Description
Technical field
The present invention relates to spacecraft thermal control technical field more particularly to a kind of radiant type thermal control mechanisms.
Background technique
The thermal control mechanism of spacecraft is mainly used to the structure member for guaranteeing spacecraft and instrument and equipment under space environment
In a suitable temperature range, mechanism so that they can work normally.The thermal control mode being widely used on current spacecraft is big
Cause is divided into passive type and active two major classes.
Passive type thermal control is a kind of open loop type control, and relying primarily on rational deployment and selecting has appropriate thermophysical property
Material and thermal controls apparatus relatively simple for structure carry out tissue heat transfer process, this passive type thermal control mechanism is simple and easy, performance can
It leans on and long working life, but does not have the ability of automatic adjustment temperature generally.
Radiant type Active thermal control mechanism is to adjust heat loss through radiation ability and control temperature using driver drives action component
Degree.There is the radiation thermal control mechanism of application to have Thermal Control Shutter, thermal control turntable and flexible blade thermal control machine on spacecraft at present
Structure etc..Closed loop control is usually used in this active thermal control mechanism, usually by temperature sensing device, controller and execution machine
Structure three parts composition.When using active thermal control mechanism, the temperature information of controlled device can feed back controller, and preparatory
Setting value is compared, and then order executing agency movement as needed, realizes the automatic control of temperature, because it is able to achieve more sternly
Severe temperature guarantees, therefore applies relatively extensively on spacecraft, but this kind of active thermal control mechanism is more complicated, necessarily increases heat
The quality of control system, power consumption are bigger.
Summary of the invention
In order to solve the problems in the prior art, the present invention provides a kind of electrochromism thermal control mechanisms, every by controlling
A Thermal control units electrode realizes the thermal radiation property control of entire mechanism.The present invention is realized especially by following technical solution:
The upper surface of a kind of electrochromism thermal control mechanism, the thermal control mechanism is transparent surface thermal radiation, and lower surface is
Substrate；Several are closely arranged between upper and lower surface with electrochromic Thermal control units；Below each Thermal control units upper surface
There is first electrode layer, has the second electrode lay above lower surface, the first, second electrode layer polarity is opposite；Two electrode interlayers have one thoroughly
Bright hollow cylinder box, box is central axial to be equipped with rotatable shaft, and two cylinder of rotary shaft is respectively provided with an oppositely charged
Semicolumn.
As a further improvement of the present invention, the electrode layer is IR transparent films electrode layer.
As a further improvement of the present invention, thermally conductive between rotary shaft and substrate and two cylinders.
As a further improvement of the present invention, one of semicolumn is positively charged, and surface has high thermal emissivity, another
A semicolumn is negatively charged, and surface has low-heat emissivity.
As a further improvement of the present invention, by controlling the polarity of each Thermal control units electrode layer, so that two bands are opposite
The semicolumn of charge turns to target position according to field distribution, thus the thermal emissivity of control unit upper surface, and then control
The thermal emissivity of entire panel.
As a further improvement of the present invention, when the Thermal control units first electrode layer is positive, the second electrode lay is negative, then
Negatively charged semicolumn is in upper, positively charged semicolumn under, and the upper surface of Thermal control units has low-heat emissivity at this time.
As a further improvement of the present invention, when the Thermal control units first electrode layer is negative, the second electrode lay is positive, then
Positively charged semicolumn is upper, and electronegative semicolumn is under, and the upper surface of Thermal control units has high thermal emissivity at this time.
The beneficial effects of the present invention are: electrochromism thermal control mechanism structure of the invention is simple, power consumption is low, can pass through control
The thermal emissivity of each unit realizes the multiplicity control of entire mechanism surface heat radiation emissivity, and then flexible, effectively control is defended
The temperature field of star.
Detailed description of the invention
Fig. 1 is electrochromism thermal control mechanism part composition schematic diagram of the invention.
Specific embodiment
The present invention is further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, electrochromism thermal control mechanism upper surface of the invention is transparent surface thermal radiation 2, lower surface is
Substrate 1.Several are closely arranged between upper and lower surface with electrochromic Thermal control units.2 thermal control lists are illustrated only in Fig. 1
Member, the number of Thermal control units are arranged as the application of thermal control mechanism is practical, are not intended to limit patent right model of the invention
It encloses.
There is first electrode layer 3 below each Thermal control units upper surface, there is the second electrode lay 4 above lower surface, first, second
Electrode layer polarity is opposite.Two electrode interlayers have a clear hollow cylindrical body box 5, and box is central axial to be equipped with rotatable shaft, rotation
Two cylinder of shaft is respectively provided with the semicolumn 6 of an oppositely charged, and one end is positively charged, and surface has high thermal emissivity, surface
The other end is negatively charged, has low-heat emissivity.It is thermally conductive between rotary shaft and substrate and two cylinders.The electrode layer is infrared
Transparent membrane electrode layer.By controlling the polarity of each Thermal control units electrode layer, according to identical charges repel each other, the principle that there is a natural attraction between the sexes,
The semicolumn of two oppositely chargeds can be made to turn to target position according to field distribution, thus the heat of control unit upper surface
