摘要： An apparatus for exchanging heat with a fluid includes a heat exchanger having first and second opposing surfaces and a plurality of flow passages permitting axial fluid flow between the surfaces. A manifold having an interface surface is in thermal contact with the first surface and includes a thermally conductive body for conducting heat in an axial direction between the interface surface and a heat transmitting surface. A plurality of feed passages extend through the thermally conductive body in a transverse direction, the passages having an inlet for receiving or discharging fluid. A plurality of distribution passages have ends in fluid communication with at least one of the feed passages and openings distributed over the interface surface. The distribution passages are configured to cause a change in fluid flow direction between a transversely directed flow in the feed passages and an axially directed flow at the openings.

摘要： The apparatus includes a housing, a compression chamber disposed in the housing and having at least a first interface operable to vary a volume of the compression chamber, an expansion chamber disposed in the housing and having a second interface operable to vary a volume of at least the expansion chamber, and a thermal regenerator in fluid communication with each of the compression chamber and the expansion chamber. The thermal regenerator is operable to alternatively receive thermal energy from gas flowing in a first direction through the regenerator and to deliver the thermal energy to gas flowing in a direction opposite to the first direction through the regenerator. The compression chamber, the expansion chamber, and the regenerator together define a working volume for containing a pressurized working gas. Each of the first and second interfaces are configured for reciprocating motion in a direction aligned with a transducer axis, the reciprocating motion being operable to cause a periodic exchange of working gas between the expansion and the compression chambers. In one aspect, at least one of the first and second interfaces includes a resilient diaphragm, and a cylindrical tube spring coupled between the diaphragm and the housing, the tube spring being configured to elastically deform in a direction generally aligned with the transducer axis in response to forces imparted on the tube spring by the diaphragm to cause the at least one of the first and second interfaces to have a desired natural frequency. In another aspect the apparatus includes a first heat exchanger in communication with the expansion chamber, a second heat exchanger in communication with the compression chamber, the thermal regenerator is disposed between the first and second heat exchangers, and each of the first and second heat exchangers are peripherally disposed within the housing with respect to the transducer axis and configured to receive working gas flowing to or from the respective chambers and to redirect the working gas flow through the regenerator.

摘要： A thermoacoustic transducer includes a mechanical converter providing power conversion between acoustic and mechanical power and includes a diaphragm defining a compression and an expansion chamber. A thermal converter including a flow passage having a regenerator portion is thermally coupled for conversion between acoustic and thermal power. The mechanical converter is in fluid communication with the flow passage through transmission ducts completing an acoustic power loop having a volume containing a working gas. A transmission duct cross-sectional area is less than a regenerator flow area, which is less than a diaphragm surface area. The diaphragm undergoes resilient displacement causing pressure oscillations within the volume. The power loop is configured to cause one location along the loop to have anti-phase pressure oscillations to pressure oscillations in the mechanical converter.

摘要： A thermal regenerator apparatus is disclosed including a regenerator medium having a plurality of flow passages extending between first and second ports, the flow passages facilitating back and forth fluid flow in a generally transverse direction between the first and second ports while the medium alternatively receives thermal energy from and delivers thermal energy to the fluid. The regenerator medium includes a plurality of overlying foils, each foil having a plurality of channels extending through the foil, the channels having beveled sidewalls. The channels have a width and spacing in the transverse direction and channels in each adjacent overlying foil are transversely offset such that each channel spans between and is in fluid communication with a pair of channels in the adjacent foils and the beveled sidewalls of the channels redirect fluid flow between channels in adjacent foils to form the flow passages. The channels are elongated along the foil in a longitudinal direction orthogonal to the transverse direction and divided by foil bridges extending transversely, the foil bridges being sized to reduce thermal conduction through the medium in the transverse direction.

摘要： An electromechanical transducer apparatus is disclosed and includes a housing. A static portion is substantially immobilized within the housing and includes a magnetic flux generator for generating magnetic flux, a pair of pole pieces for coupling magnetic flux through at least one of a first magnetic circuit and a second magnetic circuit, and a coil disposed to electromagnetically interact with one of the magnetic circuits. The static portion is thermally coupled to the housing via a low thermal resistance path to permit removal of heat. A movable portion includes first and second closing pieces separated from the pole pieces by first and second gaps. The closing pieces are mechanically coupled and supported for reciprocating motion about an equilibrium position which varies the gaps to cause a variation in magnetic reluctance in each of the first and second magnetic circuits.
