Abstract

The invention provides a heat exchange tube, a heat exchanger and an air conditioner. The heat exchange tube is characterized in that first fins and second fins are arranged on the outer wall surfaceof a tube base body, each first fin comprises a fin root part perpendicular to the outer wall surface of the tube base body and a fin part parallel to the outer wall surface of the tube base body, each second fin is arranged on the upper part, covered by each fin part, of the tube base body, the tail end of each second fin penetrates out of each fin part, and each fin part is provided with a firstnotch part for the second fin to penetrate through. According to the heat exchange tube, the heat exchange area outside the heat exchange tube is remarkably increased, due to the design that the first notch parts extend upwards from the tube base body and penetrate through the first fins, the machinable space of the surface of the heat exchange tube is fully utilized, under the refrigeration working condition, a semi-closed structure formed by the first fins is beneficial to evaporation of a liquid refrigerant, the second fins increase the uneven degree of the surface to strengthen heat exchange, and under the heating working condition, the second fins can rapidly puncture a condensate film, and condensate can be rapidly discharged to the outer wall face of the tube base body.

Description

technical field [0001] The disclosure belongs to the technical field of heat exchange, and in particular relates to a heat exchange tube, a heat exchanger and an air conditioner. Background technique [0002] In the central air-conditioning water-cooled heat pump heat exchanger, the heat transfer coefficient in the tube is improved by strengthening the internal thread structure in the tube. Due to the limitations of the existing in-tube extrusion molding process that can be processed economically on a large scale, the improvement of the in-tube efficiency of the heat exchange tube is limited. Outside the heat exchange tubes, due to the particularity of the switchable cooling and heating conditions of the heat pump working condition, it is required that the outer fin type of the heat exchange tube has a structure that can satisfy both enhanced evaporation and enhanced condensation. According to the existing theory of evaporation and condensation, the fin shape that strengthe...
