Abstract: An improvement is provided to a pressurized close-cycle machine that has a cold-end pressure vessel and is of the type having a piston undergoing reciprocating linear motion within a cylinder containing a working fluid heated by conduction through a heater head by heat from an external thermal source. The improvement includes a heat exchanger for cooling the working fluid, where the heat exchanger is disposed within the cold-end pressure vessel. The heater head may be directly coupled to the cold-end pressure vessel by welding or other methods. A coolant tube is used to convey coolant through the heat exchanger.

Abstract: An outer plastic tube has water connections through the wall into an arcuate space defined by an O-ring spacer-gasket positioned between the wall and the perimeter margin of an inner cylinder rolled from a single-layer of sheet metal. A metal drainpipe with a removable bullet-shape at one end is forced through the cylinder to expand it and to thereby compress the gasket sealing the arcuate space. Thermal contact conductance is increased by the compressive force of water pressure. Water flow through the heat exchanger is both arcuate and turbulent to optimize heat transfer.

Abstract: A waste heat exchanger may include an inner tube, an outer tube, a fin assembly and a plurality of heat electric modules The inner tube has a plurality of holes. Disposed inside the inner tube is a plurality of inlet channels and a plurality of outlet channels. The plurality of inlet channels and the plurality of outlet channels are disposed to correspond to each other. The plurality of inlet channels and the plurality of outlet channels are connected to the plurality of holes. A fluid flows through the plurality of inlets and the plurality of holes to get into the outlet channels. The outer tube is disposed outside the inner tube. The conductive assembly is positioned between the inner tube and the outer tube. The conductive assembly is disposed on an outside surface of the inner tube and an inside surface of the outer tube.

Abstract: A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be radially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.
