Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a wind turbine with rapid heat dissipation. Background Technology

[0002] There are two heat sources for wind turbines. The first is the heat generated by the generator during its rotation and the second is the heat generated by sunlight shining on the generator's casing. Especially in the high-temperature environment of summer, the simultaneous generation of both heat sources seriously affects the normal operation of wind turbines.

[0003] To dissipate heat, some wind turbines are equipped with fans. For example, utility model application number 2021233658440 discloses a wind turbine with rapid heat dissipation function. When the exhaust component is working, it evenly extracts the heat generated by the generator body inside the cylinder through the heat absorption cavity, and the air intake component quickly inputs the outside air into the cylinder to achieve the purpose of rapid cooling. Although the heat dissipation performance is enhanced, the exhaust fan in the exhaust component consumes electricity, which is costly and needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a wind turbine generator with rapid heat dissipation, thereby enhancing the heat dissipation effect and reducing energy consumption.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A wind turbine with rapid heat dissipation includes: a horizontal axis generator, a guide tube, an air distribution pipe, and a support pipe. The guide tube is horizontally suspended above the support pipe. The horizontal axis generator is disposed in the guide tube. The air distribution pipe is vertically disposed below the horizontal axis generator. The air distribution pipe penetrates downward through the guide tube and is connected to the support pipe. The lower part of the support pipe is provided with air inlets at intervals. The air distribution pipe is provided with a number of air outlets located in the guide tube in a circular array.

[0007] The outer surface of the guide tube is provided with a reflective coating.

[0008] The horizontal axis generator is provided with a rotating shaft extending to the front of the guide tube, and blades are arranged in a ring array on the rotating shaft.

[0009] The horizontal axis generator housing is provided with heat dissipation fins at intervals.

[0010] The top of the gas distribution pipe is provided with a first flange that connects to the bottom of the horizontal shaft generator.

[0011] The gas distribution pipe is provided with a second flange at its bottom, and the support pipe is provided with a third flange at its top, which is connected to the second flange.

[0012] The bottom of the guide tube is provided with a through hole corresponding to the air distribution pipe, and a limiting sleeve is provided at the bottom of the through hole and fitted onto the lower part of the air distribution pipe.

[0013] The beneficial effects of this utility model are as follows: A wind turbine with rapid heat dissipation uses a guide tube to shield the horizontal axis generator from sunlight, preventing it from overheating. Utilizing the principles of rising hot airflow and the chimney effect, the heat generated by the horizontal axis generator during operation heats the air inside the guide tube, causing the air to rise and escape from both ends of the guide tube. Air is drawn from the air distribution pipe and support pipe through the air outlet, while fresh air is replenished from the outside through the air inlet at the bottom of the support pipe. Fresh air enters the support pipe and air distribution pipe, and then enters the guide tube through the air outlet, enhancing airflow and improving the heat dissipation effect of the horizontal axis generator. Moreover, it eliminates the need for an exhaust fan, reducing costs and energy consumption. Attached Figure Description

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

[0015] Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0016] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 The wind turbine generator with rapid heat dissipation shown includes: a horizontal axis generator 2, a guide tube 4, an air distribution pipe 10, and a support pipe 1. The guide tube 4 is horizontally suspended above the support pipe 1. The support pipe 1 is made of tapered steel pipe, which has high strength and good support stability.

[0018] A horizontal axis generator 2 is installed in a guide tube 4. The horizontal axis generator 2 has a rotating shaft 8 extending to the front of the guide tube 4. The rotating shaft 8 has a ring array of blades 7. The blades 7 drive the rotating shaft 8 to rotate under the power of the wind, and generate electricity through the horizontal axis generator 2.

[0019] In this embodiment, the horizontal axis generator 2 is concentrically arranged in the guide tube 4, and a gap is left between the horizontal axis generator 2 and the inner wall of the guide tube 4 to facilitate airflow and remove the heat from the horizontal axis generator 2. In addition, heat dissipation fins 6 are spaced apart on the outer shell of the horizontal axis generator 2. The heat dissipation fins 6 increase the contact area with the airflow, which is beneficial to the heat dissipation of the horizontal axis generator 2.

[0020] like Figure 1As shown, the guide tube 4 shields the housing of the horizontal axis generator 2 from sunlight, preventing the generator 2 from overheating due to sunlight exposure. In this embodiment, a reflective coating 5 is provided on the outer surface of the guide tube 4. The reflective coating 5 can reflect sunlight, reducing the temperature rise of the guide tube 4 and further reducing the adverse effects of sunlight on the heat dissipation of the horizontal axis generator 2.

[0021] The gas distribution pipe 10 is vertically positioned below the horizontal shaft generator 2. In this embodiment, the top of the gas distribution pipe 10 is provided with a first flange 11 that connects to the bottom of the horizontal shaft generator 2. The first flange 11 is welded to the top of the gas distribution pipe 10, resulting in a robust structure. The first flange 11 can be connected to the bottom of the horizontal shaft generator 2 using screws, facilitating assembly.

[0022] The air distribution pipe 10 extends downward through the guide tube 4 and connects to the support pipe 1, such as... Figure 2 As shown, the bottom of the air distribution pipe 10 is provided with a second flange 12, and the top of the support pipe 1 is provided with a third flange 13 connected to the second flange 12. The second flange 12 and the third flange 13 are connected by screws, which realizes the connection between the air distribution pipe 10 and the support pipe 1, and the structure is solid.

[0023] In addition, the bottom of the guide tube 4 is provided with a through hole corresponding to the air distribution pipe 10. A limiting sleeve 9 is provided at the bottom of the through hole and is fitted onto the lower part of the air distribution pipe 10. The top of the limiting sleeve 9 is welded to the guide tube 4, ensuring structural stability. The bottom of the limiting sleeve 9 contacts the second flange 12 to limit the height of the guide tube 4. The guide tube 4 and the air distribution pipe 10 can be fixed with screws to prevent relative torsion of the guide tube 4 on the outside of the air distribution pipe 10, thereby improving the structural stability of the guide tube 4.

[0024] For ease of installation, the guide tube 4 and the limiting sleeve 9 each adopt a two-part structure. For example, the guide tube 4 includes two horizontally placed semi-circular curved plates. The two semi-circular curved plates are connected and fixed by screws to form the guide tube 4. Disassembly is also relatively convenient, which is beneficial to the maintenance of the horizontal shaft generator 2.

[0025] like Figure 1 As shown, air inlets 3 are spaced apart at the lower part of the support tube 1, such as... Figure 2 As shown, the air distribution pipe 10 has several air outlets 14 arranged in a ring array within the guide tube 4. The air inlet 3 and the air outlets 14 are connected to the air distribution pipe 10 via the support pipe 1. Utilizing the principle of rising hot airflow and the chimney effect, the heat generated by the horizontal axis generator 2 during operation heats the air inside the guide tube 4, causing the air in the guide tube 4 to rise and escape from both ends of the guide tube 4. The air outlets 14 then draw air from the air distribution pipe 10 and the support pipe 1, allowing the air inside the air distribution pipe 10 and the support pipe 1 to enter the guide tube 4 for cooling the horizontal axis generator 2.

[0026] Fresh air is introduced from the outside through the air inlet 3 at the bottom of the support pipe 1 to replenish the air in the air distribution pipe 10 and the support pipe 1. The fresh air enters the support pipe 1 and the air distribution pipe 10, and then enters the guide tube 4 through the air outlet 14, which enhances the air flow and improves the heat dissipation effect of the horizontal shaft generator 2. Moreover, there is no need for an exhaust fan to drive it, which reduces costs.

[0027] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
