The main supporting structure of camera has several forms such as thin-walled cartridge type, integral frame-type and truss-like.Thin-walled cartridge type is mainly used in same
The middle-size and small-size space camera of axle, integral frame-type is generally metal integral casting forming.Truss structure succinctly reliable, assemble flexibly,
Specific stiffness is high, designability is strong, has excellent space performance, has become as one with fastest developing speed, most widely used at present
Space camera supporting construction pattern, is widely used in large-scale and the main force support structure of ultra-large type remote sensing camera, caliber high-precision
The fields such as the supporting construction of reflecting mirror, the extensible reflecting mirror support structure in space.
Space camera high stability truss rod generally uses the lightweights such as carbon fibre composite, near-zero linear expansion coefficient at present
New material, simultaneously in order to alleviate weight, be usually designed to open circles rod-type.This type of new material has common feature,
I.e. thermal conductivity is low, linear expansion coefficient is low.In conventional thermal control design, owing to truss rod material conducts heat rate is low, for ensureing its temperature water
Gentle temperature homogeneity, generally pastes substantial amounts of heater and temperature sensor at hollow truss rod outer surface, and this certainly will be to sky
The linear expansivity of heart truss rod can have a negative impact, and has obvious shortcoming.

Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.Fig. 1, Fig. 2 provide the suitable of the present invention
A kind of detailed description of the invention for the accurate thermal controls apparatus of the hollow truss rod of space camera high stability.
As it is shown in figure 1, be used for the accurate thermal controls apparatus of the hollow truss rod of space camera high stability, including: heater 1,
Soft joint 2, temperature sensor 3, control electronic box 4 and hollow truss rod 5.It is internal that heater 1 is built in hollow truss rod 5, not with sky
Heart truss rod 5 directly contacts, and is fixed with hollow truss rod 5 by the soft joint 2 installed on an internal surface.Soft joint 2 uses low heat conduction
Rate material, not only has heat insulating function, and has certain flexibility, it is possible to the deformation of isolation heater 1 is to hollow truss rod 5
Impact.Heater 1 can be divided into several thermals treatment zone, provides temperature strip by thermal-radiating mode for hollow truss rod 5
Part, heater 1 outer surface is high emissivity surface；Heater 1 is resistance-type heating rod or at heating object surface mount thin film
Heating plate.Temperature sensor 3 is fixed on hollow truss rod 5 outer surface, is used for detecting hollow truss rod 5 temperature.Control electronic box 4
By the temperature of collecting temperature sensor 3, control the switch of heater 1.Heater 1, temperature sensor 3 and control electronic box 4
Collectively form several closed-loop temperature control loops.
In one embodiment of the invention, hollow truss rod 5 a size of Ф 5mm*6mm, thickness is 8mm, and material is carbon
Fibrous composite.The size of heater 1 is Ф 3mm*6mm, and thickness is 1.2mm, and material is aluminium alloy 2A12.As in figure 2 it is shown,
Heater 1 is fixed on hollow truss rod 5 inner surface by 6 soft joints 2 being positioned at heater two ends, 3 soft joint 2 edges often held
