Aluminium plate oil cooler

摘要

The aluminum plate oil cooler (2) includes a plurality of pairs of plates (5) that are secured along their perimeter to (10) define an oil flow path (30). The plates (5) include embossed regions (35) that are formed to provide inlet (37) and outlet ports (39) for the oil. Top (20) and bottom (25) reinforcement plates are positioned at the top (27) and bottom (29) of the plurality of pairs of plates (5). An internal center (40) is positioned between the plates (5) to increase the heat transfer area and turbulate the oil within the oil cooler (2). An external center (15) is positioned between each of the plurality of pairs (5) to increase the thermal transfer area on the coolant side of the oil cooler (2). The external center (15) covers the entire surface of the plates (5) and includes holes (21) formed to correspond with the embossed regions on the plates.
