Patent number: 8607579Abstract: Embodiments of a heat transfer apparatus, and related methods, involve at least one boundary wall defining a first flow path through a neck portion, a first heat source external to and in thermal communication with the boundary wall, and a working fluid (e.g., a first fluid component with a second fluid component entrained therein).

Patent number: 8281605Abstract: Embodiments of a heat transfer apparatus, and related methods, involve a curved flow path, a heat source external to and in thermal communication with at least a portion of an inner radial boundary of the curved flow path, and a working fluid, including a heavier component and a lighter component, flowing through the flow path. The flow path causes the working fluid to experience centrifugal force so as to preferentially force the heavier component toward the exterior wall portion and thereby cause the lighter component to preferentially absorb heat from the interior wall portion.Type: GrantFiled: April 8, 2009Date of Patent: October 9, 2012Assignee: Machflow Energy, Ing.Inventors: Arthur R. Williams, Charles Agosta

Patent number: 7918094Abstract: Heat pumps move heat from a source to a higher temperature heat sink. This invention enables spontaneous source-to-sink heat transfer. Spontaneous heat transfer is accomplished by conducting heat from the source through rotating disks to a portion of the generally warmer sink flow that is cooled to a temperature below that of the source by the Bernoulli effect. The nozzled flow required for Bernoulli cooling is provided by the corotating disk pairs. The distance between the opposing surfaces of the disk pair decreases with distance from the rotation axis, forming a nozzle. The heat-sink flow through the nozzle is maintained by centrifugal force caused by the circular motion of the gas near the disk surfaces. Embodiments of the invention differ in the paths followed by the source and sink fluid flows, by the number of disk pairs and by the state (gas or liquid.) of the heat source.Type: GrantFiled: March 9, 2006Date of Patent: April 5, 2011Assignee: MachFlow Energy, Inc.Inventors: Arthur R.

Publication number: 20090183858Abstract: Heat pumps consume power in order to transfer heat from a source to a higher-temperature sink. This invention enables spontaneous heat transfer from a heat source to a small portion of the generally warmer working fluid that is cooled locally by the Bernoulli effect to a temperature below that of the heat source. The Bernoulli effect occurs in a Venturi shaped duct shaped to maintain attached flow. Heat-transfer efficiency is improved by restriction of the heat transfer to a small portion of the Venturi in which the flow temperature, velocity, pressure gradient and the Nusselt effect enhance heat transfer. Within this region, heat transfer is maximized by a thermally conducting grid extending across the Venturi neck.Type: ApplicationFiled: June 23, 2006Publication date: July 23, 2009Inventors: Arthur R.

Publication number: 20080028774Abstract: Heat pumps move heat from a source to a warmer sink, with Bernoulli heat pumps accomplishing this movement by reducing the temperature in a portion of the generally-warmer heat-sink flow. Heat flows spontaneously from the generally cooler heat-source flow into the locally cold portion of the heat-sink flow, which is the neck of a Venturi. The temperature reduction results from the Bernoulli conversion of random gas-particle motion (temperature and pressure) into directed motion (flow). This invention is a Bernoulli heat pump in which the heat transfer into the Venturi neck exploits unusual thermodynamic transport properties of rare-gases. Rare gases, especially mixtures of them, possess unusually small Prandtl numbers and thereby facilitate the diffusion of random particle motion (heat) relative to the diffusion of directed particle motion (viscosity), viscous friction being responsible for most of the power consumed by a Bernoulli heat pump.Type: ApplicationFiled: August 3, 2006Publication date: February 7, 2008Inventors: Arthur R.
