It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

A feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0052] Furthermore, the illustrative expressions of the terms used in this specification do not necessarily refer to the same embodiments or implementations. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0053] Electrical equipment, such as inverters, is equipped with a heat dissipation system that uses a fluid-driven structure to drive fluid to flow in from the inlet and out from the outlet, thereby achieving heat dissipation for the electrical equipment.

[0054] In related technologies, to reduce the possibility of external foreign objects such as lint entering the equipment, a filter structure is usually installed at the inlet. However, this arrangement may affect the fluid flow rate. In particular, with prolonged use, the filter structure may become partially clogged by lint or other debris, further reducing the fluid flow rate and affecting the performance of the heat dissipation system. Without a filter structure, foreign objects may enter the equipment, affecting its performance. The filter structures in related technologies struggle to simultaneously meet both filtration requirements and fluid flow rate requirements.

[0055] To address the problems existing in the aforementioned related technologies, the first aspect of this embodiment provides a filter box structure, which includes a box body 1. The box body 1 has an outlet end 102 and a plurality of inlet ends 101, and the outlet end 102 is connected to at least two inlet ends 101 respectively to form a heat dissipation air duct. A filter structure 16 is arranged in any heat dissipation air duct, and a plurality of filter structures 16 are arranged sequentially along the airflow direction in at least one heat dissipation air duct.

[0056] Specifically, the number of heat dissipation ducts is the same as the number of inlet 101s. Each heat dissipation duct corresponds to a filtration path, and each filtration path is equipped with a filter structure 16. At least one filtration path has multiple filter structures 16 arranged sequentially. The filtration path can be referenced. Figure 2 , Figure 4 and Figure 12 The thick solid line in the image can be interpreted as the direction of fluid flow, with the arrow pointing in that direction.

[0057] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure after the filter box structure and the fluid drive structure 2 are connected in the first embodiment of this disclosure; Figure 2 for Figure 1 A schematic cross-sectional view at section AA.

[0058] It should be understood that the box body 1 is typically formed by the enclosure of multiple structural components, such as plates, etc. Figure 1 and Figure 2 As shown, in the first embodiment of this disclosure, the box body 1 can be formed by multiple plates to create a relatively complete box structure. For example, the box body 1 includes a first plate 11, a second plate 12, a third plate 13, a fourth plate 14, and a fifth plate 15. The first plate 11 and the third plate 13 are arranged opposite each other, the second plate 12 and the fifth plate 15 are arranged opposite each other, and the two fourth plates 14 are arranged opposite each other. The first plate 11, the second plate 12, the third plate 13, the fifth plate 15, and the two fourth plates 14 enclose a relatively complete box structure. On this basis, an inlet end 101, an outlet end 102, and a filter structure 16 are further formed. Of course, it is not limited to this, and will be described in conjunction with specific embodiments later.

[0059] The specific structure of filter structure 16 is not intended to be limiting, and will be illustrated later.

[0060] In an exemplary embodiment, the outlet end 102 of the filter housing structure is connected to the inlet end of the fluid drive structure 2, for example, the two can be directly connected or connected via a pipeline. For any path, under the driving action of the fluid drive structure 2, fluid flows from the inlet end 101 of the housing body 1 into the inner cavity of the housing body 1 and flows out from the outlet end 102 of the housing body 1. During this process, some foreign matter is filtered by the filter structure 16.

[0061] Thus, in this embodiment, when the outlet end 102 of the filter box structure 1 is connected to one end of the inlet of the fluid drive structure 2, since the outlet end 102 is connected to at least two inlet ends 101 respectively to form a heat dissipation air duct, and each heat dissipation air duct is provided with a filter structure 16, under the driving action of the fluid drive structure 2, at least two inlet ends 101 can be used for fluid entry, and at least two heat dissipation air ducts can be used for fluid filtration and passage. Even if at least one heat dissipation air duct is provided with multiple filter structures 16 in sequence, the fluid flow rate requirement can be guaranteed. Thus, the filtration requirement and fluid entry requirement of the heat dissipation system with the filter box structure can be taken into account, ensuring the performance of the heat dissipation system with the filter box structure.

[0062] Optionally, the box body 1 has a plurality of plates; at least one of the plurality of plates is formed with a filter structure 16, and an outlet end 102 or an inlet end 101 is formed through the filter structure 16.

[0063] like Figure 2 As shown, by way of example, the plurality of filter structures 16 include a first filter structure 161, a second filter structure 162 and a third filter structure 163; the first filter structure 161, the second filter structure 162 and the third filter structure 163 are respectively provided for the first inlet end 101a, the second inlet end 101b and the outlet end 102.

[0064] For example, a first filter structure 161 is formed on a first plate 11 and forms a first inlet end 101a; a second filter structure 162 is formed on a second plate 12 and forms a second inlet end 101b; and a third filter structure 163 is formed on a fifth plate 15 and forms an outlet end 102.

[0065] Of course, it should be understood that it is not limited to this. For example, the filter structure 16 may not be formed on the plate, but may be arranged separately, as will be illustrated later.

[0066] In this way, the plate can be used to form a filter structure 16, which can reduce the structural complexity of the filter box structure, making the structure simple and highly practical.

[0067] Optionally, the box body 1 has multiple plates, which enclose an open opening 17.

[0068] like Figures 3 to 11 As shown, Figure 3 This is a schematic diagram of the structure after the filter box structure and the fluid drive structure 2 are connected in the second embodiment of this disclosure; Figure 4 for Figure 3 A cross-sectional view at section BB; Figure 5 for Figure 3 Schematic diagram of the cross section at the middle CC section; Figure 6 for Figure 5 A magnified view of a portion of point A in the middle; Figure 7 for Figure 5 A magnified view of a portion of point B in the middle; Figure 8 for Figure 3 Schematic diagram of the cross section at the DD section; Figure 9 for Figure 8 A magnified view of a portion of point C in the middle; Figure 10 for Figure 3 A schematic diagram of the exploded structure corresponding to the structure shown; Figure 11 for Figure 3 The diagram shows another exploded view of the structure shown. Compared to the first embodiment, the filter box body 1 of the second embodiment does not have a fifth plate 15, thus forming an opening 17 at the position corresponding to the fifth plate 15.

[0069] Optionally, a filter structure 16 is arranged at the opening 17, and / or a fluid drive structure 2 is arranged at the opening 17.

[0070] like Figure 2 As shown, exemplarily, a third filter structure 163 and a fluid drive structure 2 are arranged at the position corresponding to the fifth plate 15. Figure 4 and Figure 10 As shown, in the second embodiment, the third filter structure 163 can be the first mesh cover 31 at the inlet end of the fluid drive structure 2. Of course, the outlet end 102 of the fluid drive structure 2 can also be configured with a second mesh cover 32.

[0071] Of course, it should be understood that the plates at other locations can also be missing to form other openings 17. For example, an opening 17 can be formed at the first plate 11, and the first filter structure 161 can be arranged using this opening 17.

[0072] In this case, the difficulty of forming the box body 1 and the complexity of its structure can be reduced to a certain extent.

[0073] Optionally, the inlet end 101 and the outlet end 102 are located at different positions on the box body 1.

[0074] like Figure 2 As shown, exemplarily, the outlet end 102 is located at the fifth plate 15, and the inlet end 101 is located at a plate outside the fifth plate 15. Thus, given the fixed size of the box body 1, both the inlet end 101 and the outlet end 102 can be arranged to cover a larger area, which can further ensure the flow rate requirements of the fluid.

[0075] Optionally, at least two inlet ends 101 are located at different orientations of the box body 1.

[0076] like Figure 2 As shown, exemplarily, at least two inlet ends 101 include a first inlet end 101a and a second inlet end 101b, which are located on the plate outside the fifth plate 15, so that with the size of the box body 1 being fixed, the first inlet end 101a and the second inlet end 101b can be arranged to cover a larger area, which can further ensure the flow rate requirement of the fluid.

[0077] Optionally, one of the at least two inlet ends 101 is disposed opposite to the corresponding outlet end 102, and the other of the at least two inlet ends 101 is disposed adjacent to the corresponding outlet end 102.

[0078] like Figure 2 As shown, exemplarily, a first inlet end 101a is formed at a first plate 11, a second inlet end 101b is formed at a second plate 12, and an outlet end 102 is formed at a fifth plate 15. The first plate 11 and the fifth plate 15 are arranged adjacent to each other, and the second plate 12 and the fifth plate 15 are arranged opposite to each other.

[0079] Thus, with one of the inlet ends 101 and the outlet end 102 positioned opposite each other, it is beneficial to ensure the smoothness of one of the fluid flow paths and to ensure the fluid flow rate requirement.

[0080] In a further alternative embodiment, at least two inlet ends 101 are provided with filter structures 16, and the set area corresponding to the filter structure 16 at the inlet end 101 opposite to the outlet end 102 is greater than or equal to the set area corresponding to the filter structure 16 at the inlet end 101 adjacent to the outlet end 102; wherein, the set area corresponding to any filter structure 16 is the total cross-sectional area of ​​the fluid channel of the filter structure 16.

[0081] It should be understood that any filter structure 16 has multiple fluid channels. Taking the first filter structure 161 as a mesh plate structure as an example, the mesh plate structure has multiple mesh holes, and multiple fluid channels are formed through the multiple mesh holes. The sum of the cross-sectional areas of the multiple mesh holes is the set area corresponding to the first filter structure 161.

[0082] Specifically, the set area corresponding to the second filter structure 162 is greater than or equal to the set area corresponding to the first filter structure 161. Therefore, when the outlet end 102 is driven by the fluid drive structure 2 to generate suction, the fluid flow from the second filter structure 162 to the outlet end 102 accounts for a relatively large proportion of the total fluid flow, which is beneficial to ensure the fluid flow of the filter box structure.

[0083] In this case, if multiple filter structures 16 are arranged in only one filtration path, it is preferable to arrange multiple filter structures 16 in the filtration path from the second filter structure 162 to the outlet end 102, with the first inlet end 101a as the main inlet and the second inlet end 101b as the auxiliary inlet, which can take into account both strong filtration requirements and fluid throughput requirements.

[0084] In the above embodiments, optionally, at least two filter structures 16 are stacked sequentially among the plurality of filter structures 16, and the adjacent ports of the fluid channels of the two stacked filter structures 16 are staggered.

[0085] like Figures 4 to 5 In the second embodiment shown, the plurality of filter structures 16 include a second filter structure 162 and a fourth filter structure 164. The second filter structure 162 is formed on the second plate 12 and integrally connected to the plurality of plates. The fourth filter structure 164 is located outside the second filter structure 162 and is detachably connected to the second filter structure 162 by fasteners. Both the fourth filter structure 164 and the second filter structure 162 are mesh structures. The cross-sectional area and cross-sectional shape of the mesh of the fourth filter structure 164 and the second filter structure 162 can be the same. The projection of the mesh of the fourth filter structure 164 onto the setting surface overlaps with the projection of the hole wall of the mesh of the second filter structure 162 onto the setting surface, thereby misaligning the mesh of the fourth filter structure 164 and the mesh of the second filter structure 162. The setting surface is the adjacent end face of the fourth filter structure 164 and the second filter structure 162.

[0086] In this way, the adjacent ports of the fluid channels of the two stacked filter structures 16 are staggered. The inlet wall of the flow channel of the downstream filter structure 16 can be used to block foreign objects from the upstream filter structure 16, thereby enhancing its filtration performance. Furthermore, it avoids setting the mesh size of the downstream filter structure 16 too small. In addition, in some scenarios, it also facilitates cleaning of the two filter structures 16 from both sides.

[0087] In the above embodiments, optionally, at least two of the plurality of filter structures 16 are stacked, and the stacked filter structures 16 are integrally connected or detachably connected.

[0088] like Figure 12 and Figure 13 As shown, Figure 12 This is a cross-sectional view of the filter housing structure and the fluid drive structure 2 after they are connected in the third embodiment of this disclosure; Figure 13 This is a partial structural diagram of the filter box structure in the third embodiment of this disclosure. In the third embodiment, the fourth filter structure 164 and the second filter structure 162 are both formed on the second plate 12 and integrally connected with other plates. For example, the second filter structure 162 and the fourth filter structure 164 are both mesh plates. The mesh holes of the second filter structure 162 and the fourth filter structure 164 can be processed on both sides of the second plate 12 respectively. Of course, in some cases, they can also be formed by integral molding technology, such as injection molding, which will not be described in detail here.

[0089] In the above embodiments, it should be understood that the multiple plates forming the box body 1 can be connected integrally or detachably, which is not a limitation.

[0090] Secondly, embodiments of this disclosure provide a filtration device, including a fluid drive structure 2 and a filter housing structure as described in the first aspect above, wherein the fluid drive structure 2 drives fluid to flow through the filter housing structure.

[0091] like Figure 3-11 As shown, optionally, the fluid drive structure 2 is disposed at the outlet end 102 of the body 1 of the filter box structure, and the mounting bracket 22 of the fluid drive structure 2 is detachably connected to the body 1.

[0092] For example, the fluid drive structure 2 includes a mounting frame 22 and a fan wheel 21. The mounting frame 22 is detachably connected to the box body 1, and the fan wheel 21 is mounted on the mounting frame 22.

[0093] It should be understood that the method of detachable connection between the mounting bracket 22 and the box body 1 is not limited. For example, the two can have a snap-fit ​​connection or a fastening connection, which will be illustrated later. When the fluid drive structure 2 is disassembled, it facilitates cleaning and maintenance of the inside of the box body 1.

[0094] like Figure 5-9 As shown, optionally, the box body 1 and the mounting bracket 22 are respectively provided with a guide structure 71 and a guide mating structure 72. The guide structure 71 is inserted into the guide mating structure 72. The guide structure 71 and the guide mating structure 72 can move relative to each other in a set direction. The set direction is set at an angle to the opening direction of the opening 17 of the box body 1.

[0095] A locking unit 8 is provided between the box body 1 and the mounting bracket 22. The locking unit 8 applies force to the box body 1 and the mounting bracket 22 in a set direction so as to lock the relative position of the box body 1 and the mounting bracket 22 in the set direction.

[0096] When the box body 1 and the mounting bracket 22 are locked in relative positions in a set direction, the box body 1 and the mounting bracket 22 are limited in the opening direction of the opening 17.

[0097] Specifically, the guide structure 71 and the guide mating structure 72 form a guide connection unit between the box body 1 and the mounting bracket 22. In this specification, the following description will use the example of the box body 1 having the guide structure 71 and the mounting bracket 22 having the guide mating structure 72. However, it should be understood that the arrangement can also be such that the box body 1 has the guide mating structure 72 and the mounting bracket 22 has the guide structure 71. When the guide structure 71 is inserted into the guide mating structure 72, the guide mating structure 72 can initially position the guide structure 71. The guide structure 71 and the guide mating structure 72 can move relative to each other in a set direction, and the guide mating structure 72 can guide the relative movement of the guide structure 71 in a set direction to a certain extent. The configuration of the guide connection unit is not limited and will be described exemplarily later.

[0098] In this disclosure, the example given is that the set direction and the opening direction of the opening 17 are perpendicular.

[0099] The structure of the locking unit 8 is not a limitation. When the guide structure 71 is inserted into the guide mating structure 72, the locking unit 8 can be used to manually or passively apply force between the box body 1 and the mounting bracket 22, so that the guide structure 71 and the guide mating structure 72 can move relative to each other in a set direction until the relative movement of the box body 1 and the mounting bracket 22 in the set direction is restricted. At this time, the locking unit 8 can lock the relative position of the box body 1 and the mounting bracket 22 in the set direction.

[0100] When the box body 1 and the mounting bracket 22 are locked in relative positions in a set direction, the way in which the box body 1 and the mounting bracket 22 are limited in the opening direction of the opening 17 is not a limitation. For example, the box body 1 and the mounting bracket 22 are limited in the opening direction of the opening 17 at the guide structure 71, and / or the box body 1 and the mounting bracket 22 are limited in the locking unit 8. The following will be explained in detail with reference to the embodiments.

[0101] Thus, the box body 1 and the mounting bracket 22 are respectively provided with a guide structure 71 and a guide engagement structure 72. When the guide structure 71 is inserted into the guide engagement structure 72, the guide structure 71 and the guide engagement structure 72 can move relative to each other in a set direction, that is, the box body 1 and the mounting bracket 22 can move relative to each other in a set direction. When the locking unit 8 applies force between the box body 1 and the mounting bracket 22 in the set direction, it can make the box body 1 and the mounting bracket 22 move relative to each other in the set direction until the relative movement of the box body 1 and the mounting bracket 22 in the set direction is restricted. At this time, the relative position of the box body 1 and the mounting bracket 22 in the set direction can be locked. When the mounting bracket 22 is locked in a relative position in a set direction, the box body 1 and the mounting bracket 22 are limited in the opening direction of the opening 17, which can realize the relative position locking of the box body 1 and the mounting bracket 22 in the opening direction of the opening 17, thereby realizing the assembly of the box body 1 and the mounting bracket 22. Conversely, when the locking force of the locking unit 8 is released, the guide structure 71 and the guide mating structure 72 are separated relative to each other by the relative movement of the box body 1 and the mounting bracket 22, thereby realizing the disassembly of the box body 1 and the mounting bracket 22. This solution can realize the connection and limitation of the box body 1 and the mounting bracket 22 in multiple directions, and can improve the efficiency of the disassembly and assembly operations, which is highly practical.

[0102] like Figure 2 , 7 As shown, optionally, the guide structure 71 includes an insertion structure 711, and the guide mating structure 72 includes a socket structure 721. The insertion structure 711 is inserted into the socket structure 721 along the opening direction of the open port 17. The dimension of the socket structure 721 in the set direction is larger than the dimension of the insertion structure 711 in the set direction.

[0103] Specifically, when the insertion structure 711 is inserted into the insertion hole structure 721, the two are slidably connected in the set direction. Thus, when the locking unit 8 applies force to the box body 1 and the mounting bracket 22 in the set direction, the box body 1 and the mounting bracket 22 slide in the set direction, and the relative position of the two in the direction perpendicular to the set direction and perpendicular to the opening direction is highly stable.

[0104] like Figure 7 As shown, in this case, optionally, a first abutting portion 73 is formed on the end of the insertion structure 711 near the insertion hole structure 721, and a first abutting mating portion 74 is formed on the end face of the insertion hole structure 721 away from the insertion structure 711; when the box body 1 and the mounting bracket 22 are locked in relative positions in a set direction, the first abutting portion 73 and the first abutting mating portion 74 are limited and connected in the opening direction of the opening 17.

[0105] It should be understood that the insertion hole structure 721 is also used for the passage of the first abutment portion 73. When connecting the box body 1 and the mounting bracket 22, the end of the insertion structure 711 containing the first abutment portion 73 is first inserted into the insertion hole structure 721 until the first abutment portion 73 has completely passed through the insertion hole structure 721. At this time, the insertion structure 711 and the insertion hole structure 721 are in a state where they can move relative to each other in the set direction. Then, when the locking unit 8 applies force between the box body 1 and the mounting bracket 22 in the set direction, the box body 1 and the mounting bracket 22 can move relative to each other in the set direction until the box body 1 and the mounting bracket 22 abut against each other in the set direction. For example, when the inner wall surface of the insertion hole structure 721 in the set direction abuts against the side wall of the columnar portion of the insertion structure 711 in the set direction, the relative position of the box body 1 and the mounting bracket 22 in the set direction can be locked, and the first abutment portion 73 and the first abutment mating portion 74 are in a state of abutting against each other in the opening direction of the opening 17.

[0106] Thus, the provision of the first abutting part 73 and the first abutting mating part 74 can enhance the connection strength between the box body 1 and the mounting bracket 22 in the opening direction of the insertion hole structure 721 in the opening direction of the open port 17. The structure is simple and highly practical.

[0107] like Figure 5 and Figure 6 As shown, the mounting bracket 22 has a first setting plate 221 at one end in the set direction. The first setting plate 221 is located inside or outside the box body 1. The side plate of the box body 1 opposite to the first setting plate 221 is the second setting plate 18. The locking unit 8 acts between the first setting plate 221 and the second setting plate 18.

[0108] In the second embodiment, the first setting plate 221 is shown to be located outside the box body 1. In this case, the second setting plate 18 is one of the two fourth plates 14 that is opposite to the first setting plate 221.

[0109] This configuration allows for a reasonable placement of the locking unit 8, facilitating its structural design.

[0110] like Figure 8-9 As shown, optionally, the locking unit 8 includes a first connector 81, and one of the first setting plate 221 and the second setting plate 18 located on the outer side is provided with a first connecting hole 82; wherein, the first connector 81 passes through the first connecting hole 82 and is detachably fixedly connected to the first connecting hole 82, and one of the first setting plate 221 and the second setting plate 18 located on the inner side abuts against the end of the first connector 81 that passes through the first connecting hole 82.

[0111] The first setting plate 221 is located outside the second setting plate 18. The first setting plate 221 is provided with a first connecting hole 82. The first connecting member 81 can be a threaded connector. The threaded connector is threadedly connected to the first connecting hole 82 and abuts against the second setting plate 18. The first connecting member 81 can apply force to make the box body 1 move in the forward direction of the corresponding arrow in the set direction until the box body 1 and the mounting bracket 22 abut against each other in the set direction. In this case, when the threaded connector is loosened to separate the threaded connector from the second setting plate 18, and the box body 1 and the mounting bracket 22 are in a detachable state, the threaded connector remains in the first connecting hole 82 because it is threadedly connected to the first connecting hole 82, preventing the threaded connector from falling out, thereby further improving the ease of disassembly and assembly of the box body 1.

[0112] The first connector 81 can also be a snap-fit ​​connector, which snaps into the first connecting hole 82 and abuts against the second setting plate 18. This scheme is not shown in the figure.

[0113] In a further alternative, a groove 83 is formed in an inner recess of the first setting plate 221 and the second setting plate 18. One end of the first connector 81, which passes through the first connecting hole 82, is accommodated in the groove 83 and abuts against the bottom of the groove 83.

[0114] Thus, the groove 83 can be used to position and guide the first connector 81.

[0115] In some scenarios, when one end of the first connector 81, which passes through the first connecting hole 82, is accommodated in the groove 83, the groove 83 and the first connector 81 are connected in a limiting manner in the opening direction of the open port 17. Thus, a limiting connection between the box body 1 and the mounting bracket 22 can be achieved at the first connector 81.

[0116] In other scenarios, the locking unit 8 includes a first connector 81, a first connecting hole 82 on the outer side of the first setting plate 221 and the second setting plate 18, and a second connecting hole on the inner side of the first setting plate 221 and the second setting plate 18. The first connector 81 passes through the first connecting hole 82 and the second connecting hole in sequence and is connected to the first connecting hole 82 and the second connecting hole respectively.

[0117] Specifically, the first connector 81 can be configured as a threaded connector, which passes through the first connecting hole 82 and the second connecting hole and is threadedly connected to the second connecting hole. In this case, the first connector 81 can reliably connect the first setting plate 221 and the second setting plate 18, resulting in a simple structure and strong practicality. This scheme is not shown in the figure. In this case, preferably, the first setting plate 221 is located in the positive direction of the box body 1 in the setting direction, which will not be described in detail here.

[0118] like Figure 5 , 6 As shown, optionally, the locking unit 8 further includes an elastic structure 85, which acts in a set direction between the second set plate 18 and the first set plate 221.

[0119] The elastic structure 85 acts along a set direction on the second set plate 18 and the first set plate 221, applying a pushing force between them.

[0120] Furthermore, one of the second setting plate 18 and the first setting plate 221 is provided with an elastic structure 85, and the other of the second setting plate 18 and the first setting plate 221 is provided with a limiting hole 86. The elastic structure 85 is partially accommodated in the limiting hole 86 and is limitedly connected to the limiting hole 86 in the opening direction of the opening 17.

[0121] like Figure 6 As shown, by way of example, the second setting plate 18 protrudes and forms an elastic structure 85. When the elastic structure 85 contacts the first setting plate 221, it provides a force in the setting direction. The arc-shaped protrusion and the limiting hole 86 are limited and connected in the opening direction of the opening 17.

[0122] Thus, the elastic structure 85 can be used to provide force in a set direction, and the elastic structure 85 can also be connected to the limiting hole 86 in the opening direction of the open port 17 to limit the force of both in the opening direction.

[0123] This disclosure provides a heat dissipation system that includes the filter housing structure described above, or the filter device described above.

[0124] This disclosure provides an electrical device that includes the above-described heat dissipation system.

[0125] like Figure 14 As shown, exemplarily, the electrical equipment is an inverter, and the heat dissipation system is the ventilation and heat dissipation system of the inverter. The inverter has a main body 6, and an air duct and a heat sink 5 are arranged on one side of the main body 6. The filter box structure is arranged at the inlet of the air duct housing 4 of the ventilation and heat dissipation system, so that air flows and dissipates heat from the heat sink 5 and other parts.
