1. A heat exchanger structure of an automatic transmission, comprising:

  • an automatic transmission;

    a first heat exchanger provided on an upstream side and a second heat exchanger provided on a downstream side, each capable of exchanging heat of oil ejected from said automatic transmission; and

    a thermo valve capable of supplying oil subject to heat exchange by at least one of said first heat exchanger and said second heat exchanger to said automatic transmission;

    wherein when a temperature of the oil is at most a predetermined value, said thermo valve supplies oil passed through said first heat exchanger to said automatic transmission and shuts off a flow of said oil from said second heat exchanger to said automatic transmission; and

    when a temperature of the oil exceeds the predetermined value, said thermo valve supplies oil passed through said first heat exchanger and said second heat exchanger to said automatic transmission.
