Cooling can also reduce engine infrared exposure intensity, shorten open-assembly time, be weaponry, especially using internal combustion engine as
The motor driven weaponry of power, such as various missile handling carriages, anti-enemy's infrared detection and strike are provided well under field environment
Camouflage condition.
3rd, the content of the invention
It is the cooling system structure diagram that fast cooling mechanism is designed with the basis of certain model engine-cooling system shown in Fig. 1.Figure
Middle A, B, C represent the partial enlarged drawing of the three kinds of different conditions occurred when thermostat 4 works respectively.It is cold when engine is operated
But the driving cooling water of water pump 3 for being is circulated between radiator 10 and body, and the driving air of fan 1 takes away the heat of radiator 10
Amount.The driving force of water pump and fan is all from bent axle 12, and power is transmitted by belt pulley 13.When engine is shut down, bent axle stops
Rotation stop is moved, and fan and water pump lose driving force, and cooling system is stopped.
When organism temperature is higher in engine operating, the expanded by heating of thermostat 4 (A in Fig. 1), main valve 19 is opened, pair
Valve 20 is closed, and cooling water flows out from cylinder head, is flowed through after radiator heat-dissipation and to be flowed down back engine body in water pump driving.Cooling
Water circulation road 4 → 11 → 9 → 10 → 8 → 3 → 7 → 6 → 5 → 4.This circulation is referred to as systemic circulation.
When organism temperature is relatively low in engine operating, thermostat 4 is by cold events (C in Fig. 1), and main valve 19 is closed, pair
Valve 20 is opened.Cooling water directly flows back to body without radiator heat-dissipation after partial circulating pipeline 2.Cooling water circulation road is through being
4→2→3→7→6→5→4.This circulation is referred to as partial circulating.
When organism temperature is in above-mentioned two temperature range in engine operating, the major and minor valve of thermostat is in half-open half
Off status, large and small circulation is all partly opened (B in Fig. 1).
From the above analysis：After engine stop operating, it is stopped therewith by bent shaft-driven water pump, fan.For
The cooling system of engine, as long as fan and pump working, then cooling system is in running order.Due between water pump and bent axle without just
When relation, using the driving relationship of belt pulley and belt, if set up between bent axle 12 and belt pulley 13 unilateral bearing (also known as
Freewheel clutch), just can the " stripping from the crankshaft connecting rod system of engine, valve actuating mechanism, lube system, fuel system by fan and water pump
From " come out.The resistance that cooling system work is driven under engine off condition is greatly reduced, so as to be driven with less external force
Dynamic fan and water pump rotation, makes cooling system in running order.
The present invention has following feature：
1st, fan and the driving of water pump external force drive automatic conversion with bent axle internal force
Freewheel clutch is set between bent axle 12 and belt pulley 13, it is constituted sees Fig. 2 with driving relationship.Freewheel clutch
Inner ring 2 is fixed on bent axle 12, and belt pulley 13 is provided with its outer ring 6, and external force interface 1 is located on belt pulley 13, both
It is fixed together.
When engine is operated, bent axle 12 is rotated clockwise, and ball 7, will under the frictional force effect of freewheel clutch inner ring 2
Spring 8 compresses, until ball is stuck between the Internal and external cycle of freewheel clutch, so that drive outer ring 6 and belt pulley 13 to rotate,
Freewheel clutch is bonding state.
When engine is shut down, bent axle 12 remains static, and now passes through belt pulley 13 rotationally clockwise of external force interface 1
And drive freewheel clutch outer ring 6 to turn clockwise.Because the rotating speed of freewheel clutch outer ring 6 has surmounted rotating speed (this of inner ring 2
When inner ring 2 because being remained static under the drag effect of engine), frictional force that ball 7 is produced in freewheel clutch inner ring 2 and
Spring force 8 makes ball return to released state under acting on, freewheel clutch is in released state.Realize the internal force of water pump and fan
The automatic conversion that driving drives with bent axle external force.
2nd, external force form and position are various
