[0048] This embodiment provides a fan cover, which can improve its mechanical strength, reduce the occurrence of vibration, improve the stability and reliability of the fan cover, and save costs.

[0049] Such as Figures 1-4As shown in the figure, the fan cover mainly includes a body 100, a first fixing member 200, and a second fixing member 300. Among them, the body 100 has a first side wall 110 and a second side wall 120 that are perpendicularly connected to each other. One end of the first fixing member 200 is connected to the first side wall 110 of the body 100, and a first mounting hole 210 is formed in the first fixing member 200. The first mounting hole 210 is configured to be assembled with the fixing bracket 10. One end of the second fixing member 300 is connected to the second side wall 120 of the body 100, and a second mounting hole 310 is formed in the second fixing member 300. The second mounting hole 310 is configured to be assembled with the fixing bracket 10.

[0050] Based on the above design, in this embodiment, the body 100 covers the periphery of the fan 30, so that the body 100 can guide the air flow generated by the fan 30, prevent hot air from flowing back, and improve the heat dissipation efficiency. The body 100 is assembled with the fixing bracket 10 through the settings of the first fixing member 200 and the second fixing member 300, which can improve the stability and reliability of the connection between the body 100 and the fixing bracket 10, and reduce the vibration of the body 100 and the generation of noise during use. At the same time, since the body 100 is stably connected to the fixing bracket 10 through the first fixing member 200 and the second fixing member 300, there is no need to form mounting holes in the body 100, thereby improving the mechanical strength of the fan cover, extending the service life, and achieving the purpose of cost savings.

[0051] In addition, through the settings of the first fixing member 200 and the second fixing member 300, the fixing of the body 100 in two mutually perpendicular directions (the extending direction of the first side wall 110 and the extending direction of the second side wall 120) can be realized, thereby improving the stability and reliability of the fan cover.

[0052] Optionally, the body 100 in this embodiment can be set to a square, circular or other irregular shape according to actual needs, which will not be elaborated here one by one.

[0053] Optionally, both the first mounting hole 210 and the second mounting hole 310 in this embodiment are strip-shaped holes. This facilitates the operator to flexibly adjust the position of the body 100 on the fixing bracket 10, so that the fan 30 can be located at the center of the body 100, and ensure that there is a certain gap between the fan 30 and the first side wall 110 and the second side wall 120.

[0054] Optionally, both the first mounting holes 210 and the second mounting holes 310 in this embodiment can be provided in multiple numbers, and the multiple first mounting holes 210 are equally spaced, and the multiple second mounting holes 310 are equally spaced. This can improve the stability and reliability of the connection between the fan cover and the fixing bracket 10 while minimizing the phenomenon of stress concentration on the first fixing member 200 and the second fixing member 300, making the first fixing member 200 and the second fixing member 300 evenly stressed.

[0055] As Figures 1-2 shown, in this embodiment, the main body 100 includes two first side walls 110 and two second side walls 120, and the two first side walls 110 are arranged opposite to each other, and the two second side walls 120 are arranged opposite to each other and enclose a receiving cavity 150 for receiving the fan 30. Among them, the two second side walls 120 are respectively defined as a top side wall 130 and a bottom side wall 140, and the top side wall 130 is located above the bottom side wall 140. The first fixing member 200 is provided in two numbers, and each first fixing member 200 is connected to one first side wall 110, and the two first fixing members 200 are symmetrically arranged about the axis of the main body 100. This can improve the stability and reliability of the first fixing member 200 to the main body 100 and reduce the phenomena of vibration and noise generation of the main body 100.

[0056] The second fixing member 300 is connected to the top side wall 130 to further enhance the stability of the main body 100 and improve the stability and reliability of the fan cover.

[0057] Furthermore, the second fixing member 300 in this embodiment can be provided in multiple numbers, and the multiple second fixing members 300 are equally spaced. This can improve the stress uniformity of the top side wall 130 and avoid the phenomenon of stress concentration.

[0058] Optionally, the second fixing member 300 can be provided in two, three, four, five, etc.

[0059] Preferably, the second fixing member 300 in this embodiment is connected to the inner wall of the top side wall 130 so that the second fixing member 300 is located inside the receiving cavity 150. This can save the installation space of the fan cover as much as possible, reduce the volume of the fixing bracket 10, and improve the integration of the thermal management unit.

[0060] As Figures 1-2As shown, in this embodiment, a wire groove 160 and a wire hole 170 are provided on the first side wall 110 and / or the second side wall 120. The wire groove 160 is configured to pass the wire harness, and the wire hole 170 is configured to fix the wire harness. Exemplarily, in this embodiment, the wire groove 160 and the wire hole 170 are provided on the first side wall 110. The shape of the wire groove 160 can be set to be U-shaped. The wire harness of the fan 30 is passed through the wire groove 160, and then the wire harness is fixed to the wire hole 170 on the first side wall 110 by using a buckle, so as to prevent the wire harness from swinging randomly and affecting the normal operation of the fan 30, thereby improving safety.

[0061] like Figures 1-2 As shown, in this embodiment, the top of the first side wall 110 and the top of the second side wall 120 are both provided with a reinforced folded edge 600, and the reinforced folded edge 600 is folded and extended in a direction away from the main body 100. The setting of the reinforced folded edge 600 can improve the mechanical strength of the fan cover, reduce the risk of deformation, and extend the service life.

[0062] like Figures 1-2 As shown, the fan guard in this embodiment further includes a third fixing member 400, which is connected to the bottom side wall 140. The third fixing member 400 is provided with a third mounting hole 410, and the third mounting hole 410 is configured to be assembled with the fixing bracket 10. The provision of the third fixing member 400 can further improve the stability of the fan guard and reduce the phenomenon of vibration and noise.

[0063] Optionally, the third mounting hole 410 in this embodiment can be set as a strip hole. This makes it easier for operators to flexibly adjust the position of the fan cover on the fixing bracket 10, so that the fan 30 can be located at the center of the body 100, and ensure that a certain gap is maintained between the fan 30 and the first side wall 110 and the second side wall 120.

[0064] Optionally, the third mounting hole 410 in this embodiment can be set to multiple, and the multiple third mounting holes 410 are arranged at equal intervals. This can improve the stability and reliability of the connection between the fan cover and the fixed bracket 10 while minimizing the stress concentration phenomenon of the third fixing component 400, so that the third fixing component 400 is evenly stressed.

[0065] Furthermore, the middle area of ​​the bottom side wall 140 in this embodiment is convex, and the bottom side wall 140 is symmetrically arranged about the axis of the body 100. Optionally, the middle area of ​​the bottom side wall 140 in this embodiment protrudes outwardly with a trapezoidal groove, which can form an escape position for the installation of the fan 30, facilitating the assembly of the fan cover. Of course, the operator can also set the trapezoidal groove to other shapes, such as an arc groove, a square groove, etc., which will not be described one by one here.

[0066] Furthermore, a drainage hole 180 is provided in the middle region of the bottom side wall 140 in this embodiment. In this way, when there is liquid on the blower housing, the provision of the drainage hole 180 facilitates the drainage of the liquid, preventing the liquid from affecting the heat dissipation of the blower 30.

[0067] As Figures 1-2 shown, in this embodiment, the blower housing further includes a reinforcing rib 500, and the reinforcing rib 500 is provided on the first side wall 110 and / or the second side wall 120. Preferably, the reinforcing rib 500 is provided on the bottom side wall 140 of both the first side wall 110 and the second side wall 120 in this embodiment, which can improve the mechanical strength of the blower housing, reduce the risk of deformation of the blower housing, and extend the service life.

[0068] As Figures 3-4 shown, this embodiment also provides a thermal management unit, which includes a fixing bracket 10, a connecting member 20, a blower 30, and the above-mentioned blower housing. The blower 30 is arranged on the fixing bracket 10, the blower housing is sleeved on the periphery of the blower 30, and the first fixing member 200 and the second fixing member 300 are connected to the fixing bracket 10 through the connecting member 20.

[0069] Optionally, a plurality of connecting members 20 can be provided, and the connecting members 20 can be set as components such as bolts and screws. The blower 30 is detachably installed on the fixing bracket 10 through the connecting member 20, and the blower housing is detachably installed on the fixing bracket 10 through the connecting member 20, which is convenient for the disassembly, replacement, and maintenance of the blower 30 and the blower housing in the later stage, saving costs.

[0070] The blower housing can guide the hot air generated by the blower 30, effectively control the wind direction, prevent the hot air from flowing back, and thus achieve a good heat dissipation effect, saving energy consumption and costs.

[0071] Since the thermal management unit has the above-mentioned blower housing, therefore, the thermal management unit has high stability and high mechanical strength, can reduce the occurrence of vibration and noise, and achieve the purpose of saving costs.
