DETAILED DESCRIPTION - The heat-shielding device comprises a plate-like, planar element, which has a surface facing a heat-dispensing heating unit and a surface facing away from the heat-dispensing unit. A circuit of flexible thermoelectric generators or a thermoelectric generator arrangement is arranged over a part of a region of a surface of the device, and a surface profile of the planar element is designed follow a curvature, a camber or a radius. The element has a cavity in which the thermoelectric generators or thermoelectric generator assembly is provided. The thermoelectric generator includes a pair of thermocouple legs (3) made from an n-doped semiconductor and thermocouple legs made from a p-doped semiconductor. The thermocouple legs are connected together in a series, and are provided with end connectors at their free end. The end connectors are arranged alternately at the free ends of the thermocouple legs. The thermocouple legs are arranged in a flexible matrix. The end connector is of metal sheet such as copper sheets, copper-plated or nickel-plated sheets. The metal plates are arranged in form-fit or with a slight interference fit to the free ends of the thermocouple legs. The thermocouple legs are moved in a longitudinal axis. An array of thermocouple legs and end connectors is arranged in rows or loops within the cavity of the device. The legs are connected by the end connectors without touching. The flat free ends of the n-or p-doped legs are lie to one another, and are soldered, bonded or sintered to one another, and separating layers are provided between the free ends. The p-and n-dopants are applied by three-dimensional printing and/or screen or offset printing and/or ink-jet process. The thermocouple legs have an L-shape, and are provided on a film-like substrate (2) by a sputtering method such as a physical vapor deposition method. The thermocouple legs are produced by applying a first material powder coating on the substrate, sintering the substrate to a desired shape by laser sintering, and applying a second powder to the substrate and then sintering to form the L-shape and removing the powder. The material is a thermoelectric material in the form of a cast film. The thermocouple legs are produced in the cast film.
