[0021] Due to the angle of the drawing, some parts may not be drawn, but their positions and connections can be understood from the text descriptions.

[0022] like Figure 1 As shown, this utility model is a noise reduction structure for a motor using IC611 cooling. The motor, employing IC611 cooling, consists of a motor 16 and a cooler 17. A noise reduction shroud is installed on the sides of the motor 16 and the cooler 17. An external fan 18 is located at the end of the motor 16, within the noise reduction shroud. A sound-absorbing layer is laid inside the noise reduction shroud.

[0023] The silencer shroud has an inlet silencer chamber 20 and an outlet silencer chamber 19 connected on both sides. The external fan 18 is located in the outlet silencer chamber 19, which is connected to the cooler 17.

[0024] like Figure 2 As shown, the soundproof hood includes an upper ventilation box 3 and a lower ventilation box 6 connected together, a partition plate 2, an air inlet guide plate 7, and an air outlet guide plate 10. The upper ventilation box 3 has an air inlet mesh plate 1 and an air outlet 4 on its upper two sides respectively. The partition plate 2 is vertically installed in the middle of the upper ventilation box 3. The air inlet guide plate 7 is provided between the air inlet mesh plate 1 and the partition plate 2. The air outlet 4 is provided between the partition plate 2 and the partition plate 2. The lower ends of the air inlet guide plate 7 and the air outlet guide plate 10 are connected to the upper middle part of the partition plate 2, and the upper ends of the air inlet guide plate 7 and the air outlet guide plate 10 are connected to the top two sides of the upper ventilation box 3.

[0025] The sound-absorbing layer consists of sound-absorbing felt 12 and sponge 5. The sound-absorbing felt 12 is installed with adhesive 11 on the side of the air inlet guide plate 7 facing the air inlet mesh plate 1, the side of the exhaust guide plate 10 facing the exhaust port 4, the upper sides of the lower ventilation box 6, and the bottom. The sponge 5 is placed between the overlapping parts of the upper ventilation box 3 and the lower ventilation box 6.

[0026] like Figure 3As shown, the installation structure of the sound-absorbing felt 12 is as follows: a wire mesh 13 is laid on the outside of the sound-absorbing felt 12 for protection. The connecting rod 15 passes through the wire mesh 13 and the sound-absorbing felt 12 and then connects to the sound-absorbing hood to complete the fixation of the sound-absorbing felt 12. The connecting rod 15 is L-shaped, and a gasket 14 is placed between the connecting rod 15 and the wire mesh 13 to increase the fixation stability of the sound-absorbing felt 12.

[0027] The connecting rod 15 is connected to the gasket 14 and the sound-absorbing hood by spot welding.

[0028] A ventilation plate 8 is installed between the bottom of the partition plate 2 and the lower ventilation box 6. The ventilation plate 8 has a ventilation opening located on the side of the external fan 18. The ventilation plate 8 and the partition plate 2 divide the silencer hood into an air inlet silencer chamber 20 and an air outlet silencer chamber 19.

[0029] To facilitate the installation of motor 16, a baffle 9 is installed on the side of the lower ventilation box 6.

[0030] The working process of this utility model is as follows:

[0031] When the motor 16 is running, driven by the external fan 18, air enters the air intake silencer 20 from the air intake mesh plate 1, passes through the ventilation plate 8 and enters the air outlet silencer 19, and finally enters the cooler 17 from the exhaust port 4, taking away the temperature inside the cooler 17.

[0032] During airflow, air vibrates and rubs against the inner wall of the silencing shroud. The sound-absorbing layer installed in the shroud can reduce the amplitude of this vibration, thus reducing noise. Experimental results show that this new type of motor silencing shroud can reduce noise by about 8dB. At the same time, there is a ring-shaped chamfer at the right angle of each cavity of the upper ventilation box. This structure can effectively reduce air turbulence inside the shroud, reduce noise, make the airflow smoother, and improve cooling efficiency.

[0033] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
