Abstract
An engine cooling system is provided, which comprises an engine body water jacket, a water pump, a radiator, a fan, a thermalstat, an expansion tank, a warm air machine cooler and a connection pipeline. The pipeline of the said components connects together to form a large circulating cooling passage, a small circulating cooling passage and a warm air system pipeline. The invention is characterized in that: a cut-off valve with temperature control function is positioned in the warm air system pipeline; when the engine starts and the temperature of the liquid coolant of engine is lower than the preset temperature, the cut-off valve is placed at the switch-off state. A cut-off valve with temperature control function can also be positioned in a small recycling loop; when the temperature is lower than the preset one, the cut-off valve is placed at switch-on state; when the temperature exceeds the preset one, the cut-off valve is placed at switch-off state. Because two cut-off valves with temperature control function are added, the liquid coolant does not flow through the warm air system before the temperature reaches the preset one, which reduces the heat loss and pre-heat time for the engine in this stage. Therefore, this invention can be best applied in winter or regions of harsh cold.
Description
Technical field
The present invention relates to the cooling system of vehicular engine, more specifically to the short circle of car engine cooling system and the rapid warming-up system of warm-air drier water cycle.
Background technique
What generally adopt on the motor car engine at present, is forced cyclic type water-cooled system.It utilizes water pump that cooling water is improved pressure, and it is circulated in engine cooling system.
" automobile construction " (the 2nd edition, the Guan Wenda of Jilin University chief editor, China Machine Press) discloses a kind of water-cooled and has been.All be cast with the water jacket that is interconnected in the cylinder head of water cooled engine and the cylinder block.Cooling water is under the effect of water pump, and the cooling jacket of the cylinder block of flowing through and cylinder head absorbs heat, then along the water pipe inflow radiator.Utilize the speed of automobile running and the strong pumping of fan, make air stream by forward direction after at a high speed by radiator, the heat of the high-temperature cooling water of the radiator of constantly will flowing through is dispersed into and goes in the atmosphere and cooling water temperature is descended.Cooled current are pressed into by water pump in the water jacket of motor once more through to the bottom of radiator, and a large amount of heats that produce when so circulation is just with engine operation are constantly taken away, thereby guarantee the motor proper functioning.Usually, the circulation route of cooling water has major cycle, promptly works as engine coolant temperature and is elevated to certain value, and thermostat main valve complete opening, auxiliary-valve are closed.Cooling liquid is lowered the temperature to flowing through the heat radiation of radiator ambient air through the thermostat inflow radiator, and last cooling liquid is returned water pump through radiator, carries out major cycle.When engine coolant temperature was low, the thermostat main valve was closed, auxiliary-valve is opened.Cooling liquid is after the water pump supercharging, body water jacket by motor, flow through around the water jacket wall again and from the water jacket wall heat absorption and heat up, upwards flow into the cylinder head water jacket then, after the heat absorption of cylinder head water jacket wall, flow through thermostat, short circle passage return engine body water jacket.On the short circle passage, also usually be parallel with the warm-air drier water circulation channel.
For making motor reduce heat loss when the low temperature, shorten warm-up period, under the big load condition of low speed, accelerate heat radiation, be provided with the device of regulating temperature in the cooling system, as thermostat, fan clutch and venetian blind etc.Thermostat is installed in the water intake of water pump or the water outlet of cylinder head.Its effect is the height according to engine cooling water temperature, changes the circulation route and the flow of cooling water automatically, so that motor is worked under only temperature all the time.Adopt waxtype thermostats on the automobile at present, its core is the wax heat responsive element more.One end of anti-push rod is fixed on the support, and the other end inserts in the center hole of rubber sleeve.Between rubber sleeve and metal shell refined paraffin wax is housed, utilize paraffin be heated the back by solid-state when becoming liquid state the character of volumetric expansion control.
But, in the moment of engine start, water pump entry into service (except the electronic water pump), open temperature because coolant temperature reaches thermostat this moment, and the cooling liquid radiator of not flowing through is only done short circle.But because short circle has the part cooling liquid warm-air drier (warm-air drier inside have a little radiator) of flowing through, can cause the loss of certain heat, increase the warm-up period of motor so undoubtedly, increase fuel consume.
Summary of the invention
The technical problem to be solved in the present invention is, in order to remedy the deficiency of available engine cooling system, and provides a kind of engine-cooling system of simple in structure, rapid warming-up.
The present invention solves the problems of the technologies described above to adopt following technological scheme: a kind of engine-cooling system mainly comprises engine block water jacket, water pump, radiator, fan, thermostat, expansion tank, warm-air drier radiator and connecting pipeline.When engine coolant is elevated to setting temperature, the thermostat main valve is opened, auxiliary-valve is closed, and the engine block water jacket is connected with thermostat, expansion tank, radiator, water pump pipeline and the engine block water jacket is connected the common major cycle cooling channel that forms with thermostat, short circle loop, warm-air drier radiator, water pump pipeline.When engine coolant temperature was lower than setting temperature, the thermostat main valve was closed, auxiliary-valve is opened, and engine block water jacket and thermostat, short circle loop, warm-air drier water tank, water pump pipeline are connected to form short circle cooling channel and warm air system pipeline; It is characterized in that: the shutoff valve of a function of temperature control is set in the warm air system pipeline, works as engine start, when engine coolant temperature was lower than setting temperature, this shutoff valve was in closed condition.
Can also the shutoff valve of a function of temperature control be set in the short circle loop, when being lower than setting temperature, this shutoff valve is in opening state, when being higher than setting temperature, this valve body that dams is in closed condition.Thereby guarantee the stable of major cycle cooling channel.
Above-mentioned shutoff valve mainly is made up of housing, fixed tray, slider disc and push rod, media cavity, spring; In the middle of the housing internal fixation places its fixed tray of importing and exporting two ends, spring, slider disc and push rod, the movable connection of media cavity order; When being lower than setting temperature, cooling liquid can flow in valve body; When coolant temperature reached setting temperature, the medium in the media cavity began to expand, and promotes slider disc and push rod, the interlock pressure spring, four spokes of slider disc was pressed in the water guide hole slot of fixed tray, had blocked flowing of cooling liquid.
Good effect of the present invention is, because it is opposite only to have increased by two working principles on the basis of existing cooling system, and temperature control shutoff valve simple in structure.Work as engine start, the cooling liquid warm air system of not flowing through has reduced the motor heat loss in this stage.Compare with original equal type in the design of warm air system pipeline, caliber also can increase.Whole project organization is simple, realizes easily.Having solved motor well needs the problem of long period warming-up when starting, be particluarly suitable for winter or colder area is used.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
