HEAT EXCHANGING DEVICE
First Claim
1. A heat exchanging device mounted on a vehicle provided with an engine, a fluid transmitting device including a lock-up mechanism, and an automatic transmission connected to the engine through the fluid transmitting device, comprising:
- a heat exchanger configured to perform heat exchange between first operating oil used in the engine and second operating oil used in the fluid transmitting device and the automatic transmission; and
a heat exchanging amount decreasing unit configured to, when a temperature of the second operating oil is lower than a predetermined temperature at which it is allowed to engage the lock-up mechanism, decrease a flow amount of at least one of the first and second operating oil flowing in the heat exchanger as compared to a case in which the temperature of the second operating oil is not lower than the predetermined temperature.
