High thermally conductive communications equipment panel module for communications satellite
Abstract
A new communications equipment panel module for satellite use has been developed to obtain a high thermal conductivity across the thickness in transversal direction of the panel. As the conventional communications equipment panel has a sandwich structure with aluminum alloy face sheets and a honeycomb core, the transversal thermal conductivity is relatively small mainly due to epoxy resin adhesive layers between the face sheet and the honeycomb core. Therefore, in order to dissipate high-heat flux towards space, a complicated thermal control system becomes necessary. The new panel module consists of a carbon-fiber-reinforced aluminum-alloy face sheet and a titanium-alloy core. A metallic bonding is used as the connection between the face sheet and core to enhance thermal conductivity of the panel is 1 × 10 -1 (W/K · mm) which is approx. 1000 times larger than that of the conventional panel.
