Original Abstract

One of the ways to increase efficiency of the solar absorber is modification of absorption area in the system of pyramidal cavities, where the incident radiation is absorbed by multiple reflections. The paper deals with the technology of production of the flow solar absorber with a structured surface in a single technological operations with hydroforming. Two laser-welded sheets is inserted into the forming chamber. Then the space between is pressurized with hydraulic fluid which causes their form to the desired shape. The first part of this article deals with theoretical simulations of forming a different structured surface in the programming environment of ANSYS. The second section describes hydroforming box. Follows practical test hydroforming. As a material for the production of samples is used austenitic stainless steel X5CrNi18-10.
