Airflow assembly and energy storage device

Abstract

An airflow assembly and an energy storage device. The airflow assembly comprises a first flow-through member, a second flow-through member, and a partition assembly. The first flow-through member is provided with a first flow-through opening. The second flow-through member is connected to the first flow-through member and a flow-through cavity is formed therebetween. The partition assembly is disposed between the first flow-through member and the second flow-through member, and divides the flow-through cavity into a first flow-through cavity and a second flow-through cavity arranged side by side. The first flow-through opening is communicated with the first flow-through cavity; the partition assembly is provided with a second flow-through opening, and the second flow-through opening is communicated with the second flow-through cavity; and external air is split when flowing through the airflow assembly, and flows out of the airflow assembly via the first flow-through cavity and the second flow-through cavity, respectively. The partition assembly divides the flow-through cavity into multiple spaces. When noise propagates in the airflow assembly, sound waves of the noise experience impedance mismatch due to sudden spatial changes, such that the sound waves of the noise are reflected continuously, causing the noise intensity to attenuate, thereby achieving a noise reduction effect.

[0060] Please refer to FIG. 1 and FIG. 2, the present application embodiment provides a kind of energy storage equipment 200, including fuselage 20 and wind passing assembly 100.

[0061] The machine body 20 is provided with a liquid cooling cabin 21, a battery cabin 22 and an electrical cabin 23 arranged in sequence along the longitudinal direction of the machine body 20, and the machine body 20 is also provided with a plurality of air outlets 24 and air inlets 25, and part of the air outlets 24 and the air inlets 25 are in communication with the liquid cooling cabin 21, and part of the air outlets 24 and the air inlets 25 are in communication with the electrical cabin 23.

[0062] Please refer to FIG. 3 and FIG. 4, each air passing assembly 100 is arranged on the corresponding air outlet 24 or air inlet 25. Among them, the gas in the machine body 20 can be discharged to the outside through the air passing assembly 100 arranged on the air outlet 24, and the outside gas can flow into the machine body 20 through the air passing assembly 100 arranged on the air inlet 25.

[0063] Specifically, please refer to FIG. 6 and FIG. 7, or please refer to FIG. 10 and FIG. 11, the air passing assembly 100 provided in the embodiment of the present application comprises a first flow piece 11, a second flow piece 12 and a separation assembly 13.

[0064] The first flow piece 11 is provided with a first flow port 112. The second flow piece 12 is in abutment with the first flow piece 11 and a flow cavity 10 is formed between the two. The separation assembly 13 is arranged between the first flow piece 11 and the second flow piece 12 and divides the flow cavity 10 into a first flow cavity 101 and a second flow cavity 102 arranged side by side.

[0065] Among them, the outside gas is in communication with the first flow cavity 101 through the first flow port 112; the separation assembly 13 is provided with a second flow port 131, and the outside gas is in communication with the second flow cavity 102 through the second flow port 131; the outside gas is divided when flowing through the air passing assembly 100 and flows out of the air passing assembly 100 through the first flow cavity 101 and the second flow cavity 102 respectively.

[0066] It can be understood that the process of the outside gas flowing through the air passing assembly 100 can be understood as the whole process of the outside gas flowing through the air passing assembly 100 from the air inlet surface of the air passing assembly 100 and flowing out of the air outlet surface of the air passing assembly 100. It can be understood that, since the air passing assembly 100 can be used as an air inlet assembly and an air outlet assembly, the corresponding air inlet surface and air outlet surface of the air passing assembly 100 when used as an air inlet assembly can be different from the corresponding air inlet surface and air outlet surface of the air passing assembly 100 when used as an air outlet assembly.

[0067] Specifically, please refer to FIG. 5 and FIG. 6, in the case that the air passing assembly 100 is used as an air inlet assembly, one side of the second flow piece 12 is the air inlet surface of the air inlet assembly, and one side of the first flow piece 11 is the air outlet surface of the air inlet assembly. Please refer to FIG. 9 and FIG. 10, in the case that the air passing assembly 100 is used as an air outlet assembly, one side of the first flow port 112 of the first flow piece 11 is the air inlet surface of the air outlet assembly, and one side of the second flow piece 12 is the air outlet surface of the air outlet assembly.

[0068] It can be understood that the air passing assembly 100 provided by the embodiments of the present application can divide the flow passing cavity 10 into multiple spaces through the partition assembly 13, wherein a part of the gas enters and then passes out through the first flow passing cavity 101, and another part of the gas enters and then passes out through the second flow passing cavity 102. In this way, since the gas passes through two different flow passing cavities, when the noise passes through the air passing assembly 100, the noise sound waves will also be reflected due to the sudden change of the space, thereby causing the attenuation of the noise intensity and achieving the noise reduction effect.

[0069] The specific styles of the first flow passing member 11 and the second flow passing member 12 are not limited.

[0070] In some embodiments, the first flow passing member is a first plate body provided with a first flow passing opening, and the second flow passing member includes a second plate body and a side plate, the side plate is arranged around the edge of the second plate body, and the first plate body is connected with the side plate to jointly enclose the flow passing cavity. Specifically, referring to FIGS. 6 and 10, the first plate body 111 is provided with a first flow passing opening 112 to form the first flow passing member 11, the second plate body 121 and the side plate 122 constitute the second flow passing member 12, the side plate 122 is arranged around the edge of the second plate body 121, and the first plate body 111 is butted with the side plate 122 to jointly enclose the flow passing cavity 10. Specifically, the first plate body 111 and the side plate 122 can be integrally formed or connected as separate components at a later stage.

[0071] In other embodiments, the first flow passing member includes a first plate body and a side plate, the first plate body is provided with a first flow passing opening, and the side plate is arranged around the edge of the first plate body, and the second flow passing member includes a second plate body, and the second plate body is connected with the side plate to jointly enclose the flow passing cavity. This embodiment is not shown in the figure, but it can be understood in combination with FIGS. 6 and 10 that the first plate body 111 and the side plate 122 constitute the first flow passing member 11, the first plate body 111 is provided with a first flow passing opening 112, and the side plate 122 is arranged around the edge of the first plate body 111. Specifically, the first plate body 111 and the side plate 122 can be integrally formed or connected as separate components at a later stage. The second flow passing member 12 includes a second plate body 121, and the second plate body 121 is butted with the side plate 122 to jointly enclose the flow passing cavity 10.

[0072] In some embodiments, referring to FIGS. 6 and 10, the air passing assembly 100 further includes a first guide member 14, a second guide member 15, and a third guide member 16.

[0073] The first guide member 14 is arranged outside the first flow passing member 11 and around the first flow passing opening 112, the second guide member 15 is arranged inside the second flow passing member 12, and the third guide member 16 is arranged on one side of the partition assembly 13 and encloses the second flow passing opening 131.

[0074] It should be noted that in the present application, the side of the first flow member 11 and the second flow member 12 facing the flow cavity 10 is the inner side, and correspondingly, the side of the first flow member 11 and the second flow member 12 facing away from the flow cavity 10 is the outer side.

[0075] When the partition assembly 13 is arranged in the flow cavity 10, referring to FIGS. 5 and 9, the first guide member 14 of the first flow member 11 is arranged around the outer periphery of the third guide member 16 of the partition assembly 13, and a first flow space is formed between the first guide member 14 and the third guide member 16. The third guide member 16 of the partition assembly 13 is arranged around the outer periphery of the second guide member 15 of the second flow member 12, and a second flow space is formed between the second guide member 15 and the third guide member 16.

[0076] It can be understood that the flow space refers to a space through which gas can flow into or out of the air flow assembly 100. Specifically, when gas flows into the air flow assembly through the flow space, the gas can enter the air flow assembly 100 from the first flow port 112 and enter the first flow cavity 101 through the first flow space, and the gas can also enter the air flow assembly 100 from the second flow port 131 and enter the second flow cavity 102 through the second flow space.

[0077] Exemplarily, referring to FIG. 7, when the air flow assembly 100 is used as an air inlet assembly, the external gas will be divided after flowing into the air flow assembly 100, and part of the divided gas will enter the first flow cavity 101 (as shown by the gray arrows), and then flow into the fuselage 20 through the first flow space and the first flow port 112; part of the divided gas will enter the second flow cavity 102 (as shown by the black arrows),

[0078] and then flow into the fuselage 20 through the second flow space and the second flow port 131.

[0079] Similarly, when the gas flows out of the air flow assembly 100 through the flow space, the gas can flow out of the air flow assembly 100 through the first flow port 112 after flowing through the first flow cavity 101 and then flowing through the first flow space, and the gas can also flow out of the air flow assembly 100 through the second flow port 131 after flowing through the second flow cavity 102 and then flowing through the second flow space.

[0080] Exemplarily, referring to FIG. 11, when the air flow assembly 100 is used as an air outlet assembly, the gas in the fuselage 20 will be divided when entering the air flow assembly 100, wherein part of the divided gas will flow into the air flow assembly 100 through the first flow port 112 and the first flow space and then be discharged to the outside (as shown by the gray arrows); part of the divided gas will flow into the air flow assembly 100 through the second flow port 131 and the second flow space and then be discharged to the outside (as shown by the black arrows).

[0081] It can be understood that, in the direction from the center of the first flow port 112 to the center of the second flow port 131, the projection range of the second flow port 131 is located in the projection range of the first flow port 112, that is, the size of the first flow port 112 is greater than the size of the second flow port 131.

[0082] In the embodiment, since there is a change in the shape or size between the first flow space and the first flow cavity 101, and between the second flow space and the second flow cavity 102, when the noise flows in the air passing assembly 100, it will pass through spaces with different shapes or sizes. The noise sound wave will be mismatched due to the sudden change of the space, which will cause the noise sound wave to be reflected continuously, thereby causing the attenuation of the noise intensity, and achieving the noise reduction effect. At the same time, the air passing assembly 100 can increase the noise reduction area and the noise propagation distance, thereby effectively preventing the noise from being transmitted outward, so as to improve the noise reduction effect.

[0083] In some embodiments, a plurality of first flow holes 123 are formed in the side plate 122. External gas can flow out of the air passing assembly 100 through the first flow port 112, the first flow cavity 101 and part of the first flow holes 123; external gas can also flow out of the air passing assembly 100 through the second flow port 131, the second flow cavity 102 and part of the first flow holes 123. The first flow cavity 101 and the second flow cavity 102 are in communication with the external gas through the first flow holes 123 formed in the side plate 122. Optionally, the first flow holes 123 can be uniformly distributed on the side plate, so that the first flow cavity 101 is in communication with the external gas through part of the first flow holes 123, and the second flow cavity 102 is in communication with the external gas through another part of the first flow holes 123.

[0084] It can be understood that in this case, the above-mentioned air passing assembly 100 can be used as an air outlet assembly, as shown in FIGS. 9 and 10, the side plate 122 is provided with first flow holes 123, and the first flow holes 123 are used as air outlets of the air inlet assembly.

[0085] For example, as shown in FIG. 11, when the gas in the body enters the air outlet assembly, it will be divided, and part of the gas (as shown by the gray arrows) will pass through the first flow port 112, the first flow space and the first flow cavity 101 in turn, and finally flow out of the air outlet assembly through part of the first flow holes 123. Part of the gas (as shown by the black arrows) will pass through the second flow port 131, the second flow space and the second flow cavity 102 in turn, and finally flow out of the air outlet assembly through another part of the first flow holes 123.

[0086] It should be noted that in the process of sound passing through the air outlet assembly with such a structure, the sound first enters the first flow cavity 101 and the second flow cavity 102 through the first flow port 112 and the second flow port 131 respectively. The sound entering the first flow cavity 101 is weakened by the blocking of the partition assembly 13, and after weakening, the sound is transmitted to the side plate 122 under the action of the partition assembly 13, and then is weakened again by the blocking of the side plate 122, and finally is transmitted to the outside from part of the first flow hole 123. The sound entering the second flow cavity 102 is weakened by the blocking of the second plate body 121, and after weakening, the sound is transmitted to the side plate 122 under the action of the partition assembly 13, and then is weakened again by the blocking of the side plate 122, and finally is transmitted to the outside from part of the first flow hole 123. In this way, the sound entering the air outlet assembly with such a structure is reflected multiple times, thereby causing the attenuation of noise intensity and achieving the noise reduction effect.

[0087] Exemplarily, as shown in FIG. 12, the propagation path of the sound entering the first flow cavity 101 through the first flow port 112 is shown by the gray arrow, and the propagation path of the sound entering the second flow cavity 102 through the second flow port 131 is shown by the black arrow.

[0088] In the embodiment of the present application, a plurality of first flow holes 123 are formed on the side plate 122 of the air flow assembly 100, and in the case of the air flow assembly 100 as an air outlet assembly, the gas separated by the first flow port 112 and the second flow port 131 flows into the first flow cavity 101 and the second flow cavity 102 respectively. The gas flowing into the first flow cavity 101 flows out to the outside through part of the first flow hole 123 communicating with the first flow cavity 101, and the gas flowing into the second flow cavity 102 flows out to the outside through part of the first flow hole 123 communicating with the second flow cavity 102. In this way, in the case of the air flow assembly 100 as an air outlet assembly, the energy storage device 200 can have sufficient exhaust rate and exhaust volume to effectively enhance the heat dissipation effect of the energy storage device 200.

[0089] In some embodiments, when a plurality of first flow holes are formed on the side plate of the air flow assembly, the air flow assembly is preferentially used as an air outlet assembly. When the air flow assembly is used as an air outlet assembly, the first flow port and the second flow port of the air flow assembly are in communication with the air outlet of the energy storage device to face the inside of the energy storage device, and the bottom plate of the second flow member faces the outside of the energy storage device. Specifically, the first flow hole on the side plate is at least partially located outside the energy storage device. Exemplarily, as shown in FIG. 4, the air outlet assembly is arranged at the air outlet 24, and all the first flow holes are located outside the energy storage device.

[0090] Optionally, when the air passing assembly 100 is an air outlet assembly, the air outlet assembly can be installed on the top side of the energy storage device. For example, referring to FIG. 1 and FIG. 2, the top surface of the energy storage device 200 is provided with an air outlet 24, and the air outlet side air passing assembly 100 is arranged on the air outlet 24 of the energy storage device 200. In this way, since all the first flow holes 123 are arranged on the side plate 122, it can effectively prevent rainwater and foreign matter from directly entering the energy storage device 200.

[0091] In some embodiments, the second plate body is provided with a plurality of first flow holes, and the partition assembly is provided with a second flow hole communicating the first flow cavity and the second flow cavity.

[0092] In this way, the external air can pass through the first flow hole, part of the second flow cavity, the second flow hole, the first flow cavity, and the first flow port to flow out of the air passing assembly; the external air can pass through the first flow hole, the second flow cavity, and the second flow port to flow out of the air passing assembly. The second flow cavity is in communication with the external air through the second flow hole arranged on the second plate body.

[0093] It can be understood that in this case, the above-mentioned air passing assembly can be an air inlet assembly. For example, referring to FIG. 5 and FIG. 6, the second plate body is provided with a plurality of first flow holes 123, so that the flow cavity can be in communication with the external air through the first flow holes 123. Optionally, the first flow holes 123 can be arranged around the second plate body, rather than being arranged on the second plate body. In this way, the air inlet amount can be controlled to a certain extent.

[0094] It can be understood that when the air passing assembly is an air inlet assembly, the first flow hole is arranged on the second plate body, and when the air passing assembly is an air outlet assembly, the first flow hole is arranged on the side plate. The positions of the two first flow ports are different.

[0095] The partition assembly 13 is provided with a second flow hole 132. Specifically, the second flow hole 132 is a plurality of second flow holes which can be uniformly arranged on the partition assembly to communicate the first flow cavity 101 and the second flow cavity 102. The side plate 122 is provided with a first flow hole 123, which serves as an air outlet of the air inlet assembly. Optionally, the first flow holes can be uniformly distributed on the side plate, so that the first flow cavity is in communication with the external air through part of the first flow holes, and the second flow cavity is in communication with the external air through another part of the first flow holes.

[0096] Exemplarily, as shown in FIG. 7, the gas outside the fuselage enters the air inlet assembly through the first flow hole 123, and after entering the air inlet assembly, the gas is divided into two parts. One part of the gas (as shown by the gray arrows) passes through the second flow cavity 102, the first flow cavity 101 (from the second flow cavity 102 to the first flow cavity 101 through the second flow hole), the first flow space, and the first flow port 112 in sequence, and finally flows out of the air inlet assembly through the first flow port 112 and enters the inside of the energy storage device. The other part of the gas (as shown by the black arrows) passes through the second flow cavity 102, the second flow space, and the second flow port 131 in sequence, and finally flows out of the air inlet assembly through the second flow port 131 and enters the inside of the energy storage device.

[0097] It should be noted that in the process of sound passing through the air outlet assembly with such a structure, the sound first enters the first flow cavity 101 and the second flow cavity 102 through the first flow port 112 and the second flow port 131, respectively. The sound entering the first flow cavity 101 is blocked by the partition assembly 13 and attenuated, and the attenuated sound propagates to the second flow cavity 102 through the second flow hole 132 of the partition assembly 13, and is then blocked by the second plate body 121 and attenuated again, and finally transmitted to the outside from the first flow hole 123 of the second plate body 121. The sound entering the second flow cavity 102 is blocked by the second plate body 121 and attenuated, and then transmitted to the outside from part of the first flow holes 123. In this way, the sound entering the air outlet assembly with such a structure is reflected multiple times, thereby causing the attenuation of noise intensity and achieving the noise reduction effect. At the same time, the sound entering the first flow cavity 101 through the first flow port 112 reenters the second flow cavity 102, so that the noise sound wave flows through spaces with different shapes or sizes, and the noise sound wave appears impedance mismatch due to the sudden change of the space, which causes the noise sound wave to reflect continuously, thereby causing the attenuation of noise intensity and achieving the noise reduction effect.

[0098] Exemplarily, as shown in FIG. 8, the propagation path of the sound entering the first flow cavity 101 through the first flow port 112 is shown by the gray arrows, and the propagation path of the sound entering the second flow cavity 102 through the second flow port 131 is shown by the black arrows.

[0099] In some embodiments, when the second plate body of the air passing assembly and the partition assembly are respectively provided with a plurality of flow holes, the air passing assembly is used as an air inlet assembly. When the air passing assembly is used as the air inlet assembly, the first flow port and the second flow port of the air passing assembly are both in communication with the air inlet of the energy storage device 200 to face the inside of the energy storage device, and the bottom plate of the second flow member faces the outside of the energy storage device. Specifically, the first flow holes on the second bottom plate are at least partially located on the outside of the energy storage device. For example, as shown in FIG. 4, the air inlet assembly is arranged at the air inlet 25, and specifically, the air inlet assembly does not protrude from the outer surface of the energy storage device, but the first flow holes of the air inlet assembly can all contact the external gas.

[0100] Optionally, when the air passing assembly 100 is used as the air inlet assembly, the air inlet assembly can be arranged on the side surface of the energy storage device. For example, as shown in FIGS. 1 and 2, the side surface of the energy storage device 200 is provided with an air inlet 25, and the air inlet assembly 100 is arranged on the air inlet 25 of the energy storage device 200. In this way, the foreign matter and dust can be effectively prevented from entering the energy storage device 200 through the first flow holes 123.

[0101] In some embodiments, as shown in FIGS. 8 and 11, the first plate body 111, the second plate body 121 and the partition assembly 13 are all recessed towards one side.

[0102] It should be noted that in the present application, the first plate body 111, the second plate body 121 and the partition assembly 13 are all recessed towards the direction in which the second flow member 12 points to the first flow member 11. In this way, the first plate body 111, the second plate body 121 and the partition assembly 13 all form a funnel-shaped structure, so as to effectively guide the airflow flowing in the first flow cavity 101 and the second flow cavity 102, and effectively reduce the air resistance, so as to ensure the smooth flow of the airflow and the heat dissipation effect of the energy storage device 200. Meanwhile, the recess of the first plate body 111, the second plate body 121 and the partition assembly 13 can increase the surface area thereof, so as to increase the area of the first plate body 111, the second plate body 121 and the partition assembly 13 that can contact the sound to reflect the sound, so as to effectively enhance the noise reduction effect of the air passing assembly.

[0103] In some embodiments, as shown in FIGS. 8 and 11, the first flow port 112 is located at the center of the recess of the first plate body 111, and the second flow port 131 is located at the center of the recess of the partition assembly 13. In this way, the production and assembly of the first flow member 11 and the partition assembly 13 can be facilitated.

[0104] In some embodiments, as shown in FIGS. 8 and 11, the first plate body 111 and the first guide member 14 are connected in a circular arc transition, the second plate body 121 and the second guide member 15 are connected in a circular arc transition, and the partition assembly 13 and the third guide member 16 are connected in a circular arc transition.

[0105] It should be noted that the arc transition refers to a smaller arc radius transition at the intersection of the part surface in the process of manufacturing mechanical parts, in order to improve the strength and manufacturing process of the part, and other structural requirements, so as to improve the process performance of the part. This transition method helps to improve the strength and stiffness of the product, making the product structure relatively simple and smooth.

[0106] It can be understood that under the guidance of the first guide 14 and the third guide 16, the airflow enters the first flow space and the first flow port 112 into the first flow cavity 101, and then changes direction under the guidance of the separation assembly 13. The arc transition connection between the separation assembly 13 and the third guide 16 can effectively reduce the wind resistance of the airflow from the third guide 16 to the separation assembly 13, so as to ensure smooth flow of the airflow. Similarly, under the guidance of the second guide 15 and the third guide 16, the airflow enters the second flow space and the second flow port 131 into the second flow cavity 102, and then changes direction under the guidance of the second plate body 121. The arc transition connection between the second plate body 121 and the second guide 15 can effectively reduce the wind resistance of the airflow from the second guide 15 to the second plate body 121, so as to ensure smooth flow of the airflow.

[0107] In some embodiments, the air passing assembly further comprises a first separation part and a second separation part.

[0108] The first separation part is arranged on the separation assembly and is arranged at intervals around the circumference of the third guide.

[0109] The second separation part is arranged on the second flow member and is arranged at intervals around the circumference of the second guide.

[0110] Wherein, in the case that the separation assembly is arranged in the flow cavity, a first flow sub-cavity is formed between each adjacent two first separation parts, and all the first flow sub-cavities are in communication with the first flow port. A second noise reduction sub-cavity is formed between each adjacent two second separation parts, and all the second noise reduction sub-cavities are in communication with the second flow port.

[0111] It can be understood that the first separation part can be multiple, and the multiple first separation parts are connected between the outer peripheral edge of the separation assembly and the third guide. The second separation part can also be multiple, and the multiple second separation parts are connected between the outer peripheral edge of the second flow member and the second guide.

[0112] It can be understood that in the case that the separation assembly 13 is arranged in the flow cavity 10, the first separation part is located between the first flow member 11 and the separation assembly, and a first flow sub-cavity is formed between each adjacent two first separation parts 17, that is, each first separation part 17 can divide the first flow cavity 101 between the first flow member 11 and the separation assembly into a plurality of first flow sub-cavities.

[0113] Correspondingly, the second partition part 18 is located between the second flow passage part 12 and the partition assembly 13, and each adjacent two second partition parts 18 form a second flow sub-cavity, so that each second partition part 18 can divide the second flow cavity 102 formed between the second flow passage part 12 and the partition assembly 13 into a plurality of first flow sub-cavities.

[0114] That is, the external gas entering the first flow cavity 101 is further divided into each first flow sub-cavity, and the external gas entering the second flow cavity 102 is further divided into each second flow sub-cavity.

[0115] In this way, by arranging the first partition part 17 and the second partition part 18, the space in the flow cavity 10 can be further divided to increase the complexity of the space change in the process of the airflow flowing in the flow assembly 100, and the noise propagation distance is effectively increased, thereby further improving the noise reduction effect.

[0116] In some embodiments, referring to FIGS. 15 and 16, in the case where the partition assembly 13 includes at least two partition pieces, each partition piece is arranged to be spaced apart from each other, and the second flow cavity 102 includes at least two flow units 103, each adjacent two partition pieces, and the second flow passage part 12 and the partition piece adjacent thereto form a second flow unit 1032, and the first flow passage part 11 and the partition piece adjacent thereto form the first flow cavity 101.

[0117] Each partition piece is provided with a second flow port 131, and each second flow port 131 is in communication with the corresponding second flow sub-cavity.

[0118] It can be understood that the specific number of partition pieces is not limited. For ease of understanding, the writing of the embodiments in the present application is based on the case where the partition assembly 13 includes two partition pieces.

[0119] Specifically, referring to FIG. 15 and FIG. 16, the partition piece close to the first flow passage 11 is defined as the first partition piece 133, and the partition piece close to the second flow passage 12 is defined as the second partition piece 134. The first flow passage 11 and the first partition piece 133 form the first flow cavity 101. The first partition piece 133 and the second partition piece 134, and the second flow passage 12 and the second partition piece 134 form the flow unit 103. The flow unit 103 formed between the first partition piece 133 and the second partition piece 134 is defined as the first flow unit 1031, and the flow unit 103 formed between the second flow passage 12 and the second partition piece 134 is defined as the second flow unit 1032. In this way, the first flow cavity 101 is in communication with the first flow port 112 on the first flow passage 11. The first flow unit 1031 is in communication with the second flow port 131 on the first partition piece 133. The second flow unit 1032 is in communication with the second flow port 131 on the second partition piece 134.

[0120] When the air passing assembly 100 is used as an air inlet assembly, the side of the second flow passage is the air inlet surface of the air inlet assembly, and the side of the first flow passage 11 is the air outlet surface of the air inlet assembly. When the air passing assembly is used as an air outlet assembly, the side of the first flow port of the first flow passage is the air inlet surface of the air outlet assembly, and the side of the second flow passage is the air outlet surface of the air outlet assembly.

[0121] It can be understood that the air passing assembly provided by the embodiment of the present application can divide the flow cavity into the first flow cavity, the first flow unit and the second flow unit through the first partition piece and the second partition piece. A part of the air inlet air passes through the first flow cavity to be outlet air, a part of the air inlet air passes through the first flow unit to be outlet air, and another part of the air inlet air passes through the second flow unit to be outlet air. In this way, since the air passes through two different flow cavities to circulate, the noise sound wave will also be reflected due to the sudden change of space when the noise sound wave circulates in the air passing assembly, thereby causing the attenuation of the noise intensity and achieving the noise reduction effect.

[0122] Specifically, in the case that the air passing assembly is an air inlet assembly, a plurality of first flow holes are formed on the second plate body, and the first partition piece is provided with second flow holes communicating the first flow cavity and the first flow unit; the second partition piece is provided with second flow holes communicating the first flow unit and the second flow unit. Wherein, the external air can pass through the first flow holes, part of the second flow unit, the second flow holes on the second partition piece, part of the first flow unit, the second flow holes on the first partition piece, the first flow cavity and the first flow port to flow out of the air passing assembly; the external air can pass through the first flow holes, part of the second flow unit, the second flow holes on the second partition piece, part of the first flow unit and the second flow holes on the first partition piece to flow out of the air passing assembly; the external air can pass through the first flow holes, the second flow unit and the second flow holes on the second partition piece to flow out of the air passing assembly.

[0123] It should be noted that in the process of sound passing through the air outlet assembly with such a structure, the sound first enters the first flow cavity, the first flow unit and the second flow unit through the first flow port, the second flow port on the first partition piece and the second flow port on the second partition piece respectively. Among them, the sound entering the first flow cavity is blocked by the first partition piece and attenuated, the sound after attenuation propagates into the first flow unit through the second flow hole on the first partition piece, and then is blocked again by the second partition piece and attenuated again, the sound after attenuation again propagates into the second flow unit through the second flow hole on the second partition piece, and then is blocked again by the second plate body and attenuated again, and finally the sound after attenuation again is transmitted to the outside from part of the first flow holes; the sound entering the first flow unit is blocked by the second partition piece and attenuated, and the sound after attenuation propagates into the second flow unit through the second flow hole on the second partition piece, and then is blocked again by the second plate body and attenuated again, and finally the sound after attenuation again is transmitted to the outside from part of the first flow holes; the sound entering the second flow unit is blocked by the second plate body and attenuated, and then transmitted to the outside from part of the first flow holes. In this way, the sound entering the air outlet assembly with such a structure is reflected multiple times, thereby causing the attenuation of noise intensity and achieving the noise reduction effect. At the same time, the sound entering the first flow cavity through the first flow port enters the first flow unit and the second flow unit in turn, and the sound entering the first flow unit through the second flow port of the first partition piece enters the second flow unit again, and these two flow paths can make the noise sound wave flow through spaces with different shapes or sizes, and the noise sound wave will appear impedance mismatching due to the sudden change of space, thereby causing the noise sound wave to reflect continuously, thereby causing the attenuation of noise intensity and achieving the noise reduction effect.

[0124] In the case that the air passing assembly 100 is an air outlet assembly, please refer to FIG. 15, the air in the machine body 20 will be divided into three parts when entering the air passing assembly 100, one part of the air will flow into the air passing assembly 100 through the first air passing port 112 and then flow out of the air passing assembly, another part of the air will flow into the first air passing unit 1031 through the second air passing port 131 on the first partition 133 and then flow out of the air passing assembly, and the rest of the air will flow into the second air passing unit 1032 through the second air passing port 131 on the second partition 134 and then flow out of the air passing assembly.

[0125] Specifically, in the case that the air passing assembly 100 is an air outlet assembly, a plurality of first air passing holes are formed on the side plate. The air outside the air passing assembly can flow out of the air passing assembly through the first air passing port 112, the first air passing cavity and part of the first air passing holes; the air outside the air passing assembly can also flow out of the air passing assembly through the second air passing port 131 on the first partition 133, the first air passing unit 1031 and part of the first air passing holes; and the air outside the air passing assembly can also flow out of the air passing assembly through the second air passing port 131 on the second partition 134, the second air passing unit 1032 and part of the first air passing holes.

[0126] Exemplarily, as shown in FIG. 15, the air in the machine body will be divided into three parts when entering the air outlet assembly, one part of the air (as shown by the gray arrows) will flow into the air outlet assembly through the first air passing port 112, the first air passing space and the first air passing cavity 101, and then flow out of the air outlet assembly through part of the first air passing holes 123; another part of the air (as shown by the black arrows adjacent to the aforementioned gray arrows) will flow into the air outlet assembly through the second air passing port 131 on the first partition 133, the second air passing space and the first air passing unit 1031, and then flow out of the air outlet assembly through another part of the first air passing holes 123; and the rest of the air (as shown by the black arrows spaced from the aforementioned gray arrows) will flow into the air outlet assembly through the second air passing port 131 on the second partition 134, the second air passing space and the second air passing unit 1032, and then flow out of the air outlet assembly through another part of the first air passing holes 123.

[0127] It should be noted that in the process of sound passing through the air outlet assembly with such a structure, the sound first enters the first flow cavity 101, the first flow unit 1031 and the second flow unit 1032 through the first flow port 112, the second flow port 131 on the first partition 133 and the second flow port 131 on the second partition 134 respectively. Among them, the sound entering the first flow cavity 101 is weakened by the first partition 133, and after weakening, the sound is transmitted to the side plate 122 under the action of the first partition 133, and then is weakened again by the side plate 122, and finally is transmitted to the outside from part of the first flow hole 123; the sound entering the first flow unit 1031 is weakened by the second partition 134, and after weakening, the sound is transmitted to the side plate 122 under the action of the second partition 134, and then is weakened again by the side plate 122, and finally is transmitted to the outside from part of the first flow hole 123; the sound entering the second flow unit 1032 is weakened by the second plate body 121, and after weakening, the sound is transmitted to the side plate 122 under the action of the partition assembly 13, and then is weakened again by the side plate 122, and finally is transmitted to the outside from part of the first flow hole 123. In this way, the sound entering the air outlet assembly with such a structure will be reflected multiple times, thereby causing the attenuation of noise intensity and achieving the noise reduction effect.

[0128] Exemplarily, as shown in FIG. 16, the propagation path of the sound entering the first flow cavity 101 through the first flow port 112 is shown by the gray arrow, the propagation path of the sound entering the first flow unit 1021 through the second flow port 131 on the first partition 133 is shown by the black arrow adjacent to the aforementioned gray arrow, and the propagation path of the sound entering the second flow unit 1032 through the second flow port 131 on the second partition 134 is shown by the black arrow spaced from the aforementioned gray arrow.

[0129] It can be understood that the partition assembly provided by the embodiments of the present application can further divide the space in the flow cavity 10 through multiple partitions to increase the complexity of the space change in the process of airflow flowing through the air outlet assembly 100, effectively increase the noise reduction area and noise propagation distance, and further improve the noise reduction effect.

[0130] In some embodiments, not shown, the air outlet assembly 100 further comprises a filler, and the filler is acoustic cotton.

[0131] It can be understood that the acoustic cotton can absorb the noise in the airflow, thereby further enhancing the noise reduction effect of the air outlet assembly 100.

[0132] The specific arrangement position of the acoustic cotton is not limited. In some embodiments, not shown, the acoustic cotton is filled in at least one of the first flow cavity 101 and the second flow cavity 102.

[0133] It can be understood that the user can fill the sound-absorbing cotton into the air flow assembly 100 according to actual needs. In an embodiment, the sound-absorbing cotton can be filled into the first air flow cavity 101 and the second air flow cavity 102 at the same time, so as to further enhance the noise reduction effect of the air flow assembly 100. In another embodiment, the sound-absorbing cotton is filled into any one of the first air flow cavity 101 and the second air flow cavity 102. In yet another embodiment, if the separation assembly 13 includes two separators, the sound-absorbing cotton can be filled into the first air flow cavity 101, the first air flow unit 1031 and the second air flow unit 1032 at the same time, or the sound-absorbing cotton is filled into any one of the first air flow cavity 101, the first air flow unit 1031 and the second air flow unit 1032, or the sound-absorbing cotton is filled into any two of the first air flow cavity 101, the first air flow unit 1031 and the second air flow unit 1032 at the same time.
