Abstract

The invention relates to a heat exchange tube, a heat exchanger and an air conditioner. The heat exchange tube comprises a tube body (1), fins (2) are arranged on the outer wall of the tube body (1) in the circumferential direction, protruding parts are arranged on the partial circumferential region of the fins (2), and a smooth fin segment (6) is formed in the peripheral region of the rest of thefins (2). According to the heat exchange tube, the thickness of liquid film adhered to the surface of the fins can be reduced by arranging the protruding parts on the fins, the heat exchange surfacearea is increased, the structure can enhance the local phase change heat capacity of the structure; meanwhile, the smooth fin segment can reduce the liquid flowing resistance and enable the liquid tosmoothly flow out, so as to prevent the liquid film from accumulating on the surface of the fins so as to reduce the circumferential heat exchange area and increase the heat resistance, so that the overall heat exchange effect of the heat exchange tube is comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchange tube, a heat exchanger and an air conditioner. Background technique [0002] In the refrigeration and air-conditioning industry, water-cooled condensers have developed rapidly due to their compact structure and wide applicability. Most of the water-cooled heat exchangers are shell-and-tube heat exchangers. In the condenser, a factor that has a relatively large impact on the heat transfer is the performance of the heat exchange tubes in the shell. During the heat exchange process of the condensing tube, the gaseous refrigerant outside the condensing tube exchanges heat with the water inside through a phase change. Since the thermal resistance of the condensing tube mainly exists outside the tube, according to the principle of weak side strengthening, strengthening the outside of the tube is obvious. It is especially important that the external thermal res...
