Abstract

The invention discloses a phase change energy storage temperature controller for space. The temperature controller comprises a heat dispersion device, a heat storage device and a thermochromism paintlayer; the heat dispersion device consists of an evaporation section, a gas / liquid phase change cavity, support frames, a liquid sucking core, a condensation section, and gas / liquid phase mediums filled in the gas / liquid phase change cavity; the support frames are arranged in the gas / liquid phase change cavity in a lattice form; the heat storage device consists of a condensation section, gradual shrinkage layering ribs, a radiation section, and solid / liquid phase change storage mediums filled among gaps of the gradual shrinkage layering ribs; the widths of the gradual shrinkage layering ribs are reduced from top to bottom in the vertical direction; and the thermochromism paint layer is coated on the outer surface of the radiation section of the heat storage device. The heat dispersion device with the lattice support frames is excellent in temperature uniformity, and can eliminate local heat spots; and through the gradual shrinkage layering ribs, the heat exchange between the solid / liquid phase change storage mediums in the heat dispersion device and the heat storage device is strengthened, so that the energy storage is more efficient.

Description

technical field [0001] The invention relates to a temperature control device, in particular to a temperature control device for periodic high-power electronic devices on satellites. Background technique [0002] Thermal control technology is the key to ensure the normal operation of the spacecraft. With the increase in the number of satellites in various scientific and technological fields and the diversification of satellite work objectives, the working methods and working environment of satellites are becoming more and more complex, and more new heat dissipation problems have emerged. How to eliminate the local hot spots caused by short-term high-power operation of electronic devices on small satellites is one of the main problems to be solved urgently in thermal control technology in the aerospace field. At present, most satellites adopt a combination of active and passive thermal control modes. This method can complete the task of temperature control to a certain extent...
