Abstract

PURPOSE: To promote absorbing efficiency by abosrbing multiple reflections on a number of projections fromed on a flat heat-resisting surface of metal for making up for losses mutually.
CONSTITUTION: On walls of projections 3 and the lower surface of base 1, a laminated layer 4 of metallic oxide is formed for constructing an absorbing face. Since the metallic oxide are laminated by an injection process to make the injected surface porous, light is collected and absorbed efficiently on walls of projections 3 and the injected face of the base, and converted into heat to be transmitted to thermal medium 5
