Based on previous development, the objective is to develop a mass-efficient heat accumulators using PCM (Phase Change Material) to avoid overheating of specific power demanding electronic boxes. More specifically, the goal is to increase the TRL Level to 6-7 by performing more qualification tests, which will provide a higher reliability and confidence in the PCM technology.

 

A PCM provides a temporary cooling capability of electronics boxes when overheating/absence of effective cooling leads to over-temperature for any type of spacecraft or launcher. The proposed technology saves mass vs traditional heat sinks for applications where high power dissipation occur for a short period of time.

The activity shall focus on the following points: ?

 

• Radiation resistance of organic PCM?s: samples and whole PCM box, needing a large quantity of PCM to be irradiated under p and gamma

• Perform fatigue testing during thermal cycles (including under vacuum). ?

• Reduce the error on latent heat measurement (compare DSC ? Time history).

• Development of MGSE for filling, un-filling and certification of filling rate.

• Measurement of burst pressure and safety against over pressure.

• Explore feasibility in using additive Manufacturing.

• Establish manufacturing procedures and processes in order to provide a controlled and reliable product.

 

A product specification shall be supplied by a European Prime to insure full applicability. Engineering and qualification models shall be manufactured in order to perform pre/post irradiation tests, burst tests, in-process tests, filling/unfilling tests and ageing test.
