Abstract
A two layer system for heat energy capture and storage with an upper or lower layer for heat extracting and the other layer for heat transfer. Either layer can function as a phase change material. Heat stored is conducted externally of the system and can be used directly in a converting system, i.e., heat to mechanical or electrical energy or transferred as heat for further applications.
Claims54
A two layer heat storage system comprising two layers in contact with each other where one layer is a heat storage layer and the other layer is an intermediate phase layer used for extracting heat,
- wherein the heat storage layer is a phase change layer, in which a solid form of the phase change layer has a density lower than a liquid form of the heat phase change layer, and
- the intermediate phase layer is a liquid metal layer having a density higher than both phases of the phase change layer.
A two layer heat storage system comprising two layers in contact each other where one layer is a heat storage layer and the other layer is an intermediate phase layer used for extracting heat, wherein the liquid metal layer is separated from the heat storage layer by a baffle, whereby solar energy is directly received and absorbed by the heat storage layer.
A two layer heat storage system comprising two layers in contact each other where one layer is a heat storage layer and the other layer is an intermediate phase layer used for extracting heat, wherein the liquid metal layer has a transparent top to allow penetration of solar energy into the liquid metal layer.
A two layer heat storage system comprising two layers in contact each other where one layer is a heat storage layer and the other layer is an intermediate phase layer used for extracting heat, wherein the intermediate phase layer is placed below the heat storage layer.
