322 at least partly still can be arranged in the second vacuum chamber 333.
It can between at least any two in first vacuum chamber 331, vacuum sleeve 332 and the second vacuum chamber 333
To be interconnected, entire vacuum system can be vacuumized by a set of vacuum pump set.First vacuum chamber 331, vacuum
It can not also be connected between at least any two in casing 332 and the second vacuum chamber 333, pass through independent vacuum respectively
Unit is to corresponding partial vacuum.In first vacuum chamber 331, vacuum sleeve 332 and the second vacuum chamber 333 at least
It can be permanent vacuum environment inside any one, such as can will be set as permanent vacuum in vacuum sleeve 332, and by true
Empty unit pair the first vacuum chamber 331 and the second vacuum chamber 333 vacuumize, and arrangement above can be according to the actual application
It is selected and is designed, so that whole device is more succinct and compact, while reducing environment leakage heat.
It is carried out according to thermal controls apparatus provided by the utility model, including low-temperature receiver and heat-pipe apparatus, and by vacuum system
Insulated heat, wherein vacuum system includes the first vacuum chamber and vacuum sleeve, low-temperature receiver at least partly and condenser
Be at least partially disposed in the first vacuum chamber, vacuum sleeve is set in outside connecting tube, the inner wall of vacuum sleeve and connecting tube it is outer
There is gap between wall, vacuum environment is formed in the gap.Low-temperature receiver and condenser pass through with evaporator only by comparing thin
The remote transmission of low temperature cold, and flexible heat transfer, the vacuum sleeve being set in outside connecting tube are realized in long connecting tube connection
Scheme makes the heat-insulation vacuum system structure of entire thermal controls apparatus compact, without huge vacuum (-tight) housing and cold screen, substantially reduces outer
The environment leakage heat on boundary, entire thermal controls apparatus occupy little space, easily facilitate system flexible topology, can greatly expand Low Temperature Thermal
The application range for controlling device, makes it be used for wider application field.
Connecting tube can be internal and external casing structure, and fluid passage is formed in the inner tube of the internal and external casing structure, gas
Channel is formed between the outer tube and inner tube of the internal and external casing structure, with vacuum sleeve cooperate, sleeve structure from it is interior to
Outer to be followed successively by fluid passage, gas passage and vacuum environment, gas passage can play first layer to internal fluid passage
Insulated heat acts on, and is equivalent to one low temperature cold screen of setting outside fluid passage, the second layer thermal insulation of vacuum environment is coordinated to protect
Shield substantially reduces external environment to leakage heat inside fluid passage, ensures that the liquid working substance in condenser passes through fluid passage
Into evaporator.
Support element, the inner wall of support element and vacuum sleeve can be equipped between the inner wall of vacuum sleeve and the outer wall of connecting tube
And can be point contact between the outer wall of connecting tube can also be line contact, it on the one hand can improve vacuum sleeve and connection
The intensity of pipe is more convenient for bending, on the other hand the needs of adaptive system space layout can be avoided because of vacuum sleeve and connecting tube
Inside, which is in contact, causes environment leakage heat to increase, influence the problem of cryogenic liquid working flowing and long-distance sand transport.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
