Claims

[Scope of utility model registration request]

An oil communication hole 1 is formed in each center, and a pair of cooling water communication holes 2 are opened at a distance from each other, and a pair of plates 3, at least one of which is formed in a dish shape, is connected to its periphery and the oil. Communication hole 1
An element 4 having a flat, annular cooling water flow path 13 formed therein and a plurality of elements 4 are liquid-tightly joined to each other by the cooling water communication holes 2, 2 by liquid-tightly joining them at the hole edges. As a result, an oil flow passage 14 is formed between the outer surface of each element 4, 4, and between the outer peripheral edge and the oil communication hole 1, through which oil can flow radially.
A casing 6 which is formed into a cylindrical shape with one end closed and the other end open, into which the core 5 is fitted and whose open end is removably connected to the outer surface of the engine; Oil communication hole 1
a hollow bolt 8 that is inserted through the casing 6 and whose tip is removably screwed into the first oil hole 7 of the engine to fasten the casing 6 and allow oil to flow therein;
A pair of cooling water inlet/outlet ports 2 that communicate between each of the pair of cooling water communication holes 2 and the outside of the casing 6
1, an oil side partition portion 9 formed between the center position of the core 5 in the element stacking direction and the outer periphery of the hollow bolt 8 and preventing the oil from flowing in the axial direction of the bolt 8; A side opening 10 is provided on the outer periphery of the hollow bolt 8 on the axially outward side of the partition part 9, and a second oil hole 11 that opens on the outer surface of the engine, and a second oil hole 11 that is open to the outer surface of the engine, and between the outer circumferential edge of each element 4 and the inner circumferential edge of its oil communication hole 1 via the oil flow path of each of the cores 5 and above and below in the stacking direction with the partition portion 9 as a boundary. An oil cooler characterized in that the oil cooler is configured to flow in opposite directions in the radial direction.
