<P>PROBLEM TO BE SOLVED: To provide a heat exchanger structure of an automatic transmission capable of stabilizing the temperature of an oil. <P>SOLUTION: This heat exchanger structure 1 of the automatic transmission can cool the automatic transmission 10 and the oil discharged from the automatic transmission 10 and comprises a first heat exchanger 40 installed on the upstream side and a second heat exchanger 50 installed on the downstream side and a thermo valve 30 capable of supplying the oil heat-exchanged in at least one of the first and second heat exchangers 40 and 50 to the automatic transmission 50. When the temperature of the oil is relatively low, the thermo valve 30 supplies the oil passed through the heat exchanger 40 to the automatic transmission 10 and cuts off the flow of the oil from the second heat exchanger 50 to the automatic transmission 10. When the temperature of the oil is relatively high, the thermo valve 30 supplies the oil passed through the first and second heat exchangers 40 and 50 to the automatic transmission 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
