Description

Technical Field

[0001] The present invention relates to the technical field of generators, and in particular provides a generator and a generator set with noise reduction and heat dissipation functions. Background Art

[0002] Internal combustion engine generator sets are typically "supporting core equipment" in power plants. Although not the primary power generation unit, they play a vital role in the safe operation and flexible scheduling of power plants. Their value lies in three key areas: emergency support (preventing power outages), peak load regulation (balancing grid fluctuations), and providing primary power generation in special scenarios (remote areas). In particular, they serve as an irreplaceable "last line of defense" in the emergency systems of nuclear power plants and large thermal / hydropower plants, which require high safety standards.

The sound waves between the multiple chambers interfere with each other, and some of the energy is converted into heat energy due to friction (friction between air molecules and the chamber walls), thereby weakening the sound energy. At the same time, by opening multiple pores on the wall of each independent chamber, the noise can be further weakened.

[0022] The following combination Figures 1 to 16 The embodiment shown describes the technical solution of the present invention: The embodiment of the present invention provides a generator with noise reduction and heat dissipation functions, such as Figures 1 to 6 As shown, the generator includes: a generator module 1, an internal combustion engine module 2, a housing 3, a cooling module 4 and a heat absorption pipe assembly 5.

[0023] Among them, the internal combustion engine module 2 is driven and connected to the generator module 1; the shell 3 is arranged along the outer wall 301 of the internal combustion engine module 2, and has a first gap 302 between the shell 3 and the outer wall 301; a sound insulation interlayer 303 is provided in the first gap 302, and a plurality of adjacent polygonal independent chambers 304 are opened in the sound insulation interlayer 303, and a plurality of pores 305 are opened on the wall surface of each independent chamber; adjacent polygonal independent chambers 304 can be connected by the pores 305; the heat absorption pipe assembly 5 is made of a thermally conductive material, including A plurality of U-shaped tubes 501, liquid inlet manifolds 502 and liquid outlet manifolds 503 are arranged in parallel, wherein the U-shaped tubes 501 are arranged in sequence along the outer wall 301 of the internal combustion engine module 2, and one end of the U-shaped tube 501 is connected to the liquid inlet manifold 502, and the other end is connected to the liquid outlet manifold 503; the liquid inlet manifold 502 is connected to the liquid outlet end of the cooling module 4, and the liquid outlet manifold 503 is connected to the liquid inlet end of the cooling module 4; wherein, a plurality of U-shaped tubes 501 are arranged in the first gap 302, and the shell 3 and the sound insulation interlayer 303 are both made of thermally conductive material.

[0024] In some embodiments, the material of the sound insulation interlayer 303 can be rock wool board, foamed iron nickel, etc., which can be both noise-isolating and heat-conducting; In this embodiment, the generator module 1 is used for energy conversion, which converts the mechanical energy generated by the internal combustion engine module 2 into electrical energy. During the operation of the generator module 1, the noise generated by the internal combustion engine module 2 propagates in the first gap 302 inside the shell 3 and is absorbed by the sound insulation interlayer 303 arranged inside the first gap 302. The material of the sound insulation interlayer 303 is preferably an aluminum honeycomb panel, which utilizes the resonance sound absorption effect of the honeycomb cavity and the closed first gap 302 to achieve physical isolation of noise propagation. The low-frequency vibration noise generated by the internal combustion engine module 2 is absorbed by multiple polygonal independent cavities. The sound waves in the polygonal independent chambers 304 are reflected and refracted multiple times, thereby extending the propagation path. The sound waves in the multiple polygonal independent chambers 304 interfere with each other, and part of the energy is converted into heat energy due to friction (friction between air molecules and the chamber wall), thereby weakening the sound energy. At the same time, by providing multiple pores 305 on the wall of each polygonal independent chamber 304, the large number of interconnected tiny pores 305 allow the sound waves to enter the pores 305 and generate friction and viscosity, converting the sound energy into heat energy, thereby further weakening the noise. In this way, the occurrence of noise is effectively reduced at the root. The heat absorption pipe assembly 5 is embedded in the sound insulation interlayer 303 and close to the internal combustion engine module 2, and cooperates with the cooling module 4 to realize the recycling of hot and cold water. When the temperature is the lowest, the cold water enters the U-shaped tube 501 from the liquid inlet manifold 502. The connector principle is used to achieve the same water level rise in the U-shaped tubes 501 of the multiple arrays. The high-temperature hot water generated after absorbing the heat generated by the internal combustion engine module 2 is simultaneously gathered in the liquid outlet manifold 503, and the high-temperature hot water is quickly diverted from the liquid outlet manifold 503 into the cooling module 4 through the pressure of the liquid pump 405. Through the cooperation of the cooling module 4, the first-level cooling of the hot water is achieved; compared with the S-shaped single-channel tube, the U-shaped tube 501 has a better cooling effect, thereby achieving rapid heat dissipation of concentrated heat areas. At the same time, the heat absorption tube assembly 5 is set in the first gap 302, that is, in the sound insulation interlayer 303, which can further take away the heat energy generated by the silencer; further, by setting the shell 3 and the sound insulation interlayer 303 to thermal conductive materials, part of the heat can be directly dissipated from the shell 3 to the air, further accelerating the heat dissipation efficiency.

[0025] An embodiment of the present invention provides a generator with noise reduction and heat dissipation functions. By providing a thermally conductive housing 3 on the outer surface of an internal combustion engine module 2 and multiple adjacent polygonal independent chambers 304 on the inner side of the housing 3, the low-frequency vibration noise generated by the internal combustion engine module 2 can be reflected and refracted multiple times within the chamber, thereby extending the propagation path. The sound waves between the multiple chambers interfere with each other, and some of the energy is converted into heat energy due to friction (friction between air molecules and the chamber walls), thereby weakening the sound energy. At the same time, by opening a plurality of pores 305 on the wall of each independent chamber, the noise can be further weakened. When the sound waves enter the numerous interconnected tiny pores 305, friction and viscosity occur in the pores 305, converting the sound energy into heat energy. In this way, the occurrence of noise is effectively reduced from the root.

[0026] Furthermore, by disposing the U-shaped tube 501 in the heat absorption tube assembly 5 and arranging it in parallel along the outer wall 301 of the internal combustion engine module 2, with one end connected to the liquid inlet manifold 502 and the other end connected to the liquid outlet manifold 503, the heat exchange liquid in the U-shaped tube 501 can have a shorter travel distance along the outer wall 301 of the internal combustion engine module 2, that is, it enters the U-shaped tube 501 at the lowest temperature, absorbs heat and immediately enters the liquid outlet manifold 503 and is then discharged; compared with the S-shaped single-channel heat exchange tube 4022, it has a better cooling effect; thereby, rapid heat dissipation of concentrated heat areas can be achieved. At the same time, the heat absorption tube assembly 5 is arranged in the first gap 302, that is, in the sound insulation interlayer 303, which can further take away the heat energy generated by the sound insulation; Furthermore, by setting the shell 3 and the sound insulation interlayer 303 to be thermally conductive materials, part of the heat can be directly dissipated from the shell 3 into the air, further accelerating the heat dissipation efficiency.

[0027] According to the generator provided by the embodiment of the present invention, Figure 1 、 Figures 6 to 8 As shown, the cooling module 4 includes a vortex tube 401 , a condensation tank 402 , a liquid storage tank 403 , a semiconductor refrigeration sheet 404 and a liquid pump 405 .

[0028] The vortex tube 401 has a cold end and a hot end for connecting to a high-pressure steam source. The condenser 402 includes a housing 4021 and a heat exchange tube 4022. The heat exchange tube 4022 is arranged in an S-shape inside the housing 4021. The housing 4021 has an air inlet 4023 at the top and an exhaust port 4024 at the bottom. The air inlet 4023 is connected to the cold end of the vortex tube 401. The liquid storage tank 403 has a first liquid inlet 4031 and a first liquid outlet 4032. The first liquid outlet 4032 is connected to one end of the heat absorption tube assembly 5, and the other end of the heat absorption tube assembly 5 is connected to the liquid inlet end of the heat exchange tube 4022. The first liquid inlet 4031 is connected to the liquid outlet end of the heat exchange tube 4022. The liquid storage tank 403 is provided with heat dissipation fins 4033, and a plurality of semiconductor cooling fins 404 are provided on the outer surface of the liquid storage tank 403. The liquid pump 405 is disposed at the first liquid outlet 4032 and is used to drive the condensed liquid to circulate.

[0029] In this embodiment, the vortex tube 401 generates a temperature separation effect by compressing gas, separating the high-temperature airflow from the low-temperature airflow to achieve graded energy utilization; an S-shaped heat exchange tube 4022 is provided inside the condenser box 402 to improve the heat exchange efficiency by extending the coolant flow path; the liquid storage tank 403 can be welded with aluminum heat dissipation fins 4033 on the surface to accelerate the cooling of the liquid by increasing the heat dissipation surface area; the semiconductor refrigeration plate 404 realizes precise temperature control of the outer surface of the liquid storage tank 403 by controlling the current direction.

[0030] High-pressure steam drives vortex tube 401 to generate low-temperature airflow. This low-temperature airflow enters through air inlet 4023 on condenser 402 and exchanges heat with the circulating coolant in S-shaped heat exchange tube 4022. Simultaneously, the high-temperature airflow after heat exchange flows into housing 3 through exhaust port 4024, where it is recycled through vortex tube 401 to generate low-temperature airflow. After absorbing heat from the internal combustion engine in heat absorption tube assembly 5, the coolant is pressurized by liquid pump 405 and enters heat exchange tube 4022. Within the S-shaped tube, it fully contacts the counterflowing low-temperature airflow, achieving cooling. The condensing tank 402 is connected to the liquid storage tank 403 through a pipeline. The coolant cooled by the heat exchange tube 4022 flows back to the liquid storage tank 403 through the first liquid inlet 4031, and realizes secondary cooling through the cooperation of the heat dissipation fins 4033 and the semiconductor refrigeration plate 404. Among them, the semiconductor refrigeration plate 404 is driven by electric energy to continuously absorb the heat from the surface of the liquid storage tank 403, and the heat dissipation fins 4033 dissipate the heat to the environment through natural air convection. After cooling, the coolant flows into the liquid pump 405 from the first liquid outlet 4032, and flows into the heat exchange tube 4022 under the pressure of the liquid pump 405, thereby realizing the circulation of the coolant and avoiding the energy loss of the traditional open cooling system.

[0031] This invention achieves rapid heat transfer by placing a heat-absorbing pipeline directly at the internal combustion engine's heat source, combining a vortex tube 401 with a semiconductor refrigeration dual cooling mechanism. Compared to systems that rely solely on air cooling, this invention combines a coolant circulation system with gas vortex cooling, creating a multi-stage heat exchange structure within a limited space, significantly improving heat dissipation efficiency per unit volume.

[0032] The above technical solution effectively reduces cooling system energy consumption. The shortened coolant circulation path improves heat exchange efficiency. The combined use of semiconductor cooling fins 404 and heat sink fins 4033 achieves a synergistic effect of passive heat dissipation and active cooling. The vortex tube 401 utilizes the high-pressure steam in a graded manner, reducing additional energy consumption. The S-shaped heat exchange tube 4022 design enables efficient heat exchange within a compact space. The closed-loop cooling system prevents leakage of the cooling medium and reduces noise during operation.

[0033] According to the generator provided by the embodiment of the present invention, Figure 4 and Figure 5 The sound insulation interlayer 303 is filled with sound absorbing material.

[0034] In some embodiments, the sound-absorbing material may be glass fiber cotton, polyester fiber felt, or foamed ceramic material, etc., as long as it can absorb and dissipate the sound wave energy.

[0035] In this embodiment, the sound insulation layer 303 is internally constructed as a plurality of polygonal independent chambers 304 interconnected by pores 305. The function of the structure is to change the propagation path of sound waves through the cavity geometry. By filling the pores 305 within the polygonal independent chambers 304 with sound-absorbing material, the sound wave energy is absorbed and dissipated.

[0036] Specifically, when sound waves enter the sound-insulating interlayer 303, high-frequency sound waves pass through pores 305 into the sound-absorbing material, where they are converted into heat energy due to friction between the material fibers or pores 305. Low-frequency sound waves are reflected multiple times between the inner walls of the polygonal independent chamber 304, attenuating the sound wave energy due to the extended path. Filling the adjacent chambers with sound-absorbing material creates a continuous sound-absorbing medium. While maintaining the chamber structure's ability to block low-frequency sound waves, the material's penetration enhances the absorption efficiency of high-frequency sound waves, achieving comprehensive attenuation of noise across a wide frequency range.

[0037] The present invention forms a dual noise reduction mechanism of physical blocking and material sound absorption through the synergistic effect of filling sound-absorbing materials and cavity structure, breaking through the technical bottleneck of low absorption efficiency of high-frequency sound waves by a single cavity structure.

[0038] Through the above technical solution, the present application can simultaneously suppress the high-frequency mechanical noise and low-frequency vibration noise generated during the operation of the internal combustion engine module 2, so that the equipment's own noise reduction capability covers a wider sound wave frequency band, and the purpose of noise control can be achieved without relying on external machine room sound insulation.

[0039] According to the generator provided by the embodiment of the present invention, Figure 9 As shown, the generator with noise reduction and heat dissipation functions further includes: a support 406 , a first shock absorbing assembly 407 , a support member 408 and a second shock absorbing assembly 409 .

[0040] Among them, the support 406 serves as the basic supporting structure, the first shock-absorbing assembly 407 is arranged on the support 406, there are multiple support members 408, and one end of a single support member 408 is connected to the internal combustion engine module 2, and the other end is connected to the first shock-absorbing assembly 407, and the second shock-absorbing assembly 409 is connected to the support 406 at one end, and the other end is connected to the internal combustion engine module 2.

[0041] In this embodiment, the support 406, the first shock absorbing assembly 407, the second shock absorbing assembly 409, and the support member 408 constitute a shock absorbing module for reducing the vibration generated by the operation of the generator, wherein the support 406 provides a stable installation base for the shock absorbing system; the first shock absorbing assembly 407 is used to absorb the high-frequency vibration energy transmitted by the internal combustion engine module 2; the support member 408 disperses the vibration energy to the first shock absorbing assembly 407 through a multi-point distribution design; the second shock absorbing assembly 409 has a vibration transmission path different from the first shock absorbing assembly 407, further buffering the low-frequency vibration energy.

[0042] Specifically, the vibrations generated during operation of the internal combustion engine module 2 are transmitted to the first shock-absorbing assembly 407 via the support member 408, where initial energy absorption is performed by a rubber shock-absorbing pad or spring damper. Because the support member 408 is connected at multiple distribution points, the vibration energy is dispersed to different shock-absorbing units, avoiding local overload. Simultaneously, the second shock-absorbing assembly 409 forms a second vibration transmission path directly between the internal combustion engine module 2 and the support 406 through a hydraulic damper or air spring, providing secondary buffering for low-frequency vibrations not eliminated by the first shock-absorbing assembly 407. The two-stage shock-absorbing system achieves broadband vibration isolation through shock-absorbing units of different stiffness and multi-path energy transfer.

[0043] The present invention arranges two-stage components with different shock-absorbing characteristics and constructs a multi-path vibration transmission channel, so that high-frequency and low-frequency vibration energy are absorbed in layers. At the same time, the multi-point distribution design of the support member 408 avoids excessive concentration of vibration energy at a single connection point.

[0044] Through the above technical solution, this application effectively reduces the vibration transmission intensity of the internal combustion engine module 2 during operation, reducing structural resonance and noise radiation caused by mechanical vibration. The synergistic effect of the two-stage damping system improves the overall stability of the equipment, avoiding mechanical fatigue problems such as loose bolts and weld cracking caused by long-term vibration, while also reducing airborne noise caused by vibration transmitted outward through the housing 3.

[0045] According to the generator provided by the embodiment of the present invention, Figure 4 、 Figure 10 and Figure 11 As shown, the generator with noise reduction and heat dissipation functions also includes: a vibration energy collector 6, which is arranged between the support 406 and the internal combustion engine module 2 and is in contact with the internal combustion engine module 2, and the vibration energy collector 6 is electrically connected to the battery of the semiconductor refrigeration plate 404.

[0046] In this embodiment, the vibration energy collector 6 refers to a device that converts mechanical vibration energy into electrical energy, which can be specifically implemented using piezoelectric ceramic materials or electromagnetic induction devices. It is arranged on the mechanical conduction path between the support 406 and the internal combustion engine module 2 to capture vibration energy.

[0047] Among them, the battery of the semiconductor refrigeration plate 404 refers to an energy storage device that supplies power to the semiconductor refrigeration element, which can be specifically implemented by a lithium-ion battery or a lead-acid battery. It forms a closed circuit with the vibration energy collector 6 to store the recovered electrical energy.

[0048] Specifically, when the mechanical vibrations generated by the operation of the internal combustion engine module 2 are transmitted to the support 406 via the support member 408, the vibration energy harvester 6 converts the vibration energy into electrical energy through the piezoelectric effect or electromagnetic induction principle. This electrical energy is transmitted via wires to the battery in the semiconductor refrigeration plate 404 for storage. When the semiconductor refrigeration system is activated, the stored electrical energy can be directly used to perform cooling operations. Because the vibration energy harvester 6 is directly in contact with the vibration source and is arranged on the mechanical conduction path, it can effectively capture high-frequency vibration energy, avoiding energy loss during the transmission process.

[0049] Through the above-described technical solution, the present application achieves the recycling of vibration energy during the operation of the internal combustion engine module 2, converting the energy originally dissipated by the vibration damping component into effective electrical energy, thereby reducing the external power supply requirements of the semiconductor refrigeration system. Furthermore, because the energy recovery process is matched in real time with the power supply requirements of the semiconductor refrigeration system, the number of battery charge and discharge cycles is reduced, thereby extending the service life of the energy storage device.

[0050] According to the generator provided by the embodiment of the present invention, Figure 12 and Figure 13 As shown, the polygonal independent chamber 304 is a regular hexagonal independent chamber.

[0051] In this embodiment, the regular hexagonal independent chambers can be implemented using a honeycomb arrangement, with each chamber having a side length of 5 mm to 20 mm. This structure forms a uniformly distributed communication path of pores 305 through geometric symmetry, and utilizes the angle characteristics between adjacent sides of the regular hexagon to guide the sound waves to multiple reflections. The pores 305 can be implemented as circular channels with a diameter of 0.5 mm to 2 mm, with the channel spacing set to 3 to 5 times the aperture diameter. By controlling the channel density, a gradient acoustic impedance layer is formed.

[0052] Specifically, the regular hexagonal chambers form a honeycomb matrix arrangement in the first gap 302 between the shell 3 and the outer wall 301 of the internal combustion engine. When the sound wave enters the sound insulation interlayer 303, multiple reflection paths are generated in the network formed by the regular hexagonal chambers: the sound wave first enters a single chamber through the pores 305, and after being reflected more than three times between the hexagonal walls, it continues to propagate through the pores 305 of the adjacent chamber. In this process, the energy of the sound wave is gradually consumed, wherein the high-frequency sound waves produce interference cancellation when reflected on the wall, and the medium-frequency sound waves form energy attenuation due to the phase difference between the pores 305. The 120° internal angle design of the regular hexagon makes the sound wave reflection angle change regularly, which can reduce the possibility of straight-line penetration of the sound wave compared to the quadrilateral or pentagonal structure. At the same time, the triangular support structure formed by the honeycomb arrangement enhances the overall stiffness of the interlayer and avoids the degradation of acoustic performance caused by cavity deformation.

[0053] The hexagonal chambers achieve a high fill rate through seamless splicing, increasing the effective sound absorption area within the same space. Compared to randomly arranged polygonal structures, the periodic arrangement of regular hexagons forms a regular acoustic resonance system, achieving active noise reduction in the target frequency band by setting specific chamber dimensions.

[0054] Through the above-mentioned technical solution, this application effectively improves the efficiency of sound energy attenuation, covering the frequency band that primarily generates noise from the piston movement of internal combustion engines. The honeycomb structure maintains stable sound insulation performance while keeping the thickness of the sound-insulating interlayer 303 within 15 cm, thus resolving the issue of excessive bulk in traditional multi-layer sound-absorbing structures. Furthermore, the mechanical support structure formed by the regular hexagonal chambers enables the sound-insulating interlayer 303 to withstand the periodic pressure fluctuations of 0.5 MPa to 2 MPa generated by diesel engine operation, thus preventing noise reduction performance degradation due to structural deformation.

[0055] According to the embodiment of the present invention, a generator set is provided, such as Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As shown, it includes multiple generators mentioned in the above embodiments and also includes a frame 7; The liquid storage tank 403 is mounted on the support 406 and is located below the internal combustion engine module 2. The bottom surface of the support 406 communicates with the bottom surface of the liquid storage tank 403 to form a second liquid inlet 701, at which a second solenoid water valve 7011 is located. A third liquid inlet 702 is defined on the upper surface of the chassis 7, at which a third solenoid water valve 7021 is located. The third liquid inlet 702 is connected to the external cooling liquid pipe 707. The support 406 defines a second liquid outlet 703 and is provided with a fourth solenoid water valve 7031. The upper surface of the chassis 7 defines a third liquid outlet 706 and is provided with a fifth solenoid water valve 7061. The upper surface of the frame 7 defines a plurality of positioning holes 704, and the lower surface of the support 406 is provided with a plurality of positioning pins 705. When the positioning holes 704 and the positioning pins 705 engage, the second liquid inlet 701 aligns with the third liquid inlet 702, and the second liquid outlet 703 aligns with the third liquid outlet 706. The second liquid outlet 703 communicates with the liquid outlet of the heat absorption tube assembly 5. A sixth solenoid water valve 504 is provided between the liquid outlet of the heat absorption tube assembly 5 and the liquid inlet of the heat exchange tube 4022.

[0056] In this embodiment, the frame 7 is used to carry multiple generators to realize an integrated layout of multiple units; the second liquid inlet 701 is used to receive the cooling medium from the external condensing tower 708; the second electromagnetic water valve 7011 is used to switch the internal circulation or external circulation mode of the generator; the positioning hole 704 and the positioning pin 705 are used to ensure that the cooling pipe interface is automatically aligned when multiple units are installed; the third liquid outlet 706 is used to discharge the coolant circulating inside the unit to the external condensing tower 708; the sixth electromagnetic water valve 504 is used to adjust the flow path of the coolant in the internal circulation.

[0057] Specifically, the rack 7 serves as an integral support structure for multiple generator units. The liquid reservoir 403 is positioned beneath the internal combustion engine module 2, utilizing gravity to optimize coolant flow. The coordinated design of the positioning holes 704 and the positioning pins 705 allows the support 406 to automatically align with the liquid inlet and outlet on the rack 7 during installation, ensuring rapid assembly of multiple units. The second and third solenoid valves 7011 and 7021 control the flow of coolant into the external condenser tower 708. The fourth and fifth solenoid valves 7031 and 7061 manage the internal coolant discharge path. The sixth solenoid valve 504 independently regulates the connection between the heat absorption pipe and the heat exchange pipe 4022. When multiple units need to cooperate in heat dissipation, the second solenoid water valve 7011 and the third solenoid water valve 7021 are opened to allow the external coolant to enter the liquid storage tank 403 through the external circulation cold liquid pipe 707, and at the same time, the sixth solenoid water valve 504 is closed to block the internal circulation; when a single unit is running independently, the second solenoid water valve 7011 and the third solenoid water valve 7021 are closed and the sixth solenoid water valve 504 is opened, so that the coolant forms a closed loop between the heat absorption pipe and the heat exchange pipe 4022.

[0058] The integrated design of the rack (7 units) and the positioning structure enable fast and precise assembly of multiple units. The layered control strategy of six solenoid water valves allows the cooling system to flexibly switch between internal and external circulation modes. The linkage between mechanical positioning and solenoid valves prevents liquid leakage when multiple units are connected in parallel, while also reducing the complexity of manual operation.

[0059] Through the above-mentioned technical solution, this application solves the challenges of integrated heat dissipation and noise reduction for multiple generator sets, achieving efficient circulation control and modular rapid assembly of the cooling system. The positioning structure ensures automatic alignment of the cooling pipe interfaces of multiple units, the electromagnetic water valve assembly enables flexible switching between internal and external circulation modes, and gravity-assisted flow optimizes coolant circulation efficiency. This solution significantly improves the stability of the coordinated operation of multiple units while reducing installation and maintenance costs.
