Temperature equalization control device and control method under the condition of unbalanced external heat flow

Abstract

The invention provides a temperature equalization control device and control method under the condition of unbalanced external heat flow, which is characterized in that it includes: a cabin body, a thin multi-layer heat insulation component, a thick multi-layer heat insulation component, a gas cylinder, a high emission rate thermal control coating, heater, and gas cylinder multi-layer insulation assembly; multiple gas cylinders are in the cabin, and multiple gas cylinders use one heater and are arranged in series to pass through the heater The size of the resistance value ensures that the power consumption of the cylinder heater in the area of ​​small external heat flow is large, and the power consumption of the cylinder heater in the area of ​​large external heat flow is small, so as to realize thermal compensation for multiple cylinders under different external heat flow environments. The invention can solve the problem of uniform temperature control of gas cylinders or large-volume devices under the condition of stable solar illumination conditions, tense power consumption of the whole star and tense electric heater circuits, and unbalanced external heat flow environment.

Description

technical field [0001] The present invention relates to the technical field of thermal control, in particular, to a temperature equalization control device and control method under unbalanced external heat flow conditions, and more specifically, to a control system based on multiple gas cylinders under unbalanced external heat flow conditions. Differentiated control methods. Background technique [0002] The traditional thermal design method of satellite gas cylinders is: After pasting heaters and temperature measuring thermistors on each gas cylinder, the entire gas cylinder is covered with multi-layer heat insulation components to reduce the heat exchange with the outside world, and then adopt The self-feedback closed-loop temperature control strategy controls its temperature independently, and controls the gas cylinder within a suitable temperature range. But now some satellites or aircraft are facing the problem of the number of heaters and energy shortage. The conventi...

Problems solved by technology

But now some satellites or aircraft are facing the problem of the number of heaters and energy shortage. The conventional thermal design scheme of individual temperature control for each gas cylinder cannot meet the overall requirements because it takes up more resources of the entire satellite.
