Title:

NOISE REDUCTION DEVICE AND REFRIGERATION DEVICE HAVING SAME

Document Type and Number:

WIPO Patent Application WO/2022/083189

Kind Code:

A1

Abstract:

The present utility model provides a noise reduction device, comprising an outer connecting pipe. The outer connecting pipe comprises a first end connected to a capillary tube and a second end connected to an evaporator; a plurality of porous wire meshes distributed at intervals are provided in the outer connecting pipe; the side edges of the porous wire meshes abut against the inner wall surface of the outer connecting pipe; and from the first end to the second end, the pore diameters of the plurality of porous wire meshes gradually decrease. The provision of the plurality of porous wire meshes having gradually changed pore diameters enables bubbles formed at a discharge port of the capillary tube to be gradually divided and recombined into small bubbles from large bubbles when passing through the noise reduction device, thereby reducing the noise caused by bubble breakage.
