Embodiment 1
[0018] Such as figure 1 As shown, a cooling device for an APU system module, the APU system includes an engine, a supercharger, a thermostat, a water pump and a generator, and the cooling device includes an engine cooling water circuit, an engine intake cooling air circuit, a generator cooling Waterway and APU controller 5, the engine cooling waterway includes engine radiator and engine cooling electronic fan, the water inlet of the engine radiator is connected with the thermostat, the water outlet of the engine radiator is connected with the water pump, and the engine is connected with the water pump and the thermostat Between, the water inlet and the water outlet of the engine radiator are respectively provided with the engine inlet water temperature sensor 2 and the engine outlet water temperature sensor 1, and the engine cooling electronic fan, the engine inlet water temperature sensor 2 and the engine outlet water temperature sensor 1 are respectively controlled with the A...
Embodiment 2
[0023] This embodiment discloses a cooling method for an APU system module, such as figure 1 Shown is the control principle diagram of this method. The cooling method is based on the cooling device described in Embodiment 1, S01), engine water cooling, the APU controller monitors the engine outlet water temperature through the engine outlet water temperature sensor, and adjusts the engine through hierarchical control. Cool the speed of the electronic fan and water pump so that the engine is in the best working condition; S02), the engine is air-cooled, the APU controller detects the intake air temperature of the intercooler through the intercooler intake temperature sensor, and adjusts the intercooler through hierarchical control The speed of the electronic fan of the generator can reduce the intake temperature of the engine when the engine is working at low speed, and improve the efficiency of the engine; S03), the generator is water-cooled, the APU controller monitors the mot...
