Abstract

The invention provides a thermal control film for a space. The thermal control film comprises a polyimide germanium-plated film body and a carburized polyimide film body, wherein the polyimide germanium-plated film body and the carburized polyimide film body are bonded with each other point to point locally through a polyimide double-sided pressure-sensitive adhesive. The thermal control film hasthe advantages that the polyimide double-sided pressure-sensitive adhesive is used for locally bonding the polyimide germanium-plated film body with the black carburized polyimide film body point to point, a microwave array antenna is completely coated, heat in the thermal control film is absorbed by the black carburized polyimide film body, and the high infrared emissivity of the polyimide germanium-plated film body is utilized to dissipate heat to the space. Meanwhile, the low solar absorptivity of the polyimide germanium-plated film body is utilized to reduce the high-temperature influenceof external heat flow of the space on the antenna. Since the weight of the thermal control film is much lower than that of spray paint of an antenna structure, the lightweight design of a satellite isfacilitated.

Description

technical field [0001] The invention relates to thermal control products for space vehicles, in particular to a novel thermal control film for space. Background technique [0002] The anti-high temperature measures of conventional satellite extravehicular antennas are mainly by spraying a coating with low solar absorption rate and high emissivity on the antenna structure to dissipate heat to the space. Since the microwave array antenna is mainly composed of a chip integrated array, the surface cannot be sprayed with a heat dissipation coating; in addition, the microwave array antenna needs to transmit or receive microwaves into the space, and the antenna itself generally has a large heat loss, so it is covered with multi-layer insulation The thermal component not only blocks the transmission and reception of antenna waves but also hinders the heat dissipation of the antenna, which is totally undesirable. Using heat pipes or adding heat expansion plates to transfer heat need...
