The flange is fixed on cooler support III9 and the interface is sealed by a sealing ring. The other end is sealed and connected to oil cooler support II12 by a sealing ring.

[0035] Oil line II13 is used to connect oil cooler support II12 and oil cooler support I15. One end of oil line II13 is connected to the flange in the form of a plug-in connection and sealed in the middle by a sealing ring. The flange is fixed on oil cooler support II12 and the interface is sealed by a sealing ring. The other end is sealed and connected to oil cooler support I15 by a sealing ring.

The other stream flows into the oil cooler support II12 and then into the oil cooler II20 to cool the engine oil. After cooling the engine oil, the high-temperature water flows from the oil cooler II20 into the oil cooler support III9. The two streams of high-temperature water merge at the oil cooler support III9 and circulate into the diesel engine's high-temperature water cooling system.
