Heat exchange tube assembly, fabrication method thereof and refrigerator
The present invention provides a heat exchange tube assembly, a fabrication method thereof and a refrigerator, wherein the heat exchange tube assembly includes a heat exchange tube group, the heat exchange tube group includes a capillary tube and a gas return tube which come into contact with each other, and the heat exchange tube assembly further includes a vacuum tube with which a periphery of the heat exchange tube group is sleeved; heat transfer paths, such as heat conduction, heat convection, or the like, can be eliminated.
1 . A heat exchange tube assembly, comprising a heat exchange tube group, the heat exchange tube group comprising a capillary tube and a gas return tube which come into contact with each other, wherein the heat exchange tube assembly further comprises a vacuum tube with which a periphery of the heat exchange tube group is sleeved,
further comprising a support for fixing the heat exchange tube group in the vacuum tube,
the support comprises a support sleeve with which the periphery of the heat exchange tube group is sleeved and a plurality of support sheets located on a side of the support sleeve facing an inner wall of the vacuum tube,
wherein a section of the support sleeve is circular, and an outer diameter of the support sleeve is less than an inner diameter of the vacuum tube,
wherein at least two supports are provided and distributed in the vacuum tube at intervals along an axial direction of the vacuum tube.
2 . The heat exchange tube assembly according to claim 1 , further comprising a getter and/or a drying agent provided in the vacuum tube.
3 . The heat exchange tube assembly according to claim 1 , wherein the gas return tube and the capillary tube are arranged side by side.
4 . A refrigerator, comprising the heat exchange tube assembly according to claim 1 .
