Abstract
Description
Technical Field
[0001] This invention relates to the field of generator set technology, and in particular to a fast-cooling, silent water-cooled exhaust device. Background Technology
[0002] With the development of modern industry and technology, generator sets are increasingly widely used, from commercial buildings and energy supply in remote areas to meeting temporary power needs. However, traditional generator sets generate high-temperature exhaust gases during operation, especially exhaust temperatures that can reach over 800 degrees Celsius. This high temperature not only damages the equipment itself and shortens its lifespan but also affects the surrounding environment and the normal operation of other precision instruments. Furthermore, as mentioned in the question, if the high-temperature exhaust gases pass directly through the soundproof enclosure without treatment, the temperature inside the enclosure will rise, requiring ventilation to cool it down, but doing so will compromise the ultra-quiet operation.
[0003] Traditional cooling methods, such as air cooling or wind-cooled systems, have significant limitations in handling the high-temperature exhaust gases produced by engines. These methods are typically accompanied by high noise levels and are inefficient in high-temperature environments, leading to unnecessary energy waste. Furthermore, due to the lack of an effective thermal management system, traditional generator sets release a large amount of heat during prolonged operation, which not only increases the ambient temperature but may also interfere with the stability and performance of nearby electronic equipment. Summary of the Invention

[0044] Combination Figures 1 to 9 As shown, a rapid cooling silent water-cooled exhaust device includes a housing 1, an exhaust pipe 2, and a cooling component 3.
[0045] A water inlet pipe 11 is provided on one side of the box body 1, and a water outlet pipe 12 is provided at the bottom of the box body 1; an exhaust pipe 2 is located in the inner cavity of the box body 1 and extends to the outside of the box body 1; a cooling assembly 3 is located in the inner cavity of the box body 1 and is used to quickly cool the exhaust pipe 2.
[0046] The design incorporates a cooling system inside the enclosure, which effectively handles high-temperature exhaust gases exceeding 800 degrees Celsius within a fully enclosed space. This cooling system rapidly cools the exhaust gases to a safe level, ensuring the equipment operates in an ultra-quiet manner. This design meets the energy conservation and emission reduction requirements of modern industry, not only improving energy efficiency but also reducing pollutant emissions and promoting sustainable development goals, while also ensuring the product achieves an ultra-quiet operation. Specific Implementation Example 1:
[0048] The inner cavity of the housing 1 has a first chamber 13, a second chamber 14, and a third chamber 15 arranged from top to bottom on one side. A first water passage 16 communicating with the second chamber 14 is located on the lower side of the first chamber 13, and a second water passage 17 communicating with the third chamber 15 is located on the lower side of the second chamber 14. A water inlet pipe 11 is provided on one side of the first chamber 13, and a water outlet pipe 12 is provided on the lower side of the third chamber 15. An exhaust pipe 2 is located inside the second chamber 14, with its output end passing through the housing 1 and extending to the outside of the housing 1. The lower part of the exhaust pipe 2 has multiple input ends along its length, each input end being connected to an exhaust manifold 21. The input end of the exhaust manifold 21 passes through the third chamber 15 and extends to the outside of the housing 1.
[0049] In this system, gas is introduced into exhaust pipe 2 through exhaust manifold 21 and finally discharged to the outside of housing 1 from the output end of exhaust pipe 2. During the process of the gas passing through exhaust manifold 21 and exhaust pipe 2, a large amount of heat is generated. If the gas is not cooled, its temperature can reach over 800 degrees Celsius, thus generating noise. Therefore, a first chamber 13, a second chamber 14, and a third chamber 15 are arranged vertically inside housing 1. These three chambers form a series water-cooling channel. The inlet pipe 11 connects to the first chamber 13, while the outlet pipe 12 is located on the lower side of the third chamber 15. To ensure smooth water flow throughout the cooling path, a first water passage 16 is provided between the first chamber 13 and the second chamber 14, and a second water passage 17 is provided between the second chamber 14 and the third chamber 15. When cooling water enters the first chamber 13 through the inlet pipe 11, it absorbs some of the heat transferred from exhaust pipe 2. As the temperature rises, hot water flows into the second chamber 14 through the first water passage 16, continuing to absorb more heat. Then, the hot water passes through the second water passage 17 to the third chamber 15, and finally exits from the outlet pipe 12, carrying away most of the heat from the exhaust gas. This process not only effectively reduces the temperature of the exhaust gas but also reduces the thermal stress changes caused by the temperature difference, thereby reducing the noise generated during equipment operation and achieving a good quiet operation.
[0050] To further explain, the exhaust manifold 21 is set at an angle. The angle of the exhaust manifold 21 is 45°.
[0051] The 45° inclined angle of the exhaust manifold 21 has several important functions and advantages:
[0052] 1. Optimized airflow path: The 45° tilt design helps optimize the flow path of exhaust gas from the engine cylinders to the exhaust pipe 2. This angle reduces gas resistance at bends, allowing exhaust gas to be discharged more smoothly, thereby improving the efficiency of the entire exhaust system.
[0053] 2. Reduce back pressure: A proper tilt angle helps reduce back pressure in the exhaust system. Excessive back pressure can affect engine performance, increase fuel consumption, and potentially cause emissions problems. By designing the exhaust manifold at a 45° angle, the impact on engine output power can be minimized while ensuring effective exhaust.
[0054] 3. Thermal Management: The angled exhaust manifold helps improve heat distribution, allowing heat to be transferred more evenly to the cooling system or surrounding air, preventing localized overheating. This is crucial for protecting exhaust system materials and extending their service life.
[0055] 4. Noise control: The tilted design can also help change the direction of sound wave propagation, which helps to disperse or reflect some noise. Combined with the water cooling measures inside the cabinet, it further enhances the overall quietness effect.
[0056] Combination Figure 4 As shown, a muffler 22 is installed inside the exhaust pipe 2. The muffler attenuates high-frequency and low-frequency noise generated during exhaust by altering the exhaust gas flow path, increasing the sound wave reflecting surface, or using sound-absorbing materials. It absorbs or weakens sound wave energy, thereby significantly reducing the amount of noise emitted from the exhaust pipe terminal. Some high-performance mufflers even employ special structures (such as perforated plates, resonant cavities, etc.) to provide better noise reduction without sacrificing performance. In some cases, the design of the muffler can also help disperse heat and prevent localized overheating. This helps protect exhaust system components from high-temperature damage and contributes to the thermal balance of the entire exhaust system. Specific Implementation Example 2:
[0058] Combination Figure 5 and Figure 6As shown, the cooling assembly 3 includes a serpentine tube 31 and an acceleration assembly 32. The serpentine tube 31 is wound around the exhaust pipe 2. The inlet end of the serpentine tube 31 is connected to the first water passage 16, and the outlet end of the serpentine tube 31 is connected to the second water passage 17. The acceleration assembly 32 is respectively disposed at the first water passage 16 and the second water passage 17. The acceleration assembly 32 includes a mounting bracket 321, a rotating shaft 322, a limiting plate 323, and spiral blades 324. The rotating shaft 322 is rotatably mounted on the mounting bracket 321. The top end of the rotating shaft 322 passes through the mounting bracket 321 and extends to the upper part of the mounting bracket 321 where the limiting plate 323 is disposed. Multiple spiral blades 324 are disposed on the rotating shaft 322.
[0059] The serpentine tube 31 surrounds the exhaust pipe 2, ensuring maximum heat exchange between the cooling water and the high-temperature outer wall of the exhaust pipe. This layout allows the cooling water to directly absorb heat from the exhaust pipe, effectively reducing the exhaust temperature. The serpentine tube design increases the water path length, providing more heat exchange opportunities within a limited space. After entering the serpentine tube through the first water passage 16, the cooling water flows along a meandering path until it reaches the second water passage 17. During this process, the cooling water continuously absorbs heat, effectively cooling the exhaust. When the cooling water passes through the first water passage 16, the water flow impacts the spiral vanes 324, driving the rotating shaft 322 to rotate. As the rotating shaft rotates, the spiral vanes further agitate and accelerate the water flow, enhancing the water's dynamics and making the flow more turbulent, thus improving heat transfer efficiency. Due to the presence of the acceleration component, the cooling water not only flows faster but also forms a more complex turbulent state, which greatly increases the heat exchange efficiency between the cooling water and the exhaust pipe surface. Compared to traditional static water flow, turbulent flow allows for more thorough mixing of water molecules and a faster reduction in the temperature difference between hot and cold water, resulting in a faster and more uniform cooling effect. Since the first chamber 13 and the third chamber 15 are filled with water, even noise generated by the high temperature of exhaust gas from the exhaust pipe 2 is absorbed by the vibration ripples produced by the water within the first chamber 13 and the third chamber 15.
[0060] Specifically, when high-temperature exhaust gas passes through exhaust pipe 2, it generates mechanical vibrations and sound waves. These sound waves propagate along the exhaust pipe and may reach the first chamber 13 and the third chamber 15, which they come into contact with. Since these two chambers are filled with water, the sound waves entering the water cause surface vibrations, forming ripples. These ripples are essentially a form of energy dissipation for the sound waves. Each time a ripple forms and spreads on the water surface, it carries away a portion of the sound energy, converting it into heat or kinetic energy, thus effectively reducing the energy of the original sound waves. Water is an excellent medium for sound wave propagation, but it is also a good absorber of sound energy. Compared to air, sound travels faster in water, but it also attenuates rapidly due to friction between water molecules. Therefore, even if some sound waves manage to penetrate the water surface, they are quickly absorbed by the water and converted into heat or other forms of energy, making further propagation difficult. Within the water-filled chambers, sound waves reflect multiple times between the upper and lower surfaces of the water, producing complex interference phenomena. This multiple reflection and interference further disperses the sound wave energy, making the sound energy in any single direction very weak, ultimately achieving a significant noise reduction effect. Specific Implementation Example 3:
[0062] Combination Figure 7 As shown, the cooling assembly 3 also includes a spiral tube 33, which is wound around the exhaust pipe 2. The inlet end of the spiral tube 33 is connected to the first water passage 16, and the outlet end of the spiral tube 33 is connected to the second water passage 17. The spiral tube 33 has multiple protrusions 34 inside.
[0063] The spiral tube design significantly extends the flow path of cooling water within a limited space. Compared to straight pipes, this meandering path increases the contact time and area between the cooling water and the outer wall of the exhaust pipe, thereby improving heat exchange efficiency. The spiral tube is tightly wound around the exhaust pipe 2, ensuring maximum contact area between them. This allows for more direct absorption of heat from the exhaust pipe, achieving efficient heat transfer. The multiple protrusions 34 inside the spiral tube are a key design feature. These protrusions break the laminar flow of the cooling water, forcing the flow into turbulence. In turbulent flow, the mixing between water molecules is more intense, and the temperature difference between hot and cold water decreases rapidly, thus accelerating the transfer of heat from high-temperature to low-temperature regions. Turbulence not only increases water mixing but also enhances boundary layer disturbance, reducing thermal resistance. This means that more heat can be carried away by the cooling water instead of remaining on the side near the exhaust pipe, further improving cooling efficiency. As previously mentioned, the rotating shaft 322 and spiral blades 324 in the acceleration assembly 32 already play a role in accelerating the water flow. When water enters the spiral tube 33, its internal structure (i.e., the protrusions) further enhances the water's velocity and turbulence, creating a highly efficient cooling cycle. Combined with these factors, the spiral tube 33 and its internal protrusions 34 work together to significantly improve the overall performance of the cooling system. As the cooling water passes through the spiral tube, it continuously absorbs heat, and due to the turbulence, heat transfer is more rapid and uniform, ultimately achieving rapid cooling of the high-temperature exhaust gas in the exhaust pipe 2. This highly efficient cooling method not only quickly reduces the initial high temperature but also maintains the exhaust system within a relatively stable, lower temperature range, which is crucial for protecting the engine and other related components from high-temperature damage. Specific Implementation Example 4:
[0065] Combination Figure 9 As shown, the cooling assembly 3 also includes a Tesla valve port 35 opened in the second chamber 14, and the exhaust pipe 2 is located in the Tesla valve port 35.
[0066] The Tesla valve orifice 35 incorporates an innovative cooling mechanism that not only enhances cooling performance but also improves overall system efficiency. The Tesla valve is a valveless, unidirectional flow device inspired by Nikola Tesla's patented inventions. When applied to cooling component 3, the Tesla valve orifice 35 achieves rapid cooling through several mechanisms:
[0067] 1. Optimize fluid dynamics
[0068] Reduced turbulence losses: The unique geometry of the Tesla valve orifice 35 reduces turbulence losses as cooling water passes through. This structure guides the water flow in a smoother, more efficient manner, thereby reducing energy consumption and ensuring that more energy is used for heat exchange rather than overcoming internal friction.
[0069] Increased flow rate: Due to the special design of the Tesla valve orifice, it can significantly increase the flow rate without increasing additional pressure. This allows the cooling water to complete a full cycle in a shorter time, removing heat more quickly and achieving more efficient cooling.
[0070] 2. Enhance heat transfer efficiency
[0071] Uniform heat distribution: An optimized flow channel is formed around the exhaust pipe 2 within the Tesla valve orifice 35, ensuring that the cooling water can evenly surround and contact the outer wall of the exhaust pipe. This layout helps to evenly distribute heat throughout the coolant, preventing localized overheating.
[0072] Extended heat exchange time: Despite the increased flow rate, the Tesla valve orifice design allows the water to remain within a specific area for a sufficient amount of time to fully absorb heat from the exhaust pipe. This balance ensures effective heat exchange even at high flow rates.
[0073] 3. Utilizing laminar flow effect
[0074] Laminar Flow and Boundary Layer Control: The design of the Tesla valve orifice helps maintain laminar flow, especially in critical areas near the exhaust pipe surface. In laminar flow, the relative movement between cooling water molecules is minimal, which helps form a stable boundary layer and further improves heat transfer efficiency.
[0075] Reduced backflow and eddies: Backflow and eddies, which are common in traditional pipes, can lead to a decrease in heat exchange efficiency. The Tesla valve orifice design effectively suppresses these adverse phenomena, making the cooling process smoother and more efficient.
[0076] 4. Overall cooling effect
[0077] Rapid response to temperature changes: Thanks to the optimized design described above, the Tesla valve orifice 35 can quickly respond to changes in exhaust temperature, adjusting the flow characteristics of the coolant in a timely manner to ensure optimal cooling at all times. This rapid response capability is crucial for dealing with frequent temperature fluctuations during engine operation.
[0078] Reduced system noise: In addition to efficient cooling, the Tesla valve orifice design can also reduce mechanical noise caused by water flow impact or turbulence, providing a quieter operating environment for the entire system.
[0079] It is important to note that the housing 1 is equipped with an overflow pipe 18, which plays a crucial role in the cooling system, mainly in the following aspects:
[0080] 1. Preventing overpressure: During operation, the water inside the cooling system may expand due to thermal expansion and contraction, causing the system pressure to rise. The overflow pipe provides a safe outlet for this excess water, preventing damage to the housing or other components due to excessive pressure.
[0081] 2. Maintaining a stable liquid level: As cooling water circulates, the liquid level may drop due to evaporation, leakage, or other reasons. An overflow pipe helps monitor and maintain an appropriate water level, ensuring the cooling system always has sufficient cooling medium to perform its functions.
[0082] 3. Remove air: When the cooling system is first filled or refilled after maintenance, air may get into the system. If these air bubbles are not removed in time, they will affect cooling efficiency and may cause localized overheating. The overflow pipe can act as an vent to help remove air from the system and ensure effective cooling.
[0083] 4. Equipment protection: By installing an overflow pipe, some hot water can be automatically released when the cooling water temperature is too high or when the system malfunctions, in order to protect the safe operation of the entire system and avoid damage to the equipment caused by high temperature.
[0084] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
