Description

Technical Field

[0001] This utility model relates to the field of generator set equipment, and in particular to an air intake device for a generator set chassis. Background Technology

[0002] To ensure the safe, efficient, and long-term operation of generator sets, it is essential to avoid high temperatures during operation. Generally, a specialized air intake structure is used to dissipate heat from the equipment.

[0003] The air intake structure typically includes a fan for guiding airflow and an air inlet. The fan generates negative pressure inside the equipment to force external airflow into the equipment through the air inlet. The air inlet is usually equipped with a filter to block impurities in the airflow. Although the above structure can expel heat from the equipment in a timely manner, the airflow usually flows in and out of the equipment in a direct flow, resulting in little contact between the airflow and the internal components, insufficient heat exchange, and low heat dissipation efficiency.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

This reduces the flow velocity to a certain extent, increases the heat exchange time between the airflow and the equipment, and achieves full heat exchange. At the same time, it increases the diffusion range of the airflow and enhances the heat dissipation effect of the airflow. The combination of the deflector and the claw allows for quick disassembly of the air vent bracket.

[0006] To achieve the above objectives, this utility model provides an air intake device for a generator set chassis, comprising: The air outlet bracket is equipped with several filter holes for airflow to pass through, and the airflow forms an airflow channel through the filter holes; A deflector plate is connected to the side wall of the air outlet bracket where the airflow exits.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] See Figure 1 , Figure 2 and Figure 3 This utility model provides an air intake device for a generator set chassis, which includes: The air vent bracket 1 is provided with a plurality of filter holes 2 for airflow to pass through, forming an airflow channel; the plurality of filter holes 2 constitute an air intake group 20, and multiple air intake groups can be provided on the air vent bracket 1, which can be evenly arranged. As shown in the figure, the air vent bracket 1 is provided with an independent air intake group.

[0022] When external airflow passes through filter hole 2, the impurities it carries, such as dust and lint, will be blocked. This prevents impurities from entering the equipment and damaging the precision equipment.

[0023] The guide plate 3 is connected to the side wall of the air outlet bracket 1 where the airflow flows out. The guide plate has a curved or inclined surface that receives the airflow and changes its direction. The direction of the airflow after being guided has a predetermined angle with the direction of the airflow channel. After being impacted by the guided airflow, the direct airflow changes its direction and becomes turbulent airflow, which reduces the flow velocity to a certain extent, increases the heat exchange time between the airflow and the equipment, and achieves sufficient heat exchange. At the same time, it increases the diffusion range of the airflow and increases the heat dissipation effect of the airflow.

[0024] In this embodiment, the guide plate is a rotating structure with a gradually increasing slope from the center to the edge, and the guide plate is located at the center of the airflow channel. Using the guide plate with the above structure, the airflow located at the center can be guided to the surrounding areas, achieving uniform airflow diffusion.

[0025] In some embodiments of this application, since the distance between the device housing 100 and the internal device is set as needed, the distance between the guide plate and the air outlet bracket 1 also needs to be adjusted accordingly. Therefore, the guide plate is connected to the air outlet bracket 1 by a pull rod 4. The pull rod 4 passes through the air outlet bracket 1 and slides relative to the air outlet bracket 1. A limiting component 5 is installed at the end of the pull rod 4 away from the guide plate 3 to limit the axial movement distance of the pull rod 4.

[0026] Preferably, the limiting component 5 is a fixing head, or The limiting component 5 is a limiting nut. The end of the pull rod 4 is provided with a threaded structure. The limiting nut is screwed to the end of the pull rod 4. By rotating the limiting nut, the relative movement of the limiting nut at the end of the pull rod 4 can be realized, and the position of the limiting component 5 on the axis of the pull rod 4 can be adjusted to further limit the movement distance of the pull rod 4.

[0027] In order to facilitate the quick installation of the air outlet bracket 1 onto the equipment housing 100, this application provides multiple sets of locking structures on the side wall where the airflow exits from the air outlet bracket 1. See Figure 4 Each locking structure includes a claw 61 radially in the direction of the airflow channel and a mating groove 62 disposed on the equipment housing 100. The claw 61 includes a driving end 611 and a working end 612. The working end 612 of the claw 61 extends into the mating groove 62 to achieve relative locking between the air outlet bracket 1 and the equipment housing 100.

[0028] When installing the air vent bracket 1, simply drive the claw 61 to move radially towards the center along the airflow channel direction to insert the driving end 611 of the claw 61 into the mating groove 62, thus locking it in place. For disassembly, simply move the claw 61 in the opposite direction to disengage the driving end 611 from the mating groove 62, and then remove the air vent bracket 1.

[0029] To facilitate the synchronous driving of multiple sets of claws 61 and enable quick disassembly and installation of the air vent bracket 1, the multiple locking structures are evenly distributed in a ring around the axis of the airflow channel. When the pull rod 4 moves axially, the guide plate 3 presses against the driving end 611 of the claws 61, thereby driving the radial movement of the multiple sets of claws 61. Simultaneously, the air vent bracket 1 is provided with a claw bracket 63 for guiding the movement of the claws 61, and the claws 61 are slidably mounted on the claw bracket 63. An elastic element 64, which can be a spring, connects the claws 61 and the claw bracket 63.

[0030] Under normal conditions, the claw 61 is pulled by the elastic element 64 and is in the first working state near the center. When the lever 4 is pulled, the claw 61 enters the second working state away from the center under the outward pressing action of the guide plate 3.

[0031] During installation, first pull the lever 4 to put the claw 61 into the second working state. After the air outlet bracket 1 is installed into the equipment housing 100, then pull the lever 4, and the claw 61 is elastically reset to enter the first working state. The drive end 611 of the claw 61 is inserted into the mating groove 62 to achieve locking.

[0032] Disassembly can be performed by reversing the steps.

[0033] In summary, this utility model provides an air intake device for a generator set chassis, comprising: an air outlet bracket having several filter holes for airflow to pass through, forming an airflow channel; the filter holes constituting an air intake group, and multiple air intake groups can be arranged evenly on the air outlet bracket. As shown in the figure, an independent air intake group is provided on the air outlet bracket. When external airflow passes through the filter holes, impurities carried by it, such as dust and lint, are blocked, preventing impurities from entering the equipment and damaging precision equipment. A guide plate is connected to the side wall of the air outlet bracket where the airflow exits. The guide plate has a curved or inclined surface that receives the airflow and changes its direction; the direction of the airflow after being guided has a predetermined angle with the direction of the airflow channel; after being impacted by the guided airflow, the direct airflow changes its direction, becoming turbulent airflow, which reduces the flow velocity to a certain extent, increases the heat exchange time between the airflow and the equipment, and achieves sufficient heat exchange; at the same time, it increases the diffusion range of the airflow and enhances the heat dissipation effect.

[0034] This utility model can: 1. When the direct airflow is impacted by a portion of the airflow guided by the guide plate, the direction of the direct airflow will change, turning it into turbulent airflow. This reduces the flow velocity to a certain extent, increases the heat exchange time between the airflow and the equipment, and achieves sufficient heat exchange. At the same time, it increases the diffusion range of the airflow and enhances the heat dissipation effect of the airflow. 2. The combination of the air deflector and the clips allows for quick disassembly of the air vent bracket.

[0035] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
