Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
Reference picture 1,2 and 3, embodiment 1 of the present utility model, a kind of computer noise reduction cabinet, including casing 1, thermovent
2nd, fan 3, mainboard 7, hard disk 8, power supply 9 and a tubular acoustic silencer 4；Multiple air vents 1.1 are carried on casing 1；Fan 3 is set
On mainboard 7, one end face fan 3 of tubular acoustic silencer 4, the other end is connected to thermovent 2.
Tubular acoustic silencer 4 is provided with porous sound absorbing material layer 5 with the connection end of thermovent 2.
The tubular acoustic silencer 4 is straight tube-like.
When blower fan 3 operates, caused noise passes through tubular acoustic silencer 4, the sidewall friction of sound wave and tubular acoustic silencer 4, sound
It can propagate and decay along tubular acoustic silencer 4, so as to reach noise elimination purpose.
Tubular acoustic silencer 4 is straight tube-like, and this shape and structure is simple, is easy to the installation of tubular acoustic silencer 4.
