Description

Technical Field

[0001] The utility model relates to the technical field of wet curtain liquid distributing, in particular to a wet curtain liquid distributing device and a cooling fan formed by the wet curtain liquid distributing device. Background Art

[0002] The wet curtain liquid distributor in the cooling fan pumps water through the water pump and the water outlet into the wet curtain. Since the water outlets are densely distributed, it is impossible to evenly discharge water to the wet curtain from each water outlet. When observing the whole machine working, it will be found that the wet curtain is not evenly moistened, and some areas are dry and not wet, which will affect the humidification effect of the wet curtain.

[0003] The Chinese patent application with publication number CN113669885A discloses a liquid distributor, including a liquid distribution tank and a plurality of liquid distribution holes arranged on the liquid distribution tank; the wet curtain bracket is integrally formed with the liquid distribution tank; the wet curtain body is preferably a paper porous material with high water absorption and high water resistance, and is correspondingly arranged at the lower side of the liquid distribution hole, suitable for receiving the water from the liquid distribution hole. Although this scheme can make the liquid in the liquid distribution tank enter the wet curtain evenly, the liquid distribution hole is located above the wet curtain, and the two are not in direct contact. In the process of the liquid in the liquid distribution hole flowing to the wet curtain, part of the water flow splashes out of the wet curtain under the action of wind, that is to say, the water flow of the liquid distributor is lost when it flows through the drain hole, and not all of it flows into the wet curtain; this will increase the loss of water in the liquid distributor and affect the humidification effect of the wet curtain. Utility Model Content

[0004] In order to overcome the problems existing in the related technology, one of the purposes of the utility model is to provide a wet curtain liquid distributor, by assembling the water downhole in the liquid distribution groove of the wet curtain, so that the liquid in the liquid carrying cavity can evenly enter the wet curtain through the water downhole, thereby avoiding liquid splashing and improving liquid utilization.

[0005] A wet curtain liquid distributor comprises a wet curtain and a liquid distributor, wherein a liquid distribution groove is arranged on the top of the wet curtain; the liquid distributor comprises a liquid carrying cavity and a plurality of water discharge holes evenly distributed below the liquid carrying cavity, and the water discharge holes are located inside the liquid distribution groove.

[0006] The liquid inside the liquid-carrying chamber of the present application can directly drip into the liquid distribution groove through the drain hole, that is, the liquid-carrying chamber is directly connected with the wet curtain through the drain hole, avoiding the phenomenon of liquid splashing caused by the long distance between the wet curtain and the liquid distributor in the prior art; at the same time, the evenly distributed drain holes of the present application can evenly disperse the liquid in the liquid-carrying chamber at various positions of the wet curtain, and the liquid is immersed in the wet curtain through the liquid distribution groove, thereby realizing uniform dispersion of the liquid in the wet curtain.

[0007] In a preferred technical solution of the utility model, it also includes a lifting drive component, which is connected to the wet curtain and can drive the wet curtain to move towards or away from the liquid distributor.

[0008] The function of the lifting drive is to drive the wet curtain to move towards or away from the liquid distributor. When the wet curtain is away from the liquid distributor, the liquid distribution groove is separated from the water discharge hole. At this time, there is no liquid in the liquid-carrying cavity, that is, the wet curtain is not in working state. At this time, the wet curtain can be replaced or maintained. When the wet curtain is close to the liquid distributor, the water discharge hole is located in the liquid distribution groove. The evenly distributed water discharge holes can evenly distribute the liquid in the liquid-carrying cavity at various positions of the wet curtain. The liquid penetrates into the wet curtain through the liquid distribution groove, realizing even dispersion of the liquid in the wet curtain.

At this time, the elastic force of the spring on the wet curtain is equal to the gravity of the wet curtain, and the wet curtain is in a stable state; the evenly distributed drain holes can evenly disperse the liquid in the liquid-carrying cavity at various positions of the liquid distribution groove. When the wet curtain needs to be replaced or maintained, the liquid in the liquid-carrying cavity is drained, the water supply to the wet curtain is stopped, and the wet curtain is compressed downward. At this time, the spring is compressed, the drain hole is separated from the liquid distribution groove, and the wet curtain can be easily taken out for replacement. The spring is used as a lifting drive component with a simple structure and a small footprint, which reduces the overall structure of the wet curtain. The wet curtain and the liquid distributor can be easily separated and assembled through the water hole and the liquid distribution groove structure, thereby improving the water supply efficiency of the wet curtain.

[0041] Example 1

[0042] like Figure 1-Figure 8 As shown, the present application provides a wet curtain liquid distributor, comprising a wet curtain 22 and a liquid distributor 1, wherein a liquid distribution groove 23 is provided on the top of the wet curtain 22; the liquid distributor 1 comprises a liquid carrying cavity 11 and a plurality of water discharge holes 12 evenly distributed below the liquid carrying cavity 11, and the water discharge holes 12 are located inside the liquid distribution groove 23.

[0043] In the present application, the liquid distribution groove 23 can be located at any position of the wet curtain 22. Preferably, the liquid distribution groove 23 is located at the top of the wet curtain 22. After the liquid in the liquid-carrying chamber 11 enters the liquid distribution groove 23 through the water hole 12, the liquid extends toward the bottom of the wet curtain 22 under the action of gravity, so that the entire wet curtain 22 is soaked by the liquid. In this way, the utilization efficiency of the wet curtain 22 can be improved.

[0044] In the present application, the liquid distribution groove 23 is an annular structure surrounding the top of the wet curtain 22, which is an integrated structure. The water holes 12 are evenly distributed below the liquid-carrying chamber 11, that is, the water holes 12 are evenly distributed in the annular liquid distribution groove 23. The liquid in the liquid-carrying chamber 11 drips evenly into the liquid distribution groove 23 through the water holes 12. Under the action of gravity, the liquid extends from the top of the wet curtain 22 to the bottom of the wet curtain 22, ensuring that all positions of the wet curtain 22 are evenly wetted.

[0045] The liquid inside the liquid-carrying chamber 11 of the present application can directly drip into the liquid distribution groove 23 through the water discharge hole 12, that is, the liquid-carrying chamber 11 is directly connected with the wet curtain 22 through the water discharge hole 12, thereby avoiding the phenomenon of liquid splashing caused by the long distance between the wet curtain 22 and the liquid distributor 1 in the prior art; at the same time, the evenly distributed water discharge holes 12 of the present application can evenly disperse the liquid in the liquid-carrying chamber 11 at various positions of the wet curtain 22, and the liquid is immersed in the wet curtain 22 through the liquid distribution groove 23, thereby realizing the uniform dispersion of the liquid in the wet curtain 22.

[0046] Example 2

[0047] like Figure 1-Figure 8 As shown, the present application provides a wet curtain liquid distributor, comprising a wet curtain 22 and a liquid distributor 1, wherein a liquid distribution groove 23 is provided on the top of the wet curtain 22; the liquid distributor 1 comprises a liquid carrying cavity 11 and a plurality of water discharge holes 12 evenly distributed below the liquid carrying cavity 11, and the water discharge holes 12 are located inside the liquid distribution groove 23.

[0048] Furthermore, the present application also includes a lifting drive component, which is connected to the wet curtain 22 and can drive the wet curtain 22 to move in a direction close to or away from the liquid distributor 1.

[0049] The function of the lifting drive member is to drive the wet curtain 22 to move toward or away from the liquid distributor 1. When the wet curtain 22 is away from the liquid distributor 1, the liquid distribution groove 23 is separated from the water discharge hole 12. At this time, there is no liquid in the liquid-carrying chamber 11, that is, the wet curtain 22 is not in working state. At this time, the wet curtain 22 can be replaced or maintained. When the wet curtain 22 is close to the liquid distributor 1, the water discharge hole 12 is located in the liquid distribution groove 23. The evenly distributed water discharge holes 12 can evenly distribute the liquid in the liquid-carrying chamber 11 at various positions of the wet curtain 22. The liquid penetrates into the wet curtain 22 through the liquid distribution groove 23, so that the liquid in the wet curtain 22 is evenly dispersed.

[0050] As a specific implementation, the lifting drive member in the present application can be a cylinder, the output end of the cylinder is connected to the bottom of the wet curtain 22, the extension and retraction of the cylinder drives the wet curtain 22 to rise and fall, and the extension and retraction stroke of the cylinder is controlled so that the extension and retraction stroke corresponds to the height of the water hole 12. When the cylinder is extended, the water hole 12 is located inside the liquid distribution groove 23, and when the cylinder is retracted, the water hole 12 is separated from the liquid distribution groove 23.

[0051] As a specific implementation, the lifting drive component in the present application can also be a motor and a screw. The output end of the motor is connected to the wet curtain 22 through the screw. The rotation of the screw driven by the motor can be converted into the vertical movement of the wet curtain 22, thereby realizing the lifting and lowering of the wet curtain 22.

[0052] As a specific implementation, the lifting drive member in the present application is a spring 33 , and the wet curtain 22 is fixed to the top of the support platform 31 by the spring 33 .

[0053] In the present application, the liquid distribution groove 23 is located at the top of the wet curtain 22. After the liquid in the liquid-carrying chamber 11 enters the liquid distribution groove 23 through the water hole 12, the liquid extends toward the bottom of the wet curtain 22 under the action of gravity, so that the entire wet curtain 22 is soaked by the liquid. The bottom of the wet curtain 22 is fixed to the top of the support platform 31 by a spring 33. The support platform 31 refers to a platform for installing the wet curtain 22. When the water hole 12 is located in the liquid distribution groove 23, the spring 33 has an upward supporting force on the wet curtain 22. At this time, the elastic force of the spring 33 on the wet curtain 22 is equal to the gravity of the wet curtain 22, and the wet curtain 22 is in a stable state; the evenly distributed water holes 12 can evenly disperse the liquid in the liquid-carrying chamber 11 at various positions of the liquid distribution groove 23. When the wet curtain 22 needs to be replaced or maintained, the liquid in the liquid-carrying chamber 11 is drained, the water supply to the wet curtain 22 is stopped, and the wet curtain 22 is compressed downward. At this time, the spring 33 is compressed, the water hole 12 is separated from the liquid distribution groove 23, and the wet curtain 22 can be easily taken out for replacement. The spring 33 is used as a lifting drive component, with a simple structure and a small footprint, which reduces the overall structure of the wet curtain 22. The wet curtain 22 can be easily separated and assembled from the liquid distributor 1 through the water hole 12 and the liquid distribution groove 23 structure, thereby improving the water supply efficiency of the wet curtain 22.

[0054] In the present application, the depth of the liquid distribution groove 23 is greater than or equal to the height of the water hole 12, and the height of the water hole 12 refers to the farthest distance between the water hole 12 and the liquid-carrying cavity 11. When the water hole 12 is located inside the liquid distribution groove 23, the evenly distributed water holes 12 can evenly disperse the liquid in the liquid-carrying cavity 11 at various positions of the liquid distribution groove 23; at this time, the bottom of the water hole 12 does not need to contact the bottom of the liquid distribution groove 23. Due to the existence of the side of the liquid distribution groove 23, even if the bottom of the water hole 12 is a distance away from the bottom of the liquid distribution groove 23, the liquid will not splash under the limiting effect of the side of the liquid distribution groove 23. Therefore, the present application sets the depth of the liquid distribution groove 23 to be greater than or equal to the height of the water hole 12. When the water hole 12 is located inside the liquid distribution groove 23, the liquid carrying cavity 11 can be flush with and abut against the top of the liquid distribution groove 23, and the water hole 12 penetrates deep into the liquid distribution groove 23. The side walls of the liquid distribution groove 23 and the liquid carrying cavity 11 both protect the liquid in the water hole 12, thereby preventing the liquid from splashing out from the top and sides of the liquid distribution groove 23, thereby improving the wetting efficiency of the wet curtain 22.

In the present application, the bracket bottom plate 24 is a circular structure, and the assembly ribs 25 are evenly distributed at the edge of the bracket bottom plate 24 and are arranged perpendicular to the bracket bottom plate 24. The annular wet curtain 22 is sleeved on the outer peripheral side of the assembly ribs 25. In the present application, the assembly ribs 25 can be arranged on the outer peripheral side of the circular bracket bottom plate 24 and at a certain distance from the edge. In this way, the edge of the bracket bottom plate 24 can also support the bottom of the wet curtain 22, ensuring that the inner wall of the wet curtain 22 is limited and fixed by the assembly ribs 25, and the bottom of the wet curtain 22 is supported by the bracket bottom plate 24, which is conducive to fixing the position of the wet curtain 22.

The function of the lifting drive member is to drive the wet curtain 22 to move in a direction close to or away from the liquid distributor 1. When the wet curtain 22 is away from the liquid distributor 1, the liquid distribution groove 23 is separated from the water discharge hole 12. At this time, there is no liquid in the liquid-carrying cavity 11, that is, the wet curtain 22 is not in a working state. At this time, the wet curtain 22 can be replaced or maintained. When the wet curtain 22 is close to the liquid distributor 1, the water discharge hole 12 is located in the liquid distribution groove 23. The evenly distributed water discharge holes 12 can evenly distribute the liquid in the liquid-carrying cavity 11 at various positions of the wet curtain 22.

When the wet curtain 22 needs to be replaced or maintained, the liquid in the liquid-carrying chamber 11 is drained, the water supply to the wet curtain 22 is stopped, and the wet curtain bracket is compressed downward. At this time, the spring 33 is compressed, the water hole 12 is separated from the liquid distribution groove 23, and the wet curtain 22 can be easily taken out for replacement. The spring 33 is used as a lifting drive component, with a simple structure and a small footprint, which reduces the overall structure of the wet curtain 22 and the wet curtain bracket, and the wet curtain 22 can be easily separated and assembled from the liquid distributor 1 through the water hole 12 and the liquid distribution groove 23 structure, thereby improving the water supply efficiency of the wet curtain 22.

[0068] In the present application, a handle 21 is provided at the top of the wet curtain bracket.

[0069] The handle 21 can be arranged at the top position of the assembly rib 25, such as Figure 5 As described above, the outer peripheral side of the assembly rib 25 is used to abut against and fix the wet curtain 22. Since the wet curtain 22 is an annular structure, the top of the assembly rib 25 is a hollow opening. In this application, the handle 21 is set at the top position of the assembly rib 25. When the wet curtain 22 needs to be replaced, the handle 21 can be held to press down the wet curtain bracket. The wet curtain bracket can drive the wet curtain 22 to compress the spring 33 downward, so that the liquid distribution groove 23 is separated from the water discharge hole 12, so as to achieve the replacement and maintenance of the wet curtain 22. When the water discharge hole 12 and the liquid distribution groove 23 need to be assembled together, it is only necessary to loosen the handle 21. Under the elastic force of the spring 33, the wet curtain 22 and the wet curtain bracket are reset and rebounded, so that the water discharge hole 12 is located inside the liquid distribution groove 23.

[0071] like Figure 8 As shown, a cooling fan provided by the present application includes a wet curtain liquid distributor as described above; and also includes a water delivery component and a fan 34 connected to the liquid-carrying chamber 11. Among them, the fan 34 is located above the wet curtain 22, and the water delivery component (not shown in the figure) is used to add liquid to the liquid-carrying chamber 11. The evenly distributed water holes 12 of the present application can evenly distribute the liquid in the liquid-carrying chamber 11 at various positions of the wet curtain 22, and the liquid is immersed in the wet curtain 22 through the liquid distribution groove 23, so as to achieve uniform dispersion of the liquid in the wet curtain 22; at the same time, the liquid-carrying chamber 11 is directly connected to the wet curtain 22 through the water holes 12, which avoids the phenomenon of liquid splashing caused by the long distance between the wet curtain 22 and the liquid distributor 1 in the prior art.

[0072] like Figure 1-Figure 7 As shown, the wet curtain 22 is an annular structure and is sleeved on the outside of the wet curtain bracket; the wet curtain bracket includes a bracket bottom plate 24 and assembly ribs 25 evenly distributed on the edge of the bracket bottom plate 24, the bracket bottom plate 24 is connected to the lifting drive member, and the wet curtain 22 is ringed on the outside of the assembly ribs 25.

[0073] In the present application, the wet curtain 22 is an annular structure, and the liquid distribution groove 23 is located at the top of the wet curtain 22, which is also an annular structure; the liquid carrying chamber 11 is also an annular structure, fixed to the top of the wet curtain 22, and the drain hole 12 below the liquid carrying chamber 11 is located inside the liquid distribution groove 23, so that the inner side walls of the liquid carrying chamber 11 and the liquid distribution groove 23 shield the liquid dripping from the drain hole 12 to avoid loss caused by liquid splashing.

[0074] In the present application, the bracket bottom plate 24 is a circular structure, and the assembly ribs 25 are evenly distributed at the edge of the bracket bottom plate 24 and are arranged perpendicular to the bracket bottom plate 24; the annular wet curtain 22 is sleeved on the outer peripheral side of the assembly ribs 25; and the top of the assembly ribs 25 is provided with a handle 21. In the present application, the assembly ribs 25 can be arranged at the outer peripheral side of the circular bracket bottom plate 24 and at a certain distance from the edge, so that the edge of the bracket bottom plate 24 can also support the bottom of the wet curtain 22, ensuring that the inner side wall of the wet curtain 22 is limited and fixed by the assembly ribs 25, and the bottom of the wet curtain 22 is supported by the bracket bottom plate 24.

[0075] like Figure 3 and Figure 4 As shown, a buckle 13 is also provided in the liquid distributor 1. Specifically, the liquid-carrying cavity 11 is an annular structure, and the buckle 13 is provided on the inner wall of the liquid-carrying cavity 11 near the center of the circle, and the liquid distributor 1 is fixed in the panel of the cooling fan by the buckle 13; the position of the liquid distributor 1 is ensured to be fixed, and the distribution and assembly between the liquid distribution groove 23 and the liquid distributor 1 are realized by lifting and lowering the wet curtain 22.

[0076] In the present application, the liquid distribution groove 23 is located at the top of the wet curtain 22. After the liquid in the liquid-carrying chamber 11 enters the liquid distribution groove 23 through the drain hole 12, the liquid extends toward the bottom of the wet curtain 22 under the action of gravity, so that the entire wet curtain 22 is soaked by the liquid. The bottom of the bracket bottom plate 24 is fixed to the top of the support platform 31 by a spring 33. When the drain hole 12 is located in the liquid distribution groove 23, the spring 33 has an upward supporting force on the bracket bottom plate 24. At this time, the elastic force of the spring 33 on the bracket bottom plate 24 is equal to the gravity of the wet curtain 22 and the wet curtain bracket, and the wet curtain 22 is in a stable state; the evenly distributed drain holes 12 can evenly disperse the liquid in the liquid-carrying chamber 11 at various positions of the liquid distribution groove 23. When the wet curtain 22 needs to be replaced or maintained, the liquid in the liquid-carrying chamber 11 is drained, the water supply to the wet curtain 22 is stopped, and the handle 21 is held to compress the wet curtain bracket downward. At this time, the spring 33 is compressed, and the water hole 12 is separated from the liquid distribution groove 23, so that the wet curtain 22 can be easily taken out for replacement. When the water hole 12 and the liquid distribution groove 23 need to be assembled together, it is only necessary to loosen the handle 21. Under the elastic force of the spring 33, the wet curtain 22 and the wet curtain bracket are reset and rebounded, so that the water hole 12 is located inside the liquid distribution groove 23.
