Heat, make part strongly heated.It if without appropriate cooling, cannot ensure the normal work of diesel-engine body, cool down
The function of system is to ensure that diesel-engine body works at normal temperatures, and the heat generated when diesel-engine body is worked distributes
It goes out, is cooled down.Cooling system influences the reliability of diesel-engine body work and consumes the size of power and entire power
Size, weight and the maintainability of device.
Since current marine diesel engine is mostly supercharged diesel engine, then charge air cooler is pressure charging system in supercharged diesel engine
Pith in supercharged diesel engine, can generate very high heat after air is compressed at high proportion, and the air of high-temperature is unfavorable
In tissue work by combustion, it is therefore desirable to high temperature air be cooled down before air is entered combustion chamber, the cooling effect is just
It is realized by charge air cooler, it follows that for supercharged diesel engine, usually needs radiator and charge air cooler simultaneously,
I.e. radiator and charge air cooler exist jointly respectively as two mutually independent devices.
Traditional supercharged diesel engine is generally non-integral design, and radiator and charge air cooler are arranged in the same of diesel-engine body
Side, therebetween in up and down or left and right arrangement, each other with supercharged diesel engine by pipeline connection, but in practical applications by
Big in radiator, charge air cooler occupied space, space is very big occupied by supercharged diesel engine, and compactedness is insufficient, and installation is difficult
Degree is big；Later stage by radiator, charge air cooler Integrated design on supercharged diesel engine, although compactedness has obtained certain promotion, by
In routinely using asymmetric structure, causing the pipeline that radiator and charge air cooler needs connect still more, installation difficulty is still big,
It is numerous in place of the turn of pipeline, water route, gas circuit on-way resistance is caused to increase, consumption power is big, increases system resistance, increases simultaneously
The risk that coolant has been added to leak, safety coefficient is relatively low, influences the operation stability and working efficiency of supercharged diesel engine.
