摘　　要：液压驱动风扇冷却系统分机液控制和电液控制两类,它们都具有风扇转速可调的特点,而且风扇转速与发动机转速无关,只与散热量、被冷却介质(如水、液压油等)的温度以及环境温度有关,能保证被冷却介质恒温工作,能减少发动机磨损,降低排放。Cooling systems with hydraulically driven fans are divided into two categories, mechanical-hydraulic control and electro-hydraulic control. They all feature adjustable fan speeds and the fan speeds bear no relations with engine speeds, but are only related to volume of heat radiation, temperature of cooling medium (such as water, hydraulic oil and etc.) and ambient temperature. The systems can assure the cooling medium to work in a consistent temperature and can lessen engine wear and reduce engine emission.
