Thermal Pyrolytic Graphite Enhanced Components, Phase I

Completed Technology Project

Project Description

Thermal Pyrolytic Graphite Enhanced Components, Phase I
Peregrine's innovation will reduce the required input power, increase a coolers systems margin for a giving cooling load and reduce vibration accordingly for Reverse-Brayton Cycle Cryocoolers. Our innovation will enhance the thermal conductivities of structures associated with the cryocooler, enable much more efficient heat removal and thereby produce a much more efficient system. Effectively we will be increasing the thermal conductivities of the structures associated with the cryocoolers by embedding Thermal Pyrolytic Graphite within a matrix of material to produce a thermal conductivity 3 times higher than current available materials. At the end of Phase I Peregrine will have demonstrated the feasibility of our innovation and laid out a detailed design and test plan for Phase II. At the end of Phase II Peregrine will have produced a flight like product tested for future satellite applications. Phase II will also incorporate characterization of the material and engineering guidelines. As cryocooler technologies attempt to cool components down around the 4oK level waste heat and the management thereof becomes critical to the performance of the cryocooler. Thermal conductivity structures that can eliminate thermal loads more effectively will lead to a more efficient and better performing cryocooler. More »
