Heat exchange tube assembly and condensing evaporator

The invention discloses a heat exchange tube assembly and a condensation evaporator, and relates to the field of heat exchange tubes. The heat exchange tube assembly comprises a heat exchange tube body and further comprises a sliding groove formed in the heat exchange tube body. The sliding rings are connected into the heat exchange tube body in a sliding mode, and the sliding rings are matched with the inner diameter of the heat exchange tube body; the mounting frame is fixedly connected into the sliding ring, a rotating shaft is rotationally connected to the mounting frame, and rotating fan blades are fixedly connected to the rotating shaft; the plurality of groups of elastic ropes are used for connecting the plurality of groups of sliding rings; through the arrangement of the sliding ring, water scale in the heat exchange pipe can be cleaned, meanwhile, the cleaned water scale can automatically fall off, the heat exchange effect is improved, and meanwhile the heat exchange pipe can be conveniently used for
