Space erectable radiator system development

Abstract

The NASA Space Station's Space Erectable Radiator System features modular radiator panels with high-capacity tapered artery heat pipes bonded within their aluminum honeycomb structures. Simple, dry aluminum-to-aluminum thermal contact surfaces are used for the connections, thereby requiring no fluid joints; a uniformly distributed clamping force at the radiator panel-to-thermal transport loop interface heat exchange surface yields high thermal contact conductance as well as minimum area and weight for the requisite performance. The design has been optimized for weight and cost.
