  • Patent number: 9334761
    Abstract: An apparatus and method is disclosed wherein mechanical power is returned to a prime mover producing waste heat. The apparatus includes a working fluid configured to receive thermal energy from the waste heat, a collector to hold the working fluid, an evaporator fluidly coupled to the working fluid collector for transferring the waste heat to the working fluid to change the working fluid to vaporized working fluid, a feed pump to cause the working fluid to flow between the working fluid collector and the evaporator, an expander fluidly coupled to the evaporator to receive the heated working fluid to create rotational mechanical power, and a condenser to cool the expanded working fluid. The expander is mechanically associated with the prime mover directly or via a clutch.

  • Patent number: 7637108
    Abstract: A power compounder is disclosed. The power compounder comprises a working fluid configured to receive thermal energy from waste heat of a prime mover, a working fluid collector, an evaporator configured to transfer waste heat to a working fluid producing a phase change to vapor (or gas) in the working fluid, a double screw expander configured to receive the working fluid for creating rotational mechanical energy, and a condenser configured to produce another phase change in the working fluid to liquid. The double screw expander transfers the rotational mechanical energy via a shaft to the prime mover.
