Technical field

The present invention relates to AEROSPACE APPLICATION technical fields, and in particular to high power density single machine fluid circuit radiation on a kind of star Device.

Background technique

The purpose of satellite thermal control technology is control inside satellite and external environment heat exchanging process, realizes that on-board equipment heat is flat Weighing apparatus temperature is in claimed range.Thermal control technology is the important component of space technology, and design level and quality influence Working condition, service life and the reliability of entire satellite.With the continuous development of space technology, the application range of satellite gradually expands Greatly, on star payload because function difference it is multifarious, therefore satellite thermal control technology is constantly faced with new challenges.

Wherein, biggish heat consumption will be generated when high power density single machine is operated at full capacity on star, thermal control design necessarily encounters The quick transmitting of big heat and dissipation problem.For such problem, existing method mainly has adopting heat pipes for heat transfer system, monophasic fluid Loop cooling system and two-phase fluid loop cooling system.Wherein, Fluid for Single-phase Fluid Loop System cooling system it is strong with its heat transfer property, can It is concerned by the advantages that property height and simple process.Fluid for Single-phase Fluid Loop System cooling system is by Fluid for Single-phase Fluid Loop System and radiator group At the former can realize the quick transmitting of big heat, and the latter then realizes the efficient heat extraction to space environment.And the design of radiator exists While considering single machine radiating requirements, also to reduce its volume and weight as far as possible, reduce launch cost.Currently, radiator The mainstream shape of design has cylinder-shaped radiator, the single side wing-tubular type radiator, the flat radiator of rectangular conduit and pipeline-rib Chip radiator.

Cylinder-shaped radiator is mainly used in the temperature control system of international space station and Large Spacecraft.The system is to navigate The cylindrical wall of its device is coiled in the outer surface of radiator, passes through fluid circuit and spoke as radiator, fluid circuit pipeline The direct thermal coupling of emitter reduces thermal resistance, realizes the efficient heat transfer to spacecraft and accurate temperature control.The design of this radiator is suitable The larger and relatively regular shape spacecraft for body surface area.

The single side wing-tubular type radiator is mainly used in the thermal control design of space shuttle, using the covering of space shuttle as Radiating surface, the flow duct of cooling fluid are directly welded in space shuttle covering inner surface.This structure process is simple, weight It is small, high reliablity.But there is also certain disadvantages for the single side wing-tubular type radiator: radiator is thermally conductive with space shuttle covering It will affect the heat-sinking capability of system;And the transverse direction of covering is thermally conductive poor, causes radiator surface there are biggish temperature gradient, Influence the radiating efficiency of radiator.

The flat radiator of rectangular conduit is made of many flat rectangular conduits, and the top and bottom of conduit or one side are made For radiative heat rejection face.Heat transfer efficiency between the radiator and fluid is very high, and the temperature uniformity of plate radiating surface is preferable, can To realize the efficient heat extraction to space environment.Meanwhile except the flat radiator of rectangular conduit is independently of the structure of spacecraft, because This its occupied space is larger, and weight demands improve.And the conduit in the radiator is more, and runner design is complicated, process implementing Difficulty increases, and reliability reduces.

Pipeline-rib-type radiator is made of multiple pipelines-fin unit, the top and bottom of pipeline and fin in each unit As radiative heat rejection face.The fin arrangement of the radiator can with flexible design, can also be used multi-pipeline reinforce fluid and fin it Between heat exchange.Meanwhile that there is also fin temperature uniformities is poor, weight demands are high, runner design is complicated etc. lacks for this radiator It falls into.

With the rapid development of space technology in recent years, the functional requirement of spacecraft is continuously improved, satellite equipment equipment Highly integrated, high power density single machine heat consumption gradually increases.And above-mentioned several existing space radiators can not expire well The thermal control requirement of high power density single machine on sufficient star.Therefore, there is an urgent need to a kind of radiating efficiency height, simple process, reliable now Property the high, radiator that occupies little space solve heat dissipation problem when high power density single machine is operated at full capacity for a long time on star.
