Abstract: A three-way heat exchanger includes panel assemblies arranged in series. Each panel assembly includes a frame defining a heat transfer fluid channel and a vapor-permeable membrane positioned on the frame to define a desiccant channel separated from the heat transfer fluid channel. The three-way heat exchanger also includes clamping assemblies for exerting a clamping force on the panel assemblies. Each clamping assembly includes a tie rod extending through the frames of the panel assemblies and including opposite ends, retainers connected to the opposite ends of the tie rod, and a resilient element positioned between one of the retainers and one of the panel assemblies at one of the ends of the tie rod. The resilient element is deformable to accommodate size variations of the panel assemblies.

Abstract: A method and system is presented for producing a thermal radiator made from regolith, such as lunar regolith from the Moon's surface. Regolith generally comprises rough, irregular-shaped grains that collectively entrap pores and interstitial spaces, resulting in regolith's relatively low thermal conductivity. Solidified molten regolith, however, is a relatively homogeneous and continuous material having a much higher thermal conductivity. A method of fabricating a regolith thermal radiator may include forming a mold, melting regolith to form molten regolith, at least partially filling the mold with the molten regolith, and allowing the molten regolith to cool to a solid to form the thermal radiator. The mold may be formed in the Moon's surface by excavating lunar regolith where the thermal radiator is to be located. The molten regolith may then be cast in the mold.
