Description

Technical Field

[0001] This application relates to the technical field of engineering machinery, and more particularly to a containerized generator set. Background Technology

[0002] Containerized generator sets need to meet the demands of high-power applications and withstand high-temperature operating environments. During operation, these devices must ensure sufficient airflow for effective heat dissipation, achieve good noise reduction, and be easy to transport.

[0003] Currently, containerized generator sets typically house a high-powered engine inside the container, with the water tank also located within the container, and the muffler positioned on the top of the container. However, a single high-powered engine is expensive and consumes a lot of fuel. Furthermore, the intake air for the water tank passes through the engine and generator, which generate heat radiation, before reaching the water tank, causing the intake air to be heated and affecting the water tank's heat dissipation efficiency. In addition, placing the muffler on the top of the container provides limited noise reduction, and it usually needs to be removed for transportation, which is also unfavorable for sea transport.

[0004] Therefore, there is an urgent need for a containerized generator set that can simultaneously meet the requirements of high power output, adaptability to high-temperature environments, excellent noise reduction, and compact structure. Utility Model Content

[0005] This application provides a containerized generator set that simultaneously meets the requirements of high power use, adaptability to high temperature environments, excellent noise reduction, and compact structure.

[0011] In one possible implementation, a second air inlet is provided on the side wall of the housing, which communicates with the second chamber.

[0027] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0029] In existing technologies, containerized generator sets typically employ a single high-power engine to meet high power demands, but this results in high manufacturing costs and high fuel consumption. When the water tank is placed inside the container, its air intake path must pass through the engine area, causing the intake air to be heated and affecting heat dissipation efficiency. Furthermore, while externally mounted mufflers on the top of the container can reduce some noise, the noise reduction effect is limited, and they need to be disassembled for transport, which is not conducive to overall transportation in maritime scenarios. In high-temperature environments, existing structures struggle to balance the air intake required for high-power operation with the demands for heat dissipation and noise reduction.

[0030] Therefore, this application avoids cooling air flowing through high-temperature areas by placing the water tank and engine in two separate chambers of the housing.

[0031] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings. (For ease of description, the X direction is defined as the first direction, and the Y direction as the second direction.)

[0032] Reference Figure 1 , Figure 2 , Figure 3 This application discloses a containerized generator set, including a container 1, an engine 2 and a water tank 3. The container 1 has a first air inlet 13. The engine 2 is located inside the container 1. The water tank 3 is located inside the container 1 and is located on the side close to the first air inlet 13.

[0033] The container 1 is the outer shell of a shipping container, used to house the generator set components and form an independent space. The first air inlet 13 is an opening on the side wall or end of the container 1 to introduce outside air. The water tank 3 is a heat exchange device for cooling the circulating fluid of the engine 2, and its position close to the first air inlet 13 allows cold air to preferentially flow over the heat dissipation surface.

[0034] Specifically, after external air enters the housing 1 through the first air inlet 13, it first flows through the water tank 3 area near the air inlet. At this point, the air temperature has not yet been affected by the heat radiation from the engine 2, effectively carrying away the heat inside the water tank 3. After heat exchange, the air continues to flow to the exhaust port 15 for discharge. The internal space of the housing 1 is divided into different functional areas. The layout of the water tank 3 and the engine 2 forms a directional airflow channel, preventing hot air from flowing back to the air inlet side of the water tank 3 and ensuring that the heat dissipation efficiency is not affected by the heat radiation from the engine 2. The enclosed housing 1 structure can be hoisted as a whole during transportation without disassembling internal components.

[0035] This application further proposes that the housing 1 is provided with a partition plate 4 along the first direction, the partition plate 4 is used to divide the interior of the housing 1 into a first chamber 11 and a second chamber 12 along the second direction, the water tank 3 is provided in the first chamber 11, the engine 2 is provided in the second chamber 12, and the first air inlet 13 communicates with the first chamber 11.

[0036] The partition 4 is a partition structure set along the length of the housing 1, which can be made of metal plate, and is used to physically isolate different functional areas to reduce heat transfer and noise propagation. The first chamber 11 is a semi-enclosed area near the first air inlet 13, used to centrally arrange the water tank 3 and directly introduce external cold air. The second chamber 12 is an independent space adjacent to the first chamber 11, used to accommodate the engine 2 and limit its heat radiation range.

[0037] Specifically, the partition plate 4 is installed along the length of the housing 1, dividing the interior of the housing 1 into a first chamber 11 near the first air inlet 13 and a second chamber 12 away from the air inlet. The water tank 3 is located in the first chamber 11, directly receiving cold air from the first air inlet 13, preventing the heat generated by the engine 2 during operation from affecting the heat dissipation efficiency of the water tank 3 through air convection or radiation. The engine 2 is located in the second chamber 12, and the partition plate 4 blocks its operating noise from being transmitted to the first chamber 11. At the same time, it prevents rainwater from flowing from the first chamber 11 to the second chamber 12. The first air inlet 13 is directly connected to the first chamber 11, and cold air preferentially enters the water tank 3 area, forming an independent heat dissipation path.

[0038] Compared to related technologies, where the water tank 3 and engine 2 share the same chamber, the heat generated by the engine 2 heats the air flowing through the water tank 3, leading to decreased heat dissipation efficiency. This application separates the water tank 3 and engine 2 into independent chambers using a partition plate 4. Cool air enters the area containing the water tank 3 directly, avoiding the influence of heat radiation from the engine 2. Simultaneously, the partition plate 4 blocks the noise propagation path, eliminating the need for an external muffler 8 to reduce noise. Furthermore, the dual-chamber structure allows for a more compact equipment layout, facilitating overall transportation.

[0039] Through the above technical solution, this application solves the problem of heat dissipation efficiency of water tank 3 being affected by thermal interference from engine 2, while optimizing equipment layout space and reducing transportation restrictions. The independent chamber formed by partition plate 4 effectively isolates noise and heat transfer paths, meeting maritime transport requirements without additional disassembly of muffler 8, and supports the compact arrangement of multiple engines 2 to replace a single high-power device.

[0040] This application further proposes that a first electric drive fan 5 be installed at the second air inlet 14.

[0041] The first electric drive fan 5 is an axial or centrifugal ventilation device driven by electricity. Specifically, it can be implemented by using a variable frequency speed control motor in conjunction with a blade assembly to actively enhance the airflow speed of the second air inlet 14 and adjust the air volume.

[0042] Specifically, the first electric drive fan 5 is integrated and installed inside the housing 1 at the second air inlet 14. When the engine 2 is running, the first electric drive fan 5 forces outside air into the second chamber 12 of the housing 1, and removes the heat dissipated by the engine 2 through forced convection. At the same time, the active air supply mode of the electric drive fan can overcome the flow limitations of natural ventilation, ensuring that a stable air intake volume can be maintained even in high-temperature environments.

[0043] Compared to related technologies, traditional container generator sets rely on natural convection for air intake. When the outside temperature is too high or the heat radiation from the engine 2 increases, insufficient air intake leads to a decrease in the cooling efficiency of the water tank 3. This application actively controls the air intake through an electric fan, which can maintain sufficient cooling airflow under high-temperature conditions and avoid noise leakage caused by excessive air intake.

[0044] Through the above technical solution, this application achieves active control of the intake airflow, solving the problem of insufficient natural airflow leading to reduced heat dissipation efficiency of the water tank 3 under high-temperature environments. Simultaneously, the enclosed installation method of the electric drive fan avoids the transportation limitations imposed by traditional external silencers 8, keeping the overall structure compact and allowing for transportation without disassembly.

[0045] This application further proposes that a second air inlet 14 is provided on the side wall of the housing 1, which communicates with the second chamber 12.

[0046] The second air inlet 14 is an opening structure located on the side wall of the housing 1, used to introduce external air into the second chamber 12.

[0047] Specifically, the second air inlet 14 directly connects the side wall of the housing 1 to the second chamber 12. External air is introduced into the second chamber 12 through the second air inlet 14 and discharged through the exhaust port 15, forming a directional airflow. This airflow path is independent of the cooling airflow of the water tank 3 in the first chamber 11. The first chamber 11 is both the area of ​​the water tank 3 and the area where all hot air gathers. The air heated by the engine 2 gathers here and is discharged from the exhaust port 15.

[0048] Compared to related technologies, existing containerized generator sets rely on only a single air inlet, causing the air intake in the engine 2 area to flow through high-temperature components. The increased air temperature before entering the water tank 3 area negatively impacts heat dissipation efficiency. This application addresses this by adding an independent air inlet to the side wall of the second chamber 12, completely isolating the airflow from the engine 2 to the water tank 3. Simultaneously, the first electric drive fan 5 actively controls the airflow to prevent cross-contamination of hot air.

[0049] Through the above technical solution, this application achieves independent air intake cooling for the chamber where the engine 2 is located, effectively reducing the air temperature entering the water tank 3 area and ensuring that the water tank 3 maintains stable heat dissipation performance under high-temperature environments. The active air supply function of the second electric drive fan 5 can dynamically adjust the air intake volume according to the load of the engine 2 to adapt to different operating conditions. The layout of the second air intake 14 on the side wall of the housing 1 does not occupy the top space, which facilitates the compact design of the overall structure to meet transportation requirements.

[0050] This application further proposes that the partition plate 4 has a ventilation opening that communicates with the first chamber 11 and the second chamber 12; and / or, a second electric fan 6 is provided on the ventilation opening.

[0051] The vent is an airflow channel that penetrates the partition plate 4, and can be implemented using a rectangular perforation array to promote air circulation between the first chamber 11 and the second chamber 12. The second electric fan 6 is an active air supply device installed on the partition plate 4 at the vent, and can be implemented using an axial flow fan to accelerate the airflow speed between the chambers.

[0052] Specifically, when the heat generated by the engine 2 during operation in the second chamber 12 dissipates to the first chamber 11 through the vent, the second electric fan 6 draws the hot air from the second chamber 12 into the first chamber 11. Once in the first chamber 11, the air is then drawn away from the exhaust vent by the third electric fan 7. Simultaneously, the cooling airflow from the water tank 3 in the first chamber 11 can naturally convection through the vent to the second chamber 12, forming a continuous cooling path through both chambers. When the second electric fan 6 is turned off, the vent can still provide basic cooling through natural convection.

[0053] Compared with related technologies, traditional container generator sets do not have through-type ventilation openings on the partition structure, which makes it impossible to effectively transfer the heat from engine compartment 2 to water tank area 3. This application establishes a heat exchange channel through the through-type design of the ventilation opening, avoiding the heat dissipation redundancy or insufficiency caused by a single fixed structure.

[0054] Through the above technical solution, this application has optimized the air circulation path between the engine compartment 2 and the water tank 3 area. While maintaining the compactness of the internal space of the housing 1, it effectively reduces the impact of the engine 2 operation on the intake air temperature of the water tank 3. At the same time, it improves the heat dissipation efficiency by combining active air supply and passive convection, and solves the technical problem of blocked airflow path in high temperature environment.

[0055] This application further proposes that the top of the housing 1 is provided with an exhaust vent 15 that communicates with the first chamber 11; and / or, a third electric drive fan 7 is provided on the exhaust vent 15.

[0056] The exhaust vent 15 is an opening structure located at the top of the housing 1. It can be implemented using rectangular or circular holes in conjunction with a guide shroud, and is used to directionally exhaust hot air from the first chamber 11. The third electric drive fan 7 is an axial flow fan installed at the exhaust vent 15 in the housing 1. Specifically, it can be implemented using a variable frequency speed control motor to drive the fan blades to rotate, and is used to actively accelerate the exhaust speed of hot air.

[0057] Specifically, the hot air in the first chamber 11 rises to the top of the housing 1 under natural convection. The exhaust vent 15 is directly connected to the first chamber 11 to form a hot airflow channel. The third electric fan 7 starts and creates a negative pressure area, accelerating the hot air to be discharged outward through the exhaust vent 15. The exhaust vent 15 is located at the highest point of the top of the housing 1, utilizing the rising characteristics of hot air to achieve unpowered natural ventilation.

[0058] Compared to related technologies, traditional container generator sets rely solely on natural convection for heat dissipation, and their exhaust efficiency is significantly affected by ambient temperature. This application creates a directional airflow path through the top exhaust vent 15, and in conjunction with an optional active exhaust device, forces hot air out under high-temperature conditions, preventing the water tank 3 from experiencing a decrease in heat dissipation efficiency due to excessively high temperatures within the first chamber 11.

[0059] Through the above technical solution, this application effectively solves the problem of heat accumulation in a sealed container, ensuring that the engine 2 operates stably in a high-temperature environment. The combined design of the exhaust vent 15 and the third electric drive fan 7 retains the low energy consumption characteristics of the natural exhaust mode, while enhancing the heat dissipation capacity through active exhaust, avoiding transportation restrictions caused by removing the muffler 8 or adding an external heat dissipation device.

[0060] This application further proposes that a silencer 8 is installed in the second chamber 12.

[0061] The muffler 8 is a device used to reduce the operating noise of the engine 2. Specifically, it can be achieved by combining porous sound-absorbing materials with an expansion chamber structure, and noise reduction is achieved through the reflection and absorption of sound waves in the cavity.

[0062] Specifically, the muffler 8 is integrated into the top of the second chamber 12 inside the housing 1. When the noise generated by the engine 2 is transmitted to the second chamber 12, the muffler 8 attenuates the sound waves through its internal multi-layer sound-absorbing structure.

[0063] Compared with related technologies, the traditional solution installs the muffler 8 on the top of the enclosure 1, which limits the noise reduction effect due to the external space of the enclosure 1, and the muffler 8 needs to be removed during transportation. This application integrates the muffler 8 into the second chamber 12, which shortens the noise transmission path and makes the overall structure meet the transportation size requirements.

[0064] Through the above technical solution, this application achieves effective attenuation of engine 2 operating noise inside housing 1, avoiding the problem of reduced assembly efficiency of external muffler 8 due to transportation and disassembly.

[0065] This application further proposes that two sets of engines 2 are arranged side by side along the second direction in the second chamber 12, and the two sets of engines 2 are respectively located on both sides of the vent along the first direction.

[0066] Among them, the two sets of engines 2 refer to two independently operating power units, which can be implemented by using diesel engines 2 with the same or different power. By arranging them in parallel, the load on a single unit is reduced and the redundancy is increased.

[0067] Specifically, the second chamber 12 is divided into independent areas by the partition plate 4 along the length of the housing 1, and the two sets of engines 2 are symmetrically arranged on both sides of the ventilation opening along the width direction.

[0068] Compared with related technologies, the traditional solution uses a single high-power engine 2, resulting in high cost and an unreasonable heat dissipation path. This application replaces a single high-power device by arranging two sets of engines 2 in parallel, which reduces the purchase cost and utilizes the symmetrical layout on both sides of the ventilation port to form a diversion heat dissipation channel, avoiding the disorderly diffusion of high-temperature airflow within the housing 1. In addition, the spatial isolation design between the engine 2 and the water tank 3 area further blocks the heat radiation transfer path.

[0069] Through the above technical solutions, this application realizes the coordinated operation of dual engines 2 to replace a single high-power device, effectively reducing equipment procurement costs and operating fuel consumption; the symmetrical layout on both sides of the ventilation port optimizes the heat dissipation airflow distribution, avoiding the heat of engine 2 from affecting the heat dissipation efficiency of water tank 3; at the same time, the compact structural design meets the transportation size restrictions, and the equipment can be packed for sea freight without disassembly.

[0070] This application further proposes that there are two water tanks 3 arranged along the first direction, and the two water tanks 3 are respectively connected to the two sets of engines 2 in a one-to-one correspondence.

[0071] The two water tanks 3 refer to two independently installed heat dissipation units, which can be metal heat dissipation boxes 1 arranged in parallel. Each water tank 3 is connected to the corresponding engine 2 cooling system to achieve independent heat dissipation. The one-to-one connection means that each water tank 3 is individually connected to the corresponding engine 2 cooling circuit through a pipeline, which can be a flange interface or a flexible hose connection, to ensure the independent operation of the cooling system.

[0072] Specifically, the housing 1 is internally divided into a first chamber 11 and a second chamber 12. Two sets of engines 2 are arranged side-by-side along a second direction within the second chamber 12, with each set located on either side of a vent along a first direction. Two water tanks 3 are positioned along the first direction within the second chamber 12, each connected to its corresponding engine 2 via an independent cooling pipe. Coolant exchanges heat through a circulation path between the water tanks 3 and the engines 2, preventing interference between the cooling systems of different engines 2.

[0073] Compared to related technologies, traditional solutions require a single high-power engine 2 to be matched with a single water tank 3, resulting in cooling efficiency being limited by hot air recirculation, and the high-power engine 2 is also costly. This application reduces the power requirement of a single engine 2 by independently connecting two sets of engines 2 to two water tanks 3, and avoids the impact of hot air on cooling efficiency through independent heat dissipation paths. Furthermore, the dual-engine 2 layout maintains the total power while making the equipment structure more compact and easier to transport.

[0074] Through the above technical solution, this application achieves modular matching between the cooling system and engine group 2, reducing equipment manufacturing costs, while improving cooling efficiency under high-temperature environments through independent heat dissipation paths. The corresponding layout of the dual water tanks 3 and dual engines 2 further optimizes the utilization rate of the internal space of the housing 1, and transportation requirements can be met without disassembling the muffler 8.

[0075] This application further proposes that the interior of the housing 1 is equipped with sound-absorbing cotton.

[0076] Among them, sound-absorbing cotton refers to a flexible material with sound-absorbing function, which can be made of glass fiber cotton, polyester fiber cotton or rock wool. It absorbs sound wave energy through its internal porous structure and reduces noise transmission. The sound-absorbing cotton can cover the inner wall surface of the box 1 or fill the cavity structure of the box 1, and achieve noise reduction by directly contacting the noise source or the sound wave propagation path.

[0077] Specifically, sound-absorbing cotton is placed on the inner wall surface of the housing 1 or filled into the internal cavity of the housing 1, covering areas including the area where the engine 2 is located, the area where the water tank 3 is located, or the area around the vents. When the noise generated by the engine 2 is running and travels through the air to the inner wall of the housing 1, the sound-absorbing cotton, through its porous structure, converts sound energy into heat energy, reducing sound wave reflection and transmission, thereby reducing external noise of the housing 1. At the same time, the sound-absorbing cotton forms an integrated layout with the internal structure of the housing 1, eliminating the need for external installation and avoiding the need for disassembly during transportation due to external components.

[0078] Compared to related technologies, which place the muffler 8 externally on the top of the housing 1, it can only attenuate noise in a specific frequency band, and the external structure needs to be disassembled before transportation, increasing operational complexity. In contrast, this application integrates the sound-absorbing cotton inside the housing 1, which can not only absorb the broadband noise generated by the engine 2, water tank 3 and ventilation airflow, but also maintain the structural integrity of the housing 1 and avoid disassembly.

[0079] Through the above technical solution, this application achieves effective suppression of noise inside the container, while ensuring the compactness of the container structure 1, meeting the requirements for the integrity of the equipment during maritime transport, and solving the problems of limited noise reduction effect and inconvenient transportation of external silencers 8.

[0080] In this application, the first direction is the width direction of the box 1, and the second direction is the width direction of the box 1.
