Abstract

The invention discloses an internally-threaded evaporation heat exchange tube inlayed with a metal wire mesh on the inner surface. The internally-threaded evaporation heat exchange tube comprises a tube body provided with an inlet end and an outlet end, wherein a plurality of linear ribs peripherally distributed at intervals and extending in the axial direction of the tube body and linear channels formed among the linear ribs are arranged on the inner surface of the tube body, at least one layer of cylindrical metal wire mesh is arranged in the tube body, and the peripheral face of the metal wire mesh is in contact with the tops of the linear ribs to cover the linear channels, so that a channel separated from a central tube cavity of the tube body is formed between the metal wire mesh and the linear channels. The heat exchange efficiency of the threaded heat exchange tube can be further improved.

Description

technical field [0001] The invention relates to a heat exchange tube, in particular to an internal thread evaporation heat exchange tube with wire mesh embedded on the inner surface. Background technique [0002] Internally threaded tubes are highly efficient evaporative heat exchange tubes that are widely used at present. The use of this kind of internal thread evaporative heat exchange tube in the evaporator of general refrigeration air conditioners can reduce the volume, improve the heat exchange effect, and improve the efficiency of the refrigerator system. In order to continue to improve the heat exchange efficiency of the internally threaded pipe, new forms of fin shapes have been introduced on the basis of the original internally threaded pipe in recent years. Chinese patent: CN02232596.4 proposes that on the helical teeth in the pipe, along the tooth top ridge Cut-off ridge grooves with regular / irregular spacing are used to increase the heat transfer area, thereby i...
