Oil-Air -Cooling Units
FUNKE oil/ air cooling units are based on the system
Längerer & Reich. The consequent development of this
system by FUNKE resulted in up to now 17 OKAN standard sizes in one or multi-pass design with a maximum
heat dissipation of 6,2 kW/K, all available in line with the
demand of the respective application. This wide variety
of standard units allows for flexible serving most of the
applications. For plant engineering and series producers regularly project-specific special constructions are developed.
Design and Function
Basic element is an aluminium cooler in bar and plate construction. The oil tubes are fitted with turbulence elements to guarantee an optimum heat transfer. Depending on the volumetric flow rate, the medium to be cooled flows through the cooler either in one pass or multiple passes and is cooled by the stream of ambient air produced by the fan.
The fan is mounted behind the cooler so that the standard fan mode of operation is suction, which means that the cooling air streams from the cooler towards the motor.
The fan can also be supplied in pressure mode, if so specified upon ordering. The oil and air fins, fan blades and motor power are carefully engineered and dimensioned to achieve an optimum degree of heat dissipation.
