Engine oil cooler and control method thereof

Abstract

The embodiment of the invention discloses an engine oil cooler and a control method thereof, and relates to the technical field of engine cooling. The engine oil cooler can filter cooling liquid and keep the cooling liquid clean, the circulating bypass is arranged, and when the filtering device is blocked, the cooling liquid with enough flow can continue to cool the cooler. The engine oil cooler comprises a heat exchange part, a filtering device and a circulation bypass, wherein a cooling liquid inlet pipeline and a cooling liquid outlet pipeline are arranged on the heat exchange part; the filtering device is arranged in the cooling liquid inlet pipeline and is used for filtering impurities in the cooling liquid; the circulation bypass and the filtering device are arranged in parallel, a bypass valve is arranged on the circulation bypass, a pressure action part is arranged in the bypass valve, and when the pressure difference between the two sides of the filtering device is larger than a preset value, the bypass valve is opened, and cooling liquid enters the heat exchange part through the circulation bypass. The embodiment of the invention provides an engine oil cooler which is used for cooling engine oil.

Description

technical field [0001] The embodiments of the present application relate to the technical field of engine cooling, and in particular, to an oil cooler and a control method thereof. Background technique [0002] The engine will generate a lot of heat when it is working. If the heat is not cooled in time, the temperature of the components in the engine will rise, which may cause deformation or even damage to the components, affecting the normal operation of the engine. [0003] The high-speed running part of the engine is provided with organic oil. The oil is used as a lubricating medium and also plays a role in cooling. The engine is also generally equipped with an organic oil cooler to cool the engine oil and ensure that the engine oil temperature is maintained at Within a reasonable range, avoid oil deterioration caused by excessively high oil, and effectively prolong the service life of the oil. [0004] Since the high-speed moving pair in the engine will generate metal p...

Problems solved by technology

However, when replacing or adding coolant, it is also possible that impurities will enter the coolant; or the pipeline of the coolant will decompose and impurities will enter the coolant after long-term use, and the coolant containing impurities will affect the cooler during operation. The heat exchange part of the engine will cause erosion. Long-term erosion will cause the coolant side and the oil side of the cooler to penetrate, resulting in oil-water mixing and damage to the engine.
