The invention provides a heat exchange tube assembly, a heat exchanger and an air conditioner. The heat exchange tube assembly is suitable for an air conditioner, and includes a plurality of heat exchangers connected in series from end to end and sequentially arranged along the radial direction of the impeller of the fan of the air conditioner. Heat pipe group; each heat exchange tube group includes a plurality of heat exchange tube layers connected in series from end to end, and the plurality of heat exchange tube layers are arranged at intervals along the radial direction of the impeller; each heat exchange tube layer includes a plurality of heat exchange tube layers connected in series from end to end Heat exchange tube structure, multiple heat exchange tube structures are arranged at intervals around the axis of the impeller; the tube diameters of the heat exchange tube structures in each heat exchange tube group are the same; along the radial direction of the impeller and away from its axis, multiple heat exchange tube structures The tube diameter of the heat exchange tube structure in the tube group decreases gradually; or along the radial direction of the impeller and away from its axis, the tube diameter of the heat exchange tube structure in multiple heat exchange tube groups gradually increases, which solves the problem In the prior art, the heat exchanger cannot well adapt to the phase change state of the refrigerant, which results in a large pressure resistance loss when the refrigerant flows.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange tube assembly, a heat exchanger and an air conditioner. Background technique [0002] At present, the cylindrical cabinet air conditioners on the market have the problem of large air outlets and high positions, which makes most of the refrigerant flow from bottom to top concentrated on the upper part of the heat exchanger due to inertia, resulting in the air outlet of the indoor unit The phenomenon of large and uneven temperature deviation reduces the comfort experience level of consumers. [0003] Secondly, the heat exchangers of indoor units in the prior art mostly use large-diameter heat exchange tubes, which are arranged in a three-fold structure or a straight-line L-shaped structure with bent fins. The size is larger, the amount of refrigerant filling is larger, the cost is higher, the flow rate of the refrigerant in the heat exchange tube is small, th...
