Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to an oil cooling module and an engine assembly. Background Art

[0002] When the engine is working, the gas temperature in the cylinder can be as high as 1727 - 2527 °C. If not cooled in time, the temperature of the engine components will be too high. Especially the parts directly in contact with the high-temperature gas will be affected by thermal expansion and affect the normal clearance fit, resulting in the movement parts being blocked or even stuck. The engine cooling system can take away the heat generated by the engine combustion, so that the engine can maintain an appropriate working temperature under all working conditions. Similarly, the oil also needs an appropriate working temperature. At present, some high-power engines need an oil cooler to cool the oil due to relatively large thermal loads, so that the oil temperature is within a suitable temperature range.

[0003] The oil cooling module used in existing vehicles uses a pure mechanical structure at the connection of two oil cavities, that is, parts such as a plug, a spring, and a retaining ring. The elastic force of the spring itself keeps the oil flowing in the first oil cavity and the second oil cavity. Only when the oil pressure exceeds the limit value of the spring force, one of the oil cavities stops supplying oil; this cooling structure is relatively complex, with many components and a complex installation process; moreover, this cooling control mode is not precise enough, and the energy loss of the oil supply pump is large.
