Description

Technical Field

[0001] The present invention belongs to the technical field of heat dissipation of generators, and in particular relates to a heat dissipation mechanism of a generator and an operating method thereof. Background Art

[0002] The core working component of a generator is its heat dissipation structure, which uses air or liquid cooling to rapidly transfer and dissipate heat, thereby ensuring the device's operating efficiency and service life. During this dynamic process, heat is transferred from the generator's interior to the external environment through conduction and convection. Under high load conditions, heat accumulation in localized high-temperature areas can significantly impact device performance. Inadequate heat dissipation within this area, or inability to flexibly adjust the cooling position, can lead to uneven heat distribution, compromising the generator's overall stability.

[0003] Existing generator cooling structures have limitations in terms of response speed, flexibility, and the ability to precisely cool localized high-temperature areas. For example, under high-load conditions, a fixed cooling layout struggles to fully adapt to varying heat loads in different areas, leading to excessive heat accumulation in some areas. Furthermore, traditional cooling structures typically rely on a single cooling mode with limited dynamic adjustment capabilities, which limits their adaptability under complex operating conditions.

[0004] Therefore, optimizing the design of the heat dissipation mechanism to improve cooling efficiency and meet diverse working conditions has become one of the key research directions. Summary of the Invention

[0020] The present invention provides a heat dissipation mechanism of a generator and an operating method thereof. Figure 1 To the attached Figure 7 The specific embodiments of the present invention are described in detail. Figure 1 and Figure 2As shown, the overall structure of the present invention includes a base 1, a power transmission unit, a transmission control unit and a heat dissipation adjustment unit. The base 1 serves as the core supporting component of the overall structure, and a plurality of power transmission units are arranged on it. These power transmission units are connected end to end through connectors to form a circumferentially distributed frame. Each power transmission unit is composed of a main body bracket 21 and a telescopic component 22 nested on the main body bracket 21. One end of the telescopic component 22 is connected to the base 1, and an elastic support member 23 is provided between the main body bracket 21 and the telescopic component 22. The connection between two adjacent main body brackets 21 is achieved through a hinge mechanism 24. The transmission control unit is installed on the base 1 and is linked with the power transmission unit to drive the power transmission unit to move in the radial direction, thereby changing the diameter of the circumferentially distributed frame. The heat dissipation adjustment unit is provided on the power transmission unit to adjust the heat dissipation position according to demand.

[0021] like Figure 3 and Figure 4 As shown, the main support 21 of the power transmission unit is a rigid structure, and a slide groove is provided inside it for accommodating the sliding part of the telescopic component 22. The outer end of the main support 21 is connected to the adjacent power transmission unit through a hinge mechanism 24. The hinge mechanism 24 adopts a hinge design, so that the main support 21 can rotate freely within a certain range. The elastic support member 23 is located between the telescopic component 22 and the main support 21, one end of which is fixed on the telescopic component 22, and the other end is in contact with the bottom of the main support 21. The elastic support member 23 acts on the telescopic component 22 through its own elastic force, so that the telescopic component 22 extends from the main support 21. At the same time, the design of the elastic support member 23 can effectively absorb the vibration generated by the power transmission unit during movement, and at the same time provide a certain reset force to ensure that the power transmission unit can return to its initial position after stopping driving.

[0022] The specific structure of the transmission control unit is as follows Figure 3 As shown, it includes a first drive unit 31 and a traction rope 33. The first drive unit 31 is fixed to the base 1, and its output end is equipped with a drive shaft 32. One end of the drive shaft 32 extending from the base 1 is connected to at least one traction rope 33, and the other end of the traction rope 33 is connected to the telescopic assembly 22. When the first drive unit 31 is activated, the drive shaft 32 rotates, tightening or loosening the traction rope 33, thereby pulling the telescopic assembly 22 to extend and retract along the radial direction of the main frame 21. The main frame 21 is also equipped with a second drive unit 34 to assist in driving the movement of the heat dissipation adjustment unit.

[0023] The specific structure of the heat dissipation adjustment unit is as follows: Figure 5As shown, it includes a sliding rail 41, a heat dissipation component 42 and a transmission rack 43. The sliding rail 41 is installed on the main support 21 and extends along the radial direction of the main support 21. The heat dissipation component 42 and the transmission rack 43 are installed on the sliding rail 41. The transmission rack 43 is engaged with the sliding rail 41. The output end of the second drive unit 34 is provided with a transmission gear 35, and the transmission gear 35 is engaged with the transmission rack 43. When the second drive unit 34 is started, the transmission gear 35 drives the transmission rack 43 to move along the sliding rail 41, thereby adjusting the position of the heat dissipation component 42. The specific structure of the heat dissipation component 42 is shown in FIG. Figure 5 As shown, it includes a base 421, an adjustable connecting rod 422, and a cooling element 423. The base 421 is fixed to the sliding track 41. The adjustable connecting rod 422 is provided on the base 421, and the cooling element 423 is provided at the other end of the adjustable connecting rod 422. The extension and retraction of the adjustable connecting rod 422 is controlled by a built-in threaded transmission mechanism. The threaded transmission mechanism includes a screw and a nut. One end of the screw is connected to the motor, and the other end engages the nut. The motor drives the screw to rotate by forward and reverse rotation, which in turn drives the nut to move along the screw's axis, achieving the extension and retraction of the adjustable connecting rod 422.

[0024] like Figure 6 As shown, the heat dissipation adjustment unit also includes a flexible guide frame 44, which is mounted on the main support 21, and the sliding rail 41 is fixed on the flexible guide frame 44. A guide groove is provided on the main support 21, and the flexible guide frame 44 can slide in the guide groove. The design of the flexible guide frame 44 allows the sliding rail 41 to have a certain degree of flexibility during movement. The flexible guide frame 44 is made of a high-strength composite material, and its surface is coated with a high-temperature resistant coating to enhance its stability and durability in high-temperature environments. The sliding rail 41 is made of a wear-resistant alloy, and its surface is specially treated to reduce the friction coefficient and extend its service life.

[0025] The specific structure of the transmission rack 43 is as follows: Figure 7 As shown, it includes a rack body 431 and a magnetic core 432 embedded in the rack body 431. The rack body 431 has multiple grooves evenly distributed along the circumference of the magnetic core 432. A magnetic block 433 is movably disposed in the groove, partially protruding from the rack body 431. The design of the magnetic core 432 enhances the strength and stability of the transmission rack 43. At the same time, the arrangement of the magnetic block 433 ensures that the transmission rack 43 maintains a tight mesh with the transmission gear 35 during movement, preventing tooth disengagement due to external interference.

[0026] The operating method of the present invention is as follows: First, the heat dissipation adjustment units on multiple power transmission units are moved to the outside of the power transmission units via the transmission control unit. At this point, the first drive unit 31 is activated, and the drive shaft 32 rotates, tightening the traction rope 33, thereby pulling the telescopic assembly 22 radially outward from the main frame 21. The movement of the telescopic assembly 22 increases the overall diameter of the circumferentially distributed frame, thereby moving the heat dissipation adjustment units to the outside of the power transmission units. Subsequently, the multiple power transmission units are connected end-to-end via connectors to form a circumferentially distributed frame. Finally, the transmission control unit drives the power transmission units to expand and contract radially, so that they conform to the outer wall of the generator. When internal cooling of the generator is required, the transmission control unit loosens the traction rope 33, causing the telescopic assembly 22 to move radially inward from the main frame 21, thereby moving the heat dissipation adjustment units to the inside of the power transmission units and conforming the circumferentially distributed frame to the inner wall of the generator.

[0027] During the operation of the generator, the external system monitors its internal temperature distribution in real time and adjusts the expansion and contraction of the power transmission unit and the position of the cooling element 423 based on the temperature data. When the external system detects a local high-temperature area, the transmission control unit drives the power transmission unit in the corresponding position to expand and contract, allowing the cooling element 423 to concentrate heat dissipation in that area. When the generator is under high load, the cooling element 423 is moved closer to the wall of the generator through the expansion and contraction action of the adjustable connecting rod 422; when the generator is under low load, the cooling element 423 is moved away from the wall of the generator through the reverse movement of the transmission rack 43. This dynamic adjustment method allows the cooling element 423 to flexibly adjust its position according to changes in the thermal load of the generator, thereby improving heat dissipation efficiency and reducing energy consumption.

[0028] The present invention achieves flexible adjustment of the cooling position through the telescopic motion of the power transmission unit and the dynamic adjustment of the heat dissipation adjustment unit, meeting the cooling requirements under different operating conditions. The design of the flexible guide frame 44 and transmission rack 43 further enhances the stability and reliability of the heat dissipation mechanism, providing a strong guarantee for the efficient operation of the generator.

[0029] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principle of the present invention is supplemented below with reference to a specific application scenario.

[0030] During the operation of the generator, the internal temperature distribution is first monitored in real time through the sensors of the external system, and the temperature data is transmitted to the control system. When the external system detects a local high-temperature area, the telescopic action of the power transmission unit is activated to adjust the position of the heat dissipation adjustment unit. Specifically, after the first drive unit 31 receives the control signal, its output shaft begins to rotate, driving the traction rope 33 to tighten or loosen. At this time, the movement of the traction rope 33 pulls the telescopic assembly 22 to move in the radial direction of the main bracket 21. Since the telescopic assembly 22 is connected to the hinge mechanism 24, the adjacent power transmission units can flexibly adjust their relative positions, thereby changing the overall diameter of the circumferential distribution frame. This process enables the heat dissipation adjustment unit to quickly approach the local high-temperature area, laying the foundation for subsequent precise cooling.

[0031] Then, the transmission control unit further drives the second driving unit 34 so that the transmission gear 35 at its output end engages with the transmission rack 43. Figure 4 As shown, the movement of the transmission rack 43 drives the heat dissipation assembly 42 on the sliding track 41 to move in the radial direction of the main support 21. The base 421 of the heat dissipation assembly 42 controls the telescopic movement of the adjustable connecting rod 422 through a threaded transmission mechanism. When the motor rotates forward, the rotation of the screw drives the nut to move axially, thereby extending the adjustable connecting rod 422; conversely, when the motor rotates reversely, the adjustable connecting rod 422 shortens. This design enables the cooling element 423 to accurately adjust its distance from the generator wall according to actual needs. For example, under high-load conditions, the cooling element 423 is moved closer to the generator wall through the extension action of the adjustable connecting rod 422 to enhance the heat dissipation effect; while under low-load conditions, the cooling element 423 is moved away from the wall through the shortening action of the adjustable connecting rod 422, thereby reducing energy consumption.

[0032] The design of the flexible guide frame 44 plays an important role in this process. Figure 5 As shown, the flexible guide frame 44 is mounted in the guide groove of the main frame 21 and can slide within a certain range. This flexibility allows the sliding track 41 to adapt to various generator wall shapes, ensuring optimal contact between the heat sink assembly 42 and the main frame. Furthermore, the flexible guide frame 44 is made of a high-strength composite material and coated with a high-temperature-resistant coating, ensuring stable performance in high-temperature environments and preventing thermal deformation that could reduce heat dissipation efficiency.

[0033] In addition, the structural design of the transmission rack 43 further improves the reliability of the system. Figure 6As shown, a magnetic core 432 is embedded in the rack body 431 of the transmission rack 43, and magnetic blocks 433 are movably mounted within grooves evenly distributed around the circumference. The magnetic blocks 433 partially protrude from the rack body 431 during transmission, maintaining tight engagement with the transmission gear 35 and preventing tooth stripping due to external interference. The transmission gear 35 has an involute tooth profile, with chamfered tooth tops and roots, effectively reducing impact forces during engagement and improving transmission efficiency. Furthermore, the tooth surfaces of the transmission rack 43 are hardened, enhancing their wear resistance and extending their service life.

[0034] When switching cooling modes, the transmission control unit adjusts the tension of the traction rope 33 to drive the telescopic assembly 22 radially along the main support 21, thereby moving the heat dissipation adjustment unit from the outside to the inside of the power transmission unit, or vice versa. When the heat dissipation adjustment unit is located outside the power transmission unit, the cooling element 423 adheres to the outer wall of the generator for external cooling; when the heat dissipation adjustment unit is located inside the power transmission unit, the cooling element 423 adheres to the inner wall of the generator for internal cooling. This switching between internal and external cooling modes can meet the heat dissipation requirements under different operating conditions and significantly improve heat dissipation efficiency.

[0035] In summary, the present invention achieves flexible adjustment of the cooling position through the telescopic motion of the power transmission unit, the precise actuation of the transmission control unit, and the dynamic adjustment of the heat dissipation adjustment unit. The design of the flexible guide frame 44 and transmission rack 43 further enhances the stability and reliability of the system, providing a strong guarantee for the efficient operation of the generator.
