Space multi-target temperature consistency temperature-control method

Abstract

The invention provides a space multi-target temperature consistency temperature-control method. The space multi-target temperature consistency temperature-control method comprises the following steps:step one, implementing homeothermy of a single machine or an assembly on the same deck through embedded heat tubes, and meanwhile, adhering temperature measuring elements and electric heaters at positions corresponding to the heat tubes on the deck to control the temperature level of the heat tubes; step two, converting temperature difference control into original code difference control to implement temperature consistency control over single machines or assemblies on different decks; and step three, carrying out a space multi-target single machine or assembly temperature consistency controlstrategy. The problem that temperature consistency of the single machines or assemblies on the different decks is poor under the condition of severe outer heat flow is solved.

Description

technical field [0001] The invention relates to a temperature control method, in particular to a temperature control method for spatial multi-target temperature consistency. Background technique [0002] In the thermal control design of spacecraft, due to the electrical performance requirements of some stand-alone machines or components, it is necessary to control the temperature difference of similar stand-alone machines or components installed in different locations within a certain range, that is to say, such stand-alone machines must not only meet their own The temperature index requirement of {T|Tmin<T<Tmax}, and all single machines or components must also meet the temperature consistency requirement |ΔT|<C. [0003] Usually, if this type of single unit or component is installed on the same deck, the temperature consistency can be achieved by arranging heat pipes on its installation surface; , or the external heat flow of the deck changes differently, which of...

Problems solved by technology

[0003] Usually, if this type of single unit or component is installed on the same deck, the temperature consistency can be achieved by arranging heat pipes on its installation surface; , or the external heat flow of the deck changes differently, which often leads to certain difficulties in the temperature consistency requirements of the single machine or components. The common method is to raise all the single machines or components to a certain temperature to ensure temperature consistency. Not only does it consume a lot of power resources, but it also often makes the temperature of a single machine or component close to the upper limit of the index, and the temperature margin is small, and there is a certain risk
