Pico/nano satellite heat flow infrared cage

Abstract

The invention relates to the technical field of temperature control of satellites, in particular to a pico / nano satellite heat flow infrared cage. The pico / nano satellite heat flow infrared cage comprises a satellite, baffles and infrared cage devices, wherein the satellite is of a cube structure; the infrared cage devices are of a rectangular sheet structure; one infrared cage device is arranged outside each side face of the satellite; the baffles are arranged between the side faces of the satellite and the infrared cage devices correspondingly; each infrared cage device is parallel to and concentric with the corresponding side face of the satellite; each side edge of each infrared cage device is L longer than the corresponding side face of the satellite, specifically, L is 100-200 mm; and the side edge of one end of each baffle is fixedly connected with the corresponding side edges of the infrared cage devices, and the side edge of the other end of each baffle points to the corresponding side edge of the satellite. The pico / nano satellite heat flow infrared cage meets the requirement for pico / nano satellite heat flow simulation, the heat flow uniformity of each surface is smaller than 5%, and heat flow simulation of the infrared cage for pico / nano satellite heat balance testing is achieved.

technical field [0001] The invention relates to the technical field of satellite temperature control, in particular to a Pina satellite heat flow infrared cage. Background technique [0002] With the development of microelectronics technology, especially the development of micro / nanotechnology represented by micro-electromechanical systems (MEMS) and micro-opto-electromechanical systems (MOEMS) in recent years, micro-satellites such as micro-satellites, nano-satellites, and pico-satellites Realization becomes possible. Pina satellites are satellites with a weight of less than 10kg. Due to the small size of Pina satellites, it is difficult to accurately simulate heat flow using traditional heat flow simulation methods and ideas.

Pina satellites are satellites with a weight of less than 10kg. Due to the small size of Pina satellites, it is difficult to accurately simulate heat flow using traditional heat flow simulation methods and ideas. Especially for some body-mounted battery chip satellites, it may be OK in the initial sample test. Consider using a heater for simulation, but at the positive stage, due to the body-mounted battery, the heating sheet cannot be pasted on the surface of the satellite, and the traditional method cannot accurately simulate its surface heat flow, resulting in insufficient verification of the thermal control design.
