摘要（英）：

The invention provides a low-noise air channel. The low-noise air channel comprises an air channel box provided with an air outlet and at least two air inlet pipes arranged on the air channel box. Each air inlet pipe comprises a first straight pipe, a bent pipe and a second straight pipe, wherein the first straight pipe is fixed to the air channel box, the bent pipe is arranged in the air channel box, the inner wall of the bent pipe is smooth, the bent angle of the bent pipe is 75-105 degrees, the inlet end of the bent pipe is connected with the first straight pipe, the outlet end of the bent pipe is connected with the second straight pipe, the second straight pipe is arranged in the air channel box, and the center axis of the second straight pipe is parallel to the center axis of the air channel box. The low-noise air channel has the advantages of being low in noise, small in pressure loss, good in flow equalizing effect and the like.
