Cooling system and method of engine

一种发动机的冷却系统和方法

Abstract

一种内燃机的冷却系统和方法,尤其是船用柴油机的冷却系统和方法。采用双热交换器,分别布置在高温支路和低温支路中,内部冷却液经发动机本体加热后分成第一内部冷却液支路、第二内部冷却液支路:所述第一内部冷却液支路包括第一节温器、副热交换器、高温级中冷器;所述第二内部冷却液支路包括第二节温器、主热交换器、低温级中冷器;通过第一内部冷却液支路和第二内部冷却液支路的内部冷却液汇合后回到发动机本体形成闭合冷却回路。满足了整机的尺寸要求、降低了冷却系统成本、提高了冷却系统的可靠性,改善了发动机的燃烧情况。
The invention provides a cooling system and method of an internal combustion engine, in particular to a cooling system and method of a marine diesel engine. Double heat exchangers are adopted and arranged in a high temperature branch and a low temperature branch correspondingly, internal cooling liquid are divided into a first internal cooling liquid branch and a second internal cooling liquid branch after being heated by an engine body, and the first internal cooling liquid branch comprises a first thermostat, the vice heat exchanger and a high temperature stage intercooler; the second internal cooling liquid branch comprises a second thermostat, the main heat exchanger and a lower temperature stage intercooler; and internal cooling liquid passing through the first internal cooling liquid branch and the second internal cooling liquid branch are converged and then returns to the engine body to form a closed cooling loop. According to the cooling system, size requirement of a whole engine is met, cooling system cost is lowered, the reliability of the cooling system is improved, and the combustion condition of the engine is improved.
