Abstract: A hollow evaporator is disposed in contact with the upper surface of the CPU. Heat from the CPU is absorbed by the evaporation of the refrigerant. The vaporized refrigerant ascends through the vapor flow channel by convection, flows into a condenser located above the evaporator, and radiates heat to be liquefied. The liquefied refrigerant flows down by its own weight through the liquid flow channel and returns to the evaporator. This circulation is repeated in this manner.

Abstract: An improved free piston Stirling machine having a gamma configuration. The displacer and each piston is reciprocatable within a cylinder having an unobstructed opening at its inner end into a common volume of the workspace. The common volume is defined by the intersection of inward projections of the displacer cylinder and the piston cylinders. The displacer and the pistons each have a range of reciprocation that extends into the common volume. A displacer drive rod is reciprocatable in a drive rod cylinder and both are positioned outside the common volume and on the opposite side of the common volume from the displacer. The displacer is connected to the displacer drive rod by a displacer connecting rod. Importantly, the displacer and pistons have complementary interfacing surface contours formed on their inner ends which substantially reduces the dead volume of this gamma configured machine.

Abstract: A linear alternator capable of delivering multi-phase power and yet being driven by a free piston Stirling engine. The alternator has a permanent magnet mounted to the power piston of the free piston Stirling engine and an armature coil member mounted radially outwardly from the piston cylinder for generating one phase. A body, such as a second piston mounted in the same cylinder, is drivingly linked through a spring to be driven by the power piston. A second permanent magnet is mounted to the body and a second armature coil member is formed outwardly of the cylinder disposed outwardly from the body to provide the second phase. Proper design selection of the mass of the body and the spring constant of the spring, together with all other springs connected to the body, causes the body to be driven in phase quadrature with the power piston so that the voltage outputs of the two phases are in quadrature. The armature coils are provided with suitable taps and connected as a Tee so that balanced three phase power is available directly from the armature windings of the linear alternator.

Abstract: A free-piston Stirling machine drivingly coupled to at least one rotary electromagnetic transducer. At least one pulley is oriented in a plane of a reciprocating piston connecting rod. At least one motion translating drive link connects the connecting rod to the pulley by at least two straps so that the pulley moves in rotationally oscillating motion. The two straps extend along an arcuate surface of the pulley into connection to the piston rod at two spaced locations. The pulley is linked to a rotary electromagnetic transducer so that both move in rotationally oscillating motion. Preferably a piston spring resonates the piston at an operating frequency of the Stirling machine and a torsion spring resonates the pulley in rotational oscillation at the operating frequency of the Stirling machine.

Abstract: To provide a less expensive and high-efficient free-piston Stirling cycle machine with an outer diameter of entire machine being relatively small. In a Stirling cycle cooler as a free-piston Stirling cycle machine including a cylinder 7, a piston 18 which is reciprocable inside said cylinder 7 and an electromagnetic driving mechanism 19 for reciprocating said piston 18, said electromagnetic driving mechanism 19 is comprised of a mover 20 and a stator 35, said piston 18 and said mover 20 formed by disposing a permanent magnets 24 outside an inner yoke 23 made of magnetic flux conducting material are disposed in an axial alignment, and said stator 35 and said cylinder 7 are disposed in an axial alignment. By this disposition, the outer diameter Rm of said mover 20 of said electromagnetic driving mechanism 19 can be reduced, and consequently the inner diameter Rs and the outer diameter of said stator 35 provided outside said mover 20, eventually the outer diameter of entire Stirling cycle cooler can also be reduced.
