An oil cooler is provided to keep the temperature of oil of an automatic transmission constant in an initial ignition by installing a hollow tube in the oil cooler lengthwise along a radiator tank such that refrigerant of a radiator flows on an outer surface of the hollow tube to transfer heat to oil of the automatic transmission. An oil cooler comprises a hollow tube and an entrance/exit boss. The hollow tube is formed lengthwise along a tank(30) of a radiator(1). The tank is coupled to an upper part of a header(20), which is coupled two ends of a plurality of tubes(10) having a fin(11), to form a passage for refrigerant. The entrance/exit boss communicates with two ends of the hollow tube and is coupled to an inlet(120) and an outlet(130) through which oil of an automatic transmission is introduced and discharged, respectively. |
