Giandomenico Lovato has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Heat exchanger particularly for thermal generators
    Patent number: 8783334
    Abstract: The present invention relates to a heat exchanger for transmitting heat from a gaseous primary fluid to a liquid secondary fluid. In particular, the present invention relates to the thermal exchange means proper, the main feature of which is the use of a diverging tube sheet including a plurality of four-lobe cross-section tubes.
    Type: Grant
    Filed: February 11, 2009
    Date of Patent: July 22, 2014
    Assignee: Ferroli S.p.A.
    Inventor: Giandomenico Lovato
  • Spiral heat exchanger for producing heating and/or sanitary use hot water, specifically designed for condensation applications
    Patent number: 8622030
    Abstract: A spiral heat exchanger for producing heating and/or sanitary use hot water, specifically designed for condensation applications, characterized in that said spiral heat exchanger comprises a duct, preferably though not exclusively made of a thermally conductive material and having a contoured cross-section, called outer duct, inside which can be either arranged or not a second duct, preferably though not exclusive made of a thermally conductive material, called inner duct; the geometrical construction of said outer duct being defined as a resultant obtained by joining two different diameter circumferences, said circumferences being spaced from one another by a constant or variable radius junction pattern; the thus obtained single or double duct being coiled or spiral wound on a diameter substantially larger than the size of said duct thereby providing a hollow cylinder.
