Thermal energy storage device

Abstract

A heat-storage battery device, comprises a cover, closing components, and an inner separating surface that along with said cover, defines an inner volume that provides a continuous pathway for materials inside the inner volume of the device, and simultaneously allows for enhanced melting.

1 . A heat-storage battery device, comprising a cover, closing components, and an inner separating surface that along with said cover, defines an inner volume that provides a continuous pathway for materials inside the inner volume of the device. 
     
     
         2 . A device according to  claim 1 , wherein the inner separating surface is suitable to allow close-contact melting (CCM) of the phase-change material above it. 
     
     
         3 . A device according to  claim 1 , wherein the separating surface is shaped as a helix. 
     
     
         4 . A device according to  claim 1 , further comprising a pipe. 
     
     
         5 . A device according to  claim 4 , wherein the separating surface is provided around the pipe. 
     
     
         6 . A device according to  claim 4 , wherein the inner volume of the pipe is suitable to allow a fluid to flow therein. 
     
     
         7 . A device according to  claim 6 , wherein the fluid is liquid. 
     
     
         8 . A device according to  claim 6 , wherein the fluid is gas or steam. 
     
     
         9 . A device according to  claim 1 , wherein the closing components are adapted to seal the inner volume of the device from the environment. 
     
     
         10 . A device according to  claim 1 , wherein the cover and the separating surface are in contact.
