Enhancement of the Performance of Hydraulic Power Pack by Increasing Heat Dissipation

Hydraulic power units are main driving components of driving system. Consisting mainly a motor, a reservoir and a hydraulic pump these units can generate a tremendous amount of power to drive any kind of hydraulic ram. Hydraulic power units are based on Pascal's law of physics drawing their power from ratios of area and pressure. Heating of hydraulic oil in operation is caused by inefficiencies. Inefficiencies result in losses of input power, which are converted to heat. If the total input power lost to heat is greater than the heat dissipated, the hydraulic system will eventually overheat. In this work an attempt is made to reduce the unwanted temperature of oil by changing the construction and material of the tank and providing fins over it. Finally the improvement of efficiency of power pack by reducing heat losses has been studied and analyzed.
