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.
