Efficient hybrid engine cooling system

Abstract

The invention provides an efficient hybrid engine cooling system. The efficient hybrid engine cooling system comprises a mechanical pump, a first one-way valve, a cylinder cover water jacket, a machine body water jacket, a supercharger cooling water channel, an EGR cooler, a thermolator, an oil cooler, a radiator, an electronic water pump and a second one-way valve; a water outlet of the mechanical pump communicates with an inlet of the first one-way valve through a pipeline, an outlet of the first one-way valve correspondingly communicates with a water inlet of the cylinder cover water jacketand a water inlet of the oil cooler through a pipeline, and a water outlet of the cylinder cover water jacket correspondingly communicates with a water inlet of the supercharger cooling water channeland a water inlet of the machine body water jacket through a pipeline. According to the efficient hybrid engine cooling system, the combination of the mechanical pump and the electronic water pump isadopted, the efficient hybrid engine cooling system still operates during machine halt, a machine body, a cylinder cover, a supercharger and the EGR cooler can be still effectively cooled and cannotbe rapidly damaged due to waste heat, and the operation reliability of an engine is kept.

Description

technical field [0001] The invention belongs to the technical field of engine cooling, and in particular relates to a high-efficiency hybrid engine cooling system. Background technique [0002] The cooling system is an important part of the engine. During the operation of the engine, the parts in contact with high-temperature gas or exhaust are strongly heated, and the cooling system is required to dissipate the excessive heat on these parts, otherwise various adverse consequences will occur, such as: deterioration of lubricating oil, damage of normal oil film; The heated parts expand and destroy the normal clearance of the kinematic pair; the thermodynamic performance of the parts decreases or even fails. In addition, it should not be cooled too much, otherwise it will cause poor combustion, increase emissions, and reduce fuel economy; the viscosity of the engine oil will increase, the friction loss of the moving pair will increase, and the engine will work rough, which wi...
