Description

Technical Field

[0001] This utility model belongs to the technical field of generator soundproof cover, and in particular relates to a protective cover for a dual-cycle high-efficiency cooling low-noise generator set. Background Technology

[0002] A generator soundproof enclosure is a specialized device used to reduce generator operating noise. Through sound-absorbing and sound-insulating materials and structural design (such as a metal casing, rock wool / glass wool sound-absorbing layer, and sound-insulating felt), it effectively reduces noise transmission by 20-40 dB(A) while also addressing heat dissipation needs (such as silencing ducts or forced ventilation systems). It is widely used in industrial, commercial, and residential settings where quiet operation is crucial, and it also provides dust and moisture protection, extending equipment lifespan. When selecting a generator enclosure, it is essential to match the generator power, environmental conditions (such as waterproofing and fire resistance), and compliance (meeting local noise standards). During installation, attention must be paid to vibration reduction and sealing, and ventilation and sound-absorbing materials should be regularly maintained to ensure performance.

[0003] Most generator soundproof enclosures use parallel fan cooling modules inside. While this can ensure uniform and efficient heat dissipation, the generator temperature does not increase instantaneously during actual use. Multiple fans would be redundant, and multiple fan modules are expensive and not conducive to sound insulation. This is especially true for larger generator soundproof enclosures, where more fan modules are required.

[0004] To address the aforementioned issues, this application proposes a dual-cycle high-efficiency cooling low-noise generator set protective cover. Utility Model Content

[0005] The purpose of this invention is to provide a dual-cycle, high-efficiency cooling, low-noise generator set protective cover, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a dual-cycle high-efficiency cooling low-noise generator set protective cover, comprising a main body, the main body including a soundproof cover with an internal sound insulation structure, air intake pipes symmetrically arranged at the ends of the soundproof cover for air intake, and exhaust pipes symmetrically arranged at the top of the soundproof cover for exhaust, a heat dissipation plate mounted on the upper part of the main body, both ends of the heat dissipation plate being connected to the exhaust pipes and cooperating with the soundproof cover to form an external circulation channel, which can carry away the heat inside the soundproof cover; an internal fan is provided on the upper part of the main body, and a guide shroud is installed on the upper end of the internal fan to guide the airflow, the internal fan and the guide shroud combined in the soundproof cover to form an internal circulation channel, the internal circulation channel can also transfer heat to the heat dissipation plate through the heat exchange plate and carry it outward through the external circulation channel.

[0008] Furthermore, the heat sink has uniformly distributed heat-conducting fins inside, and the heat sink has a guide groove that runs vertically through it. The path of the guide groove is wavy. A drive mechanism is provided between the body and the heat exchange plate to drive the flow guide and the inner fan to move along the path of the guide groove in the body. The heat exchange plate has a movable groove.

[0009] Furthermore, the air guide includes an air guide pipe fixed to the air outlet of the inner fan, with symmetrical first air pipes on both sides of the air guide pipe and symmetrical second air pipes at the lower ends of both sides of the air guide pipe. The first air pipes and the second air pipes are separated within the air guide pipe by a flow divider plate.

[0010] Furthermore, the first air pipe faces the inner side of the soundproof cover, the second air pipe faces the lower end of the side of the soundproof cover, and the air intake end of the inner fan is located directly below the two second air pipes.

[0011] Furthermore, the upper and lower surfaces of the heat exchange plate are in contact with the heat dissipation plate and the flow guide shroud, respectively, and are used for temperature conduction between the two.

[0012] Furthermore, the driving mechanism includes a lead screw symmetrically arranged and rotating in the soundproof cover, and an internal threaded sleeve fixed on both sides of the heat exchange plate and threadedly engaged with the lead screw. A slide rail is also provided between the heat exchange plate and the flow guide cover, which is perpendicular to the lead screw. A driving column is fixed at the upper end of the flow guide cover and slides in the movable groove and the guide groove.

[0013] Furthermore, the bottom of the air intake pipe is connected to the bottom of the inner side of the soundproof cover and the top is the air intake end. The air intake pipe is also provided with a number of first sound-absorbing sheets arranged in parallel.

[0014] Furthermore, the exhaust pipe is connected to the heat sink at both ends and has an external fan in the middle of its top surface that drives the airflow to circulate externally. The exhaust pipe is provided with several second sound-absorbing cottons arranged in parallel inside.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses a drive mechanism with guide grooves and movable grooves to move the inner fan at the upper inner side of the soundproof cover. The movable design ensures sufficient airflow within the soundproof cover. The guide shroud, in conjunction with the inner fan, circulates the air inside the soundproof cover, achieving internal circulation. The intake pipe, heat sink, exhaust pipe, and outer fan drive external circulation. By connecting the internal and external circulation, efficient cooling is achieved. The heat exchange plate on the guide shroud is in direct contact with the heat sink, allowing heat to be dissipated during the internal fan circulation. The guide grooves and heat-conducting plates also dissipate heat from inside the soundproof cover, ensuring effective cooling.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1 - Figure 6 As shown, this utility model is a dual-cycle high-efficiency cooling low-noise generator set protective cover, including a body 1. The body 1 includes a soundproof cover 11 with an internal sound insulation structure. Air intake pipes 12 are symmetrically arranged at the ends of the soundproof cover 11 for air intake, and exhaust pipes 13 are symmetrically arranged at the top of the soundproof cover 11 for exhaust. A heat dissipation plate 2 is mounted on the upper part of the body 1. Both ends of the heat dissipation plate 2 are connected to the exhaust pipes 13 and cooperate with the soundproof cover 11 to form an external circulation channel. Under the action of an external fan 7, air enters from the bottom through the air intake pipes 12, and the airflow passes through the soundproof cover 11 from bottom to top. The air enters the heat sink 2 through the guide groove 22 and is then discharged outward through the exhaust pipe 13. The airflow is fully divided by the symmetrically arranged intake pipe 12 and exhaust pipe 13, which ultimately achieves a better heat dissipation effect. An internal fan 5 is provided at the upper end of the body 1. A guide shroud 4 is installed at the upper end of the internal fan 5 to guide the airflow. The internal fan 5 and the guide shroud 4 are combined in the sound insulation cover 11 to form an internal circulation channel. When the internal circulation channel drives the airflow inside the sound insulation cover 11 to circulate to the guide shroud 4, it can conduct heat to the heat sink 2 through the heat exchange plate 3, and accelerate heat dissipation while circulating.

[0030] The heat sink 2 has uniformly distributed heat-conducting fins 21 inside. The heat-conducting fins 21 can divert airflow in the heat sink 2 to ensure uniformity. At the same time, they can quickly absorb the heat conducted by the heat exchange plate 3 and dissipate heat through full contact with the airflow. The heat sink 2 has a guide groove 22 that runs vertically through it. The path of the guide groove 22 is wavy. Between the body 1 and the heat exchange plate 3, there is a drive mechanism 6 that drives the air guide shroud 4 and the inner fan 5 to move along the path of the guide groove 22 in the body 1. The heat exchange plate 3 has a movable groove 31. The purpose of the cooperation between the guide groove 22, the movable groove 31 and the drive mechanism 6 is to increase the coverage area of ​​the air guide shroud 4 and the inner fan 5 inside the sound insulation cover 11, and at the same time play a turbulence role, so that the air inside the sound insulation cover 11 can flow fully, and then quickly dissipate heat in conjunction with the external circulation channel.

[0031] The air guide shroud 4 is made of low-cost aluminum alloy with good thermal conductivity. The air guide shroud 4 includes an air guide pipe 41 fixed at the air outlet of the inner fan 5. Symmetrical first air pipes 42 are provided on both sides of the air guide pipe 41, and symmetrical second air pipes 43 are provided at the lower ends of both sides of the air guide pipe 41. The first air pipes 42 and the second air pipes 43 are split in the air guide pipe 41 through the diverter plate 44.

[0032] The first air pipe 42 faces the inner side of the soundproof cover 11, the second air pipe 43 faces the lower side of the soundproof cover 11, and the air inlet of the inner fan 5 is located directly below the two second air pipes 43. Through the combination of the air intake of the inner fan 5 and the exhaust of the second air pipe 43, the airflow can be driven to flow upward from the middle of the soundproof cover 11, and then flow out from the side through the inner fan 5 and the guide cover 4 to form a circulation channel. The first air pipe 42 can prevent airflow at the top of the inner side of the soundproof cover 11.

[0033] The heat exchange plate 3 has its upper and lower surfaces in contact with the heat sink 2 and the air guide 4, respectively, and is used for temperature conduction between the two. When the heat exchange plate 3 is in contact with the air guide 4, it can conduct heat to the heat exchange plate 3 during the internal circulation through the air guide 4. When the heat exchange plate 3 is in contact with the heat sink 2, it can conduct heat outward. Then, the heat is carried outward through the external circulation channel connected to the heat sink 2. The contact between the three can improve the heat dissipation effect while ensuring the flexibility of the air guide 4 and the internal fan 5.

[0034] The drive mechanism 6 includes lead screws 61 symmetrically arranged and rotating in the soundproof cover 11, and internal threaded sleeves 62 fixed on both sides of the heat exchange plate 3 and threadedly engaged with the lead screws 61. The two lead screws 61 are synchronously driven by a motor and a pulley group, and the movement of the heat exchange plate 3 in the body 1 is formed by the spiral of the internal threaded sleeves 62. There are also slide rails 63 perpendicular to the lead screws 61 between the heat exchange plate 3 and the guide shroud 4. The slide rails 63 are arranged in two symmetrical sets, each set consisting of a track and a slide block, which are fixed to the sides of the heat exchange plate 3 and the guide shroud 4 respectively. The slide rails 63 can adapt to the position difference generated by the sliding of the drive column 64 in the guide groove 22, thereby driving the guide shroud 4 and the inner fan 5 to move twice on the heat exchange plate 3, ensuring the range of motion of the guide shroud 4 and the inner fan 5, and ensuring the overall air circulation inside the soundproof cover 11. The upper end of the guide shroud 4 is fixed with the drive column 64, which slides in the movable groove 31 and the guide groove 22.

[0035] The bottom of the air intake pipe 12 is connected to the bottom of the inner side of the soundproof cover 11, and the top is the air intake end. The air intake pipe 12 is also provided with several first sound-absorbing sheets 121 arranged in parallel. Increasing the length of the air intake pipe 12 and the first sound-absorbing sheets 121 arranged inside can achieve the noise reduction effect. At the same time, the first sound-absorbing sheets 121 arranged in parallel ensure the uniformity of air intake.

[0036] The exhaust pipe 13 is connected to the heat sink 2 at both ends and has an external fan 7 in the middle of the top surface to drive the airflow to circulate. The exhaust pipe 13 has several second sound-absorbing cotton 131 arranged in parallel inside, which leads the exhaust end of the exhaust pipe 13 to the middle of the upper end. Then, the second sound-absorbing cotton 131 arranged in parallel plays a role in noise reduction. The second sound-absorbing cotton 131 arranged in parallel can also play a role in diverting the flow and ensuring the uniformity of heat dissipation.

[0037] A specific application of this embodiment is as follows: the inner fan 5 and the drive mechanism 6 start simultaneously. The inner fan 5 drives the airflow from below upward and into the guide shroud 4. The airflow is then diverted by the diverter plate 44 in the guide shroud 4 and discharged from the first air pipe 42 and the second air pipe 43 on both sides. The start of the inner fan 5 can circulate the airflow inside the soundproof cover 11. The lead screw 61 rotates through the motor and pulley group and is threadedly engaged with the inner threaded sleeve 62 to drive the heat exchange plate 3 to move inside the soundproof cover 11. At the same time, the drive column 64 slides in the movable groove 31 and the guide groove 22, and finally drives the inner fan 5 to move along the path of the guide groove 22. The heat exchange plate 3, the guide shroud 4, and the inner fan 5 are adaptively connected by the slide rail 63. When the drive mechanism 6 drives the inner fan 5 to move to one end, the drive mechanism 6 reverses its operation, thereby repeatedly driving the inner fan 5 to move back and forth along the path of the guide groove 22 in the soundproof cover 11, which fully ensures the airflow inside the body 1.

[0038] In the process of the internal fan 5 blowing airflow to the airflow guide shroud 4, heat is transferred to the heat exchange plate 3 that is in contact with the airflow guide shroud 4, and the heat exchange plate 3 in turn transfers heat to the heat dissipation plate 2 and its internal heat conduction sheet 21 that are in contact with its upper end.

[0039] When the external fan 7 is working, it drives the external airflow to enter from the bottom inside the soundproof cover 11 through the air intake pipe 12. Then, the airflow enters the heat sink 2 from bottom to top inside the soundproof cover 11 through the guide groove 22 and is discharged outward through the exhaust pipe 13 at the end of the heat sink 2. At the same time, the heat sink 2 discharges heat and the heat conducted by the heat exchange plate 3 is also discharged simultaneously.
