Problems solved by technology

[0002] At present, the auxiliary power unit of the automobile, that is, the APU system, generally adopts a mechanical cooling method. In this cooling method, the speed of the fan and water pump is affected by the speed of the engine, which is likely to cause poor heat dissipation at low speeds, and overheating of the engine in winter. Waiting for failures. In addition, this mechanical cooling method is too limited by the engine, so it can only be arranged at the front end of the engine pulley, which greatly restricts the layout of the vehicle. In addition, this cooling method also has the disadvantages of high noise and high power consumption.

Abstract

The invention discloses an APU system module cooling device and a method. The cooling device comprises an engine cooling water circuit, an engine intake cooling air circuit and an engine cooling water circuit, and the three cooling modules are of independence and noninterference; in addition, a traditional mechanical water pump is changed to a controllable water pump, so that the power consumption of a cooling system under the low speed working condition of an APU assembly is reduced; a traditional mechanical fan is changed to an electronic fan which is controlled in a blocking manner; the series connection of traditional cooling modules is changed into parallel connection, and the cooling modules are additionally provided with water inlet and outlet temperature sensors and air inlet and outlet temperature sensors; the traditional mechanical water pump is changed to the controllable electronic water pump and an electric control silicone oil pump. The cooling method is used for separately controlling engine cooling, engine intake cooling and generator cooling, and the speed of the electronic fan and the water pump is controlled by a control unit through the temperature sensors, and the system is controlled within the optimal working temperature range.
