A substrate formed of a suitable conductive-heat-transfer material is formed with small channels of a size selected to provide surface tension forces dominating a motion of a liquid-phase working fluid. A space above the channels of the substrate provides comparatively unobstructed space for the transport motion of a vapor phase of the working fluid effecting a heat-pipe effect in a multi-dimensional device. Channels may typically be formed in an orthogonal grid providing capillary return of liquids from a comparatively cooler condensation region to a comparatively warmer evaporation region, without any wicks other that the adhesion of the liquid phase working fluid to the vertices of the channels. Interference between the boundary layers of the liquid phase and the vapor phase of the working fluid are minimized by the depth of the channels, and the pedestals formed by the channel walls. Extremely small temperature differentials are thereby achieved between an outer surface of the substrate and an inner surface of the substrate when the liquid phase floods the substrate.

A composite panel provides structural strength and rigidity for modular assembly of spacecraft while serving the dual purposes of structure and heat transfer for thermal management of an environment for equipment, such as a spacecraft. Instruments, gimbals, surveillance, imaging, detectors, and the like may be mounted in a spacecraft designed and constructed from standard panels to provide the structural and heat transfer requirements to support the onboard equipment. Extremely small temperature differentials required by the panels support a substantially isothermal perimeter for the structure, able to sink heat from any location on a panel, transport it to a rejection site, and reject it to the cold environment of space, thus easing the task of design and packaging of instrumentation and infrastructure of satellites and other spacecraft. Two-phase mass transport of fluids inside the panels aids high heat flux rates with minimal temperature differentials, even with reinforced, composite, polymeric materials for the structural elements of the panels.

A panel assembly for exchanging heat with an ambient environment maintains minimal temperature differential by virtue of operation as a heat pipe apparatus. Panels of a composite material having excellent structural strength and structural stiffness but comparatively modest thermal conductivity are machined as mirror images of one another. Two orthogonal arrays of parallel channels are machined in the faces of two panels, each intersection of channels forming and bounded by pedestals having a lower, broader base with a narrower upper portion extending from a shoulder of the base portion of the pedestals. The pedestals, in turn, form the bounds of the channels, each having a deeper and a narrower aspect extending along the bases of all the pedestals. Channels have a broader aspect extending along near the tops of the pedestals.
