Description
Technical field
The invention belongs to engine-cooling system technical field, a kind of constant device of automobile-used cooling and cooling system are particularly related to
System.
Background technique
According to investigations, the automobile engine source of failure in 50% or more the whole world is in cooling system.Engine is at work
A large amount of heat can be generated, after indicating oven temperature of engine, will lead to its efficiency is reduced, even Parts Breakdown.Automobile
The circulation that cooling system passes through pipeline and access progress liquid in engine.Heat can be absorbed when liquid flows through high-temperature engine
Amount, reduces the temperature of engine, provides temperature appropriate to guarantee that engine is in a suitable operating temperature.Liquid flows through
After engine, then heat exchanger (radiator) is flowed to, the heat in liquid is dispersed into air by heat exchanger.But automobile
After a period of use, often there is oil consumption increase, water temperature is easy higher, or even alarm " boiling ", and expansion tank is smudgy,
The problems such as not seeing liquid level, engine scuffing when serious, especially diesel-engine road vehicle.Leading to this failure cause is vehicle cooling system
System is enclosed cooling water heat exchange work system, and the hazardous substances such as iron rust, scale unavoidably generated in work can not be timely
It is discharged to outside system, blocks pipeline, cause cooling system heat dissipation bad, cause engine overheat, the thermal efficiency reduces, and oil consumption increases；
Coolant liquid main component is ethylene glycol, and high-temperature oxydation can generate acidic materials, PH is caused to reduce, and corrodes engine, transports for a long time
Row certainly will influence engine life and user's value.

Water flow is discharged in expansion tank, and when system pressure reaches setting value, relief valve is opened.
The shortcomings that prior art, is:
Corrosion: the iron rust generated in engine water jacket can not be discharged to outside system in cooling system circulation, block radiator
Pipeline, coolant liquid are unable to proper flow, and radiating efficiency reduces, and engine water temperature increases, even " boils ", oil consumption also will increase.
Scale: the calcium ions and magnesium ions in coolant liquid can slowly form scale after certain high temperature, block radiator pipeline and swollen
Swollen kettle relief valve, substantially reduces heat-sinking capability, and oil consumption increases.
Sour corrosion: to protect engine, coolant liquid pH value general control is 7.5~11, alkaline environment, but the prior art
Ethylene glycol high-temperature oxydation generates acidic materials and destroys coolant liquid pH value after a period of use, when pH value is lower than 7, Bian Huixun
Speed corrosion metal cylinder body, endangers engine life, engine scuffing when serious.
Parts Breakdown: on the inside of iron rust and scale wall built-up expansion tank, actual liquid level is not seen；Influence liquid level sensor essence
Degree or even Parts Breakdown.It is especially save the cost to the uncomprehending user of engine, fills tap water, is easier to occur above four
Class failure.
Bubble: the high temperature and pressure bubble during air-discharging enters expansion tank by radiator and engine, encounters low temperature
Explosion occurs for environment under low pressure, generates noise, also there is certain influence on part reliability.
