Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, and in particular to an energy storage device. Background Art

[0002] Ventilation and sound-absorbing shutters are widely used in industrial, commercial and household fields, especially in the import and export scenes where ventilation is required. Ventilation and sound-absorbing shutters not only have certain sound insulation and sound absorption effects while ensuring air circulation, but also have certain aesthetics due to their thin thickness and do not occupy space. However, for high-power energy storage thermal management systems, the cooling fan inside has a large air volume, high flow rate, and high air outlet temperature; the existing shutters cannot meet these working conditions. When facing such energy storage equipment, the shutters currently on the market have high ventilation and heat dissipation requirements and very large resistance, which makes it difficult to ensure the noise reduction effect. It is also easy to cause problems such as heat not being able to dissipate in time and deformation of the shutter blades. Summary of the invention

[0003] The object of the present invention is to provide an energy storage device with high strength, good sound-absorbing and noise-reducing effect and high heat dissipation efficiency.

[0004] To achieve this object, the present invention adopts the following technical scheme: an energy storage device, comprising an energy storage device body, a heat dissipation cabinet and a muffler, wherein a heat dissipation chamber is provided on one side of the energy storage device body, and the heat dissipation chamber is provided with a first installation port; the heat dissipation cabinet is installed in the heat dissipation chamber, and the air outlet of the heat dissipation cabinet is arranged toward the first installation port; the muffler comprises an air guide and a muffler louver, wherein the muffler louver is connected to the energy storage device body and covers the first installation port, wherein the muffler louver comprises a frame, a plurality of blades and a reinforcement structure, wherein the plurality of blades are arranged in the frame at intervals along the vertical direction and are all connected to the reinforcement structure, wherein the air guide is located between the heat dissipation cabinet and the frame, and the two sides of the air guide are respectively close to the heat dissipation cabinet and the frame to define an air guide channel between the air outlet and the blades, and the air guide, the frame and the reinforcement structure are all filled with sound absorbing members.

[0005] Preferably, the reinforcement structure comprises a vertical reinforcement plate, and two ends of the reinforcement plate are respectively connected to the inner top surface of the frame and the inner bottom surface of the frame.

[0006] Preferably, a guide portion is provided on a side of the reinforcing plate facing the air outlet, and a cross-section of the guide portion is triangular.

[0007] Preferably, a plurality of reinforcing plates are provided, and the plurality of reinforcing plates are arranged at intervals along the length direction of the blade, and the number of the reinforcing plates is proportional to the length dimension of the blade.

[0008] Preferably, the inner diameter of the air guide member gradually increases along the air outlet direction of the air outlet.

[0009] Preferably, in the vertical direction, both sides of the blade are convex curved surfaces or flat surfaces.

[0010] Preferably, in the vertical direction, one side of the blade is a convex curved surface, and the other side is a concave curved surface.

[0011] Preferably, in the vertical direction, one side of the blade is a convex V-shaped surface, and the other side is a concave V-shaped surface.

[0012] Preferably, in the air outlet direction of the air outlet, one end of the blade horizontally away from the air outlet is arranged to be tilted upward or tilted downward.

[0013] Preferably, in the vertical direction along the inclination direction of one end of the blade away from the air outlet, the inclination angles of the plurality of blades increase sequentially.

[0014] Beneficial effects of the present invention: by setting the air guide and the silencer louver, the air guide can play a sealing role between the air outlet of the heat dissipation cabinet and the silencer louver, prevent the hot air blown out of the air outlet from leaking into the heat dissipation chamber, causing problems such as hot air backflow and noise leakage, and can decelerate and reduce the pressure of the hot air, prolong the residence time of the hot air, and increase the noise reduction range. The silencer louver and the air guide cooperate to achieve the hot and cold isolation between the hot air discharged from the heat dissipation cabinet and the fresh air inhaled, effectively reduce the heat island effect, and improve the energy efficiency and heat dissipation efficiency of the whole machine. The blades of the silencer louver are connected to the reinforcement structure, and the structural strength of the blade is improved to avoid deformation of the blade under the premise of ensuring ventilation. The sound absorbing parts inside the air guide, the sound absorbing parts inside the frame and the sound absorbing parts inside the reinforcement structure cooperate to absorb noise on the entire path of the hot air flow, greatly enhancing the noise reduction effect of the muffler. In addition, the air guide is installed between the heat dissipation cabinet and the silencer louver, and the reinforcement structure is arranged in the frame, which can effectively improve the space utilization rate of the muffler, reduce the volume of the muffler, and improve the practicality of the muffler.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] The current blinds on the market cannot adapt to these working conditions when facing high-power energy storage thermal management systems because the cooling fans inside have large air volume, high flow rate and high air outlet temperature. The ventilation and heat dissipation requirements are high and the resistance will be very large, which makes it difficult to ensure the noise reduction effect. It is also easy for heat to not be dissipated in time, and the blinds blades to deform under high wind resistance.

[0040] In the related art, some energy storage thermal management systems have begun to use multi-layered silencers to solve the above problems. The noise reduction blades in the silencer are arranged in multiple layers along the air outlet direction of the heat dissipation fan, thereby reducing the noise of the hot air multiple times and achieving noise reduction of the fan with large air volume. However, the width of such silencers in the air outlet direction of the heat dissipation fan is very large, and some even protrude more than one meter from the energy storage container, which is not only inconvenient for loading and unloading, but also seriously affects the layout of the energy storage thermal management system.

[0041] Reference Figures 1 to 15 As shown, an energy storage device provided according to an embodiment of the present application includes an energy storage device body 100, a heat dissipation cabinet 200 and a muffler 300. The energy storage device body 100 is composed of a container and a thermal management system installed in the container. A heat dissipation chamber 110 is provided on one side of the energy storage device body 100. The heat dissipation chamber 110 is formed by surrounding a plurality of high-strength frame brackets 120. The heat dissipation chamber 110 is provided with a first installation port 111 and a second installation port 112.

[0042] The heat dissipation cabinet 200 is installed in the heat dissipation chamber 110 , the air outlet 210 of the heat dissipation cabinet 200 is arranged toward the first installation opening 111 , and the air inlet 220 of the heat dissipation cabinet 200 is arranged toward the second installation opening 112 .

[0043] The silencer 300 includes an air guide 310 and a sound-absorbing louver 320. The air guide 310 is a rectangular ring structure that matches the shape of the first mounting port 111. The sound-absorbing louver 320 is connected to the energy storage device body 100 and covers the first mounting port 111. The sound-absorbing louver 320 includes a frame 321, a plurality of blades 322 and a reinforcement structure 323. The plurality of blades 322 are arranged in the frame 321 at intervals along the vertical direction and are all connected to the reinforcement structure 323. A heat dissipation port 3221 for hot air to flow is formed between two adjacent blades 322, the reinforcement structure 323 and the frame 321. Optionally, the frame 321 of the sound-absorbing louver 320 can be fixedly connected to the frame bracket 120 by screwing, clamping, welding, etc., so as to ensure the installation stability of the sound-absorbing louver 320. The frame 321 of the sound-absorbing shutter 320 can also be hinged to one of its frame brackets 120 on one side, and locked with another frame bracket 120 through a locking structure on the other side, so as to facilitate users to open or close the heat dissipation chamber 110 and improve the user experience.

[0044] The air guide 310 is installed on the frame bracket 120 and is located between the heat dissipation cabinet 200 and the frame 321, and the two sides of the air guide 310 are respectively close to the air outlet surface where the air outlet 210 of the heat dissipation cabinet 200 is located and the frame 321, so as to define an air guide channel between the air outlet 210 and the blade 322, wherein the inner ring edge of the air guide 310 does not exceed the outer edge of the thermal management unit, that is, the projection of the inner ring of the air guide 310 on the outlet cover is located inside the projection of the heat dissipation cabinet 200 on the outlet cover. The air guide 310, the frame 321 and the reinforcement structure 323 are all hollow sandwich structures, and the air guide 310, the frame 321 and the reinforcement structure 323 are filled with sound absorbing components. Optionally, the sound absorbing component is sound absorbing cotton, sound absorbing cloth, polyester fiber or sound insulation felt, etc., which will not be repeated here.

[0045] It can be understood that by providing the air guide 310 and the silencer louver 320, on the one hand, the air guide 310 can play a sealing role between the air outlet 210 and the silencer louver 320 of the heat dissipation cabinet 200, so that the hot air blown out of the air outlet 210 is completely discharged from the silencer louver 320, thereby preventing the hot air blown out of the air outlet 210 from leaking into the heat dissipation chamber 110, causing problems such as hot air reflux and noise leakage. And since the air outlet 210 is usually only arranged in the upper half (or lower half) of the heat dissipation cabinet 200, and the air guide 310 and the silencer louver 320 are matched with the first mounting port 111 formed by the frame bracket 120, that is, the air guide 310 and the silencer louver 320 are long from top to bottom, therefore, the air outlet area of ​​the air guide channel formed by the air guide 310 (that is, the total projection area of ​​the heat dissipation port 3221 on the air outlet surface) and the total flow area of ​​the silencer louver 320 (that is, the projection area of ​​the silencer louver 320 on the air outlet surface) are much larger than the air outlet area on the front of the air outlet 210. The hot air blown out from the air outlet 210 enters the air guide channel, which disperses the airflow and greatly reduces the hot air volume, ensuring that the flow velocity of the hot air at the heat dissipation port 3221 of the silencer louver 320 is reduced as much as possible, thereby reducing wind resistance loss, prolonging the residence time of the hot air passing through the silencer 300, increasing the noise reduction range, and effectively reducing the noise of the airflow.

[0046] On the other hand, the sound-absorbing louvers 320 and the air guide 310 cooperate with each other. The air guide 310 can achieve the hot and cold separation between the hot air discharged by the heat dissipation cabinet 200 and the fresh air inhaled, and the sound-absorbing louvers 320 can increase the physical distance of the hot and cold separation, thereby effectively reducing the heat island effect and improving the energy efficiency and heat dissipation efficiency of the whole machine.

[0047] Compared with filling the blades 322 with sound absorbing parts, by setting the reinforcement structure 323, the blades 322 of the muffler shutter 320 are connected to the reinforcement structure 323, and the integrity of the blades 322 is higher. Under the premise of ensuring ventilation, the structural strength of the blades 322 is improved, thereby improving the impact resistance of each blade 322 and avoiding deformation of the blades 322. The sound absorbing parts inside the air guide 310, the sound absorbing parts inside the frame 321 and the sound absorbing parts inside the reinforcement structure 323 can absorb noise on the entire path of the hot air flow, greatly enhancing the noise reduction effect of the muffler 300.

[0048] In addition, compared with setting multiple layers of blades in the air outlet direction (i.e., in the horizontal direction from the heat dissipation cabinet 200 to the direction of the muffler 300), the air guide 310 is installed between the heat dissipation cabinet 200 and the muffler louver 320, and the reinforcement structure 323 is arranged in the frame 321. Under the premise of ensuring the noise reduction effect and heat dissipation efficiency, the space utilization rate of the muffler 300 can be effectively improved. The blades 322 can be set in only one layer in the air outlet direction, which reduces the volume of the muffler 300, facilitates the loading and unloading of the muffler 300 and facilitates the layout of the energy storage system, so that the muffler 300 can adapt to the use scenarios with limited space, thereby improving the practicality of the muffler 300.

[0049] It should be noted that in order to facilitate the sound absorbing component to absorb noise, the inner wall of the air guide 310, the inner wall of the frame 321 and the side wall of the reinforcement structure 323 are provided with a plurality of sound absorbing holes. The air guide 310, the frame 321 and the reinforcement structure 323 can absorb noise into the sound absorbing component through the sound absorbing holes, thereby further enhancing the noise reduction effect of the silencer 300.

[0050] It should also be noted that multiple sound-absorbing louvers 320 can be provided, and multiple sound-absorbing louvers 320 are arranged at intervals in the vertical direction, and the total height of the multiple sound-absorbing louvers 320 is equal to the height of the first mounting port 111. By providing multiple sound-absorbing louvers 320 and using multiple sound-absorbing louvers 320 in combination, problems such as the length of a single sound-absorbing louver 320 being too long and the long side strength of the frame 321 being insufficient can be avoided, thereby further improving the structural strength of the sound-absorbing louvers 320. In addition, users can also set different numbers of sound-absorbing louvers 320 according to the height size of the energy storage device, effectively improving the modularity of the silencer 300.

[0051] It should also be noted that a muffler 300 is also provided at the second installation opening 112 , and the muffler 300 at the second installation opening 112 can absorb the noise when the cooling cabinet 200 inhales cold air, thereby reducing the overall operating noise of the energy storage device.

[0052] Furthermore, the inner diameter of the air guide member 310 gradually increases along the air outlet direction of the air outlet 210. Specifically, along the air outlet direction of the air outlet 210, the thickness of the inner wall of the air guide member 310 gradually decreases, that is, the inner wall of the air guide member 310 presents a certain decreasing slope in the horizontal direction from the heat dissipation cabinet 200 to the direction of the sound-absorbing louver 320, so that the inner wall of the air guide member 310 presents a trumpet-shaped structure that opens toward the sound-absorbing louver 320.

[0053] By gradually increasing the inner diameter of the air guide 310, the difference in air outlet area between the air guide 310 and the air outlet 210 can be gradually increased in the air outlet direction, further guiding the hot air diffusion flow entering the air guide channel, and enhancing the deceleration and noise reduction effect of the air guide 310 on the hot air.

[0054] Reference Figure 2 As shown, it can be understood that the reinforcement structure 323 includes a vertical reinforcement plate, and in the air outlet direction of the air outlet 210, the width of the reinforcement plate, the width of the blade 322 and the height of the frame 321 are equal. The two ends of the reinforcement plate are connected to the inner top surface of the frame 321 and the inner bottom surface of the frame 321 respectively.

[0055] By providing a reinforcing plate, on the one hand, the plurality of blades 322 are connected to the reinforcing plate, and the structure of the sound-absorbing louver 320 can be effectively simplified under the premise of ensuring that the blades 322 have sufficient structural strength; on the other hand, according to the noise reduction theoretical formula:

[0056] ΔL=Φ(a)*L*P / S;

[0057] P = 2*(D1+D2);

[0058] S=D1*D2

[0059] Among them, ΔL is the sound attenuation of the silencer 300 at a certain flow rate (dB); Φ(a) is the static sound absorption coefficient (dB) obtained by the sound absorbing member a0; a0 is the sound absorption coefficient measured by the standing wave tube method. In this embodiment, Φ(a)=1.6a0; L is the protruding thickness of the silencer louver 320 (i.e., the height of the silencer louver 320 in the air outlet direction of the air outlet 210) (m); P is the circumference of the cross-section inside the single air duct (m); S is the cross-sectional area inside the single air duct (㎡); D1 is the length of the blade 322 (m), and D2 is the distance between two adjacent blades 322 (m).

[0060] It can be seen that by setting the reinforcement plate, the perimeter P of the single air duct inner cross-section and the area S of the single air duct inner cross-section in the formula are increased. Since the rate of area increase is usually greater, the sound attenuation of the muffler 300 will be significantly reduced. After testing, after adding a reinforcement plate, the sound attenuation is more than twice that of not adding a reinforcement plate.

[0061] Furthermore, a plurality of reinforcing plates are provided, and the plurality of reinforcing plates are arranged at intervals along the length direction of the blade 322 , and the number of the reinforcing plates is proportional to the length dimension of the blade 322 .

[0062] In order to optimize the overall force-bearing structure of the sound-absorbing louver 320, the reinforcing plates are arranged equidistantly and the number of reinforcing plates is proportional to the length of the blade 322. For example, when the length of the blade 322 exceeds 1m, the number of reinforcing plates is increased by one for every 0.5m increase in the length of the blade 322. By providing multiple reinforcing plates, the blade 322 with a longer length can be reinforced, effectively improving the overall structural stability of the sound-absorbing louver 320.

[0063] Reference Figure 1 and Figure 3 As shown, it can be understood that a guide portion 3231 is provided on one side of the reinforcing plate facing the air outlet 210 (ie, the windward side of the reinforcing plate), and the cross section of the guide portion 3231 is triangular.

[0064] By providing a guide portion 3231 with a triangular cross-section, the guide portion 3231 can reduce the contact area between the reinforcing plate and the hot air, and guide the hot air to quickly enter the heat dissipation port 3221, which is beneficial to reduce wind resistance, further improve the heat dissipation efficiency of the silencer louver 320 and reduce the impact on the silencer louver 320.

[0065] Reference Figure 4 and Figure 5 As shown, it can be understood that in the vertical direction, both sides of the blade 322 are planes.

[0066] Setting both sides of the blade 322 as planes can greatly simplify the structure of the blade 322 , facilitate the design and processing of the blade 322 , and reduce the production cost of the sound-absorbing shutter 320 .

[0067] In some embodiments, in the air outlet direction of the air outlet 210 , the blades 322 with flat surfaces on both sides are arranged with one end thereof horizontally away from the air outlet 210 tilted upward or tilted downward.

[0068] The user can set the arrangement direction of the blades 322 with both sides being flat to meet different blowing requirements according to actual conditions. For example, in the case of a simple manufacturing process and the wind blowing downward toward the bottom of the container, the blades 322 with both sides being flat can be arranged with one end away from the air outlet 210 tilted downward. In the case of a simple manufacturing process and the wind blowing upward toward the bottom of the container, the blades 322 with both sides being flat can be arranged with one end away from the air outlet 210 tilted upward.

[0069] The blades 322 with both sides being flat are tilted so that the hot air and the horizontal air intake are staggered at a large angle, thereby enhancing the physical isolation effect of the hot air and the fresh air, and further improving the heat dissipation efficiency of the sound-absorbing louver 320. In particular, when the end of the blade 322 away from the air outlet 210 is tilted upward, that is, when the air is blown upward toward the bottom of the container, the noise propagates upward and is diffused and weakened in a large space, avoiding problems such as airflow reflection caused by the airflow directly blowing onto the relative container metal, directly eliminating the reflection effect of the noise, and greatly reducing the reflection noise between multiple energy storage devices.

[0070] Reference Figures 6 to 8 As shown, it can be understood that in the vertical direction, both sides of the blade 322 are convex curved surfaces. At this time, the cross-sectional shape of the blade 322 is elliptical.

[0071] Both sides of the blade 322 are set to be convex curved surfaces. When hot air flows on the surface of the blade 322, the curved surface can guide the flow of hot air, reduce the flow resistance of the hot air, and ensure the heat dissipation efficiency of the sound-absorbing louver 320.

[0072] In some embodiments, in the air outlet direction of the air outlet 210 , one end of the elliptical blade 322 that is horizontally away from the air outlet 210 is tilted upward or tilted downward.

[0073] The user can set the arrangement direction of the elliptical blades 322 according to actual conditions to adapt to different blowing requirements. For example, in the case of low flow resistance, slightly lower noise reduction requirements, and the wind blowing out parallel to the top of the container, the elliptical blades 322 can be arranged horizontally. In the case of low flow resistance, slightly lower noise reduction requirements, and the wind blowing out upward toward the top of the container, the end of the elliptical blade 322 away from the air outlet 210 can be tilted downward. In the case of low flow resistance, slightly lower noise reduction requirements, and the wind blowing out downward toward the bottom of the container, the end of the elliptical blade 322 away from the air outlet 210 can be tilted upward.

[0074] The elliptical blades 322 are tilted so that the hot air and the horizontal incoming air are staggered at a large angle, thereby enhancing the physical isolation effect of the hot air and the fresh air, and further improving the heat dissipation efficiency of the sound-absorbing louvers 320.

[0075] Reference Figures 9 to 12 As shown, it can be understood that in the vertical direction, one side of the blade 322 is a convex curved surface, and the other side is a concave curved surface. At this time, the cross-sectional shape of the blade 322 is crescent-shaped.

[0076] The cross section of the blade 322 is set to a crescent shape, and under the premise of ensuring that there is enough air outlet area between adjacent blades 322, the hot air is guided to blow out obliquely in the direction of the opening of the crescent-shaped blade 322. The user can set the arrangement direction of the crescent-shaped blade 322 according to actual conditions to adapt to different blowing requirements. For example, in the case of high noise reduction requirements, low flow resistance requirements, and the air outlet is blown downward toward the bottom of the container, the lower side of the blade 322 can be set to a concave curved surface, and the upper side of the blade 322 can be set to a convex curved surface, so that the cross section of the blade 322 is a crescent shape with the opening facing downward. In the case of high noise reduction requirements, low flow resistance requirements, and the air outlet is blown upward toward the top of the container, the upper side of the blade 322 can be set to a concave curved surface, and the lower side of the blade 322 can be set to a convex curved surface, so that the cross section of the blade 322 is a crescent shape with the opening facing upward.

[0077] The blades 322 are set to be crescent-shaped, so that the hot air and the horizontal incoming air are staggered at a large angle, thereby enhancing the physical isolation effect of the hot air and the fresh air, and further improving the heat dissipation efficiency of the sound-absorbing louver 320.

[0078] The user can set the arrangement direction of the crescent-shaped blades 322 according to actual conditions to meet different blowing requirements. For example, in the case where the noise reduction requirement is high, the flow resistance requirement is not high, and the air outlet is blown downward at a large angle toward the bottom of the container, the end of the crescent-shaped blade 322 away from the air outlet 210 can be tilted downward. In the case where the noise reduction requirement is high, the flow resistance requirement is not high, and the air outlet is blown upward at a large angle toward the bottom of the container, the end of the crescent-shaped blade 322 away from the air outlet 210 can be tilted upward.

[0079] On the premise that the crescent-shaped blades 322 guide the air to blow out at an angle, the crescent-shaped blades 322 are arranged at an angle to further increase the air outlet angle and enhance the noise reduction effect.

[0080] Reference Figures 13 to 16 As shown, it can be understood that in the vertical direction, one side of the blade 322 is a convex V-shaped surface, and the other side is a concave V-shaped surface. At this time, the cross-section of the blade 322 is V-shaped.

[0081] The cross section of the blade 322 is set to be V-shaped. Under the premise of ensuring that the structure of the blade 322 is simple, it is ensured that there is enough air outlet area between adjacent blades 322, and the hot air is guided to blow out obliquely in the direction of the opening of the V-shaped blade 322. The user can set the arrangement direction of the V-shaped blade 322 according to the actual situation to adapt to different blowing requirements. For example, in the face of a simple manufacturing process, high noise reduction requirements, and the wind blowing downward toward the bottom of the container, the lower side of the blade 322 can be set to a concave V-shaped surface, and the upper side of the blade 322 can be set to a convex V-shaped surface, so that the cross section of the blade 322 is a V-shaped opening facing downward. In the face of a simple manufacturing process, high noise reduction requirements, and the wind blowing upward toward the top of the container, the upper side of the blade 322 can be set to a concave V-shaped surface, and the lower side of the blade 322 can be set to a convex V-shaped surface, so that the cross section of the blade 322 is a V-shaped opening facing upward.

[0082] The blade 322 is set to a V shape so that the hot air and the horizontal air intake are staggered at a large angle, thereby enhancing the physical heat isolation effect between the hot air and the fresh air, further improving the heat dissipation efficiency of the sound-absorbing louver 320, simplifying the structure of the blade 322, and reducing the production cost of the blade 322.

[0083] The user can set the arrangement direction of the V-shaped blades 322 according to actual conditions to meet different blowing requirements. For example, in the case of simple manufacturing process, high noise reduction requirements, and the wind blowing out at a large angle and tilting downward toward the bottom of the container, the V-shaped blade 322 can be set with one end away from the air outlet 210 tilted downward. In the case of simple manufacturing process, high noise reduction requirements, and the wind blowing out at a large angle and tilting upward toward the bottom of the container, the V-shaped blade 322 can be set with one end away from the air outlet 210 tilted upward.

[0084] On the premise that the V-shaped blades 322 guide the air to blow out at an angle, the crescent V-shaped blades 322 are arranged at an angle to further increase the air outlet angle and enhance the noise reduction effect.

[0085] It is understandable that, in some embodiments, the air inlet and outlet surfaces of the heat dissipation cabinet 200 are in the same plane, that is, the air inlet 220 and the air outlet 210 of the heat dissipation cabinet 200 are located on the same side of the heat dissipation cabinet 200 (the air outlet 210 is usually located above the air inlet 220). In order to prevent the air outlet at the sound-absorbing louver 320 from being re-inhaled into the heat dissipation cabinet 200, this requires the blades 322 to be tilted in an orderly manner. At this time, in the vertical direction along the tilt direction of the end of the blade 322 away from the air outlet 210, the tilt angles of the multiple blades 322 increase successively, wherein the tilt angle of the blade 322 is the angle between the connecting line of the two ends of the blade 322 and the horizontal plane along the air outlet direction of the air outlet 210.

[0086] Specifically, the blades 322 of the muffler louver 320 are in a crescent or V shape with the opening facing downward, and when the end of the crescent or V-shaped blade 322 away from the air outlet 210 is tilted downward, in order to prevent the downward outlet air from the muffler louver 320 from being re-inhaled into the heat dissipation cabinet 200, the tilt angles of the multiple blades 322 increase in sequence along the tilt direction of the end of the blade 322 away from the air outlet 210 in the vertical direction (i.e., from top to bottom). The lower the position of the muffler louver 320 is, the greater the tilt angle of the blade 322 closer to the air inlet 220 is, and the greater the diffusion angle of the hot air closer to the air inlet 220 is, reducing the hot air gathering and preventing the hot air from being re-inhaled.

[0087] The blades 322 of the muffler louver 320 are in a crescent or V shape with the opening facing upward, and when the end of the crescent or V-shaped blade 322 away from the air outlet 210 is tilted upward, in order to prevent the downward outlet air from the muffler louver 320 from being re-inhaled into the heat dissipation cabinet 200, the tilt angles of the multiple blades 322 increase in sequence along the tilt direction of the end of the blade 322 away from the air outlet 210 in the vertical direction (i.e., from bottom to top). The more the position of the muffler louver 320 is upward, the greater the tilt angle of the blade 322 away from the air inlet 220, and the hot air quickly spreads on the top of the container, preventing the hot air from being re-inhaled.
