Claims

[Scope of utility model registration request]

A pair of planar doughnut-shaped plates 3, each having an oil circulation hole 1 in the center, and a pair of cooling water communication holes 2, 2 spaced apart from each other, at least one of which is formed in an annular and shallow hat cross section;
3 are stacked on top of each other and liquid-tightly joined at their outer and inner edges to form a sealed flat cooling water channel 4, and the cooling water communication holes 2, 2 which are aligned with each other are A core 7 formed by stacking a plurality of elements 5 in a liquid-tight manner and forming oil flow passages 6 in the radial direction between the outer surfaces of each element 5, and the pair of cooling water at one end in the stacking direction. Cooling water inlet/outlet pipes 8, 8 protruding from the communication holes 2, 2 and a pair of the inlet/outlet pipes 8, 8 liquid-tightly penetrate through the core 7.
A casing 9 that fits around the outer periphery of the oil cooler.
