Piezoelectric phonon crystal type anti-vibration pipeline, anti-vibration method and air conditioner

Abstract

The invention provides a piezoelectric phonon crystal type anti-vibration pipeline, an anti-vibration method and an air conditioner. The piezoelectric phonon crystal type anti-vibration pipeline comprises an anti-vibration pipeline body and external circuits, wherein the anti-vibration pipeline body comprises at least one piezoelectric circular tube and at least one metal circular tube, the piezoelectric circular tubes and the metal circular tubes are periodically arranged, and the external circuits are connected with the piezoelectric circular tubes. According to the anti-vibration pipeline,the energy consumption performance of a piezoelectric material and the band gap characteristic of a phonon crystal are combined, so that the anti-vibration pipeline is provided with the vibration reduction frequency band, moreover, the vibration reduction frequency band is adjustable and can be applicable to inhibition of the vibration sources of different frequencies, the vibration transmitted onthe pipeline can be greatly inhibited, the vibration stress on the pipeline and the radiation noise generated by the vibration can be reduced greatly, and then the quality of a product and the user experience are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a piezoelectric phonon crystal type anti-vibration pipeline, an anti-vibration method and an air conditioner. Background technique [0002] At present, the compressor vibration of the air conditioner, especially the low-frequency vibration, is a prominent problem in the industry. The vibration of the compressor will be transmitted to the air conditioning pipeline to cause pipeline vibration, and the vibration will generate vibration noise, which seriously affects the user experience. The vibration and noise problem is also a complaint from users. main content. In addition, pipeline vibration will cause alternating stress on the pipeline. The greater the stress, the more prone to failure behaviors such as fatigue fracture in the air conditioning pipeline, which is a major factor affecting the service life of the air conditioner. [0003] At present, controlling the vibra...

AI Technical Summary

Problems solved by technology

In addition, pipeline vibration will cause alternating stress on the pipeline. The greater the stress, the more prone to failure behaviors such as fatigue and fracture in the air conditioning pipeline, which is a major factor affecting the service life of the air conditioner.

[0003] At present, controlling the vibration stress of pipelines is a difficult problem in the design and development of air conditioners. At present, most of the vibration reduction measures are to increase pipe clamps, add counterweights, and add damping blocks, etc., mainly to avoid vibration by adjusting its natural frequency. Stress, these measures have limited damping effects, will add multiple processes, increase manufacturing costs, and reduce manufacturing efficiency
