DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0039] In the description of the present application, it should be understood that the terms "height", "thickness", "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, the meaning of "multiple" is two or more, at least one of which can be one, two or more, unless otherwise explicitly specified. In the description of the present application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, within an angle range of 85°-95°, it is considered as perpendicular, similarly, "parallel" means completely parallel or almost completely parallel, for example, within a range of 10° of complete parallel, it is considered as parallel.

[0040] It should also be noted that in the drawings of the embodiments of the present application, the arrow marked X represents the first direction X of the fan cover. The first direction X is introduced to more clearly represent the structure and relative positional relationship of the components in the fan cover. In actual application, the first direction X may change according to the different placement modes of the fan cover.

[0041] As a prologue of the embodiments of the present application, the electrical equipment such as power cabinet in the power industry adopts air cooling mode for heat dissipation, that is, an air inlet and an air outlet are arranged on the shell of the electrical equipment, external air is driven by a fan to enter the inside of the shell through the air inlet to blow the internal heating devices, and the heated air is discharged through the air outlet.

[0042] The air inlet of the shell is generally covered by an air inlet screen cover to play a role in protection and air filtration. However, such an air inlet screen cover is usually processed by sheet metal technology, and the overall volume will increase with the increase in the number of fans. Generally, the fan is arranged on the top side of the power cabinet. If the fan needs to be overhauled, the fan cover needs to be completely removed, and then the fan cover is installed after the overhaul, which is time-consuming and laborious and brings many inconveniences to daily maintenance work.

[0043] Please combine Figure 1 , Figure 2 and Figure 3 The fan cover of the embodiment of the present application is used to cover the fan 9 on the top side of the cabinet 8. The fan cover includes a first cover assembly 1, a cover plate assembly 2, and a lock assembly 3. The first cover assembly 1 includes a heat dissipation shell 11, which is arranged on the cabinet 8. The heat dissipation shell 11 is provided with a containing cavity 110 and a first opening 111 communicating with the containing cavity 110. The fan 9 is located in the containing cavity 110, so that the fan 9 is isolated from the outside through the heat dissipation shell 11, playing a protective role for the fan 9. At the same time, isolation does not mean that the fan 9 is enclosed in the containing cavity 110. It can still draw external air to flow into the containing cavity 110.

[0044] The cover plate assembly 2 includes a body part 21, which is arranged on the first opening 111 to seal the first opening 111, so that external impurities cannot enter the containing cavity 110 through the first opening 111.

[0045] The lock assembly 3 connects the body part 21 and the heat dissipation shell 11 to realize the detachable connection between the body part 21 and the heat dissipation shell 11. The lock assembly 3 includes a first clamping piece 31 and a second clamping piece 32. The first clamping piece 31 is connected to the body part 21, and the second clamping piece 32 is connected to the heat dissipation shell 11. The first clamping piece 31 and the second clamping piece 32 are connected in a clamping manner. The clamping connection means that the first clamping piece 31 and the second clamping piece 32 have a mutual cooperation relationship in geometry and / or size, which can realize repeated connection and disconnection of two components. For example, a protruding structure and a hole structure are inserted, the cooperation of the shapes of the two restricts the mutual movement away from each other in a certain direction; or the fixation is realized by the interaction force between them. The interaction force can be realized by the cooperation of the size tolerance, such as interference fit. The protruding structure and / or the hole structure can be set to be elastic or magnetic, and the elastic deformation force or magnetic force is used to realize the fixation between them. The protruding structure can also be set to be a spring pin, a spring lock block, etc., to indirectly exert force on the hole structure.

[0046] During the maintenance, the body part 21 can be detached from the heat dissipation shell 11 alone, and the fan 9 in the accommodating cavity 110 is operated through the first opening 111. Compared with the whole fan cover, the single body part 21 has small volume, light weight, and is convenient to assemble and disassemble, which helps to improve the convenience of the maintenance operation of the fan 9.

[0047] In some other embodiments, the fan 9 can also be arranged on the outer peripheral wall surface of the cabinet body 8 except the top side, and the fan cover is arranged corresponding to the fan 9 on the outer peripheral wall surface of the cabinet body 8.

[0048] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the second clamping part 32 is arranged in the accommodating cavity 110, and the second clamping part 32 includes a mounting part 321 and a clamping part 322. The mounting part 321 is connected to the inner wall of the accommodating cavity 110, and the clamping part 322 is connected to the mounting part 321 perpendicularly. The clamping part 322 is provided with a clamping groove 323 penetrating along the thickness direction thereof, and at least part of the first clamping part 31 passes through the clamping groove 323 and abuts against part of the clamping groove 323. The first clamping part 31 is configured to be movable along the length direction of the clamping groove 323, so as to clamp the clamping part 322 and drive the body part 21 to cover and seal the first opening 111. Specifically, the first clamping part 31 is L-shaped, and a clamping opening is formed between the first clamping part 31 and the body part 21, and the clamping opening is arranged towards the cabinet body 8. During the mounting, the body part 21 is moved, part of the first clamping part 31 passes through the clamping groove 323, and then the body part 21 is moved downward to drive the first clamping part 31 to move along the clamping groove 323 until the clamping part 322 is embedded in the clamping opening, so that the body part 21 is supported on the cabinet body 8. In this way, the relative displacement between the body part 21 and the heat dissipation shell 11 in the length direction perpendicular to the clamping groove 323 is limited, and the assembly and disassembly are convenient and fast. After the first clamping part 31 and the clamping groove 323 are inserted, the mutual moving away of the first clamping part 31 and the clamping groove 323 in the length direction of the heat dissipation shell 11 is limited by the shape cooperation of the first clamping part 31 and the clamping groove 323, so that the structure of the first clamping part 31 and the second clamping part 32 can be simplified. In addition, since the second clamping part 32 is arranged in the accommodating cavity 110, after the first clamping part 31 and the second clamping part 32 are clamped, they are also located in the accommodating cavity 110, which can reduce the structure of the body part 21 and the heat dissipation shell 11 protruding from the outer surface thereof, and maintain the flatness of the outer side of the fan cover.

[0049] Please refer to Figure 5In some embodiments, the card slot 323 comprises a first slot portion 3231 and a second slot portion 3232 arranged along the length direction of the card slot 323, the first slot portion 3231 and the second slot portion 3232 are in communication, the slot width of the first slot portion 3231 is greater than the slot width of the second slot portion 3232, and is greater than the thickness of the first clamping piece 31, and the body portion 21 covers the first opening 111 in the state that the first clamping piece 31 is clamped in the second slot portion 3232. The slot width of the first slot portion 3231 is relatively large, so that the first clamping piece 31 has a certain deviation allowance when being inserted, and the first clamping piece 31 and the clamping portion 322 are quickly inserted; the slot width of the second slot portion 3232 is reduced, so as to reduce the gap between the first clamping piece 31 and the inner wall surface of the second slot portion 3232, so as to limit the space of the relative displacement of the first clamping piece 31, thereby improving the relative position accuracy between the body portion 21 and the heat dissipation shell 11, and guaranteeing the coverage of the body portion 21 to the first opening 111.

[0050] Please refer to Figure 4 In some embodiments, the cover plate assembly 2 further comprises a flange portion 22, the flange portion 22 is connected to the body portion 21 and extends towards the heat dissipation shell 11, the flange portion 22 is attached to the outer wall surface of the heat dissipation shell 11, or at least part of the flange portion 22 is located in the accommodation cavity 110 and attached to the inner wall surface of the accommodation cavity 110. The fan cover further comprises a first connecting piece 4, the first connecting piece 4 connects the flange portion 22 and the heat dissipation shell 11.

[0051] The flange portion 22 provides a mounting basis for the first connecting piece 4 on the one hand, and increases the thickness of the body portion 21 and the heat dissipation shell 11 at the connection on the other hand, so that the strength of the connection is improved, and the flange portion 22 also partially covers the gap between the body portion 21 and the heat dissipation shell 11. The first connecting piece 4 can adopt a screw, and the flange portion 22 and the heat dissipation shell 11 are fixed by the screw, and in some other embodiments, the first connecting piece 4 can also adopt a pin, a bolt, an elastic cylindrical pin, etc.

[0052] Please refer to Figure 3 and Figure 4In some embodiments, the first opening 111 is arranged at one end of the heat dissipation shell 11 along a first direction X, the first direction X is the length direction of the air baffle, and is parallel to the length direction of the cabinet 8. The flange portion 22 is arranged on the side of the body portion 21 away from the cabinet 8. In the horizontal direction, the extension range of the top side gap between the body portion 21 and the heat dissipation shell 11 is larger than that of the side gap. The flange portion 22 covers the top side gap, which can greatly reduce the possibility of particles in the external air falling into the heat dissipation shell 11 from the top side gap under the action of gravity. In addition, when the cabinet 8 is placed, the first opening 111 faces the user side, that is, when the user faces the cabinet 8, the flange portion 22 and the first connecting piece 4 are located on the top side of the heat dissipation shell 11 and are in the user's visual blind area, which is beneficial to improve the visual effect of the air baffle on the user, so as to meet different design requirements.

[0053] For reference Figure 3 In some embodiments, the first cover assembly 1 further comprises a first flange 12 connected to the side of the heat dissipation shell 11 close to the cabinet 8 and abutting against the cabinet 8. The air baffle further comprises a second connecting piece 5 connecting the first flange 12 and the cabinet 8, realizing detachable connection of the heat dissipation shell 11 and the cabinet 8, so as to facilitate the entire heat dissipation shell 11 to be removed when a wide range of maintenance is required for the fan 9. The first flange 12 provides a basis for the installation of the second connecting piece 5, and is also beneficial to increase the structural strength of the heat dissipation shell 11 at this connection position, so as to avoid the second connecting piece 5 occupying the main structure of the heat dissipation shell 11. The second connecting piece 5 can be one of a screw, a pin, a bolt and an elastic cylindrical pin. In the example of the embodiment of the present application, the first flange 12 is connected to the cabinet 8 through a screw.

[0054] For reference Figure 3 In some embodiments, the first flange 12 is arranged in the receiving cavity 110, and correspondingly, the second connecting piece 5 is also located in the receiving cavity 110. The first flange 12 and the second connecting piece 5 are covered by the heat dissipation shell 11, which can block the contact of rainwater with the second connecting piece 5 and reduce the possibility of rusting of the second connecting piece 5. In addition, the first flange 12 and the second connecting piece 5 are located in the heat dissipation shell 11, which reduces the occupation of the heat dissipation shell 11 to the space outside it, thereby being beneficial to maintaining the flatness of the outer surface of the heat dissipation shell 11.

[0055] For reference Figure 3 and Figure 6 In some embodiments, the heat dissipation shell 11 is provided with a second opening 112, which communicates with the receiving cavity 110 and is used to cooperate with the traction of the fan 9, so that the external air can enter the cabinet 8 through the second opening 112.

[0056] The air baffle further comprises a second cover assembly 6, the second cover assembly 6 comprises an air inlet shell 61 arranged on the cabinet body 8, the air inlet shell 61 covers the second opening 112, the air inlet shell 61 is provided with an air cavity 611 and a plurality of air holes 612 communicating with the air cavity 611, the plurality of air holes 612 are respectively arranged on the top side of the air inlet shell 61 and the side opposite to the heat dissipation shell 11, and the air holes 612 communicate with the second opening 112 through the air cavity 611. The air inlet shell 61 and the cabinet body 8 are detachably connected. For example, the air inlet shell 61 and the cabinet body 8 can be respectively provided with a protruding structure and a groove structure, the protruding structure is inserted into the groove structure, and the two are tightly fitted, so that the protruding structure is limited in the groove structure, thereby realizing the fixation of the air inlet shell 61 and the cabinet body 8.

[0057] When the fan 9 works, the external air enters the air cavity 611 through the air holes 612, then enters the containing cavity 110 through the second opening 112, and then is introduced into the cabinet body 8 through the fan 9 for ventilation and heat dissipation; the air holes 612 play a filtering role on the air flow to prevent large impurities from being sucked into the air baffle. Since the air flow first enters the air inlet shell 61, part of the impurities carried in the air flow will accumulate in the air cavity 611, and the air inlet shell 61 and the cabinet body 8 are detachably connected, thereby realizing the purpose of separately disassembling the air inlet shell 61 for cleaning. The air baffle further increases the windward surface of the heat dissipation shell 11, so that air in multiple directions can enter the containing cavity 110 through the air holes 612, thereby ensuring sufficient air flow when the cabinet body 8 is cooled and fully utilizing the top space and side space of the cabinet body 8.

[0058] Please combine Figure 2 and Figure 3 In some embodiments, the second cover assembly 6 further comprises a filter screen 100, the filter screen 100 is arranged in the air cavity 611 and connected with the air inlet shell 61, and the plurality of air holes 612 are arranged on the side of the filter screen 100 away from the second opening 112. The filter screen 100 is arranged opposite to the second opening 112 and divides the air cavity 611 into two parts arranged along the first direction X, one part corresponds to the air holes 612, and the other part corresponds to the second opening 112; the air entering from each air hole 612 will first filter out large impurities through the air hole 612, and then further filter out small particles when passing through the filter screen 100, thereby improving the cleanliness of the air and reducing the influence on the internal components of the cabinet body 8.

[0059] Please combine Figure 6 , Figure 7 and Figure 8In some embodiments, the heat dissipation shell 11 is provided with a matching part 13 on one side facing the air inlet shell 61, and the air inlet shell 61 is provided with a positioning part 62 on one side facing the heat dissipation shell 11, the positioning part 62 is oppositely arranged with the matching part 13, and the two are inserted and fitted to limit the relative displacement of the air inlet shell 61 in the second direction, and the second direction intersects with the insertion direction of the positioning part 62. Through the insertion and fitting of the positioning part 62 and the matching part 13, on the one hand, the relative position between the air inlet shell 61 and the heat dissipation shell 11 during installation can be quickly determined, ensuring that the air inlet shell 61 covers the second opening 112, and on the other hand, the connection of the air inlet shell 61 can be stabilized.

[0060] In the embodiments of the present application, the matching part 13 is a hole structure, and the positioning part 62 is a protruding structure, the protruding structure is inserted into the hole structure, at the same time, the matching part 13 is located in the accommodating cavity 110, and the positioning part 62 is located in the air cavity 611; in some other embodiments, the matching part 13 can also be a protruding structure, and the positioning part 62 is a hole structure, the matching part 13 is located outside the heat dissipation shell 11, and the positioning part 62 is located outside the air inlet shell 61.

Since the displacement of the air inlet shell 61 in the second direction is limited, the displacement of the air inlet shell 61 in the insertion direction of the positioning part 62 is limited through the detachable connection structure, so that the stable connection of the air inlet shell 61 can be realized. The detachable connection structure can adopt one of a screw, a pin, a bolt and an elastic cylindrical pin. In the embodiments of the present application, the second folded edge 63 is fixed to the cabinet 8 through a screw.

[0062] In some other embodiments, the connection between the air inlet shell 61 and the heat dissipation shell 11 can also adopt the combination of the lock buckle assembly 3 and the first connecting piece 4, similarly, the body part 21 and the heat dissipation shell 11 can also be inserted and positioned through the matching part 13 and the positioning part 62, and then assembled in combination with the detachable connection structure, so as to realize the detachable connection between the body part 21, the heat dissipation shell 11 and the air inlet shell 61.
