1. A fracturing apparatus comprising:
a plunger pump configured to pressurize a fracturing fluid to form a high-pressure fracturing fluid;
a turbine engine coupled to the plunger pump and configured to drive the plunger pump;
an auxiliary unit comprising an electric motor unit, the auxiliary unit being configured to provide the fracturing apparatus with at least one of a turbine-engine start-up assistance function, a lubrication function, a cooling function, and an air supply function; and
a power supply electrically coupled to the electric motor unit of the auxiliary unit to provide a power source;
wherein a cooler of the auxiliary unit for providing the cooling function is disposed above the plunger pump with an upward inclination angle between 10 to 30 degrees such that cooling air discharge flows upward and towards an exhaust muffler of the turbine engine.
