AI Technical Summary

Technical Problem

The insufficient utilization of the flow area of ​​the exhaust plate silencer of the air-cooled heat pump unit leads to excessively high local wind speed, which increases the noise generated by the airflow and affects the noise reduction effect.

Method used

A flow guide assembly, including flow guide vanes, fixed ribs, and fixed columns, is installed inside the silencer to adjust the flow field distribution, control the flow velocity within a suitable range, and reduce airflow regeneration noise.

Benefits of technology

By setting up the flow guide vane assembly, a uniform distribution of the flow field inside the muffler is achieved, reducing airflow regeneration noise and improving the noise reduction performance of the muffler.

Abstract

The utility model discloses an exhaust vane type silencer structure of an air-cooled heat pump unit, which is mounted above an exhaust fan component of the air-cooled heat pump unit and comprises an upper silencing insert, a lower plenum chamber and a flow deflector component arranged in the lower plenum chamber. The flow deflector assembly comprises flow deflectors, fixing ribs and fixing columns, the flow deflectors are at least used for adjusting flow field distribution in the silencer, and the fixing ribs are connected with the flow deflectors and the fixing columns. The flow deflector is used for adjusting the flow field of airflow entering the silencer insertion piece part, so that the flow field in the silencer is more uniform, the situation that airflow regeneration noise is increased due to the fact that the local wind speed is too high is avoided, and finally the actual noise reduction performance of the silencer is improved.
