“…In 1997, a suite of cryogenic experiments flew aboard the Space Shuttle mission STS-94 that included the Oxygen Flexible Diode (OFD) which contained a cryogenic oxygen heat pipe and the highest capacity methane heat pipe ever flown at the time [2]. Bugby described the testing of four Cryogenic Loop Heat Pipes (CLHPs) with various working fluids that included ethane, neon, and nitrogen [3]. The ethane LHP once strongly considered for the SIM Lite program, transported a 40 W heat load at 200K across 3 meters span with a conductance better than 10 W/K.…”

The objective of this work is to design a passive thermal switch with Kirigami-inspired architected materials composed of bilayer hinges and to analyze thermomechanical and thermal performance at the ON/OFF states based on a composition of materials and geometry of metamaterials. Analytical models are constructed to determine the thermal deformation and heat transport of the metamaterial, followed by finite element-based simulations. A two-step design approach À i) selection of multi-materials and ii) geometric modification of mesostructures provides a robust method for the design of a passive thermal switch with Kirigami-inspired metamaterials. The mesostructures designed have potential as a passive thermal switch enabling to engineer a large thermal deformation, a small thermal resistance, and a sizable thermal switch ratio. With a systematic approach, this work demonstrates that Kirigami structures with multi-materials can be potentially used for a tool of thermal transport.
