Abstract

The invention discloses a noise reduction connecting piece for a capillary tube and an evaporator and a refrigerating device, and belongs to the field of refrigerating devices. The noise reduction connecting piece comprises a connecting tube, and the connecting tube is filled with porous materials. By filling the connecting tube with the porous materials, the impact force of refrigerants on the tube wall can be buffered, and structural vibration noise of a pipeline is reduced; bubbles can also be dispersed, the formation of large bubbles is prevented, and bubble bursting sound is reduced; andas sound absorption materials, the porous materials can absorb all kinds of generated noise. The noise reduction connecting piece in the embodiment carries out noise reduction treatment on refrigerantnoise from three aspects of pipeline vibration noise, bubble bursting sound and jet noise erupting noise and plays a good vibration and noise reduction effect. The invention further provides a refrigerating device including the noise reduction connecting piece, the refrigerant noise is effectively reduced, the sound quality is improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a noise-reducing connection piece between a capillary tube and an evaporator and a refrigeration device. Background technique [0002] For the refrigeration system, the state of the refrigerant constantly changes in the refrigeration system pipeline, and the flow inside the condenser and evaporator is a two-phase flow, while the flow in the capillary is more complicated. At the inlet end of the capillary tube, it is generally a supercooled liquid single-phase flow, and then enters a two-phase flow state. At the outlet end of the capillary tube, the flow rate of the gaseous refrigerant may reach the local sound speed, and the flow rate of the refrigerant liquid at the outlet end is the same as There is a certain difference in the flow velocity of the gaseous refrigerant, and this state is the so-called "choked" state. The inhomogeneous mixture of gas and liquid at t...
