One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

Method for controlling heat transfer between a mainly solid base and the ambient medium

This invention belongs to the field of construction of shielding and heat-shielding structures. The technical result is changing the degree of useful effect from the regulation of heat transfer depending on the temperature of the plates of the heat control structure.

In the method for regulating heat transfer between a mainly solid base and ambient medium, one plate (2) or at least two plates (2, 5) stacked in layers and interconnected are installed on base (1) at rest temperature, while at least one (2) of the said plates, when its temperature changes relative to the rest temperature, is capable of deforming so that a cavity is formed between this plate and the base or the plate adjacent in the layer, filled with particles of the ambient medium, and fixation points (3) of plate (2) to base (1) or plate (5) adjacent in the layer are selected so that this plate (2) takes a convex shape during deformation.
