Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular, to a heat dissipation component and a wind turbine of a wind turbine unit. Background Art

[0002] In the related art, as the power of wind turbine units increases, the heat generation of heat-generating components such as gearboxes, motors, or converters becomes increasingly large. Some manufacturers use an air-water cooling system for heat dissipation, and connect several heat dissipation plates in a row and place them in the external environment on the top of the nacelle. The natural wind blows through the heat dissipation plates with coolant inside to achieve convective heat transfer.

[0003] The existing outboard water-cooling structure of the fan uses several heat dissipation plates. The heat dissipation plates are in the same plane and all face the front of the nacelle. However, since the air flow passing through the heat dissipation plates needs to pass through the rotating blades first, the air flow reaches the heat dissipation plates after being disturbed and blocked by the blades. The heat dissipation plate structure adopted in the prior art arranges all the heat dissipation plates in the same direction and is parallel to the YZ plane of the nacelle, which cannot ensure the heat dissipation efficiency of the heat dissipation plates, and the air flow is easily deflected from the heat dissipation plates after being disturbed and blocked by the blades, resulting in a decrease in the air volume passing through the heat dissipation plates and further reducing the heat dissipation efficiency.

[0039] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts belong to the scope of protection of the present invention.

[0040] In the related art, with the increase in the power of wind turbines, the heat generation of heat-generating components such as gearboxes, motors or converters becomes increasingly large. Some manufacturers use an air-water cooling system for heat dissipation, and connect several heat dissipation plates in a row and place them in the external environment on the top of the machine cabin, relying on natural wind blowing through the heat dissipation plates containing coolant to achieve convective heat transfer.

[0041] The existing out-of-cabin water-cooling structure of wind turbines uses several heat dissipation plates. The heat dissipation plates are in the same plane and all face the front of the machine cabin. However, since the air flow passing through the heat dissipation plates needs to pass through the rotating blades first, the air flow reaches the heat dissipation plates after being disturbed and blocked by the blades. The heat dissipation plate structure adopted in the prior art arranges all the heat dissipation plates in the same direction and is parallel to the YZ plane of the machine cabin, which cannot ensure the heat dissipation efficiency of the heat dissipation plates, and the air flow is likely to deviate from the heat dissipation plates after being disturbed and blocked by the blades, resulting in a decrease in the air volume passing through the heat dissipation plates and further reducing the heat dissipation efficiency.

[0042] As Figures 1 to 10 shown, to solve the above technical problems in the related art, a heat dissipation component of a wind turbine is proposed in the first aspect embodiment of the present invention. The heat dissipation component includes an installation frame 1 and a heat dissipation plate 2.

[0043] The heat dissipation plate 2 is internally provided with a cooling pipeline (not shown in the figure). The heat dissipation plate 2 is used for convecting with natural wind to realize the heat dissipation of the coolant in the cooling pipeline.

[0044] A plurality of heat sinks 2 are mounted on the mounting frame 1 ; the plurality of heat sinks 2 are located on the leeward side of the wind turbine and are all arranged relative to the blades 4 of the wind turbine, and the plurality of heat sinks 2 together define a wind collecting space 13 protruding away from the blades 4 .

[0045] Compared with the heat sink 2 structure in the related art, the heat sink assembly proposed in the present invention has multiple heat sinks 2 in the assembly that are not limited to the YZ plane of the cabin, and the multiple heat sinks 2 jointly define a wind gathering space 13 that protrudes toward the direction away from the blades 4. In this way, on the one hand, under the wind guiding and wind gathering effect of the wind gathering space 13, the wind flow that has been disturbed and blocked by the blades 4 can be collected in the wind gathering space 13, thereby increasing the total air volume passing through the heat sink assembly. On the other hand, since the heat sink 2 is not limited to the YZ plane of the cabin, the air volume flowing through a single heat sink 2 is also increased. In summary, the heat sink assembly according to the embodiment of the present invention achieves the effect of gathering the airflow quality through the wind gathering space 13, increases the air flow through the heat sink 2, and improves the cooling and heat dissipation efficiency of the heat sink assembly. In addition, the structure is simple and easy to implement and maintain.

[0046] It should be explained that the heat sink 2 provided in the heat sink assembly of the present invention is not a simple plate, but the shape of the heat sink 2 is plate-shaped as a whole. Among them, the heat sink 2 is built with a cooling pipe for the circulation of coolant, and a heat dissipation gap (not shown in the figure) is formed on the surface of the heat sink 2, and the heat dissipation gap is connected to the outer surface of the cooling pipe. When natural wind blows toward the heat sink 2, the wind flows through the heat sink 2 from the heat dissipation gap, and takes away the heat of the coolant in the cooling pipe during the flow, thereby achieving the effect of heat dissipation.

[0047] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the blades 4 of the wind turbine rotate around the rotating shaft to form a rotating surface 5, the length direction of the mounting frame 1 is oriented along the diameter direction of the rotating surface 5 and is formed with an opposite first end 11 and a second end 12. A plurality of heat dissipation plates 2 are spaced apart in the direction from the first end 11 to the second end 12.

[0048] According to some embodiments of the present invention, the heat dissipation assembly can form the wind gathering space 13 through a plurality of heat dissipation plates 2 arranged obliquely to each other, or the heat dissipation assembly can also form the wind gathering space 13 through a plurality of heat dissipation plates 2 arranged staggered to each other, or the heat dissipation assembly can also form the wind gathering space 13 through a plurality of heat dissipation plates 2 arranged staggered to each other and obliquely to each other. The present invention does not impose any special restrictions here, as long as the heat dissipation assembly can form the wind gathering space 13 protruding in the direction away from the blade 4. For ease of understanding, multiple embodiments of the heat dissipation assembly forming the wind gathering space 13 will be described in detail below.

[0049] like Figure 2As shown, according to an embodiment of the present invention, all the heat dissipation plates 2 are inclined relative to the rotating surface 5. Among them, the heat dissipation plates 2 adjacent to the first end 11 extend in a direction away from the rotating surface 5 and are inclined towards the second end 12, and the heat dissipation plates 2 adjacent to the second end 12 extend in a direction away from the rotating surface 5 and are inclined towards the first end 11, so as to form a wind gathering space 13.

[0050] In this embodiment, the heat dissipation plates 2 located on both sides of the mounting frame 1 are inclined towards the central part of the mounting frame 1, so that a wind gathering space 13 protruding outwards is formed on one side of the heat dissipation assembly close to the rotating surface 5. The wind gathering space 13 is generally arc-shaped and protrudes towards the side away from the rotating surface 5. In this way, the wind blowing from one side of the rotating surface 5 will be collected in the wind gathering space 13, thereby increasing the air volume passing through the heat dissipation assembly.

[0051] For example Figure 2 As shown, the heat dissipation assembly is installed at the rear side of the blade 4. The left end of the mounting frame 1 is the first end 11, the right end of the mounting frame 1 is the second end 12, and the number of heat dissipation plates 2 is six and they are arranged in sequence in the left-right direction. The four heat dissipation plates 2 on the left side are all inclined to the right, and in the direction from left to right, the inclination angles of the four heat dissipation plates 2 relative to the left-right direction decrease in sequence; the two heat dissipation plates 2 on the right side are all inclined to the left, and in the direction from right to left, the inclination angles of the two heat dissipation plates 2 relative to the left-right direction decrease in sequence.

[0052] As Figure 3 As shown, further, in order to improve the wind gathering effect of the wind gathering space 13, all the heat dissipation plates 2 are staggered in the direction perpendicular to the rotating surface 5. And in the direction of the first end 11 or the second end 12 towards the center of the mounting frame 1, the distance between the center of each heat dissipation plate 2 and the rotating surface 5 increases continuously, so as to form the wind gathering space 13.

[0053] In this embodiment, the heat dissipation plates 2 are staggered in the front-rear direction (i.e., the direction perpendicular to the rotating surface 5), and the distribution structure of the heat dissipation plates 2 is that the closer the heat dissipation plate 2 is to the center of the mounting frame 1, the farther the distance from the rotating surface 5. In this way, the original wind gathering space 13 becomes larger under the distribution structure of the staggered heat dissipation plates 2. That is to say, the heat dissipation assembly in this embodiment simultaneously limits a larger range of wind gathering space 13 through the inclined structure of the heat dissipation plates 2 themselves and the staggered distribution structure among multiple heat dissipation plates 2, thereby further improving the wind gathering ability of the wind gathering space 13.

[0054] For example Figure 3As shown in the figure, the heat dissipation component is installed at the rear side of the blade 4. The left end of the installation frame 1 is the first end 11, and the right end of the installation frame 1 is the second end 12. The number of heat dissipation plates 2 is six, and they are arranged in sequence in the left-right direction. The four heat dissipation plates 2 on the left side are all inclined to the right, and in the direction from left to right, the inclination angles of the four heat dissipation plates 2 relative to the left-right direction decrease in sequence; the two heat dissipation plates 2 on the right side are all inclined to the left, and in the direction from right to left, the inclination angles of the two heat dissipation plates 2 relative to the left-right direction decrease in sequence.

[0055] In addition, in the direction from the left end of the installation frame 1 to the center, the distance between the heat dissipation plate 2 and the rotating surface 5 gradually increases, and this distance reaches the maximum value at the fourth heat dissipation plate 2 counted from the left; in the direction from the right end of the installation frame 1 to the center, the distance between the heat dissipation plate 2 and the rotating surface 5 gradually decreases.

[0056] It should be noted that if the heat dissipation plate 2 is inclined relative to the rotating surface 5, not only can the technical effects described in the above embodiments be brought, but also the effect of additionally improving the heat dissipation efficiency can be achieved. The specific explanation is as follows:

[0057] In the related art, it can be understood that since the air flow flowing through the heat dissipation plate 2 needs to pass through the disturbance and block of the rotating blade 4 first before reaching the heat dissipation plate 2, the inflow angle of the air flow passing through the heat dissipation plate 2 is dynamically changing, and the inflow angles of the air flow flowing through each heat dissipation plate 2 at different wind speeds and different wind turbine rotation speeds are also different.

[0058] In response to this, the heat dissipation component proposed by the present invention can solve the above technical problems by inclining the heat dissipation plate 2. Specifically, the inventor found through multiple experiments and summaries that if each heat dissipation plate 2 in the heat dissipation component is set with different inclination angles, the oncoming air flow disturbed by the blade 4 can blow over the surface of the heat dissipation plate 2 as vertically as possible as a whole to obtain the maximum air flow quality, so that the heat dissipation efficiency of the cooling system is the highest.

[0059] For example, in the case where the number of heat dissipation plates 2 is fifteen, the inventor obtained the following conclusion through experiments and simulations: if the inclination angles of the fifteen heat dissipation plates 2 relative to the rotating surface 5 are set as 49°, 52°, -57°, -54°, -51°, -48°, -43°, -27°, -18°, -11°, -5°, -3°, 3°, 16° and 24° in sequence from left to right, the air volume passed through each heat dissipation plate 2 can be maintained in a state close to the maximum air volume, that is, the heat dissipation efficiency of each heat dissipation plate 2 can almost reach the optimal heat dissipation efficiency at this time. Of course, the above embodiment is only one of many embodiments of the present invention and does not constitute a limitation on the heat dissipation component.

[0060] In summary, by obliquely arranging the heat dissipation plate 2, the heat dissipation component of the present invention can form a wind gathering space 13 and is also conducive to the unit obtaining the maximum comprehensive air flow under the combined action of the oncoming wind disturbed by the rotating blades 4 of the wind turbine during the periodic rotation operation of the wind turbine blades 4, thereby achieving the highest heat dissipation efficiency.

[0061] As Figure 4 shown, according to another embodiment of the present invention, all the heat dissipation plates 2 are arranged parallel to the rotating surface 5. And in the direction of the first end 11 or the second end 12 towards the center of the mounting frame 1, the distance between the center of each heat dissipation plate 2 and the rotating surface 5 continuously increases to form a wind gathering space 13.

[0062] In this embodiment, the heat dissipation plates 2 are arranged staggeredly in the front-back direction (i.e., the direction perpendicular to the rotating surface 5), and the distribution structure of the heat dissipation plates 2 is that the heat dissipation plates 2 closer to the center of the mounting frame 1 are farther away from the rotating surface 5. Different from the obliquely arranged heat dissipation plates 2 above, the heat dissipation plates 2 in the heat dissipation component of this embodiment are all arranged parallel to the rotating surface 5. It can be understood that the structure of the heat dissipation plates 2 introduced in this embodiment can also define a relatively large wind gathering space 13, thereby playing a role in gathering the wind field.

[0063] For example Figure 4 shown, the heat dissipation component is installed at the rear side of the blade 4. The left end of the mounting frame 1 is the first end 11, the right end of the mounting frame 1 is the second end 12, and the number of the heat dissipation plates 2 is six and they are arranged in sequence in the left-right direction. All the heat dissipation plates 2 are arranged parallel to the rotating surface 5, that is, all the heat dissipation plates 2 are perpendicular to the front-back direction. In the direction from the left end of the mounting frame 1 to the center, the distance between the heat dissipation plate 2 and the rotating surface 5 gradually increases, and this distance reaches the maximum value at the third heat dissipation plate 2 counted from the left; in the direction from the right end of the mounting frame 1 to the center, the distance between the heat dissipation plate 2 and the rotating surface 5 gradually decreases.

[0064] As Figure 5 shown, according to another embodiment of the present invention, at the outermost periphery of all the heat dissipation plates 2, the heat dissipation plate 2 adjacent to the first end 11 is the first heat dissipation plate 21, and the heat dissipation plate 2 adjacent to the second end 12 is the second heat dissipation plate 22; the heat dissipation plates 2 located between the first heat dissipation plate 21 and the second heat dissipation plate 22 are the intermediate heat dissipation plates 2.

[0065] The first heat dissipation plate 21 extends in the direction away from the rotating surface 5 and is inclined towards the second end 12, the second heat dissipation plate 22 extends in the direction away from the rotating surface 5 and is inclined towards the first end 11, and at least one intermediate heat dissipation plate 2 is arranged parallel to the rotating surface 5 to form a wind gathering space 13.

[0066] In this embodiment, different from the case where all the heat dissipation plates 2 are inclined or all are parallel, a part of the heat dissipation plates 2 in the heat dissipation assembly are inclined with respect to the rotating surface 5, and another part of the heat dissipation plates 2 are parallel to the rotating surface 5. Specifically, the heat dissipation plates 2 on the left and right sides of the mounting frame 1 are both inclined towards the center of the mounting frame 1, while the heat dissipation plates 2 in the central area of the mounting frame 1 are parallel to the rotating surface 5, and all the heat dissipation plates 2 are arranged in an interleaved manner. In this way, the heat dissipation assembly of this embodiment can also define a relatively large wind-gathering space 13 through the self-inclined structure of some heat dissipation plates 2 and the interleaved distribution structure between all the heat dissipation plates 2, thereby playing a role in gathering the wind field.

[0067] For example Figure 5 As shown, the heat dissipation assembly is installed at the rear side of the blade 4. The left end of the mounting frame 1 is the first end 11, the right end of the mounting frame 1 is the second end 12, and the number of heat dissipation plates 2 is six and they are arranged in sequence in the left-right direction. The two heat dissipation plates 2 on the left side are both inclined to the right, one heat dissipation plate 2 on the right side is inclined to the left, and the three heat dissipation plates 2 in the middle are all parallel to the rotating surface 5.

[0068] In the direction from the left end of the mounting frame 1 to the center, the distance between the heat dissipation plate 2 and the rotating surface 5 gradually increases, and this distance reaches the maximum value at the third heat dissipation plate 2 counted from the left; in the direction from the right end of the mounting frame 1 to the center, the distance between the heat dissipation plate 2 and the rotating surface 5 gradually decreases.

[0069] As Figures 6 to 9 shown, according to an embodiment of the present invention, a wind baffle 6 is connected between every two adjacent heat dissipation plates 2. In this way, the wind baffle 6 can block part of the air flow leaking from the gap, so that the air flow that originally passed through the gap between the two heat dissipation plates 2 can also flow through the heat dissipation plate 2, thereby increasing the air volume passing through the heat dissipation plate 2 and improving the heat dissipation efficiency of the heat dissipation plate 2.

[0070] Furthermore, the wind baffle 6 completely fills the gap between two adjacent heat dissipation plates 2. In this way, the air volume passing through the heat dissipation plate 2 can be further increased, thereby further improving the heat dissipation efficiency of the heat dissipation plate 2.

[0071] As Figure 10 shown, according to an embodiment of the present invention, the heat dissipation plate 2 is rotatably installed on the mounting frame 1. The heat dissipation assembly further includes a driving member 7, and the driving member 7 is in transmission connection with the heat dissipation plate 2.

[0072] In this way, in this embodiment, the angle of the heat dissipation plate 2 is set as an adjustable structure, and drive mechanisms such as mechanical, electric, pneumatic or hydraulic are arranged on each heat dissipation plate 2, such as hydraulic motors, pneumatic motors, electric motors or speed reducers, etc., so that the angle of each heat dissipation plate 2 can be adjusted as needed, thereby making the airflow field more effective in gathering the airflow quality and improving the overall heat dissipation efficiency.

[0073] As Figure 1 shown, the wind turbine according to the embodiment of the second aspect of the present invention includes the heat dissipation component of the wind turbine described in the embodiment of the first aspect of the present invention, and further includes a nacelle 3 and blades 4. The blades 4 are rotatably mounted on the nacelle 3 through a rotating shaft. The heat dissipation component is mounted on the nacelle 3 and is located on the leeward side of the blades 4.
