Problems solved by technology

[0003] Most of the existing outdoor units have a fan on one side of the refrigerant heat exchange tube, and the fan rotates to blow the air into the outdoor unit and contact the refrigerant heat exchange tube, so that the air contacts the refrigerant heat exchange tube and transfers the heat in the air to the refrigerant heat exchange tube. In the refrigerant in the refrigerant heat exchange tube, the outdoor unit is used as a heat exchanger to absorb heat from the outdoor air, but it is difficult to discharge the air after absorbing heat, and the air after absorbing heat is not easy to discharge, and the air fluidity in the outdoor unit is poor, resulting in the efficiency of heat exchange Low, and the fan blades are large in size, and the noise is high during high-speed rotation; in the process of using in hot weather, the outdoor unit acts as a heat exchanger to absorb heat from the outdoor air, and the air source heat pump has a high workload, but the current There is technology and there is no suitable technical method for rapid heat dissipation

Description

technical field [0001] The invention relates to the technical field of an air energy heat pump outdoor unit, in particular to an air energy heat pump outdoor unit and a method for facilitating rapid heat dissipation. Background technique [0002] The air source water heater works according to the "reverse Carnot" principle. Specifically, the "outdoor unit" acts as a heat exchanger to absorb heat from the outdoor air, heat the low-boiling point working medium (refrigerant) and evaporate it, and the refrigerant vapor is compressed. The machine compresses and heats up and enters the water tank, releases heat to the water in it and condenses and liquefies, then throttles down and lowers the temperature and returns to the outdoor heat exchanger to enter the next cycle. [0003] Most of the existing outdoor units have a fan on one side of the refrigerant heat exchange tube, and the fan rotates to blow the air into the outdoor unit and contact the refrigerant heat exchange tube, so...
