Be separated by operation and internal-combustion engine circulating water pump and cooling fan, no matter the rotating speed of internal-combustion engine height and whether turning round then, circulating water pump and cooling fan all can independently be regulated, thereby under internal-combustion engine different running state and ambient temperature conditions, all can realize the best fit of cooling work and internal combustion engine operation state.Promptly work as internal combustion engine under the situation that the big load of low speed is exported and ambient temperature is very high; although internal-combustion engine rotational speed is not high; heating value is very big; but circulating water pump and cooling fan all can quicken operation; improved the cooling effect of cooling unit; internal-combustion engine is dispelled the heat as early as possible, and the phenomenon of having avoided internal-combustion engine to shut down because of overheated initiating failure occurs.When cold area is driven a vehicle in the winter time, the rotating speed of cooling fan and circulating water pump is reduced until shutdown, to exceed heat radiation.So just can make internal-combustion engine reach appropriateness heat radiation or under keeping warm mode, move, thus the fuel consumption of having avoided internal-combustion engine under worst cold case, to increase.
Because operation and the internal-combustion engine of this cooling unit are separated, and only when the operation of internal-combustion engine needs, just put into operation and dispel the heat in right amount, so can save suitable operation energy consumption, reached purpose of energy saving.
The utility model can make circulating water pump and the cooling fan in the internal-combustion engine cooling unit realize the stepless speed regulation operation, circulating load and air output with accurate adjusting cooling water, thereby alleviate and dwindled the fluctuating temperature amplitude of cooling circulating water to greatest extent, make internal-combustion engine can stable operation on optimum working temperature point.
