The BOYD Solution for Cryogenic Applications Temperature Control
Introduction to Cryogenic Space Applications
The ongoing development of space-based communications, sensors, and
experiments, as well as the evolution of spacecraft electronics, are
driving demand for tighter thermal control and more efficient heat
removal in low temperature microgravity environments.
NASA’s goal was to develop reliable Refrigerator/Freezer (R/F) modules for future Life and Biomedical Sciences spaceflight projects. To do so, they sought to identify, develop, and demonstrate the complicated key Refrigerator/Freezer technologies required for these advanced R/F modules.
Traditional thermal management solutions such as air or liquid cooling are not viable options in space applications. Instead, BOYD developed passive, two phase cooling solutions specifically designed for cryogenic applications for NASA to test during space shuttle missions.
The NASA Cryogenic Temperature Control Challenge
NASA was developing the Stirling Orbital Refrigerator/Freezer
(SOR/F) experiment to prove out technologies that would enable reliable
refrigeration during orbital projects. The subsystem candidates for the
SOR/F were to be tested on Space Shuttle Discovery (STS 60).
The Boyd Solution for Cryogenic Temperature Control
As there is little to no atmosphere
in space, dissipating heat into ambient air is not an option for
effective thermal management solutions. Radiation is the most reliable
cooling method in space, but internal components may not have access to
radiation surfaces.
Boyd has pioneered the development of cryogenic heat pipes and loop heat pipes designed for use in microgravity environments. Engineers from Boyd have demonstrated a wide range of heat pipe/fluid systems for cryogenic thermal management, including helium at -270℃ (3K), hydrogen at -250℃ (23K), neon at -240℃ (33K) and oxygen at -220℃ (53K).
Boyd, known then as Thermacore, recommended that NASA use cryogenic heat pipes to transport heat on the SOR/F experiment. Boyd designed and fabricated copper and acetone heat pipe assemblies for NASA to test on the Space Shuttle Discovery.
The Results of the Stirling Orbital Refrigerator/Freezer Test
The acetone working fluid enabled the heat pipes to function in
operating temperatures between -30°C (243K) and -60°C (213K) during
Discovery’s STS-60 mission. The SOR/F heat pipes were proven capable of
removing up to 10 W of power in the microgravity environment of space.

Boyd Loop Heat Pipes Set to Launch with NASA’s PACE Mission
NASA‘s PACE Mission is set to launch on Feb 8th with Boyd‘s loop heat pipes on board. LHPs are a method of passive heat transport that can span over 20 meters and can resist up to 9g acceleration forces. Loop heat pipes are also flexible up to millions of cycles, meaning it can withstand any vibrational flexing or actuations over the lifespan of the LHPs application.
