A muffler assembly for refrigeration plant

The utility model discloses a muffler assembly for refrigeration plant, including first tubular metal resonator, second tubular metal resonator, at least, be equipped with a recess on the outer wall of first tubular metal resonator, this recess along the axial extension of first tubular metal resonator, the second tubular metal resonator at least some be embedded into in the recess, the at least partly wall with the recess partly at least of the outer wall of second tubular metal resonator coincide, and the second tubular metal resonator is fixed integratively with first tubular metal resonator. The utility model discloses the refrigerant gasifies in being favorable to helping the muffler, input evaporimeter end refrigerant temperature reduce, improves the heat exchange performance. 本实用新型公开了种用于制冷设备的回气管总成，包括第金属管、第二金属管，所述第金属管的外壁上至少设有个凹槽，该凹槽沿着第金属管的轴向延伸，所述第二金属管的至少部分嵌入到所述凹槽中，第二金属管的外壁面的至少部分与凹槽的至少部分壁面吻合，第二金属管与第金属管固定成体。本实用新型有利于帮助回气管中制冷剂气化；输入蒸发器端制冷剂温度降低，提高热交换性能。
