The Laminova laminar flow cooler has opened the automotive market to oil to water coolers. Oil to air coolers are lighter, cheaper and less bulky for comparable performance but Laminova coolers are resistant to crash damage, can be cleaned after a blow up and in installations where a plentiful air flow cannot be obtained are invaluable. The main components, the outer shell and the cores are aluminium extrusions. The cores have been machined to provide fins 0.2 mm (7 thou) thick and 3mm high and spaced 0.3mm (11 thou) apart through which the oil flows. Such restrictive finning would normally cause a huge pressure drop, but by introducing channels in the finning, the oil flow is kept laminar as opposed to turbulent as in other cooler designs and the pressure drop remains low. The water flows through extruded channels in the outer shell, removable plugs/restrictors control water pressure drop. 43mm core.
