Juan Cepeda-Rizo 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).

  • Patent number: 10116258
    Abstract: The efficiency of solar power collection is increased by adding a thermal energy storage stage to a sunlight concentrator and thermodynamic power generator system. The thermal energy storage includes tubes or capsules made of a phase change material that stores thermal energy in different temperature stages through a working fluid. The stored thermal energy is directed to the thermodynamic generator during off-sun periods.
    Type: Grant

  • Patent number: 9464638
    Abstract: An automotive cabin cooling system uses a bladeless turbocompressor driven by automobile engine exhaust to compress incoming ambient air. The compressed air is directed to an intercooler where it is cooled and then to another bladeless turbine used as an expander where the air cools as it expands and is directed to the cabin interior. Excess energy may be captured by an alternator couple to the expander turbine. The system employs no chemical refrigerant and may be further modified to include another intercooler on the output of the expander turbine to isolate the cooled cabin environment.

  • Patent number: 7285851
    Abstract: In one embodiment, a liquid immersion cooled multichip module is provided which includes a substrate having chips mounted thereon and which is adapted to mount with a printed circuit board. A lid is adapted to secure to the printed circuit board so as to mount with the substrate to form a fluid chamber between the lid and the substrate, and to cause the substrate to mate with the printed circuit board. In one embodiment, a cambered bolster plate is located on a side of the printed circuit board opposite the lid and the lid is fastened to the bolster plate to secure the lid to the printed circuit board. A baffle, which may be removable in some embodiments, is located within the lid and directs coolant flow through the fluid chamber.
