[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 3 As shown, an embodiment of the utility model provides a ventilation component 10, which has a ventilation flow channel arranged throughout, and the ventilation flow channel is used for air circulation. The ventilation flow channel includes a circulation section 101 and a noise reduction chamber 102 that are interconnected to ensure the circulation effect of air when passing through the ventilation flow channel. The circulation section 101 and the noise reduction chamber 102 are distributed along the ventilation direction of the ventilation flow channel, so that when the air flows through the circulation section 101 and the noise reduction chamber 102, there is no need to change the circulation direction of the air, thereby increasing the circulation speed of the air and ensuring the ventilation effect of the ventilation component 10. The circulation area of ​​the circulation section 101 is smaller than the circulation area of ​​the noise reduction chamber 102. Specifically in the embodiment, the Y-axis direction is the ventilation direction.

[0029] By applying the technical solution of the utility model, the circulation section 101 and the noise reduction chamber 102 are interconnected, so that air can circulate between the circulation section 101 and the noise reduction chamber 102, and take away the heat around the ventilation component 10 in time. And the circulation section 101 and the noise reduction chamber 102 are distributed along the ventilation direction of the ventilation flow channel, so that the circulation speed of the air when flowing through the circulation section 101 and the noise reduction chamber 102 can be accelerated, the ventilation effect can be improved, and then the heat dissipation efficiency of the ventilation component 10 can be improved. The circulation area of ​​the circulation section 101 is set to be smaller than the circulation area of ​​the noise reduction chamber 102, which uses the sudden expansion and contraction of the cross-sectional area of ​​the cavity to cause the reflection and interference of the sound waves, thereby reducing the sound energy radiated outward to achieve the purpose of noise reduction. The circulation area in this application refers to the cross-sectional area of ​​the circulation section 101 or the noise reduction chamber 102 in the vertical air circulation direction. Through the above-mentioned setting, noise reduction can be achieved without affecting the ventilation effect.

[0030] Furthermore, the ventilation flow channel includes a plurality of noise reduction chambers 102 distributed at intervals, and a flow section 101 is provided between two adjacent noise reduction chambers 102. Through the above arrangement, noise will pass through a plurality of noise reduction chambers 102 when propagating, so that the ventilation flow channel can reduce noise multiple times, further improving the noise reduction effect of the ventilation assembly 10.

[0031] In one embodiment of the present application, the noise first enters the ventilation assembly 10 from the noise reduction chamber 102, then passes through the flow section 101, enters the next noise reduction chamber 102 for noise reduction, and flows out of the noise reduction chamber 102. In another embodiment of the present application, the noise can enter the ventilation assembly 10 from the flow section 101, then propagate to the noise reduction chamber 102 for noise reduction, then flow through the next flow section 101, and flow out of the flow section 101.

[0032] Among them, two adjacent noise reduction chambers 102 are staggered in the ventilation direction of the flow section 101. Through the above arrangement, the propagation path of the noise when passing through different noise reduction chambers 102 can be changed, thereby increasing the propagation distance of the noise in the ventilation flow channel, extending the propagation time of the noise in the ventilation component 10, increasing the energy consumption of the noise, and improving the noise reduction effect of the ventilation component 10. Specifically, the two adjacent noise reduction chambers 102 can be staggered in the ventilation direction of the flow section 101. Figure 1 The staggered distribution in the X-axis direction can also make the two adjacent noise reduction cavities 102 Figure 1 The staggered distribution in the Z-axis direction may also cause two adjacent noise reduction cavities 102 to be staggered in both the X-axis and Z-axis directions.

[0033] In other embodiments of the present application, two adjacent noise reduction chambers 102 may also be arranged without being misaligned, and the flow section 101 may be arranged to be inclined along the ventilation direction, as long as the propagation path of the noise is changed.

[0034] like Figure 4 As shown, the noise reduction chamber 102 has a first air inlet 103 and a first air outlet 104 that are relatively arranged along the ventilation direction, and the projection of the first air inlet 103 in the ventilation direction partially overlaps or does not overlap with the first air outlet 104. Through the above arrangement, the propagation path of the noise in the same noise reduction chamber 102 can be changed, avoiding the linear propagation of the noise in the ventilation flow channel. Through the above arrangement, the noise is changed multiple times in the propagation path, further increasing the energy loss of the noise, achieving multi-level noise reduction of the noise, and improving the noise reduction effect of the ventilation component 10. In addition, such an arrangement will also make the ventilation effect softer, avoiding the impact of excessive wind speed on the surrounding environment or equipment to produce secondary noise.

[0035] In the present application, the noise reduction cavity 102 has an expansion section 105 and a contraction section 106 distributed along the ventilation direction, the size of the expansion section 105 gradually increases along the ventilation direction, and the size of the contraction section 106 gradually decreases along the ventilation direction. Through the above structure, the sudden expansion and contraction of the flow area of ​​the noise reduction cavity 102 causes the reflection and interference of sound waves, thereby reducing the sound energy radiated outward, and further improving the noise reduction effect of the ventilation component 10 on noise.

[0036] Furthermore, the cross-sectional shape of the noise reduction chamber 102 perpendicular to the ventilation direction is a polygonal structure. With this arrangement, when the noise propagates into the noise reduction chamber 102, the sound waves will be reflected and interfered multiple times inside the noise reduction chamber 102, causing energy loss of the sound waves, thereby achieving a better noise reduction effect. In the present application, the noise reduction chamber 102 is a hexagonal structure. In other embodiments, the outline of the noise reduction chamber 102 can be other special-shaped structures such as a quadrilateral, an octagon, a circle or a wave, as long as the sound waves can be reflected inside it. In the present application, a straight section is also provided between the expansion section 105 and the contraction section 106, so that the internal space of the noise reduction chamber 102 can be increased, while increasing the angle change of the inner wall of the noise reduction chamber 102, thereby increasing the number of sound wave reflections and improving the noise reduction effect.

[0037] like Figure 3As shown, the ventilation assembly 10 has a plurality of ventilation channels arranged in parallel, and the ventilation channels have an air inlet side and an air outlet side arranged relatively, and the circulation section 101 and the noise reduction chamber 102 are staggeredly distributed on the air inlet side of the plurality of ventilation channels along the arrangement direction of the ventilation channels, and / or, the circulation section 101 and the noise reduction chamber 102 are staggeredly distributed on the air outlet side of the plurality of ventilation channels along the arrangement direction of the ventilation channels. In other embodiments of the present application, the circulation section 101 and the noise reduction chamber 102 are distributed on the air inlet side of the plurality of ventilation channels along the arrangement direction of the ventilation channels, and it is not limited whether the circulation section 101 and the noise reduction chamber 102 are staggeredly distributed at the air outlet side, or the circulation section 101 and the noise reduction chamber 102 are distributed on the air outlet side of the plurality of ventilation channels along the arrangement direction of the ventilation channels, and it is not limited whether the circulation section 101 and the noise reduction chamber 102 are staggeredly distributed on the air inlet side of the ventilation channels. In the present embodiment, the flow section 101 and the noise reduction chamber 102 are staggeredly distributed on the air inlet side and the air outlet side of multiple ventilation channels along the arrangement direction of the ventilation channels. Such an arrangement can make the air volume of the ventilation component 10 on the air inlet side and the air outlet side more uniform, avoiding a large difference in air volume at different positions on the air inlet side or the air outlet side, thereby affecting the ventilation and heat dissipation effects of the ventilation component 10.

[0038] In the present application, there are two forms of ventilation channel arrangement, one is to arrange the noise reduction chamber 102 on the air inlet side and the air outlet side of the ventilation channel, and the other is to arrange the flow section 101 on the air inlet side and the air outlet side of the ventilation channel. The two ventilation channels are arranged alternately, that is, multiple flow sections 101 and noise reduction chambers 102 are arranged alternately to form a honeycomb structure ventilation component 10, which achieves noise reduction for electrical equipment while ensuring good ventilation effect.

[0039] The ventilation assembly 10 includes a frame 11 and at least two guide plates 12. The two guide plates 12 are spaced apart in the frame 11, and the guide plates 12 are arranged in the frame 11 along the ventilation direction. A ventilation channel is formed between two adjacent guide plates 12, and the ventilation assembly 10 has multiple ventilation channels. The above device has a simple structure, and is convenient for targeted removal and rapid replacement of damaged guide plates 12. The frame 11 makes the structure of the multiple guide plates 12 more stable, and facilitates the installation of the ventilation assembly 10.

[0040] Specifically, the guide plate 12 and the frame 11 are made of metal. With this configuration, the ventilation assembly 10 can adapt well to high temperature, high humidity and corrosive gas environments, so that the ventilation assembly 10 has strong environmental adaptability. The guide plate 12 and the frame 11 are fixedly connected to further improve the stability of the overall structure of the ventilation assembly 10. Specifically, the guide plate 12 and the frame 11 can be connected by welding or fasteners.

[0041] In the present application, the guide plate 12 has a straight segment and a plurality of bent segments connected in series. The straight segments of two adjacent guide plates 12 cooperate to form a flow segment 101, and the plurality of bent segments of two adjacent guide plates 12 cooperate to form a honeycomb structured noise reduction cavity 102, so that the sound waves are reflected multiple times between the plurality of bent segments in the noise reduction cavity 102, thereby improving the noise reduction effect of the ventilation assembly 10.

[0042] A plurality of bending sections corresponding to a noise reduction cavity 102 on a guide plate 12 form a group of bending parts. In this embodiment, a plurality of straight sections and a plurality of bending parts can be provided on a guide plate 12. With such a design, a plurality of flow sections 101 and a plurality of noise reduction cavities 102 can be formed between two adjacent guide plates 12. In this way, noise propagates through a plurality of continuous noise reduction cavities 102, achieving multi-stage noise reduction. The above device has a simple structure, and the guide plate 12 can be integrally formed, which is convenient for processing.

[0043] Furthermore, the connection between the straight section and the bending section and between two adjacent bending sections are arc transitions. Through the above arrangement, the wind resistance can be effectively reduced, the flow rate of air passing through the guide plate 12 can be accelerated, and the heat dissipation effect of the ventilation component 10 can be improved.

[0044] like Figure 5 As shown, in another embodiment of the utility model, an energy storage system 20 is provided, and the energy storage system 20 includes a shell 21 and the above-mentioned ventilation assembly 10. Among them, a second air inlet 211 and a second air outlet 212 are arranged on the shell 21. The ventilation assembly 10 can be arranged at the second air inlet 211 or the second air outlet 212. In the present application, the ventilation assembly 10 is arranged at the second air inlet 211 and the second air outlet 212. In this way, the ventilation assembly 10 can be arranged at the noise propagation location of the energy storage system 20 to ensure the maximum noise reduction effect on the energy storage system 20 and reduce noise pollution. At the same time, the guide plate 12 can also filter impurities in the gas introduced into and discharged from the energy storage system 20.

[0046] 1. No need to add additional sound-absorbing materials, simple structure and low cost;

[0047] 2. Strong environmental adaptability, can be used in high temperature, high humidity and corrosive gas environment, not easy to age;
