Preferably, the cross section of the deflector hole 142 be round, oval, rectangular, triangle, it is trapezoidal, fan-shaped in times
It anticipates one or more combinations.
It should be noted that can have the deflector hole 142 of multiple shape, multilayer acoustical panel on one layer of acoustical panel 141
141 deflector hole 142 may be set to be different shapes.
It is understood that different passes is different to the cutting effect of bubble, it is arranged on same acoustical panel 141 different
The deflector hole 142 of shape enables to the fluid state entered in mixed flow chamber 143 diversification, to improve stream in mixed flow chamber 143
The mixed flow effect of body, and the acoustical panel 141 that different shape makes different layers is set by the deflector hole of multilayer acoustical panel 141 142
It can work in coordination, various forms of cuttings are carried out to bubble, improve the effect that acoustical panel 141 eliminates air pocket.
Specifically, as an example, 142 section of deflector hole on first layer acoustical panel 141 can be provided in round, the
142 section of deflector hole on two layers of acoustical panel 141 is set as rectangular, 142 section of the deflector hole setting on third layer acoustical panel 141
For sector.
Preferably, shown in combined with Figure 1 and Figure 2, the axis phase of the deflector hole 142 on the acoustical panel 141 of adjacent two pieces
Mutually it is arranged in a staggered manner.
It is understood that the deflector hole 142 on adjacent two pieces of acoustical panels 141 is shifted to install, enable to flow into mixed
The gas-liquid mixture fluid of stream chamber 143 need to flow out again after mixed flow in mixed flow chamber 143, to improve the mixed flow effect of mixed flow chamber 143, keep away
Exempt to cause fluid to directly flow through two layers of acoustical panel 141, without being filled since 141 spacing of adjacent two pieces of acoustical panels is too small
The mixed flow divided, reduces the thinning effect to air pocket.
It is noted that the pore size of the deflector hole 142 can be between 0.15 millimeter to 2 millimeters, and it is greater than
The aperture of strainer in air conditioner refrigerating liquid system, so as to avoid the valve muffler 14 by can be by the mistake in pipeline
Filter the impurity obstruction of device.
