It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] See Figure 1-5 This invention provides a fan mounting structure 100 for an inverter. The fan mounting structure 100 includes a housing, a duct cover 10 fixed inside the housing, and a fan mounting bracket 20 slidably connected to the duct cover 10 for mounting multiple cooling fans. The duct cover 10 includes a guide surface 11 and a ventilation surface 12 arranged perpendicularly to each other. A first guide rail 13 for guiding and fixing the fans is provided on the guide surface 11. A positioning surface is also provided between the guide surface 11 and the ventilation surface 12. A positioning pin 14 for positioning the fan mounting bracket 20 is provided on the positioning surface. A push-pull part 22 is provided at one end of the fan mounting bracket 20. By pushing and pulling the push-pull part 22 of the fan mounting bracket 20, the fan mounting bracket 20 is slidably connected to the duct cover 10. The inverter fan mounting structure 100 provided by this utility model allows the fan mounting bracket 20 to be slidably connected to the air duct cover 10 by pulling the push-pull part 22 of the fan mounting bracket 20 outward. This enables the cooling fan to be removed from the housing and maintained, effectively avoiding the need to first remove the inverter and then remove the cooling fan from the housing, thus significantly improving the convenience and efficiency of fan maintenance. Furthermore, the guide rail 13 provided on the guide surface 11 allows for... The displacement accuracy of the fan mounting bracket 20 slidingly connected to the air duct cover 10 is effectively improved, thereby avoiding the wear caused by the fan mounting bracket 20 shaking inside the air duct cover 10. By setting the positioning pin 14 on the positioning surface, the positioning accuracy between the fan mounting bracket 20 and the air duct cover 10 can be effectively improved when the push-pull part 22 of the fan mounting bracket 20 is pushed inward so that the fan mounting bracket 20 is fully installed in the air duct cover 10, thereby ensuring the heat dissipation effect of the cooling fan, and thus ensuring the heat dissipation effect of the fan mounting structure 100 of the inverter.

[0024] like Figure 2 and Figure 3As shown, in the embodiment provided by this utility model, the other end of the fan mounting bracket 20 has a positioning hole 21 for the positioning pin 14 to be inserted and positioned. By inserting the positioning pin 14 on the positioning surface of the air duct cover 10 into the positioning hole 21 of the fan mounting bracket 20, the positioning accuracy between the fan mounting bracket 20 and the air duct cover 10 can be effectively improved after the push-pull part 22 of the fan mounting bracket 20 is pushed inward, so that the fan mounting bracket 20 is fully installed on the air duct cover 10, thereby ensuring the heat dissipation effect of the cooling fan, and thus ensuring the heat dissipation effect of the fan mounting structure 100 of the inverter. In the embodiment provided by this utility model, the fan mounting bracket 20 is provided with a plurality of mounting holes 23 for mounting the cooling fan, and each mounting hole 23 is provided with a plurality of first fixing holes 24 for locking members to pass through and lock. By installing multiple cooling fans in the mounting holes 23, the positioning accuracy of the multiple cooling fans on the fan mounting bracket 20 can be effectively improved. By using bolts, studs and pins and other locking components to pass through the cooling fans and lock them in the first fixing holes 24 of the fan mounting bracket 20, the stability of the cooling fans installed on the fan mounting bracket 20 can be effectively improved.

[0025] In addition, such as Figure 1 and Figure 4 As shown in the embodiment provided by this utility model, each mounting hole 23 is also provided with a mounting groove 25 for the cooling fan cable to pass through and exit. By passing the cooling fan cable through the mounting groove 25, the neatness of the cooling fan cable on the fan mounting bracket 20 can be effectively improved, thereby further improving the rationality of the cooling fan layout within the housing, and further improving the convenience and safety of operators in maintaining the cooling fan.

[0026] like Figure 1 and Figure 3 As shown in the embodiment provided by this utility model, a plurality of air duct baffles 15 are also provided on the first guide rail 13 on the guide surface 11, which divide the interior of the air duct cover 10 into a plurality of air ducts. By dividing the interior of the air duct cover 10 into a plurality of air ducts using the air duct baffles 15, the air blown by the cooling fan can be effectively guided and communicated with the outside through the ventilation surface 12 of the air duct cover 10, blowing out of the housing, thereby effectively ensuring the heat dissipation effect of the cooling fan while avoiding mutual interference between the air blown by the cooling fan. The end of the guide surface 11 provided by this utility model is also provided with a vertical mounting surface 16, and the air duct cover 10 is fixed to the housing through the mounting surface 16. A plurality of second fixing holes 161 are provided on the mounting surface 16 for locking members to pass through and lock. By using bolts, studs, and pins to pass through the second fixing hole 161 on the mounting surface 16 of the duct cover 10 and lock it into the housing, the stability of the duct cover 10 installed in the housing can be effectively guaranteed, thereby effectively guaranteeing the stability of the fan mounting bracket 20 slidingly connected to the duct cover 10.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the ventilation surface 12 of the air duct cover 10 provided by this utility model is provided with a plurality of heat dissipation holes 121 for connecting the cooling fan with the external environment. By utilizing the plurality of heat dissipation holes 121 provided on the ventilation surface 12 of the air duct cover 10 for connecting the cooling fan with the external environment, the heat dissipation effect of the plurality of cooling fans on the fan mounting bracket 20 can be effectively guaranteed. Furthermore, the second guide rail 13 provided in the housing for guiding the fan mounting bracket 20 can cooperate with the first guide rail 13 on the air duct cover 10, thereby further improving the guiding accuracy of the air duct cover 10 and the housing for the fan mounting bracket 20, and further improving the displacement accuracy of the fan mounting bracket 20 slidingly connected to the air duct cover 10.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
