[0001] This invention relates to the field of heat dissipation equipment technology, and in particular to a high-efficiency heat dissipation wind turbine nacelle. Background Technology

[0002] The nacelle is the core "brain" and "body" of a wind turbine generator set. Located at the top of the tower, it integrates key equipment such as the transmission system (including the main shaft and gearbox for speed transmission), generator (converting mechanical energy into electrical energy), yaw system (driving the nacelle to align with the wind direction), braking system (ensuring safe shutdown), and control and monitoring systems (monitoring the operating status in real time). Externally, it is equipped with a deflector to optimize airflow, and a meteorological station is installed on top to collect environmental data. A high-efficiency heat dissipation wind turbine nacelle refers to a type of wind turbine nacelle with excellent heat dissipation.

[0003] Currently, traditional engine compartment cooling methods mostly use cooling fans installed on the top or side to cool the engine by natural wind or forced airflow. However, the complex airflow path can easily create vortices or blind spots inside the engine compartment, leading to excessive local temperature rise. In addition, with long-term operation, the cooling vents can become clogged with dust, which in turn affects the cooling effect. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the gas flow path is complex and it is easy to form vortices or blind spots inside the cabin, resulting in excessive local temperature rise; in addition, with long-term operation, the heat dissipation holes will be blocked by dust, thus affecting the heat dissipation effect.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0029] Reference Figures 1-10 This embodiment provides a high-efficiency heat dissipation wind turbine nacelle, including a support part 1, on which a heat dissipation part 2 is disposed, a cleaning part 3 is disposed on the heat dissipation part 2, and an adjustment part 4 disposed on the support part 1; the cleaning part 3 is composed of a drive component 31, a control component 32 and a cleaning component 33; the drive component 31 and the control component 32 are connected to control its up-and-down reciprocating motion; the control component 32 is used to connect the cleaning component 33 and transfer the kinetic energy provided by the drive component 31 to the cleaning component 33; the cleaning component 33 is used to clean the heat dissipation part 21 and prevent dust from clogging the air inlet.

[0030] The support unit 1 is provided as a working place for the entire heat dissipation mechanism. The heat dissipation unit 2 is located inside the support unit 1 and is used to cool the air entering the support unit 1. The cleaning unit 3 is located inside the heat dissipation unit 2 and is used to clean the air inlet 12 on the heat dissipation unit 2 when the heat dissipation unit 2 is in operation, so as to prevent dust from clogging the air inlet 12 of the heat dissipation unit 2 and affecting the heat dissipation effect.

[0031] Furthermore, the cleaning unit 3 consists of three parts: a drive component 31, a control component 32, and a cleaning component 33. The drive component 31 drives the control component 32, causing the internal parts of the control component 32 to reciprocate. The control component 32 connects the cleaning component 33 and the drive component 31, causing the cleaning component 33 to reciprocate up and down as the control component 32 reciprocates. During the reciprocating motion of the cleaning component 33, it scrapes the air inlet 12 on the heat dissipation unit 2. This removes dust adhering to the air inlet 12, increasing the speed at which natural air enters the heat dissipation unit 2 and preventing poor heat dissipation.

[0032] In summary: After the drive component 31 is activated, it drives the control component 32 to operate, causing the internal parts of the control component 32 to reciprocate. The control component 32, acting as a connecting hub, drives the cleaning component 33 to reciprocate up and down simultaneously during its vertical movement. When the cleaning component 33 moves, it scrapes and cleans the air inlet 12 of the heat dissipation unit 2, effectively removing attached dust and accelerating the entry of natural air into the heat dissipation unit 2, preventing dust from clogging the air inlet 12 and affecting the heat dissipation effect. Furthermore, the electric push rod 421 can control the operation of the adjusting component 42, causing the baffle 411 to rotate, closing the air passages on both sides and guiding natural air to concentrate into the heat dissipation module, further improving heat dissipation efficiency.

[0033] Reference Figures 1-8 As an optional embodiment, a high-efficiency heat dissipation wind turbine nacelle is provided, including a drive component 31 including a protective frame 311, a drive motor 312 disposed inside the protective frame 311, a rotating rod 313 disposed at the output end of the drive motor 312, and a long rod 314 disposed on the rotating rod 313.

[0034] The drive motor 312 is fixedly connected inside the protective frame 311, and its output end passes through the protective frame 311. A rotating rod 313 is fixedly connected to the output end of the drive motor 312. When the drive motor 312 is operating, it drives the rotating rod 313 to rotate. A long rod 314 is rotatably connected to the other end of the rotating rod 313. When the rotating rod 313 moves, it drives the long rod 314 to move.

[0035] Furthermore, the control component 32 includes a swing arm 321 disposed on the long rod 314, a rotating bearing 322 disposed in the middle of the swing arm 321, a dustproof plate 323 disposed on the bearing, and a control groove 324 disposed on the swing arm 321.

[0036] The rotating bearing 322 is fixedly connected to the center of the dustproof rod. A swing rod 321 is connected to the outer wall of the rotating bearing 322, with the bearing positioned at the center of the swing rod 321. The other end of the long rod 314 is connected to a position slightly above the center of the swing rod 321. Control slots 324 are formed at both the upper and lower ends of the swing rod 321.

[0037] Preferably, by controlling the operation of the drive motor 312, the rotating rod 313 rotates along with it. When the rotating rod 313 rotates, it drives the long rod 314 to move. This causes the long rod 314 to pull the swing rod 321 to perform a pendulum-like motion.

[0038] Furthermore, the cleaning component 33 includes a long groove 331 disposed on the dustproof plate 323, a moving block 332 disposed inside the long groove 331, scrapers 333 disposed at both ends of the moving block 332, a brush 334 disposed inside the scraper 333, and a connecting rod 335 disposed on the scraper 333.

[0039] The elongated grooves 331 are provided in two sets, with two grooves in each set, located at the top and bottom ends and the middle part of the dustproof plate 323, respectively. Movable blocks 332 are disposed inside the elongated grooves 331, and scrapers 333 are fixedly connected to both ends of the movable blocks 332. A groove 431 is formed inside the scraper 333, and a brush 334 is disposed inside the groove 431. A connecting rod 335 is provided at the front end of each scraper 333, and the outer wall of the connecting rod 335 is disposed inside the control groove 324.

[0040] Preferably, when the swing arm 321 performs a pendulum-like motion, it drives the scraper 333 to reciprocate up and down via the connecting rod 335, causing the scraper 333 to remove dust adhering to the dustproof plate 323. Simultaneously, the internal brush 334 cleans the dust inside the through holes on the dustproof plate 323, preventing dust from clogging the air inlet 12 of the heat dissipation unit 2.

[0041] Furthermore, the heat dissipation unit 2 includes a heat dissipation component 21, which includes a housing 211 disposed on the protective frame 311, a partition 212 disposed inside the housing 211, and a plurality of fans 213 disposed on the partition 212.

[0042] The outer casing 211 is designed to enclose the entire heat dissipation unit 2, preventing poor heat dissipation due to external factors. Two partitions 212 are located inside the outer casing 211. One partition 212 is located at one end of the outer casing 211, and the other partition 212 is located at the rear of the cleaning unit 3. Multiple fans 213 are fixedly connected to the internal partitions 212. The fans 213 are used to accelerate airflow inside the outer casing 211, increasing heat dissipation.

[0043] Preferably, the operation of the fan 213 accelerates the airflow inside the casing 211, thereby increasing the airflow speed into the engine compartment and thus enhancing the heat dissipation effect.

[0044] Furthermore, the heat dissipation unit 2 also includes a cooling component 22, which includes a water tank 221 disposed inside the housing 211, a pump 222 disposed inside the water tank 221, a condenser 223 disposed on the pump 222, a conduit 224 disposed on the condenser 223, and a heat sink 225 disposed on the conduit 224.

[0045] The water tank 221 is fixedly connected inside the outer casing 211. A pump 222 is fixedly connected inside the water tank 221, supplying coolant to the condenser 223. The condenser 223 is located outside the water tank 221 and receives the coolant supplied by the pump 222, cooling it. Multiple conduits 224 are installed on the condenser 223 to return the coolant supplied by the pump 222 back to the water tank 221, forming an internal circulation. Multiple heat sinks 225 are installed on the conduits 224. While the condenser 223 cools the internal coolant, the heat sinks 225 draw out cold air, thus cooling the air passing through the outer casing 211, lowering the air temperature, and enhancing the heat dissipation effect.

[0046] Preferably, the coolant inside the condenser is pumped by pump 222 to the condenser 223 for cooling, and then flows back to the water tank 221 through conduit 224. When the coolant is transported to the conduit 224, the heat sink 225 on the outside will draw out the cold air, thereby cooling the air and making the heat dissipation effect better.

[0047] In summary: After the equipment is started, the heat dissipation system and the cleaning system operate synchronously. The drive motor 312 starts to operate, driving the rotating rod 313 to rotate. The rotating rod 313 pulls the swing rod 321 to perform a pendulum motion through the long rod 314. The swing rod 321 drives the scraper 333 set in the long groove 331 of the dustproof plate 323 to move up and down reciprocally through the connecting rod 335. The brush 334 on the scraper 333 cleans the dust in the through holes of the dustproof plate 323. The scraper 333 scrapes off the dust on the surface of the dustproof plate 323 to prevent dust from clogging the air inlet 12 of the heat dissipation part 2. At the same time, the fan 213 inside the outer casing 211 starts to rotate, accelerating the air circulation inside the outer casing 211 and increasing the airflow speed into the engine compartment. The pump 222 inside the water tank 221 starts, delivering coolant to the condenser 223. After the condenser 223 cools the coolant, it returns the coolant to the water tank 221 through the conduit 224, forming an internal circulation. The heat sink 225 on the conduit 224 dissipates the coolant's chill, cooling the air passing inside the outer shell 211 and further improving the heat dissipation effect. The air flows rapidly under the action of the fan 213, and after being cooled, it rapidly cools the components inside the compartment, increasing the heat dissipation effect.

[0048] Reference Figures 3-10 As an optional embodiment, a high-efficiency heat dissipation wind turbine nacelle is provided, including a support part 1 including a nacelle body 11 disposed on the outside of the outer shell 211, an air inlet 12 disposed on the nacelle body 11, and an air outlet 13 disposed on the nacelle body 11.

[0049] Furthermore, the adjustment unit 4 includes a spoiler 41, which includes a baffle 411 disposed inside the cabin body 11 and an adjustment bearing 412 disposed on the baffle 411.

[0050] The adjusting bearing 412 is used to control the rotation of the baffle 411. The baffle 411 is used to turbulent the natural wind entering from the air inlet 12, so that all the air entering the cabin body enters the heat dissipation section 2.

[0051] Furthermore, the adjustment unit 4 also includes an adjustment component 42, which includes an electric push rod 421 disposed on the engine compartment body 11, a crossbar 422 disposed on the electric push rod 421, a sliding rod 423 disposed on the crossbar 422, a sliding groove 424 formed on the engine compartment body 11, and a connecting groove 425 disposed on the baffle 411.

[0052] The electric push rod 421 is located at the upper end of the cabin body, and its output end is fixed to the rear end of the crossbar 422, used to control the forward and backward movement of the crossbar 422. The sliding rod 423 is located on the lower left and right sides of the crossbar 422. Two sliding grooves 424 are formed on the main body of the cavity, and the sliding rod 423 is located inside them. A connecting groove 425 is formed at the upper end of the baffle 411, and the end of the sliding rod 423 is located inside the connecting groove 425, used to drive the baffle 411 to rotate.

[0053] Preferably, the horizontal bar 422 is moved by the operation of the electric push rod 421, and when the horizontal bar 422 moves, it will drive the two sliding rods 423 on the lower side to move together. When the sliding rods 423 move, they will cooperate with the connecting groove 425 to drive the baffle 411 to rotate. When the heat dissipation effect is insufficient, the rotation of the baffle 411 changes the gas path inside the cabin, so that all the internal air passes through the heat dissipation part 2 to cool the air and increase the heat dissipation effect.

[0054] Furthermore, the adjusting member 42 also includes a drainage member 43, which includes a groove 431 disposed on the outer casing 211, a shaped block 432 disposed inside the groove 431, a coil spring 433 disposed inside the shaped block 432, and a heat dissipation hole 434 disposed on the shaped block 432.

[0055] The groove 431 is designed to hold the irregular block 432. The irregular block 432 is composed of two quarter-cylinders, and multiple heat dissipation holes 434 are provided at the rear end of the irregular block 432. A coil spring 433 is provided on the shaft of the irregular block 432 to control the irregular block 432 to return to its original position.

[0056] Preferably, when the baffle 411 blocks the airflow inside the cabin body, the end of the baffle 411 will squeeze the front end of the irregular block 432, causing the rear end of the irregular block 432 to rotate. The internal heat dissipation hole 434 will appear on the outside of the outer shell 211, and the air cooled by the heat dissipation part 2 will be discharged through the heat dissipation hole 434 and discharged to both sides of the outer shell 211 to cool the heat source around the outer shell 211.

[0057] In summary: When the cabin's heat dissipation effect is insufficient, the controller activates the electric push rod 421, which drives the crossbar 422 and sliding rod 423 to move, thereby driving the baffle 411 to rotate and block the airflow inside the cabin. At this time, the end of the baffle 411 presses against the front end of the irregular block 432, causing the irregular block 432 to rotate around the shaft spring 433. The part with the heat dissipation hole 434 at the rear end rotates to the outside of the outer shell 211, so the air cooled by the heat dissipation part 2 is discharged to both sides of the outer shell 211 through the heat dissipation hole 434, cooling the surrounding heat source. When the cabin temperature returns to normal, the controller causes the electric push rod 421 to operate in the opposite direction, the crossbar 422 moves backward, the baffle 411 rotates, and the irregular block 432 resets under the action of the spring 433, and the cabin returns to the normal heat dissipation mode.

[0058] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
