Flow Rate is one of the common ways that is mostly used to select a “Water-Oil Cooler” cooling system with no specific reason.Flow Rate is unable to provide a specific measurement of heat. Cooling is a supplementary support to Hydraulic systems and not just a part of the Hydraulic Components. Therefore a design and selection work is required before purchasing. For cooling measurement, equilibrium between the heat created by an Hydraulic system and the heat dissipated by a cooling unit is required.
