Abstract:
A diesel locomotive power system, comprising a diesel generator set (1), a cooling system (2) and a swirling device (3), wherein the cooling system comprises a cooling fan (24); the swirling device is horizontally arranged beside the diesel generator set and is in communication with an exhaust pipe (117) of the diesel generator set; the cooling fan is located below the swirling device; an exhaust outlet (27) is provided above the swirling device, and a through hole (33) is provided in the middle of the swirling device; the cooling system is in communication with the through hole and the exhaust outlet, and an exhaust side of the cooling fan faces the swirling device; and a low-pressure region is formed between the cooling fan and the through hole of the swirling device. According to the system, the low-pressure region is formed above the cooling fan, such that the power required by the cooling fan can be reduced, thereby reducing the noise of the cooling fan, and achieving an energy-saving effect.
