The invention belongs to the technical field of aviation systems, and discloses an aviation high-speed generator cooling system and a control method.The main oil pipeline is provided with a fuel pump, and the auxiliary oil pipeline is provided with a radiator; the pressure-bearing heat exchanger is connected with the oil tank through a main oil pipeline and an auxiliary oil pipeline. The pressure-bearing type heat exchanger is further connected with the turbine engine through a conveying pipeline. The pressure-bearing exchanger comprises a heat pipe and is connected with the high-speed generator through the heat pipe; the fuel pump is used for pumping out fuel in the fuel tank and transferring the fuel to the pressure-bearing heat exchanger through the main oil pipeline; the pressure-bearing heat exchanger is used for carrying out heat exchange on fuel oil in the main oil pipeline and the high-speed generator and transferring a first part of fuel oil subjected to heat exchange to the turbine engine through the conveying pipeline; and the second part of fuel oil subjected to heat exchange is transferred back to the oil tank through the auxiliary oil pipeline. The weight of the cooling system can be reduced, the unmanned aerial vehicle can be carried more conveniently, and the cooling function can be achieved when the turbine engine stops.
