PIPE CONNECTING STRUCTURE FOR OIL COOLER

摘要

A pipe connecting structure for an oil cooler is provided to assemble a pipe simply in a one-touch manner so as to reduce the number of assembly processes, and to prevent oil leakage securely by using a sealing ring. A pipe connecting structure for an oil cooler includes an oil cooler main body(20), a flare connector(24), and a pipe(26). The oil cooler main body is formed of a dual pipe and installed in a radiator tank. The flare connector is coupled to an outer wall of the oil cooler main body and fixed to a radiator tank wall by nuts(22). The pipe is fixed to the flare connector. The flare connector includes a flange part(24a) formed at a lower end thereof and contacted by the radiator tank wall. The radiator tank wall and the nut are sequentially coupled to a cylindrical part formed on the flange to fix the oil cooler main body. A first stopper ring to which a sealing ring is fitted is formed at an inner lower part of the flare connector.
