Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically to a generator with high-efficiency heat dissipation. Background Technology

[0002] Existing generators typically employ air cooling, relying on fans to expel internal heat. However, in enclosed or poorly ventilated environments, air cooling efficiency is significantly reduced, making effective heat dissipation difficult. Adding vents to improve ventilation can easily introduce dust and moisture, affecting the generator's lifespan. Furthermore, the generator casing and output shaft are often bolted together; frequent disassembly for bearing lubrication can lead to thread wear, reducing connection reliability. These issues result in significant shortcomings in the heat dissipation performance and ease of maintenance of existing generators.

[0003] Chinese Patent Publication No. CN221728088U discloses a generator housing for a generator set. In terms of heat dissipation, condensate is injected into a sealed cavity inside the generator housing through a condensate pipe. As the water flows along the cavity, it absorbs the heat generated during generator operation. The water is then discharged through a drain pipe and circulated to an external condensation device for cooling and reuse. This design replaces traditional air-cooled heat dissipation in a sealed environment, avoiding low heat dissipation efficiency due to insufficient air circulation and reducing the risk of dust and moisture intrusion, thus significantly improving heat dissipation and extending generator life. Regarding the connection structure, a mechanical linkage design of a positioning rod and a retaining sleeve is adopted: during installation, the generator port is aligned with the positioning rod, the retaining sleeve is pushed to slide along the guide groove, and the retaining sleeve is rotated to embed the guide block into the groove for fixation. Rubber gaskets are used to increase friction and stabilize the connection. During disassembly, the retaining sleeve is rotated in the opposite direction to disengage the guide block from the groove and slide it away along the guide groove, allowing for quick separation of the port from the housing. This structure avoids the thread wear problem caused by frequent disassembly of traditional bolted connections, simplifies the maintenance process, and facilitates regular lubrication or maintenance of the output shaft bearing. However, in this patent, the heat emitted by the generator is naturally discharged from the heat dissipation vent, resulting in low heat dissipation efficiency of the generator.

[0004] Therefore, this application provides a generator with high-efficiency heat dissipation to solve the above problems. Utility Model Content

[0005] To address the aforementioned issues, a high-efficiency heat dissipation generator is provided. This generator utilizes synchronous shaft rotation to drive the fan blades and water-cooling components for coordinated heat dissipation, thus solving the problem of low efficiency in natural heat dissipation. The generator's front and rear shafts are fixedly mounted on bases. The fan blades are connected to the shafts through a central through-hole, with a limiting perforation within the through-hole engaging with a limiting block on the base to achieve synchronous rotation. Nuts are tightened to prevent detachment. During shaft rotation, the fan blades forcefully guide airflow through the heat dissipation holes at both ends of the housing, creating strong convection and accelerating heat dissipation. Simultaneously, the water-cooling components between the housing and the generator body absorb internal heat through a circulating cooling medium. This combination of air-cooling and water-cooling mechanisms significantly improves heat exchange efficiency, ensuring continuous and stable generator operation.

[0006] To address the problems of existing technologies, this utility model provides a high-efficiency heat dissipation generator, comprising a generator body, with mounting bases fixedly connected to the front and rear shafts of the generator body. Fan blades are mounted on the mounting bases, and a through hole adapted to the shaft is formed at the center of each fan blade. A limiting hole is formed in the through hole, and a limiting block adapted to the limiting hole is provided on the mounting base. When the fan blade is mounted on the mounting base, the limiting block is inserted into the limiting hole. A gasket is mounted on the side of the fan blade away from the mounting base, and a nut to prevent the fan blade from falling off is mounted on the side of the gasket away from the fan blade. A generator housing is mounted outside the generator body, with several heat dissipation holes formed at both ends of the generator housing. A water-cooling assembly for accelerated cooling is installed between the generator housing and the generator body.

[0007] Preferably, the water-cooling assembly includes a condensate pipe that fills the space between the generator housing and the generator body, with an inlet pipe connected to the condensate pipe and an outlet pipe connected to the condensate pipe.

[0008] Preferably, the generator housing has through holes adapted to the water inlet pipe and the water outlet pipe, and the water inlet pipe and the water outlet pipe pass through the through holes to exit the generator housing.

[0009] Preferably, a positioning rod is welded to the side of the generator housing near the output end, a retaining sleeve is fitted on the surface of the positioning rod, a limiting base is provided on the positioning rod, and a limiting insertion rod is provided on the retaining sleeve. When the retaining sleeve is fitted on the positioning rod, the limiting insertion rod is inserted into the limiting base.

[0010] Preferably, the limiting base has a plurality of mounting slots, the mounting slots including insertion slots and limiting slots, and the end of the limiting rod is provided with a limiting block. During installation, the limiting block of the limiting rod passes through the insertion slot until the sleeve abuts against the limiting base. During fixing, the limiting block rotates into the limiting slot.

[0011] Preferably, a rubber gasket is provided between the sleeve and the limiting base.

[0012] Preferably, each of the four corners of the bottom of the generator housing is bolted with a support leg, and the bottom of the support leg is provided with anti-slip texture.

[0013] Preferably, the outer surface of the generator housing is provided with a corrugated pattern.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This utility model significantly improves the heat exchange efficiency inside and on the surface of the generator by using a dual heat dissipation mechanism of forced convection generated by the synchronous rotation of the fan blades and the shaft and the circulating cooling of the water cooling component, thus solving the problem of slow heat dissipation caused by traditional heat dissipation relying on natural convection.

[0016] 2. This utility model adopts a positioning rod, a sleeve and a limit base with a plug-in groove and a limit groove, combined with the elastic pressing effect of the rubber gasket, to realize the quick installation and disassembly of the generator port, avoid the thread wear caused by frequent disassembly of traditional bolt connections, and improve the convenience of maintenance.

[0017] 3. This utility model enhances the friction between the outer shell and the mounting surface and increases the heat dissipation surface area by using the anti-slip texture design at the bottom of the support legs and the wave pattern structure on the surface of the generator housing. At the same time, it raises the outer shell to avoid direct contact with the ground, thus improving stability and optimizing passive heat dissipation. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 The generator described is a high-efficiency heat dissipation generator, comprising a generator body 1. Mounting bases 2 are fixedly connected to the front and rear shafts of the generator body 1. Fan blades 3 are mounted on the mounting bases 2. A through hole adapted to the shaft is opened at the center of the fan blades 3. A limiting hole 4 is opened in the through hole. A limiting block 5 adapted to the limiting hole 4 is provided on the mounting base 2. When the fan blades 3 are mounted on the mounting base 2, the limiting block 5 is inserted into the limiting hole 4. A gasket is installed on the side of the fan blades 3 away from the mounting base 2. A nut 6 to prevent the fan blades 3 from falling off is installed on the side of the gasket away from the fan blades 3. A generator housing 7 is mounted outside the generator body 1. Several heat dissipation holes 8 are opened at both ends of the generator housing 7. A water-cooling assembly 9 for accelerated cooling is installed between the generator housing 7 and the generator body 1.

[0027] In existing technologies, the heat emitted by generators is naturally dissipated through heat dissipation vents, resulting in slow heat dissipation efficiency. To address this issue, in this application, the front and rear shafts of the generator body 1 generate rotational power during operation, and the mounting base 2 is fixedly connected to the shafts and rotates synchronously with them. The fan blade 3 is fitted onto the shaft surface through a through hole at its center. A limiting hole 4 within the through hole engages with a limiting block 5 on the mounting base 2, preventing the fan blade 3 from shifting or sliding due to centrifugal force or vibration during shaft rotation. When the fan blade 3 is mounted on the mounting base 2, the limiting block 5 inserts into the limiting hole 4 to form a mechanical lock, ensuring the synchronous rotational stability of the fan blade 3 and the shaft. A gasket is attached to the end face of the fan blade 3 away from the mounting base 2 and tightened onto the threaded end of the shaft by a nut 6, creating axial clamping force to prevent the fan blade 3 from falling off the shaft.

[0028] The generator housing 7 encloses the generator body 1. Several heat dissipation holes 8 at both ends of the housing form airflow paths. When the fan blades 3 rotate at high speed with the shaft, the airflow generated by the fan blades 3 forms forced convection through the heat dissipation holes 8, expelling the heat generated inside the generator. The water-cooling assembly 9 between the generator housing 7 and the generator body 1 absorbs the heat generated by the generator operation through a circulating cooling medium. The coolant in the water-cooling pipes absorbs heat as it flows through the high-temperature areas of the generator, and then dissipates the heat to the environment through an external heat dissipation device, thus achieving a dual heat dissipation mechanism. The airflow generated by the fan blades 3 and the liquid circulation of the water-cooling assembly 9 work together to accelerate the heat exchange efficiency on the surface and inside of the generator body 1.

[0029] Reference Figures 1-4 As shown: The water-cooled assembly 9 includes a condensate pipe 10 that fills the space between the generator housing 7 and the generator body 1. The inlet of the condensate pipe 10 is connected to an inlet pipe 11, and the outlet of the condensate pipe 10 is connected to an outlet pipe 12.

[0030] The condensate pipe 10 fills the space between the generator housing 7 and the generator body 1. Cooling water is introduced into the condensate pipe 10 through the inlet pipe 11 connected to the inlet. When the generator is running, the heat generated by the generator body 1 is transferred to the area between the generator housing 7 and the generator body 1 through heat conduction and heat radiation. As the cooling water in the condensate pipe 10 flows through this area, it absorbs heat from the surface of the generator body 1 and the surrounding environment, gradually cooling down the high-temperature parts of the generator. The temperature of the cooling water rises after absorbing heat and is discharged from the condensate pipe 10 through the outlet pipe 12 connected to the outlet, forming a circulating cooling water path.

[0031] Reference Figure 4 and Figure 5 As shown: The generator housing 7 is provided with through holes adapted to the water inlet pipe 11 and the water outlet pipe 12, and the water inlet pipe 11 and the water outlet pipe 12 pass through the through holes to exit the generator housing 7.

[0032] The through-holes on the generator housing 7 are matched with the diameters of the inlet pipe 11 and the outlet pipe 12, allowing the inlet and outlet pipes 11 and 12 to pass through the through-holes and extend to the outside of the generator housing 7. The inner wall of the through-hole is tightly sealed to the outer surfaces of the inlet and outlet pipes 11 and 12 through a sealing structure to prevent leakage of cooling water as it flows through the through-holes, while allowing for minor displacement of the inlet and outlet pipes 11 and 12 due to thermal expansion and contraction or vibration during generator operation. The inlet pipe 11, after exiting the generator housing 7 through the through-hole, connects to an external cooling water source or circulating pump, continuously supplying low-temperature cooling water to the condensate pipe 10. The outlet pipe 12, after exiting the generator housing 7 through the through-hole, connects to an external radiator or cooling tower, discharging the high-temperature cooling water (after absorbing heat) to an external cooling device for cooling.

[0033] Reference Figure 5 and Figure 6 As shown: A positioning rod 13 is welded to the side of the generator housing 7 near the output end. A sleeve 14 is fitted on the surface of the positioning rod 13. A limiting base 15 is provided on the positioning rod 13. A limiting insertion rod 16 is provided on the sleeve 14. When the sleeve 14 is fitted on the positioning rod 13, the limiting insertion rod 16 is inserted into the limiting base 15.

[0034] A positioning rod 13 is welded to the side of the generator housing 7 near the output end. The positioning rod 13 extends perpendicularly to the surface of the housing as a support structure, and a sleeve 14 that can slide along the rod is fitted on its outer surface. A limiting base 15 is fixed on the rod of the positioning rod 13. The side wall of the sleeve 14 extends to form a limiting insertion rod 16. When the sleeve 14 moves axially along the positioning rod 13 to a preset position, the end of the limiting insertion rod 16 corresponds to the position of the limiting base 15 and is inserted into the slot of the limiting base 15, thus locking the position between the sleeve 14 and the positioning rod 13.

[0035] Reference Figure 5 and Figure 6 As shown: The limiting base 15 is provided with a plurality of mounting slots 17, the mounting slots 17 including insertion slots 18 and limiting slots 19. The end of the limiting rod 16 is provided with a limiting block 20. During installation, the limiting block 20 of the limiting rod 16 passes through the insertion slot 18 until the sleeve 14 abuts against the limiting base 15. When fixed, the limiting block 20 rotates into the limiting slot 19.

[0036] The limiting base 15 has several mounting slots 17, including insertion slots 18 and limiting slots 19. The end of the limiting rod 16 has a limiting block 20. During installation, the limiting block 20 of the limiting rod 16 is first aligned with the insertion slot 18 and inserted into the limiting base 15 through the guide path of the insertion slot 18 until the retaining sleeve 14 of the limiting rod 16 is fully in contact with the surface of the limiting base 15. At this time, the limiting block 20 moves with the limiting rod 16, passing through the insertion slot 18 and entering the interior of the limiting base 15. During fixing, the limiting rod 16 is rotated to adjust its position, causing the limiting block 20 to move from the insertion slot 18 to the limiting slot 19. The size and shape of the limiting slot 19 match the limiting block 20, locking the limiting block 20 into the limiting slot 19, thereby limiting the axial direction of the limiting rod 16 and achieving stable fixing. When the sleeve 14 abuts against the limiting base 15, the pressure of the contact surface further assists in fixing the limiting rod 16.

[0037] Reference Figure 6 As shown: A rubber gasket is provided between the card sleeve 14 and the limiting base 15.

[0038] During installation, the gasket fills the gap between the contact surfaces of the sleeve 14 and the limiting base 15, adapting to minor unevenness in the contact surfaces through its own elastic deformation, ensuring uniform pressure distribution when the sleeve 14 and the limiting base 15 are in contact. When the limiting rod 16 is fixed to the limiting groove 19 of the limiting base 15 by the limiting block 5, the gasket is compressed, generating a reverse force, increasing the frictional resistance between the sleeve 14 and the limiting base 15, and suppressing relative sliding caused by vibration or external force.

[0039] The generator housing 7 has support legs bolted to the four corners of its bottom, and the bottom of the support legs has anti-slip texture.

[0040] Support legs are bolted to the four corners of the bottom of the generator housing 7. These support legs are fixed to the four corners of the bottom of the generator housing 7 with bolts, providing a stable support structure for the generator housing 7. This maintains a certain distance between the housing and the mounting surface, preventing the bottom of the housing from directly contacting the ground or mounting surface, and reducing the risk of moisture and foreign object intrusion. The bottom of the support legs has anti-slip textures, which are concave-convex textures formed by machining the bottom surface of the support legs. When the support legs contact the mounting surface, the anti-slip textures increase friction by increasing the roughness of the contact surface, suppressing horizontal displacement caused by the generator's own vibration or external forces, and ensuring the generator housing 7 is placed stably.

[0041] The outer surface of the generator housing 7 is provided with a wave pattern.

[0042] The outer surface of the generator housing 7 is provided with a wave pattern. The wave pattern is a continuous undulating texture structure on the surface of the housing, which increases the contact area between the generator housing 7 and the external air and improves the heat dissipation surface area.

[0043] Working principle: The front and rear shafts of the generator body 1 are fixedly connected to the mounting base 2. The mounting base 2 engages with the limiting through-holes 4 of the fan blade 3 via limiting blocks 5, allowing the fan blade 3 to rotate synchronously with the shaft. The airflow generated by the fan blade 3 forms forced convection through the heat dissipation holes 8 at both ends of the generator housing 7, accelerating the dissipation of internal heat. A water-cooling assembly 9, including a condensate pipe 10, is installed between the generator housing 7 and the generator body 1. Cooling water enters the condensate pipe 10 through the inlet pipe 11, absorbs heat from the generator surface, and is discharged through the outlet pipe 12, forming a circulating cooling system. The outer surface of the generator housing 7 has corrugated patterns to increase the contact area and improve heat dissipation efficiency through air turbulence.

[0044] A positioning rod 13 is welded near the output end of the generator housing 7. A retaining sleeve 14 is fitted onto the positioning rod 13. The limiting rod 16 of the retaining sleeve 14 is locked in position via the insertion groove 18 and the limiting groove 19 of the limiting base 15. During installation, the limiting block 20 of the limiting rod 16 is inserted along the insertion groove 18 and, after rotation, engages with the limiting groove 19 for fixation. A rubber gasket is placed between the retaining sleeve 14 and the limiting base 15 to evenly distribute pressure and suppress slippage through elastic deformation. Support legs are bolted to the four corners of the bottom of the generator housing 7. Anti-slip grooves are formed on the bottom of the support legs to increase friction on the contact surface, prevent displacement, and simultaneously raise the housing to avoid direct contact with the ground.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
