Abstract

Integral, thermal storage and receiver system. The system includes a heat storage medium and a receiver for capturing incoming radiation, the receiver being in thermal contact with the heat storage medium and forming an integral part of it. In a preferred embodiment, the storage medium is a molten salt and the receiver is a black body cavity formed of polyhedral structures and immersed within the molten salt.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An integral solar receiver-thermal storage system comprising:
 a heat storage medium; and   a receiver for capturing incoming radiation, the receiver being in thermal contact with the storage medium.   
     
     
         2 . The system of  claim 1  wherein the storage medium is a molten salt. 
     
     
         3 . The system of  claim 1  wherein the storage medium is selected from the group consisting of concrete blocks, metals, aggregates and graphite. 
     
     
         4 . The system of  claim 2  wherein the receiver is immersed within the molten salt. 
     
     
         5 . The system of  claim 1  wherein the receiver has a shape selected to maximize the capturing of incoming radiation. 
     
     
         6 . The system of  claim 5  wherein the receiver includes three hexahedral chambers of increasing volume. 
     
     
         7 . The system of  claim 1  wherein the receiver has a small opening to receive the incoming radiation. 
     
     
         8 . The system of  claim 1  wherein the incoming radiation is light. 
     
     
         9 . The system of  claim 7  further including a solar concentrator at the opening. 
     
     
         10 . The system of  claim 1  wherein the receiver includes fins of high thermal conductivity material in thermal contact with the heat storage medium. 
     
     
         11 . The system of  claim 10  wherein the high thermal conductivity material is copper or other medal or graphite. 
     
     
         12 . The system of  claim 1  wherein the receiver is a black body cavity.
