Description
Technical field
The present invention relates to low energy detector thermal control technical field, in particular to the installation method of a kind of low-temperature deep heat pipe and
The assembly method of low energy detector.
Background technique
LE(low-energy) thermal control is a very important key technology, meaning for low energy X ray telescope
It is that thermal control guarantees low temperature required for LE detector SCD is worked normally, guarantees that heating avoids pollution problem after SCD enters the orbit, also
Guarantee the higher start-up temperature of LE detector cabinet electronics.SCD detector is functional within the scope of -80 DEG C ~ -45 DEG C of low temperature
And stablize, when temperature is more than -45 DEG C, dark current can be obviously increased, and detector energy, which is differentiated, to be deteriorated.SCD encapsulation is not complete
Closing, and SCD is more sensitive to pollutant, needs to guarantee that SCD is heated first after satellier injection by thermal control, avoids because low
Temperature and adsorb pollutant.LE detector lower case is due to taking heat loss through radiation processing, its temperature can be lower than after satellier injection
The minimum start-up temperature (- 40 DEG C) of electronics needs to guarantee that electronics start-up temperature is greater than -40 DEG C by thermal control.
Thermal control technological difficulties are: 1, orbit external thermal flux bad environments: firstly, LE detector is laid out the low temperature outside star
It is required that -80 DEG C ~ -45 DEG C external changes of heat flux are very sensitive, and the orbit altitude that HXMT satellite is chosen only seeing by 550km, load
The earth suffered by survey device is infrared and reflection of light Orbital heat flux is ill-conditioned, especially earth infrared heat flow.Currently, external similar
The high orbit of the most 7000km or more of X-ray astronomical satellite avoids the earth infrared and the influence of reflection of light Orbital heat flux, or adopts
The low temperature requirements of detector are realized with the active refrigeration to detector part thermoelectric cooling.It is only capable of at present in HXMT satellite using quilt
It is extremely difficult to the thermal control design of LE low temperature requirements in the case where dynamic heat loss through radiation thermal control measure.
2, multi-load one mounting arrangement: for HXMT Satellite Payloads, in order to guarantee that detector required precision will
HE, ME and LE detector that different temperatures requires are installed concentratedly on the same main supporting structure, maximum temperature index request
Difference reaches 70 DEG C.Thermal coupling is very strong between the load that multi-load one mounting arrangement requires different temperatures, and ties meeting
Under the premise of structure strength and stiffness, the provision for thermal insulation being able to achieve is limited, this meets temperature to HE, ME and LE three classes detector simultaneously
It is required that proposing bigger difficulty.
3, orbit external thermal flux variation is extremely complex: HXMT satellite there are mainly two types of operating mode, i.e., sky patrol mode and
Ocean weather station observation mode, both modes ratio shared by satellite their entire life are about respectively 50%.Satellite works at this two kinds
Attitudes vibration multiplicity under mode, the Orbital heat flux variation that load is subject to is considerably complicated, especially for ocean weather station observation mode, foundation
The observation time of observer target is several days, there is a situation where that the earth suffered by LE is infrared and reflection of light Orbital heat flux is very severe.
Meanwhile HXMT satellite uses the inclined plane of domestic satallite less, the in-orbit variation range in the angle β is further increased at 120 ° or more
The earth suffered by LE is infrared and the complex situations of reflection of light Orbital heat flux.All to thermal control design, more stringent requirements are proposed for these.
4, payload temperature stability requirement: LE detector is that a kind of state that approximation is exposed is in outside star,
Under the complicated Orbital heat flux state of HXMT satellite, if not taking effective thermal control measure, the temperature of LE detector is inevitably resulted in
Fluctuation is more than required temperature range.
5, detector and electronics heating requirements: LE detector needs to guarantee that its temperature is high by heating after satellier injection
In other part temperatures around, will not be adsorbed on LE detector in the volatilization of other component contamination objects.Due to LE detector sheet
Body has carried out good thermally conductive and heat dissipation thermal control measure, lower than the temperature of the other components of surrounding when temperature works normally.If
Needing to heat LE detector makes its temperature drift then need higher power consumption, while needing heating tape as close as possible to detector.LE
Detector lower case outer wall has heat loss through radiation coating at present, plays auxiliary heat dissipation function, mitigates and leaks heat to detector upper case.But
It is that LE detector lower case electronics is needed in -40 DEG C or more ability normal boot-strap work, so needing heating in advance.These are all
Carry out very big difficulty for LE thermal control adhesive coating, needs many-sided coordination that can just meet the requirements.
6, Cryo Heat Tube: it is main thermally conductive by heat pipe in current scheme, but Cryo Heat Tube (being lower than -60 DEG C) at present
Experience of not going up to the sky needs to solve the capacity of heat transmission of Cryo Heat Tube by tackling key problem and reliability is asked without reliable matured product
