The hole pipe is perpendicular to the flat plate or is obliquely arranged.

The support is equipped with at dull and stereotyped periphery, through support and shell inner wall fixed connection.

The utility model also provides a compressor, it includes that the aforesaid falls the casing of making an uproar, is equipped with the core in the casing, is equipped with the silencer of breathing in on the core, and the air inlet of the silencer of breathing in is just right the breathing pipe, the honeycomb orifice plate sets up between the air inlet of breathing pipe and silencer of breathing in, air inlet department is equipped with a honeycomb orifice plate.

The working principle of the utility model is as follows: a honeycomb pore plate is arranged between the air suction pipe of the compressor shell and the air suction muffler. The honeycomb pore plate has larger flow resistance, overcomes viscous resistance to do work when airflow passes through, and can generate certain pressure loss, so that the mutual friction among fluid molecules is intensified, and the purpose of effectively eliminating noise is achieved. The honeycomb pore plate is provided with the pore pipes, when the pipe diameters and the pipe lengths of the pore pipes are combined and matched by different parameters, the length and the volume of the flow channel are changed, the air suction noise of a specific frequency band can be improved by controlling the parameters, and the aim of improving the noise elimination quantity is fulfilled.

Compared with the prior art, the utility model has the following advantages: 1. the airflow pulsation at the port of the air suction pipe of the compressor is improved, and the air suction noise is reduced; 2. the air current flows orderly when passing through the honeycomb holes, the problems of pressure loss and cold quantity reduction caused by disordered flowing states of the refrigerating medium are effectively solved, and the refrigerating capacity of the compressor is improved.
