Oil coolers, motor cooling, gearing and steering mechanism
Oil coolers support also the water cooler as they divert a part of the heat.
During the flow through the different components the oil absorbs heat. The heated oil circulates, partly via oil pump within the circuit. To reach the ideal working temperature of the oil and the connected lubrication the fluid is conducted through the oil cooler.
This principle is applied in the field of the motor cooling for the gearing and steering mechanism.
