摘要： The invention is directed to an improved cryogenic cooler with an expander where the regenerator matrix is decoupled from the displacer or piston, thereby allowing the design of each to be optimized substantially independently. The regenerator matrix is preferably positioned spaced apart from the displacer and can be designed to enhance thermal exchanges and flow rates of the working gas. In one embodiment, the regenerator matrix has a serpentine shape or U-shape disposed around the displacer and the cold finger. Preferably, the regenerator matrix is static. The thermal lengths of the cold finger and/or the displacer can be extended by minimizing their geometrical lengths. Additionally, the structural integrity or stiffness of the cold finger and/or displacer can be strengthened.

摘要： A compact cryocooler includes a gas compression piston (304) supported for reciprocal linear translation along a first longitudinal axis (308) and a gas displacing piston (362) supported for reciprocal linear translation along a second longitudinal axis (366). The first longitudinal axis (308) and second longitudinal axis (366) are substantially orthogonal. A rotary motor (302) rotates a rotor (324) and associated motor shaft (320) about a motor rotation axis (328) disposed substantially parallel with the second longitudinal axis (366). Motor shaft (320) first and second mounting features (336, 340) traverse first and second eccentric paths around the motor rotation axis. A first drive coupling couples the first mounting feature (336) with the gas compression piston (304) and delivers a reciprocal linear translation along the first longitudinal axis (308) thereto. A second drive coupling couples the second mounting feature (340) with the gas displacing piston (362) and delivers a reciprocal linear translation along the second longitudinal axis (366) thereto.

摘要： The present invention relates to a cryogenic cooler's expander supported by a support member, preferably a truncated conical tube. The support member provides additional stiffness to the expander to reduce movements at the distal end of the expander. The support member also increases the natural frequency of the expander. In one embodiment, the support member increases the natural frequency of the expander at least about two (2) times in the bending and/or twisting sense. In another embodiment, the bending natural frequency of the expander and support sub-assembly is at least about two times greater or lower than the natural frequency of the electrical wires that connect the infrared sensor to a control processing unit to reduce the maximum stress applied to the electrical wires during use. In another embodiment, additional or redundant electrical pathways are provided for the connection between the infrared sensor and the CPU. Furthermore, shock absorber and/or shock diverters are provided on the rigid pins that connect the electrical wires to the CPU.

摘要： A refrigeration device includes a gas displacing piston (362) movable within a gas expander cylinder (364). The volume of a gas expansion space (362) is varied as the gas displacing piston (362) is moved over an expansion stroke range. The device includes a compression spring (622) disposed to bias the gas displacing piston (362) toward a compression stroke top end position (85). A cable element (606) extends into the gas expansion cylinder (364) and attaches to the gas displacing piston (362). A motive drive device (302) applies a tensioning force to the cable (606) and the tension force opposes the spring biasing force and moves the gas displacing piston (362) to a compression stroke bottom end position (83). In a further embodiment the expansion stroke is self-tuning when a pneumatic force generated by refrigeration gas contained within the expansion space (362) exceeds a threshold gas pressure and the pneumatic force overcomes the spring biasing force and pneumatically forces the gas displacing piston (362) to the bottom end position (83).
