Description

Technical Field

[0001] This utility model relates to the technical field of air inlet guiding devices, and in particular to an air inlet guiding device for a cooling tower. Background Technology

[0002] Cooling towers generally consist of a packing layer, a water collection tank, exhaust facilities, and an air inlet guide device. They are widely used in air conditioning, petrochemical, metallurgical, and power industries. Their function is to exchange heat between the medium carrying waste heat and the air inside the tower, dissipating the waste heat air into the atmosphere, thereby reducing the temperature of the medium itself. Common cooling tower air inlet guide devices have a fixed angle between the guide plates inside, which cannot be changed according to the airflow, resulting in reduced air intake cooling efficiency. At the same time, the air inlet guide device of the cooling tower cannot process the incoming air, which can easily cause impurities and dust carried in the air to enter the cooling tower.

[0003] Chinese patent document CN213147466U discloses a cooling tower air inlet guiding device, relating to the technical field of air inlet guiding devices. It includes a tower body with a horizontally fixed packing beam inside. Two sets of guide plate assemblies are symmetrically fixed in the area below the packing beam within the tower body. Each guide plate assembly includes two side baffles arranged horizontally and vertically, with a vertically arranged middle baffle fixed between the two side baffles. The height of the middle baffle is lower than that of the two side baffles. The side baffles are equidistant from the inner wall of the tower body and from the middle baffle. This invention solves the problem in traditional cooling towers where uneven airflow due to the tower structure easily creates dead air zones at the air inlet, leading to vortices and reduced heat exchange performance.

[0004] However, in actual use, the vertically arranged baffles of the device are subjected to uneven force, have poor resistance to deformation, and relatively poor stability. Utility Model Content

[0005] The main purpose of this utility model is to provide a cooling tower air inlet guide device that can effectively solve the problems of uneven force on the baffle, poor resistance to deformation, and relatively poor stability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cooling tower air inlet guiding device includes a guiding frame fixed to the air inlet of the cooling tower, and multiple guiding units are fixed inside the guiding frame. Both the guiding frame and the guiding units are made of stainless steel. A sealing gasket is provided at the air inlet of the cooling tower and the guiding frame.

[0008] Preferably, the airflow guiding unit includes multiple triangular hollow structures, which are arranged in a gradient from left to right to guide the airflow to diffuse in layers.

[0009] Preferably, the triangular hollow structure is an equilateral triangle.

[0010] Preferably, the apex of the triangular hollow structure is designed with a rounded arc.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model is made of stainless steel, which, with its corrosion resistance and high strength, can adapt to the humid environment of the cooling tower and extend the service life of the device. The flow guiding unit contains multiple equilateral triangular hollow structures arranged in a gradient from left to right. The large triangles can dominate the overall flow direction and divide and organize large-scale fluids, while the small triangles can handle local turbulence and eddies, gradually refining the flow field and reducing energy loss. Moreover, the symmetrical structure of the equilateral triangles can evenly distribute the load when subjected to force, improving the resistance to deformation. The rounded design of the apex can make the fluid flow around gradually, reduce local eddies, and increase the stability of the device.

[0013] 2. This utility model uses a rubber sealing gasket, which can not only increase the sealing of the connection, but also play a buffering role and reduce the shaking of the cooling tower frame during operation. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0015] In the diagram: 1. Flow guide frame; 2. Flow guide unit; 3. Sealing gasket. Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 As shown, a cooling tower air inlet guiding device includes a rectangular guiding frame 1 fixed to the air inlet of the cooling tower. Multiple guiding units 2 are fixed inside the guiding frame 1. In addition, in order to extend the service life of the device, both the guiding frame 1 and the guiding units 2 are made of stainless steel. Due to its corrosion resistance and high strength, it can be used in the humid environment of the cooling tower, thereby extending the service life of the device.

[0018] In addition, the flow guiding unit 2 includes multiple triangular hollow structures, which are arranged in a gradient from left to right to guide the airflow to diffuse in layers. The hollow triangular design allows the large triangles to dominate the overall flow direction, quickly dividing and organizing large-scale fluids, while the small triangles handle local turbulence and eddies (such as disturbances in the fluid boundary layer), thus refining the flow field step by step and reducing energy loss.

[0019] Furthermore, a sealing gasket 3 is provided at the air inlet of the cooling tower and the flow guide frame 1. The sealing gasket 3 is made of rubber, which can increase the sealing performance at the connection between the flow guide frame 1 and the air inlet of the cooling tower. At the same time, the use of rubber material can play a buffering role and reduce the shaking of the flow guide frame 1 when the cooling tower is working.

[0020] Furthermore, the triangular hollow structure is an equilateral triangle. Since the three sides of an equilateral triangle are of equal length and the three interior angles are the same, it can evenly distribute the external load when subjected to force, thereby improving its resistance to deformation. If the guide plate faces the flow with its bottom edge, the fluid on both sides can converge along the hypotenuse to the top corner, forming a concentrated flow stream. This is suitable for scenarios that require enhanced fluid impact force or concentration.

[0021] Furthermore, the apex of the triangular hollow structure is designed with rounded corners. If sharp corners are used, the fluid velocity will change abruptly and easily form local eddies. Using rounded transitions allows the fluid to "gradually flow around" the curved surface, reducing local eddies and increasing the stability of the device during use.

[0022] It should be noted that the specific installation methods and control methods of the cooling tower and sealing gasket 3 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
