Jiangsu New Silver Leaf Transmission Ltd gearbox air cooler effect works as follows:

Air cooler: for cooling the gearbox oil. The air cooler by an electric motor, high-performance axial fans, heat sinks and temperature control valve, the bypass valve. Its working principle shown in Figure 2, that is, when the gearbox oil temperature reaches 55 ℃, temperature control valve is closed, cooler air began to work automatically, lubricating oil cooler and then into the wind to the gearbox forced lubrication; when oil when the pool temperature dropped to 45 ℃, fan cooler automatically stop working, the lubricant directly through the thermostatic valve into the gearbox forced lubrication. When the pressure reaches cooler 6bar, the bypass valve is open, without lubricating oil directly into the cooler to the gearbox.
