Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, a silencing cylinder head for a refrigeration compressor includes a cylinder head body 1, an air outlet 2 disposed on the left side of the cylinder head body 1, and an air inlet 3 disposed on the right side of the cylinder head body 1, wherein a noise reduction structure for reducing noise is disposed on the left side of the air outlet 2.
As shown in fig. 1, the noise reduction structure comprises a first flange 4 fixedly connected to an air outlet 2, a second flange 5 fixedly connected to the left side of the first flange 4, a connecting pipe 6 fixedly connected to the left side of the second flange 5, a buffer chamber 7 fixedly connected to the left end of the connecting pipe 6, a buffer step 8 fixedly connected to the inner bottom wall of the buffer chamber 7, a transmission pipe 9 fixedly connected to the upper surface of the buffer chamber 7, a transfer chamber 10 fixedly connected to one end of the transmission pipe 9 far away from the buffer chamber 7, a guide plate 11 fixedly connected between the inner top wall and the inner bottom wall of the transfer chamber 10, three exhaust pipes 12 fixedly connected to the right side of the guide plate 11, and a silencing plate 13 fixedly connected between the inner top wall and the inner bottom wall of the exhaust pipes 12.
It should be noted that, cavity 14 has been seted up to the inboard of cylinder head body 1, and cavity 14 and gas outlet 2, air inlet 3 intercommunication, and the equal fixedly connected with amortization cotton 15 of interior roof and the interior diapire of cavity 14, first ring flange 4 and second ring flange 5 pass through the bolt interconnect, the inboard in the centre of a circle of first ring flange 4 and the inboard in the centre of a circle of second ring flange 5 all fixedly connected with rubber sound insulation strip 16, the upper surface of buffering step 8 upwards rises from left to right, transfer room 10 fixedly connected with is in the left side of cylinder head body 1 upper surface, three water conservancy diversion hole has been seted up to the inboard of deflector 11, and three water conservancy diversion hole is vertical equidistance and distributes, and three blast pipe 12 respectively with the water conservancy diversion hole intercommunication that corresponds, the quantity of blast pipe 12 inboard acoustical panel 13 is seven, and seven acoustical panel 13 are horizontal equidistance and the amortization hole has been seted up to the inboard of acoustical panel 13.
The working principle of the embodiment is as follows:
The air current is passed through cavity 14 and is made preliminary noise reduction by amortization cotton 15, because connecting pipe 6 is connected with gas outlet 2 through first ring flange 4 and second ring flange 5, therefore when the air current enters connecting pipe 6 from gas outlet 2, the noise of air current can be received the block of the inboard rubber sound insulation strip 16 in first ring flange 4 centre of a circle and the inboard in second ring flange 5 centre of a circle, after the air current enters buffer chamber 7 and contact with buffering step 8, and upwards climb gradually the buffering step 8 and slow down, reduce the shock wave and the vortex intensity of air current, reach the amortization effect, when the air current enters transfer chamber 10, the air current passes the guiding hole of guide plate 11 thereby disperses, and the air current enters the inside of corresponding blast pipe 12, when the air current passes the amortization hole of acoustical panel 13, because the sectional area of amortization hole reduces, the sound wave can scatter to more extensive region, this can lead to the path length that the sound wave propagates in the space, simultaneously, because of existence of amortization hole, the sound wave still can meet effects such as air and heat conduction viscosity in the propagation process, thereby further the intensity of sound wave.
