Solid material heat accumulator module for transfer of heat in e.g. thermal oil for solar-thermal power plant, has plug-in structure embedded into solid material body and releasably inserted into fluid guide pipe in heat conductive manner

摘要

The module has a solid material body embedding a heat conductive structure (7). The heat conductive structure contacts the solid material body. The heat conductive structure is formed by a plug-in structure of plug-in elements (71, 72). The plug-in elements are different relative to cross-sections. One of the plug-in elements is linked with another plug-in element to form the plug-in structure. The plug-in structure is embedded into the solid material body and releasably inserted into a separate fluid guide pipe (6) in a heat conductive manner. The solid material body is made of hardening material e.g. concrete or mortar or ceramic. Independent claims are also included for the following: (1) a method for manufacturing a solid material heat accumulator module (2) a solid material heat accumulator.
