Description

As thermal components make an important constituent of the spacecraft, constant development and optimization of such parts is needed. Within the H-PERTS project, HPS-RO focused on developing High Performance Thermal Straps. These parts represent thermal management solution, offering a combination of mechanical decoupling and thermal transfer.

Because the main goal of HPS-RO was to enhance conductivity of the thermal straps (with respect to the existing products), graphene sheets represented the focal point of the work. Such material has excellent thermal properties, but is not yet extensively used inside the EU. Through Development and Testing of the Graphene Sheets Thermal Straps, the following achievements were identified:

  • Improved thermal behavior of the straps by more than 10% compared to selected benchmark for a temperature range between 130K and 173K.
  • Significant mass reduction from 300 g (targeted mass) to 129 g.

The presentation will cover the main steps of the project, emphasizing the technical challenges in the development process encountered by HPS Romania.
