Abstract
Abstract Heat-transferring elements for regenerative heat exchange. The elements are embodied as rigid hollow spheres or balls, or as hollow polyhedrons, with the free inner space or chamber thereof being partially filled with a heat-conducting liquid as well as vapor from this liquid. The hollow sphere may be provided with an elastic outer shell with reinforcing elements arranged in the interior thereof. The heat-transferring elements may be utilized as a whirl layer and/or static layer.
