Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology, and more specifically, to a cabin heat dissipation system and a wind turbine generator set. Background Art

[0002] With the development of the wind power industry, wind turbines are increasingly tending to be large-scale in design. At the same time, in order to reduce the cost of the whole machine as much as possible, a cabin design mode with a box-type transformer placed on top is proposed, that is, the transformer and converter originally placed on the ground are placed on the cabin, thereby reducing the cost of cables, civil engineering, etc. The current mainstream box-type transformer placed on top structure considers placing the box-type transformer at the rear of the cabin, the side of the cabin, and the top of the cabin. At the same time, the cooling system of the cabin after the box-type transformer is placed on top still adopts the conventional solution, that is, the air enters from the bottom of the main cabin cover and the air is discharged from the rear of the main cabin cover.

[0003] However, existing box transformers generally need to be placed in a separate cabin, and the box transformer will generate a lot of heat when the wind turbine is running. The use of traditional heat dissipation solutions will cause a large amount of heat to accumulate inside the box transformer cabin, causing the cabin cover to be in a long-term high temperature environment, which will have a great impact on the life of the cabin cover and create a fire hazard.

[0004] Therefore, how to solve the problem that a separate box-type transformer compartment cannot dissipate heat is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a cabin heat dissipation system, which realizes heat dissipation of a separate box-type transformer cabin by arranging air inlets and air outlets in the separate box-type transformer cabin.

[0006] Another object of the present invention is to provide a wind turbine generator set including the above-mentioned nacelle heat dissipation system, which can improve the overall heat dissipation effect and extend the service life.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The core of the present invention is to provide a cabin cooling system, which can achieve heat dissipation of a separate cabin by setting an air inlet 4 and an air outlet 5 in the separate cabin. Another core of the present invention is to provide a wind turbine generator set including the cabin cooling system, which can improve the overall heat dissipation effect and extend the service life.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 A cabin cooling system includes a main cabin 1, a first box-type transformer cabin 2 and a second box-type transformer cabin 3.

[0043] Specifically, the first box transformer cabin 2 and the second box transformer cabin 3 are both arranged on one side of the main cabin 1, and the main cabin 1, the first box transformer cabin 2 and the second box transformer cabin 3 are all provided with an air inlet 4 and an air outlet 5. By arranging the air inlet 4 and the air outlet 5 on the main cabin 1, the first box transformer cabin 2 and the second box transformer cabin 3, heat dissipation of the main cabin 1, the first box transformer cabin 2 and the second box transformer cabin 3 can be achieved to avoid heat concentration in a single box transformer cabin, resulting in the cabin cover of the main cabin 1 being in a long-term high temperature environment, shortening the life of the cabin cover, and creating a fire hazard. The air inlet 4 is provided with a filter device 6 for filtering cold air, and the cold air is filtered by the filter device 6 to avoid dust particles and other pollutants being carried in the cold air entering the cabin.

[0044] The cabin cooling system arranged in the above manner can effectively reduce the temperature of the cabin of the transformer by separately arranging air inlets 4 and air outlets 5 in the first transformer cabin 2 and the second transformer cabin 3 to achieve heat dissipation of the separate transformer cabins. A filter device 6 is arranged at the air inlet 4 to improve the quality of air entering the cabin and reduce the influence of dust in the cabin, thereby reducing fire hazards and further improving the safety of the entire machine.

[0045] Please refer to Figure 1 and Figure 4 The first transformer cabin 2 includes a first transformer rack 21 and a first transformer cabin cover 22 covering the outer periphery of the first transformer rack 21 . The first transformer rack 21 is provided with an air inlet 4 , and the air inlet 4 is provided with a filter device 6 . The outer side of the first transformer cabin cover 22 is provided with an air outlet 5 , and the air outlet 5 is provided with a first air outlet louver 23 .

[0046] It should be noted that air enters the first transformer cabin 2 through the air inlet 4, performs heat exchange in the first transformer cabin 2, and the hot air after heat exchange flows out through the first air outlet louver 23 of the air outlet 5 to achieve heat dissipation for the first transformer cabin 2.

[0047] Please refer to Figure 2 and Figure 5 A fan 24 is further provided in the first transformer cabin 2 , an air outlet of the fan 24 is sealed and connected to the first air outlet louver 23 , and a drainage hole 25 is provided below the fan 24 in the first transformer frame 21 .

[0048] It can be understood that a fan 24 is arranged in the first transformer cabin 2, and the fan 24 is used to further accelerate the air circulation in the first transformer cabin 2, and the hot air in the first transformer cabin 2 is discharged through the first air outlet louver 23. It should be noted here that the space from the fan 24 to the first air outlet louver 23 must be closed to avoid hot air backflow. At the same time, a drainage hole 25 is added below the closed space to prevent water vapor from backflowing and damaging the transformer equipment in the first transformer cabin 2.

[0049] The first air outlet louver 23, the fan 24 and the first transformer nacelle cover 22 are connected by bolts.

[0050] Please refer to Figure 1 and Figure 6 The second transformer cabin 3 includes a second transformer rack 31 and a second transformer cabin cover 32 covering the outer periphery of the second transformer rack 31 . The second transformer rack 31 is provided with an air inlet 4 , and the air inlet 4 is provided with a filter device 6 . The outer side of the second transformer cabin cover 32 is provided with an air outlet 5 , and the air outlet 5 is provided with a second air outlet louver 33 .

[0051] It should be noted that air enters the second transformer cabin 3 through the air inlet 4, performs heat exchange in the second transformer cabin 3, and the hot air after heat exchange flows out through the second air outlet louver 33 of the air outlet 5 to achieve heat dissipation of the second transformer cabin 3. The second air outlet louver 33 is connected to the second transformer cabin cover 32 by bolts.

[0052] On the basis of the above embodiment, an air guide cover 34 is further provided in the second box transformer cabin 3, one end of the air guide cover 34 is connected to the box transformer structure 35 in the second box transformer cabin 3, and the other end of the air guide cover 34 is connected to the second air outlet louver 33, and the two ends of the air guide cover 34 are clamped and fixed by a tensioning device.

[0053] It can be understood that one end of the air guide cover 34 is fixed to the second air outlet louver 33 with bolts, the middle section is fixed with a tensioning device, and the other end of the air guide cover 34 is fixed to the box-type transformer structure 35 with bolts. By directly connecting the air guide cover 34 and the box-type transformer structure 35, the hot air generated by the box-type transformer structure 35 can be discharged directly from the second air outlet louver 33 through the air guide cover 34.

[0054] The first transformer nacelle cover 22 and the second transformer nacelle cover 32 are used to contain and protect the corresponding transformers.

[0055] Please refer to Figure 1 The main engine room 1 includes a main frame 11 and a main engine room cover 12 covering the outer periphery of the main frame 11. An air inlet 4 is provided at the bottom of the main frame 11, and a filter device 6 is provided at the air inlet 4. An air outlet 5 is provided at the tail of the main frame 11, and the air outlet 5 is integrally formed with the main engine room cover 12.

[0056] It should be noted that the circulating air in the main engine nacelle cover 12 enters the cabin from the air inlet 4 and is discharged from the air outlet 5 after passing through the main bearing, the gear box and the generator.

[0057] Please refer to Figure 7The first box transformer nacelle cover 22 and the second box transformer nacelle cover 32 are both connected to the main nacelle cover 12 through flanges. A communicating circulation hole 7 is provided on the first box transformer nacelle cover 22 and the main nacelle cover 12. The circulation hole 7 is arranged close to the top of the first box transformer nacelle cover 22 and the main nacelle cover 12. A communicating opening 8 is provided on the second box transformer nacelle cover 32 and the main nacelle cover 12.

[0058] It is understandable that the thermal simulation found that heat is concentrated at the top of the second box transformer cabin 3. Therefore, in addition to the bottom air inlet 4, a circulation hole 7 is opened at the top of the second box transformer cabin cover 32 and the main cabin cover 12 at the air inlet position of the second box transformer cabin 3 to strengthen air flow exchange. At the same time, a fan 24 is used to further accelerate air circulation and discharge hot air through the first air outlet louver 23. In terms of air flow, an air flow opening 8 is opened between the second box transformer cabin cover 32 and the main cabin cover 12 to strengthen air flow exchange.

[0059] During the cabin heat cycle, cooling air enters the corresponding cabin from the air inlets 4 of the main cabin 1, the first box-type transformer cabin 2 and the second box-type transformer cabin 3 after being filtered, and is discharged from the respective air outlets 5 after heat exchange in the cabin.

[0060] Please refer to Figure 8 In one embodiment, the filter device 6 includes a grille 61 and a first filter 62 , the grille 61 and the first filter 62 are connected by bolts, and the first filter 62 is fixed to the air inlet 4 by a first clamping structure 63 .

[0061] It should be noted that the grille 61 is connected to the first filter 62 by bolts, and the first filter 62 is connected to the main cabin 1 and the first box transformer cabin 2 by a first clamping structure 63. When the grille 61 is removed, quick disassembly can be achieved by unscrewing the nuts.

[0062] Please refer to Fig. 9 In another embodiment, the filtering device 6 includes a second filter 64 , the second filter 64 is disposed at the air inlet 4 through a second pressing structure 65 , and the second filter 64 is fixed to the air inlet 4 through a clamp 66 .

[0063] It can be understood that the second filter 64 is partially compressed by the second compression structure 65, and the second filter 64 can be pulled out or fixed by controlling the opening and closing of the clamp 66, so as to achieve rapid maintenance.

[0064] In the present application, the filtering device 6 includes the above two solutions, but in practical applications, there is no limitation to this, as long as the above technical effects can be achieved.

[0065] In summary, the cabin heat dissipation system provided by the present invention can effectively reduce the temperature of the transformer cabin, avoid the cabin cover from being affected by high temperature, and can also improve the air quality, reduce the impact of dust in the cabin, reduce fire hazards, and improve the safety of the entire machine.

[0066] In addition to the cabin cooling system disclosed in the above embodiments, the present invention also provides a wind turbine generator set including the above cabin cooling system.
