The hydraulic oil air cooled radiator is the cooling device of the hydraulic system, which is mainly used to cool the hydraulic oil. Because the hydraulic oil will produce heat when the system works, if the oil temperature is not reduced to the temperature required for normal work, the oil will deteriorate and coking, affecting the work of the whole system.

For hydraulic oil, first of all, the hydraulic device should meet the requirements of liquid viscosity at the working temperature and starting temperature, because the viscosity change of lubricating oil is directly related to the hydraulic action, transfer efficiency and transfer accuracy, but also the viscosivity and shear stability of the oil should meet the various needs put forward by different uses.

Therefore, the hydraulic oil will produce a lot of heat energy in the process of being compressed to do work. This part of heat energy will affect the stability of the hydraulic system, accelerate the aging of seals, reduce equipment efficiency and other adverse effects. Therefore, it is necessary to cool the hydraulic oil. The cooling way can make the hydraulic oil air-cooled radiator can also be the tubular water-cooled heat exchanger.

The hydraulic oil air-cooled radiator uses the natural wind to cool the hydraulic oil. It is simple to install and the oil temperature can only be above the ambient temperature. The tubular water-cooled heat exchanger is through the indirect contact of water and hydraulic oil in the pipe wall to exchange heat, the need to lay pipelines and ensure water circulation, the temperature of water is low enough to keep the oil temperature stable below the ambient temperature. Specific choose the structural form of radiator, should choose according to oneself specific condition.
