Abstract

The invention discloses an engine cooling system. The engine cooling system comprises an expansion kettle, a high-temperature circulation system and a low-temperature circulation system, wherein the high-temperature circulation system comprises a mechanical water pump, a thermostat, an engine oil cooler, a gearbox oil cooler and a cylinder body water jacket; a water outlet of the mechanical water pump is provided with a first branch, a second branch and a third branch, and the third branch communicates with a liquid inlet of the gearbox oil cooler; the thermostat comprises an inlet channel, a liquid outlet of the gearbox oil cooler communicates with the inlet channel, and a liquid outlet of the thermostat communicates with a water inlet of the mechanical water pump; and the low-temperature circulation system comprises an electronic water pump and a low-temperature radiator, a closed loop is formed by the electronic water pump and the low-temperature radiator, and an air inlet of the expansion kettle communicates with the closed loop through a first degassing pipeline. According to the engine cooling system, the low-temperature circulating system can be used for degassing under various working conditions, and meanwhile, precise control over the temperature of a high-temperature circulating loop is realized.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine cooling system. Background technique [0002] The engine cooling system is one of the important systems to ensure the normal and stable operation of the engine. Its main function is to ensure that the engine has the most suitable working temperature under various working conditions. The cooling system has a great influence on the power, economy and reliability of the engine. big impact. The temperature of the cooling system is mainly controlled by the thermostat, which automatically changes the circulation route and flow rate of the cooling water according to the temperature of the engine water, so that the engine always works at the most suitable temperature. [0003] In the existing engine cooling system, the high-temperature circulation system is generally degassed through two pipelines, the low-temperature circulation system is degassed through one pipeline, and th...
