Cooling device of engine

Abstract

The invention relates to the technical field of engines, and discloses a cooling device of an engine. The cooling device comprises a water pump, a cylinder block water jacket, a cylinder head water jacket, a temperature control module and a radiator. Coolant flowing out of the water pump flows from one side of the cylinder head water jacket to the other side of the cylinder head water jacket firstly, then flows through a first cavity of the cylinder block water jacket and finally flows back into the water pump, thereby ensuring that the cylinder head is fully cooled. In addition, when the temperature of the engine is high, the radiator is controlled by a low-temperature control valve to cool the hot coolant in the cooling cycle, so as to ensure that the cylinder head is effectively cooled;at the same time, when the temperature of the engine is even higher, the coolant flowing out of the water pump is controlled to flow through a second cavity of the cylinder block water jacket througha high-temperature control valve, so that the cylinder block is also effectively cooled, the cooling device of the engine can fully cool the cylinder block and the cylinder head of the engine, and further the temperature of the cylinder block and the cylinder head of the engine is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine cooling device. Background technique [0002] Automobile engines will generate a lot of heat during operation, if not properly cooled, it will easily lead to problems such as reduced strength of parts, increased wear and deterioration of engine oil, which will eventually affect the reliability and durability of the engine, and even reduce the service life of the engine . Therefore, it is necessary to take away the heat absorbed by the high-temperature parts when the engine is working in time, so that the engine can keep working within the normal temperature range. [0003] At present, the cooling device of the existing engine generally includes components such as a water pump, a thermostat control valve, a cylinder block water jacket of the engine, a cylinder head water jacket of the engine, and a radiator. When the thermostat control valve of the cooling device of the...

AI Technical Summary

Problems solved by technology

But, in the cooling device of existing engine, because coolant first flows through the cylinder block water jacket of engine and then flows into the cylinder head water jacket of engine, the temperature of the coolant that causes the cylinder head water jacket of passing through engine is too high, extremely unfavorable. It is beneficial to the cooling of the cylinder head of the engine, which is easy to cause problems such as low charging efficiency of the engine and combustion knocking
