Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a heat dissipation device for a wind turbine power module. Background Technology

[0002] As a key piece of equipment in clean energy power generation, wind turbines rely heavily on their core power conversion modules (such as IGBT modules) for energy conversion and transmission. These modules generate significant amounts of heat during operation, and their temperature directly impacts the turbine's efficiency, stability, and the lifespan of its core components. Therefore, efficient and reliable heat dissipation devices are crucial for ensuring the safe, stable, and long-term operation of wind turbines, especially high-power ones. How to quickly and evenly dissipate and cool the heat generated by the power modules, preventing localized overheating, remains a continuous challenge in wind turbine cooling design.

[0003] Currently, the heat dissipation design of wind turbine power modules typically employs forced air cooling combined with a heat sink housing and internal heat dissipation fins, vapor chambers, and other structures. Common cooling fans are mostly fixed in place, with their exhaust positions relatively static. This design has significant limitations: a fixed-position fan cannot dynamically adjust to the potential uneven temperature distribution within the power module, resulting in airflow that cannot accurately cover the areas most in need of cooling, easily creating heat dissipation blind spots at specific hotspots. When the power module is large or the heat load distribution is uneven, traditional fixed air cooling methods struggle to achieve efficient, uniform, and energy-saving heat dissipation, hindering further improvements in wind turbine power density and reliability. Utility Model Content

[0004] This utility model provides a heat dissipation device for a wind turbine power module, which achieves dynamic coverage of the heat dissipation airflow by driving a movable heat dissipation fan component with a motor, effectively improving heat dissipation efficiency and uniformity.

[0005] The technical solution adopted by this utility model is as follows: a heat dissipation device for a wind turbine power module, including a base plate, on which a power module body is fixedly installed. A heat dissipation shell is fitted on the upper part of the power module body. The bottom four corners of the heat dissipation shell are fixedly connected to the base plate by fixing rods. The top of the power module body is provided with heat dissipation fins and a heat spreader plate located inside the heat dissipation shell. A rack and pinion guide rail and a fixed guide rail are fixedly connected to the top two sides of the heat dissipation shell, respectively. A first movable side plate is slidably connected to one side of the rack and pinion guide rail, and a second movable side plate is slidably connected to one side of the fixed guide rail. A motor is fixedly connected to one side of the first movable side plate. The output shaft of the motor passes through the first movable side plate and is fixedly connected to a gear. The gear meshes with the rack at the top of the rack and pinion guide rail. The first movable side plate and the second movable side plate are fixedly connected by two connecting rods, and multiple cooling fans are provided between the two connecting rods located above the heat dissipation shell.

[0006] As a further improvement of this utility model, a first T-shaped slider is fixedly connected to the side of the first movable side plate near the rack and toothed guide rail, and a first T-shaped groove is provided on one side of the rack and toothed guide rail for the first T-shaped slider to slide.

[0009] As a further improvement of this utility model, the top wall of the heat dissipation shell is provided with a number of evenly distributed ventilation openings.

[0010] The beneficial effects of this utility model are as follows: This utility model uses a motor-driven gear and rack mechanism to drive the movable side plate connected to multiple cooling fans to move back and forth along the guide rail, realizing the overall translational sweeping of the cooling fan group above the heat sink shell. It can dynamically adjust the coverage area of ​​the cooling air force according to the heat load distribution, effectively eliminate local heat dissipation blind spots, significantly improve heat dissipation efficiency and uniformity, and avoid the problems of space occupation and increased energy consumption caused by adding a large number of fixed fans.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This utility model provides the following: Figure 1-4The wind turbine power module heat dissipation device shown includes a base plate 1, on which a power module body 2 is fixedly installed. A heat dissipation shell 3 is fitted on the upper part of the power module body 2. The bottom four corners of the heat dissipation shell 3 are fixedly connected to the base plate 1 by fixing rods 4. The top of the power module body 2 is provided with heat dissipation fins 5 and heat dissipation plate 6 located inside the heat dissipation shell 3. A rack and pinion guide rail 7 and a fixed guide rail 8 are fixedly connected to the top two sides of the heat dissipation shell 3, respectively. A first movable side plate 9 is slidably connected to one side of the rack and pinion guide rail 7, and a second movable side plate 10 is slidably connected to one side of the fixed guide rail 8. A motor 11 is fixedly connected to one side of the first movable side plate 9. The output shaft of the motor 11 passes through the first movable side plate 9 and is fixedly connected to a gear 12. The gear 12 meshes with the rack at the top of the rack and pinion guide rail 7. The first movable side plate 9 and the second movable side plate 10 are fixedly connected by two connecting rods 14, and multiple cooling fans 13 located above the heat dissipation shell 3 are provided between the two connecting rods 14.

[0020] like Figure 3 and Figure 4 As shown, in this utility model, a first T-shaped slider is fixedly connected to the first movable side plate 9 near the rack and pinion guide rail 7. A first T-shaped groove is provided on one side of the rack and pinion guide rail 7 for the first T-shaped slider to slide. A second T-shaped slider is fixedly connected to the second movable side plate 10 near the fixed guide rail 8. A second T-shaped groove is provided on one side of the fixed guide rail 8 for the second T-shaped slider to slide. Through the cooperative design of the T-shaped slider and the T-shaped groove, a more stable guiding effect can be provided for the movement of the movable side plate, ensuring that the first movable side plate 9 and the second movable side plate 10 slide smoothly along the predetermined track under the drive of the motor 11, avoiding deviation or shaking, thereby ensuring the stability of the cooling fan 13 during the movement process, so that the cooling airflow can always accurately cover the cooling area required by the power module.

[0021] like Figure 1 and Figure 2 As shown, the heat dissipation shell 3 has several evenly distributed heat dissipation holes on both sides of its side walls and several evenly distributed ventilation openings on its top wall. The heat dissipation holes can accelerate the discharge of hot air inside the heat dissipation shell 3 and form convection with the cold air outside. When the cooling fan 13 is working, the cold air is blown in from the top of the heat dissipation shell 3, and after passing through the heat dissipation fins 5 and the heat spreader 6, the heat is carried away and the air becomes hot air and is discharged from the heat dissipation holes on both sides.

[0022] Working Principle: In practical implementation, the wind turbine power module is first installed on the base plate. The main body of the power module is covered by a heat sink, and heat dissipation fins and a heat spreader are set on the top of the power module body for absorbing and conducting heat. When the motor is started, the motor's output shaft drives the gear to rotate. Since the gear meshes with the rack on the top of the rack guide rail, the rotation of the gear drives the first movable side plate to move along the rack guide rail. Because the first and second movable side plates are fixedly connected by a connecting rod, the second movable side plate moves synchronously along the fixed guide rail along with the first movable side plate, thereby achieving overall horizontal sweeping of multiple cooling fans above the heat sink.

[0023] When the power module generates heat during operation, the heat sink fins and heat spreader absorb the heat and conduct it into the interior space of the heat sink housing. At this time, the cooling fan operates, blowing cool external air into the heat sink housing through the vents at the top. As the cool air passes through the heat sink fins and heat spreader, it absorbs heat and becomes hot air. The hot air is then exhausted through the ventilation holes on both sides of the heat sink housing, completing a cooling cycle. Because the cooling fan can move dynamically under motor drive, it can precisely deliver cooling airflow to higher-temperature areas based on the real-time heat load at different locations on the power module, effectively solving the heat dissipation blind spot problem of traditional fixed air cooling methods and achieving efficient and uniform heat dissipation.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
