Description

Technical Field

[0001] The utility model relates to the technical field of battery cooling equipment, in particular to a cooling device and a wind power gear box. Background Art

[0002] In the field of wind turbines, components within wind turbines, such as the gearbox, often heat up after prolonged operation. This is especially true in hot summer weather. This can cause the gearbox and other components to heat up, and the lubricating oil inside to heat up as well. This can lead to lubrication failure and shorten the gearbox's service life. Therefore, gearboxes are often equipped with cooling devices to dissipate heat.

[0003] Existing wind turbine gearboxes generally use cooling devices for heat dissipation. Since wind turbines are often located at high altitudes with strong winds, the use of air-cooled cooling devices improves resource utilization and reduces costs. However, existing gearbox cooling devices have problems such as dust screens that are too large and therefore poorly dustproof; dust screens that are insufficiently rigid and easily adhere to the radiator fins due to wind inhalation; and poor sealing between the dust screen and the radiator. These problems allow impurities to enter and cause blockage of the radiator fins. Especially during the season when willow catkins are flying, impurities such as catkins can become stuck in the narrow gaps of the radiator, affecting the ventilation of the fins and fan. This can also cause insufficient cooling of the lubricating oil in the gearbox, thus affecting the normal and continuous operation of the wind turbine gearbox.

[0004] Therefore, there is an urgent need for a cooling device and a wind turbine gearbox to solve the above technical problems. Utility Model Content

[0005] One purpose of the present utility model is to provide a cooling device that can improve the sealing and dustproof effect of the connection gap between the dustproof net and the radiator and the strength of the dustproof net itself, reduce the entry of impurities such as catkins, increase the service life of the cooling device, and reduce the cleaning frequency of the cooling device.

[0011] Optionally, the reinforcement structure includes a plurality of reinforcement ribs, and the plurality of reinforcement ribs are evenly distributed on the dustproof net.

[0012] Optionally, the shape of the reinforcement rib is straight, L-shaped, broken line, X-shaped or circular.

[0015] Optionally, the sealing and dustproof structure includes:

[0016] A fixing seat, the fixing seat being arranged on the fixing frame or the installation frame;

[0017] A brush is provided on the fixing seat and can be filled between the fixing frame and the installation frame to prevent the entry of impurities.

[0041] Please refer to the attached Figure 1 To the attached Figure 8 The utility model introduces a cooling device and a wind power gear box.

[0042] Please refer to Figures 1 to 3This embodiment provides a cooling device, which includes a heat sink 10, a dust screen 20, and a sealed dustproof structure 30. The heat sink 10 includes heat dissipating fins 11 for dissipating heat. A mounting frame 111 is provided on one side of the heat sink 10 where the heat dissipating fins 11 are provided. A fixed frame 21 of the dust screen 20 is fixedly connected to the mounting frame 111 of the heat sink 10. A reinforcing structure 22 is provided on the dust screen 20 to improve the structural strength of the dust screen 20. The sealed dustproof structure 30 is provided on the fixed frame 21 and / or the mounting frame 111 so that the sealed dustproof structure 30 fills the space between the fixed frame 21 and the mounting frame 111. The sealed dustproof structure 30 is used to prevent the entry of impurities.

[0043] The cooling device in this embodiment, first, improves the structural strength of the dustproof net 20 by adding a reinforcing structure 22 to the dustproof net 20, thereby avoiding the problem that the dustproof net 20 is easily affected by suction and stuck with the heat dissipation fins 11 due to insufficient strength; secondly, by adding a sealing dustproof structure 30 between the fixed frame 21 and the installation frame 111, the filling of the installation gap between the radiator 10 and the dustproof net 20 is achieved, thereby avoiding impurities such as catkins from entering the radiator 10 through the installation gap and causing blockage, ensuring the air intake of the cooling device, ensuring its good heat dissipation, improving the service life of the cooling device, and reducing the maintenance frequency of the internal structure of the cooling device.

[0044] Please refer to Figures 4 to 6 Specifically, the radiator 10 includes a shell 13, a cooling fan 12 and cooling fins 11. The cooling fan 12 and the cooling fins 11 are both arranged in the shell 13. The cooling fan 12 rotates to exchange heat inside and outside the shell 13. The cooling fins 11 are used to dissipate heat from the air exchanged with the gear box.

[0045] More specifically, a plurality of heat dissipation fins 11 are provided, and heat dissipation channels 112 are formed between adjacent heat dissipation fins 11 to achieve heat exchange between external air and the heat exchange medium of the gear box.

[0046] Optionally, the direction of the heat dissipation channel 112 is the same as the wind flow direction, so that the wind can dissipate heat through the heat dissipation channel 112 after entering, while also avoiding the blockage problem of some impurities.

[0047] Please refer to Figure 7 and Figure 8 In some embodiments, the dustproof net 20 is provided with a plurality of mesh holes 23 to enable the ingress and egress of air while also preventing the ingress and egress of some impurities.

[0048] Optionally, the dustproof net 20 is a metal dustproof net 20 to improve its structural strength.

[0049] In some embodiments, the reinforcement structure 22 on the dustproof net 20 includes a plurality of reinforcement ribs 221 , and the plurality of reinforcement ribs 221 are evenly distributed on the dustproof net 20 to uniformly improve the structural strength of the dustproof net 20 .

[0050] Optionally, the shape of the reinforcing rib 221 includes a straight line, an L shape, a broken line, an X shape or a circle, all of which can achieve the reinforcement effect on the dustproof net 20 without taking up too much space and affecting the air intake of the mesh 23.

[0051] Alternatively, the reinforcement structure 22 is integrally formed by stamping the dustproof net 20; or the reinforcement structure 22 is fixedly connected to the dustproof net 20, both of which can achieve the fixation of the reinforcement structure 22 to the dustproof net 20. In this embodiment, the reinforcement structure 22 is integrally formed by stamping the dustproof net 20, which is convenient to manufacture and simplifies the assembly process.

[0052] In some embodiments, in order to reduce the amount of impurities entering, the mesh number of the dustproof net 20 is increased so that the mesh number of the dustproof net 20 is greater than the designed mesh number. This reduces the aperture of the mesh 23, increases the impurity filtering amount of the dustproof net 20, and enhances the structural strength of the dustproof net 20.

[0053] Optionally, the mesh size of the dust screen 20 is M, and 15 mesh ≤ M ≤ 20 mesh. Existing dust screens 20 often have a mesh size of 10 mesh. This embodiment increases the mesh size of the dust screen 20 to within the above range, which not only ensures that the air intake meets the requirements, but also improves the ability to filter impurities and reduces the risk of clogging.

[0054] Please refer to Figure 5 and Figure 6 In some embodiments, the sealing and dustproof structure 30 includes a fixing seat 31 and a brush 32. The fixing seat 31 is arranged on the fixed frame 21 or the installation frame 111; the brush 32 is arranged on the fixing seat 31, and the brush 32 can be filled between the fixed frame 21 and the installation frame 111 to prevent the entry of impurities. The setting of the brush 32 can not only prevent the entry of impurities similar to catkins and improve the sealing and dustproof effect, but also facilitate cleaning and subsequent disassembly and maintenance. Of course, in other embodiments, the sealing and dustproof structure 30 is a self-adhesive strip, sealing strip or rubber strip, which can also achieve the sealing and dustproof effect of the installation gap, and the sealing effect is strong, but it needs to be replaced during maintenance, and the maintenance cost is high.

[0055] Specifically, the fixing base 31 and the fixed frame 21 or the fixing base 31 and the installation frame 111 are connected by bonding, bolting or snapping to fix the sealing and dustproof structure 30. Preferably, the fixing base 31 and the fixed frame 21 or the fixing base 31 and the installation frame 111 are connected by snapping to facilitate disassembly.

[0056] Optionally, a mounting groove 311 is provided on the fixing seat 31 , and the brush 32 is fixed in the mounting groove 311 .

[0057] Specifically, the sealing dustproof structure 30 is arranged on the mounting frame 111 , that is, on the radiator 10 , which facilitates the removal of the dustproof net 20 and the cleaning of the sealing dustproof structure 30 .

[0058] Optionally, two sealing and dustproof structures 30 are symmetrically arranged, and the two fixing seats 31 are respectively arranged on the fixed frame 21 and the installation frame 111, and at least parts of the two brushes 32 are staggered with each other. This arrangement increases the dustproof sealing ability at the installation gap between the radiator 10 and the dustproof net 20, and further reduces the clogging of impurities.

[0059] Furthermore, the cooling device further includes a fixing bracket 40 , which is used for connecting the radiator 10 and the dustproof net 20 and fixing the cooling device to the outside.

[0060] This embodiment further provides a wind turbine gearbox, which includes the cooling device described in any of the above solutions. By adopting the cooling device, the wind turbine gearbox has better operating performance, longer service life, and is easier to maintain.

[0061] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
