Description
Technical field
The present invention relates to a kind of radiators, more particularly to a kind of the integrated of hypergravity acceleration high speed geotechnical centrifuge
Radiator.
Background technology
High acceleration, high speed geotechnical centrifuge are the geology such as research ground develops, geological structure develops, the reduction of geology disaster
The essential device of evolution process reproduction test.With being continuously increased for acceleration g, the heat dissipation of geotechnical centrifuge itself is asked
Topic becomes a problem, because the rotating speed of centrifuge and linear velocity are higher, the heat that pivoted arm, hanging basket and windage generate is got over
Greatly.When below acceleration 500g, the cooling of cold wind unit or natural wind circulation cooling generally may be used.But when acceleration
Degree increases to after 1000g or more or even 1500g or more, and quantity of heat production can reach 10MW in the centrifugation cabin of 11 meters of diameter, be equivalent to
The heat exchange amount of 50000 square metres of large-size air conditioning unit, so huge heat exchange needs huge air quantity, and wind-force crosses conference shadow
The vibration of pivoted arm is rung, therefore traditional cold front heavy rain cannot meet the needs of high acceleration centrifuge heat dissipation, and temperature control solves
Bad, all instrument centrifuged in cabin will appear problem, general to require centrifugation cabin temperature control at 45 DEG C or less.It is general to adopt more
With the method cooling being combined with centrifugation wall surrounding cold water cooling；But when the load of centrifuge further increases, centrifugal chamber
Interior quantity of heat production can further increase, and at this time cold front heavy rain joint cold water cooling is also unable to reach the requirement of heat dissipation.To understand
Certainly this problem, most efficient method are vacuumized to centrifugal chamber, reduce the density of air to reduce the friction of pivoted arm and air
Heat, but other problem can be caused after vacuumizing, when due under vacuum state air molecule it is thin, heat-transfer capability is also big
Width declines, and under vacuum state air can not convection current, therefore, the raised heat of pivoted arm temperature caused by pivoted arm and windage without
Method is effectively passed.Another problem is the bearing meeting oil leak of centrifuge under high vacuum, and the sealing of centrifugation cabin surrounding all becomes
Must be difficult, therefore vacuum degree cannot be too high.Therefore needing to find effective method makes pivoted arm temperature be reduced within the scope of room temperature.

Here is the Principles of Regulation and temprature control method of the present invention：
a）After the startup of hypergravity acceleration supercentrifuge, since centrifuge pivoted arm 14 and one are equipped with 15 He of test specimen hanging basket
Friction generates heat with air generation for another hanging basket 15 equipped with balance weight, and the indoor temperature in centrifuge cabin is made constantly to increase,
It must be turned on cold front heavy rain system at this time.The cold wind of cold front heavy rain system is from the first cold wind import pipe 27 and the second cold wind import pipe
22 enter, and are discharged from the first cold wind outlet 6 and the second cold wind outlet 13 after exchanging heat with the indoor hot-air in cabin.
b）When the cold wind of quenching system is not enough to control temperature rise, start cold water cooling system, cold water is from cold
The cold water inlet 4 of the upper end of water leg enters, the flowing in cooling jacket 1 by spiral runner, under cooling jacket 1
The cooling water outlet pipe 18 at end flows out, and the temperature for centrifuging bulkhead 7 is cooled down, to centrifuge the air cooling in cabin.
c）When quenching system and chilled water system are unable to control temperature rise, stop quenching system, closes centrifugation cabin
All exits and entrances valves, start vacuum system, by centrifuge cabin in air taken away from true hole exhaust pipe 11.The height of vacuum degree
It is determined by centrifuging the temperature in cabin, until the temperature in centrifugation cabin no longer rises.
d）Extremely difficult due to centrifuging the heat transfer in cabin under vacuum state, the heat on centrifuge pivoted arm can not transmit
It goes out, water-vapor mixer can be opened at this time, by the way that the gas-vapor mix of molecule is passed through multiple nozzles sprays to centrifugation
On machine pivoted arm 14, the heat on centrifuge pivoted arm 14 is absorbed by the evaporation of steam under vacuum conditions, to reach control from
The rising of 14 temperature of scheming pivoted arm.
