The application discloses an air conditioner outdoor unit and an air conditioner. The air conditioner outdoor unit is provided with a damping device on a refrigerant pipeline. The damping device comprises a first component, a connecting rod and a second component. The first component is arranged on the refrigerant pipeline. The connecting rod is arranged on the first component. The second component is arranged on the connecting rod. The second component and the first component and the connecting rod can move relatively. One of the first component and the second component is a conductor, and the other is a magnet. When the refrigerant pipeline vibrates and drives the first component and the connecting rod to vibrate, the relative movement occurs between the first component, the connecting rod and the second component, so that the conductor generates an induced current. The magnetic field generated by the induced current is opposite to the magnetic field of the magnet, which can prevent or slow down the movement of the first component to reduce the vibration of the refrigerant pipeline. The induced current in the conductor also causes the conductor to heat, so that part of the kinetic energy of the refrigerant pipeline is converted into electric energy and heat energy, further consuming the kinetic energy of the refrigerant pipeline, and realizing the damping of the refrigerant pipeline.
