The invention relates to a heat exchange tube, a heat exchanger and a heat pump unit. The heat exchange tube comprises a tube body (1) and fins (2) arranged on the outer wall of the tube body (1). Channels are formed between the adjacent fins (2), and oppositely extending fin table portions (22) are disposed on the side walls of the adjacent fins (2). The oppositely extending fin table portions (22) are provided with overlapping sections, and the channels form areas communicating with each other on the upper and lower parts of the fin table portions (22). The heat exchange tube can simultaneously achieve the evaporation and condensation performance of the heat exchange tube, and reduces the performance attenuation of the heat exchange tube under the conditions of evaporation and condensation; and the opposite fin table portions are provided with the overlapping sections, the stability of upper and lower cavities can be maintained structurally, and stable heat exchange performance is achieved.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange tube, a heat exchanger and a heat pump unit. Background technique [0002] Heat pump units use clean energy, which can be used for both cooling and heating, and are more and more widely used. At this stage, heat pump units mostly use dry heat exchangers, and the refrigerant evaporates or condenses in the tubes for heat exchange. However, dry heat exchangers have the problem of low heat exchange efficiency, so flooded heat exchangers are increasingly used in heat pump units to improve the energy efficiency ratio of the units. [0003] In the flooded heat exchanger, the refrigerant evaporates or condenses on the outside of the tube to exchange heat. It is required that the flooded heat exchanger can realize both evaporation and condensation functions. When switching between cooling and heating states, the evaporation and condensation should be as low as possi...
