Description
Technical Field
[0001] This utility model relates to the technical field of wind power capacitor housings, and in particular to a highly sealed and moisture-proof wind power capacitor housing. Background Technology
[0002] The wind power capacitor casing refers to the outer shell used to encapsulate capacitors in wind power equipment, and is usually made of aluminum or other metal materials.
[0003] This type of casing plays a crucial role in wind power systems, with its main functions including: protecting internal components: the casing acts as an external protective layer to prevent the components inside the capacitor from being affected by the external environment, such as dust and moisture.
[0004] In the existing technology, the casing of most power generation capacitors is made of aluminum, which has insufficient thermal conductivity and a high coefficient of thermal expansion. The internal heat accumulation leads to excessively high capacitor temperature, causing the casing to bulge or even the dielectric to crack, thus affecting the sealing performance. On the other hand, after the bulging and decay, the moisture-proof effect is easily reduced. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a highly sealed and moisture-proof wind power generation capacitor shell, so as to solve the technical problems mentioned in the background art.

A connector is installed between the two cold air pipes to connect the cold air pipes to the protective shell. An exhaust pipe is installed at one end of the vortex tube. A compressed air pump is installed on one side of the air intake ring.
[0010] Furthermore, the vortex tube includes:
[0011] The transverse tube has several evenly distributed arc-shaped grooves on its outer peripheral wall, which connect the inner cavity of the transverse tube with the inner cavity of the intake ring.
[0012] A positioning plate is fixedly connected to the side wall of the horizontal tube. The positioning plate has a threaded hole inside for installing the air conditioning pipe, and the threaded hole is coaxial with the horizontal tube.
[0013] Furthermore, the discharge pipe is fixedly connected to the transverse pipe via a flange, and a shielding component is provided inside the end of the discharge pipe away from the transverse pipe.
[0014] Furthermore, the shielding component includes an annular plate that is fixedly connected to the discharge pipe by bolts. A plug is fixedly connected to the center of the annular plate by several connecting rods. The plug is inserted into the interior of the discharge pipe, and there is a gap between the outer peripheral wall of the plug and the inner wall of the discharge pipe.
[0015] Furthermore, one end of the air cooling pipe inserted inside the transverse pipe extends into the interior of the exhaust pipe, and a guide ring is provided inside the air cooling pipe.
[0016] Furthermore, the connector includes a three-way pipe, with its two ends connected to two cooling pipes respectively. The outlet end of the three-way pipe is connected to the protective shell through a pipe, and a guide fan is installed inside the three-way pipe.
[0017] Furthermore, a lead wire is provided at the tail end of the capacitor protection housing, and a sealing ring is provided at the connection between the lead wire and the capacitor protection housing.
[0018] In summary, this utility model has at least one of the following beneficial technical effects:
[0019] 1. This high-sealing, moisture-proof wind power generation capacitor casing, after compressed air enters the air intake ring, forms an air vortex in the vortex tube. Due to the rapid expansion and rotation of the air, the air forms a hot air zone and a cold air zone. The cold air is discharged into the interior of the protective casing through the cold air pipe and discharged along the protective casing, so that the cold air can fully contact the outer wall of the capacitor protective casing to achieve the purpose of rapid cooling. This prevents the capacitor protective casing from deforming due to heat accumulation, which would lead to a decrease in sealing performance, thereby achieving the purpose of protecting the internal capacitor.
[0020] 2. In this high-sealing, moisture-proof wind power generation capacitor casing, when the cold air is pushed into the interior of the three-way pipe by the cold air pipes on both sides, the guide vortex fan inside the three-way pipe rotates, causing the guide vortex fan to rotate, thereby achieving the purpose of pushing and guiding the cold air, improving the flow of the cold air, and achieving the purpose of improving the cooling effect.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] Example:
[0030] Reference Figures 1-5 The present invention discloses a highly sealed and moisture-proof wind power generation capacitor housing, comprising:
[0031] The substrate 1 has a protective shell 2 mounted on its top. Inside the protective shell 2, there is a capacitor protection shell 3. The capacitor protection shell 3 is enclosed, and a through wire 4 is provided at the tail end of the capacitor protection shell 3. A sealing ring is provided at the connection between the through wire 4 and the capacitor protection shell 3. The through wire 4 is used to connect the capacitor inside the capacitor protection shell 3 to the components inside the wind turbine.
[0032] An air intake ring 5 is mounted on one side of the top of the substrate 1. A vortex tube 6 is arranged inside the air intake ring 5. A cold air tube 7 is arranged at the center of the vortex tube 6. A connector 8 is arranged between the two cold air tubes 7 to connect the cold air tubes 7 and the protective shell 2. A discharge pipe 9 is arranged at one end of the vortex tube 6. A compressed air pump is arranged on one side of the air intake ring 5.
[0033] In this embodiment, since the heat dissipation of capacitors with aluminum casings in the prior art is mostly achieved through direct heat dissipation from the aluminum casing, it is easy to have insufficient thermal conductivity, resulting in heat accumulation and causing the aluminum casing to bulge and crack. To change this situation, the following technical solution is proposed in this embodiment:
[0034] Specifically, during use, the compressed air pump compresses outside air and pushes it into the interior of the intake ring 5. After entering the intake ring 5, the compressed air enters the vortex tube 6, forming an air vortex through the vortex tube 6 and expanding rapidly. Due to the rapid expansion and rotation of the air, a vortex is formed inside the vortex tube 6. The high-speed rotating outer gas generates heat due to friction, forming a high-temperature zone, while the low-speed central gas absorbs heat due to expansion, forming a low-temperature zone. It continues to flow towards one end of the discharge pipe 9. After contacting the shield 10 set at one end of the discharge pipe 9, it is blocked by the shield 10, causing the cold air to be deflected. At this time, the cold air is discharged through the cold air pipe 7 and enters the interior of the protective shell 2 through the connector 8, and is discharged along the protective shell 2. At this time, the cold air can evenly contact the outer wall of the capacitor protective shell 3 under the influence of the protective shell 2, achieving the purpose of rapid cooling, thereby preventing the capacitor protective shell 2 from deforming due to heat accumulation, which would lead to a decrease in sealing performance, and thus achieving the purpose of protecting the internal capacitor.
[0035] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the vortex tube 6 includes:
[0036] The transverse tube 61 has several evenly distributed arc-shaped grooves 62 on its outer peripheral wall, which connect the inner cavity of the transverse tube 61 with the inner cavity of the intake ring 5.
[0037] A positioning plate 63 is fixedly connected to the side wall of the horizontal tube 61. The positioning plate 63 has a threaded hole inside for installing the air conditioning pipe 7, and the threaded hole is coaxial with the horizontal tube 61.
[0038] In this embodiment, by setting the arc groove 62, when compressed air enters the interior of the intake ring 5, the air enters the interior of the transverse tube through the guide of the arc groove 62, and forms a vortex through the guide of the arc groove 62, thereby enabling the air to rotate at high speed inside the transverse tube 61, so as to achieve the purpose of air stratification to form cold air and hot air.
[0039] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the discharge pipe 9 is fixedly connected to the transverse pipe 61 via a flange, and a shielding member 10 is provided inside the end of the discharge pipe 9 away from the transverse pipe 61.
[0040] In this embodiment, the cone-shaped baffle 10 ensures that when the rotating airflow reaches the position, the low-temperature gas in the central region, due to its low kinetic energy, collides with the baffle and flows in the opposite direction, exiting from the cold air outlet near the air inlet.
[0041] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the shielding member 10 includes an annular plate 101 that is fixedly connected to the discharge pipe 9 by bolts. A plug 102 is fixedly connected to the center of the annular plate 101 by several connecting rods. The plug 102 is inserted into the interior of the discharge pipe 9, and there is a gap between the outer peripheral wall of the plug 102 and the inner wall of the discharge pipe 9.
[0042] In this embodiment, when the rotating airflow comes into contact with the plug 102, the high-temperature air pressure in the outer ring is greater than that in the central cold air zone, and the kinetic energy of the cold air zone is lower. Therefore, the cold air zone will quickly turn back after contacting the plug 102, while the high-pressure hot air will be discharged through the inclined surface of the plug 102 and the gap between the plug 102 and the inner wall of the discharge pipe 9, thereby achieving the purpose of separating the cold air and the hot air.
[0043] In a further preferred embodiment of this utility model, such as Figure 4 As shown, one end of the air cooling pipe 7 inserted inside the horizontal pipe 61 extends into the interior of the discharge pipe 9, and a guide ring 11 is provided inside the air cooling pipe 7.
[0044] In this embodiment, the guide ring 11 is designed to guide the compressed air after it enters the interior of the horizontal tube, so that the rotating air moves toward the discharge pipe 9 and avoids the formation of turbulent airflow.
[0045] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the connector 8 includes a three-way pipe 81, with both ends of the three-way pipe 81 connected to two air cooling pipes 7 respectively. The air outlet of the three-way pipe 81 is connected to the protective shell 2 through a pipe. A guide fan 82 is installed inside the three-way pipe 81.
[0046] In this embodiment, when the cold air is pushed into the interior of the three-way pipe 81 by the cold air pipes 7 on both sides, the guide fan 82 inside the three-way pipe 81 rotates, so that the guide fan 82 rotates, thereby achieving the purpose of pushing and guiding the cold air, improving the flow of the cold air, and achieving the purpose of improving the cooling effect.
[0047] The implementation principle of the above embodiment is as follows: The compressed air pump compresses the outside air and pushes it into the interior of the intake ring 5. After entering the intake ring 5, the compressed air enters the vortex tube 6. The vortex tube 6 forms an air vortex and expands rapidly. Due to the rapid expansion and rotation of the air, a vortex is formed inside the vortex tube 6. The high-speed rotating outer gas generates heat due to friction, forming a high-temperature zone, while the low-speed gas in the center absorbs heat due to expansion, forming a low-temperature zone. It continues to flow towards one end of the discharge pipe 9. After contacting the shield 10 set at one end of the discharge pipe 9, it is blocked by the shield 10, causing the cold air to be deflected. At this time, the cold air is discharged through the cold air pipe 7 and enters the interior of the protective shell 2 through the connector 8, and is discharged along the protective shell 2. At this time, the cold air can evenly contact the outer wall of the capacitor protective shell 3 under the influence of the protective shell 2, achieving the purpose of rapid cooling, thereby preventing the capacitor protective shell 2 from deforming due to heat accumulation, which would lead to a decrease in sealing performance, and thus achieving the purpose of protecting the internal capacitor.
[0048] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
