摘要： A monolithic heat exchanger body for inputting heat to a closed-cycle engine includes heating walls and heat sink, such as heat transfer regions. The heating walls are configured and arranged in an array of spirals or spiral arcs relative to a longitudinal axis of an inlet plenum. Adjacent portions of the heating walls respectively define corresponding heating fluid pathways fluidly communicating with the inlet plenum. At least a portion of the heat sink is disposed about at least a portion of the monolithic heat exchanger body. The heat sink includes working-fluid bodies including working-fluid pathways that have a heat transfer relationship with the heating fluid pathways. Respective ones of the heat transfer regions have a heat transfer relationship with a corresponding semiannular portion of the heating fluid pathways. Respective ones of the heat transfer regions include working-fluid pathways fluidly communicating between a heat input region and a heat extraction region.

摘要： A microminiature Stirling cycle engine or cooler is formed utilizing semiconductor, planar processing techniques. Such a Stirling cycle thermomechanical transducer has silicon end plates and an intermediate regenerator. The end plates are formed with diaphragms and backspaces, one end plate forming the expansion end and the opposite end plate forming the compression end, with the regenerator bonded in between. A control circuit apparatus is linked to the diaphragms for controlling the amplitude, phase and frequency of their deflections. The control circuit apparatus is adapted to operate the transducer above 500 Hz and the passages and the workspace, including those within the regenerator, expansion space and compression space, are sufficiently narrow to provide a characteristic Wolmersley number, which is characteristic of the irreversibilities generated by the oscillating flow of the working fluid in the workspace, below substantially 5 at the operating frequency above 500 Hz. Additionally, the amplitude of the vibrations of the diaphragm vibrations are sufficiently small to provide the working fluid a maximum Mach number below substantially 0.1 at an operating frequency above 500 Hz.

摘要： A thermal lag engine has a cooled cylinder and piston connected to a heated chamber. A working fluid in the cooled cylinder and heated chamber is alternately compressed and expanded by the piston. Since there is a thermal lag or time interval before the working fluid entering the hot chamber is heated and the working fluid expanding back into the cooled cylinder is cooled, the working fluid is at a lower average temperature and pressure during compression and a higher average temperature and pressure during expansion to provide net work.

摘要： A Stirling engine having a cooler, regenerator and heat exchanger stacked end to end along with a working cylinder position adjacent to the heat transfer stack and connected thereto by several connecting ducts. By using more than one hot connecting duct, their bending stiffness is less as compared with a single duct being the same area as the multiple ducts, allowing thermally induced relative displacement between the elements to occur. The heat exchanger includes a plurality of axially extending tubes spaced apart from one another with a combustor positioned adjacent to the tubes such that the combustion gases flow between the tubes. The tubes are preferably flattened in the direction of the gas flow between them to increase the surface area for heat transfer. Furthermore, wire is coiled around and brazed to the tubes creating a fin for additional heat transfer. A gas flow restrictor is positioned around the heat exchanger tubes over a portion of their lengths in order to produce isothermal heating of the tubes. The combustor has a number of tangential air flow inlets which mixes air with a combustible fuel injected from a nozzle providing a highly turbulent combustion gas flow.

摘要： In a hot gas or Stirling engine conventional regenerators for engines with a large displacement, designed for axially directed flow and usually lacking sufficient mechanical strength with respect to the high working gas pressures, have been replaced by radial flow regenerators. In the respective receiving spaces, the radial flow regenerators are surrounded externally and internally by an annular duct for the supply and discharge of the working gas. Thus, it is possible to ensure a larger flow area for the working gas and to design the engine with the desired mechanical strength.

摘要： A piston engine comprising a piston movable in a recriprocating manner in a cylinder, while during operation a wedge-shaped gap is present between piston and cylinder. The piston divides the cylinder into a first chamber and a second chamber, which communicate with each other through the gap. A stable central position of the piston is obtained by means of the wedge-shaped gap, which mainly determines a pressure difference between the first chamber and the second chamber. A particular application of the piston engine is a cryo-cooler, by means of which, for example, processors of computers are cooled.

摘要： A regenerative heat exchanger in which a compact arrangement of alternating thermally conductive and thermally insulating solid layers have an array of communicating passages therethrough. One of the outer thermally conductive layers is heated and the other is cooled. The intermediate thermally conductive layer(s) has a regenerative function when flow is alternated through the passages. Although each passage is preferably small, the total number of passages in the array is such as to give a large combined cross-sectional area for heat transfer providing improved overall performance and efficiency when incorporated in stirling and other heat engines without sacrificing structural integrity.
