Description
Technical Field
[0001] This invention relates to the field of heat dissipation technology for wind turbine generators, specifically to a heat dissipation component for a wind turbine generator and a wind turbine generator. Background Technology
[0002] In the global transition of energy structure towards clean and low-carbon energy, wind energy, as a abundant and renewable clean energy source, has seen its development and utilization scale continuously expand. The installed capacity of onshore and offshore wind turbines has been increasing year by year, ushering in a period of rapid development for the wind power equipment manufacturing industry. As the core equipment for converting wind energy into electricity, the operational stability and reliability of wind turbines directly determine the power generation efficiency, operation and maintenance costs, and service life of wind farms. Among these components, the cooling system, as a key supporting component of the wind turbine, bears the important responsibility of controlling the temperature of core heat-generating parts and ensuring the safe operation of the unit under various operating conditions. Its performance has become one of the key factors restricting the development of wind turbines towards high power, large size, and intelligence.
[0003] In actual use, when using water cooling to cool the bushing connection, it is necessary to cool it evenly and keep the coolant flow rate stable. If the coolant is unevenly distributed, the support bearing will have gaps due to temperature differences, resulting in a loose connection with the spindle and shortening its service life. At the same time, unstable flow rate will reduce the heat exchange efficiency of the liquid, resulting in reduced heat dissipation efficiency for the components and affecting the cooling effect. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a heat dissipation component for a wind turbine and a wind turbine, including a support base and a blade assembly. The outer wall of the support base is fixedly connected to the turbine housing, and the outer wall of the support base further includes: The conveying mechanism is fixedly connected to the outer wall of the support base. The conveying mechanism is used to convey coolant. The limiting mechanism is slidably connected to the inner wall of the conveying mechanism at its outer wall, and is used to restrict the coolant to a certain extent. The reinforcing mechanism is fixedly connected to the outer wall of the limiting mechanism, and the reinforcing mechanism is used to improve heat exchange efficiency. A cooling unit is fixedly connected to the outer wall of the support base, a return pipe is fixedly connected to the outer wall of the cooling unit, and a generator set is fixedly connected to the outer wall of the support base.
[0005] When using it, first place the device in the desired location, then inject coolant into the cooling unit, start the cooling unit, and fill all the channels connected to the cooling unit with coolant. Preferably, the conveying mechanism includes: The conveying assembly is fixedly connected to the outer wall of the generator set. A connecting component is fixedly connected to the outer wall of the conveying component.
[0006] Preferably, the limiting mechanism includes: The limiting component is slidably connected to the inner wall of the connecting component; The active component is fixedly connected to the outer wall of the limiting component.
[0007] Preferably, the reinforcing mechanism includes: The reinforcing component is fixedly connected to the outer wall of the movable component; The limiting component is fixedly connected to the outer wall of the movable component.
[0008] Preferably, the conveying assembly includes a main shaft sleeve fixedly connected to the outer wall of the generator set, and a conveying pipe fixedly connected to the outer wall of the cooling unit.
[0009] Preferably, the connecting assembly includes a connecting flange fixedly connected to the outer wall of the main sleeve, a conveying connecting flange fixedly connected to the outer wall of the connecting flange, and a return connecting flange fixedly connected to the outer wall of the connecting flange. In actual use, when cooling the connecting shaft of the air cooler, it is necessary to cool both sides of the shaft evenly. At the same time, the flow rate of the coolant needs to be relatively stable. If the liquid volume increases suddenly, it may cause cavitation. When the bubbles generated by cavitation burst, the heat exchange efficiency will decrease. When the liquid volume drops suddenly, a stagnation zone may be formed, which will prevent heat from being exchanged in time, resulting in a decrease in the cooling efficiency of the components. At this time, when the cooling unit is running, the liquid enters the conveying connection flange through the conveying pipe. The return pipe is fixedly connected to the outer wall of the return connection flange at the end furthest from the cooling unit, and the delivery pipe is fixedly connected to the outer wall of the delivery connection flange at the end furthest from the cooling unit.
[0010] Preferably, the limiting component includes two slots formed on the inner wall of the conveying connection flange, two connecting sliding rods slidably connected to the inner walls of the two slots, and two return springs fixedly connected to the outer walls of the two connecting sliding rods.
[0011] Preferably, the movable component includes a limiting conical ball fixedly connected to the outer wall of the two connecting sliding rods, and a connecting bushing fixedly connected to the outer wall of the main bushing.
[0012] Furthermore, when the liquid contacts the limiting cone, it applies a certain pressure to the limiting cone. Due to the presence of the connecting sliding rod, it is forced to move along the groove towards the connecting flange. The movement of the connecting sliding rod also applies pressure to the return spring, compressing it. When the liquid flow rate remains stable, the pressure applied to the limiting cone also remains stable, keeping the limiting cone at a certain position in the groove. Subsequently, when the liquid supplied by the cooling unit fluctuates, the pressure applied to the limiting cone also fluctuates. As the liquid volume increases, the pressure on the limiting cone increases, causing the limiting cone to move further towards the groove. When the limiting cone ball approaches the connecting flange, the space between the limiting cone ball and the connecting flange decreases, resulting in a reduction in the amount of liquid flowing through. Conversely, when the liquid volume decreases, the limiting cone ball will move away from the connecting flange by a certain position under the action of the return spring, thereby increasing the space between the limiting cone ball and the connecting flange and increasing the amount of liquid flowing through. This helps to maintain a stable amount of liquid entering the connecting flange to a certain extent. At the same time, the connecting component consisting of the connecting sliding rod and the limiting cone ball also divides the flowing liquid into two parts, thus keeping the amount of coolant on both sides relatively uniform. Preferably, the reinforcing component includes a plurality of turbulence connecting blocks fixedly connected to the outer wall of the connecting bushing, and a plurality of limiting plates fixedly connected to the outer wall of the connecting bushing; The limiting component includes several limiting plates fixedly connected to the outer wall of the connecting bushing, and several elastic plates fixedly connected to the outer wall of the connecting bushing.
[0013] A wind turbine includes a blade assembly fixedly connected to the outer wall of the generator set, and a plurality of blades are fixedly connected to the outer wall of the blade assembly.
[0014] In actual operation, as the liquid flows within the space between the connecting flange and the connecting sleeve, laminar flow may occur once the operation stabilizes. This causes the liquid in contact with the connecting sleeve to absorb most of the heat, while the liquid near the inner wall of the connecting flange flows out through the backflow flange before absorbing sufficient heat, resulting in reduced heat exchange efficiency. To address this, a flow interference block, a limiting plate one, and a limiting plate two are installed on the surface of the connecting sleeve. When the liquid enters the space between the connecting sleeve and the connecting flange through the conveying connecting flange, it flows through the isolation channel formed by these three components. When the liquid passes through the limiting plate one... After the channel formed by limiting plate one and limiting plate two, a flow-turbing connecting block is set between limiting plate one and limiting plate two. The flow-turbing connecting block will separate the liquid into two branches. The shape of limiting plate one will cause one branch to block the other branch, thereby breaking the stable flow state of the two branches and disrupting the laminar flow state of the two branches. At the same time, as the liquid continues to move, the shape of limiting plate two will cause the two branches to collide with each other, so that the liquid on the surface of the connecting bushing and the inner wall of the connecting flange will exchange with each other, thereby increasing the absorption of heat by the liquid, improving the heat exchange efficiency, and improving the cooling effect. Utilizing the operating mechanism of the aforementioned mechanism, after the turbulence connecting block diverts the liquid, the two diverted branches collide with each other under the action of the shape of the limiting plate one. This weakens the kinetic energy of the two branches, reducing their kinetic energy and thus reducing the liquid flow velocity. This increases the heat exchange time, allowing the liquid to fully absorb the heat absorbed by the surface of the connecting bushing. Simultaneously, since the turbulence connecting block is connected to the limiting plate one, and the limiting plate two is connected to the connecting bushing, some heat is transferred to the liquid through these three components, further improving the heat exchange efficiency of the liquid and enhancing the cooling effect. After prolonged use, when the blade assembly is subjected to wind force in the same direction, causing it to rotate in the same direction for an extended period, the main bushing will continuously rub against the bushing at the same position. This results in the heat generated on the side connected to the bushing being higher than on the other side. Over time, this can damage internal components and affect their working efficiency. In this case, when one side has higher heat, the temperature on that side will be higher, causing the liquid on that side to expand to a certain extent. This causes the elastic plate to bend slightly towards the other side. After the liquid impacts the elastic plate, its deformation increases, ultimately leading to an increase in the amount of liquid passing through the side with higher heat, thus increasing its cooling effect and enhancing the heat dissipation effect when the heat generation on both sides is different.
[0015] The present invention has the following beneficial effects: (1) In actual use, when cooling the connecting shaft of the fan unit, it is necessary to cool both sides of the shaft. At the same time, the flow rate of the coolant needs to be relatively stable. If the liquid volume increases suddenly, cavitation may occur. When the bubbles generated by cavitation burst, the heat exchange efficiency will decrease. When the liquid volume drops suddenly, a stagnation zone may be formed, which will prevent the heat from being exchanged in time, resulting in a decrease in the cooling efficiency of the components. At this time, when the cooling unit is running, the liquid enters the conveying connecting flange through the conveying pipe. Furthermore, when the liquid contacts the limiting cone ball, it will apply a certain pressure to the limiting cone ball. Due to the presence of the connecting sliding rod, it is forced to move along the groove towards the connecting flange. The movement of the connecting sliding rod will also apply pressure to the return spring, causing it to be compressed. When the liquid flow rate is kept stable, the pressure applied to the limiting cone ball will also be maintained. The system maintains stability, keeping the limiting cone ball at a certain position within the groove. When the cooling unit's delivery liquid fluctuates, the pressure exerted on the limiting cone ball also fluctuates. As the liquid volume increases, the pressure on the limiting cone ball increases, causing it to move closer to the connecting flange. When the limiting cone ball is closer to the connecting flange, the space between it and the flange decreases, resulting in a reduction in the flow of liquid. Conversely, when the liquid volume decreases, the returning spring moves the limiting cone ball away from the flange, increasing the space between it and the flange, thus increasing the flow of liquid. This helps maintain a stable amount of liquid entering the connecting flange to some extent. Simultaneously, the connecting component, consisting of the sliding rod and the limiting cone ball, divides the flowing liquid into two parts, ensuring a relatively uniform flow of coolant on both sides. (2) In actual operation, the liquid flows within the space between the connecting flange and the connecting sleeve. When the operation is stable, laminar flow may occur, causing the liquid in contact with the connecting sleeve to absorb most of the heat. The liquid near the inner wall of the connecting flange will flow out through the backflow connecting flange before absorbing enough heat, resulting in a decrease in its heat exchange efficiency. At this time, several interference flow connecting blocks, limit plate one, and limit plate two are provided on the surface of the connecting sleeve. When the liquid enters the space between the connecting sleeve and the connecting flange through the conveying connecting flange, it will flow through the isolation channel formed by the three. When the liquid passes through the limit plate two, it will flow through the isolation channel formed by the three. After the channel formed by the first positioning plate and the second limiting plate, a flow-turbing connecting block is set between the first and the second limiting plate. The liquid is separated into two branches by the flow-turbing connecting block. The shape of the first limiting plate causes one branch to block the other branch, thereby breaking the stable flow state of the two branches and disrupting the laminar flow state of the two branches. At the same time, as the liquid continues to move, the shape of the second limiting plate causes the two branches to collide with each other, so that the liquid on the surface of the connecting bushing and the inner wall of the connecting flange will exchange with each other, thereby increasing the absorption of heat by the liquid, improving the heat exchange efficiency, and improving the cooling effect. (3) The present invention utilizes the operating mechanism of the above-mentioned mechanism. After the turbulence connecting block divides the liquid, the two branches of the diverted liquid will collide with each other under the action of the shape of the limiting plate one, thereby weakening the liquid kinetic energy of the two branches and reducing their kinetic energy. This reduces the speed of the liquid flow and increases the heat exchange time, allowing the liquid to fully absorb the heat absorbed by the surface of the connecting bushing. At the same time, since the turbulence connecting block is connected to the limiting plate one and the limiting plate two is connected to the connecting bushing, some heat will be transferred to the liquid through the three, further improving the heat exchange efficiency of the liquid and enhancing the cooling effect. (4) After long-term use, when the blade assembly is subjected to wind force in the same direction, it rotates in the same direction for a long time, causing the main bushing to continuously rub against the bushing at the same position. As a result, the heat generated on the side connected to the bushing will be higher than that on the other side. After long-term operation, this will cause damage to the internal components and affect their working efficiency. At this time, when the heat on one side is higher, the temperature on that side will be higher, which will cause the liquid on that side to expand to a certain extent, causing the elastic plate to bend slightly towards the other side. After the liquid impacts the elastic plate, its deformation will increase, which will eventually lead to an increase in the amount of liquid passing through the side with higher heat, thus increasing its cooling effect and enhancing the heat dissipation effect when the heat generation on both sides is different.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1, please refer to Figure 1 - Figure 10 The present invention relates to a heat dissipation assembly for a wind turbine and a wind turbine, comprising a support base 13, a blade assembly 15, and a turbine housing 14 fixedly connected to the outer wall of the support base 13. The outer wall of the support base 13 also includes: The outer wall of the conveying mechanism 1 is fixedly connected to the outer wall of the support base 13. The conveying mechanism 1 is used to convey coolant. The limiting mechanism 2 is slidably connected to the inner wall of the conveying mechanism 1 at its outer wall. The limiting mechanism 2 is used to limit the coolant to a certain extent. The reinforcing mechanism 3 is fixedly connected to the outer wall of the limiting mechanism 2 at its outer wall. The reinforcing mechanism 3 is used to improve heat exchange efficiency. A cooling unit 111 is fixedly connected to the outer wall of the support base 13, a return pipe 112 is fixedly connected to the outer wall of the cooling unit 111, and a generator set 113 is fixedly connected to the outer wall of the support base 13.
[0021] When in use, first place the device in the desired location, then inject coolant into the cooling unit 111, start the cooling unit 111, and fill all the channels connected to the cooling unit 111 with coolant. Conveying mechanism 1 includes: The outer wall of the conveying assembly 11 is fixedly connected to the outer wall of the generator set 113; The connecting component 12 is fixedly connected to the outer wall of the conveying component 11.
[0022] Restricted agency 2 includes: The outer wall of the limiting component 21 is slidably connected to the inner wall of the connecting component 12; The active component 22 is fixedly connected to the outer wall of the limiting component 21.
[0023] Enhancement mechanism 3 includes: The reinforcing component 31 is fixedly connected to the outer wall of the movable component 22. The limiting component 32 is fixedly connected to the outer wall of the movable component 22.
[0024] The conveying assembly 11 includes a main shaft sleeve 114 fixedly connected to the outer wall of the generator set 113, and a conveying pipe 115 fixedly connected to the outer wall of the cooling unit 111.
[0025] The connecting assembly 12 includes a connecting flange 121 fixedly connected to the outer wall of the main shaft sleeve 114, a conveying connecting flange 122 fixedly connected to the outer wall of the connecting flange 121, and a return connecting flange 123 fixedly connected to the outer wall of the connecting flange 121. In actual use, when cooling the connecting shaft of the air cooler unit, it is necessary to cool both sides of the shaft evenly. At the same time, the flow rate of the coolant needs to be relatively stable. If the liquid volume increases suddenly, cavitation may occur. When the bubbles generated by cavitation burst, the heat exchange efficiency will decrease. When the liquid volume drops suddenly, a stagnation zone may be formed, which will prevent heat from being exchanged in time, resulting in a decrease in the cooling efficiency of the components. At this time, when the cooling unit 111 is running, the liquid enters the conveying connection flange 122 through the conveying pipe 115. The outer wall of the return pipe 112 at the end away from the cooling unit 111 is fixedly connected to the outer wall of the return connection flange 123, and the outer wall of the conveying pipe 115 at the end away from the cooling unit 111 is fixedly connected to the outer wall of the conveying connection flange 122.
[0026] The limiting component 21 includes two slots 211 formed in the inner wall of the conveying connection flange 122, two connecting sliding rods 212 slidably connected to the inner wall of the two slots 211, and two return springs 213 fixedly connected to the outer wall of the two connecting sliding rods 212.
[0027] The active component 22 includes a limiting conical ball 221 fixedly connected to the outer wall of the two connecting sliding rods 212, and a connecting bushing 222 fixedly connected to the outer wall of the main bushing 114.
[0028] Furthermore, when the liquid contacts the limiting cone ball 221, it applies a certain pressure to the limiting cone ball 221. Due to the presence of the connecting sliding rod 212, it is forced to move along the slot 211 towards the connecting flange 121. The movement of the connecting sliding rod 212 also applies pressure to the return spring 213, compressing it. When the liquid flow rate remains stable, the pressure applied to the limiting cone ball 221 also remains stable, keeping the position of the limiting cone ball 221 at a certain position in the slot 211. Subsequently, when the liquid supplied by the cooling unit 111 fluctuates, the pressure applied by the liquid to the limiting cone ball 221 also fluctuates. When the liquid volume increases, the pressure on the limiting cone ball 221 increases, causing the limiting cone ball 221 to move further... When the limiting conical ball 221 approaches the connecting flange 121, the space between the limiting conical ball 221 and the conveying connecting flange 122 decreases, resulting in a reduction in the amount of liquid flowing through. Conversely, when the amount of liquid decreases, under the action of the return spring 213, the limiting conical ball 221 will move away from the connecting flange 121 by a certain position, thereby increasing the space between the limiting conical ball 221 and the conveying connecting flange 122, resulting in an increase in the amount of liquid flowing through, thus maintaining a certain stability in the amount of liquid entering the connecting flange 121 to a certain extent. At the same time, the connecting component composed of the connecting sliding rod 212 and the limiting conical ball 221 will also divide the flowing liquid into two parts, thereby keeping the amount of coolant on both sides relatively uniform. The reinforcing component 31 includes several turbulence connecting blocks 311 fixedly connected to the outer wall of the connecting bushing 222, and several limiting plates 312 fixedly connected to the outer wall of the connecting bushing 222. The limiting component 32 includes several limiting plates 321 fixedly connected to the outer wall of the connecting bushing 222, and several elastic plates 322 fixedly connected to the outer wall of the connecting bushing 222.
[0029] A wind turbine includes a blade assembly 15 fixedly connected to the outer wall of a generator set 113, and a plurality of blades 16 are fixedly connected to the outer wall of the blade assembly 15.
[0030] In actual operation, as the liquid flows within the space between the connecting flange 121 and the connecting sleeve 222, laminar flow may occur once the operation stabilizes. This causes the liquid in contact with the connecting sleeve 222 to absorb most of the heat, while the liquid near the inner wall of the connecting flange 121 flows out through the backflow connecting flange 123 before absorbing sufficient heat, resulting in reduced heat exchange efficiency. Therefore, several interference flow connecting blocks 311, limit plate one 312, and limit plate two 321 are provided on the surface of the connecting sleeve 222. When the liquid enters the space between the connecting sleeve 222 and the connecting flange 121 through the conveying connecting flange 122, it flows through the isolation channel formed by these three blocks. When the liquid passes through the limit... After the channel formed by the first plate 312 and the second limiting plate 321, a flow-turbing connecting block 311 is set between the first limiting plate 312 and the second limiting plate 321. The liquid will be separated into two branches by the flow-turbing connecting block 311. The shape of the first limiting plate 312 will cause one branch to block the other branch, thereby breaking the stable flow state of the two branches and disrupting the laminar flow state of the two branches. At the same time, as the liquid continues to move, the shape of the second limiting plate 321 will cause the two branches to collide with each other, so that the liquid on the surface of the connecting sleeve 222 and the inner wall of the connecting flange 121 will exchange with each other, thereby increasing the absorption of heat by the liquid, improving the heat exchange efficiency, and improving the cooling effect. Utilizing the operating mechanism of the aforementioned mechanism, after the turbulence connecting block 311 diverts the liquid, the two diverted branches collide with each other under the action of the shape of the limiting plate 312, thereby weakening the liquid kinetic energy of the two branches and reducing their kinetic energy. This reduces the speed of the liquid flow, increases the heat exchange time, and allows the liquid to fully absorb the heat absorbed by the surface of the connecting sleeve 222. At the same time, since the turbulence connecting block 311 is connected to the limiting plate 312 and the limiting plate 321 is connected to the connecting sleeve 222, some heat is transferred to the liquid through the three, further improving the heat exchange efficiency of the liquid and enhancing the cooling effect. After prolonged use, when the blade assembly 15 is subjected to wind force in the same direction, causing it to rotate in the same direction for an extended period, the main shaft sleeve 114 will continuously rub against the shaft sleeve at the same position. This results in the heat generated on the side connected to the shaft sleeve 222 being higher than that on the other side. After prolonged operation, this can damage internal components and affect their working efficiency. At this time, when the heat on one side is higher, the temperature on that side will be higher, causing the liquid on that side to expand to a certain extent. This causes the elastic plate 322 to bend slightly towards the other side. After the liquid impacts the elastic plate 322, its deformation will increase, ultimately leading to an increase in the amount of liquid passing through the side with higher heat, which increases its cooling effect and enhances the heat dissipation effect when the heat generation on both sides is different.
[0031] One specific application of this embodiment is as follows: When in use, first place the device in the desired suitable position, then inject coolant into the cooling unit 111, start the cooling unit 111, so that the cooling unit 111 fills all the channels it is connected to with coolant. In practical use, when cooling the connecting shaft of the fan unit, it is necessary to uniformly cool both sides of the shaft and maintain a relatively stable coolant flow rate. A sudden increase in liquid volume may cause cavitation, which reduces heat exchange efficiency when the bubbles burst. Conversely, a sudden decrease in liquid volume may create stagnation zones, preventing timely heat exchange and further reducing cooling efficiency. When the cooling unit 111 is running, liquid enters the connecting flange 122 through the delivery pipe 115. Upon contact with the limiting cone ball 221, the liquid applies pressure. Due to the presence of the connecting sliding rod 212, it is forced to move along the slot 211 towards the connecting flange 121. This movement of the connecting sliding rod 212 also applies pressure to the return spring 213, compressing it. Once the liquid flow rate stabilizes, the pressure on the limiting cone ball 221 also remains stable, ensuring the position of the limiting cone ball 221 remains stable. The limiting cone ball 221 is maintained at a certain position in the slot 211. When the liquid being transported by the cooling unit 111 fluctuates, the pressure exerted by the liquid on the limiting cone ball 221 also fluctuates. When the liquid volume increases, the pressure on the limiting cone ball 221 increases, causing the limiting cone ball 221 to move closer to the connecting flange 121. When the limiting cone ball 221 moves closer to the connecting flange 121, the space between the limiting cone ball 221 and the conveying connecting flange 122 decreases, resulting in a decrease in the amount of liquid flowing through. Conversely, when the liquid volume decreases, under the action of the return spring 213, the limiting cone ball 221 moves away from the connecting flange 121 by a certain position, thereby increasing the space between the limiting cone ball 221 and the conveying connecting flange 122, resulting in an increase in the amount of liquid flowing through. This, to a certain extent, maintains the stability of the amount of liquid entering the connecting flange 121. At the same time, the connecting member consisting of the connecting sliding rod 212 and the limiting cone ball 221 also divides the flowing liquid into two parts, thereby keeping the amount of coolant on both sides relatively uniform. In actual operation, as the liquid flows within the space between the connecting flange 121 and the connecting sleeve 222, laminar flow may occur once the operation stabilizes. This causes the liquid in contact with the connecting sleeve 222 to absorb most of the heat, while the liquid near the inner wall of the connecting flange 121 flows out through the backflow connecting flange 123 before absorbing sufficient heat, resulting in reduced heat exchange efficiency. Therefore, several interference flow connecting blocks 311, limit plate one 312, and limit plate two 321 are provided on the surface of the connecting sleeve 222. When the liquid enters the space between the connecting sleeve 222 and the connecting flange 121 through the conveying connecting flange 122, it flows through the isolation channel formed by these three blocks. When the liquid passes through the limit... After the channel formed by the first plate 312 and the second limiting plate 321, a flow-turbing connecting block 311 is set between the first limiting plate 312 and the second limiting plate 321. The liquid will be separated into two branches by the flow-turbing connecting block 311. The shape of the first limiting plate 312 will cause one branch to block the other branch, thereby breaking the stable flow state of the two branches and disrupting the laminar flow state of the two branches. At the same time, as the liquid continues to move, the shape of the second limiting plate 321 will cause the two branches to collide with each other, so that the liquid on the surface of the connecting sleeve 222 and the inner wall of the connecting flange 121 will exchange with each other, thereby increasing the absorption of heat by the liquid, improving the heat exchange efficiency, and improving the cooling effect. Utilizing the operating mechanism of the aforementioned mechanism, after the turbulence connecting block 311 diverts the liquid, the two diverted branches collide with each other under the action of the shape of the limiting plate 312, thereby weakening the liquid kinetic energy of the two branches and reducing their kinetic energy. This reduces the speed of the liquid flow, increases the heat exchange time, and allows the liquid to fully absorb the heat absorbed by the surface of the connecting sleeve 222. At the same time, since the turbulence connecting block 311 is connected to the limiting plate 312 and the limiting plate 321 is connected to the connecting sleeve 222, some heat is transferred to the liquid through the three, further improving the heat exchange efficiency of the liquid and enhancing the cooling effect. After prolonged use, when the blade assembly 15 is subjected to wind force in the same direction, causing it to rotate in the same direction for an extended period, the main shaft sleeve 114 will continuously rub against the shaft sleeve at the same position. This results in the heat generated on the side connected to the shaft sleeve 222 being higher than that on the other side. After prolonged operation, this can damage internal components and affect their working efficiency. At this time, when the heat on one side is higher, the temperature on that side will be higher, causing the liquid on that side to expand to a certain extent. This causes the elastic plate 322 to bend slightly towards the other side. After the liquid impacts the elastic plate 322, its deformation will increase, ultimately leading to an increase in the amount of liquid passing through the side with higher heat, which increases its cooling effect and enhances the heat dissipation effect when the heat generation on both sides is different.
