Claims

[Scope of Claim for Utility Model Registration] (1) Separate inlet pipes and outlet pipes are provided at the oil inlet and outlet, and the inlet pipe and outlet pipe are installed inside the radiator tank, and the inlet pipe and outlet pipe protrude from the side wall of the tank. In an oil cooler with a built-in radiator that is supported and fixed, the inlet pipe and auret are made of heat-resistant and oil-resistant rubber, which integrally has a pipe part and a seat part, and a metal pipe is inserted into the pipe part. An oil cooler with a built-in radiator that features a pipe welded to the oil inlet and outlet. (2) Inlet pipes and outlet pipes made of heat-resistant and oil-resistant rubber shall have an annular recess on the oil inlet/outlet side of the pipe portion into which the edge of the mounting hole provided in the radiator tank is fitted. An oil cooler with a built-in radiator according to claim 1 of the utility model registration claim, characterized in that: (3) The inlet pipe and outlet pipe made of heat-resistant and oil-resistant rubber are provided with an annular protrusion or an annular recess on the oil inlet/outlet side surface of the seat part,
An oil cooler with a built-in radiator according to claim 1 or 2, which is adapted to engage with an annular recess or an annular protrusion provided near an oil inlet/outlet. (4) Inlet pipes and outlet pipes made of heat-resistant and oil-resistant rubber are provided with an annular protrusion or an annular recess on the inner wall surface of the radiator tank in the seat part, and an annular protrusion or annular recess provided near the inner wall surface of the radiator tank. An oil cooler with a built-in radiator according to claim 1, claim 2, or claim 3, wherein the oil cooler is adapted to engage with a recess or an annular projection. (5) A utility model registration request characterized in that the pipe portions of the inlet pipe and outlet pipe made of heat-resistant and oil-resistant rubber have a tapered shape whose diameter gradually decreases from the seat side toward the tip.
