Description

Technical Field

[0001] This utility model relates to the field of diesel generator set technology, specifically a novel diesel generator set air intake and exhaust device. Background Technology

[0002] A diesel generator set is a power supply device that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. It is widely used in emergency power supply, backup power supply and main power supply in areas with power shortages. The intake and exhaust system of a diesel generator set is a key link to ensure its normal operation, which directly affects the heat dissipation efficiency, combustion completeness and operational stability of the unit.

[0003] Chinese patent CN222296357U discloses a novel diesel generator set air intake and exhaust device. It utilizes a long, narrow air intake design to increase the air intake area, allowing more external air to enter the generator set casing and improving ventilation efficiency. After entering the casing through the air intake, the air flows through several branch pipes into the main pipe, then through the main pipe and fan, finally exiting through the exhaust pipe. This airflow carries away heat from the casing, ensuring a more even distribution of external air within the generator set casing. This results in more uniform ventilation and heat dissipation, preventing localized overheating. The air intake design also helps reduce the temperature gradient within the casing, further enhancing heat dissipation. The air duct design, with its connection to the partition, assists in further heat dissipation within the generator set casing, preventing internal heat accumulation.

[0004] While the aforementioned solutions utilize partitions and flanges within the enclosure to collect airflow, the inlet requires overall airflow within the enclosure to be established before the fan can enter. Furthermore, the fan's external location increases noise levels from the diesel generator set during operation. Therefore, we offer a novel diesel generator set air intake and exhaust system to address these issues. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of air intake and exhaust device for diesel generator sets.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel diesel generator set air intake and exhaust device, comprising;

[0009] The unit cabinet has air ducts on both sides. A first barrier box and a second barrier box are fixedly connected inside the unit cabinet. The internal cavity of the unit cabinet is divided into a first cavity, a second cavity, and a third cavity by the first barrier box and the second barrier box. A first ventilation pipe is embedded in the first barrier box, and the first cavity is connected to the second cavity through the first ventilation pipe. A second ventilation pipe is embedded in the second barrier box, and the third cavity is connected to the second cavity through the second ventilation pipe.

[0010] The circulation assembly, located on the unit cabinet, is used to circulate liquid within the first and second barrier boxes.

[0011] The first fan is located in the first cavity and is used to transport air through the first cavity to the second cavity.

[0012] The second fan is located inside the third chamber and is used to transport air through the second chamber to the third chamber.

[0013] The generator body is located inside the second cavity.

[0014] Furthermore, the exhaust end of the generator body is equipped with an exhaust pipe, and the top end of the exhaust pipe passes through the unit cabinet and extends to the outside of the unit cabinet.

[0015] Furthermore, the circulation component includes a base fixedly connected to the bottom surface of the unit cabinet, a fourth cavity is provided in the base, a conveying pipe is provided in the fourth cavity, and the two ends of the conveying pipe are respectively fixedly connected to the first barrier box and the second barrier box.

[0016] Furthermore, the circulation assembly also includes an inlet pipe fixedly connected to the first barrier box and an outlet pipe fixedly connected to the second barrier box, wherein the inlet pipe and the outlet pipe are respectively connected to two water pumps.

[0017] Furthermore, cabinet doors are hinged to both sides of the unit cabinet, and wiring holes are provided on the unit cabinet, which are connected to the second cavity.

[0018] Furthermore, sound-absorbing cotton is fixedly connected to both sides of the unit cabinet, and each of the two sound-absorbing cottons has an adapter hole that matches the air duct.

[0019] (iii) Beneficial effects:

[0020] Compared with existing technologies, the new diesel generator set's air intake and exhaust system has the following advantages:

[0021] I. This utility model separates three chambers through a first and second barrier box, forming a directional airflow channel with the first and second fans, allowing air to flow orderly between the first, second, and third chambers, improving the targeting and efficiency of ventilation. Furthermore, the circulation component drives the coolant to circulate within the first and second barrier boxes, utilizing the heat absorption properties of the liquid to cool the air flowing through the second chamber, effectively improving the heat dissipation effect on the generator body and ensuring the stable operation of the unit in high-temperature environments.

[0022] Second, this utility model avoids the noise diffusion caused by the fans being directly exposed to the external environment by having both the first and second fans built into the cavity of the unit cabinet; it also utilizes the sound-absorbing cotton installed on both sides of the unit cabinet to directly absorb the noise generated by the operation of the internal equipment, and the adapter holes on the sound-absorbing cotton cooperate with the air ducts to further block noise leakage without affecting ventilation, which greatly reduces the noise transmission during the operation of the diesel generator set and is more suitable for noise-sensitive scenarios.

[0028] 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 protection scope of the present utility model.

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: a novel diesel generator set air intake and exhaust device, including a unit cabinet 1, a circulation component, a first fan 8, a generator body 12, and a second fan 13.

[0030] Air ducts 20 are provided on both sides of the unit cabinet 1. The end of the air duct 20 near the inside of the unit cabinet 1 is the lower end. A first barrier box 3 and a second barrier box 4 are fixedly connected inside the unit cabinet 1. The internal cavity of the unit cabinet 1 is divided into a first cavity 9, a second cavity 10 and a third cavity 11 by the first barrier box 3 and the second barrier box 4. The first barrier box 3 and the second barrier box 4 are both hollow boxes. A first ventilation pipe 5 is embedded in the first barrier box 3. The first cavity 9 is connected to the second cavity 10 through the first ventilation pipe 5. The first barrier box 3 is a tubular structure, with its two ends located in the first cavity 9 and the second cavity 10 respectively. A second ventilation pipe 6 is embedded in the second barrier box 4. The third cavity 11 is connected to the second cavity 10 through the second ventilation pipe 6. The second ventilation pipe 6 is a tubular structure, with its two ends located in the second cavity 10 and the third cavity 11 respectively.

[0031] In this embodiment, the circulation component is installed on the unit cabinet 1 and is used to flow liquid in the first barrier box 3 and the second barrier box 4. The circulation component includes a base 15 fixedly connected to the bottom surface of the unit cabinet 1. A fourth cavity 18 is opened in the base 15. A conveying pipe 19 is installed in the fourth cavity 18. The two ends of the conveying pipe 19 are fixedly connected to the first barrier box 3 and the second barrier box 4, respectively.

[0032] There are at least two delivery pipes 19, which are connected to the first barrier box 3 and the second barrier box 4, so that the liquid in the first barrier box 3 can be delivered to the interior of the second barrier box 4 through the delivery pipes 19.

[0033] The circulation assembly also includes an inlet pipe 16 fixedly connected to the first barrier box 3 and an outlet pipe 17 fixedly connected to the second barrier box 4. The inlet pipe 16 and the outlet pipe 17 are respectively connected to two water pumps.

[0034] A water pump is used to deliver coolant through the inlet pipe 16 to the first barrier box 3, and then through the delivery pipe 19 on the first barrier box 3 to the interior of the second barrier box 4. After the second barrier box 4 is filled, it is discharged through the outlet pipe 17. The water in the first barrier box 3 can be used to cool the air entering the second cavity 10, thereby improving the heat dissipation effect on the generator body 12.

[0035] Specifically, the first fan 8 is installed in the first cavity 9 and is used to transport air through the first cavity 9 to the second cavity 10. After the first fan 8 is working, the gas in the first cavity 9 is transported through the first ventilation pipe 5 on the first barrier box 3 to the generator body 12.

[0036] Specifically, the second fan 13 is installed in the third cavity 11 to deliver air through the second cavity 10 to the third cavity 11. After the second fan 13 is working, the gas in the second cavity 10 is drawn into the third cavity 11 through the second ventilation pipe 6.

[0037] In this embodiment, the generator body 12 is disposed in the second cavity 10, and the exhaust end of the generator body 12 is equipped with an exhaust pipe 14. The top end of the exhaust pipe 14 penetrates the unit cabinet 1 and extends to the outside of the unit cabinet 1. The exhaust gas generated after the generator body 12 is working will be transported to the outside through the exhaust pipe 14.

[0038] The unit cabinet 1 has cabinet doors 2 hinged on both sides. The unit cabinet 1 has a cable hole 7, which is connected to the second cavity 10. The cabinet door 2 allows for easy maintenance of the generator body 12 inside the unit cabinet 1, while the cable hole 7 allows the output cable of the generator body 12 to extend out of the unit cabinet 1.

[0039] Both sides of the unit cabinet 1 are fixedly connected with sound-absorbing cotton 21. Each of the two sound-absorbing cotton 21 has an adapter hole 22 that matches the air duct 20. The sound-absorbing cotton 21 itself has the attraction performance to reduce the noise generated by the generator body 12 from being transmitted to the outside of the unit cabinet 1. In addition, the first barrier box 3 and the second barrier box 4 can also form a barrier to reduce noise leakage.
