Rotary expansion type variable power space radiator

Abstract

The invention discloses a rotary expansion type variable power space radiator which comprises a heat pipe, heat dissipating fins, spherical protrusions, spherical grooves, a metal ring and a heat exchanger. The spherical protrusion is arranged at the tail end of the evaporation section of the heat pipe, the multiple heat dissipating fins are arranged in the heat insulating section and the condensation section of the heat pipe, the ends, close to the spherical protrusions, of the heat dissipating fins are provided with the spherical grooves, the metal ring is of a control structure, and the metal ring is provided with multiple spherical grooves. When the rotary expansion type variable power space radiator is in use, the spherical grooves in the metal ring are connected with the spherical protrusions at the tail end of the heat pipe, a space nuclear reactor is connected with the heat exchanger, the spherical protrusions on the heat exchanger are connected with the spherical grooves of the heat dissipating fins, waste heat generated by the space nuclear reactor is transferred to the condensation section through the heat pipe and finally radiated and transferred to the outer space by the heat radiating fins, the heat dissipating power is changed by changing the expansion angle of the heat radiating fins, and the variable power radiator can be used for various aerospace equipment power sources and systems

Description

technical field [0001] The invention relates to the technical field of design of space nuclear reactor power supply radiation radiators, in particular to a rotating and unfolding variable power space radiation radiator. Background technique [0002] With the development of space exploration, aerospace equipment systems have put forward a major demand for high-power space nuclear reactor power supply, and reliable and portable radiation radiators are key components of space nuclear reactor power supply. [0003] At present, most of the radiators used for space nuclear reactor power supply are fixed space radiation radiators, and a few space radiation radiators are directly expandable space radiation radiators. The above-mentioned fixed space radiation radiator is limited by the launch of the carrier, the heat dissipation area is small and the power is low, and it is difficult to meet the high-power space nuclear reactor power supply; although the directly expandable space rad...

AI Technical Summary

Problems solved by technology

The above-mentioned fixed space radiation radiator is limited by the launch of the carrier, the heat dissipation area is small and the power is low, and it is difficult to meet the high-power space nuclear reactor power supply; although the directly expandable space radiation radiator can be folded, which reduces the launch volume, but due to Its structure is fixed. When the space environment such as starlight time and temperature changes, the heat dissipation power cannot be changed according to the environment, which in turn affects the power output of the space nuclear reactor power supply.

[0004] In addition, the current folded and directly unfolded radiant radiator is still in the stage of conceptual demonstration, and the structure and principle of the actual unfolding device have not been proposed.
