An oil cooling system for a CNG vehicle is provided to prevent transmission oil or engine from being overheated under a specific travel condition, by improving cooling performance of automatic transmission oil and engine cooling performance. An oil cooling system for a CNG vehicle comprises a tank(50) for storing high pressure natural gas; a regulator(60) connected to the tank so as to reduce the pressure of high pressure fuel; a fuel intake pipe(70) connected to the regulator so as to supply natural gas fuel with reduced pressure to an engine(10); an automatic transmission(20) connected to the engine so as to automatically shift a shift gear in accordance with a vehicle operating condition; a heat exchanger(30) for cooling oil operating as working oil in the automatic transmission; a radiator(40) connected to the engine so as to cool the coolant circulating through the engine; and a coolant supply pipe(41) for supplying the coolant passed through the radiator and the heat exchanger to the engine. The fuel intake pipe has a part arranged to cover a periphery of the coolant supply pipe. |
