  • Electrical nucleation device for supercooled heat storage medium
    Patent number: 5378337
    Abstract: A device for electrically nucleating a supercooled melt of heat storage medium to artificially induce crystallization. The device includes a metallic electrode to which a rigid cover member is secured in tight mechanical contact therewith. A trace of a hydrate of salt forming the heat storage medium is retained in the form of molecular clusters between the electrode and the rigid member. Upon application of an electric voltage, the molecular clusters grow into crystal nuclei to trigger crystallization. A method of making the electrode assembly is also disclosed.
