[0002] The oil heat exchanger is an important component in the diesel engine's running lubrication system, and it can also heat the oil when needed. The oil heat exchanger is widely used in diesel-powered vehicles at home and abroad for cooling.

[0003] The Chinese authorized announcement number is CN212583807U, a diesel engine heat exchanger with adjustable heat dissipation area. When the user opens the valve, the fluid can enter the winding tube from the water inlet pipe through the diverter pipe, thereby increasing the heat dissipation area, improving the heat dissipation efficiency, and controlling the temperature inside the diesel engine. At the same time, the design of the winding tube makes the maximum use of the internal space, and can also make the heat dissipation of the fluid in the winding tube more uniform, so that the heat dissipation area is increased without destroying the original heat dissipation effect, while increasing the efficiency of use, greatly increasing the practicality, and facilitating the use of users.
