Oil Cooler Capacity Calculations

Calculation of preliminary cooler capacity.

Oil cooler capacity calculations. Therefore our product selection is continuously changing. This is almost impossible to calculate but can be estimated based on the type of system and the components used. Q 999 78kg m3 x 0 0995m3 s x 4 19kj kg k x 12 c 273 15k 6 c 273 15k we add 273 15k to the celcius to convert it to units of kelvin. Using the energy equation of q ṁ x cp x δt we can calculate the cooling capacity.

Iso vg 68 oil flowing at 40 gpm and a desired cooling capacity qr 40 hp. Oil cooler with ac motor 400v oil cooler with hydraulic motor. Areas we are continuously seeking to improve performance include cooling capacity noise level pressure drop and fatigue. So the oil cooler must be capable of rejecting at least 20kw of heat to maintain an acceptable and stable oil temperature.

The next thing to consider is the native efficiency of the system. Inlet oil temperature to 140 f and inlet water temperature tw 100 f. The specific heat capacity cp is measured in units of kj per kg per kelvin. Oil cooler sizing calculator.

Heat dissipation from hydraulic oil tanks valves pipes and hydraulic components is less than a few percent in standard mobile equipment and the cooler capacity must include some margins.
