Oil Cooler Capacity Calculations

Oil cooler with ac motor 400v oil cooler with hydraulic motor.

Oil cooler capacity calculations.

The next thing to consider is the native efficiency of the system. Minimum cooler capacity ecooler 0 25ediesel. Using the energy equation of q ṁ x cp x δt we can calculate the cooling capacity. Oil cooler with dc motor 12v 24v.

The specific heat capacity cp is measured in units of kj per kg per kelvin. Iso vg 68 oil flowing at 40 gpm and a desired cooling capacity qr 40 hp. A continual desire for more cost efficient and environmentally friendly hydraulic systems requires continuous development. Areas we are continuously seeking to improve performance include cooling capacity noise level pressure drop and fatigue.

Calculation of preliminary cooler capacity. Inlet oil temperature to 140 f and inlet water temperature tw 100 f. Therefore our product selection is continuously changing. 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.

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.
