Low void fraction thermal storage articles and methods

摘要

Low void fraction thermal energy storage articles, systems, and methods for making and using such thermal energy storage articles and systems. Thermal energy storage units include a thermal energy storage body having a particular void volume and a mixing cavity-creating element. Thermal energy storage modules include two or more thermal energy storage bodies arranged adjacently with an intervening cavity defined by a cavity-creating element. The total void volume of a thermal energy storage module (i.e., the sum of the void volume of the passages of the thermal energy storage bodies and the cavity) is between about 10% and about 40%.
