Description

Technical Field

[0001] This invention relates to the field of cooler technology, specifically to a split-type air-cooled cooler for wind turbine components. Background Technology

[0002] A wind turbine is a power generation device that converts wind energy into electrical energy. It typically consists of blades, a hub, a nacelle, a tower, and a foundation. Wind turbines are generally installed at an altitude of 80 to 100 meters. During operation, the turbine generates a large amount of heat, which is usually cooled by an air-cooled condenser.

[0003] The utility model patent with publication number CN209510544U discloses a split-type air-cooled condenser for wind turbine units. This design separates the original, monolithic air-cooled condenser into several smaller, lighter sub-modules. This allows the condenser to be lifted and reassembled in stages during maintenance and replacement, reducing the requirements for hoisting. However, during the airflow to the heat sink, the large internal space and wide airflow range make it difficult to provide targeted cooling to specific areas of the heat sink. Summary of the Invention

[0004] To overcome the problem that, due to the large internal space and wide airflow range of the equipment, it is difficult to provide targeted airflow and cooling for the heat sink during the process of supplying air to the heat sink, this invention provides a split-type air-cooled cooler for wind turbine units, including a base, and further comprising:

[0005] The mounting bracket is set on the base;

[0006] A communication mechanism is provided above the base, the communication mechanism including a first heat sink plate, a second heat sink plate and a connecting pipe connecting the first heat sink plate and the second heat sink plate.

[0007] The air-cooling mechanism is installed above the fixed base. The air-cooling mechanism includes a lifting rod installed above the fixed base, a connecting cylinder connected to the telescopic end of the lifting rod, and a fan installed above the fixed base. The lifting rod is used to adjust the distance between the connecting cylinder and the fan.

[0008] Preferably, it further includes:

[0009] The outer casing installed inside the base and the first channel opened inside the outer casing;

[0010] The first fence installed on the outer casing and the cover plate connected to the first fence protect the equipment and prevent birds from entering the equipment.

[0011] Preferably, the communication mechanism further includes:

[0012] The mounting frame is installed above the base, and both the first heat sink and the second heat sink are installed inside the mounting frame;

[0013] The inlet and outlet pipes are located outside the first heat sink.

[0014] Preferably, the communication mechanism further includes:

[0015] A through slot is formed inside the second heat sink, and a sliding plate is slidably connected inside the through slot;

[0016] An extension plate located outside the sliding plate.

[0017] Preferably, the air-cooling mechanism further includes:

[0018] The fan is located inside the card holder, which is mounted on a fixed base.

[0019] Support plate installed outside the connecting cylinder and processing components located above the support plate;

[0020] The first magnetic block, located on the support plate, is used to control the height of the extension plate by magnetic force.

[0021] Preferably, the air-cooling mechanism further includes:

[0022] The branch pipe installed outside the connecting cylinder and the arc-shaped box connected to the branch pipe;

[0023] The second channel and the first air outlet, located inside the arc-shaped box, provide localized airflow to the first and second heat sinks.

[0024] Preferably, the processing component includes:

[0025] An adjusting rod installed on the support plate and an annular plate connected to the end of the adjusting rod away from the support plate;

[0026] The second fence is set outside the circular plate.

[0027] Preferably, the processing component further includes:

[0028] An annular groove formed inside the annular plate and an annular frame installed inside the annular groove;

[0029] The first telescopic rod is installed above the annular plate.

[0030] Preferably, the processing component further includes:

[0031] A first filter plate is provided on the telescopic end of the first telescopic rod and a collection groove is opened inside the first filter plate. The first filter plate has a first through hole inside and the collection groove is located at the edge of the first filter plate.

[0032] A second filter plate is disposed outside the first filter plate, and a second through hole is provided inside the second filter plate.

[0033] This invention provides a split-type air-cooled cooler for wind turbine components. It has the following beneficial effects:

[0034] 1. This wind turbine unit features a split-type air-cooled condenser. Through an air-cooling mechanism, it uses either exhaust or forced air to cool the internal components or to expel superheated gas from the equipment. During the forced airflow process, the connecting cylinder, located near the fan outlet, precisely directs the gas to the lower middle areas of the first and second heat dissipation plates for targeted cooling. Compared to existing equipment, this method offers more precise airflow positioning.

[0035] 2. This wind turbine unit features a split-type air-cooled condenser. Through a connecting mechanism, the inlet and outlet pipes correspond to the channels of the outer casing, which externally protects the inlet and outlet pipes, preventing direct exposure. Inlet and outlet pipes are installed outside multiple first heat dissipation plates, and electric valves are installed in both pipes. This allows for the selection of appropriate inlet and outlet pipes based on the relative position of the wind turbine unit and the equipment. The distance between the selected inlet and outlet pipes allows for adjustment of the coolant flow range and cooling time.

[0036] 3. This wind turbine unit features a split-type air-cooled condenser. By incorporating processing components, it filters the gas drawn into the equipment to reduce particulate impurities. Since both the first and second filter plates are made of elastic material, they undergo corresponding concave or convex deformations during gas entry and exit, thereby controlling the movement of impurity particles and causing them to detach from the filter holes and fall into the collection tank.

[0037] 4. The wind turbine unit is a split-type air-cooled cooler. By setting up a connecting mechanism and an air-cooling mechanism, when air is supplied to the first heat sink and the second heat sink, the first magnetic block controls the extension plate to descend by magnetic force, thereby expanding the space of the gas exhaust device and enabling the gas to be quickly discharged from the device after air is supplied to the first heat sink and the second heat sink.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0048] like Figures 1-8 As shown, the present invention provides a technical solution: a wind turbine component split-type air-cooled cooler, which is described below.

[0049] Including base 1, it also includes:

[0050] The mounting bracket 6 is installed on the base 1;

[0051] A connecting mechanism 5 is provided above the base 1. The connecting mechanism 5 includes a detachable first heat sink 502 and a second heat sink 505 provided above the base 1, and a connecting pipe 508 connecting the first heat sink 502 and the second heat sink 505. A pipe for circulating coolant is provided in the lower middle area of ​​the first heat sink 502 and the second heat sink 505. The pipes in the first heat sink 502 and the second heat sink 505 are connected by the connecting pipe 508. The first heat sink 502, the second heat sink 505 and the connecting pipe 508 are all detachable.

[0052] The air-cooling mechanism 7 is installed above the fixed base 6. The air-cooling mechanism 7 includes a lifting rod 706 set above the fixed base 6, a connecting cylinder 707 connected to the telescopic end of the lifting rod 706, and a fan 702 set above the fixed base 6. The lifting rod 706 is used to adjust the distance between the connecting cylinder 707 and the fan 702. The connecting cylinder 707 is open in the direction of the bottom of the fan 702, and the end of the connecting cylinder 707 away from the fan 702 is closed. The lifting rod 706 is set as an electric push rod.

[0053] A detachable housing 2 installed inside the base 1 and a first channel 8 opened inside the housing 2;

[0054] A first fence 3 and a cover plate 4 connected to the first fence 3 are installed on the outer shell 2. The cover plate 4 is set in an annular shape. A first net is installed in the annular area of ​​the cover plate 4, and a second net is installed outside the first fence 3.

[0055] When using the equipment, the integrated outer shell 2, cover plate 4 and first fence 3 are installed in the base 1. The connecting mechanism 5 is adjusted to allow the coolant in the wind turbine to flow into the connecting mechanism 5. The air-cooling mechanism 7 is adjusted so that the first heat sink 502, the second heat sink 505 and the coolant are air-cooled. The air-cooled coolant then returns to the wind turbine through the connecting mechanism 5, thus completing the air-cooling treatment of the coolant in the wind turbine.

[0056] The connecting mechanism 5 also includes:

[0057] The mounting frame 501 is installed above the base 1, and the first heat sink 502 and the second heat sink 505 are both installed inside the mounting frame 501.

[0058] The inlet pipe 503 and outlet pipe 504 are set on the outside of the first heat sink 502. Each first heat sink 502 is provided with an inlet pipe 503 and an outlet pipe 504. Electric valves are installed inside the inlet pipe 503 and the outlet pipe 504. Only the electric valves in the inlet pipe 503 and the outlet pipe 504 that need to flow coolant are opened. The inlet pipe 503 and the outlet pipe 504 are respectively connected to the inside of the wind turbine. Under the operation of the pump in the wind turbine, the coolant in the wind turbine enters the first heat sink 502, the connecting pipe 508, the second heat sink 505, the next connecting pipe 508, and the next first heat sink 502 in sequence through the inlet pipe 503. Then it enters the wind turbine through the designated outlet pipe 504 to complete the flow of coolant and the air cooling work. The inlet pipe 503 and the outlet pipe 504 correspond to the first channel 8 of the outer shell 2.

[0059] A through groove is formed inside the second heat sink 505 and a sliding plate 506 is slidably connected inside the through groove. A second telescopic rod is provided inside the through groove, and the telescopic end of the second telescopic rod is connected to the sliding plate 506.

[0060] An extension plate 507 is disposed outside the sliding plate 506, and magnetic material is disposed inside the extension plate 507.

[0061] The working process of transporting coolant using the connecting mechanism 5:

[0062] Before use, workers connect the coolant transport pipes in the wind turbine to the corresponding inlet pipes 503 and outlet pipes 504, and open the electric valves in the corresponding inlet pipes 503 and outlet pipes 504. The pump in the wind turbine is started, and the coolant flows through the inlet pipe 503 sequentially into the first heat sink 502, connecting pipe 508, second heat sink 505, next connecting pipe 508, and next first heat sink 502. It then flows through the designated outlet pipe 504 into the wind turbine, completing the coolant flow and air cooling process with the assistance of the air-cooling mechanism 7.

[0063] By setting up the connecting mechanism 5, the inlet pipe 503 and the outlet pipe 504 correspond to the channels of the outer casing 2, and the outer casing 2 protects the inlet pipe 503 and the outlet pipe 504 from direct exposure. The inlet pipe 503 and the outlet pipe 504 are set outside the multiple first heat dissipation plates 502, and electric valves are installed in both the inlet pipe 503 and the outlet pipe 504. This allows for the selection of appropriate inlet pipes 503 and 504 according to the relative position of the wind turbine and the equipment. The flow range and cooling time of the coolant can be adjusted according to the selected distance between the inlet pipe 503 and the outlet pipe 504.

[0064] The air-cooling mechanism 7 also includes:

[0065] The card holder 701 is set on the fixed base 6, the fan 702 is set inside the card holder 701, and the card holder 701 has a channel inside;

[0066] The support plate 703 installed outside the connecting cylinder 707 and the processing component 704 disposed above the support plate 703, the support plate 703 and the extension plate 507 are angularly aligned;

[0067] The first magnetic block 705 is disposed on the support plate 703;

[0068] The branch pipe 708 installed outside the connecting cylinder 707 and the arc-shaped box 709 connected to the branch pipe 708 are connected to each other.

[0069] The second channel 710 and the first air outlet are located inside the arc-shaped box 709.

[0070] The process of using the air-cooling mechanism 7 to perform air-cooling heat dissipation on the first heat sink 502 and the second heat sink 505:

[0071] When the fan 702 is started in the air supply mode, the lifting rod 706 is also started. The lifting rod 706 drives the connecting cylinder 707, the support plate 703, and the first magnetic block 705 to move upward. The connecting cylinder 707 corresponds to the air outlet position of the fan 702. Under the action of magnetic force, the extension plate 507 moves downward under the attraction of the first magnetic block 705. At this time, the sliding plate 506 connected to the extension plate 507 slides down inside the through groove, and the second telescopic rod is squeezed, which expands the space for the gas to be discharged from the equipment for the air supply operation.

[0072] The fan 702 draws the gas from above into the connecting cylinder 707. The gas passes through the connecting cylinder 707 and enters the branch pipe 708 and the arc-shaped box 709 in sequence. It then moves outward through the first air outlet of the arc-shaped box 709 to the lower middle part of the first heat sink 502 and the second heat sink 505 to perform air cooling at the corresponding positions.

[0073] When the fan 702 is started in exhaust mode, the lifting rod 706 is in the initial state. At this time, the connecting cylinder 707 is away from the fan 702, the second telescopic rod is in the initial state, and the extension plate 507 is in the highest position. The fan 702 draws the superheated gas in the equipment upward to the outside of the equipment.

[0074] By setting up the connecting mechanism 5 and the air-cooling mechanism 7, when air is supplied to the first heat sink 502 and the second heat sink 505 for heat dissipation, the first magnetic block 705 controls the extension plate 507 to descend by magnetic force, expanding the space of the gas exhaust device, so that the gas can be quickly discharged from the device after air is supplied to the first heat sink 502 and the second heat sink 505.

[0075] By setting up the air-cooling mechanism 7, the internal parts of the equipment are cooled by exhaust or supply air, or the overheated gas inside the equipment is extracted to the outside. During the air supply process, the connecting cylinder 707 is close to the air outlet of the fan 702, which specifically transports the gas to the lower middle area of ​​the first heat sink 502 and the second heat sink 505 to perform air supply and heat dissipation work at the corresponding locations. Compared with existing equipment, the air supply position is more accurate.

[0076] Processing component 704 includes:

[0077] An adjusting rod 7041 and an annular plate 7042 connected to the end of the adjusting rod 7041 away from the support plate 703 are installed on the support plate 703.

[0078] A second fence 7043 is provided outside the annular plate 7042, and the second fence 7043 is made of an elastic material.

[0079] An annular groove 7049 is formed inside the annular plate 7042 and an annular frame 7044 is installed inside the annular groove 7049;

[0080] The first telescopic rod 7045 is installed above the annular plate 7042;

[0081] The first filter plate 7046 is provided on the telescopic end of the first telescopic rod 7045 and the collection groove 7047 is opened inside the first filter plate 7046. The first filter plate 7046 has a first through hole inside.

[0082] The second filter plate 7048 is disposed outside the first filter plate 7046. The second filter plate 7048 has a second through hole inside. Both the first filter plate 7046 and the second filter plate 7048 are made of elastic material.

[0083] The process of using processing component 704 to filter the air supplied by fan 702:

[0084] As the blower 702 is switched to the air supply mode, the blower 702 begins to draw gas from outside the equipment from above. The gas first comes into contact with the first filter plate 7046 and the second filter plate 7048 located above the blower 702. The gas moves downward through the filter holes, and impurities are trapped on the filter holes. During the process of the blower 702 drawing gas, the first filter plate 7046 and the second filter plate 7048 are recessed downward.

[0085] As the fan 702 is switched to exhaust mode, it begins to draw air from inside the equipment. The gas is discharged from the top. As the gas moves toward the first filter plate 7046 and the second filter plate 7048, the first filter plate 7046 and the second filter plate 7048 begin to bulge upward, promoting the movement of impurity particles into the collection tank 7047.

[0086] By setting up the processing component 704, the gas drawn into the equipment is filtered to reduce particulate impurities entering the equipment. Since both the first filter plate 7046 and the second filter plate 7048 are made of elastic material, the first filter plate 7046 and the second filter plate 7048 undergo corresponding concave or convex deformations during the process of gas entering and leaving the equipment, thereby controlling the movement of impurity particles.

[0087] Working Principle: When using the equipment, the integrated outer shell 2, cover plate 4, and first enclosure 3 are installed in the base 1. Workers connect the coolant transport pipes from the wind turbine to the corresponding inlet pipes 503 and outlet pipes 504, and open the electric valves in the corresponding inlet and outlet pipes 503 and 504. The pump in the wind turbine is started, and the coolant from the wind turbine flows through the inlet pipe 503 sequentially into the first heat sink 502, connecting pipe 508, second heat sink 505, next connecting pipe 508, and next first heat sink 502. It then flows through the designated outlet pipe 504 into the wind turbine, completing the coolant flow and air cooling process with the assistance of the air-cooling mechanism 7.

[0088] When the fan 702 is started in the air supply mode, the lifting rod 706 is also started. The lifting rod 706 drives the connecting cylinder 707, the support plate 703, and the first magnetic block 705 to move upward. The connecting cylinder 707 corresponds to the air outlet position of the fan 702. Under the action of magnetic force, the extension plate 507 moves downward under the attraction of the first magnetic block 705. At this time, the sliding plate 506 connected to the extension plate 507 slides down inside the through groove, and the second telescopic rod is squeezed, which expands the space for the gas to be discharged from the equipment for the air supply operation.

[0089] The fan 702 draws the gas from above into the connecting cylinder 707. The gas passes through the connecting cylinder 707 and enters the branch pipe 708 and the arc-shaped box 709 in sequence. It then moves outward through the first air outlet of the arc-shaped box 709 to the lower middle part of the first heat sink 502 and the second heat sink 505 to perform air cooling at the corresponding positions.

[0090] When the fan 702 is started in exhaust mode, the lifting rod 706 is in the initial state. At this time, the connecting cylinder 707 is away from the fan 702, the second telescopic rod is in the initial state, and the extension plate 507 is in the highest position. The fan 702 draws the superheated gas in the equipment upward to the outside of the equipment.

[0091] As the blower 702 is switched to the air supply mode, the blower 702 begins to draw gas from outside the equipment from above. The gas first comes into contact with the first filter plate 7046 and the second filter plate 7048 located above the blower 702. The gas moves downward through the filter holes, and impurities are trapped on the filter holes. During the process of the blower 702 drawing gas, the first filter plate 7046 and the second filter plate 7048 are recessed downward.

[0092] As the fan 702 is switched to exhaust mode, it begins to draw air from inside the equipment. The gas is discharged from the top. As the gas moves toward the first filter plate 7046 and the second filter plate 7048, the first filter plate 7046 and the second filter plate 7048 begin to bulge upward, promoting the movement of impurity particles into the collection tank 7047.

[0093] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
