The invention relates to an intelligent control cooling system for a diesel engine. The system is composed of a high-temperature circulation loop and a low-temperature circulation loop. High-temperature circulation circuit components include high-temperature circuit electric control water pump, engine cooling water chamber, high-temperature circuit thermostat, high-temperature circuit water radiator, high-temperature circuit electric control valve; low-temperature circulation circuit components include low-temperature circuit electric control water pump, intercooler , Oil heat exchanger, low temperature circuit thermostat, low temperature circuit water radiator, low temperature circuit electric control valve. The opening of the electric control valve in the high and low temperature circuits is controlled in an open loop. The high and low temperature circuit electronically controls the speed of the water pump for closed-loop control. The invention can limit the working temperature of each part of the engine to the optimum range, prolong the service life of the heated parts, reduce the failure rate; reduce the heat transfer loss and power loss of the engine, improve its economy; shorten the heating time in winter; Early warning and fault diagnosis of cooling system.
Description
A kind of diesel engine intelligent control cooling system technical field The present invention relates to a kind of by automatically adjusting the temperature of diesel engine cooling medium, so that the working of each part of diesel engine As a cooling system whose temperature is limited within a certain range. Background technique Along with the substantial improvement of armored vehicle engine liter power, the high power of representative with main battle tank engine is high The thermal efficiency, thermal load and related reliability issues of compact diesel engines are becoming more and more prominent. high power density diesel engine The power per liter can reach 80-90kw / L, and the combustion process of diesel engine, thermal conversion efficiency, and working environment of parts and components all affect the cooling system. system put forward higher requirements. Due to the poor controllability and low efficiency of the cooling water pump and cooling fan, ...
