The invention relates to an external cooling system of a water-cooled engine. The system involves an unmanned aerial vehicle body, an unmanned aerial vehicle engine and the external cooling system arranged on the unmanned aerial vehicle body, wherein the external cooling system involves a plurality of condensation pipes, the condensation pipes are hollow to form cooling cavities, the cooling cavities are filled with liquid condensing agents, the plurality of cooling cavities communicate, the condensation pipes are hollow pipes and form air cavities, the cooling cavities are annular, and a plurality of cooling fins are arranged on the inner walls of the air cavities. The external cooling system is arranged in the unmanned aerial vehicle body and is used for reducing heat generated by the unmanned aerial vehicle engine; and the condensation pipes in the external cooling system are arranged in the unmanned aerial vehicle body, heat generated by an unmanned aerial vehicle is transmitted to the condensation pipes and the liquid condensing agents in the condensation pipes, opposite wind generated in the flying process of the unmanned aerial vehicle takes away the heat of the condensation pipes, and therefore the effect of reducing the temperature of the unmanned aerial vehicle is achieved.
