Background

In the refrigeration system of the refrigeration appliances such as the refrigerator and the freezer which are common at present, a capillary tube is usually adopted between a condenser and an evaporator for throttling and pressure reduction. The capillary tube makes the refrigerant decompress and regulate the flow rate and then enters the evaporator, the pressure in the capillary tube drops suddenly, the liquid expands suddenly, the refrigerant is converted into low-temperature and low-pressure mist and enters the evaporator, a large amount of bubbles are generated in the phase change process, and the pipeline vibration is caused. And as the pressure drops, these bubbles will grow until they collapse, further increasing the vibration of the capillary tube, creating a burst noise. In the process that the noise is transmitted outwards through the vibration of the capillary tubes, the capillary tubes with small spacing and the evaporator tubes collide with each other, and the noise is increased continuously; even resonance phenomena between the pipes can occur, further increasing noise.

Above-mentioned multiple noise's stack, user's intuitional experience refrigerator can send great noise promptly, and it is extremely poor to use experience.

For the above noise problem, a common noise reduction method is to attach damping mastic or add a noise reduction structure at the capillary. However, the vibration-damping daub is easy to harden at low temperature, the effect of reducing vibration is greatly reduced, and the problem that the process attachment is not in place in actual operation exists. When the noise reduction structure is adopted, the length of the pipeline is often greatly increased, or the noise reduction structure occupies a large space, most of the noise reduction structure is positioned between the air duct and the inner container, the space is very limited, the space in the refrigerator is also limited, too much space is occupied, the space utilization efficiency of the refrigerator is influenced, the pipeline is disordered due to the increase of the length of the pipeline, resonance is easily caused, and the vibration reduction effect is greatly reduced. There is currently no better solution for noise reduction at this location.
