Description

Technical Field

[0001] This utility model relates to the field of ventilation technology, and more specifically, to a ventilation and sound insulation sealing plate structure. Furthermore, it also relates to a power compartment cover including the aforementioned ventilation and sound insulation sealing plate structure. Background Technology

[0002] In existing technologies, construction machinery often operates under high loads and generates significant heat during operation, requiring cooling devices to dissipate this heat into the external environment. Therefore, ventilation of the engine compartment cover is an indispensable guarantee for the stable operation of construction machinery. However, the openings created by the ventilation structure can significantly reduce the sound insulation performance of panel structures like the engine compartment cover 01. Furthermore, due to heat dissipation requirements, ventilation paths are typically provided on the engine compartment cover, usually in the form of repeatedly arranged ventilation holes or louvered structures. According to the sound insulation law, even with a small ventilation area, the sound insulation performance of the panel structure will be significantly lower compared to a structure without ventilation holes. That is, using arranged openings (such as...) on the cover 01... Figure 1 As shown), honeycomb openings (such as...) Figure 2 As shown), blinds (such as Figure 3 Structures such as those shown can improve ventilation, but they are not good at sound insulation and can easily cause sound inside the cabin to radiate directly to the outside.

[0003] In conclusion, how to provide a sealing structure for the engine compartment that can meet the heat dissipation requirements of the engine compartment and also has good sound insulation performance is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a ventilation and sound insulation sealing plate structure that can be used as a sealing structure for the engine room, which can meet the heat dissipation requirements of the engine room and has good sound insulation performance.

[0005] Another objective of this invention is to provide a power compartment cover that includes the aforementioned ventilation and sound insulation sealing plate structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ventilation and sound insulation sealing plate structure includes at least two vertically distributed partitions, which cooperate to form a cavity. The upper partition has an air inlet, and the lower partition has an air outlet. Gas flows in from the air inlet and is discharged from the air outlet. The flow trajectory of the gas is not linear.

[0008] In one embodiment, the partition includes a first partition, a second partition disposed parallel to the lower part of the first partition, and a third partition for cooperating with the first partition to form the cavity. The second partition is located above the third partition. The first partition has the air inlet, and the third partition has the air outlet. The size of the air inlet and the air outlet are both smaller than the size of the second partition.

[0009] In one embodiment, the third partition includes a bottom plate and a side plate having the air outlet, the side plate being perpendicularly disposed on the four sides of the bottom plate, and the bottom plate being parallelly disposed below the second partition.

[0010] In one embodiment, the base plate and the side plate are an integral structure.

[0011] In one embodiment, the second partition and the side plate are spaced apart.

[0012] In one embodiment, sound-absorbing cotton is provided on the side panel.

[0013] In one embodiment, the second partition is disposed below the first partition via a column.

[0014] In one embodiment, the second partition is provided with sound-absorbing cotton.

[0015] In one embodiment, the partition comprises an iron plate.

[0016] A power compartment cover, comprising the ventilation and sound insulation sealing panel structure described in any one of the above claims.

[0017] When using the ventilation and sound insulation sealing plate structure provided by this utility model, the upper partition is provided with an air inlet, which also serves as the air inlet for engine compartment heat dissipation, and the lower partition is provided with an air outlet, which also serves as the air outlet for engine compartment heat dissipation. Ventilation structures such as vents can be provided on the partitions that form the cavity to ensure sufficient ventilation area in the engine compartment, so as to facilitate effective heat dissipation of the engine compartment's heat dissipation airflow.

[0018] During operation, the cooling airflow from the engine compartment enters the cavity through the air inlet and exits through the air outlet. Because the gas flow within the cavity is not linear—it repeatedly flows back and forth between the partitions, creating turbulent flow—sound from inside the engine compartment cannot be directly radiated to the outside through the ventilation structures (such as the air inlet and outlet). The sound is attenuated by repeated reflections between the partitions, thus reducing sound radiation. In other words, this device ensures sufficient ventilation area within the engine compartment while preventing direct sound radiation from the ventilation openings. The repeated reflections between the partitions attenuate the sound, reducing sound radiation and achieving effective sound insulation.

[0019] In summary, the ventilation and sound insulation sealing plate structure provided by this utility model can be used as a sealing structure for the engine room, which can not only meet the heat dissipation requirements of the engine room, but also has good sound insulation performance.

[0020] In addition, this utility model also provides a power compartment cover including the above-mentioned ventilation and sound insulation sealing plate structure. Attached Figure Description

[0031] 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.

[0032] The core of this invention is to provide a ventilation and sound insulation sealing plate structure, which can serve as a sealing structure for the engine compartment. It meets the heat dissipation requirements of the engine compartment while also possessing good sound insulation performance. Another core aspect of this invention is to provide a engine compartment cover that includes the aforementioned ventilation and sound insulation sealing plate structure.

[0033] Please refer to Figure 4 and Figure 5 , Figure 4 A schematic diagram of the ventilation and sound insulation sealing plate structure provided by this utility model; Figure 5 This is a cross-sectional view of the ventilation and sound insulation sealing panel structure.

[0034] This specific embodiment provides a ventilation and sound insulation sealing plate structure, including at least two vertically distributed partitions 1. The two partitions 1 cooperate to form a cavity. The upper partition 1 is provided with an air inlet 2, and the lower partition 1 is provided with an air outlet 3. Gas flows in from the air inlet 2 and is discharged from the air outlet 3. The gas flow trajectory is not linear.

[0035] It should be noted that the gas flow trajectory is not linear. This can mean that the gas does not enter directly from the inlet 2 and exit directly from the outlet 3. The inlet 2 and outlet 3 can be staggered or perpendicular (for example, the inlet 2 is in a horizontal plane and the outlet 3 is in a vertical plane) to make the gas flow trajectory non-linear. Alternatively, the inlet 2 and outlet 3 can be aligned, and other obstructions (including baffles or baffles) can be placed between them to change the gas flow trajectory. In practical applications, the baffle 1, inlet 2, and outlet 3 can be determined according to the actual situation and requirements.

[0036] When using the ventilation and sound insulation sealing plate structure provided by this utility model, the upper partition 1 is provided with an air inlet 2, which is also the air inlet for engine compartment heat dissipation, and the lower partition 1 is provided with an air outlet 3, which is also the air outlet for engine compartment heat dissipation. Ventilation structures such as vents can be provided on the partition 1 that constitutes the cavity to ensure that there is sufficient ventilation area in the engine compartment so that the heat dissipation airflow in the engine compartment can be effectively cooled.

[0037] During operation, the cooling airflow from the engine compartment enters the cavity through inlet 2 and exits through outlet 3. Because the gas flow within the cavity is not linear—it repeatedly flows back and forth between partitions 1, creating turbulent flow—sound from inside the engine compartment cannot be directly radiated to the outside through the ventilation structure (e.g., inlet 2 and outlet 3). The sound is attenuated by repeated reflections between partitions 1, thus reducing sound radiation. In other words, this device ensures sufficient ventilation area within the engine compartment while preventing direct sound radiation from the ventilation openings. The repeated reflections between partitions 1 attenuate the sound, reducing sound radiation and achieving effective sound insulation.

[0038] In summary, the ventilation and sound insulation sealing plate structure provided by this utility model can be used as a sealing structure for the engine room, which can not only meet the heat dissipation requirements of the engine room, but also has good sound insulation performance.

[0039] In one embodiment, such as Figure 1 and Figure 2 As shown, the partition 1 includes a first partition 11, a second partition 12 parallel to the lower part of the first partition 11, and a third partition 13 for cooperating with the first partition 11 to form a cavity. The second partition 12 is located above the third partition 13. The first partition 11 is provided with an air inlet 2, and the third partition 13 is provided with an air outlet 3. The dimensions of the air inlet 2 and the air outlet 3 are both smaller than the dimensions of the second partition 12.

[0040] It should be noted that this device may include three partitions 1. The outer perimeter of the third partition 13 can enclose the first partition 11 to form a cavity. The first partition 11 is the air inlet for cabin cooling airflow, and an air inlet 2 is provided in the middle of the first partition 11, i.e., an opening in the middle of the first partition 11 to facilitate gas entry. The second partition 12 is the middle partition 1, used to disrupt the gas flow trajectory. The third partition 13 has an air outlet 3 in the middle, i.e., an opening in the middle of the third partition 13 to facilitate gas exit. The dimensions of both the air inlet 2 and the air outlet 3 are smaller than the dimensions of the second partition 12, so that the cabin cooling airflow flows in from the air inlet 2, bypasses the second partition 12, and finally flows out from the air outlet 3, avoiding the cabin cooling airflow directly flowing in from the air inlet 2 and out from the air outlet 3 (if the dimensions of both the air inlet 2 and the air outlet 3 are larger than the dimensions of the second partition 12, the gas may flow in and out directly).

[0041] It should also be noted that, based on actual heat dissipation requirements, relatively small heat dissipation holes can be provided on each of the partitions 1. The opening area of ​​each partition 1 and the distance between two partitions 1 can be adjusted to ensure sufficient ventilation area within the engine compartment while preventing sound from directly radiating to the outside through the heat dissipation holes. The sound is attenuated by repeated reflections between the partitions 1, thus reducing sound radiation. In practical applications, the dimensions of the air inlet 2, air outlet 3, and the second partition 12 can be determined according to actual heat dissipation needs.

[0042] In one embodiment, the third partition 13 includes a bottom plate 14 and a side plate 15 with an air outlet 3. The side plate 15 is perpendicularly disposed on the four sides of the bottom plate 14, and the bottom plate 14 is parallel to the bottom of the second partition 12, so that the third partition 13 and the first partition 11 form a cavity, and the second partition 12 can be accommodated in the cavity to disrupt the gas flow trajectory.

[0043] In one embodiment, the base plate 14 and the side plate 15 are an integral structure to simplify the assembly process of the device.

[0044] In one embodiment, the second partition 12 and the side plates 15 are spaced apart. That is, the size of the second partition 12 is slightly larger than the size of the opening (air inlet 2) of the first partition 11, and a certain gap is left between the second partition 12 and the four side plates 15 of the third partition 13, so that the airflow can flow into the air outlet 3 from the surrounding gaps and then be discharged outward.

[0045] In one embodiment, sound-absorbing cotton 4 is provided on the side plate 15 to improve the sound absorption effect of the device by attaching the sound-absorbing cotton 4 to the side plate 15 while ensuring heat dissipation. In addition, an appropriate amount of sound-absorbing cotton can be attached to the wall surface of all partitions 1 to ensure smooth airflow.

[0046] In one embodiment, the second partition 12 is positioned below the first partition 11 via a column 5. That is, mounting holes can be provided at corresponding positions on the first partition 11 and the second partition 12, and the column 5 is installed in the corresponding mounting holes using fasteners. This securely connects the first partition 11 and the second partition 12, ensuring that the second partition 12 is parallel to the first partition 11 below it. When either the first partition 11 or the second partition 12 is damaged, the damaged component can be replaced by disassembly, allowing the new component to continue working with other undamaged components, thereby improving the device's lifespan and reducing maintenance costs.

[0047] In one embodiment, the second partition 12 is provided with sound-absorbing cotton 4 to improve the sound absorption effect of the device by attaching the sound-absorbing cotton 4 to the second partition 12 while ensuring heat dissipation. Additionally, to ensure smooth airflow, an appropriate amount of sound-absorbing cotton can be attached to the walls of all partitions 1.

[0048] In one embodiment, the partition 1 comprises an iron plate to improve the service life and performance of the device.

[0049] It should be noted that this application utilizes a three-layer partition 1 to attenuate sound within the cavity, thereby reducing noise radiation. Furthermore, sound-absorbing cotton can be adhered to the surface of any partition 1, while ensuring unobstructed airflow, to enhance sound absorption. Additionally, the opening area of ​​each partition 1 is relatively large to guarantee effective heat dissipation. This multi-layered partition 1 structure, while ensuring adequate heat dissipation, guarantees sufficient ventilation area while reducing sound radiation. This device is not only suitable for cabin ventilation structures but can be used in any situation requiring both sound insulation and ventilation.

[0050] In addition to the ventilation and sound insulation sealing plate structure described above, this utility model also provides a power compartment cover that includes the ventilation and sound insulation sealing plate structure disclosed in the above embodiments. For the structure of other parts of the power compartment cover, please refer to the prior art, which will not be repeated here.

[0051] It should be noted that the first partition 11, the second partition 12, and the third partition 13 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.

[0052] In addition, it should be noted that the orientation or positional relationship of the "entering and exiting" indications in this application is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of simplifying the description and making it easier to understand, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
