Description

Technical Field

[0001] This utility model relates to a water turbine fan device that does not require a motor to drive the impeller. It features an optimized and uniquely designed shroud and support structure, ensuring the stability of the entire device and a large and uniform air volume. Background Technology

[0002] Existing cooling tower fans are mainly installed inside the cooling tower and consist primarily of an impeller and a motor. The high-frequency noise generated by the motor and fan propagates far outwards, making it difficult to effectively control the noise. Furthermore, long-term operation can easily burn out the motor. To effectively achieve efficient, energy-saving, and low-noise operation of cooling towers, existing technologies mainly optimize the design of the cooling tower fan impeller and rationally select the drive motor. However, the current structure still cannot solve the problems of high noise, low air volume, and uneven airflow. Utility Model Content

[0003] The purpose of this utility model is to provide a water turbine fan device, and the technical problem to be solved is: how to make the water turbine fan device operate more stably, with less noise and to ensure sufficient and uniform air intake.

[0004] A water turbine fan includes a shroud, a support frame, a water turbine, a drive shaft, an impeller, and a fan casing. The shroud is hollow inside and has openings at both ends. The internal space of the shroud narrows from one end to the opposite end. The water turbine is fixed inside the shroud by a support frame installed on the inner wall of the shroud. The support frame is generally flat. The water turbine is assembled with the impeller via the drive shaft. The impeller is located inside the fan casing, which is fixed to the shroud. One end of the support frame is installed next to the bend between the top and side of the shroud.

[0005] The wind shield is a polygonal column structure.

[0006] The polygonal column structure is a rectangular column structure.

[0007] The rectangle is a rectangular shape.

[0008] One of the openings at both ends of the fan cover is a rectangular opening and is assembled with the cooling tower, while the other opening is a circular opening and is assembled with the fan duct. The lateral area of ​​the rectangular opening is greater than that of the circular opening.

[0009] The bracket has four parts, each bracket is installed at an angle between the wind cover and the water turbine.

[0010] The turbine in question is a spiral-type turbine.

[0011] The air duct is installed at the circular opening of the air cover, and the diameter of the air duct corresponds to the circular opening.

[0012] The water turbine has an inlet and an outlet, both of which are equipped with water pipes, which are also fixed to the wind cover.

[0013] The ventilation duct is equipped with a grid.

[0014] The beneficial effects of this utility model are as follows: by designing the fan shroud, it can be installed on the top of the cooling tower and above the cooling coil of the cooling tower, thus improving the cooling effect. The fan shroud adopts a constricted, trumpet-shaped structure, which ensures that the air pressure inside the fan shroud is as uniform as possible and ensures a wider air intake area and a larger air intake volume. By designing the bracket to be flat, the obstruction of the air intake is reduced. At the same time, the bracket is installed next to the bend, which has stronger rigidity than other positions, thus ensuring the installation stability of the bracket. Attached Figure Description

[0030] Please refer to Figures 1 to 6 The water turbine fan shown in the diagram mainly consists of components such as a fan shroud 1, a support frame 2, a water turbine 3, a drive shaft 4, an impeller 5, and a fan casing 6. The fan shroud 1 houses the support frame 2 and the water turbine 3, while also supporting and fixing the impeller 5 and the fan casing 6. The support frame 2 secures the water turbine 3. The water turbine 3 drives the impeller 5 to rotate via the drive shaft 4 under the influence of water flow. The impeller 5 and the fan casing 6 draw in air to cool the cooling tower. In practical applications, the local shapes, interlocking structures, and specific quantities of these components can be further optimized according to actual needs, and other components can also be added.

[0031] As shown in the figure, the fan shroud 1 adopts a hollow rectangular three-dimensional column design, presenting a shape that is wider at the bottom and narrower at the top. As shown in the figure, the internal space of the fan shroud 1 is tapered or flared from one end to the opposite end. The rectangle at the bottom of the figure is rectangular, while the rectangle at the top can be rectangular or square. Both the top and bottom ends have openings. The lower opening is rectangular and is used to install on the top of the cooling tower, directly above the coil, thereby improving the heat dissipation effect. The upper opening is circular and is used to configure the impeller 5 and the fan duct 6. As shown in the figure, the horizontal area of ​​the rectangular opening is larger than that of the circular opening. Through the above-mentioned structure design of being wider at the bottom and narrower at the top, firstly, it ensures sufficient air intake and stable and uniform air pressure, avoiding the loss of air volume and air pressure caused by the obstruction of the water turbine 3 in the air supply path. Secondly, it forms a large bending angle, thereby forming strong installation strength at the bending point 11, thus providing installation strength for the subsequent support 2 and preventing deformation of the water turbine installation position. The fan cover 1 has holes drilled at the top and bottom of its side wall to facilitate the installation of components such as the water inlet pipe 71 and the water outlet pipe 72. In practical applications, the specific shape of the fan cover 1 can be further optimized or other designs can be adopted as needed, such as designing it as a regular or irregular polygonal column or cylinder, or a flat-topped cone.

[0032] The brackets 2 shown in the figure are four in number and are evenly and obliquely installed between the wind shroud 1 and the water turbine 3 to secure the water turbine 3. Each bracket 2 has a flat structure that aligns with the airflow direction to avoid obstructing the airflow. One side of the bracket 2 is positioned next to the bend 11 between the top and side of the wind shroud 1, while the other side has a fastening assembly 21 that secures the water turbine 3. This fastening assembly 21 is a combination of a conventional frame and fasteners. In practical applications, the overall structure, quantity, and specific assembly of the brackets 2 with the wind shroud 1 and water turbine 3 can be further optimized as needed.

[0033] The water turbine 3 shown in the figure is an existing component, employing a volute-type design. This turbine 3 has an inlet 31 and an outlet 32, with corresponding water pipes shown as inlet pipe 71 and outlet pipe 72. These water pipes are installed on the fan shroud 1 as described above, thus utilizing the cooling tower's own water flow to drive the turbine 3. The turbine 3 is horizontally positioned, allowing the drive shaft 4 to be arranged longitudinally, facilitating the installation of the impeller 5 and its similar horizontal placement. In practical applications, other configurations of the aforementioned water turbine 3 can also be used.

[0034] The impeller 5 in the figure can be of a conventional design and is located inside the air duct 6. This impeller 5 blows the air inside the cooler to the outside.

[0035] The air duct 6 in the figure is a hollow cylindrical structure, which is fixed to the circular opening at the top of the shroud 1. The inner diameter of the air duct 6 corresponds to the circular opening to ensure sufficient air intake. As with existing technology, a grid 8 can be installed on the air duct 6 to protect the impeller 5.
