Heat exchanger assembly, air conditioner outdoor unit and air conditioner

The utility model discloses a heat exchanger assembly, an air conditioner outdoor unit and an air conditioner. The heat exchanger assembly comprises a first heat exchanger; a main body of the flow divider is located at one end of the first heat exchanger, and a second port of the flow divider is connected with a first port of the first heat exchanger; a main body of the current collector is located between one end of the first heat exchanger and a main body of the flow divider, and a first port of the current collector is communicated with a second port of the first heat exchanger. According to the heat exchange assembly, the main body of the flow collector is arranged in the area between one end of the first heat exchanger and the main body of the flow divider, the space is utilized to the maximum extent, in this way, the space occupied by the area where the flow collector and the flow divider are arranged can be reduced, and therefore the heat exchanger assembly is more compact in structure and smaller in occupied space.
