COOLING DEVICE FOR A HYBRID BUS, CAPABLE OF SIMULTANEOUSLY COOLING AN ENGINE AND A HYBRID COMPONENT BY USING ONE COOLING FAN

摘要

PURPOSE: A cooling device for a hybrid bus is provided to cool an engine and a hybrid unit mounted on the hybrid bus with one cooling fan.;CONSTITUTION: A cooling device for a hybrid bus comprises a radiator module(10), a cooling fan(20), and a control unit(70). The radiator module cools a hydraulic fluid discharged from a hydraulic motor(61); a coolant discharged from a hydraulic unit(40) and an engine(30); and a refrigerant discharged from an air conditioner(50). The cooling fan is included in the radiator module in order to supply external air and is rotated by the hydraulic motor. The control unit controls rotation of the cooling fan.;COPYRIGHT KIPO 2013;[Reference numerals] (12) Engine radiator; (13) Hybrid radiator; (14) Air conditioner heat exchanger; (15) Oil cooler; (30) Engine; (31) Engine water pump; (40) Hybrid unit; (41) Hybrid water pump; (50) Air conditioner; (61) Hydraulic motor; (62) Oil tank; (63) Hydraulic pump; (70) Control unit; (71) Water temperature sensor; (72) Outdoor temperature sensor; (AA) Air
