Description
Technical field
The present invention relates to technical field of vehicle, in particular to a kind of thermostat, engine-cooling system
With the vehicle with the engine-cooling system.
Background technology
Modern automobile industry is developed rapidly, and the recoverable amount of automobile is raised year by year, the exhaust emission for bringing therewith with
Problems of energy consumption is increasingly subject to people's attention, and the regulation of countries in the world energy-saving and emission-reduction is increasingly strict.
In order to further reduce the energy consumption of engine and discharge, finer engine is needed to design and develop.Engine
Cooling system is the important part of engine, dynamic property, fuel economy, reliability to engine,
Combustion efficiency suffers from important impact with exhaust emission.Thermostat is control cooling in engine-cooling system
The key components and parts of liquid flow path, thermostat must keep good state of the art, can otherwise have a strong impact on
The normal work of engine.If thermostat main valve was opened late, engine overheat will be caused, be reduced
The service life of engine, damages its Surrounding Parts；If thermostat main valve opens too early, may result in
Engine prewarming time lengthening so that engine temperature is too low, warm braw effect is poor, fuel economy is low, row
Put variation.
Most often waxtype thermostat used in existing thermostat, waxtype thermostat by temperature-sensing wax bag with
Thermostat shell is constituted, wherein, temperature-sensing wax incrustation is referred to as temperature sensor, inside and temperature-sensing wax is housed, by rubber
Sebific duct parcel push rod is placed in temperature-sensing wax.When chilling temperature is less than setting, the essence in thermostat temperature-sensitive body
, in solid-state, the passage that thermostat valve is cut out between engine and radiator under the action of the spring is cold for paraffin processed
But liquid Jing water pumps return engine, carries out partial circulating in engine.After coolant temperature reaches setting,
Paraffin starts thawing and gradually becomes liquid, and volume increases therewith and oppressing rubber tube shrinks which, in rubber tube
Push rod is acted on thrust upwards while contraction, push rod has downward propulsive thrust to open valve to valve
Open.At this moment systemic circulation coolant flows back to engine via thermostat valve and radiator, then Jing water pumps, carries out big
Circulation.
It was found by the inventors of the present invention that facility of the existing waxtype thermostat for assembling structure, by temperature sensor
Be mounted on thermostat lower house, temperature sensor is predominantly located in partial circulating, but still have fraction temperature sensor with
Affect the coolant directly contact of systemic circulation.When cold-starting automobile, due to environment temperature it is low, thermostat
Temperature-sensing wax bag can also sense the temperature of part systemic circulation coolant when partial circulating coolant temperature is sensed.Cause
Even if this partial circulating coolant temperature has reached the temperature of thermostat temperature-sensing wax bag thawing, but due to systemic circulation
Coolant temperature is low, causes thermostat open by design temperature in time.
