摘要： Some heat pumps have displacers mechatronically-controlled via springs and coils acting upon a ferromagnetic plate. In some prior art heat pumps, the components are housed in hot parts of the heat pump and in others, the components are housed in a cold part of the heat pump, but the components are offset from a central axis of the heat pump. A heat pump with the mechatronic driver components collinear with a central axis of the heat pump has the components in a cold part of the heat pump.

摘要： A thermodynamic apparatus, such as a Stirling engine or a Vuilleumier heat pump, has a heat exchanger in which energy is exchanged between a working fluid and an exhaust gas stream. On top of the cylinder of the thermodynamic apparatus is a dome-shaped section. By incorporating the heat exchanger within the dome, the flow paths can be simplified, the number of separate components reduced, and overall weight reduced. Flow passages for the working fluid are embedded in the dome. Channels for the exhaust gases are formed in an outer surface. The passages and the channels are helically arranged, one clockwise and one counter clockwise. The dome can be cast with a core for the casting fabricated via three-dimensional printing. In some embodiments, the dome is made of fiber-reinforced material.

摘要： Reciprocating apparatuses such as a displacer in a Stirling engine or Vuilleumier (thermally-driven) heat pump and such as a poppet valve in an internal combustion engine have been known to be built with a mechatronic actuator. The reciprocating element has two springs in compression biased against each other. It has been found that conventional springs in compression introduce losses. A spring is disclosed in which a portion of the coil is wound in a clockwise direction and a portion is wound in a clockwise direction. Also, in reciprocation, the spring is in compression at one end of travel and in tension at the other end of travel.

摘要： An annular heat exchanger is disclosed that uses a spiral of a metallic ribbon that has a plurality of passages therein. The spiral is wound in such a manner such that there are gaps of a predetermined distance between adjacent turns. A plurality of spacers is put into the gaps at a first angular position and a second angular position. The assembly is brazed to form a solid between the spacers and the spiraled metallic ribbon. Inlet and outlet holes are machined through the spacers and the ribbon thereby fluidly coupling the passages in the ribbon with the holes. One of the fluids passes from the inlet hole to the outlet hole through one of the plurality of passages. The other fluid flows through the remaining gap areas between the turns of the metallic ribbon.

摘要： A gas-fired heat pump that has independently-actuated displacers, as opposed to crank coupled displacers, has some displacer strokes that require more energy than others to travel. By coupling the displacers by a spring, the forces to move the displacers are more evenly matched. A gas spring coupled between the displacers is disclosed in which volume with the gas spring includes: a portion of the volume within the hot displacer, a portion of the volume within the cold displacer, and a volume between the two displacers. Also disclosed is a bridge that spans across the housing between the hot and cold displacers. The forces acting on the displacers via the gas spring are based on pressure in the gas spring and the cross-sectional areas of plungers on the hot displacer, the cold displacer, and the bridge.

摘要： A heat exchanger and a method to fabricate a heat exchanger are disclosed. A brazing compound is applied to a surface of a host piece, such a host cylinder. A flat, rectangular piece of metallic material is corrugated and crushed to form pluralities of crests and troughs. The troughs are flattened before abutting with the brazing compound on the host cylinder. The crushed folded fin is brazed to the host cylinder. In some embodiments, a folded fin is brazed to both the inside and outside cylindrical surfaces of the host cylinder. The resulting heat exchanger has high effectiveness and is low cost.
