the connecting position of the cold sheet 3 and the cold strip 6, the refrigeration efficiency of each cold sheet 3 is ensured, and the cold strip 6 is used to average the cold quantity between the multiple semiconductor refrigerating sheets 2, thereby ensuring the uniform and reliable overall refrigeration effect of the wet curtain assembly.

[0039] As an embodiment, the wet curtain body 1 has two opposite side walls, and the semiconductor refrigerating sheets 2 are arranged on the two side walls, and the end of the cold sheet 3 is arranged on the corresponding side wall and connected with the corresponding semiconductor refrigerating sheet 2. That is, multiple semiconductor refrigerating sheets 2 are arranged on both sides of the wet curtain body 1, so as to ensure the refrigeration efficiency of the wet curtain assembly, and the two ends of the cold sheet 3 are directly or indirectly connected with the corresponding semiconductor refrigerating sheet 2, so as to ensure that the cold quantity is supplied to any position of the cold sheet 3, avoid the problem that the cold quantity is only supplied to the single end of the cold sheet 3 and the other end cannot be effectively refrigerated, ensure the refrigeration reliability of the cold sheet 3, and further ensure the refrigeration effect of the wet curtain assembly.

[0040] A cold fan comprising the wet curtain assembly.

[0041] The cold fan further comprises a fan blade, the fan blade is arranged on one side of the wet curtain assembly, and a shielding structure is arranged between the hot end of the semiconductor refrigerating sheet 2 and the fan blade. After the water of the wet curtain contacts the cold sheet 3, the temperature of the water is reduced, and when the fan blade works, the gas flows to the wet curtain body 1, and the temperature of the blown wind is synchronously reduced after passing through the wet curtain after cooling, so that a better technical effect can be achieved, and the shielding structure can avoid the air flow of the fan blade blowing to the hot end of the semiconductor refrigerating sheet 2 and blowing out the heat generated by the semiconductor refrigerating sheet 2, thereby ensuring the working reliability of the cold fan.

[0042] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
