MULTI-PLATE OIL COOLER
Document Type and Number:
WIPO Patent Application WO/2014/073471
Kind Code:
A1
Abstract:
Provided is an oil cooler (10) in which first and second core plates (5, 6) are stacked in an alternating manner and oil flow paths (7) and coolant flow paths (8) are configured in an alternating manner between the core plates. The peripheral edge sections (5a, 6a) of the core plates (5, 6) form a tapered shape that spreads outward. Inner peripheral boss sections (30) and outer peripheral boss sections (32) that protrude upward or downward are provided adjacent to each other around a central oil communication hole (17) so as to form a concentric shape. The surfaces of the inner peripheral boss sections (30) are joined together at an intermediate height position of the oil flow paths (7) and the surfaces of the outer peripheral boss sections (32) are joined together at an intermediate height position of the coolant flow paths (8). By providing the boss sections (30, 32) in a continuous concentric shape, a central oil passage (18) is isolated from the oil flow paths (7) and the coolant flow paths (8), and it is possible to seal each of the oil flow paths (7) and the coolant flow paths (8).
