[0002] When the converter in a wind turbine generator is running, it is prone to overheating. At this time, heat dissipation is required. Generally, a fan is used for subsequent heat dissipation to enable the equipment to operate stably.

[0003] After retrieval, a Chinese patent discloses a heat dissipation device for the rated power test of a traction converter (publication number: CN204014391 U). This patented technology uses multiple fans with relatively low power, solves the problem of insufficient air volume of a single fan, enables the start of the fan to be completed without a frequency converter, and greatly saves costs. However, in the technical solution of the above patent document, when multiple fans jointly output wind power, there are prone to gaps in the connection, resulting in leakage of wind power during output and affecting the wind power output effect.

[0004] Therefore, an intelligent heat dissipation device for a full-power converter of a fan is proposed to solve the above problems. Summary of the Utility Model

[0006] The utility model realizes the above purpose through the following technical solutions.

[0011] Preferably, the width of the side end of the limiting sliding seat that fits the air guide frame is smaller than the other end that is parallel to each other.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] During specific implementation: As Figures 1 - 4As shown in the figure, an intelligent heat dissipation device for a full-power converter of a fan includes: a bottom plate 3, an installation frame 1 and a temperature measurement device 7 are fixedly connected to the upper end of the bottom plate 3, two heat dissipation fans 2 are fixedly connected to the upper end of the bottom plate 3, a wind guide frame 4 is arranged on the upper side of the installation frame 1, and the two heat dissipation fans 2 output outward through the wind guide frame 4; a connection mechanism 5, a connection mechanism 5 for stably connecting the two heat dissipation fans 2 to the wind guide frame 4 is arranged on one side of the wind guide frame 4; a sealing component 6, a sealing component 6 for sealing the connection of the wind guide frame 4 is arranged on one side of the wind guide frame 4; wherein, two groups of connection mechanisms 5 are provided, each group of connection mechanisms 5 includes a fixing component 501 arranged on one side of the wind guide frame 4, and a stabilizing component 502 is arranged on one side of the fixing component 501. When the device outputs wind for heat dissipation, the heat dissipation fans 2 are started to output wind at this time. Since the wind is likely to leak at the connection of the two heat dissipation fans 2, the wind guide frame 4 and the heat dissipation fans 2 are stably connected by the fixing component 501 to prevent disconnection. The fixing component 501 is not easily skewed when connected by the stabilizing component 502. The connection between the wind guide frame 4 and the bottom plate 3 and the heat dissipation fans 2 is sealed by the sealing component 6 to prevent air leakage, so that the device stably outputs wind and the output effect is better. For those skilled in the art, the heat dissipation fans 2 are prior art and will not be elaborated here. The temperature measurement device 7 includes a temperature measurement sensor and a PLC controller, which can conveniently detect the temperature of the converter, and conveniently control the number of heat dissipation fans 2 turned on according to the equipment temperature, for intelligent control, saving energy and ensuring the heat dissipation effect at the same time.

[0023] As Figure 3 and Figure 4As shown, a hollow rotating shaft 5014 is rotatably connected to the side end of the air guide frame 4. A gear 5013 is fixedly connected to the surface of the hollow rotating shaft 5014. The gear 5013 is meshed with the adjacent ends of two racks 5012. The fixing assembly 501 includes a mounting seat 5011 fixedly connected to the side end of the heat dissipation fan 2. Two mutually parallel racks 5012 are slidably connected to the side end of the air guide frame 4. Clamping rods 5017 are fixedly connected to the upper ends of the two racks 5012. The two clamping rods 5017 are both slidably connected to the inner wall of the mounting seat 5011. When connecting the air guide frame 4 and the heat dissipation fan 2, at this time, the air guide frame 4 is sleeved on the surface of the air outlet end of the heat dissipation fan 2, and the clamping rod 5017 is slid to the inner wall of the mounting seat 5011 for fixing. When unlocking is required, at this time, the hollow rotating shaft 5014 is rotated. The hollow rotating shaft 5014 drives the gear 5013 to rotate. The gear 5013 drives the two racks 5012 to move away from each other. At this time, the fixing assembly 501 is unlocked, and the air guide frame 4 can be conveniently disassembled. A spring 5016 is fixedly connected to the inner wall of the gear 5013. A fixing shaft 5015 is fixedly connected to the side end of the air guide frame 4. One end of the spring 5016 is fixedly connected to the fixing shaft 5015. The spring 5016 is sleeved on the circumferential surface of the fixing shaft 5015. When the fixing assembly 501 is fixed, the hollow rotating shaft 5014 is prone to reverse rotation, causing the fixing to become loose. At this time, the hollow rotating shaft 5014 is continuously pulled by the spring 5016 to be in a locked state, making the hollow rotating shaft 5014 not prone to reverse rotation and becoming loose, and being more stable. The stabilizing assembly 502 includes two limiting sliding seats 5021 fixedly connected to the side end of the air guide frame 4. Limiting sliding grooves 5022 are provided on the side ends of the two racks 5012. The limiting sliding seats 5021 are slidably matched with the limiting sliding grooves 5022. When the rack 5012 slides to drive the clamping rod 5017 to move for fixing, at this time, the rack 5012 is prone to skew. Through the sliding fit of the limiting sliding seat 5021 and the limiting sliding groove 5022, when the rack 5012 slides, it is not prone to skew and is more stable. The width of the side end of the limiting sliding seat 5021 that fits the air guide frame 4 is smaller than the other end that is mutually parallel. The cross section of the limiting sliding seat 5021 is an isosceles trapezoid. Through the shape of the limiting sliding seat 5021, when the rack 5012 slides and is not prone to skew, it can stably fit and slide on the air guide frame 4.

[0024] As Figure 2As shown, the sealing assembly 6 includes a second connecting seat 603 fixedly connected to the upper end of the bottom plate 3. A second sealing ring 604 is fixedly connected to the inner wall of the second connecting seat 603. The air guiding frame 4 is in interference fit with the second sealing ring 604. A first connecting seat 601 is fixedly connected to the upper end of the air guiding frame 4. A first sealing ring 602 is fixedly connected to the inner wall of the first connecting seat 601. The first sealing ring 602 is in interference fit with the surface of the heat dissipation fan 2. The connection between the air guiding frame 4 and the heat dissipation fan 2 and the bottom plate 3 can be sealed through the second sealing ring 604 and the first sealing ring 602. The second connecting seat 603 and the first connecting seat 601 support the installation of the air guiding frame 4, so that the sealing performance is increased when the air guiding frame 4 is connected, and the air output effect of the heat dissipation fan 2 is increased.

[0025] When the present utility model is in use, when the device outputs wind for heat dissipation, the heat dissipation fan 2 is started to output wind at this time. Since the wind is likely to leak at the connection of the two heat dissipation fans 2, at this time, the air guiding frame 4 is sleeved on the air outlet of the heat dissipation fan 2, and the lower side abuts against the air exhaust part of the bottom plate 3. After the installation and placement are completed, the spring 5016 drives the hollow rotating shaft 5014 and the gear 5013 to rotate. The gear 5013 drives the two racks 5012 to approach each other, and the clamping rod 5017 is slid to the inner wall of the mounting seat 5011 for fixation. At this time, the first sealing ring 602 and the second sealing ring 604 seal the connection of the air guiding frame 4, reduce the leakage of the output air, so that the internal air can be better output to the heat dissipation position, and the heat dissipation effect is increased.

[0026] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only includes an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
