Compressor exhaust silencer structure

Abstract

The invention discloses a compressor exhaust silencer structure which is applied to the technical field of compressors. The compressor exhaust silencer structure comprises a silencer and an exhaust pipe, wherein the silencer comprises a shell with an air inlet and an exhaust hole; the shell forms a silencing cavity between the air inlet and the exhaust hole; a clapboard for dividing the silencingcavity into a front silencing cavity and a rear resonant cavity is arranged in the shell; a clapboard through hole is formed in the clapboard; the exhaust pipe comprises a rear exhaust pipe connectedwith the exhaust hole; the rear exhaust pipe is provided with a necking throttle section matched with the clapboard through hole; and an airflow channel(s) for communicating the front silencing cavityand the rear resonant cavity is / are arranged on the clapboard and / or the rear exhaust pipe. According to the compressor exhaust silencer structure provided by the invention, an external silencer cavity structure is adopted, so that a performance of a compressor is improved; the rear exhaust pipe is provided with the necking throttle section so as to form inner exhaust throttle, so that the partsare less, the process is simple, and the difficulty of a production process and the material and process cost are reduced; and by adopting a resonance design of the rear resonant cavity and the airflow channels, the exhaust pulse of the compressor is reduced, and the matching sound quality is improved.

Description

technical field [0001] The invention is used in the technical field of compressors, and in particular relates to a compressor exhaust muffler structure. Background technique [0002] Compressor discharge pulsation is the main reason affecting the noise and vibration of the compressor. Because the compressor discharge temperature is higher than the suction problem, the heat in the discharge process is often transferred to the cylinder hole, resulting in a decrease in the compressor suction efficiency and the actual intake air volume. The reduction will affect the cooling capacity of the compressor and reduce the performance of the compressor. The exhaust pulsation is an important factor affecting the noise. The greater the exhaust pulsation, the greater the noise and vibration of the compressor, and the worse the noise when matching with the refrigerator. poor quality. Therefore, the current exhaust muffler structure has been gradually improved from the traditional molded mu...

AI Technical Summary

Problems solved by technology

[0007] 1. Drilling the throttle hole in the cylinder seat, the process is more complicated, and the processing and material costs are high

[0008] 2. When the high-temperature and high-pressure exhaust passes through the orifice, it dissipates heat to the cylinder hole, which makes the temperature of the intake cavity, the surface of the intake passage, the wall surface of the cylinder and the top surface of the piston rise, which easily heats the intake air and reduces the suction efficiency

[0009] 3. The process of fixing the throttle tube separately by the baffle plate is more complicated, and adding a throttle tube increases the cost

[0010] 4. The effect of reducing exhaust pulsation is poor
