5 and 16), a heat exchanger 17 provided separately from the heat exchanger 11 for performing heat exchange between the engine cooling water and the oil of the transmission 7 using the heat of the exhaust gas to generate the transmission oil. Heat directly without using cooling water. For example, the transmission oil is sent from the transmission 7 to the heat exchanger 11 via the pipe 8, sent from the heat exchanger 11 to the heat exchanger 17 via the pipe 10, and returned from the heat exchanger 17 to the transmission 7 via the pipe 9. I do. At this time, the oil heated by the heat exchanger 17 is returned to the friction engagement portion of the transmission 7. Regarding the operation, the oil is directly heated by the heat of the exhaust gas without passing through the engine cooling water, so that the transmission 7 can be warmed up quickly. Further, the oil heated by the heat of the exhaust gas is returned to the frictional engagement portion of the transmission 7 so that the effect of warming up the transmission can be achieved without heating all the oil in the oil pan of the lubricated machine. As a result, the transmission can be quickly warmed up. Further, since the transmission 7 is warmed up by the heat of the exhaust gas, the warming-up of the engine itself does not deteriorate in the process of warming up the transmission 7. In the above description, the transmission is taken as an example of the lubricated machine, but the lubricated machine is not limited to the transmission, and may be an engine.
Therefore, the oil is not limited to transmission oil, but may be engine oil.

る。According to the oil temperature control device of claims 1 to 4,
Since a heater, which is a heat source other than the engine, is disposed in the refrigerant circuit upstream of the heat exchanger, when the transmission is warmed up, the heater is turned on to heat the engine cooling water.
The temperature of the engine coolant flowing through the heater can be increased, and the temperature of the oil can be increased through heat exchange between the engine coolant and the oil in the heat exchanger. The machine can be warmed up. Since the heat source is different from that of the engine, the warm-up of the engine is not deteriorated in promoting the warm-up of the transmission. According to the oil temperature control device of the second aspect, since the heater heats the refrigerant by heat exchange between the exhaust gas and the refrigerant, the heat of the exhaust gas can be used for increasing the temperature of the engine cooling water, and energy can be saved. The engine cooling water can be heated. According to the oil temperature control device of the third aspect, the heater is EGR
Since it is composed of a cooler, EGR gas is cooled when cooling EGR gas.
The heat removed from the GR gas and discarded can be used to increase the temperature of the engine cooling water, and the engine cooling water flowing through the EGR cooler can be heated while saving energy. According to the oil temperature control device of the fourth aspect, since the heater is constituted by another heat exchanger for heating the refrigerant by exchanging heat between the exhaust gas and the refrigerant, the engine cooling flowing to the heat exchanger by the heat of the engine exhaust gas. The water can be heated, and energy for heating the engine cooling water can be saved.
