UK Patent Application
Gideon Stewan Kukard & Maria Fernanda Kukard
Solar Heat Exchanger Utilising Graphene Foam
A solar hear excahnger comprises a fused quartz glass tube containing graphene foam and water, where the water, which is to be heated by solar energy; is in direct contct with the Graphene foam. In operation, the graphene foam is designed to absorb energy from incident sunlight, heat up, and transfer the heat into the surrounding water/ Preferably, the glass tube comprises of a inner tube and outer tube, with a vacuum maintained in the space between the inner and outer tubes so as to minimise heat and to maximize heat absorbtion. A further graphene coating may be included on the inside surface of the inner tube. Water may be pumped through the inner tube of the heat exhanger and around the graphene foam. The graphene foam may include a metal substrate, which can either be melted out to leave the graphene foam as the only structure or left in place to make the foam a darker colout for improved solar absorption. Preferably the graphene foam comproses of a rolled up sheet or stacked layer of graphene. A Fresnel lens may be used to concentrate solar energy onto the heat exchanger.
