The synthesis energy saving ratio of the independent cooling system of cooling system and fluid motor-driven fan is concentrated all below 5%, moreover, warm
The heat for spending high radiator is possible to pass to the low radiator of temperature, can not also distinguish the radiating of the different medium of radiator
Demand radiates to it, is also only that radiating of indivedual radiatings such as hydraulic oil is independent on some heavy-duty machines, adopts
Radiated with the mode of fluid motor-driven fan.Independent cooling system using multiple fluid motor-driven fans is right respectively
The mode of different medium radiating, but cost is very high.
In view of this, the present inventor furthers investigate to engineering mechanical radiating system, proposes a kind of more preferable energy-conservation of realization, noise reduction
Engineering machinery intelligent heat dissipation management system and method, this case thus produce.
