Embodiment
Contrast accompanying drawing below,, embodiment of the present utility model is described in further detail by description to embodiment.
A kind of quick constituent of motor comprises radiator 16, warm-air drier 15, cylinder body water jacket 13, cylinder cap water jacket 14, water pump 12 and thermostat, forms major cycle cooling channel, short circle cooling channel and warm air system pipeline; Thermostat is provided with two, is first thermostat 11 and second thermostat 10; This first thermostat 11 has two water intakes and two water outlets, is connected between the water intake of cylinder body water jacket water outlet 4 and radiator 16; This second thermostat 10 has two water intakes and a water outlet, is connected between the water outlet and water pump 12 of radiator 16; Warm-air drier 15 is arranged in parallel with radiator 16, is connected between two thermostats.
Have two water outlets on the cylinder body water jacket 13, a water outlet connects cylinder cap water jacket 14, and another water outlet connects a water intake of first thermostat 11, and cylinder body water jacket water outlet 4 connects another water intake of first thermostat 11, is not communicated with between this two water intake.
When two thermostats are not opened, the water intake that first thermostat 11 connects cylinder body water jacket 13 is a closed condition, another water intake is communicated with two water outlets of first thermostat 11, is respectively the first thermostat major cycle water outlet 5 and the first thermostat short circle water outlet 6 that is connected warm-air drier 15 that connect radiator 16; The water intake of the connection radiator 16 of second thermostat 10---the second thermostat major cycle water intake 8 is a closed condition, connect warm-air drier 15 water intake---the second thermostat short circle water intake 7 is communicated with its water outlet.When two thermostats were all opened, first thermostat 11 connects the water intake of cylinder body water jacket 13 to be opened, and is communicated with the first thermostat major cycle water outlet 5, and cooling liquid directly flows to radiator 16 from cylinder body water jacket 13 through first thermostat 11; The second thermostat major cycle water intake 8 is opened, and is communicated with water pump 12, and the cooling liquid that flows out from radiator 16 flows to cylinder body water jacket 13 cooled engines.
First thermostat 11 and second thermostat 10 are waxtype thermostat, are provided with in it to be solid-state paraffin under normal temperature, and this paraffin makes valve be in closed condition.First thermostat 11 and second thermostat 10 are set different predetermined temperatures, and the predetermined temperature of second thermostat 10 is lower than the predetermined temperature of first thermostat 11, reach separately predetermined temperature or more than, valve is also opened in the paraffin liquefaction in each thermostat.
As shown in Figure 1, flow to schematic representation for cooling liquid.Engine start, under water pump 12 effects, cooling liquid begins short circle, two thermostats are not all opened, cooling liquid flows into first thermostat 11 through cylinder cap water jacket 14 in the cylinder body water jacket 13, first thermostat 11 has two water outlets, cooling liquid one tunnel flows to warm-air drier 15 through the first thermostat major cycle water outlet 5, another road first thermostat short circle water outlet 6 flows to radiator 16, all flow to second thermostat 10 then, second thermostat 10 cuts out, and promptly the second thermostat major cycle water intake 8 is not opened, and is blocked herein from the cooling liquid that radiator 16 flows out, stop to flow, this moment, the second thermostat short circle water intake 7 was communicated with water pump 12, and the cooling liquid that flows out from warm-air drier 15 flows to water pump 12 through second thermostat 10, entered water pump 12 then and continued circulation.This is the short circle of this constituent, and forms warm air system.When the engine water temperature rise, at first paraffin liquefaction in second thermostat 10, second thermostat 10 is opened, the cooling liquid that originally was blocked in herein flows to cylinder body water jacket 13 through second thermostat 10 rapidly, can make engine cooling fast, this moment, first thermostat 11 was not also opened, and cooling liquid continues to flow to cylinder cap water jacket 14 in the cylinder body water jacket 13, flows back to radiator 16 through first thermostat 11 again; When engine water temperature continues to rise, paraffin liquefaction in first thermostat 11, first thermostat 11 is opened, first thermostat 11 connects the water intake of cylinder body water jacket 13 and opens, be communicated with the first thermostat major cycle water outlet 5, cooling liquid directly flows to radiator 16 from cylinder body water jacket 13 through first thermostat 11 without cylinder cap water jacket 14, can shorten the major cycle passage, accelerates the heat radiation cooling of motor.
Adopt technique scheme, in engine-cooling system, adopt two thermostats, and the predetermined temperature of setting second thermostat 10 is lower than the predetermined temperature of first thermostat 11, when water temperature rises, second thermostat 10 is opened, cooling liquid in the radiator 16 enters cylinder body water jacket 13 rapidly carries out, and realizes the quick cooling of motor, and this moment, the cooling system responsiveness was faster; And adopt two thermostats, and making between the cooling system temperature controlled region and strengthen, the water temperature of avoiding occurring motor is too high.
