Thermal insulation connection device for space metal surfaces

Abstract

The invention discloses a heat-insulating connection device for metal surfaces in space. The upper metal surface [5] and the lower metal surface [7] are connected by bolts [9] and nuts [3]. The upper metal surface [5] and the lower metal surface [7] are connected by bolts [9] and nuts [3]. The joints between the bolts [9] between the lower metal surfaces [7] are partially padded with glass fiber reinforced plastic pads [4], and the rest of the area is filled with multi-layer heat insulation components [6]. The imide heat-insulating bushing [8], the nut [3] and the upper metal surface [5] are sheathed with a fiberglass washer [1] and a spring washer [2]. The invention solves the problem of heat isolation between space metal surfaces, and achieves beneficial effects such as low cost, high reliability, and good heat insulation effect.

Description

technical field [0001] The invention relates to a thermal insulation connection device used for space metal surfaces. Background technique [0002] The so-called heat insulation is to try to make the thermal resistance in a specific direction very large, so that the heat flow in this direction is as small as possible or limited to a certain value. In the thermal control system of space vehicles, it is often necessary to prevent high-temperature heat sources or fluctuating thermal environments from affecting the contacting instruments, equipment or components, especially between metal surfaces. To minimize the heat flow into these specific devices or areas, heat insulation measures are required, such as the connection between the solar wing connecting frame and the star body, and the connection surface between the extraterrestrial single machine and the star body heat insulation design. [0003] In a vacuum environment, there are only two heat transfer methods for spacecraft...
