[0034] In the system air duct, a centrifugal fan is usually installed to accelerate the gas or change the direction of the airflow. In general, an air guide ring is also set at the air inlet of the centrifugal fan. The bell-mouth structure of the air guide ring can improve the air intake uniformity of the air inlet of the centrifugal fan. However, the current centrifugal fan and air guide ring are split structures, that is, the centrifugal fan and the air guide ring are installed separately in the system air duct. Generally, the air guide ring is installed first, and then the centrifugal fan is installed. Because the system air duct is relatively narrow, the centrifugal fan and the air guide ring are not easy to align when they are installed independently in the system air duct, and the disassembly and assembly are complicated. The coaxiality and installation accuracy of the centrifugal fan and the air guide ring are not high.

[0035] In view of this, the embodiment of the utility model provides a fan assembly and an electronic device, in which a fan body and an air guide are integrated and assembled on a mounting frame to form an integral structure, and the fan body and the air guide can be installed as a whole in the system air duct, replacing the independent installation of the air guide and the fan body, and can effectively improve the assembly coaxiality and accuracy of the fan body and the air guide after the fan assembly is installed in the system air duct, and prevent the air guide from being eccentric or scratched during the operation of the fan assembly. At the same time, as a minimum replaceable unit of the system air duct, the fan body realizes modular installation and disassembly, which is simple and convenient, and can save a lot of labor costs and maintenance costs. Moreover, the fan assembly only needs to be disassembled and assembled along the extension direction of the air duct, and the one-way disassembly and assembly method further improves the convenience of disassembly and assembly.

[0036] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a fan assembly, the fan assembly comprising:

[0038] The mounting frame 200 includes a first mounting plate 210, a second mounting plate 220 and a support assembly 230. The first mounting plate 210 and the second mounting plate 220 are connected by the support assembly 230 to form a receiving space;

[0039] The fan body 100 is disposed on the first mounting plate 210 and is located in the accommodation space, and the fan body 100 has an air inlet; and

[0040] The air guide member 300 is arranged on the second mounting plate 220 and is in the accommodating space. The air guide member 300 is in contact with the fan body 100 and is arranged corresponding to the air inlet, wherein the second mounting plate 220 is provided with air holes for the air guide member 300 to take in air.

[0041] In the technical solution adopted in this embodiment, the fan body 100 and the air guide 300 are integrated and assembled on the installation frame 200 to form an integral structure, and the fan body 100 and the air guide 300 can be installed as a whole in the system air duct, replacing the independent installation of the air guide 300 and the fan body 100, which can effectively improve the assembly coaxiality and accuracy of the fan body 100 and the air guide 300 after the fan assembly is installed in the system air duct, and prevent the air guide 300 from eccentricity or scratching during the operation of the fan assembly. At the same time, the fan body 100, as a minimum replaceable unit of the system air duct, realizes modular installation and disassembly, which is simple and convenient, and can save a lot of labor costs and maintenance costs. Moreover, the fan assembly only needs to be disassembled and assembled along the extension direction of the air duct, and the one-way disassembly and assembly method further improves the convenience of disassembly and assembly. In addition, the installation frame 200 is a frame structure, which can provide accommodation space for the air guide 300 and the fan body 100, which is convenient for installation. Moreover, force and vibration can be transmitted between the first mounting plate 210 and the second mounting plate 220 through the support assembly 230, and the force and vibration are dispersed, thereby achieving uniform force on the mounting frame 200, improving the rigidity and strength of the mounting frame 200, and further providing strong support for the fan body 100 and the air guide member 300, preventing vibration excitation and frequency resonance generated by the fan body 100 under high-speed rotation, thereby improving the reliability and life of the fan body 100, and reducing the probability of failure.

[0042] Specifically, the fan assembly includes a fan body 100, a mounting frame 200, and an air guide 300. Among them, the fan body 100 is used to accelerate the gas or change the direction of the airflow. The fan body 100 can be a volute-less fan, which discharges air in a circumferential direction and can effectively increase the air output. In one embodiment, the fan body 100 is a centrifugal fan. Of course, in other embodiments, the fan body 100 can also be an axial flow fan or other fan that can accelerate the gas flow in this embodiment, which is not limited here. As an optional method, the fan body 100 is a volute-less centrifugal fan.

[0043] The air guide member 300 is arranged corresponding to the air inlet of the fan body 100 and is in contact with the fan body 100, which can improve the air intake uniformity of the air inlet of the fan body 100. Optionally, the air guide member 300 is an air guide ring.

[0044] The mounting frame 200 is used to mount the fan body 100 and the air guide 300. It is understandable that the fan body 100 and the air guide 300 are integrated on the mounting frame 200, and the fan body 100, the air guide 300 and the mounting frame 200 form an entire structure, namely, a fan assembly. During assembly, the fan assembly can be directly mounted in the system air duct, so that the fan body 100 and the air guide 300 can be mounted simultaneously, simplifying the operation process, facilitating assembly and disassembly, and effectively improving the coaxiality and installation accuracy of the fan assembly and the air guide 300 in the system air duct. Moreover, the assembly and disassembly of the fan assembly in the system air duct only needs to be along the same direction, namely, the extension direction of the air duct, further improving the convenience of assembly and disassembly.

[0045] The mounting frame 200 includes a first mounting plate 210, a second mounting plate 220 and a support assembly 230, and the first mounting plate 210, the second mounting plate 220 and the support assembly 230 together enclose a receiving space. The first mounting plate 210 is used to mount the fan body 100, and the second mounting plate 220 is used to mount the air guide 300. After the air guide 300 and the fan body 100 are installed, the first mounting plate 210 and the second mounting plate 220 are connected and fixed together by the support assembly 230. In one embodiment, at least one of the first mounting plate 210 and the second mounting plate 220 is detachably connected to the support assembly 230, that is, the first mounting plate 210 and the support assembly 230 may be detachably connected, or the second mounting plate 220 and the support assembly 230 may be detachably connected, or both the first mounting plate 210 and the second mounting plate 220 may be detachably connected to the support assembly 230. Optionally, the detachable connection method may be a bolt connection, or of course, a snap connection, which is not limited here.

[0046] In this embodiment, the mounting frame 200 is a frame structure, and the force can be transmitted and dispersed on the mounting frame 200, thereby improving the uniformity of the force on the mounting frame, improving the rigidity and strength of the mounting frame 200, and further providing strong support for the fan body 100 and the air guide member 300, preventing vibration excitation and frequency resonance generated by the fan body 100 under high-speed rotation, thereby improving the reliability and life of the fan body 100, and reducing the probability of failure.

[0047] In one embodiment, referring to Figure 4 An extension portion 250 is provided at the end of the support member, and the cross-sectional area of ​​the extension portion 250 is larger than the cross-sectional area of ​​the end of the support member, thereby increasing the contact area between the support member and the first mounting plate 210, the support member and the second mounting plate 220, and improving the reliability of the support member connecting the first mounting plate 210 and the second mounting plate 220.

[0048] Exemplarily, in one embodiment of the present utility model, referring to Figure 5The support assembly 230 includes a plurality of support members, and the plurality of support members are arranged at intervals along the circumference of the fan body 100. In this way, the first mounting plate 210 and the second mounting plate 220 can be connected at a plurality of different positions in the circumference of the fan body 100 by means of the plurality of support members, thereby improving the connection reliability of the first mounting plate 210 and the second mounting plate 220.

[0049] For example, in one embodiment of the utility model, the support member has a frontal surface facing the fan body 100, wherein the frontal surface is arranged parallel to the incoming surface in the incoming flow direction to reduce the wind resistance generated by the support member. In this way, the support member can reduce the obstruction of the airflow at the air outlet of the fan body 100, improve the smoothness and uniformity of the air outlet, and prevent local turbulence. In this embodiment, the incoming flow direction is the air outlet direction of the fan body 100 at the position where the support member is located.

[0050] In one embodiment, the support member may be any one of an L-shaped sheet metal bracket, a square tube column, a round tube, and an elliptical tube column, which is not limited here.

[0051] As an option, the support is an elliptical tube column. Figure 5 , the long axis of the elliptical tube column at different positions is oriented in different directions and is parallel to the air outlet direction at the corresponding position. In this way, the support in the form of an elliptical tube column has a small blocking area for the airflow at the air outlet, effectively reducing the wind flow resistance and preventing the generation of vortices. Specifically, for a fan without a volute, the air is discharged in a circumferential direction, and an air outlet is formed between two adjacent blades. Although the blades will rotate during the operation of the fan without a volute, the air outlet direction at the same position on the circumference of the fan body 100 is basically fixed. In order to reduce the obstruction of the support to the air outlet, the long axis of the elliptical tube column is axially parallel to the air outlet direction corresponding to the position, so that the blocking area of ​​the airflow at the air outlet is smaller, effectively reducing the wind flow resistance. In one embodiment, four elliptical tube columns are provided, and the four elliptical tube columns are arranged in a rectangular shape, wherein the long axes of the two diagonally arranged elliptical tube columns are arranged in parallel, and the long axes of the two adjacent elliptical tube columns are arranged vertically, so that the obstruction to the airflow at the air outlet of the fan body 100 can be further reduced.

[0052] Exemplarily, in one embodiment of the present utility model, referring to Figure 1 and Figure 3The fan assembly also includes a radial adjustment structure 400, which connects the second mounting plate 220 and the air guide 300, so that the radial position of the air guide 300 is adjustable so that the air guide 300 and the rotor of the fan body 100 are coaxially arranged. In order to improve the coaxiality of the air guide 300 and the fan body 100, a radial adjustment structure 400 is provided, and the air guide 300 is fixed on the second mounting plate 220 through the radial adjustment structure 400, so that the radial position of the air guide 300 on the second mounting plate 220 can be adjusted, thereby improving the coaxiality of the air guide 300 and the fan body 100. That is to say, when assembling, the fan body 100 is first fixed on the first mounting plate 210, and the air guide 300 is preliminarily fixed on the second mounting plate 220 through the radial adjustment structure 400, and then the first mounting plate 210 and the second mounting plate 220 are fixed together by the support assembly 230. At this time, one end of the air guide 300 is sleeved inside the air inlet of the fan body 100. Then, the radial position of the air guide 300 is adjusted by the radial adjustment structure 400, so that the air guide 300 and the fan body 100 are coaxial, and the uniformity of the gap between the outer wall of the air guide 300 and the inner wall of the air inlet of the fan body 100 is improved.

[0053] Illustratively, in one embodiment of the utility model, the radial adjustment structure 400 includes a first mounting hole provided on the air guide member 300, a second mounting hole provided on the second mounting plate 220, and a locking member, the locking member passes through the first mounting hole and the second mounting hole to lock the air guide member 300 and the second mounting plate 220, one of the first mounting hole and the second mounting hole is a positioning hole, the other of the first mounting hole and the second mounting hole is a tolerance adjustment hole, and the aperture of the positioning hole is smaller than the aperture of the tolerance adjustment hole.

[0054] Specifically, the radial adjustment structure 400 includes a first mounting hole, a second mounting hole, and a locking member. The first mounting hole is provided on the air guide 300, the second mounting hole is provided on the second mounting plate 220, and the locking member penetrates the first mounting plate 210 and the second mounting plate 220 and fixes the air guide 300 on the second mounting plate 220. One of the first mounting hole and the second mounting hole is a positioning hole, and the other of the first mounting hole and the second mounting hole is a tolerance adjustment hole, the aperture of the positioning hole is smaller than the aperture of the tolerance adjustment hole, so that the locking member can be positioned through the positioning hole, and the radial position of the air guide 300 can be adjusted through the tolerance adjustment hole. Optionally, the locking member is a locking bolt. It is understandable that, during assembly, the fan body 100 is first fixed on the first mounting plate 210, the air guide 300 is initially fixed on the second mounting plate 220 by means of locking bolts (i.e., the locking bolts are not completely tightened, and the air guide 300 can move radially), and then the first mounting plate 210 and the second mounting plate 220 are fixed together by means of the support assembly 230. At this time, one end of the air guide 300 is sleeved inside the air inlet of the fan body 100, a mold is placed between the outer wall of the air guide 300 and the inner wall of the air inlet of the fan body 100, and the mold is slid circumferentially. When the mold slides to a position where there is a smaller gap between the outer wall of the air guide 300 and the inner wall of the air inlet of the fan body 100, the circumferential sliding of the mold will drive the air guide 300 to move radially, so that the gap between the outer wall of the air guide 300 and the inner wall of the air inlet of the fan body 100 is uniform, thereby improving the coaxiality of the air guide 300 and the fan body 100. Finally, the locking bolts are tightened, and the air guide member 300 is fixed on the second mounting plate 220 and remains stationary.

[0055] For example, refer to Figure 1 In one embodiment of the utility model, the first mounting plate 210 and / or the second mounting plate 220 are provided with an assembly structure 500, and the assembly structure 500 is used to connect an external fixture. To facilitate the overall installation of the fan assembly, the assembly structure 500 is provided on at least one of the second mounting plate 220 and the second mounting plate 220, and the entire fan assembly can be fixed to the external fixture through the assembly structure 500. In one embodiment, the assembly structure 500 can be an assembly hole.

[0056] Illustratively, in one embodiment of the utility model, the assembly structure is arranged on the second mounting plate 220, and the surface area of ​​the second mounting plate 220 is greater than the surface area of ​​the first mounting plate 210. In this way, the contact area between the mounting frame 200 and the external fixture can be increased, and the stability and supporting strength of the mounting frame 200 can be improved, thereby preventing the fan body 100 from generating resonance when running at high speed.

[0057] Exemplarily, in one embodiment of the present utility model, referring to Figure 2 and Figure 3, the edges of the first mounting plate 210 and / or the second mounting plate 220 are provided with a reinforcing fold 240. It is understandable that the reinforcing fold 240 can be provided at the edge of the first mounting plate 210, the reinforcing fold 240 can be provided at the edge of the second mounting plate 220, and the reinforcing fold 240 can be provided at the edge of the first mounting plate 210 and the edge of the second mounting plate 220 at the same time, so that the structural strength of the mounting frame 200 can be improved, and the fan body 100 and the air guide 300 can be effectively supported.

[0058] For example, in one embodiment of the present invention, the fan body 100 and the first mounting plate 210 are detachably connected. In this way, the corresponding fan body 100 can be replaced according to different needs, thereby increasing the use range of the fan assembly and facilitating the disassembly and maintenance of the fan body 100.

[0059] In another embodiment, the air guide member 300 is detachably connected to the second mounting plate 220, so that the air guide member 300 can be easily replaced and repaired, thereby reducing maintenance costs.

[0060] To achieve the above purpose, the embodiment of the utility model provides an electronic device, the electronic device includes a device body and a fan assembly connected to the device body, the fan assembly is the fan assembly described above, the second mounting plate is provided with an assembly structure, and the fan assembly is connected to the device body through the assembly structure. Specifically, the specific structure of the fan assembly refers to the above embodiment, and since the electronic device adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here one by one.

[0061] In one embodiment, the device body can be a converter, an inverter or an auxiliary power supply, etc., which will generate heat during operation and need to be cooled by forced air cooling. The fan assembly in this embodiment can play the functions of cold air being sucked in, internal convection air heat exchange and hot air discharge, effectively reducing the surface temperature of the device body. The electronic equipment or fan assembly in this embodiment is particularly suitable for the subway field. The subway will vibrate during operation, and the fan body will also vibrate when working. In order to prevent the fan body and the subway from resonating, it is necessary to reliably fix the fan body. The mounting frame in this embodiment is a frame structure, and the force can be transmitted and dispersed on the mounting frame, which improves the uniformity of the force of the mounting frame, has sufficient rigidity, strength and good self-mode, and then provides strong support for the fan body and the air guide, prevents the vibration excitation and frequency resonance generated by the fan body under high-speed rotation, improves the reliability and life of the fan body, and reduces the probability of failure. Of course, the electronic equipment or fan assembly in this embodiment can also be applied to other fields, which are not limited here.
